  • Patent number: 6944272
    Abstract: A unified messaging system is configured to store and retrieve email, facsimile, pager, and voicemail messages. A telephone operated by a person is operatively coupled over a public switched telephone network to the unified messaging system. The system receives over the public switch telephone network a signal from the telephone corresponding to an administer multiple messages command for multiple messages having a common trait. In one form, the multiple messages having the common trait are then deleted from the database in response to this command. In another form, the multiple messages are filed into a folder specified by the person.

  • Patent number: 6851634
    Abstract: Methods and apparatus are provided for dispensing chemical material, and in particular, granular, agricultural material, from a moving device driven over terrain to be treated with the material. A metering system for dispersing the material includes on apertured metering disk positioned above a rotatable impeller. The apertured disk meters material from a product container, by gravity feed, onto the impeller below at a rate proportional to the linear speed at which the apparatus is driven to dispense material at a uniform density over the terrain. The metering disk is a component of a product container which is removably mounted to the device. The impeller rotates at a constant speed to disperse the deposited material at a uniform distance from the apparatus, and the position on which the material is deposited on the impeller is adjustable.

  • Patent number: 6482763
    Abstract: The present invention provides fuel cell electrode catalysts comprising alternating platinum-containing layers and layers containing suboxides of a second metal, where the catalyst demonstrates an early onset of CO oxidation. Preferred second metals are selected from the group consisting of Group IIIb metals, Group IVb metals, Group Vb metals, Group VIb metals and Group VIIb metals, most preferably Ti, Ta, W and Mo. The present invention additionally provides methods of making such catalysts, preferably by alternate deposition of platinum and second metals in the presence of substoichiometric amounts of gaseous oxygen.

  • Patent number: 5273610
    Abstract: An apparatus and method including a current sensor having a radiation emitter, such as an electrical resistor, and a radiation detector, such as an infrared detector, for sensing current flowing to a plasma generating electrode from a radio frequency (RF) power source. The resistor may include a high emissivity infrared coating to enhance efficiency of the current sensor. The infrared detector provides a highly accurate indication of the average or root-mean-square current delivered to the plasma generating electrode without introducing parasitic capacitance into the measurement, or sensing, circuit. A voltage sensor and a second current sensor, such as a torroidal current sensor, provide the voltage and phase angle of the current delivered to the plasma generating electrode to thereby permit calculation of the power delivered to the plasma generating electrode. A processor controls the RF source responsive to the sensed average current, sensed voltage, and sensed phase angle of the current.

  • Patent number: 5234193
    Abstract: An improved rotary plug valve of the type having a valve body with a fluid inlet conduit and a fluid outlet conduit therein has a rotary plug disposed for rotation in the valve body between an open position and a closed position. In the closed position the plug has a seat seal disposed in a groove in the cylindrical surface thereof which seat seal extends adjacent and surrounds the fluid inlet conduit to seal the inlet conduit against fluid flow. The groove in the plug has a radially inner wall, a radially outer wall and a base wall. The base wall extends at an angle so that the radially outer wall extends more deeply into the plug than the radially inner wall. Preferably the groove and the seat seal have an annular, cylindrical shape. Also preferably the seat seal has a shape so that a pressure space is formed adjacent the base wall of the groove and a gap is formed adjacent the radially inner wall of the groove. Fluid pressure in these urge the seat seal into sealing positions.

  • Patent number: 5166256
    Abstract: A binder for use in gravure printing ink formulations comprising a modified rosin ester resinate prepared by forming a rosin-dienophile adduct, reacting the adduct with a polyfunctional hydroxy compound to form an ester and reacting with an acrylic-containing polymer to form a hard rosin ester. The polymer-modified rosin ester resinate is formed by reacting the prepared hard rosin ester with a rosin-dienophile adduct and an acrylic-containing polymer, reacting the product thereof with reactive zinc, followed by a reaction with lime, dehydrating the resinate product by refluxing, and adjusting its viscosity with a hydrocarbon solvent.
