Abstract: 950,491. Arrangement of passenger tracks and lifts. GEO. H. GASCOIGNE CO. Ltd. Jan. 31, 1962 [Feb. 3, 1961], No. 4116/61. Heading A4T. [Also in Division B8] In a goods handling system including an inclined trackway along which loaded platforms move under gravity to a discharge point where they are successively removed by a fork lift truck, the tines E1 of the truck as they pass beneath the end trolley push against members A1 to move a longitudinally reciprocable bar B1 against the resistance of restoring springs C2. When the tines are withdrawn the bar automatically returns and pawls B2 thereon cause movement of at least the end one of the remaining platforms towards the discharge position. Preferably the bar B1 is guided by rollers B3 attached to the bar and running in a guideway C1. Either the platforms are wheeled and the trackway is rigid as shown, or the platforms are unwheeled and the rails F1 are replaced by rollerways.

Abstract: 439,268. Target toy. MILLER, D. J. G., 54, Blackburn Grove, Bootle, Lancashire. Feb. 11, 1935, No. 4270. [Class 132 (iii)] A target for projectiles comprises a disc 17 flexibly connected by a rubberized canvas disc 18 to the double pulley wheel 16 driven by the elastic 22 wound on to part 23 of the pulley by a cord 25 on part 26. The disc 17 has target figures 13 stuck radially or pivoted on the disc 17 to appear at an aperture 12 in the enclosing box. The disc 17 also has apertures 19 separated by spokes 20 which are engaged by a stop pawl 21 to allow intermittent rotation of the disc 17 when the figures 13 are hit by projectiles to cause displacement of the disc out of its normal plane and disengagement of the stop pawl. The number of times the target is struck is shown by numbers 31 on the disc 17 appearing at an aperture 30 in the box. The target may be positioned in the front wall of a collapsable fort 33, 34, with folding back wall 35 which forms a cover when collapsed. All the target figures may be pivoted on the disc and may appear at extra openings 37. To allow in this modification for release and rotation of the disc when any of the figures is hit, the disc may be mounted to slide back on a number of pins attached to the pulley 16 parallel to its spindle, a spring being provided to return the disc. The pulley spindle 14 is carried on a plate 15 secured to the front cover. A long elastic rove over several pulleys may be used to even out the driving tension. Rotation of the target may be arranged to ring a bell and instead of appearing at an opening the targets may appear over a wall. A stop may be fitted on the back of the box to limit the flexing of the target disc.

Title: Improvements in or relating to the coiler mechanism of carding engines, combing machines and other textile machinery
IPC: B65H54/80
Filed: 1942-04-01
Abstract: 554,357. Coilers for carding engines &c. FINE COTTON SPINNERS & DOUBLERS' ASSOCIATION, Ltd., and ROSE, W. E. April 1, 1942, No. 4328. [Class 120 (iii)] Coiling mechanism for carding engines &c. is arranged to take cans of increased diameter by moving the vertical axis of the can relative to the vertical axis of the coiler plate in a direction to allow a can of increased diameter to be accommodated and by increasing the distance of the inner guiding edge of the coiler tube from the axis of the coiler plate; the coils formed in the can are thus overlapped with the formation of the usual central vertical hole in the sliver mass. As shown the can support plate A and its support A<SP>1</SP> are moved a distance from the vertical shaft F equal to half the difference in the diameters of the original and larger cans by the provision of slots in the support and carrier wheels are introduced in the train of gears f between the shaft F and the gear a on the plate A; gears are also introduced between the shaft F and the gear c on the coiler plate C or the shaft F may be tilted slightly toward the coiler plate and carry a smaller gear engaging the gear c. The distance between the inner edge of the coiler tube D and the axis of the plate C is increased by inserting a lip D<SP>1</SP> in the tube; alternatively, a tapered tube may be inserted in the tube D, or a tube inclined at a more acute angle to the top of the coiler plate may be substituted for the tube D, or a casting having such a tube may be secured to the top of the coiler plate, or a new coiler plate with a suitable tube may be provided.

Title: Improvements in one-way driving mechanism
IPC: F16D41/28
Filed: 1925-02-17
Abstract: 246,677. Garvie, D. Feb. 17, 1925. Clutches, free-wheel. - In ratchet gearing and freewheel clutches of the kind set forth in Specification 240,685, the ball bearings 12, Fig. 2, for the sprocketring 2 are transferred to the inner periphery of the side plates 5, 10, one of which may be made integral with the ring 2, the other being screwed thereto and locked in adjusted position by one or more grub-screws 13, which press on the central flange 3 of the ring 2. This method of locking the ring 10 dispenses with the need for packing-pieces. Bearing races are formed in the parts 5, 10 and in the angles of the T-shaped inner ring 8. The abutment surface 17, with which the clutch ball &c. 14 engages during forward drive, may be of any of the shapes described in the above-mentioned prior Specification, but is formed on an independent block 16 Fig. 3, inserted axially in a slot in the flange 9 of the ring 8, so that the lateral thrust due to jamming is taken directly by one of the side plates 5, 10 and the necessity for a special aperture for inserting the ball &c. 14 during assembly is obviated. Where the sinuous cam or groove 4 acts radially, it is formed on the inside lateral face of the integral side plate 5.

Title: Process and apparatus for the formation of channels in sheets of cardboard, corrugated cardboard or the like
IPC: B31B50/25
Filed: 1934-02-09
Abstract: 425,506. Creasing cardboard &c. AKT.-GES. FUR CARTONNAGENINDUSTRIE, Industriegelande, Eingang G., Dresden, Germany. Feb. 9, 1934, No. 4375. Convention date, Feb. 18, 1933. [Class 100 (ii)] [See also Groups VII and VIII] A process for forming two parallel channels in a sheet of cardboard or the like is characterized in that, on passing through the machine, the longitudinal edges of the sheet are displaced towards its longitudinal centre line, and the transverse arching so formed is then flattened to produce the inner walls of the channels, whilst the channels are completed by displacing the longitudinal edges of the sheet towards the position of the channels. The feed rollers 1, 1<1>, Fig. 3, are set in planes converging in the direction of motion towards the centre line of the sheet 3 in order to produce the transverse arching X, which is flattened between rollers 2, 2<1>, Fig. 4, the inner walls of the channels being shaped by stationary blades 8 and rings 5 projecting from the rollers 2<1>. The free edges of the sheet are then pressed against the outer side of the rings 5 and rollers 2<1> by obliquely mounted discs 10 of ridge-shaped peripheral cross-section to complete the channels. The rings 5 may turn freely in grooves in the rollers 2<1>, and are supported by rollers 15, at least one of which is adjustable up and down to vary the projection of the ring 5 above the roller 21, so varying the depth of the channels produced. The feed rollers 1, 11 and the rollers 2, 21 are positively driven, but the discs 10 are mounted idly. All the members serving to form the channels in the cardboard are adjustable so as to be caused to converge, or diverge, to vary the spacing of the channels in the cardboard.

Title: Improvements in spring suspension devices for piping systems
IPC: F16L3/205
Filed: 1943-03-18
Abstract: 565,189. Resilient supports. GENERAL SPRING CORPORATION. March 18, 1943, No. 4392. Convention date, Nov. 26, 1942. [Class 99 (ii)] [Also in Group XXXII] A spring suspension system for pipes, particularly steam piping, subject to both thermal expansion and vibration, comprises a hanger including a spring system which has a load deflection characteristic, Fig. 4, which changes sharply at a point C corresponding to the normal operating position, thus rendering the system non-harmonic. In one form, a rod 38 pivoted from a support 88 is connected to a piston 16 working in an oil-filled cylinder 2 connected by a bolt 12 to the piping. The load is supported by a main spring 50 located between an adjustable cylinder end 52 and the piston. An auxiliary spring. 58 is located between an adjustable upper gland member 56 and an extension on the back of the piston and the parts are so arranged that in the' normal position of the load the auxiliary spring is not compressed. Thus, if vibration occurs, a decrease of the load will give a corresponding deflection corresponding to the characteristic A of the main spring, Fig. 4, whereas an increase of the load will stress the auxiliary spring and give a deflection corresponding to the steeper line B, thus avoiding the possibility of harmonic vibration. In normal movements of the piping, oil can flow from one side to the other of the piston through holes 34 in spring flap valves 30 covering orifices 28, but if excessive shock, as by a collision in a ship or an earthquake, occurs, the valves are opened to allow the necessary rapid transfer of fluid. In a modification, the orifices are covered by perforated diaphragms which may be broken by any sudden shock. The piston-rod 38 which may be tubular to facilitate assembly may be marked to indicate the adjustment of the screwed member 56 above the auxiliary spring. Specification 535,823 is referred to.

Abstract: 575,238. Protective cut-out systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 9, 1944, No. 4431. Convention date, March 9, 1943. [Class 38 (v)] To prevent damage to a power capacitor on the breakdown of one of its component capacitors, a protective system is provided by connecting reactance coils X1, X2 &c. in parallel with the partial capacitors C1, C2 &c., the values of these coils being such that the voltages at the terminals of corresponding capacitors and reactors are equal. The currents in the interconnectors are normally negligible and only increase if any of the capacitors is short-circuited. This increase is used to operate a relay R by means of current transformer T, thereby opening switch B and isolating the power capacitor. When it is necessary to make three-phase star-or delta-connections, Fig. 7, three reactance coils XI, XII, XIII arranged on a common core are used in conjunction with current transformers T1, T2, T3 which are connected in series with relay R,

Title: Vehicle suspension system
IPC: B60G17/015
Filed: 1963-02-05
Abstract: 1,026,472. Pneumatic suspension systems. DUNLOP RUBBER CO. Feb. 5, 1963 [Feb. 9, 1962], No. 4584/63. Heading B7D. A pneumatic suspension system for the rear axle 7 of the tractor of a tractor and semitrailer combination includes escape valves 20, 20<SP>1</SP> which are operable pneumatically under the control of a lever 29 to enable the pressure in air springs 6 to be reduced prior to separation of the tractor from the semi-trailer, and are closed automatically after a predetermined interval during which separation is effected. A valve 25 normally connects an air feed pipe 26 with a reservoir 27 and a coupling head 28 for a trailer brake but upon actuation of the lever 29 the valve 25 connects the reservoir 27 with the escape valves 20, 20<SP>1</SP>. A piston 35 (Fig. 3) within each escape valve is displaced by the compressed air to unseat a valve 52 permitting air from the associated air spring 6 to lift a valve 42 and escape to atmosphere through a felt plug 48 and a perforated hood 49. A spring 44 is arranged to close the valve 42 when the air spring pressure is sufficiently reduced. A bleed orifice 36 uncovered by the piston 35 connects the reservoir 27 to atmosphere and after a predetermined interval the reservoir pressure drops sufficiently to permit a spring 54 to close the valve 52. In Fig. 4 (not shown), a further valve is pressurized simultaneously with the escape valves 20, 20<SP>1</SP> to cut off the air supply to levelling valves 12 which normally control the air spring pressure, and the pressure is relieved to restore the supply to the levelling valves immediately the semitrailer is separated from the tractor by a relief valve actuated upon release of a saddle normally depressed by engagement with the semitrailer.

Abstract: 1437651 Belt gearing GOODYEAR TIRE & RUBBER CO 31 Jan 1974 [1 March 1973] 04622/74 Heading F2Q A drive belt having inside and outside teeth 4, 16, not essentially of the same configuration and alignment, but accurately positioned with respect to each other, with an inextensible tension member 14 therebetween, is made by taking first and second portions 1, 15 of flexible polymeric material, toothed on one side only, positioning the toothed side of the first portion 1 around a toothed metal mandrel 8, helically winding a tensile cord 14 about the exposed plain side, positioning the plain side of the second portion 15 around the tensile cord 14, aligning and retaining the teeth 16 of the second portion 15 with the teeth 4 of the first 1, in a predetermined relative position and curing the assembly into a single moulded cylindrical structure from which individual belts are severed. Belt materials.-Each portion 1, 15 comprises a laminated sheet of unvulcanized neoprene and a wear-resistant outer layer 7 of rubber impregnated textile fabric such as nylon. The tensile layer 14 may be cotton, nylon, rayon, polyester, fibre glass or steel, coated with neoprene cement during winding. Process.-The inner portion, formed as two axially-spaced portions 1, is wrapped around the toothed mandrel 8, and its ends lap-spliced, using neoprene cement. After applying the tensile layer 14 helically on the plain surface of the inner portion 1, the outer portion 15, formed as two similar axially-spaced portions 20, 201, is wrapped around the tensile layer 14, with its plain inner surface treated with a solvent wash, and its ends are butt-spliced. Application of the outer portion 15 may be facilitated by the use of a steel or aluminium pressure roller 21 having teeth engaging the teeth 16 of the outer portion 15 and separate rings 24 of teeth at each end, of the same material as that of the roller, or of a reinforced vulcanized elastomer, meshing the teeth exposed at the ends of the mandrel 8, to ensure accurate alignment of the inner and outer teeth 4, 16 of the belt. Such alignment is then maintained during cure, by a surrounding cylindrical matrix 32, Fig. 11, of vulcanized synthetic rubber having internal teeth meshing those of the belt and inwardly projecting end and intermediate rings 34, 38 of teeth meshing the exposed end and central teeth of the mandrel 8. The matrix is formed of a number of segmental axial strips separately applied around the outer belt layer, and has two embedded strain resisting layers (40, 41) of textile fabric, fibre glass, or metal, with interposed steel strips. A method of making the matrix is described. After curing, the matrix and mandrel are removed and the cured belt sleeve placed on a cutting mandrel for severing the belts.

Abstract: 427,267. Paper treated with viscose; coating webs; compound sheet material; fireproofing. ETABLISSEMENTS COTTEREAU SOC. ANON., 15, Rue de Chateaudun, Paris. Feb. 12, 1934, No. 4623. Convention date, Dec. 19, 1933. [Classes 96 and 140] Viscose is applied without pressure, from distributing means to one or both faces of paper, which is moved in open air to allow " natural " penetration by osmosis, unabsorbed viscose being expressed by rollers, the paper being allowed to regain its normal thickness, the viscose then being coagulated and the web washed and dried. The web 1 from a roll 102 is successively coated on its two surfaces by rollers 104, 105 and 106, 107 which may be adjustably spaced, but which do not touch the web. The web passes downwardly over rollers 112 free or synchronously rotated from a motor 114, to avoid straining the web, alternatively inclined travelling belts may be used, the rollers 112 are on an extensible frame B as shown, with adjustment to vary the time allowed for the viscose to penetrate the web, a sliding plate 117 attached to a roller 112<a> closing the space not occupied by the frame B. The coated web passes between rollers 128, 129, one of which may be of rustless steel, copper, &c. and the other of rubber, ebonite, &c., the ends of the rollers being grooved to facilitate recovery of excess viscose. The web passes over rollers 132<a> and superposed belts 130 variable in number, synchronously driven from the motor 114 and made of rubber, canvas, &c. with slats, or a chain to ensure regular movement ; stretch can be taken up by adjustable lacing at the join. The web passes through a coagulating bath with rollers arranged as shown and having compartments to allow variation of the duration of treatment. The coagulant which is heated and stirred in the tank 135 is recovered for regeneration. Washing is effected by continuously sprinkling the web from tubes 137, the web then passing through adjustable rollers 138, 139 to remove water. The web is dried in one or two stages by passing over rollers 141 heated electrically or by water, steam, &c., vapour evolved being blown off by air, at variable temperature, from a fan 142, the web is wound, and may be trimmed at 143. The frame B may be dispensed with, the rollers 112 being on an inclined plane. In two-stage drying, the fan 142 may be dispensed with, the paper passing from the rollers 138, 139 through a tunnel, air at variable temperature being supplied and exhausted through upper and lower openings. Paper for wrapping food &c. may pass through desulphurizing baths. The paper may be made non-inflammable by an ammonium sulphate or chloride bath between the washing and drying appliances. The viscose-coated paper may be combined by pressure with a canvas backing, and the resulting composite web again coated with viscose.
