Patent EP-0276296-A4 (EP)
Title: Current-limiting circuit
IPC: G05F1/56
Filed: 1987-08-05
Abstract: A subscriber power controller device for converting a high voltage at a S interface into a stable, regulated low voltage to be used by integrated circuits in an ISDN terminal includes a control logic circuit for generating an output signal to control the duty cycle of an output transistor in an output driver circuit. The control logic circuit is responsive to a ramp signal, an error signal, a high reference voltage signal, a low reference voltage signal and a synchronizing signal for generating the output signal. The output signal is in the form of a pulse train in which each pulse thereof is variable in width dependent upon the error signal. A current-limiting circuit is provided and is responsive to output current of the output transistor for generating a current-limiting signal when the output current exceeds a certain preset limit. The control logic circuit is responsive to the current-limiting signal for automatically terminating each pulse of the pulse train in the output signal on a pulse-by-pulse basis when the output current exceeds the preset limit.

Filed: 1987-09-15
Abstract: Conjointement avec un appareil de thermofixage (10) de fils de tapis (17) comprenant une chambre à pression (22) ayant une surface supérieure poreuse (22d) associée à un système à courant d'air forcé (33) pour remettre le milieu de chauffage en circulation sur tout la longueur de la chambre de thermofixage (10), une conception améliorée de la chambre à pression (22) et de la distribution du milieu de chauffage permet de compenser le gradient de température présent jusqu'à maintenant dans la chambre de thermofixage (10) et dû à l'introduction de fils refroidis (17) dans la chambre (10). Ce gradient de température provoquait, lors de l'arrêt de la machine, des striations de la teinture dues à l'exposition du fil (17) à des températures relativement plus basses à côté de l'entrée de la chambre de thermofixage (10).

Patent EP-0369020-A4 (EP)
Title: Device for detecting the position of a machine
IPC: G05B19/21
Filed: 1989-03-28
Abstract: A device for detecting the absolute position of a moving part of a machine using a rotary encoder. The object is to detect any error that may develop in the content stored in the absolute position storage means. A register (4) stores the absolute position of when the power source circuit is closed and the present absolute position that is detected by a rotary encoder (2) based on the subsequent amount of movement. A counter (5) counts the quantity of shift from a position of generating a one-turn signal of the rotary encoder (2). When the moving part stops, a coincidence circuit (6) collates the present position stored in the register (4) with the counted content of the register (5), and generates an error signal when they are not in agreement. Therefore, the machine tool and the like are prevented from erroneously operating.

Title: Method of purifying lacustrine water and filthy water purification boat
IPC: C02F1/52
Filed: 1991-04-09
Abstract: A method enabling thorough purification of lacustrine water with simple operation in an energy-saving manner within a short period of time and being free from the possibility of secondary public nuisance, and further a filthy water purification boat for implementing said method. According to this invention, while operating a filthy water purification boat having an electrolyzing device for calcium fluoride, DC current power source, and coagulant pouring device mounted thereon on lakes or marshes, the electrolyzing device is operated and coagulant is fed into a pipe having a coagulant pouring nozzle. Lacustrine water, while passed through electrodes, is fed with fluorine ion and coagulant, and polluting substances coagulate and turn into flocks of a large diameter. These diametrally large flocks are recovered into the boat by a flock recovering device or adapted to sink to the bottom of lakes or marshes after volume reduction caused by hydrophobic action of the flocks, and purified water is returned to lakes or marshes.
Patent EP-0521084-A4 (EP)
Title: Method and apparatus for rendering anti-aliased polygons
IPC: G06T11/60
Filed: 1991-02-15
Abstract: The pixels which comprise the edges and vertices of a polygon are determined from the vertices of the polygon (300). The alpha channel comprises either a sub-pixel mask which indicates the amount and sub-pixel regions of coverage or a single value indicative of the percentage of coverage of a pixel. The pixel between the edge pixels of the polygon are turned (310), thereby filling the polygon. The pixels of the polygon are then composited with the background pixels. A depth (Z) value of each pixel determines the equations used (320, 330, 350, 370) to composite polygon to the background, updating the color of the pixel, the z buffer value of the background pixel and the sub-pixel mask (340, 360, 380, 390). Through this single pass method high quality anti-aliases polygons may be rendered without performing the time consuming process of sorting the polygons in depth order prior to compositing.

Patent EP-0624226-A4 (EP)
Inventor: BECK NEILS J
IPC: F02M63/00
Filed: 1992-06-25
Abstract: Cette invention concerne une série de perfectionnements apportés à un procédé et à un appareil utilisés dans le domaine des injecteurs de carburant du type à accumulateur, pouvant s'appliquer aux injecteurs à accumulateur renforcés et non renforcés, qui coopèrent pour améliorer fortement l'économie de la consommation en carburant des moteurs à combustion interne, pour réduire le bruit, et pour réduire les émissions indésirables d'échappement telles que la fumée, les oxydes d'azote et les hydrocarbures. Dans cette invention on augmente la vitesse de fermeture de l'aiguille d'injecteur pour que la coupure de l'alimentation en carburant soit plus nette et pour que l'atomisation soit meilleure à proximité de la fermeture, et on minimise le choc de la fermeture de l'aiguille pour réduire au minimum la production de gouttelettes de carburant à proximité de la fermeture en réduisant le volume et la longueur de l'aiguille (110), qui se présente alors sous la forme d'une aiguille (110, 136) divisée dans le sens longitudinal. L'amortissement hydraulique amortit et atténue à la fois la fermeture et l'ouverture de l'aiguille d'injecteur.

Title: Immobilized mismatch binding protein for detection or purification of mutations or polymorphisms
Inventor: WAGNER ROBERT E JR
IPC: C12Q1/6858
Filed: 1994-11-04
Abstract: A method for detecting mutations, such as a single base change or an addition or deletion of about one to four base pairs, is based on the use of an immobilized DNA mismatch-binding protein, such as MutS, which binds to a nucleic acid hybrid having a single base mismatch or unpaired base or bases, thereby allowing the detection of mutations involving as little as one base change in a nucleotide sequence. Such a method is useful for diagnosing a variety of important disease states or susceptibilities, detecting the presence of a mutated oncogene and for isolating or removing by affinity chromatography duplex DNA molecules containing mismatches such as error-containing molecules in PCR-amplified DNA samples. Also provided are kits useful for practicing the methods of the present invention.
