Title: Linear displacement devices
IPC: H02K29/10
Filed: 1972-12-14
Abstract: 1456366 Photo-electric control of displacement HAWKER SIDDELEY DYNAMICS Ltd 14 Dec 1973 [14 Dec 1972] 46618/72 Heading G1A [Also in Division H2]  In an actuator having a jack which is linearly moved by a rotary electric motor, the jack displacement is photo-electrically measured by a  MoirÚ fringe system which also produces pulses to drive the motor. In Fig. 1 the rotor 12 of the motor drives a jack which carries a grating 14. Moire fringes are produced 90 degrees out of phase at detector systems. 15, and are used to measure displacement, speed and direction at counters 23-25. The detector signals are also applied, amplified, to the field coils 13 of the motor, which is of the brushless D.C. type. The pitch of grating 14 is such that the detector pulses occur at the desired frequency relative to the motor rotation, though provided the frequency is a whole number multiple or submultiple of the desired value it can be electronically divided or multiplied to give the desired result. The measuring system can be combined with logic controls to drive the jack to a given position. Fig. 2 shows a recirculating ball screw jack, whose rotor 12 is keyed to the nut 26 and is driven by coils 13. The jack 27 carries the grating 14 which is optically sensed at 20. The jack can be used to position a gimballed rocket motor, this motor's cryogenic fuel being supplied to cool the actuator via pipes 30. If helium is used, the actuator can be superconducting 2À1‹K and 36mm pressure. The screw jack and balls can be stainless steel lubricated by an electro-plated metal, e.g. gold or lead, or by molybdenum or tungsten disulphide or niobium disellenide. The windings 13 can be copper (600‹K-80‹K) or aluminium (330‹K-4‹K) or Nb 3 Sn, NbTi, V 3 Ga on stainless steel (superconductive).

Filed: 1970-10-05
Abstract: 1317916 Locks AISIN SEIKI KK 5 Oct 1970 [4 Oct 1969] 47173/70 Heading E2A A door latch for a motor vehicle comprises a rotary latch bolt 18 that has a slot for engaging a pin 12 of a striker 10 and is biased in the releasing direction and a striker contacting member 27 pivotally movable by the striker resiliently to deform a resilient buffer when the striker and latch bolt are in their fully latching position. The member 27 is made of plastics and is mounted on a shaft 17 to which a pawl 19 for the latch bolt is secured and the resilient buffer 29 may be secured to a flange 30 on a cover plate 41. Alternatively the resilient buffer 129 is secured to a housing portion 115. The latch bolt 18 is mounted to pivot on a shaft 16 which has an enlarged portion 16a for engagement with an upper surface of the striker when in fully latching position. The latch bolt 18 is retained in a safety latching or fully latching position by the spring urged pawl 19 and is released by actuating a lever 33 pivoted to a cover plate 14 by operating an inside handle connected to a lever 37 at one end thereof or by an outside handle connected to the other end. The releasing lever 33 is pivotally connected to a link 35 whereby when the lever is actuated the link engages an end flange 38b upstanding on a control lever 38 pivoting on the shaft 17 and connected to the pawl by a projection 40 passing through an arcuate slot 42 in the cover plate 41. A locking lever 31 also pivoting on the shaft 17 is connected to the link 35 by a pin and slot connection and is actuated by an inside push button or an outside cylinder lock to rotate the end of the link 35 out of contact with the flange 38b so preventing release of the pawl from the latch bolt. Locking of the door before it is closed is cancelled by closing the door, the latch bolt causing the pawl to rotate and with it the control lever 38 causing a flange 38a thereon to strike the link 35 which rotates and pivots the locking lever 31 to the unlocking position. Keyless locking is effected by closing the door with both the latch releasing and locking levers actuated whereby the flange 38a is unable to rotate the link 35 and locking remains effective. A resilient buffer 43 on the housing portion limits rotation of the latch bolt.

Abstract: 977,657. Oil filters; gravity separation. C. H. MAY. Dec. 14, 1962 [Jan. 2, 1962], No. 47326/62. Heading B1D. In a filter-separator for removing solid and liquid contaminants from oil, contaminated oil is fed in by inlet 12, Fig. 1, to a first chamber 14, and passes down passage 41 provided in filter unit 40, which is surrounded by canister 38 and is located vertically in second chamber 50. Oil and contaminating liquid, i.e. water, flow radially out of the filter unit, which traps solid contaminants, and coalesces the water. Canister 38, the surface of which is hydrophobic, retains the water and allows oil to flow through into chamber 50, to be removed by outlets 60, 62 located adjacent opposite ends of the filter unit. Coalesced water descends to the bottom of the annular space between 40 and 38 and drains through opening 66 under the action of gravity, assisted by vacuum produced in chamber 32 and sump 36 by means of Venturi nozzle 30 fitted in the oil inlet line 12. If the oil contains little or no water, oil will collect in sump 36 and will be recirculated by the Venturi nozzle to chamber 14. Discharge of water is controlled by solenoid valve 82 actuated by conductors 84, 86. Alternatively a float valve may be used. A preferred filter unit comprises a perforated copper-silicon tube 42 surrounded by layers of moulded fibre-glass and acetate felt, contained by a knitted cotton sleeve. Canister 38 may comprise a 100-mesh screen of nickel alloy, rendered hydrophobic by a coating of polytetrafluoroethylene, and retained by an expanded aluminium mesh. Baffles 56 and 58 are provided at each end of canister 38 adjacent oil outlets 60, 62 to prevent coalesced water being drawn into the oil. A plurality of filter units may be provided in chamber 50, each receiving a flow of oil from chamber 14. Specification 821,877 is referred to.
