Abstract: Liquid-crystal switching and display devices have recently found numerous novel areas of application, for example for flat display screens. For optimum operation of the LC display, a uniform layer thickness of the liquid-crystalline material is of considerable importance. In order to ensure a uniform layer thickness, spacers are employed in the display. In the present liquid-crystal display, these spacers comprise elevations of at least one of the outer plates (made of glass). These elevations have a height of from 0.1  mu m to 0.1 mm and are obtained by a targeted, streak-free etching process. The process for etching the outer plate(s) comprises, as part steps, inter alia the application of an etch-initiation layer (for example, made of titanium), the application of an etch-stop layer (for example made of gold) and the actual etching operation (for example by means of aqueous hydrofluoric acid). The displays according to the invention can easily be filled with nematic and smectic LC materials and are mechanically very stable.

Abstract: 2.1 In known video recorders, a signal reproduced from the magnetic tape is supplied to a television receiver connected to the video recorder either via a radio-frequency modulator and a first output socket for a radio-frequency signal or via a second output socket for a video-frequency signal. A problem occurring in practice consists in that the channel to which the frequency of the said radio-frequency modulator is set can be occupied by a transmitter which leads to moire disturbances in the picture reproduced. For this case, a rotary knob, by means of which the frequency of the radio-frequency modulator can be set to a different channel, is provided at the rear of known video recorders. 2.2 In the new video recorder, the radio-frequency modulator can be disconnected so that, when the television receiver is connected to the video recorder via its second output socket, the occurrence of moire interference caused by the radio-frequency modulator is basically eliminated. 2.3 Video recorders. <IMAGE>

Abstract: A filter cartridge is described for filtering highly viscous fluids, for example polymer melts, which cartridge can be disassembled into a plurality of components and in which the filter sock is firmly attached to a cap and both parts may be changed together. By means of the complete avoidance of threaded components, the filter cartridge can be produced in very small sizes. At the same time, it may be more easily disassembled and cleaned even when contaminated by solidified melt residues. If it becomes unusable, individual components may be rapidly changed. By means of a plug-in connection to a base plate, the whole filter cartridge is rapidly detachable from the base plate.

Abstract: The present invention provides a hydraulic sensor for quench detection and location in a superconduc­tor, and particularly a superconductor used to form an inductor or a magnet. The sensor consists of an insulat­ing tube (1) adjacent to and preferably co-wound with the superconductor (2) and filed with a supercooled working fluid. When joule heating occurs in the superconducting conductor as a result of a portion of it becoming normal, the heat is transferred directly to the corresponding portion of the adjacent tube (1). This heat causes the vapor pressure of the working fluid at that point in the tube to change. This change in pressure propagates in both directions at the speed of sound in the working fluid. By detecting with sensors (6, 7) when a change in pressure arrives at the ends (5, 6) of the tube (1) and calculating the difference between the arrival times, not only can a quench be detected, but the exact location of the quench initiating region can be determined.

Abstract: A metering system includes an electronic register having a non-volatile storage into which data is written upon the detection of a power outage. A power supply and monitor provides a regulated voltage for the electronic register and contains a capacitor which normally stores a sufficient quantity of electric energy to continue operation of the electronic register for a long enough period of time to complete the writing of data to the non-volatile storage. The discharge rate of the capacitor is linearly controlled to sustain the regulated voltage at its normal regulated value for the required period of time. An electronic meter is shut down upon the detection of a power outage to remove a portion of the load on the power supply to aid in sustaining the regulated voltage for the required period of time. The detection of momentary power outages is prevented by forcing the capacitor to charge to a prescribed voltage level before a subsequent outage can be detected. The capacitor is also forced to maintain a minimum charge between momentary power outages which is sufficient to sustain the regulated voltage for the required period upon the detection of a non-momentary power outage following a previous momentary outage which caused the capacitor to discharge below its minimum charge.

Abstract: Method and apparatus for processing on-line operands A, B and C to produce the arithmetic expression S = (A × B) + C. In general, the apparatus comprises an input processing unit, an on-line multiplication unit, and an on-line serial addition unit. The input processing unit is for sequentially introducing the digits of operands A, B and C into the apparatus, where each digit is represented in a redundant binary number format. The multiplication means multiplies the sequence of digits of the operands A and B to produce the n-th product digit p n  of the product P = A × B, with the most significant digit p 0  being computed first. The on-line addition unit adds the n-th product digit to the n-th digit of on-line operand C, so as to produce the n-th digit s n  of the arithmetic expression S = (A × B) + C, with the most significant digit s 0  being produced first. In one embodiment, the input processing unit comprises a selective conversion subunit for selectively converting the digits of operands A, B and C sequentially entering the computational device, so that each digit is represented in a redundant number format. In such an embodiment, the redundant binary number format is characterized by signed digit numbers, and the selective conversion subunit comprises a binary-to-signed digit converter. Also, the input processing unit preferably includes a word-length control subunit for restraining the word length of the operands and intermediate words to a predetermined limit. In yet another embodiment, the apparatus hereof includes an arithmetic performance testing system for determining whether or not the arithmetic processor is functioning properly.

Abstract: A vehicle body pillar has a cavity (30) therein through which air flow creating undesirable noise and in which moisture and fluids such as water are not to be collected. An expandable sealant plug (34) is inserted therein and retained in place. The sealant material forming the plug is later expandable under controlled conditions. It is preferably expandable under temperatures of about 130°C to 205°C over a period of time. Preferably during the electro-coated paint baking and curing operation, the sealant is exposed to appropriate temperatures for sufficient time to expand the sealant about 800% and cure it, sealing the cavity (30) so as to prevent the flow of air through it. The expanded sealant also effectively blocks the intrusion of fluids such as water, minimizing corrosion within the pillar (Fig. 2).
