Patent number: 7310969Abstract: A method and apparatus for controlling the environment of cargo through lateral ventilation. The method provides for a controlled fluid to be supplied into a cargo compartment having a lateral portion, the fluid being supplied through a vent in a supply-conduit adjacent the lateral portion. In practice, this result can be achieved by building a structure that encloses a cargo compartment having a lateral portion, running a supply-conduit adjacent the lateral portion, connecting the supply-conduit to receive a controlled fluid from outside the cargo compartment, and conducting the fluid into the cargo compartment through a vent in the supply-conduit. On mixing with the environment within the cargo compartment, the fluid will influence components of the environment, for example the humidity and the temperature.Type: GrantFiled: July 29, 2005Date of Patent: December 25, 2007Assignee: Coldwall, Inc.Inventor: Robert Dale

Patent number: 7297904Abstract: A convection oven includes a heat exchanger section and a product receiving section, the product receiving section including a door to provide access thereto. An air flow system includes at least one blower and an air flow path for enabling air to circulate from the heat exchanger section where it is heated, into the product receiving section for transferring heat to food products, and back to the heat exchanger section for further heating. The air flow path includes a passage providing flow communication between the heat exchanger section to the product receiving section, where the passage is located proximate to a wall and configured such that heated air from the heat exchanger section is directed along an internally facing surface of the wall so as to attach to and flow along the internally facing surface of the wall from one side of the product receiving section toward an opposite side of the product receiving section.Type: GrantFiled: September 18, 2003Date of Patent: November 20, 2007Assignee: Premark FEG LLCInventor: Hans Paller

Patent number: 7102105Abstract: An electric oven including lower heaters arranged under a cooking chamber thereof. The electric oven includes an outer case defining the appearance of the electric oven, an inner case inwardly spaced apart from the outer case by a predetermined distance, and lower heaters arranged between bottom walls of the outer and inner cases. The inner case internally defines a cooking chamber, and a blowing fan is installed near the lower heaters to circulate air existing in the cooking chamber toward the lower heaters. With the electric oven configured as stated above, heat generated by the lower heaters is transferred to the cooking chamber in the form of conductive heat and convective heat, resulting in fast and efficient heat transfer and even cooking of food.Type: GrantFiled: July 7, 2005Date of Patent: September 5, 2006Assignee: Samsung Electronics Co., Ltd.Inventor: Keun Seuk Oh
