Patent GB-2050209-A (GB)
Title: Means for restraining movement between relatively displaceable members
IPC: B25B5/16
Filed: 1979-02-28
Abstract: The invention is based upon an appreciation of the vernier scale system of measurement to provide locking between two members, one of the members having a series of equally spaced locking elements and the other member having a series of equally spaced recesses, the spacing between the locking elements being nearly, but not quite, equal to the spacing between the recesses so as to provide a number of closely spaced locking locations. The invention is particularly suitable for use in vices, chucks for lathes and other clamping devices.

Patent GB-2067303-A (GB)
Title: Method for manufacturing an electrochromic display cell and an electrochromic display cell
IPC: G09F9/30
Filed: 1980-11-26
Abstract: An electrochromic display cell comprises a frame interposed between an ionic conductor and an annular soldered zone sealing a cover of the cell to a substrate of the cell. The frame is squeezed between the cover and the substrate to tightly separate the ionic conductor and the solder, preventing any reaction therebetween. In a preferred embodiment, the frame is made of a thermofusible material. It partially melts during the sealing of the cell, adhering thus very tightly to the cover and to the substrate.

Title: Method of processing end portions of covered wires in a wire harness
Inventor: SUZUKI YOSHITSUGU
IPC: H01B13/012
Filed: 1982-03-04
Abstract: A covered wire 8 is held at a position spaced from its free end by a holder 83 and is nipped from above and below by a pair of cutting edge members 104 and 104' (Fig. 24-B). The members 104, 104' are then moved away from the holder 83 to a first position (Fig. 24-C) where they cut an insulating covering 8a of the wire 8. Thereafter, the members 104, 104' are moved further away from the holder 83 to a second position (Fig. 24-D) where they cut the conductor of the wire 8. This latter movement of the members 104, 104' causes the insulating covering 8a to be stripped from the conductor over a portion corresponding to the first position to the second position. <IMAGE>
