Title: An improved overhead electric line and conductor therefor
Inventor: BRAZIER LESLIE GIDDENS
IPC: H01B5/10
Filed: 1950-08-29
Abstract: 687,084. Overhead cables; sleeve couplings. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Aug. 28, 1951 [Aug. 29, 1950], No. 21365/50. Classes 36 and 38 (i). An overhead line conductor comprises a central stranded mem. ber 1 of high tensile strength metal, a layer 4 of non-metallic filling material and a thin-walled metal tube 5 of low density and high conductivity, this tube having a smooth circumferentially continuous wall with a smooth circular outer surface and fitting closely on the covering layer. The central member 1 may be of steel and may be surrounded by layers 2, 3 of aluminium wires. The filling 4 may comprise lappings of paper tape, or cords of paper or hemp. The tubular conductor 5 may be extruded directly on the filling material, by bending a metal strip about the filling material and welding the edges together, or by drawing the core into a preformed tube which is then shrunk to fit tightly on the core. The inner and outer parts of the conductor are electrically connected together at intervals, such as at the joints between adjacent lengths. A joint may be made by cutting back the outer layers of adjacent conductor ends, to expose the underlying layers as shown in Fig. 3. A metal sleeve 9 is slipped over the projecting ends of members 1, 1<SP>1</SP>, and compressed thereon. A split metallic tube 10 is placed over sleeve 9 and exposed ends of layers 2, 2<SP>1</SP>, and a second split metallic tube 11 is placed over tube 10 and exposed ends of layers 3, 3<SP>1</SP>. A sleeve 12, previously slipped over one of the cable ends, is brought into position over the joint and compressed to make good metallic contact with the underlying tubes. The filling material 4, 41 may be removed for a short distance beneath the ends of tubes 5, 5<SP>1</SP> and replaced by metal sleeves 13, 131 grooves at 14, 14<SP>1</SP> to permit slight inward compression of tubes 5, 5<SP>1</SP> and sleeve 12 at those points. Instead of tubes 10, 11, a single tube having a stepped bore, or a wrapping of sheet-metal or wire may be used.

Title: Arrangement for modifying the spectrum emitted by a source of artificial light
IPC: F21V9/40
Filed: 1949-08-18
Abstract: 671,687. Electric lamps; reflectors. MALIFAUD, P. Aug. 18, 1949, No. 21492/49. Classes 39(ii) and 75(ii) In an illuminating device a reflector which reflects only part of the spectrum of the light emitted by the source is arranged so that for each direct ray there is a coincident reflected ray and all the reflected rays pass through the source. The reflector shown is of spherical form and has transparent and reflecting segments which are arranged alternately and so that each reflecting segment 5 is diametrically opposite a transparent segment 6 ; a point light source 1 is at the centre. In another embodiment the reflector is a continuous hemispherical reflecting surface and a point light source is disposed at its centre. In a further embodiment the reflector is semiellipsoidal and a light source of small length is arranged with its ends at the foci. The reflector may be semi-cylindrical with a light source extending along its axis and the transverse section of the reflector is semi-circular or semi-elliptical corresponding to a source having a transverse section which is either a point or a line of small length. The hemi-spherical or semi-ellipsoidal reflectors may be sealed to the outside of a light bulb or they may be supported inside the bulb by stiff wires or transparent arms on the filament carrier. The reflectors are of bluish-violet colour and reflect only wavelengths between 4,000 and 6,000 Anstrom units. The colour may be imparted by incorporating salts of cobalt in the reflector surface material.

Title: Improved diffraction gloniometer
IPC: G01N23/207
Filed: 1965-05-21
Abstract: 1,089,975. Diffraction apparatus. CHIRANA PRAHA NARODNI PODNIK. May 21, 1965 [May 23, 1964], No. 21584/65. Heading H5R. A diffraction goniometer is arranged to operate on both the central (Bragg-Brentano) and the tangential (Seemann-Bohlin) focusing principles. The apparatus includes a rotatable crystal or specimen at the central S 1  of focusing circle K 1  on the circumference of which is situated the focal point F of the X-ray source. The detector having a slit S, is mounted on a base-plate P movable along an arm R 1 , rotatable about the centre of circle K 1 . In operation on the central principle, the detector is located in one position on the arm R 1 , and travels along the circumference of circle K 1  as rotation of the crystal necessitates. The apparatus also includes an auxiliary arm R 2  rotatable about an axis at one end, this axis being on the circumference of circle K 1  and equidistant from the focal point F and the crystal axis S 1 . In operation under the tangential principle, the end of the arm R 2 , which travels round a further focusing circle K 2 , engages the detector baseplate and as it rotates, slides the detector along the arm R 1  so that the detector travels around circle K 2  rather than that K 1 . This causes the crystal to remain tangential to circle K 2  and the detector to move into the required positions on circle K 2  to receive rays from the crystal. The link between the drives for arms R 1  and R 2  is provided by means of helical gears (SK 1  and SK 2 ) which rotate about the centres of circles K 1  and K 2 , respectively and which in the tangential principle of operation can be connected by displacement of a worm drive (S n ) which then engages with the gear (SK 2 ) (Fig. 5, not shown). The invention has equal application with other radiations besides X-rays, e.g. γ- rays, neutrons.

The latching means are formed on integral vertical corner posts 14 which have mating recesses 16 and tabs (18), Fig. 3 (not shown), to facilitate stacking and holes 19 to enable standard lifting hooks or clevis pin arrangements to be used. Stacked container modules are secured together by overcentre latches 22 and catches 24. The bases of the posts 14 project beneath the base of the container 10 to facilitate entry of fork lift truck tines. The latching means 26 may comprise a bridge member 28 pivotally mounted on a sleeve 30 which is eccentrically mounted on a shaft 32 secured between flanges 34 and 36 on one post 14, two holes 42, 44 in flanges 46, 48 in an adjacent post 14, and a pin 50 passing through the holes 42, 44 and a bore 40 in the beam 28. To compensate for misalignment between the adjacent containers the shaft 32 is rotated to displace slightly the centre of the sleeve 30 thus moving the member 28. The sleeve 30 is locked in position by a plate 62 having a knurled opening 64 which is telescoped over a knurled sleeve 60 on the shaft 32. When not in use, the member 28 lies against its own post 14, the pin 50 passing through holes 56, 58 in the flanges 34, 36 and the bore 40. The latching means 26 may comprise a conical element (80), Fig. 6 (not shown), threaded on to a bolt (81) pivotally supported by one post 14 and a conical bore (88) formed in the post and aligned with a conical bore (90) in an adjacent post, the conical element passing through both bores and being tightened to secure the posts together. Again, the latching means may comprise a handle (192), Fig. 7 (not shown), pivotally mounted on one post 14, a hook (98) pivotally mounted on the handle, the pivots for the hook and handle being spaced, and a pin (102) on the other post 14 which is engaged by the hook by an over-centre operation of the handle. The parts 25 of the latching means 26 are arranged at the top right hand corner and bottom left hand corner of each side of the container and the parts 27 of the latching means 26 are arranged at the top left hand corner and bottom right hand corner of each side so that the container modules can be connected in several orientations.

Title: Improvements in or relating to methods of Embedding together Elongate Elements and Embedded Elements produced by said methods
IPC: B65B55/20
Filed: 1967-05-10
Abstract: 1,164,900. Bundling. SCHWEIZERISCHE ISOLA-WERKE. 10 May, 1967 [10 May, 1966], No. 21690/67. Heading B8C. A method of binding together articles such as coils of wire or bundles of rods comprises introducing an expandible substance into the voids and treating it to cause expansion and bridging between voids. The coil or bundle may be placed in a mould 5 prior to expansion of the substance, the latter being introduced either during or after the piling of the coils or rods into the mould. The substance or a component of an expandible mixture may comprise or be on a carrier, e.g. paper sheets or strips arranged between layers or coils. They may be applied by dipping when in liquid form or by vibratory feed when of a granular character. The articles may be pre-treated to prevent adhesion to the substance. Foamable plastics or latex may be employed. The substances may be protective or a protective coating may be applied.
Patent GB-1107574-A (GB)
Title: Method and apparatus for the electrostatic sorting of granular materials
IPC: F26B21/06
Filed: 1965-05-21
Abstract: 1,107,574. Combined pneumatic and electrostatic separation of solids. SOCIETE ANON- YME DE MACHINES ELECTROSTATIQUES. 21 May, 1965 [21 May, 1964; 18 Jan., 1965], No. 21730/65. Headings B2H and B2J. A mixture of substantially non-conducting particles to be sorted is continuously fed from a hopper 10, Fig. 1, by a screw 12 onto a perforated or porous wall 6 spaced from the bottom 4 of a tank 2 and made of electrically conductive or semi-conductive material such as sintered powder metals. Heated compressed air is 'blown via a pipe 8 through the wall 6 to produce a fluidized bed of the particles which as a result of their agitation, become electrostatically charged by contactor frictional electrification whereby charges of different polarities are imparted to particles of different constituents. An extracting electrostatic field is established between the wall 6, which is connected to the positive terminal of an electrostatic generator 34, and a grounded conductive conveyor belt 18. The positively charged particles of one or more of the constituents are attracted by the lower stretch 24 of the conveyor belt 18 from which they are brushed off into a collecting trough 26. The negatively charged particles of the other constituents remain in the tank 2 and are discharged through a calibrated outlet 14. As shown; the conveyor belt 18 is longitudinally offset from the input end of the tank 2 in order to provide in the tank an initial pre-charging zone in which no extracting field is present and in which the particles have the opportunity to become effectively charged. The wall 6 may consist of a rigid porous metal plate or of a fine-mesh wire screen. The effectiveness of the charging process may be enhanced by vibrating the fluidized bed by means of a vibrator unit 38 connected to the bottom wall 4 of the tank and by means of partition walls 40 which may or may not extend right to the side walls of the tank and which serve to transmit the vibrations to the interior of the bed and especially when made of epoxy resin, to transfer charge carriers between the particles of the different constituents of the mixture. Instead of partition walls, spaced cross-bars 41, Fig. 2, of poorly conductive or insulating material may be used. A grounded horizontal plate electrode 19 is positioned above the lower stretch 24' of the conveyor belt 18' which is made of poorly conductive material. Electrification of the particles may be further improved by introducing small spheres or beads of epoxy resin 42 in the tank 2 where they remain permanently and are free to move at random among the particles. An overflow-type outlet 41' is provided which permits discharge of the particles remaining in the tank but prevents escape of the spheres or beads. Materials treated include phosphate or potassium ores and powdered plastic resins. Reference has been directed by the Comptroller to Specifications 1,025,688.

Title: Improvements in the production of polymer dispersions
IPC: C08F265/04
Filed: 1970-05-06
Abstract: 1294645 Making non-aqueous polymer dispersions CELANESE COATINGS CO 6 May 1970 [4 June 1969] 21762/70 Heading C3P Non-aqueous dispersion of polymers of one or more ethylenically unsaturated monomers are produced by a process in which the monomer or monomers are polymerized whilst dispersed in an inert liquid hydrocarbon medium boiling at from 100‹ to 500‹ F. and capable of dissolving not more than 10% by weight of the polymer being formed, in the presence of a tertiary alkyl peroctoate as initiator, and a polymeric stabilizer soluble in said medium, in an amount of 1-3% by wt. based on the combined weight of said polymer and stabilizer, the stabilizer being a homopolymer of an ester of acrylic or methacrylic acid with an alcohol of 8 to 18 carbon atoms, or a copolymer thereof with one or more other monomers, which has a Gardner- Holdt viscosity at 25‹ C. and 50% solids in V, M, and P naphtha, of at least C.

Patent GB-943375-A (GB)
Title: Improvements in or relating to the preparation of fleeces and non-woven fabrics
IPC: D04H1/50
Filed: 1962-06-06
Abstract: A non-woven fabric is formed from a mixture of natural or man-made textile fibres and cellulose ether fibres, the latter acting as a binder and having an etherification number, i.e. the number of substituents per anhydroglucose-unit, such that the fibres are soluble in alkali but insoluble in water, and are preferably swellable in cold water.  The natural or man-made fibres include animal or vegetable fibres, regenerated cellulose i.e. viscose or cuprammonium rayon, polyacrylonitrile or a mixture thereof.  The cellulose ether may be hydroxyethyl, carboxymethyl, methyl or carboxymethyl-hydroxyethyl cellulose.  Suitable fibres may be prepared by spinning solutions comprising 70% standard viscose and 30% of a 10% solution of hydroxyethyl cellulose. Carboxymethyl cellulose fibres which have been stored may be treated with a weak soda solution to restore their swellability which may have decreased due to internal lactone formation.  The cellulose ether fibres unite with the other fibres in the mixing stage and the resulting fibrous fleece is wetted with water and then dried.  The water may contain a swelling-reducing agent e.g. formaldehyde, glyoxylic acid or glyoxal, if desired in the form of primary condensates with melamine, urea or ethylene urea.  A catalyst e.g. ammonium nitrate or a mixture of magnesium chloride and sodium monophosphate may be added to the wetting solution. Alternatively, the fleece may be formed by combining cut fibres of short staple length on a paper-machine and consolidating.

Title: Improvements in the preheating of the initial materials in the destructive hydrogenation of bituminous coal
IPC: C10G1/06
Filed: 1938-07-25
Abstract: <PICT:0495954/III/1> <PICT:0495954/III/2> In the destructive hydrogenation of coal-oil pastes containing more than 45 per cent coal, disturbances in the usual tubular preheater are avoided by preheating the paste containing more than 45 per cent coal from 250 to 350 DEG  C. by admixture with hotter liquid reaction participants containing less than 45 per cent coal.  The participants may be fresh coal-oil paste or products obtained in the process and recycled for further treatment.  The preheating below 250 DEG  C. and above 350 DEG  C. may be carried out in the usual tubular preheaters.  The recycled constituents may be heated to the required temperature by addition of highly heated hydrogen.  Pastes having coal concentrations of 50 to 65 per cent may be used.  As shown in Fig. 1, a coal-oil paste containing 55 per cent coal is preheated by admixture with a paste containing 43 per cent coal which, together with 0,5 per cent tin oxalate and hydrogen, has been heated up to 450 DEG  C. in heat-exchangers b, c.  The mixture is further heated in the tubular preheater d from 360 to 420 DEG  C. and then passed through reactors e, f, g, the products passing into a catchpot h from which hot vapours are fed through the heat-exchangers b, c.  As shown in Fig. 3, the rich paste is first preheated with hydrogen to 250 DEG C. in a preheater d and is then mixed in a large mixing vessel e with hydrogen and recycle stock heated in a heater q, the mixture being heated to reaction temperature in a preheater f and passed into the reactor i.

Title: Improvements in the feeding of wire or other continuous filamentary material, particularly the feeding of wire for fuse-setting on guns
Inventor: KAY JAMES ARTHUR
IPC: F42C17/04
Filed: 1944-11-08
Abstract: 739,040. Ordnance; fuze setting devices. ROSE BROS. (GAINSBOROUGH), Ltd. Dec. 7, 1945 Nov. 8, 1944], No. 21977/44. Class 92(2). A fuze-setting device attached to the barrel 11 of a gun comprises two wire gripper units 36 which stretch a wire 81 across the muzzle so that a highvoltage can be applied to the wire for the purpose of manipulating the fuze of a projectile as it leaves the muzzle. The gripper units 36 are rotatably mounted and diametrically arranged on a carrier 21, 21, which is itself rotatable within a casing 16, 17, 14 about a supporting member 11. The carrier 21, 22 is driven intermittently by a continually rotating electric motor 32 through gearing 23, 24, whenever a clutch 29 is engaged. The clutch mechanism is similar to that described in detail in Specification 602,829, [Group XXIV]. When no wire extends between the gripper units to complete an electric circuit, a solenoid 101 is so energized that the clutch 29 engages and the carrier 21, 22 moves through 180 degrees before the clutch is disengaged. Each gripper unit is mounted on a ball race 60 and comprises semi-circular jaws 41, 42 which are caused to grip a wire 81 at the correct times bv the movement of a roller 57 engaging a track 58. The wire is fed from a rotatable reel 82 through a pivoted cover member 86. When the gun is fired the recoil motion actuates a changeover switch to apply a high voltage to the wire 81 and subsequently to restore the low-tension supply to the solenoid. The projectile breaks the wire and the blast forces the free ends against cutters 73. During rotation of the carrier a friction roller 43 engages tracks 76, 77 thereby oscillating the gripper unit approaching the feeder 83 so that it discharges any remaining wire fragment. Insulators 122 prevent flashover.

Title: Improvements relating to processes for the evaporation or distillation of sea water,brackish waters and like aqueous solutions
Inventor: ABRAMS HILTON JOHN
IPC: C02F1/46
Filed: 1957-07-11
Abstract: <PICT:0822990/III/1> A process for the evaporation of sea water, estuarine water and aqueous solutions in which the formation of calcium carbonate and magnesium hydroxide containing scales is reduced or prevented by adjustment of the hydrogen ion concentration of the solution prior to or during evaporation comprises adding to the solution hydrogen ions which have been generated in the anode compartment of an electric cell operating in conjunction with the evaporator from a solution containing a sufficient concentration of ions such as sulphate, nitrate, or phosphate ions to result in principally hydroxyl ions being discharged at the anode of the cell with the liberation of oxygen and/or in the promotion of an oxidation reaction at the anode with the consequent generation of hydrogen ions.  The cell preferably has 3 compartments and electrodes made from magnetite or platinum or graphite.  Preferably the feed is pretreated with steam to remove air and carbon dioxide.  In a preferred form of the invention, the solution of sodium chloride from which the magnesium and other metals having insoluble hydroxides have been precipitated by prior mixing with catholyte liquor is passed slowly through a centre compartment 21 from inlet 11 to outlet 14, a dilute solution of sulphuric acid being placed in the anode compartment 20 and oxygen being allowed to escape through line 13. Wash water is introduced into the cathode compartment 22 through line 12 and hydrogen and dilute caustic soda are removed through outlet 15.  On passing a current, hydroxyl ions are discharged at the anode and hydrogen ions accumulate in the compartment 20.  The current is carried across the membrane 5 by the migration of hydrogen ions into the centre compartment 21.  At membrane 6 current is carried predominantly by the migration of sodium ions to the cathode compartment 22.  In the central compartment there is a net gain in hydrogen ions.
