  • Patent number: 6691665
    Abstract: An air induction arrangement 7 for a variable displacement engine is provided. The air induction arrangement 7 includes first and second plenums 22, 24 fluidly connected to respective first and second throttles 26, 28. The first and second throttles 26, 28 are connected to respective first and second inlets 44, 60. In partial operation, the air induction arrangement 7 induces air into the first plenum 22. In higher power demand operation, the air induction arrangement 7 additionally induces air through the second plenum 24. There is a reduction of the cancellation of acoustic output between the first and second inlets 44, 60 so that an acoustic output of the engine 14 operating with only a first group of cylinders 16 is similar to the acoustic output of the engine when the engine is operating with both groups of cylinders 16, 20.

  • Patent number: 6573904
    Abstract: A method and apparatus in a data processing system for updating a buffer containing display information used to display pixels from a first layer and a second layer on a display in the data processing system. Display information is identified for pixels in the first layer in a region corresponding to a removal of pixels being displayed in the second layer. This identification is performed using a data structure containing display information for displaying pixels in the first layer and pixels in the second layer to form identified display information. Display information in the buffer is updated using identified display information.

  • Patent number: 6529208
    Abstract: A method and apparatus in a data processing system for updating a buffer used to display pixels from a first layer and a second layer in the data processing system, wherein identification display information for pixels from the first layer and the second layer are stored in the buffer. Pixels are identified for the second layer having opaque pixel types to form a selected set of pixels. Overwriting of display information is prevented for the selected set of pixels in the buffer when updating the buffer.

  • Patent number: 6296455
    Abstract: A pump enable system includes a variable-displacement piston pump having a displacement control device. The displacement control device controls displacement of pistons in the pump based on a position thereof, and a position control system in the pump controls a position of the displacement control device based on a load on the pump. An over-ride system selectively over-rides the position control system such that the displacement control device assumes a position which reduces displacement of the pistons in the pump.

  • Patent number: 6006722
    Abstract: An air control valve for an engine includes a throttle body defining an air intake passage and a throttle valve rotatably mounted in the passage. The range of valve rotation includes an idle control portion extending from a minimum air flow position to an intermediate air flow position and a power control portion extending from the intermediate air flow position to a maximum air flow position. The intake passage is defined by an internal wall of the throttle body having a pair of arcuate surfaces spaced from the valve periphery, at a maximum first radius from the valve axis, with gradually increasing clearance on opposite sides of the valve axis in the idle control range from the minimum to the intermediate air flow position of the valve. The arcuate surfaces are defined by second and third radii greater than the maximum first radius and centered on second and third axes spaced laterally of the passage a predetermined offset distance beyond the valve axis relative to their respective surfaces.

  • Patent number: 5935052
    Abstract: An adapter for use in a fixed angle centrifuge rotor has, in use, a radially inboard and a radially inboard portion. An opening is formed in the radially inboard portion of the adapter. The opening is sized so that substantially no part of the inboard portion of the adapter is exposed during centrifugation to a load that exceeds the ability of the material of the adapter to support itself. The material of the inboard portion of the adapter surrounding the opening has sufficient strength to support itself while under centrifugation. The adapter is fabricated from a light transmissive material. A plug that is slidably disposed and selectably positionable within the opening in the inboard segment of the adapter. The inside surface of the plug having a sealing material thereon that is biased into contact with a tube carried within the adapter.

  • Patent number: 5861089
    Abstract: A process for separating an emulsion into separate and easily recoverable phases. The process comprises exposing an emulsion comprising a discontinuous phase and a non-conducting continuous phase to an electric field thereby effecting coalescence of the discontinuous phase into droplets of a size for effective gravitation from the continuous phase, where the discontinuous phase and the continuous phase have different dielectric constants and densities and at least one of the phases comprise a silicon containing compound or a silicon containing polymer. The present process is especially useful for separating emulsions where the discontinuous phase is an aqueous acid solution and the continuous phase is diorganopolysiloxane.

  • Patent number: 5780798
    Abstract: A sensing unit to be positioned between the matress of a bed and the bed frame for monitoring an occupant of the bed, the sensor consisting of thinly spaced upper and lower steel plates between which is located a point sensor such as a Hall effect transducer or a reed switch. The upper plate flexes in response to the weight of an occupant above. The sensing unit is to be attached to a control unit which generates an audible and visible alarm signal when the occupant leaves the bed. In a different embodiment, sensors are located in the bed frame to monitor the occupant of the bed.

  • Patent number: 5647679
    Abstract: A thermal printer for printing on a continuous print medium by ink transfer from a thermal print ribbon has a print head which is pivotally mounted and which is driven in an oscillatory nodding motion by a stepper motor so as to repeatedly to bring a linear array of energizable printing elements to bear against a platen roller. Both the element array and the platen extend transversely to respective paths of travel of the print medium and the ribbon. The print medium is fed through the printer from an inlet region, between the platen and print head, and thence to an outlet region. The instantaneous rate of travel of the print medium past the print head is substantially the same as the rate of feed of print medium to the printer. Typically this rate is of the order of 250 to 400 mm per second. The ribbon also travels between the print head and the platen, overlying the print medium and is driven in such a manner that it travels at the same rate as the print medium during each printing operation.

  • Patent number: 5643350
    Abstract: A glass melter for vitrifying material including radioactive and hazardous materials. In one embodiment, the melter comprises an inner vessel or container having a solidified glass skull, at least one pair of vertically-oriented, retractable electrodes, a first wall spaced apart from said inner vessel to define a dry annulus therebetween for radiatively cooling the inner vessel, and a second wall spaced apart from said first wall to define a second annulus that serves as a water jacket when filled with water. Each electrode has a protective sleeve therearound with means formed therebetween for passing a purging gas therethrough. A central access nozzle allows waste material and glass formers to be fed into the inner vessel while simultaneously venting the off-gas generated in the inner vessel. Also, the dry annulus can have fluid circulating therethrough for regulated cooling or leak detection.

  • Patent number: 4006215
    Abstract: Sulfate solutions containing at least one valuable metal from the group: Fe, Ni and Co, particularly solutions resulting from the leaching of lateritic ores or concentrates, are treated to recover the valuable metal. The latter is precipitated by treating the solution with magnesium hydroxide. The resulting magnesium-containing solution is treated with lime under controlled conditions to precipitate relatively fine particles of magnesium hydroxide and relatively coarse particles of gypsum. The difference in particle size is relied on to separate the magnesium hydroxide (for recycling) from the gypsum (which is calcined to regenerate lime).
