Abstract: Un laser à gaz (10) sous haute pression à pompage par micro-ondes, en particulier un laser excimer, comprend un résonateur optique (26), un volume de gaz de résonance (52) agencé dans le résonateur et s'étendant le long d'un axe optique (30) de celui-ci et une structure de couplage à micro-ondes (16) qui renferme le volume de gaz de résonance (52) et qui est reliée à un générateur de micro-ondes (12). Afin d'améliorer un tel laser à gaz de façon à empêcher un effondrement de ses parois, une zone centrale (62) ayant une intensité de champ électrique (60) supérieure à une valeur de seuil requise pour une décharge de gaz à haute pression est agencée à l'intérieur du volume de gaz de résonance transversalement à l'axe optique (30).

Abstract: In electrical devices connected to high-voltage, especially machine and mains transformers, components (3, 5) for the electrical and mechanical connection of the end of a feedthrough conductor bolt (3) to a connecting conductor (12) carrying high-voltage are often arranged in a chalice-shaped screen (4). According to the invention, in order to damp high-frequency switching oscillations a low-inductance fixed resistor (9), forming the end of the connecting conductor (12), is spatially and electrically arranged between the chalice-shaped screen (4) and a chalice-shaped screening pot (10) similar to said screen, an iron-free choke winding (8) carrying the load current being provided electrically in parallel with, and spatially coaxially with respect to, the fixed resistor (9), which choke winding (8) grips the screening pot (10) with its one end and the screen (4) with its other end. The combination of a high-voltage feedthrough (2) with a damping element for oscillations in the MHz range is especially expedient in cases in which a 400 kV transformer is directly coupled to an SF6 switching device. <IMAGE>

Abstract: A device for the collection of eggs comprises a number of egg conveyor belts lying above one another, an egg discharge belt (10) and a device disposed between the egg conveyor belts and the egg discharge belt for transferring eggs from the egg conveyor belts to the egg discharge belt. The transfer device comprises an essentially vertically arranged endless egg conveyor (11) which at the top and bottom side is guided over reversing mechanisms, the egg conveyor has a first part which can move up past the ends of egg conveyor belts, and a second part which can move down past the egg discharge belt (10). The egg conveyor is provided with egg accommodation elements (14) disposed abutting one after the other in the lengthwise direction of the egg conveyor and essentially U-shaped, viewed in the transverse direction of the egg conveyor, and open towards the outside, and extending over the width of the egg conveyor. The egg accommodation elements (14) are divided by means of separating elements (18) into a number of individual adjacent compartments (19), the separating elements (18) lying one after the other in the lengthwise direction of the egg conveyor (11), and the width of the compartments (19) being such that only one egg fits into each compartment (19). The egg conveyor (11) is arranged in such a way that the eggs fed in by a particular egg conveyor belt can be accommodated in only one specific row of compartments (19) lying one after the other in the lengthwise direction of the egg conveyor (11).

Abstract: A method of forming a conducted panel for use in a refrigerated vehicle or container is described. The method comprises assembling two layers of insulative material (2, 14) which are spaced by a number of dividers (8a, 8b), preferably also formed from insulative material, with adhesive between the parts. An air bag (10) is placed between each adjacent pair of dividers and its interior is vented to the atmosphere. The assembly is placed on a vacuum table (6) covered by a vacuum blanket (18) and a vacuum is applied below the blanket to force the parts into good contact. The pressure differential causes the air bag to expand, thereby preventing collapse of any of the parts. The air bag may also act as the line for the duct or ducts so formed.

Abstract: A quick connect/disconnect coupling for hydraulic or pneumatic conduits has a male half (4) and a female half (2) with respective fluid bores (5,3) therethrough. Split ring segments (7) are arranged in a ring within the female coupling half (2) and are movable therein. The ring segments are biased towards the centreline (50) of the coupling by an elastic O-ring (9). When the coupling halves are engaged, the ring segments are positioned between a radially extending shoulder (6) on the male coupling half and a radially extending shoulder (21) on the female coupling half. In the engaged and locked position of the coupling halves, the ring segments (7) in blocking relation with the shoulders (6,12) hold the coupling halves together. The ring segments are in abutting relation with adjacent ring segments on either side when the coupling halves are in the engaged in locked position. The male coupling half includes a tubular releasing member (10) slidable mounted thereon. When the releasing member (10) is moved in the direction of the female coupling half a ramped face (18) of the releasing member moves the ring segments radially outwardly above the shoulder (6) on the male coupling half and enables the coupling halves to be disconnected.

IPC: B66C23/90
Filed: 1989-07-04
Abstract: The device is intended in particular for cranes provided with hydraulic load control systems piloted by a pressure signal proportional to the overturning moment generated by the load, which produce control signals that block any movement of the crane likely to increase the load; use is made of a three-position bleed-off valve (12) which, in a non-stable position assumed momentarily as the spool shifts back and forth between two stable positions, brings about a reduction in the pilot pressure directed into the control system (10) so as to avoid lock-up of the crane that can occur in certain maximum load conditions. A valve (12) of this type also achieves a significant reduction of the hysteresis that traditionally delays the return of such systems (10) to the passive state.

Abstract: Des modulateurs (2B, 2G, 2R) à cristaux liquides à pertes réduites utiles pour colorer et façonner des faisceaux de lumière (IB) permettent d'obtenir une variation continue de la couleur et de l'intensité de sortie par dispersion commandée. Les modulateurs (2B, 2G, 2R) à cristaux liquides comprennent des feuilles adressables d'occlusions de cristaux liquides ayant la grandeur de la longueur d'onde de la lumière dans une matrice transparente (21). Les modulateurs (2B, 2G, 2R) utilisent des cristaux liquides nématiques à anisotropie diélectrique et servent à modifier et à colorer des faiceaux de sortie (OB), à des fins de transmission de données colorées ou vidéo. Les images obtenues peuvent se modifier dans le temps, comme l'exige la télévision en couleurs, par exemple. Ces modulateurs sont utilisés dans des projecteurs en couleurs de données et vidéo, pour l'impression en couleurs, et pour l'éclairage coloré d'une scène. La transmission à pertes réduites qui caractérise ces modulateurs (2B, 2G, 2R) permet d'obtenir des images brillantes qui peuvent être visionnées même sous un fort éclairage ambiant.

Abstract: Le gain initial d'un égaliseur automatique est fixé à une valeur prédéterminée. Le gain le plus approprié de l'égaliseur automatique est déterminé ensuite lorsqu'un signal d'entraînement est reçu par l'égaliseur automatique. Un signal de réplique d'écho produit par un annulateur d'écho est multiplié par la valeur obtenue en divisant le gain le plus approprié par le gain initial. Par conséquent, le signal de réplique d'écho est corrigé pour annuler le signal d'écho inclus dans le signal de sortie de l'égaliseur automatique. La cadence d'échantillonnage du convertisseur A-N utilisé dans l'émetteur-récepteur est décalée d'une valeur déterminée par rapport à la cadence de la ligne de transmission pendant une étape initiale d'entraînement. Par la suite, la cadence d'échantillonnage du convertisseur A-N est maintenue à une valeur proche de celle de la ligne de transmission.
