Title: Ultraleger motorise avec une aile rigide tournant librement
IPC: B64C31/028
Filed: 1985-03-08
Granted: 1990-03-07
Abstract: Un ultraléger motorisé (10) à construction minimale légère comporte une aile rigide (12) à laquelle est suspendue une cage (15) par le biais d'un montage principal d'articulation (13). La rotation de l'aile (12) sans intervention du pilote et induite par les rafales de vent positives ou négatives frappant l'aile (12) provoque la variation de l'angle d'inclinaison entre l'aile et la cage suspendue (13) grâce à l'articulation, si bien que l'aile présente un angle d'attaque relativement constant à un vent relatif permettant à l'ultraléger motorisé de ne pas décrocher pendant le vol. Le vrillage et/ou ledit dièdre de l'aile (12) est maintenu par un premier et un second ensembles de câbles tendus (103) ou haubans de soutien au sol (105) reliant les bords d'attaque et de fuite de l'aile à un pylône (100) saillant vers le haut à partir de l'aile, et par un premier et un second ensembles d'haubans porteurs (122) reliant l'aile à la cage suspendue. Chaque premier et second ensembles d'haubans porteurs est un montage de repartition de la contrainte comportant une paire de tubes (110) connectés respectivement par leurs extrêmités supérieures aux bords d'attaque et de fuite de l'aile et par leurs extrêmités inférieures à une plaque (120) suspendue entre l'aile et la cage suspendue. Une paire de câbles tendus dans chaque ensemble relie la plaque à la cage suspendue (15). Le point de fixation des câbles sur la plaque crée un point de pivot (125) situé de manière colinéaire avec l'axe de l'articulation (32). Les tubes (110) peuvent tourner librement autour du point de pivot (125) pendant la co-rotation de l'aile (12), tout en maintenant un vrillage de l'aile et un dièdre correct, ainsi qu'une tension transmettant une contrainte de flexion agissant sur l'aile (12) à la cage suspendue (15).

Abstract: Radiomètre (100) qui utilise le diagramme d'interférence d'un interféromètre (110) pour balayer une scène afin de produire un enregistrement temporel à partir duquel une distribution de hautes fréquences ou d'autres rayonnements à haute résolution de la scène peut être reconstruite. Un filtre adapté (120), ou d'autres dispositifs, transforme l'enregistrement temporel selon une fonction d'une signature du balayage déterminable relativement au diagramme d'interférence. Dans de nombreux modes de réalisation, la fonction de transfert de modulation (123) d'un filtre adapté inclus est le conjugué complexe de l'intégrale de Fourier de la signature qui serait produite par un émetteur à points constants balayé par les lobes du diagramme d'interférence de l'interféromètre. Des reconstructions bidimensionnelles peuvent être obtenues par des balayages. Alternativement, un balayage de fréquence ou une autre technique de balayage peuvent fournir une résolution orthogonale par rapport au mouvement de balayage du diagramme d'interférence. Des distributions focalisées de scènes multiples et des mouvements complexes de balayage sont fournis par des sélections appropriées d'une ou plusieurs signatures pour traiter un enregistrement temporel donné.

Granted: 1990-07-25
Abstract: Dans une machine de moulage par injection dont le mécanisme d'injection (200) est entraîné par un servomoteur pour exécuter l'opération d'injection, un dispositif de commande de la pression d'injection empêche le surmenage du mécanisme d'injection. Le dispositif de commande de l'injection comprend un circuit (2) de limitation du couple qui limite la valeur d'une instruction (e) de couple à la valeur d'une instruction (g) de limitation de couple donnée par une unité de commande numérique. L'instruction (e) de couple est générée par un servo-circuit qui fonctionne dans la direction d'injection dudit mécamisme d'injection. Le circuit (2) de limitation de couple ne limite cependant pas le couple pour ce qui est de l'instruction d'entraînement dans la direction opposée à la direction d'injection. Il est donc possible de ralentir rapidement le servomoteur qui entraîne le mécanisme d'injection pour empêcher celui-ci de se surmener.

Abstract: PCT No. PCT/BR86/00016 Sec. 371 Date May 8, 1987 Sec. 102(e) Date May 8, 1987 PCT Filed Aug. 21, 1986 PCT Pub. No. WO87/01293 PCT Pub. Date Mar. 12, 1987.The present invention relates to a tracheostomy cannula with a small balloon or cuff (2) positioned posteriorly (or cranially) to the tube (1) which is consequently shorter. This tube (1) has a collar (5) that encircles the tube on its proximal portion and prevents air leakage through the stoma. The "cuff" (2) also may communicate with the environmental air by means of conduits (6) that may be flexible. Since the component structures of a cannula so formed progress only a small distance caudally into the trachea, some complications, if not completely avoided, are better guarded against. Thus, there is when using the present invention less stimulus to a coughing reflex. Moreover, its cleaning and that of the trachea are simpler, and a tracheo-innominate fistula will rarely occur.

Granted: 1999-12-15
Abstract: A process is disclosed for improving the isolation between semi-oxide insulated devices, formed on mesa structures. In the fabrication of such devices, a silicon substrate is provided. Patterned regions of one type of conductivity are formed in a major surface of the substrate and an epitaxial layer of silicon is formed on the substrate over the major surface. A patterned mask layer is formed on the epitaxial layer and is etched to expose portions of the epitaxial layer. The exposed portions of the epitaxial layer are removed to form the mesa structures, which overlie the doped patterned regions. Regions of opposite conductivity, called channel stops, are then formed in the substrate between the patterned regions. After filling in the areas between the mesa structures with a field oxide, the devices (bipolar or MOS transistors) are formed on the mesa structures. The process of the invention utilizes as a mask structure a mask having a combination of properties (composition and thickness) related to the subsequent processing. The mask permits use of an anisotropic etchant to define the mesa structures and to undercut the mask. An oxide layer is formed on the side walls of the mesa structures and on those portions of the substrate exposed during the mesa-defining step. Those portions of the oxide layer underlying openings in the mask structure are removed to expose portions of the substrate, which encompass regions between the doped patterned regions. The channel stop dopant is introduced into the regions between the patterned regions.

Title: Cordless telephone
IPC: H04M1/72502
Filed: 1988-01-16
Granted: 1992-11-04
Abstract: If, in a handset of a cordless telephone, the battery (15) housed in the handset casing goes flat, a voltage monitoring circuit (14) connected to the battery detects that the battery voltage has fallen below the pre-defined minimum level and activates a warning signal via a first microprocessor circuit (13). If the flat battery is replaced with a charged or recharged spare battery (29) while a call is in progress, the transmission power of the handset (10) fails. This failure is detected by a field strength evaluator (25) of the base station (20) and reported to a second microprocessor circuit (23) of the base station. This prevents the telecommunications component (26) of the base station from interrupting the telecommunications link with the user. After a pre-defined time, the second microprocessor circuit clears down the radio link between the base station and the handset and, once the battery has been changed, a new radio link is set up to the handset on a free radio channel. <IMAGE>

Abstract: Apparatus for denitrifying power station excess gases (crude gas) which come from a flue gas desulphurisation unit and are heated to the requisite catalyst temperature before the injection of ammonia by heat exchange with the denitrified gases (pure gas) and by supplying additional heat. Known denitrification devices fitted with regenerative heat exchangers operate with large gap and leakage losses, which leads to restrictions in the achievable degree of denitrification and hence the efficiency. Moreover, known denitrification devices have a large space requirement, which makes expensive heat insulation measures necessary due to the free surfaces, in order to prevent a deterioration in efficiency due to heat losses. It is proposed to use, for the heat exchange between crude gas and pure gas, a plate heat exchanger (4) which operates in cross-counterflow, the additional heat being supplied and the ammonia being injected (14) to the outlet duct (9) of the plate heat exchanger. At the end of the outlet duct (9) is arranged a deflection hood (16), with the catalysts (9a, 9b) being arranged between its outlet and the re-entry of the denitrified gases into the plate heat exchanger (4). <IMAGE>
