Abstract: Food products are placed on spaced baskets and conveyed into an enclosure, through a irradiation chamber, and then outwardly from the enclosure. The food products are conveyed through tortuously arranged ductwork which serves to absorb radiation streaming upwardly. A portion of the conveyor is positioned within one or more casings and can be withdrawn, if necessary, to facilitate maintenance and repair.

Abstract: An irradiator which can be incorporated within a packing house and a method of irradiating food in the packing house are disclosed. Food products are placed on spaced baskets and conveyed into an enclosure, through a irradiation chamber, and then outwardly from the enclosure. The food products are conveyed through tortuously arranged ductwork which serves to absorb radiation streaming upwardly. The radiation source is maintained underwater both during operation and shutdown, and no lifting of the radiation source is thus required. A portion of the conveyor is positioned within one or more casings and can be withdrawn, if necessary, to facilitate maintenance and repair.

Abstract: The present invention provides a system of irradiating food products in product-containing canisters. The canisters are adapted to retain a plurality of cartons of food product. The canisters are initially positioned on the trailer bed of a truck or similar vehicle and are taken to an unloading station. The canisters are preferably unloaded in pairs from the station and are conducted underground to an irradiator building. The irradiator building includes elevators for lifting the canisters into an irradiation path where the canisters are conducted past a plurality of radiation source plaques. The canisters can then lowered by a second elevator within the irradiator to a position underground, where they are conducted by a third conveyor to a loading station. The irradiated canisters are then loaded onto a truck bed and taken to their ultimate destination.

Abstract: The disclosure is directed to modular irradiators for irradiating bulk and/or palletized materials characterized by each bulk material irradiator including a self-contained conveyor unit including a tube through which bulk material is fed vertically downwardly into an interior chamber, a spiral screw which during rotation thereof conveys the bulk material upwardly through the interior chamber, and gamma ray source elements which emit gamma rays to irradiate the bulk material during its downward and upward movement through the interior chamber. A conveying system is also positioned outwardly of the gamma ray source elements for effecting spiral and reciprocal/rotary movement of palletized and/or packaged material relative to the gamma ray source elements.

Abstract: A unitized floor panel is formed having at least one row comprising a plurality of unattached wooden tiles assembled in generally abutting relation. A layer of pressure sensitive adhesive covers at least a portion of the upper surface of the tiles and is in turn covered by a flexible and removeable support and protective sheet which covers the adhesive and tiles. The adhesive bond formed between the sheet and the adhesive is stronger than the bond formed between the adhesive and the tile so that the sheet and adhesive can be easily stripped from each panel when desired. The wooden tiles can either be finished or unfinished and can be formed from acrylic wood tiles arranged in parquet fashion. The cover sheet is preferably formed from either transparent plastic film or paper having a printed design corresponding to the design and arrangement of the tiles onto which it is positioned. The sheet can include perforations to control cure rate of the sub-flooring adhesive onto which the panels are placed.
