Title: Improvements in mechanisms for producing motion of a body independently controllablein two mutually inclined directions
Inventor: SLEATH DOUGLAS
IPC: B23K7/00
Filed: 1958-04-15
Abstract: 865,573. Ultrasonic flaw detection. KELVIN & HUGHES Ltd. April 7, 1959 [April 15, 1958], No. 12010/58. Class 40(7) [Also in Groups XXII and XXIV] An ultrasonic flaw detecting probe 41, flame cutting head or pen recorder is moved in two mutually inclined directions under the control of a differential gear 18, 28 the side-wheels of which are selectively driven through endless chains 19, 24. The components shown within a frame 10 are mounted thereon, and, for movement in one direction, the frame is moved on rails parallel to fixed chains 15, 15<SP>1</SP> by driving the chain 19 meshing sprocket teeth on the differential side wheel 18, which latter is also connected to a sprocket 16 meshing the fixed chain 15, which latter acts as a rack to cause bodily movement of the frame 10 in the direction of the chain 15. During such movement the other differential side wheel 28 is caused to rotate at the same speed as the side wheel 18 but in the opposite direction by a connected sprocket 27 tracking the other drive chain 24, now held stationary. The resultant rotation of the differential planet carrier with its shaft 17 is therefore zero. The probe 41 is independently traversed in the frame in a direction at right angles to the chains 15, 15<SP>1</SP>, by driving the planet carrier shaft 17, this being effected by holding the side wheel 18 by the chain 19 whilst driving the other side wheel 28 through the drive chain 24 and sprocket 27, traverse movement from the shaft 17 being obtained by driving an endless chain 40 to which the probe 41 is fast. The vertical-movement chain 19 is driven through an electromagnetic clutch 47 and a hydraulic variable speed gear 45, whilst the transverse-traverse chain 24 is driven through a bevel reverse gear 56, controlled by an electromagnetic clutch-brake 57, and another hydraulic variable speed gear 54. Separate motors, or a common motor, drive the variable speed gears, and automatic brakes 63, 64 hold the shafts if the current fails. Counters 53, 62 indicate the traverse movements and tachometers 52, 61, the speed of such movements. Limit switches may be provided for automatically stopping and reversing the movements. The frame may be moved over a tank for scanning a body immersed in water.

Title: Improved Automatic Brake Apparatus for Motor Car Trailers and Hind Carriages of Ordnance.
Inventor: PARIS ARTHUR EDOUARD CLEMENT
IPC: F41A23/50
Filed: 1917-08-22
Abstract: 128,646. Paris, A. E. C. Aug. 22, 1916, [Convention date]. Field carriages.-Relates to apparatus for automatically applying brakes by backward pressure of the tractor on gradients, applicable to the hind carriages of ordnance drawn by a tractor or attached to horse-drawn limbers, and consists in providing a diaphragm H subject to the tractive effort and adapted, when the pull is sufficiently relaxed, to force oil or other liquid past a loaded valve J so as to apply the brakes by means of a piston G. A spring C acting on the diaphragm H is normally compressed, by the tractive pull, and a spring E behind the piston G releases the brakes. The diaphragm H is loose on the rod D and bears against a head I on the rod, so that slight relaxations of pull do not apply the brakes. The oil is replenished from a reservoir N by means of a valve L which is opened by the piston G. A float valve 0 allows escape of air.

Title: Hydraulic control system for vehicle or like brakes
IPC: B60T13/14
Filed: 1941-09-19
Abstract: 552,149. Hydraulically-operated brakes and other devices. SOC D'INVENTIONS AERONAUTIQUES ET MECANIQUES, S.I.A.M. Sept. 19, 1941, No. 12138. Convention date, Sept. 20, 1940. [Class 103 (i)] In a hydraulically-operated brake system, low pressure liquid is first supplied to the brake cylinders in an application, to take up the slack, by a relay valve operated by a main valve which then supplies high pressure liquid to apply the effective braking pressure. High and low pressure accumulators 3, 4 are connected by pipes 16, 9 respectively, to the main control valve 6 and to a relay valve 12 which comprises a piston slide valve 31 subject to the pressure in a branch 40 of the pipe 11 by which the main valve 6 is directly connected to the pipe lines 10 leading to the brake operating cylinders 1. The pipes 10 are normally connected to the exhaust tank 8 through the valve 12 and pipe 36 as shown, the valve 32 being seated. A spring-urged non-return valve 39 is preferably interposed in pipe 36 to retain a light pressure normally in the pipes 10. A valve 13 spring-urged upwardly to its seat normally cuts off the main valve 6 from the pipes 10. Non-return valves 37, 38 are also provided. The main valve 6 may be such as described in Specification 443,448, [Group XXXIV], and thus adapted to establish a pressure in the pipe 11 dependent upon the pressure applied to the pedal 7. Upon initial operation of the pedal liquid is supplied from the high pressure accumulator 3 to pipe 11 and operates the valves 32, 31 of the relay to supply liquid from the low pressure accumulator 4 through pipe 9 to pipes 10 until upon further operation of the pedal the pressure difference in pipe 11 rises sufficiently to effect opening of the valve 13 to permit connection of the high pressure accumulator to the pipes 10, return flow from these pipes to pipe 9 being presented by the non-return valve 37. In charging the accumulators, the pump 5 first supplies the accumulator 4 until the piston 21 contacts the top of the accumulator. A valve in a casing 24 and acted upon by the pressure acting against a spring then cuts off this accumulator from the pump. According to the Specification as open to inspection under Sect. 91 the invention is not confined to brake operation. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,025,956. Laminates. GENERAL ELECTRIC CO. March 27, 1963 [March 27, 1962], No. 12170/63. Heading B5N. A tape suitable for electrical insulation which is to be impregnated with a resin comprises a sheet of siliceous material such as asbestos, mica or glass in the form of a paper or flakes, a backing layer of glass cloth or glass fibres and a bonding layer of a fused thermoplastic material which has no sharp melting point and no high fluidity at elevated temperatures, e.g. polyethylene, polypropylene, polybutylene, polystyrene, polyvinyl acetate, polyacrylate, cellulose acetate, cellulose acetobutyrate or polyvinyl acetal, or blends thereof. The tape may be impregnated before or after it is applied to the structure to be insulated and suitable resins are epoxy resins, polyester resins, polyimides and silicones. The tape is made by superposing the three layers and passing them over or between heated rollers or by winding the layers on a roll and heating in an oven to fuse the thermoplastic layer. Alternatively the backing layer may be a metal foil and the laminate may be used for the manufacture of condensers.
Patent GB-597927-A (GB)
Title: Improvements in or relating to time fuzes for projectiles of the rocket type
IPC: F42C9/04
Filed: 1942-08-28
Abstract: 597,927. Projectile fuzes. KEALY, W.A. Aug. 28, 1942, No. 12182. [Class 9 (i)] Relates to setting apparatus for the clockwork time fuzes of rocket projectiles or mortar and air. craft bombs, and consists in utilizing the effect of an external magnetic field on one or more armatures carried by the fuze to impart a clockwise or anticlockwise rotational movement to a setting device that governs release of the striker after a predetermined time. The setting takes place when the projectile is mounted ready for launching, the fuze casing being of non - magnetic material. In the form shown, a setting ratchet - wheel 37, connected by a sleeve 23 to the clockwork timing - train spring 24, is operated alternatively by a pawl 36 on an oscillating armature 31 for movement in one direction, and by a pawl 42 on a second oscillating armature 32 for movement in the opposite direction. The armatures are oscillated by magnetic impulses externally applied so that a given number of impulses produce a predetermined setting rotation. Means, such as depending legs 38, 44 on the pawls, ensure that when one pawl is operative the other is inoperative. The ratchet-wheel 37 is operated directly against spring action during the forward stroke of one armature and indirectly by the spring during the oscillation of the other armature. The spring striker 8 of the fuze is released in known manner when the holding catch 21 is removed by the entry, as the train revolves, of a leg 25 on the catch into a recess 28 in a disc 26 on the setting mechanism. By rotation of the time ring 6, the fuze may be set (1) to the safety position shown, (2) to a position for magnetic setting, and (3) to a position for manual setting. As shown, the pivoted detonator shutter 1 has lugs 3, 4 co-operating with surfaces on projections 5 of the ring to position the shutter out of line with the striker 8. When adjusting for magnetic working, projection 5 engages lug 3 to move the detonator 7 into line with the striker and to move lobe 9 out of the path of a detent 10. This detent sets back on firing, arms the fuze, releases the clockwork pallet 12 and permits a spring-operated shutter 15 to withdraw by engaging a slot 18 in the detent. The rate of set-back of detent 10 is controlled by a train and escapement operated by a rack 14. When the timing ring 6 is rotated for hand setting, a rack 48 on the ring drives through wheels 49, 50, 51 a sleeve 52 carrying a cam-plate 47. This plate has a recess 46 engaged by a leg 43 to release the pawl 42, thus permitting ratchetwheel 37 to return and cancel any previous setting by the armatures. Further movement of the time ring then rotates wheel 37 by stud 53, arm 54 and stud 55. The Provisional Specification states that a single armature continuously rotated in either direction by a rotating magnetic field may be used. Adjustable means for attaching the fuze to the gaine with the armatures in correct angular relation to the external electromagnets is also described.
