Title: Improvements in disc brakes
IPC: F16D55/00
Filed: 1952-12-18
Abstract: 731,480. Disc brakes. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. W. Dec. 8, 1953 [Dec. 18, 1952], No. 32056/52. Class 103 (1). In a disc brake comprising a disc rotatable with a wheel and axially slidable relative thereto, a non-rotatable friction pad is located on one side of the disc and a non-rotatable axiallyaligned friction pad is located on the other side of the disc mounted on a plate provided with a portion on its trailing edge containing a slot within which a rocker member is located so that the plate is adapted to rock and allow the pad to adapt itself to irregularities in the braking surface of the disc when the disc pads are forced together. Fig. 1 shows an aircraft disc brake similar to that described in Specification 625,726 but having a special form of carrier plate 15. In operation, when pressure fluid is introduced into the piston and cylinder mechanisms 9 through a conduit 26, the pistons 10 move outwardly and pull the plate nut 13a secured thereto by the operating rod 11 towards the torque plate 8. The pressure plate 13 and carrier plate 15 slidably move along the segmental sectioned sleeve 12 and the discs 1, 2, 4 and 5 move axially along the slots in the wheel rim and hub respectively, until the whole assembly of discs and friction pads (24, 25) is forced together in frictional engagement, thus braking the wheel. The torque, when the brake is applied, tends to rotate the carrier plate 15 in the direction of rotation of the discs, and the triangular extension 16 to each plate is connected, through a rocker member 20, provided with a grooved seat 21 to co-operate with the seating portion 19 provided in slot 18 of triangular extension 16, to the rigid sleeve 12. The carrier plates 15 can thus rock slightly up to the limit imposed by the clearance between the ears 22 of the rocker members 20 and the sides of the recesses 23 in the slot 18, to compensate for irregularities in the braking surface of the disc. The pressure plate 13 may be provided with a triangular extension and rocker member as described in connection with the carrier plate. Specification 625,726 is referred to.

Title: Improvements in gill spinning frames
Inventor: MACKIE JOHN PRINGLE
IPC: D01H13/18
Filed: 1953-11-19
Abstract: 750,191. Gill boxes; stopping delivery; mixed fibre yarns. MACKIE & SONS, Ltd., J. Nov. 5, 1954 [Nov. 19, 1953], No. 32141/53. Classes 120 (1), 120 (2) and 120 (3). In order to facilitate threading-up, a conductor is situated between the feed rollers and gill bed of a gill spinning frame for bast and leaf fibres, especially esparto grass, so that slivers presented to the feed rollers may be guided into the gill bed and held down against the rising gill pins, a device also being provided for stopping and starting the feed of each individual sliver. When spinning esparto grass, a crimped sliver 1 is led over a curved guide 2, through a funnel-shaped guide 3 and feed rollers 4, 5 to the conductor 12, which is open at its lower side. Because the sliver 1 is pressed against the interior of the conductor 12 and maintained in a compact condition, a control of short fibres through this part of the drafting head is accomplished. It is stated that the sliver is automatically guided to the gill bed from the feed rollers and that the spinning frame is thus self-threading. When the supply of sliver is exhausted or a break occurs, sliver feed may be manually interrupted by downward movement of a handle 15 to pivot a weighted bracket 7 carrying the lower and freely rotatable feed roller 5. According to the Provisional Specification, esparto grass may be mixed with flax or jute tow to produce a stronger sliver.

Abstract: 371,902. Combined sound and picture films. NAAMLOOZE VENNOOTSCHAP KœCHENMEISTER'S INTERNATIONALE MAATSCHAPPIJ VOOR SPREKENDE FILMS, 305, Keizersgracht, Amsterdam.- (Assignees of Tonbild Syndikat Akt.-Ges.; 43, Mauerstrasse, Berlin.) Oct. 27, 1930, No. 32276. Convention date, Oct. 29, 1929. [Class 40 (ii).] Relates to processes for making talking- picture films in which light-sensitive emulsions of different compositions (e.g. of different sensitivity or granulation) are used. According to the invention, the sound and picture records are produced on a single film provided on opposite sides with emulsions of different kinds, and both records on the film are developed together. The emulsions are selected so as to be specially suitable for the sound and picture records respectively. Preferably, each emulsion does not extend over the whole width of the film, but only over such portion as is exposed during the making of the individual record. Both sides of the film may, however, be completely coated, and the unwanted portion removed from each side of the completed negative. The two layers may be made on an opaque film, which is subsequently either made transparent or is used for reproduction by reflected light.

Abstract: 872,006. Shuttleless looms; forming selvedges. WEAVING RESEARCH & TEXTILE COMMISSION AGENTS Ltd. Sept. 17, 1959 [Oct. 9, 1958], No. 32302/58. Classes 142(2) and 142(4) In a loom having two weft inserting needles m, n, moving through the warp simultaneously in close succession to lay loops of weft drawn from opposite sides of the loom, the shed being changed in a wave-like manner at the gap between the needles, selvedges are formed at both edges of the fabric by tightening the bights d of weft inserted from that edge around the loops c inserted from the other edge, thereby forming constrictions near the ends of the loops c. As the needle n emerges from the left-hand edge of the fabric, a rearwardlyinclined deflector f rises to keep the weft p forward of a pin i; as the needle m emerges, the pin i rises so that the weft r is wrapped round it as the needle m returns to the right. As the needle n moves into the shed, its weft p rides over the deflector f and drops to the right of the pin i. The pin i and the deflector f, which are operated by separate cams, then descend, the loop of weft r being cast off the pin.

Title: Improvements in and relating to the production of protective gas by means of internal combustion engines
IPC: F02B33/14
Filed: 1920-11-16
Abstract: 153,913. Muchka, J. Sept. 24, 1915, [Convention date]. Combustion-product plant.--An internal-combustion engine is employed as a generator of products of combustion, for use as a protective inert gas in the storage of inflammable liquids. Part of the exhaust gases from the engine cylinder a escape during the latter part of the expansion stroke through a mechanically-actuated valve k to a pipe m, and the rest of the exhaust escapes through the ordinary exhaust valve d to the atmosphere during the exhaust stroke. In the event of a missfire, the pressure in the cylinder a does not rise sufficiently to allow the unburnt gases to enter the pipe m when the valve k is open. The gases admitted to the pipe m pass through a cooler n and a purifier (not shown) to the inlet valve h of a pump e driven from the engine shaft. From the pump e the gases pass through a pipe j to a storage vessel. In a modification, the pump cylinder is in line with the engine cylinder a, the pump piston being a reduced extension of the power piston.

Nov. 23, 1931, No. 32443. [Class 109.] String for use as insulating material for telephone cables &c. is obtained by passing comparatively thin sheet material formed of fibres felted together between grooved rolls 3, 4. The strip 2 of paper or like is moistened before passing through the rolls 3, 4, and the grooves 21 in the rolls have, on each side, surfaces 24 which are pressed strongly together so that the fibres between those surfaces are forced into the grooves. The product issuing from the rolls is a strip comprising strings 7 connected by fibres. The strip is dried by passing it through a drying chamber 10, or otherwise, and severed into its strings by leading the strings in divergent paths. In the case of finer strings, grooves of larger size may be provided amongst the finer grooves to form larger strings which serve to support the finer strings. Usually the strings are formed without the addition of adhesive or other material to the substance of the paper. For the production of round string of 27 mils, paper of 17 mils thickness would be employed, the density of the paper being increased between 25-30 per cent in conversion from sheet form to string.

Filed: 1934-11-19
Abstract: 447,613. Weighing - apparatus. SIMON, W. G., and SIMON, F. R., Phoenix Works, Vernon Road, Basford, Nottingham. Nov. 19, 1934, No. 33215. [Class 143] Relates to a weighing- machine of the type in which the main feed from the supply is cut off automatically when a predetermined weight, less than the required weight, has been supplied, and an additional quantity or dribble is added to make up the weight. The invention consists in providing the machine with a load indicator, a damping device for minimizing or preventing wavering of the indicator during the final stage of loading, and means for adding the dribble under the control of the operator. As shown, the beam 1 carrying a sack ring 4 is linked to a pivoted arm 12 carrying a pointer 13 which moves over a vertical scale during loading. Vibration is prevented by a double piston member 29 working in an oil-containing chamber 27, either the piston or the chamber being attached to the beam. In effecting a weighing, the main valve 9, Fig. 4, is opened by a hand lever and maintained in the open position by a toggle lever device. When the weight is almost made up the toggle lever device is automatically tripped and the gate falls into the closed position. The attendant now supplies the remainder of the charge by rotating (either by a hand wheel or a switch-controlled motor) a fluted wheel 24 which supplies a succession of small measured quantities until the attendant stops its action at the correct weight. Specifications 15517 /90, 11936/04, 152,485, [all in Class 143], and 398,295 are referred to.
