Patent number: 5505009Abstract: The present invention relates to a food storage, display, and warming apparatus having a first storage compartment for holding bulk food at a predetermined temperature above ambient temperature and including one or more door members for accessing the bulk food therein, a second storage and display compartment for holding and displaying a plurality of individualized food portions and including one or more transparent door members for viewing and accessing the individualized food portions therein, a heater and blower arrangement for circulating heated air between the first and second storage compartments, a thermostat for sensing the temperature in the first storage compartment and for discontinuing operation of the heater when a maximum temperature is sensed to avoid overheating the bulk food.Type: GrantFiled: October 24, 1994Date of Patent: April 9, 1996Assignee: Six Corners Development CompanyInventors: Andrew M. Stein, Andrew Jinks

Patent number: 5388348Abstract: A drying machine has a predrying operation. In the predrying operation before heated air is supplied to the drying chamber to dry clothes in the drying chamber, the drum repeats the rotation of the clockwise and counterclockwise alternately in a short cycle, so that entwined clothes are got loose. During the predrying operation, cool air is supplied to the drying chamber. Then the heated air is supplied to the drying chamber, so that clothes are dried.Type: GrantFiled: March 9, 1993Date of Patent: February 14, 1995Assignee: Kabushiki Kaisha ToshibaInventors: Miho Tanaka, Kinya Hayashi

Patent number: 5315765Abstract: A fabric drying system has an exterior housing and a rotating chamber for containing fabric laden with moisture that is to be dried and uses a combination of microwave energy and an auxiliary convection air heater to heat and vaporize the moisture and expel it with exhaust air so as to dry the fabric. In addition, the fabric drying system employs energy efficiency devices that permit the system to dry the fabric using the least amount of energy. Heat energy from the exhaust air is transferred to the intake in a heat exchanger. Additionally, heat energy from the exhaust air is used by recirculating a portion of the exhaust air and mixing it with the intake air before the air is introduced into the fabric drying chamber. The system also provides for sensors that detect the temperature and/or humidity of the exhaust and the intake air.Type: GrantFiled: April 27, 1992Date of Patent: May 31, 1994Assignee: Melvin HolstInventors: Melvin Holst, Paul S.
