Abstract: L'invention concerne un procédé de conversion d'huile lourde ou de résidu pétrolier en hydrocarbures gazeux et distillables avec un rendement énergétique optimisé. Ce procédé se caractérise en ce que: a) on porte à 350-450.degree.C un mélange d'une charge d'huile lourde et/ou de résidu pétrolier avec une première fraction d'huile de recyclage hydrogénée, puis on le mélange avec un gaz réducteur contenant de l'hydrogène, du monoxyde de carbone et de la vapeur d eau, admis à une température d'au moins 800.degree.C, de manière à porter la température du mélange résultant charge + gaz à une valeur comprise entre 530 et 850.degree.C sous une pression d'au moins 20 bars, pendant un temps de 0,1 à 60 secondes; b) on mélange le produit résultant de l'étape (a) avec une seconde fraction d'huile de recyclage hydrogénée dont la température est inférieure à 300.degree.C, et abaisse aussi la température dudit produit jusqu'à une valeur inférieure à 450.degree.C, puis on met le produit résultant en contact direct avec un courant de gaz renfermant de l'hydrogène et de la vapeur d'eau, de manière à vaporiser au moins 80% du liquide présent à une température inférieure à 450.degree.C, et on sépare la phase gazeuse résultante d'une fraction non-vaporisée de brai et/ou de coke; c) on traite la fraction lourde de brai et/ou de coke par l'oxygène et la vapeur d'eau dans les conditions de l'oxyvapogazéification du carbone, pour la convertir au moins en partie en un gaz réducteur comprenant de l'hydrogène, du monoxyde de carbone et de la vapeur d'eau et on envoie au moins une partie de ce gaz réducteur, dont la température est d'au moins 800.degree.C, à l'étape (a); d) on fait passer la phase gazeuse de l'étape (b), renfermant de l'hydrogène, du monoxyde de carbone, du dioxyde de carbone, de la vapeur d'eau et des vapeurs d'hydrocarbures, sur un catalyseur d'hydrogénation, dans des conditions d'hydrogénation; e) on fractionne les produits de l'étape (d) en une phase gazeuse, une phase aqueuse, une fraction d'hydrocarbures liquides légers distillant normalement, au moins en majeure partie, au dessous de 250.degree.C et une fraction d'hydrocarbures liquides lourds distillant, au moins en majeure partie, au-dessus de 250.degree.C, et dont le rapport atomique H/C est entre 1,2 et 1,7; f) on traite la phase gazeuse de l'étape (e) de manière à éliminer au moins la plus grande partie du dioxyde de carbone et de l'hydrogène sulfuré qu'elle contient et on en recycle au moins une partie à l'étape (b); et g) on recycle aux étapes (a) et (b) au moins une partie de la fraction lourde, distillant en majeure partie au-dessus de 250.degree.C, obtenue à l'étape (e), pour constituer au moins une partie desdits courants d'huile de recyclage hydrogénée.

Abstract: SELF-CLEANING COLLECTING DEVICE              ABSTRACT OF THE DISCLOSURE A self-cleaning collecting device for cleaning a dirty gas stream including a flow-through housing having a dirty gas inlet at the base of the housing and a clean gas outlet at the top of the housing interconnected by a gas treating passage adapted to direct a gas stream vertically through the housing.  As the dirty gas stream enters the housing, it is circulated through a liquid bath where noxious vapors and larger particulates are entrained in a mist of liquid droplets which are in turn captured and removed from the gas stream as it moves through a separating panel positioned above the liquid bath.  As the gas flows upwardly out of the panel, the captured liquid is circulated to the liquid bath to maintain a flow of liquid within the panel which acts to continuously wash the particulates from the panel.  At the same time, the gas stream continues upwardly in the treating passage where it flows through an electrostatic precipitator which removes the smaller particulates from the gases prior to their being discharged from the housing through the gas outlet at the top of the housing.

Abstract: ROOM TEMPERATURE CRYOGENIC TEST INTERFACE                   Abstract This interface permits the testing of high speed semiconductor devices (room-temperature chips) by a Josephson junction sampling device (cryogenic chip) without intolerable loss of resolution.            The interface comprises a quartz pass-through plug which includes a planar transmission line inter-connecting a first chip station, where the cryogenic chip is mounted, and a second chip station, where the semiconductor chip to be tested is temporarily mounted.  The pass-through plug has a cemented long half-cylindrical portion and short half-cylindrical portion.  The long portion carries the planar transmission line, the ends of which form the first and second chip mounting stations.  The short portion completes the cylinder with the long portion for part of its length, where a seal can be achieved, but does not extend over the chip mounting stations.          Sealing is by epoxy cement.  The pass-through plug is sealed in place in a flange mounted to the chamber wall.            The first chip station, with the cryogenic chip attached, extends into the liquid helium reservoir.      The second chip station is in the room temperature environment required for semiconductor operation.          Proper semiconductor operating temperature is achieved by a heater wire and control thermocouple in the vicinity of each other and the second chip mounting station.            Thermal isolation is maintained by vacuum and seals.            Connections for power and control, for test result signals, for temperature control and heating, and for vacuum complete the test apparatus.

Abstract: Abstract of the Disclosure Electromagnetic Relay The invention relates to an electromagnetic relay in which the magnet yoke (18), with the aid of lateral projections (28, 29) is positionally fixed in cut out portions (26, 27) provided in the side walls of a housing member. When looked at in the longitudinal direction (25) two cut out portions (26, 27) are provided for behind each other, in each of which there is a supporting web (31, 32). The one of these cut out portions (26), together with the supporting web (31), serves as the swivel point for the magnetic system and the other one of the cut out portions (27), together with its supporting web (32) is positioned in such a way that the mag-netic system is in such an installation position that, in the state of rest of the armature (19), the contacts (11, 12, 13, 14) are in the operative position. By deforming the cut out portion (27) owing to a bulging of the cover portion (5) and the supporting web (32), the magnetic system is pressed in the downward direction and, in the course of this, swivelled about the supporting point (33). Upon or after reaching the switchover point of the contacts (11, 12, 13, 14),the adjusted position is assumed and the further de-formation is stopped. In this way it is possible to achieve a simple adjustment of the magnetic system (15) relative to the contact system (8).            (Fig.1)

Abstract: ABSTRACT      With a servo system for positioning a transducer of a rotatable storage apparatus over a servo tracks of a magnetic disk,  a  mehthod  for  processing  trains  of positioning  pulse signals is provided.  With a fixed duration time, a reference voltage, changing with time, having a predetermined pattern is generated and compared with a train of the positioning pulse signals contained in the duration time.   The magnitude of the positioning signals which varies with the displacement of the transducer  from  a guide  path  to  be  followed  is  given  by counting the number of the positioning signals exceeding the reference voltage pattern.  Thus, an error signal for the servo system is fed back in a digital form.  The method causes cost reduction  of  the  apparatus  because  of  its  simplicity  and flexibility for the users' demand.
