Title: Improvements in or relating to supporting platforms for use in radiography
Inventor: STEADMAN ERNEST JAMES
IPC: A61B6/04
Filed: 1955-11-02
Abstract: 794,276. X-ray apparatus. WATSON & SONS (ELECTRO-MEDICAL), Ltd. Nov. 1, 1956 [Nov. 2, 1955], No. 31364/55. Class 98(1) A platform for supporting a subject for radiography consists of a platform vertically movable to adjust the subject position, and the force for moving the platform is transmitted through a chain, cable, belt or like continuous flexible member from a driving member movable parallel to a reach of the flexible member. Preferably the driving mechanism is reversible and may be disconnected from the flexible member for transport as a separate unit. As shown, the platform 1 slides vertically an guides 2 mounted between supports 3. Flexible members 4 pass over pulleys 5, 6, 7, 8 on supports 3 and are connected at opposite sides of platform 1. A stop 9, which affords assistance in mounting the platform, also slides on guides 2 and is supported by chains 10 anchored to the guides 2 and to the platform and passing round sprockets 11 on the step. The flexible members 4 are connected at points between pulleys 7, 8 by a cross-bar 17 in turn engaged by the piston 16 of a hydraulic ram 12. To raise the platform, a pump 14 is started and pumps oil from a tank 13 through a non-return valve 19 to the ram 12. When the piston reaches the end of its travel, oil flows back through a pressure relief valve 21. The platform is lowered under its own weight when a solenoid-operated valve 18 is 'opened, allowing oil from the ram to return to tank 13 via a valve 20 which controls the rate of flow of the oil and hence the speed of descent of the platform. The piston is preferably detachable from crossbar'17, so that the ram may be transported as a separate unit In a modification, the ram is replaced by a captive nut on a motor-driven lead screw.

Title: Disposable garments and method and apparatus for producing same
IPC: A41D1/00
Filed: 1956-10-18
Abstract: 815,630. Moulding garments from d ispersions of fibres. AMERICAN VISCOSE CORPORATION. Oct. 18, 1956 [Nov. 30, 1955], No. 31708/56. Class 87(2). [Also in Group VII] Garments e.g. aprons, jackets, trousers are formed by dispersing fibres 11 in a gas, e.g. air-stream provided by a blower 12. Some of the fibres may be formed within the chamber by extruding a fibre forming liquid through a tube 13. The fibres are collected on a porous mould 18 which may be impervious in parts e.g. 19 and 20 which may correspond to the arm and neck holes of a garment. The air is removed through a duct 21. The layer of fibres may be sprayed with a binding agent e.g. rubber latex or a, solution of a vinyl resin, through atomizers 24. When the fibres include thermoplastic fibres, they may be softened by introducing hot gas or steam through the atomizers 24 to cause the fibres to become tacky. The fibres are then set by introducing cold air. When the fibres are made adhesive by a solvent, vapours of the solvent are supplied through the atomizers 24, followed by flushing with air to reset the fibres. The mould is then removed, and the garment stripped from the mould. In a modification, Fig. 3, fibres are formed by forcing a fibre forming liquid through orifices in a rotating disc 32 and the fibres are collected on a muold 34 having a porous shell 37. Reinforcing fabric may be introduced into the garment by stopping the collecting of the fibres, laying the reinforcing fabric over the collected fibres, and then continuing the collection of the fibres. Regenerated cellulose or asbestos fibres may be used. The garment may be reinforced or covered with a synthetic resin sheet.

Title: Aircraft acceleration limiter
Inventor: ABICHANDANI KRISHIN PAHLAJ
IPC: B64C13/00
Filed: 1961-09-05
Abstract: 975,931. Automatic control of aircraft. LEAR Inc. Sept. 5,1961, No. 31793/61. Heading G3R. In a system for automatically controlling an aircraft about one of its axes, a combined signal indicative of acceleration forces on the aircraft, derived from electrical signals dependent on displacement of a steering control member, angular velocity of the aircraft, and linear acceleration of the aircraft, is caused to modify the automatic control if it exceeds a predetermined limit. In Fig. 1, signals from the pitch pick-off of a gyro-vertical 18 on an aircraft are applied, together with signals from a pitch rate gyro 17, to an amplifier 20 controlling a fluid-pressure servo-system 14 which actuates elevators 12 to maintain a desired pitch attitude. Positional follow-up signals from a pickoff 16 coupled to the elevators are applied to the input of amplifier 20. The signals from pitch rate gyro 17 and follow-up pick-off 16 are also applied through a condenser-type high pass filter 22 so that, in dependence on their rate of change, they modify signals from a fluid or spring-restrained vertical accelerometer 25. If the resultant signal exceeds a predetermined value, it is effective through a biased diode type dead band circuit 28 to control a second control valve in fluid-pressure actuator 14 to prevent excessive acceleration forces. Actuator 14 operates the elevators through a linkage which includes a manual control column 13 and an electrical servo 15. The actuator may alternatively be clutches for rotation in opposite directions or an electric motor operating through a rack and pinion.
