Title: Improvements in methods and apparatus for measuring altitude and changes in altitude
Inventor: PARRISH JOSEPH REGINALD
IPC: G01S17/08
Filed: 1970-03-17
Abstract: 1281450 Photo-electric distance measuring PARRISH INSTRUMENTS Ltd 19 April 1971 [17 March 1970] 12765/70 Heading H4D In a method, and analogous apparatus, for  determining the height of an aircraft above  ground a beam of modulated light is projected from the aircraft and rotated about an axis, the instant when a reflection from the ground or the beam is detected by a photo-senser 57 at the upper end of a collimator tube on the aircraftthe tube being direct downwardly-is registered so as to derive the angle # of the beam at the instant of detection, the photo-sensor is located at a known distance from the axis of rotation of the beam and the height is determined from the angle and the distance. In an embodiment a pulsed infra-red source, e.g. GaAs lamp(s) 40 or a laser, produces a beam which is rotated by means of a double-sided mirror 42 driven from a motor 43, a photo-electric slotted pulse generator 44 (see also Fig. 2, not shown) produces pulses which cease when a gate 56 is activated by pulses from sensor 57. It is arranged that the latter is sensitive only to light having the same modulation as that from source 40. Pulses on line 55 are held in stores 60, 61 during alternate half-cycles of mirror rotation and their outputs are fed via D/A converter 62 to mark a recording drum 45. Since the latter is rotated at a known speed, vertical aircraft velocity can be derived. Pulse generator 44 may have slots spaced according to a tangent scale so that the number of pulses in store 60 or 61 gives tan 0 directly.

IPC: F16G1/16
Filed: 1949-05-13
Abstract: 675,205. Endless-belt conveyers. SIEGLING, E. May 13, 1949. No. 12791/49. Class 78 (i). [Also in Groups VIII and XXIV] A laminated driving or conveyer belt includes a layer of a polyamide, polyurethane, or like polycondensation resin that has been longitudinally oriented by stretching, the tendency of this layer to split being reduced or eliminated by reinforcing it with transverse threads, which may be the wefts of a woven fabric or may consist of metal wire. The transverse threads may be perpendicular or at an acute angle to the longitudinal direction of the belt. The threads may be secured to the resinous layer by the same or similar resinous material either molten or dissolved in acid such as formic acid. When metal wires are used, they should be pressed into the plastic layer, or embedded between two layers. The threads may be impregnated with a material which increases friction or hygroscopicity or eliminates electrostatic effects ; calcium chloride is specified. As shown, a friction layer a of split leather is united to a tension layer b of polyamide which is reinforced by a woven fabric c of cotton or wool, the three layers being united by a solution of polyamide in formic acid.

Title: Improvements in suspension devices for releasably holding the rear ends of rockets
IPC: B64D1/04
Filed: 1955-05-03
Abstract: 769,139. Suspending and launching rockets from aircraft. BREVETS AERO-MECANIQUES SOC. ANON. May 3, 1955 [May 20, 1954], No. 12830/55. Class 9 (2). Rockets 4 are suspended beneath an aircraft wing 1 by means of slidable tail units 3 and 'holding devices P carried by a retractable support 5 and provided with locking means adapted to be released by the thrust of the propellant gases. The device P, Fig. 3, comprises pivoted jaws 6 engaging the flared end of the rocket and carrying transverse pins 8 engaged (in hooks 9 'to lock the jaws. The hooks 9 extend from a slidable member 10 held by a spring 11. The jaws 6 are pivoted on a sleeve 12 slidable in an extension 5a of the support 5, resilient means 13. eg. Belleville washers, being arranged around the sleeve 12 to urge it -rearwardly in the tube 5a. Within sleeve 12 is a tubular rotatable element 15 carried by a control lever 16 and having a finger 17 engaged in a helical groove in the hub of member 10. On the lever 16 is a cam 19 which closes a switch 20, when the jaws 6 are locked, to connect the rocket to the firing device. A spring-biased locking finger 21 mounted in the lever 16 holds the lever in the circuit closing position. From the member 10 projects a plug 22 adapted to enter the rocket nozzle and make electrical connection with the ignition means in the rocket, the conductors being lead to the plug through the tube 15 to a connector 23 such as a microswitch. Fingers 24 on each side of jaws 6 guide the rocket when being inserted and launched. To insert a rocket, lever 16 is used to rotate the tube 15 and so retract the hooks 9 and free the jaws 6. The rear end of the rocket is then pushed between the fingers 24 until the plug 22 and the jaws 6 are engaged. On returning the tube 15 to its initial position, the member 10 moves forwardly and the hooks 9 engage the pins 8 to lock the jaws 6. Switch 20 is also closed and the rocket is ready for firing. On firing the rocket, the propellant gases force the member 10 rearwardly, so releasing the jaws 6, which are then pushed apart by the rocket. Should movement of member 10 be delayed, the thrust of the gases moves the jaws 6 and sleeve 12 forwardly, overcoming the resistance of the washers 13 and releasing the jaws 6 from the hooks. Reference has been directed by the Comptroller to Specification 738,870.

Abstract: 1,011,446. Adjustable seat back hinges. ROCKWELL STANDARD CORPORATION. April 2, 1964 [Jan. 2, 1964], No. 13596/64 Heading E2F. [Also in Division A4] An adjustable seat back hinge has two unidirectional clutch assemblies interposed between the back frame member 18 and a bracket 12 with a single release means to selectively disable one of the clutch assemblies to permit rotation of the frame member 18 in one direction while the other clutch assembly prevents movement in the opposite direction. The clutch assembly comprises a cam 34 and a flanged casing 22 rigidly secured to the bracket 12 and the frame member 18, respectively, two rockable plates 48, 50 interposed between the cam 34 and casing 22, and rollers 32, 32a disposed between inclined faces 38, 38a of the cam 34 and the inner surface of the casing 22 so that they also engage recesses 54, 52 in the plates 50, 48. Compression springs 68 are positioned between adjacent flanges of the two plates 48, 50 which force the rollers 32, 32a to the edges of the inclined faces 38, 38a and thus wedge them against movement. In operation, to tilt the backrest and thus the casing 22 in direction "A", a handle 78 is rotated in-direction "B", which causes the plate 50 to be rotated by a stud 70 against the force of springs 68, thereby displacing the rollers 32 along cam face 38 and allowing the backrest to be moved in direction "A". Release of the handle causes the rollers 32 to be wedged again. A similar movement of the handle 78 in direction "A" rotates plate 48 and thus allows the backrest to be moved in direction "B".
