  • Patent number: 7095333
    Abstract: An optical interface using indicator lights is provided for an appliance having a vacuum fluorescent display (VFD) by mounting the indicator lights behind a VFD. In a VFD having a dark background, apertures are formed in the VFD so the indicator lights are enabled for optical communication through the VFD. Preferably, the apertures are formed in the dark layer covering a glass substrate in the VFD so the dark layer helps absorb reflected light that may cause optical noise in the light signals being communicated. Each aperture may be located equidistantly from a group of four pixels in the VFD.

  • Patent number: 6719228
    Abstract: A baffle for a food waste disposer to reduce noise is disclosed. The baffle has a diaphragm that allows solid and liquid waste to pass through the diaphragm, and accordingly does not substantially affect the normal operation of the disposer. However, because the baffle covers the central opening in the conventional mounting gasket of the prior art, a direct path from the grinding mechanism in the disposer to the sink is blocked, thus muffling the noise coming from the grinding mechanism. Additionally, the disclosed baffles are preferably, but not necessarily, designed so as to create a water dam on their surface by impeding the flow of water from the sink faucet in a way to create a pool of water. The disclosed baffles may be installed in the drain opening of a sink above the conventional mounting gasket, although other embodiments are also disclosed.

  • Publication number: 20030164559
    Abstract: Various configurations of discharge valves for humidifier water containers are disclosed herein. Among other things, the present invention provides simple and economical discharge valves that may be constructed in one piece using an elastic material such as silicone rubber. One configuration includes a valve body and stopper with an elastic rib integrally formed with the valve body and the stopper having adequate length to maintain the stopper in a closed position absent external forces. Another configuration uses a flexible barrier is integrally formed with a valve body. The barrier has a slit through its thickness, and is sufficiently resilient to prevent liquid flow through the slit under the weight of water inside the container. In accordance with other aspects of the invention, the valve has a flexible member defining a base and a generally cylindrical sidewall that has at least one opening therethrough.

  • Patent number: 6579077
    Abstract: A deep well submersible pump has a pump housing containing an electric motor. The motor is radially spaced from the pump housing interior surface defining an annular channel through the pump housing from an inlet opening to an outlet opening of the housing. The motor is mounted on a cowling that has an exterior surface. A plurality of deswirler blades extend between the pump housing interior surface and the cowling exterior surface. As the deswirler blades extend through the housing interior, a spacing between the-cowling exterior surface and the housing interior surface expands radially. The cowling exterior surface and the pump housing interior surface define an annular liquid flow path that is first directed radially outward from the inlet opening and then curves around the cowling and is directed axially through the deswirler blades to the annular channel between the motor and the pump housing interior surface.

  • Patent number: 6494653
    Abstract: The present invention is a wall anchor having a novel finger configuration. This wall anchor has a head and barrel portion with a bore extending therethrough and laterally expandable fingers in general alignment with the bore. Instead of a straight channel, a channel having curved portions separates the fingers. The curved portions of the channel define ramp surfaces that at least partially extend into the path of a securing member created by the bore. Thus, when a securing member, such as a bolt, pin, screw, nail or similar object is inserted into the bore to secure the wall anchor to the wall, the securing member contacts the two ramp surfaces, separating the fingers. As the fingers separate, a portion of the fingers near the ramp surfaces deform such that the ramp surfaces rest on an outer portion of the securing member, thus providing a securing force for connecting the wall anchor to the wall and relieving stress on the area at which the fingers are connected to the barrel.

  • Patent number: 6465752
    Abstract: A switching apparatus and electromechanical latching system includes an elastomeric button with independently movable electrically conducting spring plates mounted to the button. The button includes a button cap including a relatively high durometer material and button walls including a relatively low durometer button material, such that the button walls collapse and the button cap generally maintains its shape when pressure is applied to the button cap. Each spring plate includes a plurality of cantilever springs. When the button is depressed, the cantilever springs of the spring plates come in contact with electrical tracks to complete a circuit. The completion of the circuit causes a signal to be sent to a vehicle computer, which signals a motor to release the automotive vehicle door latch.

  • Publication number: 20020020036
    Abstract: A multi-use floor tool, with which the same nozzle can be used in both dry and wet vacuum operation, and which allows for both wet and dry cleaning attachments to be easily attached and removed is disclosed. One such cleaning attachment for dry operation is a bristle brush which, when attached to the nozzle, is able to rotate, such that debris is collected with both the push and pull cleaning motions and such that for each motion, air flows primarily through the side of the nozzle at which debris is being gathered. The attachment for wet operation is a squeegee, which is rigidly attached to the nozzle having an insert which reduces the area of air flow into the nozzle and thereby increases the effectiveness of wet cleaning. This design increases the effectiveness of both wet and dry operation, and allows the operator to effectively clean in both wet and dry conditions while using the same nozzle.
