Abstract: A housing for batteries which may be combined with a battery charger in a mechanically integrated module. The module is mobile and includes a load-bearing frame, battery retaining members, and mechanical stabilizers. The base of the frame includes a raceway or channel for routing interconnecting wires between the charger assembly and batteries. The battery retaining members permit easy installation or removal of individual batteries from the housing as well as inhibiting lateral movement of the batteries within the housing. When the module is free-standing, the stabilizers deploy automatically for enhanced mechanical stability.

Abstract: In a video display terminal having a housing and a cathode ray tube mounted in the housing, there is provided shift restricting means for applying a selected level of force between mounting ears of the tube and the housing in a direction generally perpendicular to the central axis of the tube. In a preferred embodiment, angle brackets are mounted inside the housing between the enlarged end portion of the cathode ray tube and inside corners of the housing, and lateral force is applied between the angle brackets and the enlarged end portion of the tube for rigidifying the housing. The lateral force is applied by wedges mounted in the brackets for sliding against the mounting ears, and screws are coupled to the brackets for forcing the wedges against the mounting ears.

Abstract: A chassis and circuit modules for controlling electromagnetic interference in high-speed digital transceiver circuits. The impedance between a reference ground point and the transceiver circuits and a chassis wall through which the transceiver circuit signals pass is kept very low by intimate physical contact between a conductive bulkhead section of the module and the ground plane used by the transceiver. In particular, there is disclosed an arrangement whereby a plurality of modules are placed adjacent one another in a cabinet. Each of the modules contains a conductive bulkhead section or handle, which engages other adjacent bulkhead sections, and which may have an input/output connector mounted thereon. Each module also has a printed circuit board mounted to the bulkhead section so that a forward-circuit reference path reserved for use by transceiver circuits is positioned adjacent the connector and electrically connected to both the connector and the front section via a low impedance path.
