Abstract: A food service transport cart includes a mobile housing having at least one door containing ports for at least one food service tray therein. A UV light source is mounted in the housing and connected to a source of power. A switch and timer are provided for controlling the source of power to activate the light source for a predetermined period of time after the door is closed.

Abstract: The conveyor system includes a conveyor bed mounted on a frame and an endless conveyor belt moving between upper and lower flight pads relative to the conveyor bed. A separate drive unit for the belts includes an enclosed housing having an opening therein through which the conveyor bed passes. The housing contains a belt drive mechanism including a plurality of belt pulleys engaged with the belt for receiving the conveyor belt from one of the upper and lower flight pads, applying motor power to the belt, and returning it to the other of the flight pads. The enclosure also includes a UV irradiation light source interposed in the path of travel of the belt through the housing for disinfecting the surfaces of the belt and the interior of the housing as the belt passes therethrough.

Abstract: An apparatus is provided for filtering pollutants from exhaust air. The apparatus includes a baffle filter, at least one inlet flow plate, and at least one outlet flow plate. The baffle filter has an inlet-side and an outlet-side, and includes a plurality of baffle channels. The at least one inlet flow plate attaches to the inlet-side of the baffle filter and covers a portion of the plurality of baffle channels. The at least one outlet flow plate attaches to the outlet-side of the baffle filter and covers another portion of the plurality of baffle channels.

Abstract: An exhaust hood is provided for filtering pollutants from exhaust air. The exhaust hood includes a light assembly and an air blower assembly for generating a stream of air in front of the light assembly.

Abstract: A portable wheeled cart for work in yard and garden includes a body having a bottom wall and a pair of opposing sidewalls extending upwardly from the bottom wall. The sidewalls include a plurality of open-ended passageways defined therein for receiving handles of yard tools. In the wheelbarrow position, the yard tools and supplies can be readily transported from one location to another without requiring repeated trips between locations. Moreover, for storing yard and garden supplies and tools, the cart can be rotated into an upright position about the wheel means, wherein the yard tools can be stored and wherein the front and rear walls of the wheelbarrow form shelves for holding lawn and garden supplies.

Abstract: A sanitary conveyor system is disclosed in which a conveyor bed, with or without curves, is mounted on a frame for movement of food trays between a plurality of work stations or movement of soiled trays from the cafeteria to the ware-washing area. A central box channel is mounted remote from the work stations and is provided juxtaposed to and below the pair of conveyor beds. The conveyor system includes a first set of pulleys being disposed adjacent to the tail end of the conveyor beds which are horizontally aligned and angled upwardly from the box channel to the conveyor beds such that each belt in the lower return flight path of the box channel are moved upwardly to the corresponding upper flight path of the conveyor bed. A second set of pulleys is disposed adjacent to the drive end of the conveyor bed and operatively connected to a belt drive unit such that belts are moved from the upper flight path of the conveyor bed to the lower return flight path of the box channel.

Abstract: A heat storage dish for use with food serving ware such as a plate or the like has upper and lower dish walls of generally complementary peripheral configuration, with the walls being secured together at their peripheries and the remainder of the walls being spaced from each other to define a cavity therebetween. A heat storage plate is positioned in the cavity between the walls, and the plate has at least one opening formed therein. The plate is held in close heat transfer relation to the upper wall by a flange support member which is secured to the upper wall and extends through the openings to a pair of outwardly extending flanges on which the plate is supported. A layer of heat insulating material extends entirely across the bottom of the plate, between the bottom of the plate and the bottom wall, to prevent heat losses from the plate through the bottom wall of the dish.
