Abstract: A cable car type vehicle arrester features a pair of trumpet bars which are interconnected by a link which either maintains the distance between the bars constant or reduces same upon one of the bars being deflected outboard of its home or rest position. This reduces the free swinging time of the vehicle between bars and increases the distance through which the bars subsequent to the initial deflection are deflectable by the vehicle. This accordingly increases the stroke of shock absorbers associated with the bars increasing the conversion of the kinetic energy of the vehicle. Casters can be provided to support the bars to allow longer lighter bars with less robust bearing and structural members. The casters can be run on a corrugated surface to cam the bars vertically further increasing the kinetic energy conversion and endow a self-centering action on the arrester.

Abstract: An optical recording element which comprises a heat-resistant organic resin substrate; a recording layer formed on said substrate by thermal deposition or sputtering; and a transparent organic resin protective layer mounted on the recording layer, and wherein the organic resin substrate and organic resin protective layer are thermally fixed under pressure with the recording layer laid between them.
