Title: A Speed Control Device
IPC: F16H15/38
Filed: 1978-12-15
Abstract: Plates (19, 16) with opposed annular grooves (22, 21) forming a toroidal track for rollers (23) are mounted for rotation with concentric shafts (6, 8) which emerge from one end of a fixed housing (1). The plate (19) is capable of axial displacement (through splines 20) relative to its shaft (6) by spring biasing (32). The plate (16) is capable of axial displacement (through splines 17) relative to its shaft (8) by fluid pressure in chamber (38) controlled by a valve (41) actuated by a governor (42) driven by the shaft (8). Axial displacement of plate (16) causes carriers (27) for the roller (23) to pivot about (28) to change the transmission ratio. The splines (17, 20) are helical so that the plates (16, 19) are urged axially into driving engagement with the rollers (23) by torque which is imparted to the plates (16, 19) by their driving engagement with the rollers (23). In a modification the centrifugal governor (42) and valve (41) are omitted and the chamber (38) is responsive to fluid pressure derived directly from a variable delivery pump driven from the shaft (8). <IMAGE>

Patent GB-2017252-A (GB)
Title: Vehicle Clutch Control
IPC: F16D48/02
Filed: 1979-02-28
Abstract: Apparatus for controlling the engagement of a vehicle clutch operates during the connection of the vehicle drive to a power take-off unit (54). Such connections can result in damage if an operator engages the clutch too quickly. The present invention overcomes such a possibility by throttling the release of fluid pressure to control the rate of engagement of the clutch, the pressure being initially used to extend a cylinder (38) against a restoring force, to thus disengage the clutch, when pressure is supplied to engage the power take-off (54). <IMAGE>

Patent GB-2033602-A (GB)
Title: Dichroic liquid crystal displays
IPC: G02F1/1337
Filed: 1979-10-09
Abstract: In a dichroic dye guest-host liquid crystal display cell, the boundary conditions at the opposed surfaces of the liquid crystal layer are established such that molecules 65, 66 adjacent to one surface are parallel to the surfaces and molecules 65a, 66a adjacent to the other surface are perpendicular to the surfaces in either of the light transmissive or light absorptive conditions, thereby reducing light absorption at the boundaries in the (energised) light- transmissive condition. Absorption in the unenergised condition may be increased if the liquid crystal contains a chiral dopant, which tends to reduce the tilt of the molecules in the bulk of the layer relative to the surfaces. <IMAGE>

Patent GB-2048688-A (GB)
Title: Programmable demand pacer
IPC: A61N1/372
Filed: 1978-11-16
Abstract: An implantable R-wave inhibited cardiac pacer has integrated digital logic circuits including programmable registers 12, 16 (210, 262, Fig 4) to determine the pulse rate and width. A 5-3-4 code applied by an external pulsed electromagnet to a reed switch 20 (400, Fig.5) unlocks a digital lock 18 so that rate register 12 can be reprogrammed to any value between 30 and 120 BPM. A 5-3-2 code allows the width register 16 to be reprogrammed, and the circuitry ensures that the programmed width can only lie between set limits. If a main timing circuit failure gives rise to a rate above 130 BPM, a protection circuit 32 feeds pulses to the heart 36, at half the rate from generator 28. A refractory circuit 42 prevents the generator being reset by a heart signal for 256 or 320 msec following a sensed natural beat or a pacing pulse respectively, noise sensing circuits operating from the last 64 msec of the refractory period, and the paceroperating uninhibited at its programmed rate in the presence of noise. Closure of switch 20 by a permanent magnet causes uninhibited operation at 100, 90 or 85 BPM depending on whether the battery is new, half-discharged or should be replaced, the pacer giving six uninhibited pulses at the programmed rate on removal of the magnet. The disclosure is the same as that in G.B. Specification No. 2,014,858A. <IMAGE>

Title: Coin-operated switch device
IPC: G07F15/12
Filed: 1981-02-10
Abstract: In a coin-operated apparatus, a coin inserted at 20 falls down passage 13 to a position between projections 33, 34 projecting from the face of an aluminium disc 30. The coin is supported by a raised portion 35 of a support board 12 and loosely retained against sideways escape by a spring 41. In this position the coin moves a lever 54 which actuates one or more switches (51, 52, Fig. 2 not shown). One switch actuates the apparatus and the other slowly rotates disc 30 in the direction of arrow 36 so that after a predetermined period of time the coin is displaced out of the switch- actuating position against the resistance of spring 41. The coin then drops out of the mechanism. The period of time may be adjusted by varying the position of one or more of the projections 33. The passage 13 may store a plurality of coins for continuous operation of the switches, the next coin falling under gravity to replace a coin displaced by projections 33. <IMAGE>

Patent GB-2082266-A (GB)
Title: Driving mechanism for fuel injection pumps
IPC: F02M59/20
Filed: 1981-07-30
Abstract: The driving mechanism comprises a rocker arm (4) for actuating, via a tappet 12 a piston rod and piston of the pump. The rocker is mounted on an eccentric shaft (7) which is rotatable by a special drive (not shown) for the purpose of adjusting the timing of the injection pump.   The pump is operated by a camshaft (3) driven by the engine and has in addition to a fuel injection cam lobe (2) one or more auxiliary cam lobes (13, 14) which merely give the rocker arm (4) a slight swivelling movement but do not cause fuel injection. Normally a large torque is required to rotate the eccentric shaft (7) to adjust the pump timing in operation but the addition of the auxiliary cam lobes (13 14) give a continuous swivelling movement to the rocker arm (4) during the adjusting process so that only sliding friction between the arm (4) and the eccentric shaft (7) has to be overcome, thus reducing the torque required for adjustment. The height of the auxiliary cam lobe is not more than one fifth of the height of fuel injection cam lobe. <IMAGE>
Patent GB-2086501-A (GB)
Title: Wear indicator
IPC: F16D66/02
Filed: 1981-10-13
Abstract: A device for indicating wear of a consumable material, such as a drum brake lining or clutch plate comprises a support member (12) having a head (18) located within the depth of the consumable material. An insulated conductor (30) is associated with the support member (12) and extends across the head (18) thereof, the insulating material being no more resistant to wear than the consumable material. In use, as wear of the consumable material occurs, the insulating material is exposed to an abrading surface (e.g. of brake drum) causing the wear of the consumable material so that the insulating material is itself worn away so as eventually to expose the conductor. When the conductor is exposed, an alarm signal is generated. Preferably a further alarm is generated when the conductor is completely worn through. Support member (12) is secured in position by circlip, barb fixing washer or, as shown, has a screw threaded portion (16) engaged by nut (48) to retain member (12) on a brake shoe. Conductor (30) is retained in position by a washer (34) (see also Figures 4, 5) or a washer (52) (Figures 6-8). <IMAGE>

Title: Pilger rolling of tubes
IPC: B21B21/00
Filed: 1981-12-07
Abstract: The invention relates to pilger rolling, and to a method and apparatus which enable constant monitoring of the rolling rate and adjustment thereof to optimum values to ensure maximum efficiency of operation of the mill. The forward movement of a rolled blank is measured in at least one monitoring section (X1) downstream of a pilgering section (Y). This movement is correlated with the number of strokes of the pilger rolls (4) to determine the rolling rate. The rolling rate can thus be continually adjusted (automatically or manually) to an optimum pre-set value. <IMAGE>
