Abstract: A temperature control flow valve has a body defining conduits for connection to sources of cold and hot water, a chamber for mixing the water, and a thermostat element for maintaining the temperature of the mixed water at or below a predetermined maximum temperature. The cold and hot water are combined through a mixing valve in a ratio (adjusted continuously by means of the thermostat element) to provide the mixed water at the predetermined temperature. The flow valve includes cold water and hot water pressure regulators, the hot water regulator being responsive to the pressure of the cold water to maintain the pressure of the hot water delivered through the regulator substantially equal to the pressure of the cold water.

Abstract: A refrigerator display cabinet includes a refrigerated chamber having at least one transparent display window. A condenser and a compressor are positioned below the refrigerated chamber, and a fan draws exterior air through the condenser to thereby warm the air and then directs the warm air to the compressor. A deflector diverts a portion of the flow of warm air from the condenser to the compressor into a duct including a first duct portion extending horizontally from the deflector above the compressor. The dimension of the first duct portion in a direction transverse to the direction of air flow progressively decreases away from the deflector. The first duct portion opens laterally along one entire side thereof. A second duct portion is connected to and extends upwardly from the open side of the first duct and opens in a direction toward the outer surface of the display window.
