Title: Improvements in belt conveyors
IPC: B65G39/04
Filed: 1960-11-21
Abstract: 973,966. Troughing rollers for endless conveyers. GOODMAN MANUFACTURING CO. Nov. 21, 1960 [Nov. 24, 1959], No. 39999/60. Heading B8A. The rollers 41 of a troughing idler assembly are formed from a hard non-metallic wearresistant material such as ceramic, glass or hard plastic and are keyed to rotate with a carrying member 42 by splines. The member 42 is wire or nylon cable 43 encased in a resilient elastomer 44, e.g. rubber or neoprene, and notches 47 prevent the elastomer slipping along a sleeve 45 which is mounted in a roller bearing 37. In assembling the rollers on the carrying member 42, Fig. 6, a plurality of rollers are threaded on an eye-bolt 62 attached to the upper end of the carrying member, the lower end being anchored at 61. The carrying member is then tensioned and the rollers are pushed into position by a tool 64. The diameter of the un-splined hub portions 53 of the carrying member is slightly larger than the crest diameter of projections 58 on the internal periphery of the rollers and are deformed as the rollers slide across the hub portions. To minimize wear on these portions, the rollers may be slid half way along the carrying member from each end. A plurality of the assemblies is secured to flexible strands or cables 18 which are clamped to hangers 39 provided on telescopic supports 13.

Title: Commercial retail package with unfrozen ice cream
IPC: B65D77/20
Filed: 1977-10-06
Abstract: In the package containing unfrozen ice-cream for freezing by the end user, a pot-shaped container (11) of weldable plastic, whose cross-section widens from the container bottom to a container mouth located opposite the bottom, accommodates the unfrozen ice-cream. The container mouth (12) is closed by a lid (16) inserted therein with a circumferential edge flange (17) received in a depression (15) surrounding the mouth of the container. This edge flange is held in its position closing the container mouth in a liquid-tight and germ-tight manner by means of a tear-off covering film (23) which is welded to an edge surrounding the container mouth. The essential factor in this case is that the covering film spread over the lid is welded on the one hand to the circumferential edge of the bottom part of the container and, on the other hand, to the edge flange of the lid extending approximately in the plane of the circumferential edge of the bottom part of the container so that the liquid ice-cream accommodated inside the container is also hermetically sealed off relative to the gap between the covering film and the lid. <IMAGE>
