Abstract: According to the invention, a discharge path (9) is formed in a gas-discharge switch having a cold-cathode low-pressure gas-discharge between the cathode (2) and an anode (3) in a central discharge region of a discharge chamber (8). The maximum internal height of the discharge chamber (8) determines the length d of the discharge path (9). The inner surface of the discharge chamber (8) is closed in the discharge region. The cathode (2) is provided with at least one opening (4, 5) outside the discharge region. In consequence, a gas-discharge switch is produced having a short time delay and low jitter as well as a low voltage dependency at the same pressure. …<IMAGE>…

Abstract: In a skeining device for skeining wire (26) fed to a coil winding apparatus, a shuttle member (23;23A) loops the wire around front and rear retaining members (13,14) and the loops are then twisted to form the skein. The wire (26) is under greatest tension when being pulled from the rear retaining member (14) to the front retaining member (13) and so the shuttle member (23;23A) is driven at a slower speed during this part of the skeining operation. Also the shuttle member (23;23A) is reversible along its path to allow optimum positioning of the shuttle when twisting the skein and when the wire passes rapidly through the device during coil winding.

Abstract: Es wird ein Messgerät vorgeschlagen, das verglichen mit herkömmlichen Höhenmessgeräten wesentlich mehr Messmöglichkeiten aufweist. Insbesondere ermöglicht es zusätzlich zu den Messungen in der Z-Achse Messungen in der Horizontalebene, die Vermessung schräg stehender prismatischer Körper, die Bestimmung von Neigungswinkeln und die Definition von Bohrungen und Zylindern durch drei oder mehr Punkte. Durch das Zusammenwirken von zwei Messsystemen (MS1, MS2) kann die bei einer Messung zu bewegende Masse sowie die erforderliche Auflagekraft der Messsonde (10) bedeutend reduziert werden, wodurch sich das Messgerät für automatisierte Messzyklen eignet. Auf einer Säule (3) aus vorteilhafterweise keramischem Werkstoff wird ein Schlitten (6) vorteilhafterweise mittels eines Magnetlagers verschiebbar positioniert und die Verschiebung mit einem Messsystem (MS1) gemessen. Die Verschiebung der Messsonde (10) gegenüber dem Schlitten (6) wird durch zumindest ein zweites Messsystem (MS2) gemessen. Die Signale beider und gegebenenfalls weiterer Messsysteme werden einem Rechner (26) zugeleitet, der sie nach vorbestimmten Kriterien individuell oder in Abhängigkeit voneinander auswertet. Über eine normierte Schnittstelle ist das Messgerät und/oder der Rechner (26) mit einem frei programmierbaren Rechner (28) oder Peripheriegeräten verbindbar.

Inventor: HARRISON CLARENCE
IPC: G06K7/00
Filed: 1991-02-04
Abstract: A two-frequency data signal, also known as a biphase or F/2F signal, is accurately decoded by sampling the signal and digitizing the samples to provide a series of digital values representing the signal. An intelligent digital filter manipulates the digital values to decode the signal, by detecting the peaks in the sampled signal and decoding the signal by analyzing the location and amplitudes of the peaks. Only peaks which are outside a guard band may be detected. If the signal cannot be properly decoded with a wide guard band, the guard band may be repeatedly narrowed, until a minimum guard band is reached. 
     Bits are identified by comparing the displacements between peaks to a bit cell width. An even number of displacements indicates a '0' bit, and an odd number of displacements indicates a '1' bit. Once a bit is decoded, the bit cell width is incremented by a predetermined amount if the bit cell width is wider than the current bit cell width, and is decremented by a predetermined amount if the decoded bit cell width is narrower than the current bit cell width. If no peaks are found within a maximum allowable bit cell width, this area is delimited as bad. An attempt is made to decode the bits in the bad area by analyzing all peaks without regard to a guard band. After decoding, the bits are converted into bytes. Parity and longitudinal redundancy code checks are used to correct bad bits. 
     During decoding, many indications of a degraded signal may be obtained. If a degraded signal is indicated, the host computer is notified, even though the signal was properly read. Card replacement can then be initiated at the first signs of signal degradation, before the data signal becomes unreadable.

Abstract: A method of reshaping a tube blank of amorphous, in particular glassy material without tools to form a rod by collapsing is known, in which method an underpressure below atmospheric pressure is maintained in the tubular part by continued evacuating during the collapsing, the blank being fed continuously, at a predetermined rotational rate, horizontally to a heating zone and its viscosity reduced there to such an extent that, owing to the difference in pressure between the underpressure and the outside pressure acting on the blank, the blank collapses in a collapsing region to form the rod and the rod is continuously drawn off, at a predetermined rotational rate, from the collapsing region. In order to produce homogeneous rod-shaped bodies from blanks in one operation and inexpensively by such a method, the outside dimensions and inside dimensions of the blank, the viscosity of the glassy material in the collapsing region, the difference in pressure between the underpressure and the outside pressure, the level of the underpressure, the drawing-off rate of the rod and the feeding rate of the blank as well as the rotational rates of rod and blank are chosen such that a stem of smaller cross-sectional dimensions than those of the rod is formed from the collapsing region counter to the drawing-off direction of the rod in the axis of the blank.

Abstract: In order to drive gates, in addition to the elements which carry out the work, such as circulating chains etc., electrical drive units are known in which an electric motor, a transmission unit and further control elements are accommodated inside a housing which consists of a baseplate and housing and is screwed to the cover etc.. In this case, it is also known for the limit switches, for the approach to the limit positions of the gate, to be accommodated inside the housing. In order additionally to define points at which the moving door actually changes over from high speed to slow speed, time-dependent controllers were used in the past. In order to increase the adjustment capability and the ease of repair, it is intended to implement all four positions by electromechanical limit switches. To this end, in addition to the previously known two limit switches which were mounted on the baseplate (1) in addition to longitudinally moving control elements, two such limit switches are also accommodated in a suitable depression (27) in the baseplate (1) under the control elements and are held in position by retaining parts which are mounted and screwed on with the aid of the two other limit switches. <IMAGE>
