Title: Verfahren zur klärung von flüssigkeiten, insbesondere rohsaft, sowie anlage zur durchführung des verfahrens
Inventor: GRESCH WALTER
IPC: B01D29/01
Filed: 1988-10-14
Abstract: Nach dem erfindungsgemässen Verfahren zur Klärung von Rohsaft, wird das Retentat einer ersten Querstromfiltra­
tionseinrichtung (2) in die Retentatseite einer zweiten Querstromfiltrationseinrichtung (6) eingeleitet, deren Membranflä­
che (7) eine grössere Porengrösse aufweist als die Membranfläche (3) der ersten Querstromfiltrationseinrichtung (2). Dabei 
wird das Permeat der zweiten Querstromfiltrationseinrichtung (6) zur Retentatseite der ersten Querstromfiltrationseinrich­
tung (2) zurückgeführt. Dadurch entsteht ein Kreislauf (2, 5, 6, 8), in dem der Trub durch ständige Abführung des Restre­
tentats über die Leitung (9) erheblich reduziert wird. Die Folge davon ist eine Verbesserung der Filtrationsleistung und der 
Ausbeute bei relative geringen Investitionskosten.  
     Abstract 
     In a process for clarifying raw juice, the residue from a first cross-flow filtration device (2) is introduced into the res­
idue side of a second cross-flow filtration device (6), the membrane surface (7) of the latter (6) having a greater pore size 
than the membrane surface (3) of the former (2). The permeate from the second cross-flow filtration device (6) is recycled 
to the residue side of the first cross-flow filtration device (2), thereby creating a circuit (2, 5, 6, 8) in which the turbidity is 
substantially reduced due to continuous discharge of the remaining residue through the pipe (9). The result is improved fil­
tration efficiency and yield for a relatively low investment.

Abstract: Un système de fabrication de substrats, notamment plaquettes gauffrées, masques en verre, supports céramiques, comprend des stations individuelles de traitement et/ou de façonnage des substrats individuels dans un environnement stérile et des convoyeurs des substrats entre les différentes stations de traitement. Les stations individuelles de traitement sont pourvues de conduits d'alimentation et d'évacuation (5) qui les alimentent en substances chimiques, gaz, liquides, données et énergie nécessaire et évacuent celles qui ne sont pas nécessaires. Afin de permettre de modifier aisément la suite des opérations de traitement avec une interruption minimale de la production, tous les conduits d'alimentation et d'évacuation (5) sont guidés dans un bus de milieux (3) parallèlement à des modules de traitement (1) agencés dans des stations de traitement échangeables. Des boîtes de couplage (4) sont agencées sur le bus de milieux (3), à des écarts réguliers correspondants aux modules de traitement (1). Un contre-couplage (4') correspondant à chaque boîte de couplage est agencé sur chaque module detraitement (1) aisément échangeable, evéntuellement sur chaque module de milieux (2). La connexion avec les conduits d'alimentation et d'évaluation (5) se fait par assemblage de la boîte de couplage (4) et du contre-couplage (4'), ces connexions étant coupées lorsque l'on sépare les boîtes de couplage (4) des contre-couplages (4').

Title: Microwave radiometer
Inventor: WILEY CARL A
IPC: G01R29/08
Filed: 1988-07-01
Abstract: A microwave radiometer is formed of a set of fre­
quency scanning antennas (26) disposed parallel to each 
other and connected by a common microwave feeder 
(28). Signals of individual ones of the antennas are trans­
lated (36) to different intermediate frequencies such that 
differences between the intermediate frequencies are pro­
portional to baseline spacings between pairs of antennas 
of nested interferometers. A correlator containing parallel 
delay lines and a set of multiplier channels coupled to 
paired taps of the delay lines receives signals at the inter­
mediate frequencies to produce a set of correlation sig­
nals. A two-dimensional Fourier transformation is appli­
ed to the correlation output signals to provide the power 
spectral density of microwave radiation incident upon the 
array of antennas.

Title: Ameliorations relatives au durcissement a induction par balayage
Inventor: BISHOP ARTHUR ERNEST
IPC: C21D9/28
Filed: 1989-02-13
Abstract: On a mis au point un procédé de durcissement à induction par balayage, selon lequel on durcit la surface d'une pièce d'usinage en acier, consistant à faire traverser progressivement la longueur de ladite pièce par une bobine d'inductance excitée par un courant électrique alternatif, et à tremper immédiatement après la partie chauffée de ladite pièce d'usinage, le redressement des courbures dans la pièce d'usinage durcie en surface étant régulé lors du procédé de durcissement à induction par contrôle de la rectitude de la pièce d'usinage et par utilisation des informations ainsi obtenues, afin de réguler le chauffage et la trempe de ladite pièce d'usinage de sorte qu'une couche de matériau durci d'épaisseur supérieure soit formée sur la face concave de n'importe quelle courbure de la pièce d'usinage, de manière à produire un moment de redressement ayant pour effet de faire disparaître la courbure. Ledit procédé se caractérise en ce que la bobine d'inductance est façonnée pour ne chauffer qu'une partie de la circonférence de la pièce d'usinage, ou est façonnée pour concentrer plus de chaleur dans une partie de la circonférence. On fait varier la vitesse de rotation de ladite pièce d'usinage afin que la face concave puisse rester plus longtemps dans la zone de chauffage concentré, et afin que, lors de la trempe, elle reçoive ainsi une couche martensitique plus profonde sur cette face.

Abstract: On a mis au point un procédé de répartition de largeur de bande dans un réseau de commutation par paquets à large bande. Le procédé utilise des groupes de canaux que l'on peut définir comme un ensemble de canaux de paquets parallèles agissant comme une connexion unique de liaison de données entre des commutateurs de paquets. Selon le procédé de l'invention, on répartit la largeur de bande en deux temps. Lors du temps d'établissement des circuits virtuels, la largeur de bande est réservée dans des groupes de canaux particuliers. Lors du temps de transmission, des paquets sont appliqués à des canaux individuels à l'intérieur des groupes. La technique de répartition de largeur de bande connue comme répartition de largeur de bande à canaux multiples, a pour effet d'augmenter le débit et de réduire la perte de paquets.
