Title: Improvements in or relating to mechanism for actuating vehicular brakes
Inventor: JULIER BERTRAM HARVEY
IPC: B60T11/32
Filed: 1956-07-20
Abstract: 800,218. Fluid-pressure brakes. TALCO ENGINEERING CO. July 20, 1956, No. 22622/56. Class 103 (1). [Also in Group XXI] In an emergency brake-operating means for the wheels of a vehicle, an auxiliary chamber containing brake fluid is provided which may, upon failure of the usual brake operating mechanism, be connected through a suitable valve control circuit with the usual brake operating cylinder such that the fluid in the auxiliary cylinder is normally not under pressure but is adapted to be placed under pressure by the combustion of a cartridge containing combustible gas generating material which when ignited causes it to be supplied to the brake operating cylinder to operate the brakes. In the embodiment illustrated, when switch 35 is closed by the operator when the normal fluid pressure braking system fails, ignition of the priming material 27 in casing 17 will effect combustion of the combustible material 26 and the gas pressure generated will cause piston 19 to move to the right, compressing fluid 18 in casing 17 and forcing this fluid under pressure into conduit 14 past ball-valve 23 which will be forced off its seat by the pressure generated and fluid under pressure will enter wheel brake cylinder 12 to actuate brake shoes 11 in the usual manner. In opening ball-valve 23 against the spring pressure 24, the fluid pressure generated in casing 17 also forces ball-valve 23 on to seating 37 to close communication with the normal brake conduits through conduit 15. A modification is described and illustrated in the Specification in which the auxiliary fluid chamber is separate from the cartridge gas-generating means.

Title: Device for continuous lowering of bulk products
IPC: B65G15/16
Filed: 1974-05-21
Abstract: 1415998 Endless chain conveyers; unloading bulk material from ships J PRADON 21 May 1974 [6 June 1973] 22705/74 Headings B8A and B8E Material from a conveyer 24 which discharges into a shoot 25, is fed into U-shaped elements 2 of a descending run of an endless chain conveyer 1. Each element 2 is closed by plates 8 of an endless chain conveyer 7. Each plate 8 is engaged by fastening catches 18 carried by the ends of the U-shaped sides of the members 2, by the action of cam members 33 and followers 21 (Fig. 3, not shown). The material falls from the base of the conveyer 1 on to the surface of a horizontal conveyer 28. The shoot 25, conveyer 24, and guide sprockets 10, 11, of the conveyer 7, may vary in vertical position, according to the changes in height of apparatus feeding the conveyer 24. In a modification, the shoot 25 is fixed. The catches 18 are then replaced by fixed ramps, which bring about the engagement of the plates 8 with the conveyer elements 2. In a further modification (not shown) the plates 8 instead of being carried by a conveyer 7, may be directly hinged to respective elements 2. As applied to the unloading of a ship (Figs. 4 and 5, not shown), material is fed from the hold of the ship by a vertical elevator (38) which transfers the material to a conveyer (40) carried by a horizontal boom. The conveyer (40) corresponds to the conveyer 24 of Fig. 1, and the apparatus of Fig. 1 is carried on a trolley movable along the side of the dock in which the ship is berthed.  (For Figures see next page.)

Title: Improvements in and relating to protective systems for direct current circuits
IPC: H02H11/00
Filed: 1937-08-20
Abstract: 479,333. Electromagnetic relays. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 20, 1937, No. 22900. Convention date, Aug. 20, 1936. [Class 38 (v)] A D.C. source 1 is adapted to be connected to a load 2 over a circuit-breaker, the winding 4 of which is controlled by a relay 5 energized across the source 1 in series with unidirectional conducting means 7, which only conducts when the polarity of the source is correct. Winding 5 is shunted by a further unidirectional conducting means 8 which, if the means 7 becomes internally short-circuited, and the source-polarity is incorrect, acts to shortcircuit winding 5 and prevent its operation, but with normal polarity, a short-circuit in 7 still allows 5 to be energized. An impedance 6 of relatively-high value to that of 5, limits the current through 7, 8 to a safe value.

Abstract: 796,147. Laminated fabrics. FRIEDER, L. P. Aug. 7, 1954, No. 23012/54, Drawings to Specification. Class 140. [Also in Group IX] A laminated fabric for resisting penetration by projectiles includes a multiply fabric woven from highly-twisted continuous filament yarns of nylon, glass, or metal. The yarns are twisted, whilst restrained from shortening, until the filaments are stretched between 50 and 90 per cent of the extension at which they would break, the upper limit causing permanent elongation of the filaments. Fabric made from yarns twisted to the upper limit are more effective against sharp-nosed spinning projectiles, and fabrics made from less highly twisted yarns are more effective against shrapnel. The fabrics may have a metal coating sprayed on. Two of the above fabrics, one with maximum twist and one with less twist, may be sewn together, with a layer of soft material between them, in the manner of quilting; the soft material may be a fabric woven from soft-spun yarns.

The composition may be in the form of a sol, gel, dispersion or monolithic structure. The composition may be prepared by mixing silica, its liquid dispersion form or its negative colloidal form in a sol with dispersions or sols of the positively charged colloidal materials, (e.g. alumina coated silica sols). The interaction between the oppositely charged particles may be promoted by use of a base. Filler materials which may be incorporated into positive or negative sols or coated with charged agents (e.g. negative colloidal SiO 2 ) may be refactory grains (e.g. alumina, silica, mica, boron nitride, zircon, clays, silicon carbide, ferrites, chromites and graphite), refractory fibres (e.g. alumino silicate, fibre glass, calcium silicate, potassium titanate, carbon and metal), metal powders (e.g. steel, Al, Ni and Cu) and pigments (e.g. TiO 2 , chromium oxide and iron oxides). The use of hydroxyacetic acids and wetting agents in the sols is mentioned and also the use of counter ions (e.g. Na<SP>+</SP>, K<SP>+</SP>, NH 4 <SP>+</SP>) in the negative sol. Other additives may be polymer lattices, clays, cellulosic materials, asbestos, gums and resins. The examples illustrate the use of the composition as an adhesive, as a coating composition and ceramic mould wherein the composition is prepared by spraying together of two slurries on to a substrate, as a ceramic core, as a refractory pipe casting mixture and in a metal-refractory grain composite composition.

Abstract: 187,192. Gray, W. April 16, 1921. Machine guns.-A gasactuated and spring- released safety device to prevent operation of the gun should a missfire occur, comprises a longitudinally-slidable rod 55 adapted at its rear end to enter a recess 59, Fig. 2, in a plate 60 mounted on the spindle 29 of the gun-actuating handle 31. The device is shown in central section in Fig. 2, and in part sectional plan in Fig. 3, as applied to a doublebarrel gun. At its front end the rod passes into a cylinder 51<a>, disposed between the two barrels 23 and in communication therewith by gas ports 51, and is provided with a piston 54. A spring 56 tends to push the rod 55 rearwards. When the gun is firing normally, the gas pressure in the cylinder 51a holds the rod out of engagement with the recess 59, but if a missfire occurs, the spring drives the rod into the recess 59 and stops the mechanism.
