Patent CA-2238539-C (CA)
Title: Appareil de dispersion a haute pression et a plusieurs chambres
Inventor: OGIER RAY
IPC: B01F13/06
Filed: 1997-02-06
Granted: 2005-06-07
Abstract: Procédé et appareil permettant de mélanger au moins deux matériaux difficiles à mélanger. L'appareil comporte une enveloppe cylindrique (20) divisée en une chambre supérieure (42) et une chambre inférieure par un séparateur (40). Les matériaux à mélanger sont introduits sous pression dans la chambre inférieure, qui est divisée en zones de pression (64) par des déflecteurs cinétiques (58). Une ailette de turbine (66) fournit de l'énergie aux liquides, que les déflecteurs cinétiques (58) empêchent de tourbillonner. La haute pression des matériaux introduits dans la chambre les oblige à traverser un orifice (44) situé entre le déflecteur (40) et l'ailette faisant tourner l'arbre (66), ce qui les fait passer dans la chambre supérieure (42). Dans cette dernière, une seconde ailette (80) fournit aux matériaux une force centrifuge qui les oblige à sortir. Les matériaux sont cisaillés au moment où ils traversent le dispositif, puis ils sont amenés à un orifice de sortie (50).

Granted: 2004-04-06
Abstract: The sample dilution module includes an oil filled aspiration probe and mixing chamber that communicate with each other while the mixing chamber is maintained at an angle of approximately 5 to 45 degrees below a horizontal axis. The aspiration probe is maintained in a vertical orientation. A micro-bubble is aspirated between separate aspirations of test sample and diluent to prevent contact between the sample and diluent in the aspiration probe. The test sample and diluent are then drawn from the vertically oriented aspiration probe into the mixing chamber. After the sample and diluent are in the mixing chamber the micro-bubble of air can migrate away from the test sample and diluent to enable the test sample and diluent to contact each other. Mixing of the test sample and diluent is accomplished by moving the test sample and diluent back and forth in the mixing chamber without physical agitation of the mixing chamber and without any mixing element in the mixing chamber. Such movement is accomplished by alternate suction and vacuum forces imposed on the fluid in the mixing chamber.

Abstract: The invention relates to a knee orthosis preventing hyperextension, i.e.  excessive extension of the knee joint. The invention comprises a top portion (1) to be secured at the patient's thigh and a lower portion (2) to be secured at the patient's lower leg, a joint portion (10) connecting the top and lower portions, and strap means (3-9) for securing the orthosis. According to the invention the joint portion has two axes (11, 12) preventing hyperextension but otherwise allowing a free motion of the patient's leg.  Preferably, the joint portion comprises two hinges (10) connected together by a connection bar (14) positioned in or near the popliteal space. In a preferred embodiment, the top and lower portions comprise brace members (1, 2) having ventral and dorsal slits (19) for the strap means.  The ventral and dorsal slits are positioned at the different height and may be offset from the centre line of the orthosis. The two-axes joint allows a natural joint motion and the connection bar provides the required stability. The orthosis is light-weight and made of few components. The orthosis allows easy donning and doffing by incorporating adequate straps.
