Patent number: 8404292Abstract: A food warming apparatus includes a heating compartment that can hold one or more trays containing previously cooked food portions. A cover for a tray has a horizontal section and a vertical section extending downwardly from one side of the horizontal section. A rack in the heating compartment includes a channel and a stop that blocks the front end of the channel. The vertical section of the cover fits securely in the channel behind the stop such that the rack supports the cover substantially only through the vertical section. When a tray is inserted into the receiving space cooperatively defined by the cover and rack, the cover is lifted up so that the horizontal section rests on the tray and at least partially blocks the open top of the tray, thereby restricting evaporation of liquids from the previously cooked food portions contained in the tray.Type: GrantFiled: December 14, 2011Date of Patent: March 26, 2013Assignee: Prince Castle, Inc.Inventors: Loren J.

Patent number: 8402884Abstract: In a toaster, a toasting carriage is latched during toasting by an electromagnet actuated by a timer control circuit, and released when toasting time has elapsed. One of two rectifying circuits is always live and supplies a DC current to the timer control circuit and another, separate rectifying circuit supplies a DC current to energise the electromagnet when the toasting cycle is initiated. A first switching module switches a current flow through the heating element, while a second switching module isolates the always live rectifying circuit from the heating element. Switches of the first and second switching modules are disposed in an array and are closed by movement of the toasting carriage to the toasting position. More responsive and stable electromagnetic latching contributes to reducing risks associated with a fire that could occur during use of the toaster.Type: GrantFiled: October 22, 2010Date of Patent: March 26, 2013Assignee: Hon Way Plastic & Metal Mfg. Co. Ltd.Inventor: Hon Man Choi

Patent number: 8256343Abstract: A pad holder of a coffee maker for making coffee with a foam layer on top includes a stud plate having studs for supporting a coffee pad containing ground coffee beans and an outlet opening for delivering coffee extract. Studs in the direct vicinity of the outlet opening are arranged in a circle, where surfaces of the studs form a circular directing surface. During operation of the coffee maker, a flow of coffee extract enters a space encompassed by the studs via channels between the studs, and is put into rotation as a result of interaction with the directing surface. Consequently, the coffee flow enters the outlet opening in a rotating condition, causing the outlet opening to deliver the coffee as a spray of fine droplets, from which the foam is created.Type: GrantFiled: April 12, 2006Date of Patent: September 4, 2012Assignee: Koninklijke Philips Electronics N.V.Inventor: Joeke Noordhuis
