Patent GB-133278-A (GB)
IPC: F16D41/00
Abstract: 133,278. Allen, J. D., and Mosher, C. C. June 5, 1919. Differential gearing for motor-vehicles comprises a driving casing 3 surrounding ratchet-wheels 14 to be driven. A spider 8 has lugs 7 protruding through slots 6 in the casing 3. Pawl containers 11, each with a. patrol oppositely-directed spring pawls 18, are adapted to rock in recesses in and one each side of the spider 8 over the wheels 14, so as to bring the pawls alternatively into engagement.

Kormal overrunning is allowed by each pawl. Reversed driving or acceleration of the driven parts rocks the containers, changing the pawls.
Patent GB-133552-A (GB)
IPC: F41A3/40
Abstract: 133,552. Imray, 0., (Colt's Patent Firearms Manufacturing Co.). Aug. 9, 1918. Breech actions, sliding breechblock.-Relates to firing-mechanism, for gas-operated guns, adjustable for single-shot or continuous firing. According to the invention, the sear, which engages a notch in the actionbar, is mounted on a slide movable in a recess in the trigger-plate, and is actuated by a pawl on the trigger, the pawl being controlled by an adjustable stop so that it releases the sear for single-shot firing and holds it depressed for continuous firing. The invention is shown applied to the rifle described in Specification 133,379. The sear u is resiliently mounted on a slide e which is pressed rearwards by a spring g. The sear-operating pawl W on the trigger is controlled by an inclined surface e<5> on the slide e and by an adjustable stop T which comprises either a transversely-sliding rod T, Fig. 4, having notches of different depths, or a rotary notched spindle. When the stop is adjusted for singleshot firing as shown in Fig. 3, the pawl W is turned forwards at the end of the trigger pull to release the sear by means of the inclined surface e<5>. When the stop is adjusted for continuous firing, forward movement of the pawl w is prevented by a tail on the pawl engaging the stop, and the sear is held depressed. In the safety position of the stop, the trigger is held against movement. In Figs. 7 and 9 is shown a rotary stop T<1> operated by a lever t<2> which can be set into one of the three positions X, Y, Z corresponding to single shots, continuous firing, and safety respectively. A spring pin t<1> prevents the lever t<2>, when it is being moved from the position X to the position Y, from being accidentally moved too far to the safety position Z.

Abstract: 1,261,515. Non-woven plastics net structures. T. J. SMITH & NEPHEW Ltd. 13 March, 1969 [20 March, 1968], No. 13411/68. Heading B5B. A non-woven net-like openwork structure of thermoplastics material comprises a plurality of bosses arranged in a plurality of rows extending uniformly throughout the structure, all of which bosses are integrally joined to at least two other such bosses by bands of thermoplastics material, said bosses being of at least two different configurations, and the area of the structure between the bosses and the bands being devoid of thermoplastics material. In a first embodiment (Fig. 2), the bosses are alternately octagonal, 12, and square, 14, and are connected as shown by bands 22. Other embodiments are similar but have various patterns of bosses of different shapes-square, octagonal, hexagonal and elongated-and different sizes, connected by bands of different widths (Figs. 4, 6, 8, not shown). The openwork structure is produced by biaxially stretching a sheet of thermoplastics material having a pattern of bosses or depressions on at least one surface until the material takes on a degree of permanent set and splits occur in the thinned material. In the first embodiment the openwork structure is made from a sheet having the appropriate pattern of bosses 12, 14 formed thereon with a profiled roller (Fig. 1), the thinner material 20 between the bosses forming the connecting bands 22 when stretched as indicated by the two arrows. An openwork structure may also be produced comprising at least one portion made as above and at least one other portion having identical bosses.

Filed: 1925-05-26
Abstract: 260,312. British Celanese, Ltd., Palmer, C. W., and Fulton, S. M. May 26, 1925. Yarns and threads, treating with liquids.-The delustring of threads, &c. composed of or containing cellulose acetate silk, is controlled to any desired degree by subjecting the materials to treatment with delustring media., such as hot or boiling water or aqueous solutions or moist steam, in the presence of a protective substance, the proportion or concentration of the latter being less than that required for the complete prevention of delustring, such as is described in Specification 246,879. Suitable protective substances are soluble salts, particularly neutral salts and preferably readily ionizable salts; examples aresulphates, chromates, chlorides, nitrates, acetates and oxalates of ammonium, lithium, sodium, potassium, magnesium, and aluminium. Sugars particularly cane sugar, may also be used, and these may be employed in an amount sufficient to prevent complete delustring of the cellulose acetate threads &c. The degree of delustring will depend on the protective substance selected, and the concentration thereof, and on the nature and temperature of the bath used for the treatment of the silk and also the duration of the treatment; by a suitable selection of these conditions it is possible to obtain products having the lustre of natural silk or other natural fibres. The process is applicable to treatments such as dyeing, crÛping, crabbing, steaming and scouring. Specifications 165,164, and 176,535, [Class 15 (ii), Dyeing, Processes &c. for], also are referred to.

Abstract: Water-soluble polyvinyl alcohols containing less than 30 per cent by weight of vinyl ester groups are prepared by reacting aqueous dispersions containing 40 to 60 per cent of polyvinyl esters of carboxylic acids with aliphatic alcohols containing not more than 4 carbon atoms at temperatures not exceeding 5 DEG  C. in the presence of not more than 2.5 per cent based on the polyvinyl ester of an alkali metal hydroxide.  Preferably 100 to 300 parts of aliphatic alcohol are used per 100 parts of aqueous dispersion. Specified esters are polyvinyl acetate, formate and propionate which may be prepared by polymerization in aqueous dispersion or suspension in the presence of polyvinyl alcohol and catalysts, e.g. hydrogen peroxide and lauryl peroxide, residual monomer being blown off with air or steam.  The polyvinyl alcohols may be freed from residual alkali metal salts by treating with a cationexchange resin, e.g. sulphonated polystyrene, and recovered by precipitation with methanol or acetone or by evaporation.

The rod g is held against rotation by a flattened head l sliding in a longitudinal slot in the bolt tail h, which is itself prevented from turning in the casing a by a projection s on a block t secured to the casing and engaging in the longitudinal slot in the tail h. A tubular mortice lock is shown having a latch bolt with a symmetrical head f so that it will yield against a spring j, bearing on the fore-end k of the tail h and in a groove at the rear of the head f, when the door &c. is pushed in either direction. The bolt may be shot forward, by a key engaging a notch n, into the position shown in Fig. 3, in which the rectangular portion of the bolt engages with the keeper so that the latch acts as a lock. The bolt is held in both end positions by one or more spring-pressed pivoted levers p lying in the longitudinal slot in the bolt tail and engaging behind or in front of a projection k<1> on the rear end of the bolt tail h. The parts k, k<1> comprise discs which serve to guide the bolt tail h. To ensure silent working, the head l of the rod g butts against a fibre washer o behind the disc k. Fixed wards v may be provided on the block t. The striking plate for the latch is provided with a slightly inclined ramp leading up to an opening having inwardly turned flanges which are slightly inclined to form a tapering hole to receive the bolt. According to the Provisional Specification, pegs or wards may be formed on the bolt tail h and a knob may be fixed to the rod g for manually withdrawing the bolt.
