Patent GB-2185526-A (GB)
Title: Door closure mechanism
Inventor: SULLIVAN ANDREW
IPC: E05B17/00
Filed: 1987-01-22
Abstract: The mechanism comprises spring-loaded pulling means (4,5, Figure 1) adapted to be mounted on one of a door panel (2) and frame (1), and a latch member (7) for mounting on the other of the panel and frame. The latch member (7) is adapted for engagement by said pulling means (4,5) so as to assist in the final stage of door closure. The arrangement is such that withdrawal of the latch member (7) on opening of the door (2) resets the spring-loaded pulling means (4,5) for the next closure operation. Alternatively, a door-mounted, spring-biased jaw (115, Figure 4) is held open by a retractable detent (116). With door closure, a jamb-mounted, fixed head cams the detent to retract, and the jaw is spring-urged to engage behind the head and close the door. A bolt (108) is urged through a hole (117) to lock the jaw and the door. The bolt may be retracted by a twist handle (123), a rocker plate (129) or a push button (130). Door opening re-pivots the jaw (115), and allows the detent (116) to extend to hold the jaw against its spring bias. <IMAGE>

Title: Machining of workpieces made of brittle materials
Inventor: HINZEN HUBERT
IPC: B24B7/04
Filed: 1987-05-19
Abstract: A process and apparatus for machining the plane-side-transverse grinding of a workpiece surface using a grinding wheel (1) rotating about a first axis at a first rotational velocity wherein the workpiece (3) or the grinding wheel is rotated about a second axis parallel to the first axis but displaced from it at a second angular velocity equal to the first angular velocity.

Title: Packages having tactile orientation indicating means
Inventor: MARTIN CHRISTOPHER PAUL
IPC: A61F6/00
Filed: 1990-10-30
Abstract: Packages 1 having a symmetry which does not readily reveal their orientation and more particularly that of their contents have on an outer surface tactile indicia of their orientation and thereby of their contents. The indicia in the form of a grit-containing ink or glue pattern are particularly useful for establishing the orientation of the contents of packages in the dark or in poor light conditions, and by people with visual handicap.
