Title: Process for producing plastics foil
Inventor: PREDOHL WILLI
IPC: B29C48/92
Filed: 1993-06-21
Abstract: A process for producing and winding into a coil a plastic foil which as produced, has a thickness error profile across its breadth comprising systematic positive thickness errors and/or systematic negative thickness errors wherein the thickness error profile is adjusted as the plastics foil is coiled to produce a coil of sufficiently exact cylindrical profile by measuring the thickness error profile and feeding the results to a computer which determines necessary correction values such that the thickness of the plastics foil is increased over at least parts of the zones between the error zones having positive thickness errors, in proportion to those positive thickness error values. This plastics foil having zonally increased thickness is wound on until the growing coil acquires an adequately cylindrical contour, and the cycle of operations as above described is repeated until the complete coil of adquately precise cylindrical contour has been wound.

Title: Method of determining the direction to a communications satellite
Inventor: FELDMAN HOWARD
IPC: G01C1/00
Filed: 1994-06-07
Abstract: The direction of a defined position, such as that of a geostationary communications satellite, from a variable position P<1> within a specified area is found using a map projection of the area with a point S<1> to represent said defined position. The map has a reference direction for azimuthal orientation and points on the map represent positions in reality such that azimuthal position reference directions from each position in reality to a single reference position are parallel to said map reference direction and a map bearing from a point P<1> to the point S<1> equals, within limits, the bearing in reality. The distance on the map between points P<1> and S<1> is related to the elevation of the satellite. The method can also be used to find the direction of Mecca. A map holder with a compass and a pivoted pointer carrying a slidable indicator is also described (Fig. 4). <IMAGE>

Title: Apparatus and method for vehicle suspension caster angle control
Inventor: HARARA MITSUHIKO
IPC: B60G7/00
Filed: 1994-06-16
Abstract: Operation of actuators are controlled in response to inter alia a steering wheel angle  theta h, a steering wheel angular velocity ( theta hs Fig. 11), and a road surface ( mu ), in addition to a vehicle speed Vel, to change a caster angle. The caster angle is increased to increase a righting moment of vehicle wheels during steering. The caster angle is increased according to the vehicle speed Vel in non-steering and initial steering conditions, to stabilize the vehicle. The caster angle of the wheel is set to a desired value by the actuator 7L, 7R which is supplied with fluid from source 9 controlled by electromagnetic valve 8. Furthermore, the control means 10 calculates a steering angular velocity correction amount according to an additional coefficient based upon the vehicle speed and road surface frictional coefficient and corrects the target caster angle according to the generated steering angular velocity correction amount. Also, control means having a plurality of control modes having different control gains to control operation of the actuator means is taught. <IMAGE>

Abstract: A coupling, eg for a limited slip differential of a four wheel drive vehicle, comprises a disc 41 which rotates in a chamber 40 filled with a viscous fluid and has in its surface spiral grooves 45, 55 which upon relative rotation between hub 36 and housing 35 generates, as a result of shearing forces in the fluid, a pressure and a volume flow. The pressure may be applied to a piston 37 which operates a friction clutch (32, fig 3) having outer and inner plates (33, 34, fig 3) non-rotatably connected to the housing 35 and hub 36 respectively. Alternatively the change in pressure or volume may be utilized in a viscous coupling (72, fig 14), having an annular piston (79, fig 14) and a compensating chamber (92, fig 14), so as to increase/decrease the distance between its plates (73, 74, fig 14). The grooves 45, 55 are connected by axial bores or recesses 49 which convey fluid from one groove to the other and a reservoir in the form of an annular groove 48 is also provided. Springs (eg 51, fig 6) and various other methods (see figs 6 to 12) may be employed to alter the coupling characteristic and/or to compensate for changes in fluid volume etc due to, for example, temperature effects. <IMAGE>

Patent GB-2298945-A (GB)
Title: Traffic light control systems
Inventor: LUX LAWRENCE JOHN
IPC: G08G1/08
Filed: 1993-12-17
Abstract: The system has moving vehicle detectors which govern the changeovers between red and green in accordance with traffic flow, giving a minimum green period to a detected vehicle, which may have to be delayed while an opposed green period expires and an inter-green time elapses. A leading vehicle may fail to respond promptly to a facing green and the minimum green time may then expire with no traffic flow. But vehicles moving up briefly behind the leading one will signal that a queue has formed and the minimum green time will be extended to give the queue a further chance of moving. No detection of movement during a green period will cause opposed lights, if they have been primed by an approaching vehicle, to turn green for a period before another green period is automatically granted to the original lights.
Patent GB-2300849-A (GB)
Title: Communications System
Inventor: LEWIS DAVID LLEWELLYN
IPC: B66B3/00
Filed: 1996-07-19
Abstract: A communications system (Figure 1) e.g. for an elevator includes local modules (8) at each landing of the elevator. Each local module has an integral announcement device including a LED display (12). External announcement devices such as hall lanterns (13) and arrival gongs (14) may also be connected to each local module. The local modules are served by a two wire power bus (6) and the announcement and display information provided by the local modules and announcement devices is controlled by a master control unit (5) which encodes signals to the local modules using pulse code modulation of the power supplied via the bus. The communications system enables the wiring loom of an elevator to be simplified since only two wires are required in the bus for the purpose of both supplying power and control signals to the local modules. Preferably, the master control unit modulates the power by interrupting the power supplied by the bus for a variable period which minimises data corruption when decoding the signal at the modules as both conductors are at the same reference voltage e.g. ground. The communication system can also be used for public service transport systems such as trains or monorails.
