An accessory (40) for a computer mouse (18) includes a multistrand accessory conductor (42) for transmitting location signals and acceptance signals having a first coupling (44) for coupling a first end of the conductor (42) to the coupling (26) of a computer mouse assembly (19) and a second coupling (46) for coupling a second end of the conductor (42) to a coupling (22) of a computer (10). The accessory further includes a remote acceptance switch (54) coupled to the strands of the multistrand a...

A sink attachment having a basin, a drain tube, and a sealing member is disclosed. The sink attachment provides for simultaneously draining tap water or other liquids and sealing the sink. The attachment may be relocated without having to remove the sealing member from the sink drain.

Rotary raking implements of a hay tedding machine are mounted at the ends of a central beam and at the ends of a pair of outer support beams pivotally extended from the central beam. Endless drive belts drivingly interconnect the outer raking implements with those at the ends of the central beam and are supported substantially in planes common with the horizontal axes about which the outer support beams are vertically displaceable relative to the central beam, establishing a continuous and yield...

An electrophotographic method is disclosed which produces multiple electrophotograhic copies from the same electrostatic image by multiply cycling the electrostatic image through development and transfer steps. To reduce copy density losses in subsequent copies, the biasing potential applied across the development zone is reduced on subsequent cycles of the electrostatic image through the development zone.

There is disclosed micro-processor controlled bio-fluid assay apparatus wherein microtitre plates are on carriers having machine readable labels and wherein the samples of bio-fluid and reagent dispensers also preferably carry machine readable labels whereby the micro-processors which controls movement of the plates through the apparatus can verify correct operation thereof. Movement of the plates is effected by a plate carrier transfer mechanism which has the ability to move the plate carriers ...

Imaging systems and methods are described. In one aspect, an ink layer having an electrorheological fluid composition including a suspension of colorant particles dispersed in an electrically insulating carrier fluid is formed on a surface. A charge image is projected onto the ink layer to selectively form charge-stiffened regions adhering to the electrically insulating layer and representing respective regions of the projected charge image. Non-charge-stiffened ink layer components are physical...

Apparatus and methods of applying a preformed conical heat-shrinkable plastic label to a container is disclosed to provide a tamper resistant cover, the label being applied by a transfer arm and head that rapidly supplies labels to the containers with a woodpecker-like action. There is also disclosed the novel container and cover therefore, the conical label being efficiently applied to the container and easily heat shrunk thereon.

Inlet air for a water heater used in a trailer home or camper is provided through an air tube passing through the floor of the camper to the heater within the camper. The lower end of the air tube terminates short of the ground beneath the camper and includes a cup assembly arranged to rotate about the axis of the air tube. The cup assembly has a front opening and a rear rudder. Wind blowing under the trailer home or camper will orient the cup assembly so that the front opening faces the wind so...
