Title: Improvements in pneumatically operated electric switches
IPC: H01H33/32
Filed: 1934-06-04
Abstract: 437,462. Actuation of switches. WEST & CO., Ltd., A., JOHNSON, C., and PADDOCK, W. J., Lewes Road, Brighton, Sussex. June 4, 1934, No. 16584. [Class 38 (v)] Pneumatic actuation.-A control arrangement for a pneumaticallyoperated switch comprises a control valve, through which the switch cylinder can be connected alternatively to a source of pressure for closing the switch or to exhaust for opening the switch, and an overload valve which, on overload, cuts off the cylinder from the source of pressure and connects it to exhaust independently of the control valve. The control valve, Fig. 1, is provided with an inlet port 2, an outlet port 3, and an exhaust port 4. When the control winding 1 is energized an armature 16 is attracted, and the inlet port 2 is connected to the outlet port 3 to supply pressure to the switch cylinder for closing the switch. To open the switch, the winding 1 is de-energized, and the outlet port 3 is connected to the exhaust port 4. The overload valve, Fig. 2, has an inlet port 6 connected to the outlet port 3 of the control valve, an outlet port 7 connected to the switch cylinder, and an exhaust port 8. Under normal conditions the ports 6, 7 are in communication and both are cut off from the port 8 by a valve member 23 controlled by a spring 28, but on overload a winding 5 attracts an armature 24 and raises the valve member 23 to cut off the port 7 from the port 6 and connect it to the exhaust port 8 so that the switch cylinder is rapidly exhausted and the switch opens. The armature is held in the raised position by a latch 32, and the switch cannot be reclosed until the latch has been released by energizing a winding 39.

Abstract: 646,555. Stud and socket fastenings. FAIREY AVIATION CO., Ltd. June 25, 1948, No. 17172. [Class 44] The socket member of a stud and socket fastening, shown in an exploded view in Fig. 2 and assembled in Fig. 3 comprises an apertured body member 15 secured by screws to one of the parts 10 to be fastened, a rotatable socket 13 having a spigot 12 bearing in the hole 11, the T-head of the stud passing through the aperture 23 in the body and being received in the aperture 22 of the socket 13. A circlip 16 carried between the body member 15 and a shim washer 21 has a projection 16a engaging in one of the notches 17, 18, 19 on the socket 13 and serves to retain it in one of a number of positions. The T-head 29, Fig. 3, of the stud. can only be engaged in or released from the socket when the slots 22, 23, Fig. 2, are aligned. When engaged together the head and the rotatable socket 13 are turned by means of a screwdriver slot 31 in the head and the head is retained by the action of the circlip 16 on the rim of the socket 13, in the locking position where it lies across the slot 23. The stud 28, Figs. 1 and 3, has a screwed shank adjustably engaged in a barrel 27 slidably guided in a bracket 25. A conical spring 26 engages under a flange 34 on the barrel to urge the stud to the extended position and to centre it in the opening 39 in the part 38. Slots 35 in the flange 34 engage over ribs 33 on the bracket 25. In the fully extended position the flange is disposed beyond the ribs and may therefore be turned to the locking position. When in the free position the stud may be forced back so that it does not project beyond the surface of the part 38 and may then be turned to engage the flange behind the ribs 33. By this means the stud is retained in a withdrawn position so that the parts to be fastened, e.g. an aircraft cowling may be slid one over the other.. The slot 23 in the body 15 has a flared entrance 40 and the stud has some degree of wobble so that it readily enters the socket even when slightly out of alignment. Specification 646,556 is referred to.

Title: Process for the thermal production of magnesium
IPC: C22B5/04
Filed: 1956-06-04
Abstract: Magnesium is produced from magnesium oxide, or substances containing magnesium oxide, by reduction with metallic reducing agents which yield no volatile reaction products other than the magnesium, the substance containing magnesium oxide having a grain size of 0.5-20 mm. and being loosely mixed with reducing agent having any grain size up to 20 mm. and introduced into a reaction furnace to undergo reaction at a temperature above the solidus curve of the reducing agent.  The reducing agent may contain ferro silicon, aluminium, silico-aluminium or calcium-silicon. The reaction mixture may contain reducing agent in stoichiometric amount required for the reaction or in a lesser amount, the reaction being interrupted as soon as the content of reducing agent is insufficient to maintain a satisfactory reaction velocity.  Alternatively, the reducing agent may be present in sufficient excess to allow the reaction to proceed to completion at a satisfactory velocity.  Excess reducing agent present in the furnace after reaction may be recovered for re-use.  When a ferro-silicon containing 40-50% of silicon is used a fluoride should be present in the reaction mixture.  The reducing agent may be used partly in lump form and partly in finely powdered form or it may be free from powder.

Title: Process for the production of ready-for-use soups and sauces in powdered form
IPC: A23L23/00
Filed: 1961-05-11
Abstract: Soup and sauce powders which comprise fat and insoluble and soluble non-fatty constituents and which disperse readily in hot or cold liquid are made by melting the fat, blending the insoluble constituents with the molten fat to form a uniform paste, allowing the paste to harden by cooling, grating the hardened paste, and mixing the gratings with the soluble constituents.  The process allows the use of rapid-swelling ingredients such as potato flour and alginates without agglomeration on adding the liquid. Examples are of making (1) a tomato soup preparation by incorporating a melted arachis oil with soyabean lecithin at 60 DEG  C into a mixture of potato flour and potato and tomato powders, moulding to slabs and hardening at 10 DEG  C, grating the slabs through a 1-3 mm. hole rotary grater, and enveloping the gratings in a mixture of skim milk powder, sodium chloride, monosodium glutamate, sugar, pepper, citric acid and onion powder (2) an oxtail soup preparation by incorporating a melted fractionated palm oil with soyabean lecithin and soya sauce at 60 DEG  C into a mixture of tomato, carrot, turnip, onion, leek and parsley powders and meat extract in potato flour, moulding to a slab, allowing to cool and harden, grating, and mixing the gratings with a mixture of a meat extract-lactose preparation, skim milk powder, sodium chloride, monosodium glutamate, pepper and curry, garlic, laurel and clove powders (3) a Julienne soup preparation by incorporating a melted hydrogenated cottonseed oil at 60 DEG  C into a mixture of potato flour, solubilized starch, mixed vegetables in powdered form and soyabean lecithin, moulding to a slab, allowing to cool and harden, grating, and mixing the gratings with a mixture of a meat extract on lactose preparation, skim milk powder, sodium chloride and monosodium glutamate.
