Patent GB-2117075-A (GB)
Title: Conduit coupling
Inventor: KORDULLA HANS
IPC: F16L27/08
Filed: 1983-02-24
Abstract: This conduit coupling allows rotary motion between two conduits so that, for example, a coolant may be conducted under high pressure through a gimbal to a gimbal- suspended infrared seeker head in a guided missile. The conduit coupling (18) is combined with a slip ring (10) for transferring signal and supply voltages. A coupling housing (20) includes a first conduit (22) terminated in a chamber (24). A coupling shaft (26), rotatably mounted in the housing, has a longitudinal bore (30). A capillary tube (32), forming a second conduit extends through the bore (30) and through a bore in a slip ring shaft (12) and is soldered to the coupling shaft. A seal with low friction and with a low leakage rate up to high pressures is achieved by means of a sealing element (34) within the chamber (24) the element being maintained in sealing engagement with the chamber wall by the fluid pressure. A precision bore (42) in the coupling housing ensures precise centering of various components of the coupling. A sleeve (54) couples the slip ring shaft (12) and the coupling shaft (26) and thus relieves the capillary tube (32) of mechanical strain. <IMAGE>

Title: Producing printed circuit boards
Inventor: ROBERTS DANIEL FRANK THOMAS
IPC: H05K3/04
Filed: 1983-08-23
Abstract: A method of producing printed circuits by selective vapour phase deposition of metal on an insulating substrate including the step of forming on the substrate prior to the metal deposition a mask layer consisting of a resist material having a porous structure with interconnecting pores opening onto the outer surfaces, such that the deposited metal thickness is insufficient to seal the openings in the resist material whilst the resist effectively prevents metal deposition on the underlying substrate. After the metal has been deposited the resist material is readily removed by the use of an appropriate solvent which, by virtue of the porosity of the resist material, will penetrate the resist beneath the metal coating.

Title: Producing corrugated thermoplastics sheet
Inventor: MARSHALL ROY WALTER
IPC: B29C53/84
Filed: 1983-09-16
Abstract: A method for producing corrugated sheet of a form in which the corrugations are made up of flat sections extending between discrete bends from flat thermoplastics sheet (10) involves heating the sheet selectively in a heating station (11) and subsequently bending the sheet in a bending station (21). Heating is effected by longitudinally extending heating elements (12, 13, 14 and 15) extending longitudinally along lines of desired bends. The heating elements are all arranged on the outside of the desired bend and the sheet is supported opposite each heating element by a support such as (16) which also acts as a heat sink. After indexing heated sheet to the bending station, it is bent by vertical movement of a male former (22) co-operating with a female former (23). The formed sheet is removed from between the formers after it has set to the corrugated form. The invention also extends to the apparatus employed. <IMAGE>

Title: Control system for an automatic continuously variable transmission for a vehicle
Inventor: HAYAKAWA YOICHI
IPC: B60W30/18
Filed: 1983-12-29
Abstract: A control system for a belt drive continuously variable vehicle transmission (CVT) comprises a downshift control mechanism 86 which controls the discharge of hydraulic fluid from a servomotor 530. The servomotor 530 operates to vary the effective diameter of the input pulley for the belt of the transmission and hence to vary the gear ratio. When the transmission is downshifted suddenly during acceleration (i.e. on 'kickdown'), the oil from the servomotor 530 can only escape through an orifice 87. This prevents too sudden a drop of hydraulic pressure in the servomotor 530, which would lead to slip between the belt and pulley and to a subsequent shock on take up. To ensure that the transmission downshifts fully when the vehicle comes to a stop, a solenoid valve 89 activates a downshift control valve 88 to allow hydraulic fluid to drain 9 to a drain put 883) more rapidly from the servomotor 530. The transmission control is electronic. A lock-up clutch of a torque converter in series with the belt drive is controlled in response to throttle position, input pulley speed and output pulley speed and the control includes a solenoid valve which is pulsed to control the rate of engagement. <IMAGE>

Abstract: An actuator cylinder for fluid power operation has a cylinder tube (26) with a piston (22) running therein, a cylinder cover (9) at one end of the cylinder and having an axially adjustable abutment member (4) therein surrounding the piston rod (1). Near the piston (2) there is a cushioning sleeve (3) which is engaged by a sealing ring (5) when it is moved into a cushioning chamber (14) inside the abutment member and around the piston rod (1). It is now not possible for fluid to flow out of the chamber past the sealing ring (5) and it is forced to flow instead through a choke duct (11) with an adjustable choke (13). This ensures that the impact of the piston (2) on the abutment member (4) is cushioned. <IMAGE>
Patent GB-2179899-A (GB)
Title: A velocity-differential steering system for four-wheeled vehicles
Inventor: CRABBE HENRY JOHN FREDERICK
IPC: B62D11/04
Filed: 1985-09-03
Abstract: A four-wheeled vehicle is arranged so that two power-driven wheels A1 and A2 are positioned to form a pair on an axis spanning the vehicle's width, with the other two wheels B1 and B2 comprising offset swivel-castors placed fore and aft of this axis and positioned on the vehicle's longitudinal centre-line. Wheels A are coupled together in such a manner that their relative rates of rotation are under control of the driver, who steers the vehicle by means of their velocity-differential, wheels B simply following the resulting direction of motion by castor action. Extreme manoeuvrability is achieved without any conventional mechanical steering system, including a facility for turning the vehicle on the spot about its own vertical axis C, while the scheme also lends itself to incorporation of a flywheel energy-storage device whereby rotational manoeuvres may be effected without the vehicle being otherwise powered. The wheels A may be driven from a single power source via a conical shaft D and slave wheels E; by variable pitch-circle diameter belt pulleys; by a pump and fluid coupling between the wheels, by differential gearing or by separate electric motors. <IMAGE>
Patent GB-2165108-A (GB)
Title: Motive power system
Inventor: TRUSOCK GEORGE JOSEPH
IPC: H02P5/685
Filed: 1985-09-13
Abstract: A traction drive system for a vehicle is disclosed which comprises a pair of series wound motors which are connected in series with each other and which drive independent traction wheels, respectively, of the vehicle. The no-load torque of each traction wheel is correlated with the transient torque characteristic of the motors so that each motor produces a transient driving torque greater than the threshold-load torque of the wheels. Further, each of the traction wheels and its respective drive gear train coupling it to a respective motor, have a sufficiently high moment of inertia and friction that motor speed at no-load is kept from reaching a value such that counter emf would reduce the transient driving torque below the threshold-load torque during a predetermined time interval. This arrangement permits one traction wheel to move the vehicle at low speed while the other traction wheel spins on ice or otherwise fails to exhibit tractive effort.
