Inventor: PASCHKE RICHARD H
IPC: A61C3/025
Filed: 1997-08-06
Abstract: In a tooth cleaning system having a flexible protective shield, and a nozzle having an end portion extending into the shield. The shield is connected to a source of vacuum and has an inner wall having an inner wall perimeter. The nozzle is connected to a fluid source. The fluid from the fluid source travels directly from the nozzle to less than half of the area enclosed by the perimeter. The improvement includes pivotally supporting the nozzle whereby the nozzle is readily repositioned to positions angularly offset from the central axis of the shield directing fluid from the nozzle to the entire tooth surface and enclosed by the perimeter. The perimeter forms a fluid tight seal with the tooth outer surface. The invention provides a method of cleaning teeth including providing a flexible plastic shield having a nozzle channel therethrough and a rigid nozzle extending through said nozzle channel. The flexible protective shield is positioned against a tooth surface and the pressure within the chamber formed by the flexible protective shield and the tooth surface is reduced to a pressure below atmospheric pressure. Cleaning the entire tooth surface area by bending the nozzle channel and maintaining a fluid tight seal at the perimeter of the protective shield.

Patent CA-2273893-A1 (CA)
Inventor: ADKINS STEPHEN BRYAN
IPC: B65F1/14
Filed: 1999-06-08
Abstract: The invention provides a refuse and recyclable materials collection system which includes a self-dumping bin, a hauling unit with a tailgate and an opening top, side or both, a compacting ram that empties the hopper into the body, compacts and ejects the collected materials. The collection vehicle is placed into a loading position, which can be on either side of the vehicle. For collection of two different types of recyclable materials the collection vehicle can be equipped with two receiving doors, hoppers, rams, compacting chambers and tailgates. The self-dumping bin receives power by connecting hydraulic lines from the collection vehicle. The self-dumping bin is then raised to the dumping position by a lifting mechanism. The receiving door opens to form a chute for receiving the materials from the self-dumping bin. A baffle on each of the receiving doors forms a trap to prevent spillage. The bin has a tapered "lip"that funnels the material into the hopper of the hauling unit. The bin is moved into a tipping position allowing the materials to empty from the bin into the hopper of the collection vehicle. As the hopper is filled the ram manually or automatically cycles to empty the hopper and compact the material. The loaded vehicle is then transported to either a landfill for refuse or a material recycling facility for recycling. The collection vehicle can be a trailer, which is towed by a truck or a body mounted on a truck chassis.

Abstract: A contour emphasizing circuit in which VE and detected by vertical contour component detecting unit 10 and a horizontal contour component detecting unit 12 are added by a first adder 14 and then multiplied by a coefficient, and the product is added to an input video signal by a second adder 16 to output an emphasized-contour video signal, the circuit comprises a comparing/judging unit 15 for comparing VE with HE and judging whether or not the absolute value of the difference between them is smaller than a preset value S, and a coefficient change-over multiplier unit 17 for changing the coefficient by which the sum (VE+HE) is multiplied over to K/2 or K according to the judging signal. For a pixel from which both HE and VE are detected, the coefficient change-over multiplier 17 is changed from K or K/2 by judgement signal of the comparing/judging unit 15 to decrease the contour emphasizing component. This prevent excessive contour emphasis of the pixel from which both HE and VE are detected, and natural profile emphasis is carried out.

Abstract: La présente invention concerne une orthèse destinée à une application externe sur le poignet afin de traiter le syndrome du canal carpien. L'orthèse applique simultanément et indépendamment une compression médiane, parallèle et bilatérale le long des extrémités distales du radius, du cubitus ainsi que des parois latérales et médianes des carpes. L'orthèse relâche le retinaculum fléchisseur (les ligaments transversaux et antérieurs du carpe), inverse le prolapsus antérieur du tunnel carpien en prolapsus postérieur et réduit la tension à laquelle sont soumis le nerf médian, les ligaments et la bourse traversant le poignet. Le dispositif est conçu de manière à permettre un mouvement complet et libre du poignet, de la main et des doigts. Ce dispositif utilise un substrat flexible (34) auquel sont attachés des éléments de compression libérables (42, 44) pour le positionnement au niveau de l'extrémité distale du radius et du cubitus au niveau des parois latérales du tunnel carpien. Une boucle de fixation (37) et un élément de fermeture libérable (38, 48) sont intégralement fabriqués dans le matériau du substrat afin de fixer le dispositif autour du poignet de façon telle que la compression et la torsion agissent d'abord sur les éléments avant d'êtres déplacées sur les extrémités du radius et du cubitus. Le dispositif est conçu de manière à être porté aussi bien sur le poignet droit que sur le poignet gauche et s'ajuste aux poignets fins ou gros.
