Abstract: An improvement in the degree of separation is obtained by using a separation-effective material on which the finest suspended particles can adhere and coagulate to form larger droplets. Brush bodies 4 are used as the separation-effective material in the separation space. With a vertical arrangement of the brush bodies 4 consisting of a central carrier 4' and radially outward-pointing bristles 4", cleaning by a stripping device consisting of a mobile ring body 5 and to be actuated vertically is possible.

Abstract: Zur Verbesserung der dynamischen Eigenschaften von Thyristoren kann es erwünscht sein, die Speicherladung in Emitternähe abzusenken. Dies kann dadurch erreicht werden, daß der Emitterwirkungsgrad bei hoher Stromdichte durch Kurzschlüsse verschlechtert wird. Katodenseitig sind die Kurzschlüsse derart aufgebaut, daß in der Emitterzone hochdotierte Kurzschlußgebiete (4) angeordnet sind. Die Kurzschlußgebiete (4) werden von Zwischengebieten (5) überlappt, die den gleichen Leitungstyp wie die Emitterzone haben. Die nicht überlappte Fläche ist wesentlich kleiner als die Fläche der Kurzschlußgebiete (4). Damit ist bei geringer Stromdichte die kurzschließende Fläche klein, bei hoher Stromdichte groß. Ähnliche Kurzschlüsse sind auch anodenseitig anwendbar.

IPC: A47J37/04
Filed: 1989-01-24
Abstract: A continuous convection oven includes rotatable substantially horizontal perforated cylinders (25), each forming a cooking chamber having an inlet (27) and outlet (28), and a removable helical conveying member (35) mounted for rotation with each cylinder, extending at a helix angle opposite to the direction of rotation. High temperature air is directed through a bottom area of the cylinder and impinges directly against the food product therein. The rate of food product movement is controlled according to the type of product being cooked, temperature of circulated air and appropriate cooking time for that product. 
     Side walls of the helical member (35) urge the product toward the outlet and rotation of each cylinder causes product being carried up the cylinder wall to tumble over and forwardly upon itself. The space between turns of the helical member serves as a conveying channel (38). Portions of the food product are grouped by the helical member, and each group is constantly tumbled both laterally and forwardly in the channel. Simultaneously, heated air impinges on all sides of the product, to cook evenly all sides of an irregular or many-sided food product. Grouped food portions are dis­charged as an essentially continuous stream, so that operation of the oven is essentially continuous from the standpoint of product input and delivery. A cycle control operates the oven in cooking and self-cleaning modes. In the self-cleaning mode a heater is operated at a temperature sufficient to assure pyrolytic cleaning of interior exposed parts of the oven cavity and cooking chamber, and also actuates a blower and a drive for the cooking chamber during cleaning mode.

Title: Filtre de reduction de rayonnement utilise dans le diagnostic medical
Inventor: DEMONE KENNETH E
IPC: G21K3/00
Filed: 1989-01-27
Abstract: Un filtre à rayons X réduit sensiblement le rayonnement de faible puissance normalement absorbé par l'objet de l'examen, sans affecter de manière significative le rayonnement de forte puissance voulu. Le filtre se compose d'un ou de plusieurs matériaux (12) comprenant à titre de constituant principal des éléments choisis dans le groupe composé d'aluminium, et d'éléments dont le nombre atomique est compris entre 26 et 50. On choisit le filtre pour que ses caractéristiques de filtration des rayons X réduisent d'environ 8 à 35 % les niveaux de rayonnement normaux de l'intensité des rayons X ayant des puissances de 50 KeV. Le résultat de cet agencement est que le filtre de cette invention filtre la puissance du faisceau de rayons X normalement absorbée par l'objet de l'examen, et n'a aucun effet sur l'image radiographique dudit objet. On parvient à ce but en augmentant peu ou pas la charge du tube de rayons X, autrement la durée de vie de ce dernier serait réduite.

Abstract: An IDT electrode (4) is formed on a double-layer structure comprising a diamond crystal layer (2) and a thin AIN film (3) and a third-order Rayleigh or Sezawa wave is caused to propagate along the surface of the double-layer. Alternatively a third-order Rayleigh wave is caused to propagate along the surface of a triple-layer structure comprising a diamond crystal layer (2), a thin AIN film (3) and an SiO 2  film provided therebetween. With the aforementioned structure, a SAW device exhibiting a high electromechanical coupling factor and a high phase velocity is available. The SAW device for allowing a third-order Rayleigh wave to propagate along the surface thereof is fit for use as a narrow-band timing extraction filter or a band-pass filter, for use in a microwave region of several to 20 GHz whereas the SAW device for allowing the Sezawa wave to propagate therealong is fit for use as a wide-band voltage control oscillator or a wide-band-pass filter for use in wide range of frequencies covering VHF to UHF bands.

Filed: 1990-03-05
Abstract: An elevator system employing a micro-processor-based group controller communicating with the cars to assign cars to hall calls based on a Relative System Response (RSR) approach. However, rather than using unvarying bonuses and penalties, the assigned bonuses and penalties are varied using "artificial intelligence" techniques based on combined historic and real time traffic predictions to predict the number of people behind the hall call, and calculating and using the average boarding and de-boarding rates at "en route" stops and the expected car load at the hall call floor. Prediction of the number of people waiting behind hall calls for a few minute intervals are made using traffic levels measured during the past few time intervals on that day as real time predictors, using a linear exponential smoothing model, and traffic levels measured during similar time intervals on previous similar days as historic traffic predictors, using a single exponential smoothing model. The remaining capacity in the car at the hall call floor is matched to the waiting queue using a hall call mismatch penalty. The car stop and hall stop penalties are varied based on the number of people behind the hall call and the variable dwell times at "en route" stops. The stopping of a heavily loaded car to pick up a few people is penalized using a car load penalty. These enhancements to RSR result in equitable distribution of car stops and car loads, thus improving handling capacity and reducing waiting and service times.

Abstract: A process for the preparation of catalysts wherein a catalytically effective amount of cobalt is impregnated and dispersed as a film, or layer, on the peripheral outer surface of a particulate porous inorganic oxide support, notably alumina, silica, silica-alumina and titania; particularly titania. The catalysts are prepared by spraying a bed of the fluidized particular support particles with a liquid containing a dispersed or dissolved cobalt metal compound upon the support particles. The operation is performed at specified operating conditions. Novel catalyst particles having a thin film of catalytically-active metal in the outer layer only of the particle are described. Such particles are useful in synthesizing hydrocarbons from CO and H₂ mixtures.
