Abstract: A reconfigurable magnetic therapy apparatus is formed by multiple magnetic components which are maintained in a stable planar array by either mutual magnetic attraction or mechanical fixtures which may include a ferromagnetic backing plate to which the elements are magnetically attached. The array can be separated and reconfigured by the user to provide different magnetic patterns that favor either high surface strength, or deep penetration, or multiple smaller sub arrays to treat multiple sites.

Abstract: A magnet apparatus comprising a plurality of geometrically shaped nested magnetic elements each being of a different size relative to each other and each having a first side with a first magnetic pole orientation and a second side with a second magnetic pole orientation that is opposite to the first magnetic pole orientation, capable of being assembled concentrically to form a single planar magnet array having a treatment surface and an opposing backer surface, the treatment surface having either an all like magnetic pole orientation or a mixed magnetic pole orientation; and a backer plate having a first side and a second side constructed of ferromagnetic material such that when the plurality of geometrically shaped nested magnetic elements is assembled concentrically on the first side of the backer plate each of the geometrically shaped nested magnetic elements that comprise the single planar magnet array is secured to the first side of the backer plate by magnetic attraction whereby the treatment surface of

Abstract: A support arm system for selectively positioning relatively heavy objects such as television sets consisting of articulated forward and rear arms each comprised of parallelogram linkages which are each sprung to counterbalance the load weight. A special mounting of the forward arm springs enables a compact configuration, but which introduces slight unbalance conditions in some arm positions. An adjustable friction brake arrangement is incorporated in a pivot point of each linkage which applies a braking force to insure stable positioning of each of the arms in any position throughout the motion of the arm system notwithstanding unbalanced conditions. Also disclosed is a quick connect feature for mounting the supported load to the forward arm, which is combined with a parking lock securing the forward arm in a folded position, which parking lock is released during the connecting feature.

Abstract: An equipoising arm structure which can support relatively heavy objects, yet is compact in shape, and which can be counterbalanced by commercially available springs. The mechanism employs conventional parallelogram linkages for its lower and upper arms, with the lower arm being connected between a base bracket and a floating bracket, and the upper arm being connected between the floating bracket and a support bracket for the object. The upper arm includes a unique springing arrangement in which the ends of the springs attached to the brackets are connected beyond the conventional point of connections so as to maximize the lift of the springs when the upper arm is horizontally disposed. Means are provided for compensating for the non-linearity of such a springing arrangement over the range of angles of the upper arm that would otherwise normally occur.

Abstract: A food holder arrangement is disclosed for use in delivering meals including both hot and cold food items to points of consumption remote from the point of preparation with the hot and cold food temperatures maintained. The food holder arrangement includes a flat tray having a heat retaining insert extending over a portion of the area of the tray. A pair of covers are also provided, one extending over the area occupied by the heat retaining insert, the other extending over a remaining area of the tray, with this other cover having in its top a heat absorbing insert. This location of the respective inserts is such that upon preheating and prechilling of the inserts, convection currents result within the respective covers which are augmented by conductive and radiation heat transfer effects so as to maintain the hot and cold food temperatures.

Abstract: A method and apparatus are disclosed for heating discrete areas of a surface bearing a thermoplastic or heat-activated adhesive or coating for the purpose of producing a thermal sealing of the surface with respect to another contacted surface as in the thermal sealing of flaps of paperboard containers. The method consists of the utilization of a radiant energy source focused onto the seal area to be activated. The radiant energy source is selected to have characteristics enhancing the focusability of its emissions, i.e., approximating a point source and having a relatively high proportion of visible and near visible range wavelength emissions.

Abstract: Meals for institutional feeding are arranged on trays in a central commissary with hot and cold food portions in separate containers. The containers for the hot items have bases formed with metallic plates and thermally insulated covers with internal metallic heat radiators. The trays are arranged in stacks in a refrigerated transport cart having spaced shelves which extend between the trays and include induction heating coils which produce heat generating currents in the metallic elements of the bases and covers of the hot food containers, heating these food portions while the other items are refrigerated. The hot food containers are provided in a variety of configurations each of which is heated at a different rate by the coils so the serving temperature of the food is determined by the type of its container.
