Title: Method for laser surface hardering profile of tooths of gear- wheel and device for its realization
Inventor: KHARALAMPIEV ILIJA S
IPC: C21D9/32
Filed: 1987-05-29
Abstract: By using this method and the device you will reach a uniform hardening of the surfaces of the processed teeth. By this method two laser rays focused on the opposite sides of the involuting profile of two different none-neighbouring teeth, one of the rays is pointed towards the tip of one of the teeth and the other ray - towards the base of the other tooth. By the linear shape of the spot of the laser ray, which has a length equal to the width of the tooth the trajectory remains unchanged and by a point shape of the spot, the ray scans the width of the profile, as at the same time the gear wheel performs two cinematically joined motions - step-rotary and axis shifting, in order for the laser ray to travel over the involution profile. The laser rays always remain perpendicular to the surface being hardened and with a constant length of the ray in both cases. The device consists of two main units - an establishing and a working. The establishing unit includes a manipulator (17) for delivery of the gear wheel (1) on a movable table (8), a mechanism for assuring the step-rotary motion (9,10,11) of this table (8) and the second mechanism for the shaft drive (15,16,20) of the same table simultaneously with its step rotation in direction I of the laser rays coming from the laser sources (2,2<I>), fitted in the processing unit including except the mechanism for their fitting (3,4,5,6,7) also the mechanism for their radial focusing (4,12,13,14,19).

Inventor: TODESCAT MARCIO LUIZ
IPC: F04B39/00
Filed: 1997-05-07
Abstract: Cette invention se rapporte à un système d'aspiration pour un compresseur hermétique à mouvement alternatif, comprenant une enveloppe hermétique (21), comportant un tube d'entrée d'aspiration (28) pour l'admission du gaz; un orifice d'aspiration (24a), qui est placé à la tête d'un cylindre (22) disposé à l'intérieur de l'enveloppe et qui se trouve en communication par fluide avec le tube d'entrée d'aspiration (28). Ce système comprend un moyen d'aspiration (60) ayant une première extrémité (61) et une seconde extrémité (62) qui sont couplées de façon hermétique au tube d'entrée d'aspiration (28) et à l'orifice d'aspiration (24a), respectivement, afin de conduire le gaz sous basse pression depuis le tube d'entrée d'aspiration (28) directement jusqu'à l'orifice d'aspiration (24a), de façon à assurer une isolation thermique et acoustique pour le gaz aspiré.

Title: Systeme de verrouillage et de blocage de seringues jetables
Inventor: DE PAIVA MARQUES JOSE LUIZ
IPC: A61M5/50
Filed: 1998-01-30
Abstract: Cette seringue jetable auto-verrouillable à usage unique comprend un cylindre, un plongeur et un élément de verrouillage pour éviter une aspiration ultérieure. L'élément de verrouillage comprend des griffes élastiques à expansion radiale reliées au plongeur et sollicitées les unes contre les autres par une bague de retenue afin de les empêcher d'entrer en contact avec la paroi intérieure du cylindre. Pendant la course d'injection, le frottement entre la bague de retenue et la paroi latérale intérieure du cylindre est plus grand que le frottement entre la bague de retenue et les griffes. Par conséquent, la bague de retenue reste stationnaire à l'extrémité proximale du cylindre, les griffes se détachent de la bague de retenue et s'écartent radialement, à cause de leur élasticité, accrochant la paroi latérale intérieure du cylindre et empêchant la tige du plongeur de revenir en arrière, ce qui ne permet pas de recharger la seringue. En outre, si l'on essaie de forcer le plongeur à revenir en arrière afin de recharger la seringue, les griffes percent le cylindre de la seringue à cause de leurs extrémités acérées. Les frais de production de l'élément de verrouillage sont très bas.

IPC: H04N5/345
Filed: 2002-01-21
Abstract: L'invention concerne un système et des procédés qui permettent de contrôler un capteur d'imagerie équipé d'un obturateur à rideau, en réduisant au minimum les retards associés à la modification des paramètres d'image de l'obturateur (temps d'intégration, taille de fenêtre et temps de suppression). Les modifications de paramètre interviennent entre trames successives, en mode continu, une fois lue la dernière trame et avant la remise à l'état initial de la trame suivante. En utilisant des décodeurs et des compteurs d'adresse séparés pour les signaux de remise à l'état initial et de lecture, on permet au signal de remise à l'état initial de poursuivre jusqu'à la trame suivante avant la lecture complète de la trame antérieure. Par ailleurs, une indication est fournie quant à la nécessité d'appliquer les signaux de remise à l'état initial et de lecture à chaque trame en fonction de telle ou telle modification de paramètre, et selon l'augmentation ou la diminution d'un paramètre donné.

Title: Method for injection moulding blanks and gate system
Inventor: HOFSTETTER OTTO
IPC: B29C45/20
Filed: 1989-10-04
Abstract: The method is used to process a synthetic moulding compound which crystallizes within a specific temperature range. In order to prevent milkiness in the blank to be produced, the moulding compound is chilled. The method according to the invention prevents such milkiness, at least in the gate area of the blank, by keeping all of the moulding compound, during the operating cycle, as far as the gate area, at a temperature which is above the temperature T CC below which the moulding compound begins to crystallize. A gate system, which may be used to carry out the method according to the invention, comprises, in the interior of the injection nozzle, a strongly heat conducting nozzle core, a strongly heat conducting area in the immediate vicinity of the gate opening, and a gap for heat insulation of the nozzle tip, the nozzle core and the moulded body.

Date Jun. 28, 1990.Prereduced iron oxides are supplied to a smelting vessel (1) for the production of iron or steel by directing a hot reducing offgas from the vessel (1) into a vertical riser duct (8) without substantial cooling of the offgas and by way of inlet (16), particulate iron oxide containing material is entrained in the hot reducing offgas as the gas is conveyed upwardly through the duct (8). The hot gas heats the entrained material to a temperature at which partial reduction of the iron oxide occurs, the hot gas thereby, losing sensible heat. Additional materials may be introduced to the duct (8) for entrainment in the gas. Particulate material is separated in a cyclone (9) from the gas and the separated partially reduced material is introduced to the smelting vessel by way of passage (12). The particulate material, or part of it may be recycled by way of passage (15) through the vertical rise duct before the partially reduced material is introduced to the smelting vessel and only part of the hot reducing offgas emitted by the vessel may be directed into the duct.

Title: Method for reducing skew image artifacts in helical projection imaging
Inventor: CRAWFORD CARL R
IPC: A61B6/03
Filed: 1990-02-15
Abstract: Abstract of the Disclosure A method of reducing image artifacts in tomographic projection imaging systems where the projection data is acquired using continuous gantry motion and using a variable table velocity to transport the object imaged object past the rotating gantry.  The table velocity is decreased when the projections are being acquired near the slice plane and increased when the projections being acquired are further from the slice plane.  The table position is coordinated with the acquisition of projections so that the middle projections of the tomographic projection set are acquired close to the slice plane and the beginning and end projections are acquired when the projections are taken furthest from the slice plane. Interpolation procedures are used to further reduce image artifacts resulting from the taking of projection data at points removed from the slice plane.
