Patent GB-2140216-A (GB)
Title: Prime movers
Inventor: WEUN HORNG-ING
IPC: F03B13/24
Filed: 1983-05-16
Abstract: A prime mover for a land or water vehicle comprises several or more pumps driven by the shock force of vehicle wheels or by the surging force of a water wave for compressing air into an air tank 31, and a mechanism 10 furnished with permanent magnets 70, 70' and 8a. By means of the repulsive force between the permanent magnets, the linear motion output of one or more double-acting cylinders 5a, 5b, 5c driven by the compressed air from the air tank 31 can be converted into rotary motion output. <IMAGE>

Patent GB-2147311-A (GB)
Title: Electrodepositing precious metal alloys
Inventor: O'HARA JAMES BRIAN
IPC: H05K3/06
Filed: 1983-09-29
Abstract: A method of electrodepositing an alloy of a precious metal, which comprises electrodepositing a first layer with a first precious metal content from a first plating bath and thereafter electrodepositing a second layer with a second precious metal content directly on to the first layer from a second plating bath, the first and second baths being compatible such that no intermediate treatment e.g. rinsing of the first layer is required before applying the second layer from the second bath. The method may be used in the manufacture of printed circuits. For example, a Pd-Ni alloy may be electrodeposited by depositing a first 4 micron thick layer of 20/80 or 10/90 Pd/Ni followed by a second 1 micron layer of 90/10 Pd/Ni without any intermediate treatment. The method may also be used in the manufacture of jewellery or costume jewellery. For example a first gold alloy layer relatively poor in gold may be directly followed by a thin rich gold alloy or pure gold layer. Further applications of the invention are in the plating of electrical conductors and in electroforming.

Title: Opening roofs for vehicles
Inventor: FISHER SIDNEY EDWARD
IPC: B60J7/16
Filed: 1984-06-01
Abstract: A sun blind for an opening roof for a vehicle comprises an opaque panel 22 dimensioned to cover at least a substantial part of the opening.

Title: Improvements in utility knives
Inventor: GILBERT RICHARD
IPC: B26B5/00
Filed: 1987-05-08
Abstract: PCT No. PCT/GB88/00342 Sec. 371 Date Jan. 8, 1990 Sec. 102(e) Date Jan. 8, 1990 PCT Filed Apr. 29, 1988 PCT Pub. No. WO88/08775 PCT Pub. Date Nov. 17, 1988.A utility knife comprises a lower elongate part shell 1 and an upper such part shell 3 forwardly fitted with interengaging wedging surfaces whereby they clamp together on relative longitudinal movement. This movement is achieved by turning nut 2 on shank 8 to bear on wall 30. The loosening of the nut 2 to unclamp the part shells and thus permit blade 43 to be pushed forward with slider 42 by pushbutton 41 does not separate the part shells 1 and 3 since the end spur 9 of the shank 8 still rides on arresting web 37. Maximum unscrewing of the nut, however, permits separation e.g. for access to stack of spare blades 60 resiliently held at 59 in the rearward part of shell 1 (now unencumbered by the conventional screw-shank), but does not lead to loss of nut 2 because of a complementary detent configuration 25 at the end of the shank and in the end wall 2a of the nut prevents complete nut/shank separation. Spur 9 can be upwardly sloping at its underside and thus constitute an auxiliary clamping means for part shell 1 against part shell 3.

Title: Windscreen wiper operating mechanism
Inventor: BAYNHAM DAVID
IPC: B60S1/34
Filed: 1988-02-18
Abstract: In a windscreen wiper arrangement comprising wiper 60 mounted on arm 52 connected to drive shaft 51 of wiper motor 50, the wiper is rotated about the axis of arm 52 by another motor 54 via transmission gearing 55, 56, 58, 59 whilst it is moved to and fro across windscreen 61. The wiper may be a conventional wiper blade, or cylindrical structure with radially-extending blades, or a bristled brush. In other embodiments, the wiper is not rotated about the axis of the wiper arm, but wiper and arm are subjected to an additional motion during the course of normal to and fro movement. This may be effected by imparting a rocking motion to a pivotally-mounted drive motor, or by linearly displacing a drive motor against the bias of springs, or by vibrating the drive motor. Improved cleaning action is said to result. <IMAGE>
