Patent GB-2242166-A (GB)
Title: Pressurised air system to improve driving visibility
IPC: B60S1/54
Filed: 1990-03-23
Abstract: A pressurised stream of air is created inside a vehicle using a compressor. The air is then forced through a tube from the compressor to the outer body of the vehicle. The tube or channel then runs along the outer shell of the vehicle. Along this length, at certain points, a series of nozzles are placed so that the air can escape, (still under pressure). By placing the nozzles fairly close together a 'curtain' of air is then produced. The purpose of this arrangement is to deflect snow, rain and other 'foreign bodies' from the vehicles wind-shield and thus increase the drivers general visibility. <IMAGE>

Title: Improvements relating to movement actuators
Inventor: EDWARDS ERIC FRANK RHYS
IPC: G01B7/16
Filed: 1990-11-15
Abstract: An actuator for a joint comprises a bladder-shaped chamber (5) whose one end is secured to an arm (2) by a mounting (6), whilst a bundle of fibres (7) extend from the other end of the chamber member (5) to a junction (8) on another arm (3).

Title: Manufacturing thin plates having surface structures of different depths or heights
Inventor: SAAMAN ARY
IPC: H01L21/308
Filed: 1991-04-15
Abstract: A silicon wafer (2-8) having surface structures of different depths or heights on one or both sides, e.g. for use as an integral part of a micropump is produced by a particular process. In order to reduce the number of photolithographic steps in a production process requiring several etching or growing steps, the starting wafer (3) comprises a central layer (8) which is covered on both sides with oxide layers (9a, 10) of different thicknesses. In a first process phase both oxide layers (9a, 10) receive surface cavities (12, 12a) which, on the side of the thinner layer (9b) completely traverse the latter, whereas they do not reach the central layer (8) on the side of the thicker oxide layer (10a). While a first etching or growing operation on the central layer (8) is carried out on the wafer (5) which only affects the side of the central layer (8) which carries the thinner layer (9a) while the other side is still entirely covered by the thicker layer (10a, 10c), the second etching or growing step on the central layer (8) is carried out after the thicker layer (10a) has been reduced such as to expose the central layer (8) at the initially formed cavities (12a). Thus, the depressions (14) formed at the side of the initially thicker oxide layer during this second etching step on the central layer are less deep, or in the case of a growing process the first deposits are less high than the depressions (13) or deposits formed on the other side during both etching or growing steps.

Title: Cash control and replenishment of automatic teller machines
Inventor: SANO MASAHIKO
IPC: G06Q20/18
Filed: 1991-05-31
Abstract: Card or bankbook actuated teller machines (3A, 3B, Figure 1) automatically execute cash depositing/drawing transactions, a teller machine controller (1A, 1B, Figure 1) electrically communicating with the teller machines to control them, store currency data, and initiate automatic replenishment of paper currency. Each teller machine is provided with currency storing units 604, 605 for storing different value paper currencies and a replenishing currency storing unit 606. The teller machine controller receives currency data relating to the amount of the paper currencies stored in the currency storing units 604, 605 and stores the data in a memory. The teller machine controller automatically decides whether the currency storing units (604, 605) should be automatically replenished from the replenishing storing unit 606 based on the currency data. The condition of each storing unit can be displayed on a panel of the controller, card accessed by a service operator, the operator then performing auxiliary manual currency recovery and replenishment if necessary. Currency deposited by a user into inlet 25 passes to validatory unit 608, and if valid along path 610c to an appropriate unit. If the deposited currency is invalid or abnormal it is returned to outlet 25 via wheel 613. If a user wishes to withdraw currency it is removed one note at a time from the appropriate storing unit and passed to outlet 25 after collection in stack form at P. <IMAGE>

Title: Remote switch to host switch signalling in telephone systems
Inventor: PINARD DEBORAH L
IPC: H04Q3/60
Filed: 1992-06-24
Abstract: A host routing code is transmitted from a remote switch 1 to a host switch 2 which advises the host switch 2 whether a call is to be made to a subscriber local to the host switch or to a remote subscriber via an external telephone system trunk connected to the host switch. The remote switch 1 appears to a subscriber connected thereto, when dialling, as if it were the host switch 2, and numbers dialled are the same. In the set up of a call, two steps are executed in addition to those of a normal switch-to-switch communication which functions to set up a path from the remote switch through, or to the host switch. These steps are the outpulsing of a host routing code, from a remote route assignment form in the remote switch, over a specified trunk to the host switch, and waiting for an acknowledgement such as a wink (temporary line open or close condition). The host routing code causes the host switch to set up a cut-through path through the host switch, allowing the remote switch to tandem through the host switch. The digits dialed by subscribers on both switches for similar types of calls are the same, and similar types of switches can be used for the remote and host thus reducing cost. <IMAGE>

Title: A fail safe flexible coupling having a membrane with a large spoke lenght
Inventor: GREY JOHN CONSTANTINE
IPC: F16D3/79
Filed: 1993-08-04
Abstract: A flexible membrane has bolts 11, 12 placed in windows so that the spokes effective length 13 is increased and upon the spokes failure no torque is transmitted by the bolts. The membrane or membrane pack is clamped at its outer annulus 8 between a coupling hub and clamping ring 14 and at its inner annulus 10 between ring 15 and drive ring 16. Tightening the bolts 11, 12 generates friction at the inner and outer annuli 9, 10 so that torque is transmitted. A spacer 17 is spigotted and bolted to drive ring 16 and is removed by axially forcing ring 15 against the hub face thus releasing register 18 from ring 16. Ring 15 may be disposed of and the membrane/membrane pack welded, eg laser or electron beam, directly to the drive ring (22, fig 7). Outer annulus 9 may be discarded and the spokes clamped between ring (30, figs 7 and 8) and hub (33, fig 7), thereby reducing clamping stresses. <IMAGE>
