Abstract: A portable sink having a sink module and a hot and cold water outlet connected to a spigot and a used water outlet from said sink connected to a cabinet mounted on wheels having at least one door to access the interior thereof. At least one tank for fresh water and a reservoir for used water is mounted in the cabinet. An electrical connection for powering a pump and a heater connected to the outlet of the pump has an outlet connected to the hot water outlet and a connection from the pump to the cold water outlet. A hammer arrester diminishes line surges and fluidic pounding from the pump, and a flow check valve prevents back flow to the fresh water tank.
Abstract: A portable bar having a sink disposed therein having a base member having a central opening with a trough disposed peripherally around the opening. A cold plate is sealed against a side wall of the trough within the sink opening. The cold plate is formed of a heat transfer material such as a metal formed into at least one major surface and has a plurality of internal channels for circulation of fluid to be cooled. A peripheral flange surrounding the cold plate has a unique inwardly angled leading edge and an outwardly angled trailing edge for sealing to the trough of the sink.

Abstract: A food bar is formed of a double walled, insulated open chamber and a support grid disposed within the chamber. The support grid is formed of divider bars and cross rails arranged in a pattern across the open chamber of the food bar to divide the opening into compartments for support of food containers and panel inserts. The divider bars have a substantially U-shaped cross section and have spaced apart openings along the top. The cross rails have a substantially U-shaped cross section and have ends which terminate in a downward flange adapted to be received in the openings of the divider bar. A clear panel of material is preferably suspended above the food bar to act as a "sneeze bar".
Abstract: A movable cart comprising a base member having a generally rectangular shape supported on a plurality of swivel casters and having two sidewalls joined to a rear wall, and including channels disposed within the base member and/or the walls for accommodating one or more panels for dividing the cart into two or more compartments. The panels have a double flanged edge sized to fit into the channels of the base member and a single flange sized to fit into the channels of the walls. The panels are secured to the walls by means of a screw member which passes through the walls and is received into an internally threaded opening in the edge of the panels.
