Abstract: A heated, moist air sandwich bin for maintaining sandwiches therewithin sufficiently moist and at pre-selected appropriately elevated temperatures comprising a front always open service opening through which sandwiches may be inserted into and/or removed from the bin. A bin floor divides the bin into an upper sandwich compartment and a lower compartment and defines with the side walls of the bin air flow passages for permitting air movement between the upper and lower compartments. Blower means in the lower compartment forces moisturized air over heaters and through a discharge nozzle extending substantially across the width of and below the service opening. Air directing vanes positioned at the service opening and extending into the upper compartment direct the flow of air discharging the nozzle away from the service opening to create and maintain a dome of hot, moist air over the sandwiches while creating turbulent zones outside the dome to minimize hot, moist air escape through the service openings.

Abstract: A series of like-shelved, convertible refrigerating and heating cabinets, accessible from either one of two sides thereof through self-closing glass doors for self-service and replenishment of prepared food and drinks, and following a door opening of any duration over periods of intermittent replenishing, dispensing and storage conditions, providing fast automatic rapid air condition recovery for uniformity of refrigeration, or heating, and/or humidification of miscellaneous food products accessibly displayed.

Abstract: An easily and readily cleaned, preferably multi-tiered, freely movable, counter-top food display stand for self service which is simple in construction, easy to assemble and maintain and provides full viewability, maximizes accessibility and shields for sanitation the food displayed. The stand is preferably supported at each tier, in whole or a major part, by one leg at each end with the leg of the lowest tier disposed at the front where customer contact might occur and damage be resisted.
