Patent EP-0197717-A1 (EP)
Inventor: WELTMER WILLIAM R
IPC: B01D53/34
Filed: 1986-03-26
Abstract: An inert gas stream containing parts per million levels of impurities such as O2, CO, CO<sub>2</sub>, H<sub>2</sub>, H<sub>2</sub>0, is purified by passing the same sequentially through a first bed and second bed of material. In the first bed, carbon monoxide and hydrogen are both reacted with oxygen to form CO<sub>2</sub> and H<sub>2</sub>0. The latter is retained in this first bed while the reaction products and the inert gas stream are supplied to a second of material which is comprised of a getter. In this bed, oxygen reacts with the getter material and carbon dioxide is adsorbed therein so that the inert gas stream leaving the second bed is substantially free of such impurities. The first and second beds of material operate at temperatures up to about 38°C and these materials may be regenerated by heating the same to approximately 200°C and purging such beds with a purge gas flow.

Abstract: An electrochemical system for determining the concentration of a bacteria or other enzymatic agents in a liquid sample (14). The system includes mounting means (20) for mounting an electrode assembly (16), and drive means for rotating the electrode assembly. The electrode assembly comprises a shaft (22) having a longitudinal axis and a iongi- tudinally extending interior passage (40), an electrode (24) mounted at the lower end of the shaft, and sparging means (26) extending laterally from the lower end of the shaft. The sparging means is in communication with passage (40) through openings (50). The electrode and sparging means are mounted such that they are immersed in the sample when the shaft is mounted by the mounting means. The electrode assembly further comprises conductor means (44, 46) for electrically connecting the electrode to the electrochemical system. The electrode assembly is rotated during measurement of the concentration of the enzymatic agent. Prior to such measurement, dissolved oxygen may be rapidly removed from the sample by rotating the electrode assembly and introducing an inert gas into the passage, such that the inert gas passes from the rotating sparging means into the sample.

IPC: B01J8/06
Filed: 1986-06-20
Abstract: A convective reformer device(2), which is useful for partially reforming a feed mixture of hydrocarbons and steam, includes an outer shell enclosure(4) and a tubular inner core assembly(6) and is specifically adapted to support heat exchange between a heating fluid, which may be an effluent from downstream, and the hydrocarbon-steam feed mixture. The heating fluid may be directed through the tube portion(24) of the convective reformer(2), or alternatively, through the shell portion(16), either of which may be filled with catalyst. The gas that emerges from the convective reformer(2), which has undergone heat exchange with the feed mixture, may be used to preheat the feed mixture to the convective reformer (2).

Abstract: Un appareil capteur utilise des capteurs à bobine d'induction sans contact pour transférer des informations au sujet d'un paramètre contrôlé d'un organe mobile (18) à des terminaux de sortie (84-87) mécaniquement isolés de l'organe mobile. Chaque capteur à bobine d'induction comprend un circuit bouchon stationnaire (10, 12) et un circuit bouchon mobile (14, 16) couplés par induction pour produire une double courbe de résonance pour le circuit bouchon stationnaire. Le paramètre est détecté par une unité (26, 28, 30) ayant des composants couplés par induction. Cette unité est connecté au circuit bouchon mobile afin de changer l'inductance du circuit mobile en fonction des changements du couplage par induction de unité de détection, qui, à leur tour, dépendent du paramètre contrôlé. A mesure que l'inductance du circuit mobile change, les caractéristiques relatives de fréquence, amplitude et de phase des crêtes de résonance du circuit bouchon stationnaire changent également. Le degré de changement de ces caractéristiques constitue une mesure de paramètre. Afin d'éliminer des erreurs communes de mode, l'unité de détection développe des signaux ayant des directions opposées qui sont multiplexés dans le temps afin de produire des signaux différentiels.

Abstract: Device for quickly and accurately controlling a current through a load impedance, for example a coil of a micro-stepping stepping motor, in which a comparator compares a reference signal with a current measuring signal and, dependent on the sign of the difference, makes the load impedance connect either to the one or to the other of two voltage sources, which are differently polarized with respect to each other, by means of a switching device. In order to avoid too quick a switching the comparator is controlled by an impulse sender, the comparator being able to change its output signal only during and/or a short time after a pulse has been received from the impulse sender.

Abstract: A ring laser gyro path length controller has a cup-like fixture which mounts a piezoelectric actuator and is bonded directly to the gyro block. A mirror assembly is concentrically located within the fixture and is independently mounted to the gyro block thereby enabling independent assembly and disassembly of the fixture and the assembly. Diaphragm sections of the assembly are coaxially positioned and connected to a diaphragm section of the fixture so that bidirectional displacement of the assembly may occur and the moment generated by the actuator results in an axial deflection force on the assembly. A strip of material having a high coefficient of expansion is mounted to the piezoelectric actuator to augment the deflection force as temperature increases thereby reducing the power demands of the actuator.
