  • Patent number: 6037572
    Abstract: Disclosed are heating and warming assemblies including an electrically resistive thin film. The assemblies generally include a planar substrate, a resistive film for heat generation, one or more electrically conductive electrodes in electrical association with the resistive film, and a non-stick layer disposed on the exposed surfaces of the assembly. The heating and warming assemblies according to the present invention are particularly well suited for use in heating devices and appliances such as ranges and griddles. The assemblies are also incorporated into heating panels for ovens.

  • Patent number: 6034445
    Abstract: Electrical loads are powered by one of several different power sources through a selector switch. A monitoring circuit monitors the different power sources to sense a change of state, that is, power up or shut down. Such a change indicates that the selector switch is likely to be operated to select a new power source. The monitoring circuit shuts down certain loads to limit current surges when the new power source is connected.

  • Patent number: 6006810
    Abstract: An awning assembly for mounting to a curved wall. The awning assembly includes a canopy secured to a roller assembly. The roller assembly is supported by a pair of extensible support arms and a pair of extensible rafters. Each of the support arms includes upper and lower arms locked together by a locking assembly. Inner ends of the rafter are pivotably connected to upper brackets adapted for mounting to the wall. Outer ends of the rafters are slidably and pivotably connected to the support arms. The support arms and the rafters are curved so as to conform to the wall when the awning assembly is in a stored position.

  • Patent number: 6000501
    Abstract: A method and apparatus for adding torsion to a roller tube assembly of a retractable awning which includes a roller tube rotatable about a rod and a torsion spring between the roller tube and the rod. The model number of the roller tube assembly and the required number of turns to obtain the desired torsion is input, by bar code scanner, into a programmable controller. The controller is preprogrammed with data relating to the proper holding assemblies required for various model numbers and boundaries for the data input by the bar code scanner. The controller first verifies that the proper holding fixture is present. The rod is coupled to a drive motor for rotation therewith and the roller tube is secured in the holding assembly to substantially prevent rotation thereof. The rod is coupled and the roller tube is secured solely by longitudinally moving the roller tube assembly into the holding fixture.

  • Patent number: 5974818
    Abstract: A low temperature frozen food display case that allows a consumer to directly view a frozen product contained therein and which minimizes moisture loss from the frozen food. The display case provides an base member which defines a first portion of a cooling air passageway, side walls extending upwardly from the base member, inner and outer members which are sealed to the side walls and the base member and cooperate to define a second portion of the cooling air passageway. A rear wall defines a plurality of access openings which are selectively closed by pivotal doors. Each of the doors define a third portion of the cooling air passageway through which cooling air from an outlet of the passageway first portion is communicated to the passageway second portion. Food contained within the food storage compartment is not directly contacted by cold air which flows through the cooling air passageway surrounding the storage compartment and, therefore, moisture loss is reduced.

  • Patent number: 5973298
    Abstract: A range cook top is provided with circular heating zones having a layer of resistive thin film thereon. Slots in the cook top separate the heating zones from the surrounding areas of the cook top. Tongues of cook top material interrupt the slots and support the heating zones. The slots have beveled or stepped edges and beveled or stepped plastic inserts fill the slots to provide a smooth cook top. Sealer also fills the slots. The resistive layer in the heating zone is divided into arcuate segments by insulating partitions. Power supply bus bars are disposed around the outside edge of the resistive layer. A common bus bar interconnects the segments at the inner edges. A dual heater has separately controlled inner and outer resistive layers.

  • Patent number: 5966965
    Abstract: A ventilation system for an absorption refrigerator having a condenser and an absorber and located in a recreational vehicle. The ventilation system includes a generally vertical air passage in which the condenser and the absorber are located, a lower vent for the intake of ambient air into the air passage, an upper vent for exhausting heated air from the air passage, and an air assist system for forcing air flow through the air passage only when the temperature of the ambient air is too high for an efficient natural draft. The air assist system includes a blower positioned to promote airflow within the air passage over the condenser and the absorber, a temperature activated thermal switch positioned to sense ambient temperature and adapted to energize the blower only when the ambient temperature is above a predetermined value, and a power switch connected in series to the thermal switch to activate and deactivate the system.

  • Patent number: 5944085
    Abstract: A retractable awning is provided with a multiple position pivot support adapted for mounting the awning in different installations. A flange of a mounting bracket fits in one of several slots in the support according to a wall and awning rail structure. A roller is provided with a notch into which is wedged a rope in a hem pocket of the awning. The notch retains the rope and holds the awning taut. Rafter arms a pivotably attached to slides held in slideways on external faces of support arms. A stop and latch mechanism hold the rafter in an extended position so that pivoting of the support arms does not change tension of the awning. An improved roller lock uses a pair of pawls engaging a gear. A spring biases the lock to either of two engaged positions.

  • Patent number: 5940579
    Abstract: A heating panel has a resistive heating layer formed on a substrate. Insulating layers can be formed on the substrate. The heating layer has electrodes on opposite edges connected to different phases of a multiphase power source. Capacitive currents caused in the substrate by the different phases cancel each other. Thus, leakage current is minimized through a conductor connected between the substrate and ground. The heating panel can be adapted for two phase or three phase systems. The heating panels are particularly useful for defining a heating cavity of an oven or pots on a cook top.

  • Patent number: 5933912
    Abstract: An upright wet extractor includes a base assembly, a manipulative handle pivotally attached to the base assembly, and a motor driven agitator brush. A cleaning solution dispensing tank is removably attached to the handle assembly by a pivotable latch member. In a floor cleaning mode, cleaning solution is selectively supplied by gravity from the dispensing tank to a floor cleaning spray nozzle through a supply tube which is controlled by a pinch valve. In an attachment hose cleaning mode, cleaning solution is selectively supplied by a motor driven pump from the dispensing tank to an attachment hose spray nozzle which is controlled by a trigger valve. A suction motor/fan assembly is carried by the base assembly which is selectively in fluid communication with a floor suction nozzle in the floor cleaning mode and an attachment hose suction nozzle when in the attachment hose cleaning mode.

  • Patent number: 5932128
    Abstract: A heating panel has a substrate with a resistive heating material disposed thereon. The substrate can be metal with an insulating layer disposed between the substrate and the heating layer. Alternatively, the substrate can be glass ceramic. The heating layer has electrodes on opposite edges connected to different phases of a multiphase power source. Another electrode on the heating layer can be connected to a neutral of the power source. Capacitive currents caused in the substrate or a metal object on the substrate by the different phases cancel each other. Thus, leakage current through a conductor connected between the substrate and ground is minimized. The heating panel can be adapted for two phase or three phase systems. Power to the panels is controlled by solid state switches or relays. Zero crossing drivers sense supply voltages and operate the switches to balance currents in the panels.
