Abstract: A module capable of being grouped into multiples to define various articles of furniture, such as bookcases and file cabinets. The module is constituted by top, bottom and side panels whose edges have longitudinal bores therein and are cut to form complementary tongues and grooves creating corner joints, whereby the panels may be compactly packaged and shipped in the flat state and thereafter assembled on a site to create a box-like module having rectangular front and rear openings. The joints are held together and the structure stabilized by a removable strut connector constituted by a pair of intersecting arms each acting as a bridge between a set of diagonally-opposed corners at the rear opening to form a truss, the arms being pivotally interconnected and being provided at their ends with laterally-extending pins that are insertable into the corner bores so that one may collapse the module simply by removing the strut connector.

Abstract: A water mattress having a portion of its volume occupied by air or gas filled bodies lowers the total mattress weight without sacrificing its desirable characteristics. The gas filled bodies comprise independent, elongate, parallel chambers having sidewall members which are secured to the bottom panel of the mattress. The chambers are positioned at approximately the horizontal midplane of the mattress such that it exhibits the conventional uniform weight distribution characteristics found desirable in such devices. Air is supplied to or released from the chambers through access fittings on the chambers and water mattress. The water filled mattress weighs substantially less than a conventional mattress having the same external volume. Furthermore, the chambers tend to inhibit the sloshing and highly under-damped natural harmonic motion typical of conventional water mattresses.

Abstract: A wall panel consisting of two laminar units each including a core layer of particulate, sintered, aluminum oxide, a perforated metal shell enveloping the layer, and a continuous mass consisting essentially of elastomeric material enveloping the shell and extending into the layer through the perforations of the shell. The mass bonds the particles in the layer to each other and to the shell, and the two masses constitute a unitary body connecting the shells in a position in which the core layer of one unit projects beyond the core layer of the other unit so as to define a rabbet. Two such panels may engage each other in a rabbet joint in which the projecting core layer parts are spacedly superimposed on each other to provide a burglar resistant connection between the panels which themselves are difficult to penetrate by burglar's tools.
