The enclosure preferably has transparent side walls, a closure member and a rack comprising a plurality of vertically spaced-apart pan supports each comprised of a plurality of interconnected tubular fluid carrying members, each support is maintained in spaced-apart relationship by fluid carrying conduits which communicate with the tubular members to thereby transfer heated or cooled fluid between supports from a fluid supply inlet to a fluid discharge outlet.

Abstract: A method and apparatus for cooling foodstuff to a temperature of less than 40.degree. F. within the legally mandated time of 4 hours which consists of a refrigeration apparatus capable of forming a bank of ice and means for circulating water over the ice and through an enclosure in heat conductive relationship with a container holding the foodstuff to be cooled.

Abstract: An apparatus and method for disposing of the condensate collected in the drip pan of the evaporator coil of a refrigeration system located within a storage enclosure. An air pump is used to withdraw the condensate by aspiration from the drip pan and deposit it in a storage container outside of the enclosure. The stored condensate is subsequently transferred to a pan open to the atmosphere from which the condensate evaporates.

Abstract: A safety construction for a passenger vehicle having a fixed body portion secured to a chassis and a separable body portion comprising a passenger compartment with a platform secured to the chassis by a resilient release system. The release system includes a plurality of spring means and frangible fastener means adapted to keep the platform in engagement with the chassis until caused to separate upon application of a predetermined shear force.

Abstract: An apparatus for heating food articles including a chamber containing a plurality of vertically, spaced-apart supports, each having a hollow interior which is interconnected by a single conduit. A thermostatically controlled steam generator is connected to the single conduit serving to both transmit steam to the supports and return condensate water back to the steam generator to thereby heat the food articles.

Abstract: An apparatus is disclosed for heating or cooling food articles including a chamber containing a plurality of tubular, vertically, spaced-apart support means having a fluid inlet and outlet. A plurality of removably mounted hollow plates each having a plurality of spaced-apart tubular members having a fluid sealed therein connected to first and second plenums are positioned on the support means. Supply and return header means are connected to the inlet and outlet, respectively, of the support means and by conduit to a fluid reservoir and pump to circulate a fluid transfer means through each support means. Means for heating and cooling the fluid is also provided and control means for controlling operation of the heating and cooling means individually or in a predetermined sequence and at a preselected temperature is also included. During the heating mode the fluid inside the removable plates vaporizes and condenses.

Abstract: A fluorescent-type lamp fixture is disclosed which can be rapidly assembled and has channel and cover members each with means to enable the members to be snapped together. The cover member carries spaced-apart holders for receiving the lamp and other electrical components. A pair of caps are provided which are plugged into the open ends of the assembled channel and cover members, the caps are shaped to insure proper alignment and effect their retention. A lens is also provided having projections that are snapped into recesses in the end caps to hold it securely. In another embodiment, a light shield is rotatably mounted on adaptors positioned adjacent to the caps to direct light to a number of positions.

Abstract: A radial flow cooling tower is disclosed employing a novel circular support structure for housing both a plurality of sections of fill media and sections of a means for entraining fluid droplets and which permit their easy removal for cleaning or replacement. A system is provided for delivering the fluid to be cooled over the fill media and a motor driven fan for drawing air through the fill media as well as through the droplet entraining sections is positioned in an open central area defined by the fluid entraining sections.
