Patent number: 8362404Abstract: A container configured to establish an air flow curtain at an open end thereof is provided. The container includes a housing defining an internal volume with opposed five mutually perpendicular walls and an open end allowing access to the internal volume. A heater and a fan are disposed within the housing. An assembly is removably positioned within the internal volume of the housing and configured to be removed from the internal volume in a single motion without any external tools, the assembly comprises five mutually perpendicular walls and an open end allowing access to an internal volume within the assembly. When the assembly is positioned within the housing, a first plenum is defined within a space between the rear wall of the assembly and the rear wall of the housing, and a second plenum in fluid communication with the first plenum is defined within a space between the lower wall of the assembly and the rear wall of the housing.Type: GrantFiled: May 17, 2010Date of Patent: January 29, 2013Assignee: Carter Hoffmann, Inc.Inventors: Paul M. Emerich, Gregory T. Landeweer

Patent number: 8357886Abstract: A drawer type cooking device for disconnecting and connecting the linkage between the drawer body and the movement mechanism in response to the user's selection of operation between a manual opening/closing operation and an electric automatic opening/closing operation of the drawer body. Based on the user's input via the operation unit, connection/disconnection of power transmission via a clutch mechanism and driving/stopping of a drive mechanism is automatically controlled. By turning the clutch mechanism off and isolating the drawer body from the motor, the load of manual operation to open/close the drawer body is reduced. Based on the user's operation via the operation unit, the clutch mechanism is set to connected state, and in that state, the drive mechanism is driven so that power is transmitted to the rack of the drawer body, and the drawer body can be automatically opened and closed.Type: GrantFiled: May 15, 2009Date of Patent: January 22, 2013Assignee: Sharp Kabushiki KaishaInventor: Akihiro Yoshidome

Patent number: 8353242Abstract: A fryer has an oil container, a rotatable cooking basket therein, and a body of oil in the container. The body of oil and a stream of air are heated, and the basket is positioned with the food therein at least partially above the body of oil so the heated air stream can circulate through the basket and air-cook the food. Cyclically the basket is at least partially immersed in the heated oil to also cook the food with the oil.Type: GrantFiled: May 18, 2009Date of Patent: January 15, 2013Assignee: De'Longhi S.p.A.Inventor: Giuseppe De'Longhi

Patent number: 8350191Abstract: Embodiments of apparatus for thermally conditioning probe cards prior to use in a testing system are provided herein. In some embodiments, a probe card thermal conditioning system may include an enclosure configured to support a probe card and a heat transfer element disposed proximate a bottom of the enclosure for thermally conditioning the probe card prior to installation in a prober. The heat transfer element may be a heating and/or cooling element. A controller may be provided for controlling operation of the heat transfer element, optionally with temperature feedback. Multiple enclosures may be provided for independently conditioning multiple probe cards. The enclosure may be contained in a cart or may be part of shipping container for shipping a probe card. A fan may be provided for circulating air within the enclosure. The fan may facilitate providing a dry purge gas to prevent condensate from forming on the probe card.Type: GrantFiled: November 10, 2008Date of Patent: January 8, 2013Assignee: FormFactor, Inc.Inventor: Douglas S. Ondricek

Patent number: 8350192Abstract: An oven includes an interior cavity and a convection heating system for developing a flow of heated air within the interior cavity. The convection heating system includes a plurality of fans to provide a plurality of airflows, and a single convection heating element for heating the plurality of airflows. A shroud is arranged in covering relationship over the convection heating system and includes at least one intake aperture, and a plurality of exhaust apertures for discharging air from the plurality of fans back into the interior cavity. A baffle is located within the shroud and generally between adjacent ones of the plurality of fans. The baffle inhibits mixture of the airflows of each of the fans within the shroud. In one example, a first fan provides a first airflow, a second fan providing a second airflow, and the baffle inhibits mixture of the first and second airflows within shroud.Type: GrantFiled: July 18, 2008Date of Patent: January 8, 2013Assignee: Electrolux Home Products, Inc.Inventors: Bryan Thomas Phillips, Cédric Damien Catalogne

Patent number: 8344289Abstract: An electric cooking range includes an oven having an electric baking element and a back panel positioned behind the oven. A spacer bracket is positioned between the back panel and an electrical terminal block. A bottom panel is positioned below the bracket and spaced apart from a number of mounting feet so as to create a gap between the bottom panel and the mounting feet. The bracket has a passageway positioned over an opening formed in the bottom panel such that when the baking element is energized, air from the gap is drawn into the passageway and advanced upwardly along the passageway.Type: GrantFiled: April 21, 2010Date of Patent: January 1, 2013Assignee: Whirlpool CorporationInventors: Paul R. Rogers, David R. Sampson, Gregory S. Wade
