Title: Process for producing self-adhesive sheet materials
Inventor: WARWICK PETER
IPC: B26D9/00
Filed: 1991-08-13
Granted: 1998-04-21
Abstract: A process for providing lengths of self-adhesive strip materials as laminates comprising in sequency the substrate (3), adhesive (4) and release sheet (5) in which process the laminate is first subjected to a cutting operation in which the substrate is cut through with a die (8) without cutting through the underlying release paper, to form a product strip which is continuous in the machine direction, the laminated strip is then severed (17) in the cross direction through its entire thickness and reeled off to form product rolls. Preferably the starting material is converted into several parallel machine direction lengths of product (18) separated by cutting the substrate through its entire thickness and perforating the release sheet (15), winding the product roll as a single roll and then snapping apart adjacent strips at the perforations. The substrate is usually a polyvinylchloride web. The product is suitable for use in home decorating.

Granted: 2003-01-07
Abstract: A measuring vessel for holding liquids such as blood, blood plasma, or the like that are to be analyzed. The measuring vessel incorporates a shaft that is of rectangular cross-section. One end of this shaft forms an inlet opening and the opposite end area is formed as a funnel that opens out into a tubular section. The tubular section incorporates at least two parallel side surfaces that extend to almost the whole length and the end of the tubular section is closed off by a bottom. The wide sides of the shaft that extend parallel to each other each form a flat contact surface. There is a part of foot elements connected with the tubular section on which the measuring vessel can be stood. The bottom of the tubular section is formed with a circular internal base area and a central stud which foams a track for a ball with the help of which the coagulating characteristics of blood can be measured.

Granted: 1997-03-18
Abstract: An apparatus and technique for fluid level determination in automatic transmissions. The invention employs an electronic control unit in association with an automatic transmission for a vehicle, the electronic control unit receiving data corresponding to transmission oil level, transmission oil temperature, engine speed, transmission speed, and transmission selected range. Upon determining that such data satisfies certain diagnostic tests, the level of transmission fluid within the transmission is determined and adjusted or otherwise normalized to ideal test conditions. The electronic control unit compensates an oil level signal for deviations in oil temperature from an optimum test temperature, and makes further compensation for deviations in engine speed and settling time at the time that the test data is acquired. Additionally, variations in oil density as a function of oil temperature are also compensated.

Abstract: A method of measuring in small samples the ultra-trace amounts of C-14 relative to C-12,13 in a background of N-14, comprises the following steps: the sample isphysically and chemically processed depending upon the final sensitivity desired; the sample is injected into an ICP, which functions as a source of positive ions with energies up to a few tens of KeV, and as a molecular dissociator of order parts-per-trillion; the ions then analyzed with conventional Electrostatic and Magnetic spectrometers, which monitor the ion beams with adjacent masses and transmit the ion species of interest through defining apertures; the transmitted ions are re-foccused and accelerated to an energy of order tens of KeV; the positive ion beam strikes a thin foil or supersonic gas-jet canal where some of the beam intensityemerges with negative charge, eliminating atomic isobar backgrounds that cannot form negative ions, and as an additional molecular ion dissociator; the transmitted Negative ions are refoccused and accelerated by a few more tens of KeV; the ionsare then analyzed with conventional Electrostatic and Magnetic spectrometers, through a final defining aperture and onto a detector. Similar configurations may be used to measure ratios of other long-lived radio- to stable-isotopes whose com-peting stable atomic mass-isobars cannot form negative ions, such as: 26Al/27Al in a background with 26Mg; 55Fe/54Fe in a background with 55Mn; 129I/127I in a background with 129Xe, Similar configurations may be used for direct measure of platinum group elements (PGE), actinides (ACT), etc., when atomic-isobars need not be distinguished.

Abstract: Bytes of different types of digital information, including standard interframe video (SIF), graphics, television and audio are transferred between a controller, storage memory and shift registers (e.g. FIFO's) individually associated with the different information types. For a VRAM memory, information is transferred in parallel, controlled by tag bus information, from the controller to the memory and then serially to the FIFO's, all at a frequency higher than a clock frequency in a monitor raster scan. The tag bus information is decoded and introduced to an additional FIFO. A state machine processes such additional FIFO information and transfers the digital information to the different FIFO's at times controlled in each line by such additional FIFO- e.g. particular times in each line for the SIF and graphics and thereafter, for television and audio, at times unrelated to any times in such line. The graphics transfer is timed to substantially fill, but not overflow, in such line the limited capacity of the associated FIFO. Their limited capacities cause the television and audio FIFO's to stop receiving bytes when filled to particular limits. For a DRAM memory, information is transferred, dependent upon the tag bus information, in parallel between the controller, memory and FIFO's at the clock frequency. In a "Rambus" system, a bus common with the controller, memory and FIFO's provides control and timing bytes. The information in successive bytes transferred through the common bus to the controller, memory and FIFO's dependent upon such timing and control information in such bytes.

Abstract: A lock mechanism has a cylindrical housing with an axial bore therethrough, and a key-controlled core rotatable within the bore between locked and unlocked conditions and removable from and installable in the bore in the unlocked condition. The core has a plug at its rear end which is mateably engageable in a socket on the front face of a shifter, for rotating the shifter within the bore in response to rotation of the core, and thereby operating a latch member coupled to the shifter. A radial tab on the housing is receivable in an arcuate groove formed in the outer surface of the shifter for limiting rotation of the shifter to facilitate retention of the shifter in the single rotational orientation upon removal of the core from the housing. An O-ring on the shifter frictionally inhibits rotation thereof.

Abstract: A processor outputs a state signal representing the process state to a reset circuit.  Upon reception of a reset signal from an external reset switch, the reset circuit outputs the reset signal to the reset terminal of the processor under the condition that the state signal allows a reset operation.  The reset circuit also has a counter for starting a count operation upon reception of an externally input reset signal.  Even when the processor is in a runaway state and cannot output the state signal for allowing the reset operation, a forced reset signal is supplied to the processor after a predetermined time is counted by the counter.
