Abstract: Disclosed is a molded disc useful in optical information recording carriers, the disc is comprised of a copolymer of methyl methacrylate and ethyl acrylate, wherein the copolymer is comprised of 97 to 99.9 wt. % of methyl methacrylate and 0.1 to 3 weight % ethyl acrylate, has a molecular weight in the range of from 90,000 to 115,000, has a Tg of from 105° C. to 115.

Abstract: The invention relates to a process for preparing molded discs suitable for use in optical information recording carriers and to the optical information recording carriers thereby obtainable. The process comprises plasticating a homopolymer or a copolymer of methyl methacrylate, injecting the plasticated homopolymer or copolymer into a mold to form a disc and removing the molded disc in a very short cycle time. Good quality discs which are particularly suitable for use in optical information recording carriers may thereby be obtained.

Abstract: A battery attachment apparatus (201) for attaching a battery (200) to an electronic device (100) includes a fixed latch arrangement and a contact arrangement. The fixed latch arrangement is carried on the electronic device (100) and the battery (200). The contact arrangement has a flat contact (220) carried on the battery (200) and a spring contact (310) carried on the electronic device (100). Upon mating the flat and spring contacts (220 and 310), the spring contact (310) deflects and urges the battery (200) into engagement with the fixed latch arrangement, thereby, securing attachment of the battery (200) and electrically connecting the battery (200) to the electronic device (100).

Abstract: A building containing two rows of squash courts one each side of a central gallery, there being clerestory windows above the gallery, glass walls on each side of the gallery, and divisional walls extending between the gallery glass walls and the side walls so as to form the rows of squash courts each of which receives light through the clerestory windows and glass walls.
