Abstract: Bei der Herstellung von Spreng- oder Zündschnüren, die mit Kunststoff ummantelt sind, wird eine Rohschnur (18), die Explosivstoff enthält, durch den Kern einer Extruderdüse (17) geleitet und dabei mit Kunststoff umspritzt. Meßfühler (23,24) in der Zuführleitung (13) für den Kunststoff überwachen die Temperatur und/oder den Druck in der Zuführleitung. Wenn zulässige Grenzwerte überschritten werden, werden das Mundstück (16) und die Pinole (15) der Vorrichtung von dem Block (11) in entgegengesetzte Richtungen auseinandergefahren. Die in Längsrichtung geteilte Pinole (15) wird durch Hilfsantriebe (28) von dem Strang (18) getrennt. Durch einen weiteren Hilfsantrieb (31) wird ein Stopfen (32) aus der Wand des Zuführkanals (13) herausgezogen, um eine Druckentlastung vorzunehmen. Außerdem wird die Rohschnur (18) durch Rücklaufvorrichtung (33,34) aus dem Gefahrenbereich herausgezogen. Ferner erfolgt im Auslösefall der Schutzvorrichtung eine zusätzliche Kühlung.

Abstract: Radiation treatment planning method and apparatus. A differential scatter-air ratio calculation procedure is utilized to calculate scatter contribution which when combined with primary radiation yields dose. The lenghty polar coordinate integration of the prior art is replaced with a rectangular coordinate integration which to an extent can be performed outside an integration loop. Beam characeristics are entered into a one dimensional matrix BWP. A second matrix RSAR includes the differential scatter-air ratio for incremental regions within the body at a certain depth and radial distance from a scatter calculation point. During a rectangular coordinate integration, a twc dimensional coordinate within a body plane determines an offset into both the one dimensional beam characteristic matrix BWP and the differential scatter-air ratio matrix RSAR. The values are multipled to produce a scatter contribution from the incremental region.

Abstract: In a transmission system of signals including amplitude-modulated television signals, a pilot signal of a specific amplitude is supplied by a signal generator (102) at a first place (103) in the transmission system, and extracted at a second place (105) in the transmission system, the pilot signal having been subjected to a cross modulation due to nonlinearity of the transmission system (104) from the first place to the second place. A rectifier included in a distortion detector (106) obtains an envelope of the cross molulated pilot signal. In consequence, out of the envelope, the fundamental wave component or a higher harmonic component of the horizontal scanning frequency of the transmitted television signal is extracted by using a filter of an extremely narrow band. By detecting the increase in the level of this removed signal, increase of distortion due to excess level of the transmission signal or trouble of any device in the transmission system is detected.

The second electrode (36) terminates short of both ends (24, 26) of the winding. A conductive tab (44) electrically connects the second electrode (36) with a tab (42) extending beyond a winding end and is insulated at the location where it passes that winding end. A conductive coating covers each of the winding ends (24, 26) so that contact with the first and third electrodes (34, 38) is through respective ends of the winding while contact with the second electrode (36) is through the conductive tab (44). A method of winding such a capacitor is also disclosed.

Abstract: A direct frequency modulation crystal-controlled oscillator circuit is provided having a configuration which minimizes the number of parts required for modulation while maintaining a linear relationship between the incoming modulation voltage and the outputted frequency. The circuit includes a tuning diode (12) in a parallel arrangement with a tank circuit (22) connected to the collector of a transistor (20). In the preferred embodiment, the tank circuit includes only an inductor (24). The crystal (26) of the circuit operates in the anti-resonant mode and its impedance is much greater than that of the tank circuit (22). Direct frequency modulation results from the frequency change of the crystal (26) in responding to a phase change caused by the modulation voltage applied to the tuning diode (12), which subsequently results in a change in the phase of a transistor collector voltage. The desired linear relationship is achieved over a frequency range by prop er selection of the tuning diode (12), wherein the I non-linearity that exists between voltage and capacitance associated with the tuning diode is compensated for by the offsetting non-linearity that exists  between capacitance and frequency associated with the tank circuit (22).

Abstract: An improved leaf spring clamp is provided, particularly for use with composite material leaf springs, to securely fix the position of the leaf spring relative to a wheel axle or other suspension system member, such as in the suspension system of a motor vehicle. The leaf spring clamp comprises a rigid clamp member (30), a resilient wedge insert (60,70), and a rigid clamp plate (40). The clamp member (30) provides a base wall (31) and substantially parallel side walls (32a,32b) extending from the base wall (31) to form a channel adapted to receive the wedge insert (60, 70). The inner surface of at least one side wall of the clamp member is formed with a channel-widening concavity (34a, 34b), preferably at the longitudinal midpoint of the channel. The wedge insert (60, 70) has a base wall (62) and substantially parallel side walls (64a, 64b) extending from the base wall to a top wall and forms an inner channel adapted to laterally jacket the leaf spring. The outer surface of the wedge insert substantially fills the clamp member channel and provides a convexity (66a, 66b) adapted to register with the channel widening concavity (34a, 34b) of the clamp member (30). The clamp plate (40) attaches to the clamp member (30) to clamp the leaf spring between them under a pre-load. The clamp plate (40) and the clamp member (30) together comprise tab-and-slot means (47a, 47b, 37a, 37b) such that they can accurately and easily be attached to each other in position to yield a preselected degree of pre-load.

Abstract: For separating gas mixtures, in particular air, using molecular sieves, a gas compressor (1) is frictionally coupled to an expansion turbine (9) which is run by the pressure medium leaving the molecular sieve (5) and heated by a heat exchanger (8), so that part of the drive energy for the compressor (1) can be saved. For desorbing the oxygen from the oxygen-retaining molecular sieve (5), the latter is heated, the exit gases from a combustion carried out in the heat exchanger (8) being utilised for this purpose. To heat the oxygen- retaining molecular sieve (5), a gas stream is first circulated by a fan (30) via the heat exchanger (27), whereupon, after the required desorption temperature for the oxygen-retaining molecular sieve (5) has been reached, pure oxygen is taken off and can be stored or discharged, for example as compressed oxygen after compression by an oxygen compressor (41). <IMAGE>

Filed: 1986-01-21
Abstract: Une pompe ou moteur rotatif à ailettes oscillantes comprend un cylindre (21) dans lequel sont tourillonnés deux rotors co-axiaux (34, 35). Chaque rotor (34, 35) définit une paire d'ailettes (36, 37, 38, 39) sectorielles espacées, les ailettes d'un rotor étant juxtaposées alternativement aux ailettes de l'autre rotor. Un arbre générateur (50) tourillonné dans le cylindre comprend un arbre creux ou un manchon qui entraîne les arbres coaxiaux (40, 46) du rotor. Des orifices d'admission et des orifices d'évacuation ou d'échappement sont formés dans les cylindres pour recevoir et évacuer du fluide sous pression. Des organes opérationnels de couplage font osciller les rotors l'un par rapport à l'autre à mesure que les rotors tournent par rapport au cylindre. Une goupille d'entraînement (60) traverse les arbres du rotor et l'arbre creux de l'arbre générateur. Une fente allongée (61) est formée dans l'arbre creux (56) pour permettre le mouvement alternatif axial de la goupille lorsque l'arbre générateur tourne. Des fentes hélicoïdales (62, 63) sont définies dans chaque arbre coaxial des rotors, une fente hélicoïdale étant courbée vers la gauche et l'autre vers la droite. Des rouleaux à cames (65) sur des extrémités saillantes de la goupille d'entraînement se déplacent dans une piste de guidage (68) définie par des surfaces (71, 72) de la came sur des tambours annulaires opposés (69, 70) montés dans le cylindre. La rotation relative entre le cylindre et le rotor provoque le mouvement alternatif axial de la goupille et l'oscillation rotative entre les ailettes des rotors pendant que tout le rotor tourne par rapport au cylindre.
