Patent EP-0043783-A1 (EP)
Inventor: HUISSOUD BERNARD ERNEST
IPC: G09F7/10
Filed: 1981-06-24
Abstract: Tamper-prove device for displaying the reservation, for a given moment, of the exercising of a right to use an item, presented in the form of a board of lines and columns (11) corresponding, respectively, to the item and to the moment of said exercising, and defining compartments (12) in which personalised tokens (33) are deposited. Each column (11) has the form of a stack of transparent windows (12, 23) behind which cavities (15) retain, in a visible manner and without the possibility of removal, the reservation tokens (33) before the expiry of the right. At this moment, a slide (13) actuated by a cam (30) places openings (26) in correspondence with the cavities (15) and the tokens (33) are removed by gravity in order to be recovered and, if appropriate, controlled. The device has a particularly advantageous use in the irrevocable reservation of playing areas, particularly tennis courts, a field in which fraudulent reservations are frequent. <IMAGE>

Title: Antenne en castree de couverture hemisperique de polarisation circulaire
Inventor: FINKEN KENNETH R
IPC: H01Q13/10
Filed: 1981-05-12
Abstract: Conception d'antenne capable d'effectuer une couverture hemispherique uniforme ou conique sur des signaux polarises de maniere circulaire a partir d'une structure de radiation tres fine ou encastree. A cet effet, l'antenne possede une rangee d'elements de radiation (N = trois ou plus) (11-14) alimentes en phase tournante (c-a-d 360 /N de difference de phase entre les elements) pour effectuer une polarisation circulaire. Ces elements peuvent etre des bras de reactance courts charges asymetriquement par le haut, des fentes desequilibrees, des bras de reactance du type "L", des fentes de forme "U" ou autre type d'elements desequilibres qui assurent une couverture libre nulle dans un hemisphere. La forme de ces elements et leur position dans la rangee commandent la forme desiree de la configuration de l'antenne. Les elements de l'antenne sont montes sur une premiere plaque de circuits imprimes (15) qui est espacee a l'aide d'un dispositif d'espacement dielectrique (20) d'un reseau de couplage/mise en phase d'impedance telle que des reseaux hybrides a 90 et 180 formes sur une seconde plaque a circuits imprimes (21). Le rapport signal zenith (ou nadir)-signal d'horizon est commande par la position des cables d'alimentation verticaux qui s'etendent depuis la plaque de circuit hybride au travers du dispositif d'espacement vers les elements de radiation, et le degre de desequilibre des elements de radiation. L'assemblage des composants de chaque structure d'antenne s'effectue en montant des vis qui s'etendent depuis une plaque a circuits imprimes au travers du dispositif d'espacement dielectrique mince vers l'autre plaque. La structure mince resultante permet de s'adapter a des surfaces courbes telles que le fuselage d'un avion; si on le desire, cependant, l'antenne peut etre montee dans un evidement sous la surface de l'avion pour obtenir ainsi un dispositif de montage completement encastre.

Abstract: A clamping device for thin flexible printing plates has a tensioning rail at the trailing wall of a wide longitudinal groove in the plate cylinder. The tensioning unit is mounted for axial and peripheral adjustment on a support of "L" cross-section having a first leg seated with respect to the bottom of the groove and a second leg presenting an upstanding reference surface interposed between the tensioning rail and the trailing wall of the groove. A set of tensioning springs recessed in the tensioning rail bear against the reference surface and apply peripheral tension to the plate. A spring detent latches the tensioning rail temporarily against the reference surface, overcoming the tensioning springs while the trailing edge of the plate is being gripped. The spring detent is mounted upon and movable with the support. Screws having a plurality of selectable holes anchor the support in a series of peripheral positions for accommodation of plates of different length. A plurality of jack screws threaded into the tensioning rail have tips which bear against the reference surface on the support for removing slack from the plate and for tensioning of the plate about the surface of the cylinder.

Abstract: A speech recognition device can record or recognize spoken instruction phrases reliably even when engine noise increases high within the passenger compartment. When the engine begins to operate, the gain of an amplifier of a speech input section (6) or the threshold level of a voice detector (7) is so switched as to reduce the sensitivity to spoken instructions. As a result, the driver must necessarily utter a spoken instruction in a louder voice and thus the proportion of noise level to spoken instruction signal level is reduced. The system comprises engine operation detecting means (15, 16, 17, 5), an analog switch, two amplifiers or two multipliers, etc. in addition to the conventional speech recognizer.

Abstract: A termination device (48') for absorbing RF energy waves in the termination chamber (34) of a travelling wave tube. The termination device is formed by modifying two wedge shaped termination devices of the prior art. Specifically, two prior art single wedge termination devices are sliced in half to produce two wedges each one half the thickness of the single wedge device. The two halves are positioned with their newly formed surface, formed by the slicing, in opposed facing contact The new double wedge (48') thus has the same thickness as the prior single wedge and is readily accommodated within the termination chamber. The double wedge termination device greatly reduces small signal gain variations across the operating frequency band of the traveling wave tube.

Abstract: A thyristor having a P +  emitter region, an N- base region, a P base region, and an N +  emitter region includes an anode and a cathode ohmically connected to the P +  emitter and N +  emitter regions, respectively. A further P +  region adjoins the N +  emitter region and is ohmically connected to the cathode. Metal-Oxide-Semiconductor ("MOS") turn-off structure having a control electrode is included in the thyristor for transporting holes from the P base region to the further P +  region, and thence to the cathode when the control electrode is biased with a voltage below a threshold value in magnitude (e.g., zero volts). Such biasing creates an impediment to turn-on of the thyristor. When the control electrode is biased with a voltage above a threshold value in magnitude, the MOS structure no longer transports holes from the P base region to the further P +  region, thereby removing the foregoing impediment to turn-on of the thyristor.
