Title: Improvements in devices for operating on live wires
Inventor: CROSS ERIC VICTOR
IPC: H01B13/26
Filed: 1968-02-22
Abstract: 1,247,863. Clamps. MIDLANDS ELECTRICITY BOARD. 11 Feb., 1969 [22 Feb., 1968], No. 8550/68. Heading B4W. [Also in Division B8] A tool, which may carry a reel 18 of tape 19 for application to an electric cable 11, has a fixed jaw 10 and a jaw 12 movable by a screw 13 to clamp the wire between the jaws, and has two parallel blades (not shown) mounted in one jaw to engage the wire at an angle to its axis, so that by rotating the tool about the axis of the wire, it is caused to move along the wire. The tape is thus wrapped helically about the cable.
Patent GB-576394-A (GB)
Title: Improvements in or relating to the formation of layers of organic polysulphide polymer plastics
IPC: C08L81/04
Filed: 1944-05-06
Abstract: To an aqueous suspension of particles of organic polysulphide polymer plastic, is added 0.03 to 1.0 part by weight of hydrogen sulphide per 100 parts of suspended solids, in the form of a solution of hydrogen sulphide in ammonia of such a strength that the molar ratio of added hydrogen sulphide to ammonia in the suspension after the addition is not less than 0.75 : 1, and a layer of particles is directly deposited from the suspension, e.g. by spreading or spraying the suspension on to a fabric or other backing and drying or by dipping a former into the suspension and drying.  The layers of plastic thus formed are crack-free and fabric coated with the layer may be used for liquid hydrocarbon fuel tanks.  The solution to be added to the suspension is prepared by saturating with hydrogen sulphide a 0.5-5 per cent aqueous solution of ammonia.  Commercial ammonium sulphide solution contains too little H2S and should be diluted and then saturated with H2S to be suitable.  The suspension is preferably allowed to stand after the addition before use, e.g. for 5 minutes at 140 DEG  F. for 15 minutes at 100 DEG  F. or for 30 minutes at room temperature.  It is stated that an improvement similar to that obtained by the present invention may be obtained by bubbling H2S through the suspension, but this is undesirable from a commercial point of view.  Specifications 302,270, [Class 2 (iii)], and 359,000 are referred to.
Patent GB-1500990-A (GB)
Title: Separation of non-magnetic conductive metals
IPC: B03C1/23
Filed: 1975-02-28
Abstract: 1500990 Magnetic separation OCCIDENTAL PETROLEUM CORP 28 Feb 1975 [11 March 1974 (2)] 8628/75 Heading B2J Non-magnetic conductive (NC) metals such as aluminium and copper are separated from particulate mixtures containing such metals by passing a stream of such mixture in a first direction through the travelling magnetic field of the stator of a linear motor so orientated with respect to the first direction as to divert the NC metals from the path followed by the remainder of the stream components. As shown, a particulate mixture 22 is fed on to a conveyor belt 12 which passes over a linear motor 18, energised to produce a travelling magnetic field which laterally displaces a first fraction 24, mainly constituted by NC metals, on to a second belt 14. Components 33 other than NC metals in the fraction 24 are separated out by the action of a second linear motor 20 over which the belt 14 passes, so that the final fraction 35 which is diverted on to a third belt 16 consists almost entirely of NC metals. The belts may be vibrated to aid segregation of the various components. In a second embodiment, a single conveyor belt is associated with two linear motor stators and with guides for the separated fractions (Fig. 3, not shown).

Title: Manufacture of tiles and the like
IPC: B28B19/00
Filed: 1936-03-26
Abstract: A wall or floor tile, slab or like article having a mottled or network appearance is produced by covering the surface to be faced, with pellets or nodules made of cementitious material and of different colours or shades or applying sufficient pressure to deform the pellets so that they present a plane surface, and, after hardening, removing the outer surface, e.g. by grinding, to expose the interiors of the pellets.  The pellets may be made of plaster but are preferably made of a mixture of cement and sand; they may be coated with a skin of a different colour by rolling them, while plastic, in a dry cement powder or by dusting them with the powder. The pellets may be placed in the bottom of a mould which is filled up with a cement mix to a depth in excess of the thickness of tile required, the mould is then subjected to pressure, the tile is removed and allowed to stand for twenty-four hours, and is cured, by immersion in water, before grinding.  The pellets may be made by feeding the cement and sand mixture into an inclined tube-mill with a controlled speed, and passing the pellets over screens as they leave the mill.  Pellets of a larger or smaller size are returned to the mixer.

Title: Improvements in wireless signalling systems for controlling tuned electro-mechanical relays
IPC: H04B1/16
Filed: 1931-03-25
Abstract: 371,565. Wireless signalling. RICCHIARDI, P. C., 1, Via Montecuccoli, Turin, Italy. March 25, 1931, No. 9126. Convention date, March 31, 1930. [Class 40 (v).] A number of radio receiving-stations are provided each with a series of tuned mechanical vibrators 13 adapted for selective operation by incoming signals, the incoming wave being first rectified by a detector 3 to bring out a modulation sub-wave in the circuit 4, and the sub-wave being heterodyned by a local oscillator 6. The resulting beat frequency appears in the plate circuit of a second detector 9 and after amplification by the valves 10, 11 acts on the relay 12 and selectively operates one of the vibrators 13; to close a selected circuit. As the local source 6 can be adjusted in frequency, the sets of tuned vibrators 13 may be identical at all the receiving-stations. The vibrators may operate either directly or through further relays to close a selected telephone circuit; or the system may be applied for telegraphic purposes, each signal being constituted by groups of two or more frequencies as in Specification 276,376, [Class 40 (v), Wireless signalling &c.].
Patent GB-565467-A (GB)
Title: Process for producing branched chain saturated hydrocarbons
IPC: C07C2/62
Filed: 1942-07-02
Abstract: <PICT:0565467/IV/1> Branched chain saturated hydrocarbons are prepared by reaction of isoparaffins with olefines in presence of an alkylating catalyst comprising hydrogen fluoride in a reaction zone, separating a stream of hydrocarbon reaction products from the used catalyst, returning a portion of the used catalyst to the reaction zone, fractionally distilling purified hydrogen fluoride from another portion of used catalyst from the reaction zone in a first recovery stage, separately recovering dissolved hydrogen fluoride from the separated hydrocarbon reaction products by fractional distillation in a second recovery stage, and returning hydrogen fluoride from each recovery stage to the reaction zone.  An example is given of the production of a high octane motor fuel from isobutane and butylenes and the process may also be applied to the alkylation of isopentane with propylene or pentenes.  As shown, the reaction takes place in vessel 9, an emulsion of hydrocarbons and HF is circulated through a cooler 12, and a portion of this emulsion is withdrawn to settler 17, the HF being returned to the reaction zone and the hydrocarbons passing to fractionators 24 and 40 where HF is recovered, the alkylate is withdrawn at valve 92, and isobutane is returned to the reaction zone by pipe 51.  Another portion of used catalyst is withdrawn to the settler 55 and dry HF is recovered by means of fractionators 60 and 72 and returned by line 88 to the reaction zone.

Title: Improvements in or relating to fluid-treatment apparatus
IPC: B01J47/02
Filed: 1954-03-30
Abstract: 761,159. Purifying liquids. ZWICKY, J. F. March 28, 1955 [March 30, 1954], No. 9279/64. Class 46. Liquid to be treated passes at 18 into " empty " cells 6 to 10 and cells 1 to 4 containing treatment material separated by micro-porous diaphragms 16 and emerges at 13 after passing through all the cells in series. In the regeneration phase air is admitted at 19 while liquid drains through upwardlyacting non-return valves 31 and 32 and drain valves 22, 23 and 34. Valves 22 and 23 are then closed and regenerating liquid, e.g. dilute hydrochloric acid, is admitted at 20, passes through, e.g. a strongacid cation-exchange material in cell 3, pipe 24 and similar material in cell 1, through a downwardlyacting non-return valve 26, a down-turned drain pipe 28 and 18 drain valve 34. Strong-base anion-exchange material in cells 4 and 2 is similarly regenerated with dilute sodium hydroxide solution. In this phase the cells 6 to 10 constitute air gaps bounding the treatment cells. It is stated that the invention may be applied to ion-exchange treatment for the purification of air containing droplets including metallic radicals. e.g. so-called " smog."
Patent GB-917197-A (GB)
Title: Improvements relating to closed loop television systems
Inventor: MILLBURN JOHN RICHARD
IPC: G01S13/86
Filed: 1960-03-16
Abstract: 917,197. Radar. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 16, 1961 [March 16, 1960], No. 9320/60. Class 40 (7). [Also in Group XL (b)] In an auto-follow radar system employing a closed loop television system comprising a television camera " seeing " through a sighting telescope mounted on the radar aerial and supplying video signals to a television picture reproducing tube at a stationary observation position, displacement of the target from the intersection of the telescope cross-wires (as seen in the reproduced picture) due to acceleration errors in the servo systems controlling the aerial movement (as distinct from noise errors) may be measured by producing a visual mark the rectangular co-ordinates of which are determined by the azimuth and elevation servo error voltages. Since the visual mark is displaced from the intersection of the crosswires, automatically, in accordance with acceleration errors, the remaining error, i.e. that causing displacement between the target and the visual mark is due to "noise." As shown in Fig. 1, the line synchronizing pulses are separated from the video signal input 1 from the television camera and supplied to a circuit 8 (described in detail in connection with Fig. 2, not shown), which produces output pulses delayed relative to the input pulses by an amount determined by the azimuth error signal input 9. These pulses are supplied to a coincidence circuit 13 together with pulses produced by a generator 10 when the voltage across resistor R in the frame scan circuit coincides with the elevation error signal input at 13. The output of circuit 13 then comprises a brightening pulse which is fed to the control electrode of the picture tube and reproduced at a position determined by the magnitude of the two servo error signals. To ensure that a brightening pulse always occurs on at least one line of each frame the duration of the pulses from generator 10 should be at least equal to that of two successive pulses from circuit 8. The generator 10 and circuit 8 are provided with a constant delay so that in the absence of error signals the brightening pulse coincides with the intersection of the telescope crosswires.

Title: Improvements in or relating to the production of concentrated aliphatic acids
Filed: 1932-04-01
Abstract: Aliphatic acids such as acetic, propionic, and butyric acids are concentrated by extracting with a solvent of low boiling-point together with an oxygen-containing liquid of boiling-point at least 150 DEG  C. in which water is insoluble, or extracting with a low-boiling solvent and precipitating water from the extract by adding the high-boiling oxygen-containing liquid.  The quantity of the low-boiling solvent is at least 50 per cent of the mixed solvents.  Suitable low-boiling solvents are ethers such as diethyl ether, esters such as ethyl acetate, and butyl formate, and methyl-ethyl ketone.  Suitable high-boiling liquids may be ketones, ethers or esters, Suitable ketones are acetophenone and other alkyl aryl ketones; suitable ethers are anisol, phenetol, benzyl phenyl ether, and the corresponding ethers of other phenols, naphthols or hydroxy compounds of the aromatic series (see Specification 354,198), and suitable esters are esters of mono-, di-, and polybasic acids or of mono-, di-, or polyhydric alcohols, such as amyl acetate, octyl acetate, butyl butyrate, benzyl acetate, dimethyl, diethyl and dibutyl phthalates, ethyl and benzyl benzoates, glycol dibenzoate, ethyl naphthenate, and other hydroaromatic acid esters.  Any water in the extract may be removed by a dehydrating agent such as sodium sulphate or as an p  azeotropic mixture with one of the components of the extracting medium, such as ethyl acetate, or with a suitable added substance; for instance when ether and anisol or phenetol are used for the extraction, the ether may be distilled off first, the remaining solution being then dehydrated by distillation with benzene or ethylene chloride.  Specifications 283,702 and 338,187, [both in Class 2(iii), Dyes &c.], also are referred to.  The Provisional Specification mentions isopropyl ether, ethyl butyrate, and acetone oils as solvents of low boiling-point, and describes the other component of the extraction medium as being preferably of boiling-point above 140 DEG  C.

Title: Improvements in and relating to apparatus for making and collecting sequins, buttons and the like
IPC: B21D53/48
Filed: 1945-04-17
Abstract: 587,820. Cutting-out presses. WEIL, A. April 17, 1945, No. 9607. [Class 31 (i)] [Also in Groups XVII and XXII] In an apparatus for making sequins, buttons, or other perforated discs, the discs are delivered from a machine, which cuts the discs from sheet stock and perforates them in a machine which delivers them into a collecting device which stacks the discs in axial alignment so as to enable a string to be threaded through the discs for transport or for stitching upon cards &c. The collecting device comprises one or a battery of tubes 4, 5 mounted between plates 8, 9 in staggered rows, the plates being connected by bolts and nuts. The tops of the tubes 4, 5 are tapered, and fit in apertures 10 in the die-plate 1 from which the finished discs emerge. An apertured stopper 12 is fitted tightly into the top of each tube at the start of operations, and this is pushed down the tube until it finally reaches the position in Fig. 2, when it may operate a signal device to warn the operator, and the stopper may be graduated to indicate the number of discs produced. In a modification adapted to render the threading of the discs automatic, the discs as they pass down the tubes 4, 5 slide over eyed wires or fine rods attached to a cylindrical stopper attached to the bottom of each tube, and the stoppers 12 also slide over the eyed wires. A fine wire or thread is attached to the eyes of the wires or rods.
