  • Patent number: 4813726
    Abstract: The invention relates to panels, such as are provided in cabinets or the like. Rabbets are provided in a frame for receiving a panel. Mortises are provided extending in the frame from the rabbets, and rotatable retaining element are mounted in the mortises. The rotatable retainers are comprised of a ramp encircling them for a proton of their circumference, having one flat circumferential side that is alignable with the side of the rabbet in the frame. Accordingly, upon rotation of the retainer, the ramp, or screw thread, engages the side of the panel away from the bottom of the rabbet, to hold the panel fully against the bottom of the rabbet, independently of the thickness of the panel.

  • Patent number: 4761539
    Abstract: In an oven calibration system, a value is stored corresponding to a predetermined temperature, and a calibration value is also stored corresponding to an offset. The calibration value is variable. A temperature sensor produces an output that is compared with a predetermined combination of the stored values. The calibration value may include a fixed increment and a variable multiplier for combination with the fixed increment.

  • Patent number: 4754948
    Abstract: Electric and gas ranges are provided with either projections or openings which, together with corresponding openings and projections on the adjacent wall behind the ranges, cooperate in order to prevent the tipping of the range when the oven door is open and assuming a generally horizontal position, whereby weight is applied to the door of sufficient magnitude to cause the range to tip over unless the corresponding projections and openings are interfitted.

  • Patent number: 4613192
    Abstract: A strain relief for a power cord for electric devices includes a molded insulating body into which the power cord extends, a grounding lug extending from another side of the body and connected to the ground lead of the power cord. Grooves are provided in the sides of the body to enable the body to be assembled in a slot of the electric device, with the grounding lug of the strain relief adjacent a wall of the electric device, so that the grounding lug may be held to the wall of the device by a screw. The grounding lug may be used to function as a strain relief or auxiliary metal may be provided as a retainer. Connectors extending from the device on the portion opposite the grounding lug are adapted to be connected to leads within the electric device, the connectors being, for example, spade lugs. A fault sensing device such as an automotive fuse may be coupled to additional connectors on the body.

  • Patent number: 4568810
    Abstract: A microwave oven with a microprocessor control which contains stored recipe information. The user enters food type, quantity to be cooked, and size or doneness desired. Data for cooking a large number of different foods may be stored. The specific food item to be cooked is user selected by touching and holding one of ten food category pads. Food items within the category selected then "scroll" through an alphanumeric display. The item shown in the display when the food pad is released is the one selected for cooking. Following food selection, the user is prompted, via the alphanumeric display, to enter such additional data as quantity, size and doneness desired.

  • Patent number: 4375587
    Abstract: A fan motor sequencing switch assembly is employed to effect delayed full power energization of a magnetron in a microwave oven for protecting the magnetron and energization circuit therefor against high start-up current surge and for cooling the magnetron during oven operation. The sequencing switch is connected in parallel with a start circuit consisting of a start switch and serially connected current limiting resistor, and is operated by an actuator movable by the magnetic field induced in the fan motor upon energization, the motor being connected to the start switch and sequencing switch for energization through either switch.

  • Patent number: 4321447
    Abstract: An energization circuit for a microwave oven employs a PTC thermistor to eliminate high transient current surges resulting from energization and deenergization of induction elements therein to provide circuit protection both during oven start and operation. The energization circuit comprises first and second parallel circuit portions for energizing a transformer used to energize a magnetron that produces microwave energy, the first circuit portion including a normally open start switch and a current limiting PTC thermistor coupled in series relation and the second circuit portion including a relay operated switch, a relay for operating the relay operated switch, and a relay circuit portion connected to the first circuit portion between the start switch and PTC thermistor for energizing the relay upon closure of the start switch and then through the PTC thermistor upon opening of the start switch.

  • Patent number: 4310933
    Abstract: A disposer mount assembly includes a non-rotatable plastic sink flange having a tubular portion extending downwardly through and beneath the drain opening and terminating in a lip resiliently embraced by an elastomeric cushion mount, a mounting ring with inclined camming slots rotatably mounted on the tubular portion by the cushion mount, and a disposer hopper having an upper flange with lugs projecting radially outwardly therefrom into the camming slots. Selective rotation of the mounting ring cams the lugs upwardly along the inclined camming slots to a final locked position therein in which the correspondingly elevated hopper flange is connected to the mount ring and compresses the cushion mount, thereby to provide a tight resilient seal between the disposer and sink flange to absorb vibration and sound.

  • Patent number: 4108139
    Abstract: The gas burner and blower powered oven includes a mixing chamber of appreciable length that receives bottom outflow air from the oven and, in general opposition, an input from the burner which includes make-up room air. A substantial flame is produced in the chamber for combusting volatiles in the oven outflow and the latter is mixed in the chamber before proceeding to the inlet of the blower, the latter discharging the hot air into the oven through a multiplicity of holes in a top manifold for downward substantially uniform flow throughout the oven.

  • Patent number: RE29853
    Abstract: A solid-state silicon carbide gas igniter to which electrical leads are bonded for energization by flame or plasma spraying as used for hardfacing alloys, metals and ceramics, the leads being received in slots in the igniter terminal parts and the latter, with the thus inserted leads, encased or coated by the spray bonding material. In applying such material, the centerline of the spray is directed at an angle of approximately 45.degree. toward the terminal end of the igniter while the latter is preferably relatively rotated to provide the material coating fully about the terminal parts of the igniter and the inserted leads.
