Patent GB-1134216-A (GB)
Title: Improvements relating to control systems for fluid-flow-regulating valves
IPC: F16K1/44
Filed: 1965-11-25
Abstract: 1,134,216. Valves. REAVELL-FAHIE Ltd. 25 Nov., 1965 [12 Dec., 1964], No. 50180/65. Addition to 1,064,816. Heading F2V. [Also in Division G3] The apparatus controlling fluid flow described in the parent Specification now employs an electromagnetically actuated valve in which the actuator comprises an armature bar 12 which is coupled to the valve spindle 4 by a concave/convex seating 11, 9 to facilitate alignment, the joint being held together by a screw cap 13 and clamp 14. The clamp also carries a member 15 which is connected to a return solenoid 21. There may be an oil damper (not shown).
Patent GB-1479750-A (GB)
Title: Torque converter transmissions
IPC: F16H47/08
Filed: 1974-11-20
Abstract: 1479750 Change-speed gear GKN TRANSMISSIONS Ltd 12 Nov 1975 [21 Nov 1974] 50415/74 Heading F2D A hydrodynamic torque converter comprising at least three elements is combined with three epicyclic gearsets each consisting of an annulus or ring gear, a sun, and a carrier with two or more planets, a first of the gearsets having two of its members directly connected to two elements of the converter for controlling the performance of the latter, the second and third gearsets providing forward/reverse drive and high/low range, all of the suns being coaxial, and corresponding members of each gearset having the same number of teeth on the same pitch circle diameter. In one arrangement the ring gear 19 of the first gearset is connected to the reaction member 16 of the converter and the sun 20 is connected to turbine 15. The planet carrier 22 may be braked so that the reaction member is driven backwards to provide low range, the ring gear and reaction member may be braked to establish intermediate range, or the turbine may be clutched to the input 17 for direct drive or high range. The turbine drives the sun 23 of the second gearset of which the carrier 32 may be clutched to the sun or braked to impart forward or reverse drive to the ring gear 24 which has a direct connection with the ring gear 25 of the third gearset, the carrier 30 of the latter constituting the output member and low or high range being established by braking the sun or locking the train by clutching the sun to the ring gear. In a modification the sun of the first gearset is connected to the impeller instead of to the turbine, whilst in another arrangement the turbine is connected to the carrier of the first gearset, the reaction member is connected through a one-way clutch to the sun, and the ring gear provides the input to the second gearset. This arrangement provides only two ranges for the converter/first gearset combination, as does another arrangement in which the first gearset precedes the converter, the input being connected to the carrier, the ring gear to the impeller, the sun to the turbine which provides the input to the second gearset, and the reaction ring having a one-way clutch connection with a fixed part of the apparatus. A further modification of the converter/first gearset combination, providing three ranges, has a converter with two reaction members one of which is connected through a one-way clutch to a fixture and the other to the sun of the first gearset, the impeller is driven directly by the input, and the turbine is connected to the ring gear and provides the input to the second gearset. In all of these modifications, and also in other known converter/first gearset combinations which are illustrated, including two with two turbines, the arrangement of the second and third gearsets is unaltered. The brakes and clutches are multiplate units actuated hydraulically.

Abstract: 1408597 Fluid pressure servomotor systems DANFOSS A S 2 Nov 1972 [16 Nov 1971] 50553/72 Heading G3P [Also in Divisions B7 and F2] A valve suitable for use in a vehicle steering system has an e.g. rotary cylindrical closure member 1 connectable to a steering wheel and a seat 2 connectable to a feedback motor which moves in one direction or the other when ports 6 or 7 are pressurized via ports 3 and grooves 4, 5 upon rotation of member 1 from a neutral position in which bypass ports 9a-9c (of which there are e.g. 18, 12 and 6 respectively) in the seat align with drain ports 8 in the member 1, the arrangement being that, upon rotation of member 1, firstly ports 9a move out of register with their associated ports 8, then ports 9b and finally ports 9c, thereby providing a desired bypass - displacement characteristic. The by-pass circuit is preferably still open when grooves 5 start to overlap ports 6 or 7. Ports 8 associated with ports 9b, 9c communicate with an annular chamber 11 have sound-damping discharge orifices 12. In a modification, the chamber 11 is integral with member 1 and fluid escapes around a split spring ring into the bore of the member. The ports 6, 7 may be connected to exhaust via a similar arrangement of grooves and ports 3-5. The feedback motor receiving the fluid from the valve may meter that fluid to an hydraulic actuator controlling a steering mechanism. The same porting arrangements can be provided for valves with flat and linearly slidable members.

Abstract: 1450962 Releasable fastenings BUNKER RAMO CORP 31 Oct 1973 [28 Nov 1972] 50643/73 Heading E2A [Also in Division H2] A two-part coupling comprises a heat-activatable locking member 25 disposed in a cavity 46 formed between the coupling parts when they are coupled, the locking member changing shape in response to the application of a predetermined amount of heat to bear against the cavity surfaces and rigidly lock the parts together. The locking member 25 is a ring of a memory alloy of nickel and titanium of a shape which changes from that shown in Figure 1 to that in Figure 5 when heated, retaining the changed shape when allowed to cool. The coupling parts 12, 14 are held together by a screw ring 16 rotatably mounted by a washer 36 on the part 14, and include an O-ring 31 and one or more contacts 26, 28 mounted in insulating bodies 22, 24 within shells 18, 20, opposed annular surfaces 42, 44 of the shells forming the cavity 46. The ring 25 has serrations (25a, Fig. 2) for engaging the cavity surfaces and tabs 25b to provide visual indication of the shape of the ring. Application of cooling causes a return of the ring shape to that in Figure 1. A further embodiment (Figs. 6-10, not shown) comprises a bayonet action coupling with the locking member having the general form of a wave washer.

Abstract: 1364099 Semi-conductor bodies DOW CORNING CORP 3 Nov 1971 [7 Dec 1970] 51035/71 Heading C1A Solid bodies of semi-conductor material, e.g. Si or Ge rods, are prepared by passing a stream of gas or gas mixture, which forms the semiconductor material on heating, into the interior of a heated hollow body whereby the body is gradually built-up therein. A cylinder 11 of, e.g. quartz, carbon, tantalum, silicon carbide, molybdenum, tungsten or stainless steel may be closed by slice 12 of semi-conductor material, e.g. silicon or graphite. A gas injection lance 16 may be used to supply a stream of a gas, e.g. HSiCl3 or SiH4/H2 mixtures, into the cylinder and against the closure 12 heated in furnace 14. The lance may be withdrawn as the semi-conductor material builds up in the tube. The cylinder may have been formed by depositing the cylinder material on to a mandrel of, e.g. tantalum or graphite, and then removing the mandrel. The inside surface of the cylinder prior to formation of the rod may be coated with silicon, alternate layers of silicon and silcon oxide, silicon carbide, a layer of silicon oxide on a layer of silicon carbide or alternate layers of silicon and silicon oxide on a layer of silicon carbide. The silicon carbide layers may be deposited by either decomposing a gas e.g. (CH3)2SiCl2 or by melting a layer of Si deposited on a layer of graphite. The alternate layers of Si and silicon oxide may be prepared by partially oxidizing a layer of Si, followed by further deposition of Si.
