Patent EP-0203729-A1 (EP)
Inventor: PRICE ANTHONY GEORGE
IPC: B60T17/22
Filed: 1986-04-29
Abstract: The pressure plates (1, 2) of a self-energising disc of the spreading type are moved angularly in opposite directions to initiate application of the brake by means of a hydraulic actuator (3) of which the axis is tangential to the axis of the brake. The actuator (3) comprises a pair of opposed pistons (8, 9) working in a bore (7) in a cylinder (6) with a compression spring (12) urging the pistons relatively away from each other. A hold-back device (14) is provided to maintain the effective length of the actuator at a predetermined minimum to facilitate installation of the actuator (3) in the brake. The hold back device (14) may comprise a one-piece plastics moulding surrounded by the spring (12) and having a releasable engageable with both pistons (8, 9), or it may comprise a piston-engagement member (31) of resilient material incorporating a claw-like formation (36) and which is radially arranged to embrace complementary beads or ribs (37) at the adjacent ends of the two pistons.

Abstract: A video optimized, low-cost modulator-demodulator is provided. Each modulated state or symbol (amplitude, phase, frequency or a combination thereof) has a one-to-one correspondence with a particular pixel value of brightness. For a black and white picture, adjacent shades of gray for the pixels are assigned to adjacent amplitude, phase or frequency values (in ROM 38) so that any error in transmission results in a pixel having its shade changed only slightly. A multiple amplitude, two-phase modulation method is preferably used. The black and white values are assigned to the highest amplitude level at opposite phases. As the pixel value becomes less black or white and more gray, it is assigned lower and lower amplitude levels with its phase being determined by whether it is closer to black or to white.

Abstract: The present invention relates to a process for the generation of inert gas, particularly for injecting into an oil well to assist in the recovery of crude oil. 
     According to the invention there is provided a process for recovering nitrogen at supra-atmospheric pressure from a nitrogen-containing gas stream comprising:-
     (a) compressing the gas stream to supra-atmospheric pressure;   (b) passing the compressed stream through a gas permeable membrane which exhibits enhanced permeability towards impurities in the nitrogen stream than towards nitrogen itself whereby to separate at least some of the nitrogen in the stream from the impurities therein, such that the permeate stream is substantially above atmospheric pressure;   (c) increasing the temperature of the separated stream of impurities from step (b);   (d) expanding the hot impurities stream to produce work; and optionally   (e) utilising the work produced in step (d) in the process.   
     Preferably the nitrogen-containing gas stream is air, and the permeate oxygen-rich stream is fired with natural gas to increase the amount of work recovered therefrom on expansion.

Abstract: L'invention concerne un procédé de fabrication de circuits intégrés. Pour réaliser à faible prix de revient des circuits de technologie CMOS incorporant des transistors bipolaires, on réalise une succession d'étapes avec seulement neuf masques successifs aboutissant notamment à un transistor bipolaire NPN latéral dans un caisson P sur substrat N. Les contacts de source et drain (68) sont en siliciure métallique, de même que le contact de base (72). Les contacts d'émetteur et collecteur (34, 36) sont en silicium polycristallin recouvert de siliciure. Le transistor N est auto-aligné avec une faible résistance d'accès et une faible profondeur de jonction. L'implantation ionique source et drain du TMOSP d'une part et de base de bipolaire d'autre part est commune. De plus la résistance d'accès au transistor de type P et le recouvrement de grille sur sources et drains de ce transistor sont minimisés tout en laissant une grande latitude de choix sur le dopage de la base du transistor bipolaire.

Abstract: The sensor is for measuring the oxygen content of a gas and consists of at least one piece of cerium oxide (4, 5) and means for measuring the conductivity or resistance of this piece. The cerium oxide is of normal commercial purity and includes at least one cation of an element with an oxidation number greater than 4 and soluble in the cerium oxide. The concentration of this cation is sufficient for the conduction of the layer to be mainly electronic in character and to be a function of the partial pressure of oxygen. This concentration does not exceed a certain threshold, beyond which the electron concentration involved in the conduction is equal or proportional to that of the said cations and is independent of the oxygen pressure. Application mainly in detecting the partial pressure of oxygen in the exhaust gases from car engines. <IMAGE>

Abstract: Procédé pour la mesure en continu de la porosité d'une bande (1) de matière poreuse passant à travers une tête de mesure (2). Une pression négative produite par un ventilateur extracteur est constamment mesurée par un capteur (7) et maintenue à une valeur aussi constante que possible par une installation de réglage qui commande le ventilateur extracteur (5). Sur la base de la quantité du flux d'air mesuré et d'autres paramètres de l'air et de la bande (1) mesurés par des capteurs (9, 10 et 14, 15) le micro-ordinateur (8) calcule en permanence la porosité de la bande (1) passant sur la tête de mesure (2). Toute déviation de réglage pouvant se produire malgré le réglage de la pression négative présente dans la chambre de mesure (4) est compensée par la prise en compte de la variation temporelle de la pression négative lors du calcul de la porosité.

Title: Broadbanded  microstrip antenna having series-broadbanding capacitance integral with feedline connection
Inventor: PASCHEN DEAN A
IPC: H01Q9/04
Filed: 1987-05-14
Abstract: The feedline connection (208, 250) to a microstrip antenna patch (100) is desinged to integrally include a predetermined capacitance (260, 270) for broadbanded operation. RLC parameters of a parallel circuit model for a specific radiator for a given feedpoint location are measured or otherwise determined. A series LC feed network (250, 260, 270) is then employed and predetermined series LC parameters are chosen so as to optimize the desired bandwidth for the resulting two-stage band pass filter network. The resulting broadbanded microstrip antenna system network may provide an operating bandwidth on the order of 30% (with less than 2:1 VSWR).

Abstract: A gas stream comprising hydrogen, nitrogen, methane and argon is subjected to the following steps:
     (i) separation of methane and most of the nitrogen in the gas stream in a pressure swing adsorption system 2 using molecular sieve or activated carbon material.   (ii) separation of most of the hydrogen in a membrane separator 5. The separated hydrogen may be used as purge gas for regeneration of the pressure swing adsorption system 2 of step (i).   (iii) separation of the nitrogen and residual hydrogen in a cryogenic distillation unit 8 to obtain essentially pure liquid argon product.   
     In a Step (ii) above may be eliminated and separation of hydrogen is then accomplished by cryogenic separation in combination with step (iii). In a further alternative, separation of most of the hydrogen is accomplished by metal hydride adsorption in place of membrane separation. The present process is applicable to the recovery of argon from ammonia synthesis plant purge gas stream, which is pre-heated typically in a membrane to reduce its hydrogen content. The pre-treatment may also include an ammonia removal step.
