Patent GB-1037419-A (GB)
Title: Method and apparatus for contacting solids with gases or vapours
Inventor: HAYTER ALAN JOHN
IPC: B01D53/06
Filed: 1962-06-14
Abstract: 1,037,419. Heating, cooling or drying granular solids. PENNSALT Ltd. June 14, 1963 [June 14, 1962], No. 22939/62. Headings F4G and F4U. [Also in Division B1] A method of contacting solids with a gas or vapour comprises feeding the solids on to the uppermost of a plurality of horizontal screens in a screen unit, vibrating the screen unit as a whole simultaneously both with a vertical and an orbital horizontal movement, passing gas or vapour into the screen unit and through the screens and withdrawing it from the screen unit, and leading solids discharged from the edge of one screen to the surface of another screen in the screen unit and discharging solids finally from the screen unit. In Fig. 1, a platform 1 is mounted by a flexible rugged spring connection 2 on a rigid base 3. The motor 4 has two eccentric weights 6 and 7 which cause orbital horizontal and vertical vibration respectively of the screen unit 5. The screen unit 5 has screens 8, gas inlet 9, solids inlet 10, a gas outlet 11 and a valved solids outlet 12. The screen cloth is held tight by tensioning device 14 whilst a fan for the inlet or outlet or both may be used. Batchwise operation may be carried out by having a gate on the solids outlet. Gas may also be blown in through the solids outlet or inlet whilst the outlets 15 may be of valved construction. The size of the mesh screen may be such that all or some of the solids fall through it, their residence time being governed by the motion of the screens. The apparatus may include means for heating cooling, drying or otherwise treating the gas or vapour prior to entry into the screen unit. Various gases or vapours may be used, e.g. air, O 2 , N 2 , CO 2  or H 2 , and may be recycled to avoid waste. Thus in an embodiment (Fig. 2, not shown) the effluent gas passes through a dust collector which may then be fed back to the screen unit whilst the gas may be regenerated, e.g. by means of a heat exchanger, condenser or absorption bed, and then returned to the inlet of the screen unit. A combination of two screen units may be used, one to impart the desired property to a solid and the second to restore the gas to its original state before re-entry to the first screen unit. Solids which are contacted with gases or vapours according to the method of the invention, may undergo chemical reaction, heat exchange, drying or moistening, recovery of residual solvents contained therein; or may absorb gases or vapours, or a combination of any of these together with simultaneous classification of the solids. Moist gas or vapour may be dehumidified by contacting with a dry solid, e.g. alumina or the solid may be used to absorb gases or vapours.

Filed: 1957-07-19
Abstract: 859,853. Aerials. WOLSEY ELECTRONICS Ltd., [formerly WOLSEY TELEVISION Ltd.]. May 28, 1958 [July 19, 1957], No. 22946/57. Class 40(7). A dual band high frequency aerial comprises two V-shaped elements connected together at one of their ends by an impedance and at the other by feeder means, together with matching means if necessary, to form a rhombic aerial. The apices of the elements are spaced a half wave-length at a frequency in the lower frequency band and the spacing between the connections is greater than a quarter wave-length at this frequency. The aerial acts as a folded dipole at the lower frequency and as a rhombic aerial in the higher frequency band, where it exhibits a wide band-width. The aerial is slightly directional in the plane containing the elements but reflectors and directors may be added, and these may form part of the feeder junction unit and impedance unit.
Patent GB-1063098-A (GB)
Title: Improvements in heat exchangers
IPC: F28F3/08
Filed: 1964-06-03
Abstract: A hollow heat exchanger element having two opposed parallel walls and a plurality of integrally formed tubular elements 13 extending between said walls, (see Division F4), is made by an electro-forming process.  Firstly a matrix 32, e.g. as in Fig. 14, is made in the shape of the interior of the element and is produced from a low melting <PICT:1063098/C6-C7/1> <PICT:1063098/C6-C7/2> point metal alloy.  The matrix may be produced by gravity or die casting. Alternatively the matrices may be produced from paraffin wax or a synthetic resin mixed with a conductive material such as graphite or coated with a conductive layer of either a metal or graphite applied as a suspension in an organic solvent.  A matrix formed of a non-conductive material may also be provided with a conductive layer, e.g. a metal.  The matrix is in any case coated with a layer of graphite deposited from an organic solvent dispersion as a release layer for the electro-deposits.  The matrix is then subjected to an electro-forming process, an example comprising applying successive thin coatings of nickel, copper, nickel.  The nickel may be deposited from a Watts bath and the copper plated from a pyrophosphate bath containing also oxalate and nitrate.  When the electro-forming is complete the matrix is melted or evaporated out leaving a thin-walled box-type shell from which any residues are removed by chemical cleaning. In the element of Fig. 9 the strengthening 31 may be formed by the electro-forming or inserted afterwards.

Title: Improvements in or relating to the manufacture of sponge rubber
IPC: C08J9/30
Filed: 1947-08-20
Abstract: Sponge rubber is made by gelling and vulcanizing frothed latices which contain 0.5-5 per cent, based on the rubber content, of solid aliphatic hydrocarbons of m.p. 42-60 DEG C. derived from petroleum, the hydrocarbon being preferably emulsified, e.g. in aqueous potassium oleate solution, for adding to the latex.  The latex employed may be natural rubber latex or a synthetic rubber latex, e.g. a dispersion of polychloroprene or of a butadiene-styrene or butadiene-acrylonitrile copolymer, or a mixture of natural and synthetic rubber latex, and may contain a stabilizing agent exemplified by ammonia alkali hydroxide, potassium oleate, a rosin soap, sodium stearate, potassium lauryl sulphate, a sulphonated hydrocarbon, a sodium alkyl naphthalene sulphate, and a thickening agent exemplified by casein, gum tragacanth, waterglass.  Castor oil, which improves the elastic properties of the sponge rubber, and carbon black as a loading agent, and magnesium oxide or calcium silicate as a stiffening agent, for the sponge rubber may be incorporated.  Gelling agents specified are sodium fluorosilicate or silicofluoride, ammonium sulphate, ammonium nitrate, calcium sulphate, and 2-nitro-2-methyl-1-propanol.  Examples of antioxidants for rubber which may be incorporated are phenyl-B-naphthylamine, di-B-naphthyl-p-phenylenediamine, and the heptyl-diphenylamines, and of vulcanization accelerators, zinc mercaptobenzothiazole, benzo-thiazyl disulphide, zinc diethyldithiocarbonate, and tetramethylthiuram disulphide.  The Specification as open to inspection under Sect. 91 comprises also compounding the latex with 0.5-5 per cent of any paraffin or wax, e.g. of m.p. 90 DEG -750 DEG F.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in power assisted controls
Inventor: GARSIDE SAMUEL HENRY EDWARD
IPC: F15B21/10
Filed: 1949-09-07
Abstract: 694,358. Controlling aircraft. ROE CAXADA, Ltd.. A. V. Sept. 7, 1950. [Sept. 7, 1949] No. 23142/49. Class 4. [Also in Group XXIX] A servomotor control system, e.g. for operating aircraft control surfaces, comprises a booster mechanism disposed in series between a driving member and a driven member and actuated by relative movement therebetween and a damping device connected in parallel with the booster mechanism and constituting a linkage between the driving and driven members such that rapid movements originating in either one of the members is transmitted directly to the other to by-pass the booster mechanism. As shown for operating the ailerons, a booster mechanism comprising a hydraulic jack 25, Fig. 2, and a control valve 23 therefor is disposed in series between a driving lever 15 connected by a rod 13 to the pilot's control and a driven lever 19 connected by rods 11 to the ailerons. The levers 15, 19 are pivoted on a fixed fulcrum 16 and movable relative to each other through a pin and hole connection 20, 21, the lever 19 being connected to the jack cylinder and the lever 15 to the movable member of the valve, the valve housing and the cylinder being integral with each other. The jack piston is anchored to one end of a lever 26 mounted on a fixed fulcrum 27 and connected at its opposite end by a link 28 to the lever 15 to provide "feel" to the pilot's control. A spring-loaded pawl 43 urged by fluid pressure anchors the piston rod to a release unit 29 trunnioned to the lever 26, which, on failure of fluid pressure in the system, releases the rod to permit of manual operation of the ailerons. A dashpot 30 connected between the levers 15, 19 and in parallel with the booster mechanism comprises a casing 33, Fig. 3, housing a loosely fitting plunger 39 having guide shafts 40, 41. On slow application of load by the pilot the dashpot allows relative movement between the levers 15, 19 through the pin and hole 20, 21 and the booster mechanism to operate the ailerons. On rapid application of load, either by the pilot or due to aerodynamic loads acting on the ailerons, the dashpot acts as a rigid member to transmit the load between the levers to by-pass the booster mechanism and so prevent "hunting" of the valve.

Title: Improvements in or relating to a process for finishing natural and regenerated cellulose fabrics
IPC: D06Q1/08
Filed: 1948-09-02
Abstract: Fabrics of cellulose and regenerated cellulose and mixtures thereof are impregnated with a 5 to 20 per cent by weight aqueous solution of water-soluble, acid-catalyzable, thermo-setting resin-forming materials, water-insoluble after hardening, containing a minor amount of an acidic or potentially acidic catalyst, the solution pick-up being 70 to 90 by weight on the dry fabric, then dried until substantially devoid of free moisture, cooled to room temperature, passed through a mechanical finishing pressure calender at a temperature such that the fabric is heated to a temperature between 100 DEG  and 200 DEG  F. and preferably below 175 DEG  F. and then cured in an atmosphere of from 250 DEG  to 350 DEG  F. for 8 to 2 minutes.  Suitable resin-precondensates include melamine-formaldehyde, urea-formaldehyde, thiourea-formaldehyde, dicyandiamide-formaldehyde and mixtures thereof.  Glyoxal may be substituted for formaldehyde.  It is important that no polymerization of the resin-forming materials should occur during the mechanical finishing.  The catalyst may constitute 3-5 per cent by weight of the solid resin-forming materials, and it is preferred that it should have a pH on the dried fabric at a temperature of about 212 DEG  F. of 6 to 8, but develop high acidity at higher temperatures.  Ammonium hydroxide may be added to the impregnating solution to maintain neutrality during the drying. Suitable catalysts are carbazide hydrochloride, phenyl biguanide hydrochloride, monoguanyl urea phosphate, dimonoethanolamine hydrogen phosphate, and octadecyloxymethyl pyridinium chloride. The impregnating bath may contain a cation-active permanent softener such as octadecyloxymethyl pyridinium chloride when treating cotton materials or a water-removable softener such as carbowax when treating regenerated cellulose materials.  The preferred amount of softener is from 1 to 4 per cent by weight of solution.  Any mechanical finishing treatment may be applied to the fabric.  In an example a cotton fabric is impregnated with a solution comprising 40 lbs. of melamine-formaldehyde precondensate (80 per cent solids), 20 lbs. urea-formaldehyde precondensate (50 per cent solids), 10 lbs. softener, 4 lbs. monoguanyl urea phosphate, 1 lb. of 28 per cent ammonium hydroxide and water to make 100 U.S. gallons.  The impregnated fabric is squeezed to give a solution pick-up of 70 per cent and dried at 350 DEG  F. until approximately 6 per cent moisture (natural) remained therein and quickly cooled to 65 DEG  F.  It is then chase-calendered in a five-bowl calender, the steel bowls of which are heated to 250 DEG  F. After curing for 2 minutes at 350 DEG F. it is washed and dried. Specification 672,674 is referred to.

Filed: 1974-05-23
Abstract: 1440151 Packaging; shrinkable capsules MOLECULON RESEARCH CORP 23 May 1974 [23 May 1973] 23163/74 Headings B8C and B8T [Also in Divisions B5 and B2] Films prepared from cellulose triacetate gels are used as packaging materials. They may be wrapped around electrical parts, or bolts, twist-sealed and then allowed to dry, thus causing the film to shrink and conform to the shape of the article packaged. If cup-shaped films are prepared, these may be placed over bottles and, when shrunk, form good seals. If the liquid in the gel is replaced by glycerine and the surface of the film coated with a pressure sensitive adhesive the product can be used as a pressure sensitive seal for boxes &c. Light pressure causes adhesion, firm pressure forces the glycerine from the gel and breaks the seal. Release of this pressure is accompanied by readsorption of the glycerine and the seal may be reformed.

[Class 83 (iv)]  A ring rolling-mill for forming and finishing bearing races &c. comprises a pair of horizontal shafts, having vertically disposed faces formed to engage the sides of a blank, mechanism for reciprocating one of said shafts horizontally to and from blank-engaging position, a mandrel rigidly borne by one shaft, the other shaft having a mandrel-receiving recess formed in it, and means for pressing a horizontal work roll against the periphery of the blank to roll the blank between said roll and said mandrel. The tubular, water-cooled shafts 13, 14, are'driven by the double-ended motor 48, through belting 49, 51. Shaft 14 carries the mandrel 22, and shaft 13, having a recess 23, is reciprocated together with its housing 17 and pulley 54, by a piston-rod 42,. the stroke of which is adjusted for blanks of varying widths by a set-screw on the sliding member 25, which screw abuts on the stationary part of the frame, Figs. 7 and 8 (not shown). The driving pulley 52 is constrained to move longitudinally of the motor shaft to maintain alignment with the pulley 54 by means of a linkage comprising an arm 63 fixed to the pistonrod 42, rock-shaft 57 and arm 64. The work roll 24 and the motor-driven backing rolls 103, are carried by a bracket 81, pivotally mounted on a rod 82 and rocked thereabout by means of a piston-rod 91, the downward swing of the bracket being limited by an adjustable stop 98. The roll 24 is directly supported by a spring- loaded member 113, and an auxiliary supporting member 118, which latter may be removed to enable a different size work roll to be substituted. A guide roll 122, Fig. 2, is secured to the bracket 81 and maintains contact with the periphery of the blank to prevent distortion, being mounted on a spring-loaded arm 124 secured to the main frame by a link 126, and at the upper end to a bell-crank 129. A follower 131 rides on a cam surface 132 carried by stationary side-plates, so that as the bracket 81 swings downwardly to reduce the pass, the guide-roll 122 maintains the blank in circular form. A loading arm 139, operated through links by a. solenoid 136, positions blanks in alignment with the mandrel 22. Shaft 13 is mounted with a slight upward tilt from the horizontal axis of the shaft 14, Fig. 6, so that the blank is engaged on both sides by the working faces of heads 19, 21, only when the related portion of the blank is being rolled between the roll 24 and the mandrel 22.

Filed: 1919-09-23
Abstract: 166,262. Saunderson, H. P. Sept. 23, 1919. Ploughs.-A multiple furrow plough for haulage by mechanical tractor or other power is supported on land and furrow wheels f, e, and a rear wheel f<0>. The land-wheel f is carried on a cranked axle f<1> to which is attached a bracket g supporting a shaft g<1> carrying a crank-disc j. The shaft g<1> also carries a loose sprocket-wheel h<2> driven by chain from a sprocket-wheel h on the wheel f and adapted to be clutched to the shaft g<1> by pulling a cord i<5> attached to a clutch lever i. The crank-pin of the disc is connected by a rod j<2> to a lever j<3> pivoted on the main frame and adapted to be adjusted along a quadrant j' to vary the depth of working. As the shaft g<1> rotates, moving the crank-pin, the bracket g and cranked axle f<1> are swung about the axis of the latter thus raising or lowering the ploughs. To lock the ploughs in the raised or the lowered position and to ensure that the shaft g' remains clutched to the wheel h<2> for a full half-revolution, the lever i is connected to a crank-pin l which is adapted to enter into one or other of two recesses k, k<1> situated opposite to each other in the disc j. When the pin l is in either of these recesses the clutch is freed and the disc is locked against rotation. Whilst the pin l is riding on the edge of the disc the clutch is kept thrown in even though the cord i<5> is released. To operate the furrow wheel simultaneously with the land. wheel a rod m connects the bracket g with an extension of a racked quadrant n adapted to be adjustably locked, to a shaft n<1> mounted in the plough frame and carrying an arm n' slotted to engage a pin o on the sliding vertical support p of the wheel e. The plough is provided with a draw-bar r pivoted at r', which on being deflected to either. side causes deflection of the wheels e and f<o> as described in Specification 166,496, arms on the vertical supports of these wheels being connected by a rod v, and the support p of the wheel e also carrying an arm s connected to the draw-bar r.
