Title: Improvements in or relating to automatic guns
IPC: F41A3/82
Filed: 1938-04-12
Abstract: 500,922. Automatic guns. WERKZEUGMASCHINENFABRIK OERLIKON. April 12, 1938, No. 11258. Convention date, Dec. 13, 1937. [Class 92 (ii)] An automatic gun, of the kind in which the breech-block 7 is not positively locked, is provided with a recoil spring 10 and two further spring systems, one of which catches the breechblock resiliently towards the end of the firing stroke while the other assists the recoil spring in accumulating energy after the breech-block has passed rearwardly beyond its initial or cocking position. In the form shown, the barrel 1, Fig. 1, is secured by a bayonet-joint to a guide-bushing 2 'which is connected to the fixed breech casing 5 by a further bayonet-joint. The breech-block is connected to two longitudinal bars 6 by a member 8 which slides in two longitudinal grooves in the breech casing. The forward ends of these bars are connected to a sleeve 11 which houses the recoil spring 10. Each bar contains a spring 13 the forward end of which bears against a bolt 12 and the rear end against a pin 14. In operation, the pins bear against shoulders 6a of the bars 6 when the breech-block is positioned forwardly of its normal or cocking position (shown in dotted lines) and the springs 13 are not compressed. When however, the breech. block, during recoil, moves rearwardly beyond this position, the pins 14 abut against a shoulder 5a on the breech casing and the springs are compressed. The second spring system comprises a number of springs 4 the forward ends of which bear against the bushing 2 while the rear ends abut against a slidably 'mounted member 3. The sliding movements of this member are limited by shoulders 5b, 2a. This member provides the resilient abutment 'for the breech-block when the latter approaches its foremost position. A pivoted member 18, Fig. 7, is provided for locking the barrel 1 and guide-bushing 2 to the breech casing 5. This member, which passes through a slot in the guide-bushing and engages with the barrel, is normally held in the operative position by the engagement of a handle 15 with a notch 5a in the breech casing. By exerting pressure on a button 16, the handle is released from the notch and can then be turned to withdraw the member 18 from the slot in the guide-bushing.

Title: Improvements in or relating to colliery and other like winding engine control apparatus
IPC: B66B15/00
Filed: 1954-04-21
Abstract: 755,878. Winding machine brakes. BLACK, G. A. April 21, 1955 [April 21, 1954], No. 11537/54. Class 103 (1). In apparatus for controlling the application of friction brakes in colliery winding mechanism and other equipment wherein the speed of a lift or cage is automatically controlled by a centrifugal governor, means are provided whereby the speed of the governor is increased as the speed of the winding engine is reduced so that the power available from the governor to operate the friction brake control valve is increased as the engine approaches the end of its wind. This form of operation is obtained by arranging for the governor 1 to be driven by a continuously-running synchronous motor 10 through reduction gearing 13, 14, epicyclic gearing 12, 15, 17, skew wheels 18, 19, and gearwheels 20, 21, the disc 29 on which the planet gears 15 are mounted being rotated by shaft 16 coupled to the winding mechanism so that as the speed of the wind is increased the effect of motor 10 on the governor is decreased and the governor may eventually be stopped. The brake control valve 9 is controlled jointly by a linkage connecting it to the governor 1 and by a connection to an arm 7 having at its lower end a roller 6 adapted to engage the profiles of rotary cams cut to conform with the normal retardation of the winder. In the control system, as shown in Fig. 6, the brake cylinders are supplied with high-pressure oil from two pumps 38 and 36. The neutral point 43 of the lever 2 of the engine brake governor is arranged to load or unload a small low pressure pilot valve 41 with a force of between 4 and zero pounds, this load causing the pressure in the pipe connection between valve 41 and control valve 42 to vary between 0 and 300 pounds per square inch, which in turn through a very small displacement of oil causes the pressure from valve 42 to be reduced from 3500 p.s.i. to zero. Specifications 552,345, [Group XXX], 701,677, 702,260 and 755,871 are referred to.

Title: Improvements in apparatus for heating liquids
IPC: F24H1/20
Filed: 1933-04-20
Abstract: 418,308. Valves. GAS LIGHT & COKE CO., DIETERICHS, W., LLOYD, P., and DINES, F. C., Horseferry Road, Westminster. April 20, 1933, No. 11565. [Class 135.] In apparatus for maintaining a liquid at a desired temperature, a differential cut-off valve s is located in the main gas supply pipe, the control chamber x of which has an exhaust passage w narrow in comparison with the main gas supply pipe, this passage being controlled by an auxiliary valve v actuated directly by a thermostat u in a chamber o through which passes vapour produced by heating the liquid. As applied to a water heater, the steam pipe passes down through the water space and through the wall of the container a where it joins a pipe n leading to the chamber o and an outlet pipe p. The chamber o contains a casing t housing a bimetallic strip u the free end of which passes into a chamber q and is connected to the valve v which closes the end of a pipe r when the heat of the steam bends the strip u. Gas then accumulates in the control chamber x and the valve s therefore closes. The container a which is suitably lagged has a reentrant conical chamber projecting from the bottom into the water space and inside this chamber extends a similarly shaped shell arranged so that the hot gases from the burner have to pass between the shell and the chamber wall before reaching the flue i. The container has a subsidiary restricted steam outlet which ensures that the gas is not cut off until the water is boiling vigorously.

Title: Improvements in or relating to the manufacture of starch base dusting powders
IPC: C08K3/00
Filed: 1952-05-08
Abstract: In making a mobile starch-base dusting powder, starch granules in water, e.g. at least 25 per cent. of water computed on the weight of starch, are intimately mixed and coated with a finely divided, freshly precipitated, water-insoluble inorganic salt or hydroxide whose particles are smaller than the starch granules and the coated starch is then dried and, if necessary, ground to a fine powder.  The starch may be dispersed in water with two water-soluble inorganic compounds which react to form a finely divided precipitate.  For example, aqueous solutions of the following compounds may be added to starch dispersions; aluminium sulphate and tri-sodium phosphate, aluminium sulphate and soda ash, Epsom salts and tri-sodium phosphate, cupric sulphate and sodium hydroxide, calcium chloride and soda ash, calcium chloride and magnesium sulphate, tri-sodium phosphate and calcium chloride, sodium silicate and hydrochloric acid, zinc sulphate and sodium hydroxide, barium chloride and sodium sulphate.  Starch may be coated with freshly precipitated magnesium hydroxide. Alternatively, aqueous solutions of aluminium sulphate and tri-sodium phosphate may be mixed and the resulting suspension of aluminium phosphate may then be mixed with an aqueous dispersion of starch.  Preferably, at least one part by weight of the water-insoluble salt or hydroxide is used to coat each 6800 parts of starch.ALSO:In making mobile starch-base dusting powders, which may be used as carriers for fungicides, insecticides and medicaments, starch granules in water, e.g. at least 25 per cent. of water computed on the weight of starch, are intimately mixed and coated with a finely divided, freshly precipitated water-insoluble inorganic salt or hydroxide whose particles are smaller than the starch granules and the coated starch is then dried and, if necessary, ground to a fine powder.

IPC: E03D1/05
Abstract: 117,733. Holt, J. Oct. 1, 1917. Siphon-discharge water-waste preventers have two systems of levers, the one which is operated by the user permitting the second, under the action of springs &c., to start the flushing. In the construction shown in Fig. 1, the bell 6 is coupled to a lever 7 weighted at 9, and normally held by the operating-lever 10. On pulling down the lever 10 as by the chain 12, the lever 7 is permitted to rise and start siphonic action. In other modifications, the lever 7 is moved by a spring instead of the weight. In Fig. 3 the lever 7 is shown resting in a fork 15 pressed upwards by a spring 13a. On pulling the rod or cord 12<a>, the weight 9 operates the lever 7. To ensure that the siphonic action shall start, a shoulder 6<a> normally below the surface of the water may be formed on the bell. Figs. 4 and 5 show a construction in which the position of the controlling lever can be varied. The lever 10 is pivoted on a bracket 15 adapted to be angularly adjusted and held by the projections 18<a> on the cover. The lever 9 is normally held by a cap 18 resting on the rod 17, but on operating the chain the cap is raised, permitting the bell to rise. The releasing lever may be operated by a chain, as shown, or by other means either electrically or pneumatically.

IPC: B60T13/16
Filed: 1969-03-06
Abstract: 1,268,932. Anti-skid braking systems. SIMMS GROUP RESEARCH & DEVELOPMENT Ltd. 2 March, 1970 [6 March, 1969], No. 11902/69. Heading F2F. In a braking system for a vehicle wheel including brake operating means, a pump 15 having a liquid output adapted to increase with wheel rotational speed is arranged to withdraw liquid from a reservoir 13 and return the liquid thereto after circulation through a conduit having a connection to the brake operating means, and brake applying means located downstream of the connection is operable to add a restriction into the conduit and arranged so that liquid pressure in the connection is increased. A leakage path by-passes the brake applying means and incorporates a variable restriction providing a resistance to liquid flow which decreases automatically with increased wheel rotational speed, and a fixed restriction in series with the variable restriction. As shown, depression of a brake pedal 1 results in fluid pressure from master cylinder 3 being applied via conduit 6 and annulus 7 in valve 5, conduits 10 and 11 to the brake applying means of the wheel 12, fluid fed by the pump 15 to a conduit 16, via conduits 29, 33 and conduit 28, to reservoir 13 and not being obstructed by tapered portion 8 of the valve 5. Further depression of the pedal 1, causes the portion 8 of the valves to obstruct the connection between conduits 33, 28 and fluid pressure generated by the pump is applied to the plug 31 in cylinder 30 comprising the brake operating means to apply the brakes; this generated pressure can leak back via conduit 28 via the leak off path provided through conduit 19. In the leak-off path is a spring- loaded shuttle 22 having tapered flats 23 which create with an annulus 25 a variable restriction in series with a main restriction 27. With high rotational wheel speeds a relatively high differential pressure is generated across a sensing restriction 17 to force the shuttle to the left as seen in the Figure to render the main restriction 27 unaffected with low rotational wheel speeds, the shuttle is urged by spring 24 towards the right when the restriction 17 controls the leakoff path. The restriction 17 may be incorporated in the housing of the shuttle 22. The system may be applied to each wheel of a vehicle, there being a pedal 1 and master cylinder 3 common to all systems, or applied to pairs of wheels and the pump may be driven directly by a wheel or some other part of the vehicle transmission.
