Patent EP-0288826-A1 (EP)
Inventor: NIEMIEC ALBIN JOSEPH
IPC: F04B49/00
Filed: 1988-04-14
Abstract: A hydraulic system comprised of a pump (10), a first valve (15) in the inlet (11) to the pump (10), and a second valve (18) which activates or deactivates a third valve (20) which permits the loading and unloading of the pump discharge. A motor (16) is provided to operate the first valve (15) for opening or closing the pump inlet (11). This motor (16) also actuates the second valve (18) in concert with the operation of the first valve (15) to open or close a vent port to the third valve (20) which opens or closes the passage (19) from the pump discharge to tank, located away from the pump inlet (11). This permits unloading the pump discharge during the restriction (23) of the pump inlet (11) and allows the loading of the pump discharge after the opening of the pump inlet (11). With the pump inlet (11) restricted (23), the system provides a low restrictive passage (23) for circulating the prescribed small volume of flow used to lubricate and cool the pump.

Abstract: A device for sealing a bayonet catch is proposed, in which a locking piece (9) can be pushed into the curve slot (20) of the bayonet nut (1) and, in the pushed-in state, openings (21, 24) are released for a sealing wire (7) to be pulled through. The locking piece (9), which is constructed as an injection moulded part, has a plate (26) by means of which the locking piece (9) is guided in a pocket (27) constructed in the bayonet nut (1). A bolt (19), integrally formed on the locking piece (9), engages through a slot (28), located in the pocket (27), through the wall of the bayonet nut (1) inwards and hence engages in the curve slot (20) of the bayonet catch when the locking piece (9) is pushed in the direction of the connecting socket (3), once the bayonet catch has been engaged. For use, inter alia, as the means of connection for test equipment and counters, or control and regulation devices. <IMAGE>

Abstract: The invention relates to a process for the preparation of a high-temperature superconducting component which comprises a support metal coated with a superconducting ceramic material. It is proposed that the ceramic material be applied to the support metal by enamelling or by a combination of enamelling and glass ceramic technology. The high-temperature superconducting properties of the enamel layer (2) are produced, for example, by glass-ceramic heat treatment. The components produced in this process can be connected in a conducting manner and are suitable for the construction of a high-temperature superconducting connecting line. <IMAGE>

Abstract: Low-noise oscillator comprising a non-linear element consisting of a superconducting material. 
<??>In an illustrative embodiment, it comprises:
 - a resonator consisting of a coil (L2), a capacitor (C1), and a sustaining coil (L1), which are made from a superconducting material and are kept at a low temperature, below the critical temperature;
 - a linear amplifier (2) which always operates within its linear zone;
 - a load (R2). 
<??>The amplitude of the oscillation levels off when the amplitude of the oscillation has reached a threshold value such that the superconducting material making up the coil (L2) of the resonator gradually becomes resistive under the action of the magnetic field created by this same coil. The coil (L2) then dissipates part of the energy injected into the resonator. Since the high-frequency noise from the oscillator is determined essentially by the low-frequency noise from its non-linear element, the use of a low-temperature superconducting material to make up the non-linear element enables an oscillator with very low noise to be obtained. 
<??>Application in particular to voltage-controlled oscillators.

Abstract: Un dispositif d'augmentation d'une ligne adaptative à canaux I-Q possède des filtres passe-bande (20, 78, 86) avec des bandes passantes qui peuvent être élargies jusqu'à des valeurs bien supérieures à celles de la bande en cours de traitement par le dispositif d'augmentation de la ligne adaptative. Ceci permet d'éliminer le besoin de filtrer l'une des bandes latérales comme cela est nécessaire dans des dispositifs d'augmentation de lignes adaptatives à un seul canal, où les bandes latérales de somme et de différence sont générées par conversion incrémentielle. La limitation de la bande s'effectue avec des filtres passe-bas (38, 40, 54, 70) et l'oscillateur local (22) peut être rendu variable de sorte que n'importe quelle partie de la bande qui passe par les filtres passe-bande peut être traitée par un seul dispositif d'augmentation de ligne adaptative à canaux I-Q. Ce type de dispositif d'augmentation de lignes adaptatives à canaux I-Q peut traiter une bande quelconque parmi un grand nombre de bandes possible sans utiliser des filtres passe-bande syntonisables, ou sans utiliser des groupes de dispositifs d'augmentation de lignes adaptives qui ont été préréglés sur des sous-bandes adjacentes.
