Title: Aeration device with a protection skirt
Inventor: DESJARDINS GAETAN
IPC: C02F3/16
Filed: 1988-06-09
Granted: 1994-07-12
Abstract: ABSTRACT          An aeration device is immersed in an aeration-sedimentation basin for oxygenating the water contained therein. The aeration device comprises a vertical, hollow aeration column with a lower inlet and an upper outlet. A pipe supplied with pressurized air has an orifice to produce in the column an upward jet of air.  A skirt surrounds the lower portion of the column including the inlet, which skirt has a closed, lower end but an open, upper end above the level of the solid accumulations in the basin.  Water substantially free from solid accumula-tions is therefore pumped by the air jet through the open, upper end of the skirt and the water inlet, the pumped water flowing through the column from the inlet to the outlet while being oxygenated by the air jet, and the so oxygenated water being returned in the basin through the outlet.

Abstract: L'invention concerne un procédé de traitement permanent d'un liquide tel que de l'eau en vue de sa purification par émission in situ d'ions métal à partir d'électrodes plongées dans un courant de ce liquide et portées à des potentiels électriques différents. Il est caractérisé en ce que l'on fait varier la tension électrique entre les électrodes en fonction de deux paramètres qui sont respectivement la résistance électrique instantanée du liquide et la distance linéaire relative séparant les surfaces des électrodes en présence, afin qu'à chaque instant la tension électrique entre les électrodes soit telle que le courant reste sensiblement constant et que l'émission d'ions métal dans le liquide reste sensiblement égale à une valeur prédéterminée. De préférence, on fixe une valeur au courant électrique et l'on fait varier sa tension en fonction des variations de la résistance existant entre les électrodes. Ce procédé s'applique à la purification et à la stérilisation de liquides tels que de l'eau ou du lait et, en particulier, au traitement de l'eau des piscines en supprimant tout emploi de produits chimiques.

Title: Method and system for recording image data by thermal  head
Inventor: INOUE NOBUHIRO
IPC: B41J2/36
Filed: 1989-03-17
Granted: 1994-01-18
Abstract: Abstract of the Disclosure A thermal recording apparatus records image data line-by-line, using a thermal head having a linear array of heating elements.  Each of the heating elements is shorter in the sub scan direction than in the main scan direction.  To form an image of one recording line, the feeding of a recording paper and the transfer of ink onto the paper are repeated a plurality of times -- for example, two times -- using the image data for that line.  The excellent thermal response of the heating element constructed as above, and the use of a plurality of recording operations for one recording line image formation, provides a uniform recording density distri-bution curve, so that the recorded image has high image quality and is substantially free from recording density irregularity.  An additional recording control employed eliminates a nonimage part which will occur due to a varied recording speed.

Abstract: The present invention relates to artificial onlay tooth crowns or inlays composed of a prefabricated core designed for preparations for onlay tooth crowns or inlays in natural teeth. The core is preferably fabricated from a high strength densely sintered ceramic material by copy milling from a negative reproduction from the prepared cavity to a compacted body or a presintered ceramic material. During the copy milling the sintering shrinkage is considered by enlargement of the copy milled compacted body or the presintered body corresponding to the sintering shrinkage. The onlay tooth crowns and inlays are given the final shape by shaping the surfaces outside the cavity of the compacted or the presintered body. After the final sintering the external surface can be shaped before a veneer material is attached to the external surface of the core by e.g. firing of dental porcelain. To manufacture onlay tooth crowns or an inlay according to the method of the invention decreases essentially the manufacturing time for onlay tooth crowns and inlays and at the same time the strength and the accuracy to shape increase.
