  • Patent number: 6796241
    Abstract: This invention relates to a method and apparatus for distributing mass copies of text and/or images on a novel medium, namely eggs, by using the eggshell of the egg as an advertising or message-bearing medium. Mass quantities of eggs are imprinted with a promotional image prior to distributing said eggs to consumers. The promotional image can be, for indicative of a modification to the egg's content, or consist of warnings or instructions pertaining to security or emergency matters. The shells of the eggs are imprinted by a method comprising the steps of (1) repeatedly transferring one row of eggs at a time from a carton having M rows of N eggs to N empty egg-receiving cradles until all the eggs in the carton has been transferred, moving the cradles through a number of imprinting stations, imprinting N eggs at each such station with N tampons, and transferring N imprinted eggs at a time into each of the M rows in the cartons.

  • Patent number: 6770016
    Abstract: The invention herein provides a “thick bar” barbell that permits free rotation of weight plates during weightlifting movements, weighs less than 50 lbs. and accommodates standard Olympic weight plates. Briefly, the invention comprising a generally cylindrical bar of generally annular cross-section having an outer diameter of between approximately 1.5 inches and 3.5 inches and extending longitudinally between a pair of end regions. A rod member is securely inserted within each end region of the bar. Each rod member has an outer segment extending longitudinally outward beyond the respective end region of the bar, the segment having an O.D. less than the O.D. of the bar. Generally cylindrical sleeves are mounted on the outer segments of the rod members for rotation thereabout the bar's longitudinal axis, with a bushing between each of the rod segments and the respective sleeve. The outer diameter of each sleeve is sized to accommodate the 50 mm hole found in standard Olympic weight plates.

  • Patent number: 5180936
    Abstract: An improved GaAs switching device is disclosed, of the type having a switched clamp which shunts pull-up current except during a portion of a "0" to "1" transistion at the device's output. The device herein provided enhanced immunity to interconnect resistance by isolating the gate-to-source Schottky diode of the clamp's FET from the device's output node. In accordance with the invention, the gate-to-source current through the clamp's FET is limited by an impedance device in the FET's gate circuit to provide the isolation.

  • Patent number: 5132644
    Abstract: A microstrip switch having a conductive path comprises a grounded waveguide cavity-defining enclosure. A movable switch member having first and second, separated, electrically conductive segments is mounted within a path-interrupting gap for movement between an open position and a closed position. The first conductive segment is always electrically coupled to the cavity enclosure. The second conductive segment comprises a cantilevered, springy member for contact with the conductive path on either side of the gap when the switch is closed. Single-throw and double-throw embodiments are described.

  • Patent number: 4461994
    Abstract: The tachometer of the present invention has a stator member with a pair of opposed stator elements. The stator member is mounted on the apparatus. Windings are provided on the stator elements in which the electric signal is generated.A magnetic means is provided for establishing a magnetic flux between the stator segments. For this purpose, magnets may be mounted on the exterior of the stator segments and the portions of the apparatus adjacent the segments used as the flux return path. Or, magnets may bridge the two stator segments.A magnetically permeable rotor is mounted on the apparatus shaft. The rotor may be formed of steel laminations with no rotating winding and has a plurality of peripheral projections that alter the reluctance of the magnetic path in the teeth as they rotate, inducing a speed responsive signal in the windings. The maximum speed of the rotor is limited only by the strength of the steel.

  • Patent number: 4432365
    Abstract: Disclosed herein is a physiological, electrically heated, thermostatically controlled sensing unit of the type used in the medical field for measuring blood contents, such as oxygen. A typical unit comprises a housing for application to the skin of a living being, an electric heater element within the housing, and a temperature-responsive switching circuit, also accommodated within the housing. The switching circuit automatically disconnects a power supply to the heater element when the skin temperature exceeds an adjustable predetermined threshold level. The power supply for the switching circuit is directly connected to the power supply for the heater element within the housing.

  • Patent number: 4425918
    Abstract: Disclosed herein is a retainer arrangement for applying a membrane to a physiological sensing unit for the transcutaneous determination of the magnitude of physiological quantitites, particularly for measuring the partial pressure of gases in blood or the like. The arrangement constitutes a preassembly of a membrane, with a clamping ring accommodating the membrane and having an annular recess receiving the rim of the membrane. The clamping ring has a lip in the form of an inwardly protruding annular edge for removably securing the clamping ring together with the membrane to the sensing unit by virtue of the lip resiliently snapping into a peripheral groove of the sensing unit, the lip defining the periphery of the annular recess. In accordance with the invention, an auxiliary retainer element, is provided for temporarily and removably assembling the membrane with the clamping ring prior to assembly with the sensing unit.
