Abstract: Bei bekannten Treibapparaten für Walzbänder, insbesondere für Warmbandhaspeln in Breitband- Walzenstraßen, ist die obere Treibrolle schwimmend in Führungen der Schwinge gelagert, während die untere Treibrolle im Ständer fest in der Horizontallage in Lagern gehalten ist. Die obere Treibrolle wird dabei durch Pneumatikzylinder auf der Antriebs- und Bedienungsseite oder durch ihr Eigengewicht niedergehalten, wobei sich ihre Achslage frei zum Walzband einstellen kann. Unterschiedliche Reibungen zwischen der Antriebs- und Bedienungsseite in den Führungen der oberen Treibrolle und den Pneumatikzylindern können jedoch dazu führen, daß sich die Treibrolle im Betrieb schräg stellt und nicht die vom Band gewünschte Lage einnimmt. Die Folge kann ein Verlaufen des Bandes sein. Auch das Spiel der Lagerung der Treibrollen kann sich nachteilig auf die Führung bzw. auf den Bandlauf auswirken. Erfindungsgemäß wird dies jedoch dadurch vermieden, daß die untere Treibrolle (1) gegenüber der mit der Schwinge (18) verbundenen oberen Treibrolle (15) im Ständer (5) schwenkbeweglich verstellbar gelagert ist, und daß die Lagergehäuse (6, 7) der unteren Treibrolle (1) mit in etwa vertikaler Richtung wirkenden Druckmittelzylindern (11, 12) und Positionsgebern (13, 14) in Verbindung stehen. Bei eingeschalteter Druckregelung ist die Rollenanpreßkraft nich abhängig vom Differenzmaß zwischen Banddicke und Rollenspalt, sondern vom eingestellten Hydraulikdruck. Die Einrichtung ermöglicht auch ein automatisches Nullen des Treibrollenspaltes.

Abstract: A nuclear magnetic resonance method and apparatus for examining a predetermined particular location (55) in a body wherein processed data obtained from four procedures are combined to extract processed data relating to the particular location. Each procedure comprises exciting spins in a region (45) of the body including the location (55) and acquiring and processing data in respect of the excited spins. In a first procedure the excited spins are of the same phase throughout the region (45). In a second procedure the excited spins are of a first phase in a first portion (49) of the region (45) of which portion the predetermined location (55) forms part, and are of the opposite phase in the rest of the region (45). In a third procedure the excited spins are of a first phase in a second portion (53) of the region which intersects the first portion (45) at the predetermined location (55) and are of the opposite phase in the rest of the region (45). In a fourth procedure the excited spins are of a first phase in the first and second portions (49 and 53), excluding the predetermined location (55), and are of the opposite phase in the rest of the region (45). Adding the processed data signals from the first and fourth procedures and subtracting the processed data signals for the second and third procedures gives a resultant signal relating to the predetermined location (55) only.

Abstract: In a quadrature amplitude modulator, two binary, synchronous data signals representing four possible phase states of a carrier signal are sampled and respectively fed into two shift registers comprising part of a finite impulse response lowpass filter. The samples in each corresponding pair of stages in the shift registers are multiplexed at twice the carrier frequency. Each multiplexer output is then added modulo-two to a binary signal at the carrier frequency using exclusive-OR gates. The gate outputs are weighted in a desired fashion and summed and converted to an analog signal which exhibits a preferred spectral shape. This approach enables the quadrature amplitude modulation function to be included within the structure of the finite impulse response lowpass filter. The binary synchronous nature of the input data enables the structure of the filter to be simplified and the number of multiplexers and modulo-two adders to be reduced to a number equal to the number of bits stored from the input sequences. An extension of this basic concept includes higher levels of encoding, specifically the case of sixteen or more possible phase and amplitude states of a carrier signal. The particular method for weighting and summing the multiplexed and modulated signals may utilize digital logic combined with resistors, switched capacitors, or a stored program combined with a digital-to-analog converter, and is suitable for integrated circuit fabrication.

Abstract: A temperature responsive transmitter in which frequency varies linearly with temperature includes two identically biased transistors, T i , T 2  connected in parallel. A capacitor C l , which reflects into the common bases to generate negative resistance in parallel with the capacitor, is connected to the common emitters. A crystal 30 is in parallel with the capacitor and the negative resistance. Oscillations occur if the magnitude of the absolute value of the negative resistance is less than the positive resistive impedance of the capacitor and the inductance of the crystal. The crystal has a large linear temperature coefficient and a resonant frequency which is substantially less than the gain-bandwidth product of the transistors to ensure that the crystal primarily determines the frequency of oscillation. A high-Q tank circuit having an inductor, L, and a capacitor C 2  is connected to the common collectors to increase the collector current flow, which in turn enhances the radiation of the oscillator frequency by the inductor.

Abstract: In the method according to the invention of producing electrochemical gas sensors having at least one measuring electrode consisting of metal sheet and one counterelectrode, optionally an additional reference electrode, and also a gel electrolyte between measuring and counterelectrode, the gel electrolyte material is first subjected to a vacuum treatment for the purpose of degassing, and then to a polymerisation process. Only then is the metal sheet for the measuring and/or counterelectrode applied to the surface of the polymerised gel electrolyte. Because of the precise, uniform and continuous contact between the electrodes and the gel thereby achieved, the sensitivity, the reproducibility and the long-term stability can be substantially improved and the response and decay times of the gas sensors appreciably shortened. The production method can be optimised still further by applying a plastic film to the surface of the gel electrolyte before the polymerisation process. <IMAGE>

Abstract: Die Erfindung betrifft ein Verfahren zum mengengeregelten kontinuierlichen Flüssigkeitsaustausch in Destillationsanlagen und Absorptionskältekreisläufen sowie eine Vorrichtung zur Durchführung des Verfahrens. Bei diesem Verfahren wird einerseits ein in den Hochdruckbereich definiert einzuspeisender Flüssigkeitsmengenstrom an angereicherter Ausgangslösung angehoben, andererseits werden die voneinander getrennten, in der Summe mengengleich aus dem Hochdruckbereich abzuführenden Flüssigkeitsströme des Produktkondensats und der abgereicherten Lösung von einen hohen Druckniveau auf ein niederes Druckniveau übergeführt. Das Verfahren nutzt in einer Lösungsaustauschvorrichtung die mechanische Energie der druckzuentlastenden, auszufördernden Flüssigkeitsströme für die Einspeisung der angereicherten Ausganglösung und benötigt nur noch eine geringfügige äußere Antriebshilfe zur Überwindung der internen Reibungs- und Überströmungsverluste. Die druckzuentlastenden Flüssigkeitsströme werden hierfür vor dem mechanischen Energietransfer bis unter die Sättigungstrmperatur ihres jeweiligen Entspannungsniveaus abgekühlt. Die Vorrichtung arbeitet nach dem Verdrängungsprinzip. Bei Absorptionskältekreisläufen wird sie vorzugsweise mit Kältemitteldampf angetrieben.
