Abstract: A retractable mounting clip arrangement is provided for use with miniaturized, hand-held apparatus intended to be worn on the person of the user such as on a belt or in the shirt pocket. The clip arrangement includes a curved base plate assembly designed to position with a corresponding curved recess in the apparatus housing. A mounting clip, preferably formed of a thin steel strip is pivotably hinged to the base plate. The base plate is made to slide within the curved recess so that in one position the mounting clip is substantially flush with the surface of the housing and in still another slidable position the mounting clip is positioned entirely above the housing surface and operable to clamp onto a shirt pocket or belt.

Abstract: A detachable mounting clip arrangement is disclosed especially suited for application with miniaturized radio apparatus or the like of the type intended to be worn on the person such as on a belt or in the shirt pocket. The clip arrangement includes a tapered base plate assembly designed to insert within a recess formed by two convergent undercut side walls on the apparatus housing itself and retained therein by a ratchet like serrated section included on the housing surface which interacts with a resilient finger extending laterally from the base plate. The base plate itself is designed to support a conventional pivotable mounting clip assembly and associated torsion spring.

Abstract: A structure for clamping a plurality of battery cells to prevent deformation thereof, includes a pair of pressure plates positioned against the ends of a stack of battery cells and a plurality of bands which extend around the cells and the end plates to hold the end plates in fixed position with respect to each other. The structure can be used with a plurality of sealed cells of rectangular configuration to pevent expansion of the cells of the type where pressure can build up therein, such as ni-clad rechargeable batteries, and thereby prevent bulging of the electrodes of the cells to injure the same. The pressure plates can be made of steel to also serve as heat sinks during welding of the bands, and the bands can be formed of steel strips which are preferably cinched tight about the cells and welded together. Partitions can be positioned between adjacent cells, with edges welded to the bands to prevent expansion of the cellsin a direction parallel to the pressure plates.
