Title: Multiway directional fluid flow control valve arrangement
IPC: F15B13/04
Filed: 1971-02-01
Abstract: 1357411 Valves FLUID DEVICES Ltd 25 Jan 1972 [1 Feb 1971] 3646/71 Heading F2V A valve assembly controlling a doubleacting ram 11 has four main valves 1-4 controlled by common pilot valve 5 which in the position shown (Fig. 1) closes valves 1, 3 and opens valves 2, 4 allowing fluid to flow to the left side of the ram and exhaust from the right side, these connections being reversed when the pilot valve is shifted to an alternative position. The main valves may be defined by a diaphragm 27 (Fig. 5) loaded against circular or non- circular seats 32 by one or a pair of springs 31 in pilot chambers supplied and exhausted by a pilot spool 44 (Fig. 3) working in a sleeve 42 whose radial passages are sealed by a tube 43 contacted by the base of a solenoid actuator 23 so that the tube and the sleeve are pressed against a seal. A port plate (26) at the base of the assembly provides an inlet port communicating with the annulus around the seats 32 of valves 2, 3, an exhaust port communicating with the central passage through the seats of valves 1, 4 and work ports communicating respectively with the central passage through the seat of valve 2 or 3 and the annulus around the seat of valve 1 or 4. The inlet and exhaust ports also connect with the pilot valve. In modifications, the pilot spool can be operated by a pair of solenoids and be biased to a central position closing all the main valves, check valves 15, 16 (Fig. 1) then being provided. Alternatively the pilot spool can be operated manually or by fluid pressure. Each main valve may alternatively have a transverse sill engageable by the diaphragm instead of an annular seat, or a slidable lift valve member may be used, such member optionally abutting an upper seat in the open position to sustain pilot pressure. In each case, the pilot spool is arranged to initiate closure of the open main valves prior to initiating opening of the closed main valves. When non circular valve seats are used, the main valves may be disposed in a single row, the seats preferably being rectangular with radiused ends.

Title: Earth orbital bombs as nuclear deterents
IPC: G21J1/00
Filed: 1973-01-30
Abstract: 1361962 Dropping of nuclear devices A P PEDRICK 30 Jan 1973 4641/73 Heading F3C [Also in Division G6] The Specification asserts the feasibility of releasing nuclear energy by imparting to an atomic nucleus (e.g. by bombardment with neutrons) a spin of such magnitude that it disintegrates under centrifugal forces. It is proposed to use a nuclear device exploiting this effect as a global nuclear deterrent. Such a device, put into earth orbit, would be automatically launched earthward in response to the detection, in orbit, of radiation from the earth of such character as to imply that a conventional nuclear attack had been made by someone on earth. The orbit-based devices would be directed at the likely origins of earth based attacks. In this way, it is asserted that no-one on earth would dare use nuclear weapons. In consequence, it is also asserted that world stocks of deuterium and tritium could be applied to peaceful purposes. The Specification includes a suggested method of deriving power from such deuterium and tritium (see Division G6).

Power-operated gripping jaws 2, Fig. 2, on a drawbench carriage 1 have body portions which are substantially circular in cross-section. One or more pairs of jaws 2 are independently slidable in bores 3 in the carriage 1 and have a plurality of gripping faces 4, Fig. 3, cut at different distances from the centre line of the body portion so that the spacing may be changed by rotating the jaws 2 to suit different dimensions of " tag " ends to be drawn. Operation of the jaws is by a pneumatic cylinder 23, levers 19 and cams 12 which compress plungers 11 having push-rods 10 engaging against springs 8 in bores 9 in the jaws. The springs 8 permit independent movement of the pairs of jaws 2 where the tags are not uniform. Release of the jaws is obtained by springs 6 beneath shoulders 7 of the jaws and the shock of recoil on release of the work is reduced by a cushion of air in an annular space 11a. The hook 27 of the carriage is lowered into engagement with the chain 46 by a further pneumatic cylinder 34 through a lever 30. The supply of air to the cylinder 34 is initially restricted by a valve 44 which prevents the hook 27 from being lowered until the " tag " end of the work has been gripped. Air supply to the carriage is obtained from a lance (not shown) which is engaged by a receiver 39 on the carriage when moved to the starting position near the dies. In a modification, the jaws 51, Fig. 5, are actuated directly by pneumatic pressure and have cylinder bores 56 slidable over fixed rams 57, air being supplied to the cylinder heads 59 through passages 58 in the rams 57.

Abstract: 399,707. Producing combined sound and picture films. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on- Main, Germany. Feb. 17, 1933, No. 4972. Convention date, Feb. 17, 1932. [Class 40 (ii).] A combined sound and picture film is produced by printing on to positive film stock from a negative picture film and simultaneously recording mechanically on the positive film, by means of a stylus, sound vibrations caused by reproduction from a record, which record may be on the same film as the pictures to be printed, or on a separate film. The Figure shows one method of carrying out the invention, A negative picture film 5 and positive film 2 are moved together past a printing gate 4, whilst a synchronously driven sound film 12 is moved past a photo-electric reproducing device 13. This is connected to a recorder 9 which records on the film 2 a sound track corresponding to the record on the film 12. The mechanical sound record may be examined immediately after being made, by means of a pick-up placed adjacent to the recorder. If the sound film 12 is of the variable density type, it must be a positive. In a modification, the pictures to be printed and the sound-record to be transferred are on a single film, on which the picture record is a negative and the sound track a positive. Instead of printing the pictures by contact, they may be printed by optical apparatus, with reduction in size if required.
