Title: Detecteur de rayonnement semiconducteur a grande surface de faib le capacite
IPC: H01L31/10
Filed: 1985-04-25
Granted: 1989-07-19
Abstract: Détecteur semiconducteur de faible capacité pour déceler un rayonnement et des particules (T1), possédant un corps semiconducteur d'un premier type de conductivité (p. ex. type n), sur lequel est appliquée au moins une électrode collectrice pour les porteurs majoritaires. Sur les deux surfaces principales (1, 2) du corps semiconducteur sont prévues des zones d'un second type de conductivité (p+; p+2, p+4) qui forment avec le corps semiconducteur des couches diélectriques polarisées de telle sorte que le corps semiconducteur est pratiquement entièrement appauvri en porteurs majoritaires et qu'un gradient de potentiel (PM) est prévu dans le corps semiconducteur grâce auquel les porteurs majoritaires créés par le rayonnement s'écoulent vers l'électrode collectrice. Un mode de réalisation de la présente invention est caractérisé par le fait que sur l'une des deux surfaces principales (2) entre les zones du second type de conductivité (p+2, p+4) sont prévues des zones du premier type de conductivité (n+1, n+3, n+5) qui sont polarisées dans le sens de non-conduction par rapport aux zones du second type de conductivité, alors qu'est prévue sur l'autre surface principale (1) une zone à grande surface du second type de conductivité (p+) de faible résistance superficielle. Un autre mode de réalisation de la présente invention est caractérisé par le fait que sur au moins l'une des deux surfaces principales entre les zones des deux types de conductivité sont prévues des zones du premier type de conductivité qui sont polarisées dans le sens de non-conduction par rapport aux zones du second type de conductivité, et par le fait que des tensions extérieures ne sont appliquées qu'aux zones d'une surface principale (fig. 3-5).

Title: Procede pour la separation de l'eau obtenue a partir d'un processus de cokefaction en une petite fraction riche en sel et dans une importante fraction pauvre en sel
IPC: C10K1/02
Filed: 1985-06-19
Granted: 1988-10-12
Abstract: Dans le but de séparer l'eau obtenue dans un processus de cokéfaction dans une petite fraction à haute concentration de sel et dans une grande fraction pauvre en sel, on refroidit le gaz brut dans le barillet et on le conduit à travers un filtre électrique, avant d'entrer dans le prérefroidisseur. Le condensat du barillet et l'écoulement de l'électrofiltre sont conduits dans le séparateur de goudron, tandis que le condensat du prérefroidisseur n'est qu'en partie réintroduit dans le circuit du barillet et on obtient un résidu pauvre en sel. Par contre, la phase aqueuse du séparateur de goudron est traitée en partie comme fraction riche en sel; après la sortie du filtre électrique, le gaz brut peut être fractionné dans plusieurs prérefroidisseurs.

IPC: G01R15/20
Filed: 1986-08-27
Granted: 1990-06-13
Abstract: A measuring transformer for measuring a current flowing in an electrical conductor is disclosed. Illustratively, the transformer comprises a three legged ferromagnetic core whose center leg at least partially surrounded by the electrical conductor. The center leg defines a center air gap and two outer air gaps, the center gap containing a magnetic field snesor and one outer gap being located at each end of the center leg. The two outer gaps are longer than the center gap when measured in the longitudinal direction of the center leg. The center leg and the magnetic sensor may form a single construction element. This configuration permits an especially precise, simple, and dependable installation of the measuring transformer, without worsening non-linearities or phase errors, while improving air-gap tolerances.

Abstract: A hand knife (20, 120), of the type having a ring-like rotary driven blade useful for cutting meat and other suitable products; a blade housing (24, 124, 224) for a hand knife; and a circular blade (26, 126). The blade housing has a generally circular groove (38, 138, 238) to receive a ring gear portion (56, 256) of the blade while a cutting portion (60) extends from the housing. One arcuate wall portion (38b, 138b, 238b) of the housing is frusto-conical and faces a similarly contoured peripheral portion of the blade ring-gear. In the preferred construction the housing recess is formed by a cylindrical wall that surrounds the ring-gear portion of the blade and by a frusto-conical wall that is encircled by the ring-gear portion of the blade. A blade retainer (28, 128) secured to the handle acts against a radial flange (62, 162) of the blade when tightened, to retain the blade within the groove, and when loosened allows removal of the blade from the housing.

Granted: 1990-09-26
Abstract: Built-up or facing material is melted in an electric arc between a parent member and at least one electrode movable relative to the parent member. As the electrode moves, at least one welding parameter is varied in a predetermined zone of movement in order to form an open channel. After passing this zone, the original welding parameters are restored and a former is placed over the channel to complete the cross-section of the channel. Welding continues until the required wall member has been reached. The former can be subsequently removed by dissolving or decomposition. The open channels may receive neutron-absorbent material where the member is used as a cylindrical storage receptacle for nuclear fuel elements.

Title: Process and apparatus for the continuous filtration of liquids
IPC: B01D29/62
Filed: 1987-05-14
Granted: 1990-11-28
Abstract: By this method, the fluid to be filtered is led through a filter bed formed of particulate filter particles, such as sand, which filter bed is retained in an upstanding annular space. The fluid is introduced to the interior part 15 of the annular space and is led transversely to the movement the filter bed, through it and away. The filter bed is provided on the inner wall of annular space with a microfilter, such as sieve grid 16, with a mesh size of 10 to 200 microns, whereby the heavy and flocculated dirt particles settling upon the microfilter are led down and away and are drawn off together with the particulate filter particles 32. To avoid stoppages of the microfilter, it is flowingly hydraulically cleaned from the inner space. Additionally, by introduction of water in the take-off space 11 there is produced a vortex bed, whereby at this space the withdrawal of the particulate filter medium is effected with a mammoth pump 17 known per se. The compressed air for the operation of the mammoth pump 17 is supplied not steadily but pulsatingly. Thus, there are provided in the vortex bed in combination with the water supply thereto some hydraulic pulses which serve to hinder the development of bridges in and above it.

Granted: 1991-11-21
Abstract: La centrifugeuse de décantation (1) décrite comprend une vis transporteuse (5) formant un corps évidé ayant une densité moyenne inférieure à la phase liquide la plus légère de la boue environnante. La vis transporteuse (5) s'écoule par conséquent dans ladite phase liquide, laquelle est utilisée de telle sorte que le seul palier radial traditionnel de la vis transporteuse est remplacé par un palier de support radial (22), qui ne coopère avec la vis transporteuse (5) que lors de la mise en marche et de l'arrêt de la centrifugeuse, lui évitant ainsi d'entrer en contact avec le bol (2). Pendant le fonctionnement, la vis transporteuse n'est, par conséquent, soutenue que dans la direction radiale à l'une de ses extrémités, ce qui a pour conséquence que la rigidité de fléxion de la vis transporteuse devient moins importante que le nombre de révolutions maximum authorisé de la centrifugeuse, ledit nombre pouvant ensuite être augmenté pour une centrifugeuse donnée, ce qui permet d'obtenir un effet de séparation amélioré.

Title: Process for hardening moulding sand articles
IPC: B22C9/12
Filed: 1988-09-24
Granted: 1991-04-24
Abstract: A process is described for curing sand moldings, in particular casting cores, by the cold box process. In this process a catalyst containing gas mixture escaping from the mold is passed over a mixture feed side of a semipermeable membrane while a pressure is maintained on the permeate side of the membrane which is less than the pressure on the mixture feed side, whereby the catalyst vapors preferentially permeate through the membrane, and a permeate carrier gas stream which is, in particular, 50 to 300 liters greater than the permeate stream passing through the membrane per m2 and per hour is passed over the permeate side of the membrane. The catalyst, in particular a tertiary amine, is greatly concentrated in the permeate carrier gas stream and can simply and inexpensively be removed from the latter by condensation. Inexpensive, virtually complete recovery of the expensive catalyst is possible using the process.
