Patent EP-0339232-A2 (EP)
Inventor: CALKINS RICHARD W
IPC: D06M13/08
Filed: 1989-03-14
Abstract: A method of producing a low cost impregnated and coated fiber useful in forming pump, valve, expansion joint, hydraulic cylinder and similar packings capable of resisting high caustic concentrations is provided. In accordance with this method a relatively low cost yarn, such as rayon, is simultaneously subjected to a spreading operation and passed through a highly alkaline tetrafluoroethylene (TFE) solution. As the yarn fibers are spread from a fiber bundle to a flat ribbon-like array of spaced parallel fibers, the fibers swell or "balloon" thus allowing the TFE to completely penetrate the interior of each fiber. A subsequent coating step insures that the exterior of each fiber is completely coated with the TFE solution. Fibers produced according to the present process are characterized by substantially lower cost than available materials, are completely caustic resistant at a pH approaching or exceeding 14, and have a long, useful service life in a variety of different environments.

Abstract: Regulation of an AC or DC voltage is achieved by processing a major portion of the prime power through a square wave inverter and a small portion of the prime power through a pulse width modulated switching regulator. The methods of regulation generally comprises the steps of: processing the unregulated input voltage to provide an output voltage; regulating an unregulated portion of the input voltage in response to a feedback signal indicative of the output voltage to provide a regulating voltage; and combining the regulating voltage with the output voltage to generate a regulated output voltage. The regulator circuit includes a square wave inverter circuit that produces a voltage in an output transformer, while a pulse width modulator regulates the output voltage in response to a feedback signal. The regulation is accomplished by pulse width modulating the portion of the input voltage that is unregulated, and applying this modulated voltage to a second transformer that combines the pulse width modulated voltage with the primary voltage in an AC fashion to produce the regulated output voltage. The invention improves the efficiency and reduces the weight and complexity of conventional voltage regulating devices.

Abstract: The invention relates to a method and a device for checking a dental impression for undercut tooth or tooth-stump surfaces and/or identical insertion paths for bridge members and/or for measuring tooth widths, tooth spacings or the lengths of dental arches. 
<??>In order to be able to establish, without great expenditure in terms of apparatus and materials, undercuts and/or dissimilar insertion paths of adjacent tooth-stump surfaces as a recording basis for bridge members or lengths and spacings, it is proposed to illuminate each worked tooth or tooth-stump with a light-beam bundle of circular cross-section having a beam direction essentially perpendicular to the impression plane. Thus, undercuts can be established on the basis of shadow images, and uneven surface inclinations can be established on the basis of different light-spot projections. The lengths and spacings to be calculated are determined by measuring the path covered by the light-beam bundle.

Title: Apparatus and method for reading, writing and refreshing memory with direct virtual or physical access
Inventor: HORST ROBERT W
IPC: G06F12/10
Filed: 1990-07-02
Abstract: A computer memory system is provided. Received memory requests can be for addresses which are virtual or physical. The type of address is determined, and a virtual/physical bit is set and stored. At least row address bits are compared to one or more registers which contain either a virtual or a physical row address, corresponding to a row addressed by a row address latch. When there is a hit with respect to one of these registers, column address bits are used to select the requested memory element, without the necessity for a virtual-to-physical translation. When there is a miss on all registers, a physical address is obtained, either from the requested address when this is physical, or from a virtual-to-physical translation. The physical address is used to load a new row address into a row address latch. Some column address bits are changed only when there has been a miss. A refresh cycle is described, which includes reading back into a row address latch the same row address which occupied the row address latch before the refresh cycle, thus preserving locality information or structure.
