  • Publication number: 20110155619
    Abstract: The present disclosure provides a method of manufacturing ceramic objects having glazed and unglazed surfaces and a multi-piece, selectively assembled ceramic object. The present disclosure overcomes the necessity of separately firing multi-piece ceramic objects, such as stoneware products, having both glazed and unglazed surfaces. In accordance with the present disclosure, a bowl having a fully glazed rim and a lid having at least a partially glazed rim can be fired with the lid in place covering the bowl. In this manner, more complete pieces can be fired over time resulting in greater throughput and energy savings. In addition, by firing the two pieces together, it is expected that there will be greater dimensional stability or less distortion than by firing the two pieces separately.

  • Patent number: 6796451
    Abstract: A cap for use on the threaded filler neck of a coolant reservoir, such as an automobile radiator, comprising a cover and main body and including: a means for transmitting torque from the cover to the main body to screw the cap onto the filler neck. The cap but for preventing excess torque from being transmitted. The cap includes a second torque transmission means for unscrewing the cap, which does not limit the torque that can be transmitted. The cap also includes a means for preventing the cap from being unscrewed when the coolant is under pressure; a pressure relief means to prevent the coolant pressure from exceeding a predetermined level; and a vacuum relief means for preventing the coolant pressure from falling below a second predetermined level.

  • Patent number: 6763966
    Abstract: A torque-limit signal cap for a filler neck includes a handle, a filler neck closure, and a torque-limit signaler. The torque-limit signaler operates during cap installation to interrupt temporarily a driving connection established between the handle and the closure to provide a tactile and/or auditory signal to a user turning the cap in the filler neck indicating that sufficient torque has been applied to the handle to seat the closure in a filler neck-closing position in the filler neck.

  • Publication number: 20020118763
    Abstract: A process for associating and delivering data with a video signal includes digitizing an analog data signal. The digitized data is then compressed and transcoded into a format compatible with a video source signal. The data is then inserted into unused video lines of the video source signal. The encoded video source signal is transmitted to a decoder where the inserted data is separated from the video source signal. The inserted data is then converted to its original form, and either visually displayed or audibly delivered to an end user. The invention can be used to associate and deliver audio narrative description with a video signal for the benefit of the visually impaired.

  • Patent number: 6415827
    Abstract: A closure assembly includes a filler neck, a housing, and an appearance cover. The housing includes a nozzle-receiving passageway and an interior region. A closure door is coupled to housing and prevents fuel vapor from flowing through passageway. A pressure-relief valve assembly is positioned within interior region and controls the flow of fuel vapor through interior region when the closure door is closed. A valve actuator is coupled to housing and includes a nozzle arm, a stem arm, and a conductor arm. Stem arm moves with nozzle arm and opens pressure-relief valve assembly when nozzle arm is engaged by a fuel-dispensing nozzle upon movement of a nozzle into passageway. A conductor arm is coupled to nozzle arm and is positioned to contact filler neck through an opening in housing. When a nozzle contacts the nozzle arm, any electrical charge present on the fuel-dispensing nozzle is conducted through nozzle arm and conductor arm to the filler neck.

  • Patent number: 6286704
    Abstract: A fuel cap has an upper housing and a lower housing, each configured to be inserted into the filler neck of a vehicle fuel system. The upper housing and lower housing are cooperatively configured to allow both rotational and axial relative movement with respect to one another. A seal coupled to the lower housing sealingly engages the filler neck when the fuel cap is in a tightened position. A spring mount is coupled to the lower housing and engages a spring that is positioned to bias the lower housing axially toward the upper housing to assist in loosening contact of the seal and filler neck during removal of the fuel cap. The fuel cap further has a drive axially spacing the upper housing from the lower housing as the upper housing rotates relative to the lower housing. A cam and cam follower connection between the upper and lower housing provides the drive.

  • Patent number: 6230549
    Abstract: A fuel cap leakage tester is provided comprising a fuel cap support, a pressure source, and a monitor. The fuel cap support is formed to included a test chamber and is adapted to receive a fuel cap to be tested in the test chamber to establish a pressurizable region, therein and a sealed connection between the fuel cap to be tested and the fuel cap support. The monitor is positioned to communicate with the pressurizable region formed in the fuel cap support and is configured to measure air pressure in the pressurizable region. The fuel cap leakage tester further comprises a system for communicating a flow of pressurized air from the pressure source to the pressurizable region with a predetermined pressure drop of the pressurized air therebetween. The monitor measures the pressure level of the pressurized air in the pressurizable region to determine whether the fuel cap to be tested meets or exceeds a predetermined leakage flow rate.
