Title: Improvements in or relating to sub-assembly units for electrical components
IPC: H05K7/08
Filed: 1949-10-12
Abstract: 664,024. Making electric components. PHILIPS ELECTRICAL, Ltd. Oct. 12, 1949 [Oct. 15, 1948], No. 26186/49. Classes 83 (ii) and 83 (iv). [Also in Group XXXVI] Twisting wires togetlter.-A jig for assembling a sub-assembly unit for carrying electrical components comprising at least one insulating mounting plate 11 supporting the components 25, consists of a frame 3 supported above a base 1 by screw-threaded spindles 5 and holding the plate 11 in an aperture 9. The plate 11 contains holes 13 for the connecting wires 23 of the components and external wires 27. Located in the base 1 are members 17 having holes 21 registering with the holes 13. Groups of wires to be connected are inserted through the holes 13 into the holes 21, the members 17 together with the spindles 5 then being rotated by a handle 19. This twists the groups of wires together at the same time withdrawing the frame from the base 1, from which it is removed to enable the groups of wires to be dipped into a bath of solder. The unit may then be removed from the frame and mounted on a base-plate, e.g. a radio chassis. When it is more convenient, the twisting of the wires may be effected by a hand-tool shaped like one of the members 17.

Title: Improvements in hydraulic rams, or pressure transformers based upon the principle ofthe hydraulic hammer shock
IPC: F04F7/02
Filed: 1928-09-14
Abstract: 297,121. Faure, E. Sept. 15, 1927, [Convention date]. Hydraulic means. - A multiple - pipe hydraulic ram comprises two members 1, 2 which, when joined together, form pipes 3 preferably of spiral shape as seen in Fig. 2. The inner ends of the pipes open into conduits 4 controlled by a rotary valve 6 which alternately connects each pipe in turn to the low pressure chamber 11 and the high pressure chamber 9. The feed liquid enters the pipes through a port 20, and the high pressure liquid leaves the casing 12 by a port 22. The pipes are separated from the low and high pressure chambers by spring plates 16, 18, provided with packing members 17, 19. The plates may be omitted if the members 1, 2 are elastic enough to form water tight joints with the casing 12. In another form, the feed port and low pressure chamber open into the suction side of a centrifugal pump which delivers to the pipes 3, the pump rotor being on the same shaft as the valve 6.

Patent GB-250846-A (GB)
Title: Improvements in pneumatic braking apparatus for railway vehicles
IPC: B60T15/04
Filed: 1925-04-06
Abstract: 250,846. Howe, W. K. April 6, 1925. Fluid-pressure. - The manually-operated driver's valve of a fluid-pressure brake is adapted also to be operated automatically to apply the brakes, the arrangement being, such that when an automatic brake application is initiated, it cannot be prevented by the driver, but may be converted by him into an emergency application. Rotatably mounted on the valve stem 38 which operates the usual rotary valve, 36 of the driver's valve is a gear sector 45 which is engaged by a rack 46 attached to a piston 49 working in a cylinder 31 and normally held in the position shown in Fig. 1 by a spring 50. On the valve stem 38 is also mounted, slidably but non-rotatably, a collar C provided with a lug 53 adapted to be engaged by the edge of the sector 45 when the latter is rotated in an anticlockwise direction; a lug 64 adapted to be engaged by a pin 63 when a stem 60 carrying the brake handle 71 is rotated in an anticlockwise direction: and a lug 67 to which one end of a coiled spring 65 is connected, the other end of the spring being attached to the stem 60. The valve 36 can thus be moved positively to application position either by the sector 45 or by the handle 71, but can be restored to release position only by the action of the spring 65. The supply of pressure fluid to the cylinder 31 is controlled by an electrically-operated valve E.P.V., which, with the solenoid 84 energized, is held in the position shown, to connect the cylinder to atmosphere at 89 through a valve 86, but drops, when the solenoid is de-energised, to close the valve 86, and open the valve 85 to connect the cylinder to the main reservoir at 87. The piston 49 is then moved to the left and the sector 45 operates the collar C to move the valve 36 to application position. If the handle 71 is free, it will partake of this movement under the action of the spring 65, but if it be held by the driver or be moved towards release position, the movement will take place against the action of the spring, which merely becomes further tensioned. When the valve 36 has been moved to service position. the movement of the rack is arrested by its contact with the valve casing. The driver can then manually operate the valve 36 to emergency position if necessary. When the coil 84 is again energized and the cylinder 31 vented, the spring 50 will return the rack 46 and sector 45 to normal position, but the valve 36 remains stationary, and the driver can then release the brakes normally, the spring 65 being sufficiently tensioned to move the valve 36 when the opposing pressure of the sector 45 has been removed. The control of the valve E.P.V. may be effected by an electropneumatic valve controlled by means partly on the track, and a contact segment is provided on the collar C, adapted, when the latter is in application position to close an acknowledging circuit which then prevents actuation of the control devices governing the operation of the valve E.P.V.

Title: Improvements in the Smelting of Iron Ores
Inventor: DAVIES WILLIAM
IPC: C22B1/242
Filed: 1967-06-09
Abstract: 1,164,196. Producing iron. W. DAVIES. May 27, 1968 [June 9, 1967], No.26778/67. Heading C7D. Iron is produced from iron ore in a shaft furnace by a process of complete direct reduction, wherein all ore is charged to the furnace in the form of pellets composed of fine particles of ore and low volatility carbonaceous fuel such as coke or anthracite, intimately mixed with or without added flux-forming constituents. No solid carbonaceous fuel is added to the furnace other than that present in the pellets, the ratio of carbon to ore being high enough for complete reduction of all oxidic iron compounds of the ore but not exceeding the stoichiometric amount required for reduction by more than 20% by weight. In practice 4% by weight of the final melt is carbon, also supplied by the pellets, and generally the weight of carbon in the pellets is 15-25% of that of the iron ore. Fluxing materials, if present, are used to form a basic slag, generally with CaO; SiO 2  in the range 1À15-1À40. The pellets are of such a size to produce a gas-permeable burden in the furnace i.e. generally#"- 2" diameter, and so bonded e.g. with sodium silicate, to retain their form until reducing and slag forming reactions occur. 85 per cent of materials used to produce pellets should be preferably below 1 mm diameter. Pellets incorporating fluxing limestone are strengthened by replacing some limestone by quicklime. At the reaction temperature the carbon of each pellet reduces the greater part of the oxidic iron compounds of the same pellet to iron, producing carbon monoxide, which is burnt in a blast of air or air/O 2  mixture to provide the heat necessary for the reducing and slagging reactions to proceed. Heat efficiency is improved by injecting a small amount of liquid or gaseous fuel at the tuyeres, and also by recirculating some gases from the upper part of the furnace to lower regions.

Abstract: 370,335. Door-operating appliances. TEVES MASCHINENUND ARMATURENFABRIK GES., A., 23, Gustavsburgstrasse, Frankfort-on-Main, Germanv. Sept. 25, 1931, No. 26815. Convention date,-May 30. [Class 65 (i).] The main pistons 5, 9 for operating folding doors contain small inner pistons 7, 11 for commencing the opening and closing motions. Operation is effected by a hand-lever 1 which .is attached.to a rod 3 loosely connected to the pistons 7, 11. To close the doors the lever 1 is pulled over in the direction of the arrow a and a large fluid pressure is set up by the small piston 11. The pressure is transmitted by the fluid in passage 13, cylinder 8, conduit 16 to the piston 19 which operates the doors by a rack and pinion 20, 21 and linkwork 23, 25, 27 and 22, 24, 26. After the piston 11 has travelled a certain distance it comes into abutment with the large piston 9 through the collar 34. The subsequent movement of the large piston 9 compresses a larger quantity of fluid, and moves the piston 19 more quickly.
