  • Patent number: 5930864
    Abstract: An upright vacuum cleaner includes a main body, a floor nozzle unit, and a float plate or float unit. The main body has a motor fan for generating a suction force and a dust-collection chamber for collecting dust. The motor fan provides the suction force to the dust collection chamber. The floor nozzle unit is disposed under the main body. The floor nozzle unit has an inlet port connected to the dust-collection chamber for attracting dust on a floor into the dust-collection chamber by the suction force of said motor fan. The float plate or float unit is disposed on a lower face of the floor nozzle unit. The float plate or float unit includes a floor opposing face where an outlet port is formed for spouting discharge air to the floor from the motor fan. The float face is located around the outlet port to receive a lifting force produced by pressure of the discharge air between the float face and the floor to be cleaned.

  • Patent number: 5928195
    Abstract: A remotely controlled drug delivery device administers a dose of a drug, agent or microbicide using a gas pressure delivery system. The device stores multiple doses of the drug or agent. A toroid shaped housing includes three chambers, a gas chamber containing a pressurized gas, a drug storage chamber containing the drug or agent, and an expandable chamber for delivering the drug from the drug storage. The device includes an electronic controller for opening a valve connecting the gas chamber to the expandable chamber for a predetermined period of time in order to deliver a predetermined dose of the drug. The controller communicates with a remote control device via radio frequency. The remote control device sends a signal to the controller, which causes a dose to be delivered. The controller returns a signal to the remote control device indicating that the dose has been delivered and a signal indicating when the device needs to be removed for maintenance.

  • Patent number: 5924910
    Abstract: A toy vehicle includes a chassis and a pair of shell halves rotatably attached to the chassis, which in a first position form a vehicle body that bounds an interior space. A four-bar linkage is attached to the chassis and is disposed at least partially within the interior space. A pair of external finger tabs is pivotally attached to the chassis and connected with the linkage by means of pinion gears and a rack. Movement of the finger tabs together drives the linkage to raise and project a simulated weapon on the linkage and releases the shell halves to separate. Reverse movement of the tabs reverses the operation. A second toy vehicle includes a chassis and a pair of rotatable body panels and a different four-bar mechanism attached to the chassis beneath the body panels in a first position. A pair of external finger tabs is pivotally attached to the chassis.

  • Patent number: 5926616
    Abstract: The horizontal resolution of an input dot image is multiplied by an odd integer m, greater than unity, to produce an intermediate image. The intermediate image is smoothed by logic operations to form a final image, which is printed at a horizontal resolution equal to the horizontal resolution of the intermediate image divided by two. The horizontal resolution of the input dot image is therefore multiplied by a half-integer value (m/2) in the final image. The vertical resolution of the final image is twice the vertical resolution of the intermediate image, but may be adjusted by reducing the space between raster lines if necessary, so that the image can be printed on one page.

  • Patent number: 5924204
    Abstract: A hand-held scraper tool having a handle and a blade clamp and having a blade whose cross-section is in the shape of an arrowhead on a shank. The arrowhead shape of the blade has a blunt rear end that is sufficiently thick to deflect scraped material away from contact with the region of the blade clamp gripping the shank, to provide improved scraping efficiency and to minimize damage to the underlying substrate. The method of using the scraper blade and scraper tool is also within the scope of the invention. The invention avoids the problem common to prior art scrapers which are susceptible to chips or pieces of the scraped material becoming jammed between the blade and the gripping jaws of the scraper tool, causing blade misalignment that results in incomplete scraping and/or damage to the underlying substrate.

  • Patent number: 5926213
    Abstract: The invention relates to a device for correcting the tone of color pictures recorded by a video camera, in particular an endoscope camera. A control device, which may also be part of a digital video camera, comprises a memory for storing a table which indicates a characteristic adjusting curve for tone correction values. The control device may further comprise an interface for inputting one or more characteristic adjusting curves according to the field of application of the device according to the invention. A simple rotary transducer which is connected via a lead to a control device serves as the input medium for the tone correction. After activating an automatic white balancing by way of a key connected to the control device, the correction values lies at the white point. The white point is always located on the adjusting curve and serves as a starting point.

  • Patent number: 5922203
    Abstract: Water permeable reverse osmosis membranes are prepared by interfacially polymerizing on a microporous support an essentially monomeric polyamine reactant having at least two amine functional groups per reactant molecule, and an essentially monomeric amine-reactive polyfunctional aromatic or cycloaliphatic acyl halide having on the average at least about 2 acyl halide groups per reactant molecule. The polymerization is optionally carried out in the presence of a monomeric amine salt, which increases the flux rate of the resulting membrane. Preferred polyamine compounds of the generic formula, which are novel per se, include 3,5-diaminobenzoyl piperazine, 4-aminobenzoyl piperazine, 3-aminobenzoyl piperazine, isophthaloyl piperazine, and terephthaloyl piperazine.

  • Patent number: 5922402
    Abstract: A method of manufacturing adhesive tape by applying a coating of liquid adhesive to a surface of a continuous web substrate moving in a longitudinal direction to create an adhesive-free zone on the web substrate that extends in a longitudinal direction between areas of adhesive coating on the web substrate and by contacting the surface of the moving continuous web substrate carrying the applied liquid adhesive coating with a rotating metering rod to obtain an adhesive coating with a predetermined specific thickness, wherein the metering rod has an elastomeric wiper contacting the rod and wiping the rod at a location along the length of the rod that corresponds to the transition between the adhesive-free zone and the adhesivecontaining zone on the coated web substrate, to prevent edge buildup of applied adhesive at the transition on the coated web substrate.
