Title: Glass-flake reinforced reaction injection moulded polymer panels
Inventor: KOSTECKI RAYMOND JOSEPH
IPC: B29C70/26
Filed: 1983-02-18
Abstract: The physical properties of reaction injection moulded (RIM) polymeric panels are substantially improved by internally reinforcing them with flake glass filler particles. The flake glass is incorporated in the liquid chemical polymer precursors, and is co-injected with them into the mould. The flow of the liquids in the mould orients the glass flake to provide maximum improvement in physical properties in the hardened polymerized panel, the panel thus having a reduced coefficient of thermal expansion as compared to a like unfilled article. Moulding with glass flake filler also substantially alleviates problems of surface waviness in RIM panels. The panels may be automotive body panels.

Patent GB-2151406-A (GB)
Title: Electrical accessories
Inventor: CLIVES STANLEY WILLIAM
IPC: H01H73/38
Filed: 1984-12-06
Abstract: A switched electrical accessory has an operator (16) for its normal contacts (12) and a further contacts 20 made and broken by a switch member (22) according to whether or not its associated latch (28) engages another member (36). The member (36) and the switch member (22) have opposing relatively strong and weak biasing springs (38 and 24), respectively to assure their separation and break action of the switch member (22) at latch disengagement. Re-engagement of the latch (28) is by movement of the member (36) first against its bias (38) to pick up the switch member (22) and then by its bias (38) to overcome the other bias (24). That re-engagement movement is by operation of the operator (16) beyond its normal ON position. Tripping of the latch 28 by a circuit condition sensor coil releases contacts 20 to be opened by springs 24 and also releases member 36 which is then driven by the spring 38 to act on the operator 16 to open the contacts 12. <IMAGE>
