Title: Improvements in power control mechanism
IPC: B62D5/06
Filed: 1944-08-17
Abstract: 604,911. Fluid-pressure servomotor-control systems. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Aug. 17, 1944, No. 15758. Convention date, Aug. 23, 1943. [Class 135] A manually-controlled power device, particularly for the steering mechanism of vehicles, in which the manual control over-rides in the event of failure of the power supply or control mechanism, is provided with means to prevent the power operation over a fixed portion of the steering range, such as the central portion when a vehicle is travelling in a substantially straight path. As shown, rotation. of a steering shaft 4 operates a lever 8 having a boss 10, provided with a certain amount of lost-motion on a fixed stub shaft 11, and connections 27, 28 to valve devices 25, 26 controlling the admission of pressure fluid to, and exhaust from, power cylinders 15, 16 which are connected by rods 19, 20 to the steering arm 13 of the vehicle wheels. Thus, movement of lever 8 provided by the said lostmotion, operates one or other of the valves 25, 26 to operate one of the motors 15, 16 to adjust the position of the steering arm 13, a connection 12 being provided between the arm 13 and the lever 8 so that a follow-up action is obtained to restore the valve 25 or 26 to neutral position. The pressure supplied to the motors 15 or 16 reacts upon piston members 37 on the valveactuating rods 27, 28 to enable the operator to " feel " the operation of the steering and the resistance thereto. Springs 40 acting against the members 37 also provide additional " feel " reaction. In the event of failure of the supply of pressure fluid or of the control mechanism, the steering can be effected manually.when the lost-motion of the boss 10 on the shaft 11 is taken up. To enable the steering to be manually operated when the vehicle is travelling on a substantially straight path, the lever 8 is provided with cams or lobes 41, 42 which in the central position of arm 13 engage with cam surfaces 45, 46 on members 43, 44 secured to the vehicle frame. Thus, over the central range of movement of arm 13 corresponding to straight or substantially straight steering, the lost-motion between the boss 10 and shaft 11 is eliminated and the steering is entirely manual, but over larger steering angles the cams 41, 42 disengage and the normal power operation is permitted: Specification 410,965, [Group XXXI], is referred to.

Abstract: 667,948. Weighing apparatus. METTLER. E., (trading as METTLER, FABRIK FUR ANALYSENWAAGEN, E.). June 23, 1950, No. 15799/50. Class 143. In a balance, the mechanism which relieves the beam knife edges comprises a vertically moving, member guided by a parallelogram linkage. The balance shown in Fig. 1 has a rigid bearing stand 4 supported by columns 5, 6, 7, 8, and members 29, 40 which, respectively, lift the beam to relieve knife edge 14 and lift the pan supporting stirrups 20, 20<SP>1</SP> to relieve the knife edges 16, 161. The member 29 which engages the beam through pins 23, 25, arranged in.a triangular formation, is secured to a rod 31 which is vertically reciprocated by an eccentric 37 on a shaft 38 and is guided by parallel links 33, 34 pivoted respectively to the base and an extension 10 of the stand 4. These links are H-shaped in plan and have adjustable cone pivots 46. Concentric with rod 31 is a tube 42 guided by a second pair of H-links 44, 45 of similar construction and this tube is vertically reciprocated by a second eccentric 47 on shaft 38 having a greater eccentricity than eccentric 37 so that the member 40, secured to tube 42, has an amplified movement relative to the member 29 and thus bearings 16, 16<SP>1</SP> are relieved before the beam is lifted. Pins 26, 27 and 26<SP>1</SP>, 271 which engage stirrups 20 during lifting are secured in triangular formations on member 40. The modified balance shown in Fig. 5 has a single pan and a fined counterweight 50, and the knife edges 16, 14 are relieved by two triangularly arranged sets of pins 26, 27 and 23, 25 secured to a common plate 29. This plate is reciprocated by a shaft 38 and rod 47 engaging a tube 42 which is guided by a pair of H links 44, 45, adjustably secured to the tube through sliding collars 41, 43 having set screws 52.

Abstract: 963,522. Ornamenting. P. W. H. GOODSON. July 2, 1963 [April 27, 1962], No. 16112/62. Heading B6G. Sheet material, e.g. paper, metal foil, or polyvinyl chloride, is decorated by applying thereto a filament, e.g. of synthetic resin. The sheet is supported on a mandrel 10 and a filament 19 is guided by wheels 18 on a carriage 15 which is traversed axially of the mandrel along a screw 14 rotated with the mandrel. The filament may be applied as a simple helix, or, by oscillating the carriage axially, in wave form. Lacquer may be sprayed from a nozzle 20 on to the sheet to act as adhesive for the filament, and lacquer from a nozzle 21 to form a smooth outer coating. Further filaments may be applied at different angles, as by wrapping the sheet at right-angles round the mandrel. A sheet of polyurethane resin may be formed on a cylindrical glass former replacing the mandrel by spraying it in liquid form on to the former and allowing it to set. The filament is then severed along an axial line and the sheet removed from the mandrel or former and uncurled.

Title: Improvements in braking-means for aircraft
IPC: B64C25/48
Filed: 1931-06-09
Abstract: 379,017. Brakes. WIGLEY, F. S. and AUSTING, L. F., Air Ministry, Kingsway, London. June 9, 1931, No. 16772. [Class 103 (i).] The wheel brakes of an aeroplane are regulated in accordance with the attitude of the machine by a ground contact which controls the fluid pressure of the braking system. The maximum degree of pressure can be controlled by the pilot and connections to the rudder bar enable the braking pressure to be reduced on one side or the other of the machine. The ground contact moves a plate 18 which tilts as the tail of the machine falls and a cam 17 carried by the plate acts on spindles 15 of two brake valves in casings 16, for supplying pressure to the brakes on the two sides of the machine. The cam 17 has inclined surfaces which are brought beneath one or other of the spindles 15 as the cam is rotated by cables 22 connected to the rudder bar. Each valve casing encloses a balanced inlet valve 39, an exhaust valve 26 and a valve 30 which can be closed by the pilot to hold the brakes indefinitely in the " on position. A lever 48 controlled by the pilot acts through a spring 46 on a Bowden cable 40 whereby the valves 30 can be opened or closed and spindles 47 depressed to a greater or lesser degree to cock springs 32 acted upon by the spindles 15. As the spindles 15 are raised the exhaust valves 26 are closed and the valves 39 opened to admit pressure to chambers 38 and passages 31, the valves 39 closing when sufficient pressure has been built up in the chambers 38 depending upon the amount of movement given to the spindles 15. According to the Provisional Specification a non-automatic supply valve in series with the automatic supply valve and a non-automatic exhaust valve in parallel with the automatic exhaust valve are provided for each brake and controlled by mechanical or hydraulic remote control so that the brakes can be independently or simultaneously applied or released, the remote control preferably co-operating with the rudder bar. The brakes comprise blocks 5, Fig. 5, with linings 5a, normally held off by springs 8 and applied to the brake drum by inflatable bags 10 supplied with pressure fluid through pipes 12 from a nipple 11 projecting through the back-plate 1. The plate 1 has a flange 2 riveted to it to support the bags 10. The springs 8 react against rollers 6 carried by bolts which secure blocks 4 to the back-plate 1. The brake system is fed from a high-pressure reservoir through a reducing valve 53.
