Patent GB-2014153-A (GB)
Title: Foamed ethylene copolymer articles
IPC: C08J9/12
Filed: 1979-01-03
Abstract: Articles having a closed cellular foam structure are made from an ethylene copolymer having up to 45% by weight of comonomer and which contains 0.2 to 6% by weight of a cross-linking agent. The article is made by (a) moulding a cross-linkable composition comprising the copolymer, which is then (b) cross-linked and (c) removed from the mould. A physical foaming agent, e.g. CO2 or nitrogen, is diffused at high pressure into the cross linked preform and then this pressure is removed. This expands the foaming agent to produce the closed-cellular foam. The final article has bulk density 0.01 to 0.5 g/cm<3>. Preferably 95% of the cells have a diameter below 0.8 mm with most cells having diameters of 0.01 to 0.1 mm. Preferred copolymers include vinyl acetate and methyl ethyl or butyl esters of acrylic and methacrylic acids.

Title: Ultra-narrow connecting leads for liquid crystal display
IPC: G02F1/1345
Filed: 1979-04-20
Abstract: A liquid crystal display having extremely narrow electrode connections 66 between the character segments 62 and the termination pads 64 to eliminate backplane patterning and alleviate the critical alignment between the opposing electrodes on the two plates.

Title: Archery bows
IPC: F41B5/18
Filed: 1979-07-21
Abstract: An attachment for an archery bow comprises a strut having a catch mechanism at one end thereof for releaseably connecting the strut to the stock of a bow, and a trigger mechanism at the other end thereof for releaseably engaging the bow string.
