Abstract: An oven for heating food and associated components and methods. The oven includes a food heating compartment bounding a food holding space for holding food to be heated. The food holding space has an open top. A bottom wall of the food heating compartment supports food in the food holding space and has gas flow inlets. A gas supply plenum is disposed below the food holding space and is in fluid communication with the food holding space via the gas flow inlets. A gas supply duct defines a gas supply passageway disposed below and fluidly coupled to the gas supply plenum. A heater heats the gas as the gas flows through the gas supply passageway. A blower blows the gas through the gas supply passageway, into the gas supply plenum and through the gas flow inlets into the food holding space for heating the food.

Abstract: A system and method for providing a voice communication service between a first user and a second user after the first user and the second user are communicating via a non-voice communication service is described. The non-voice communication service may be processed through a server in communication with the first and second users. The non-voice communication service is monitored for a voice service request, and upon receipt of the voice service request, establishment of a voice communication service is initiated between the first and second users through the server. The first and second users may be anonymous to each other over the non-voice communication service and the voice communication service.

Abstract: A solenoid operated valve for supplying a liquid refrigerant has an inlet port, or outlet port and a valve port therebetween, the outlet port having a restricted opening equal to or smaller than the opening of the valve port, a capillary tube in the outlet port, and a passageway between the valve port and the outlet port having a small volume capable of substantially preventing expansion of liquid refrigerant.
