Abstract: L'invention se rapporte à un procédé et à un appareil d'ablation de l'endomètre dans lequel un courant radio-électrique ayant une fréquence comprise entre 250 kHz et 100 MHz traverse toute la surface d'un endomètre afin de fournir de la chaleur à celui-ci. Un élément expansible électroconducteur tel qu'un ballon (14) est utilisé comme milieu de transfert de courant afin de chauffer l'endomètre. La température de l'endomètre s'élève entre 45 degrés Celsius et 90 degrés Celsius et, de préférence, ne dépasse pas 70 degrés Celsius sur une durée suffisante pour détruire les cellules de la muqueuse tout en maintenant la température moyenne du myomètre à une température approximativement inférieure à 42 degrés Celsius. Le ballon dilatable (14) est connecté à une source de courant (197) qui fournit un courant radioélectrique ayant les caractéristiques désirées afin de chauffer sélectivement la muqueuse endométriale à la température désirée.

Title: Water based beverages
Inventor: HUTCHISON KEITH GRAEME
IPC: A23L27/00
Filed: 1994-02-11
Granted: 2004-01-06
Abstract: A method is disclosed of preparing a beverage in the form of a dilute aqueous solution, suspension or dispersion of an encapsulated product. The capsule is added to a potable liquid, and the capsule material breaks down when submerged in the liquid to release its contents and itself dissolve. A primary advantage of providing the product in this way is that it can be confined within the capsule in liquid form, and can therefore disperse or dissolve in water more readily. Additionally, the capsule would normally sink to the bottom of the body of water before releasing its contents, thereby ensuring that the contents are released within the body of water, and not at the surface thereof.

Title: Pressure washer drum
Inventor: TAYLER MARK
IPC: B01D33/067
Filed: 1995-10-31
Granted: 1999-06-01
Abstract: In prior pressure washer drums, the filter deck was supported on the central shaft by spokes welded to the central hub which was in turn welded to the shaft.  The extreme forces caused premature failure of the welded joints.  The present invention provides a pressure washer drum in which sandwic-hed parallel plates having an array of apertures replace the spokes and central pipe and journals are supported on the hub by a bolting system rather than by welding.
Patent CA-2165315-C (CA)

Granted: 2000-10-24
Abstract: L'invention concerne une chambre de pompe pouvant s'aplatir, par exemple en accordéon (40). La chambre de pompe pouvant s'aplatir comporte une paroi latérale pouvant s'aplatir qui délimite le volume interne de la chambre de pompe. La paroi latérale pouvant s'aplatir a une stucture qui s'aplatit suivant un schéma prédéterminé lorsque le dispositif de pompe est actionné. Par exemple, le schéma prédéterminé d'aplatissement peut produire un changement initial relativement faible du volume interne pour une longueur de course donnée, suivi par un changement accru du volume interne pour une longueur de course donnée. Dans ce cas, le dispositif de pompe assure initialement un très bon contrôle de la quantité de produit expulsé, ainsi qu'un dosage précis pour une course partielle. Toutefois, le même dispositif de pompe peut également fournir un grand volume de produit lorsque la course est complète.

IPC: G02B6/26
Filed: 1996-07-12
Granted: 2007-10-02
Abstract: A removable light source is provided for use with the optical coupling system. The light source (24) is mounted to a removable assembly (22) for slidable insertion into, and removed from, a housing (18) containing the optical coupling system. The removable assembly (22) includes positioning elements for maintaining precise alignment of the light source (24) with optical components mounted within the housing (18). In one embodiment described herein, precise alignment is achieved by employing six mounting pads (46) on outside surfaces of a base (26) of the removable assembly (22). Three of the mounting pads (46) are aligned along a first plane (32). Two are aligned along a second plane (36) perpendicular to the first (32). The remaining pad (46) is aligned along a third plane (34) perpendicular to both the first (32) and second planes (36). The light source (24) is mounted to the base (26) in a precise fixed relationship with the mounting pads (46). The removable assembly (22) is inserted within a slot formed in the housing (18) of the optical coupling system. Upon insertion, the mounting pads (46) lie against mutually perpendicular interior walls of a receiving block (28) of the housing (18). The mounting pads (46) thereby ensure that the light source (24) is precisely positioned with respect to the receiving block (28). Optical components within the housing (18) are mounted in a precise fixed relationship with the receiving block (28). Accordingly, while inserted, the light source (24) is maintained in precise alignment with the receiving block (28) and thereby also in precise alignment with the optical components.

Abstract: An axial compliance mechanism for a scroll-type compressor including a fixed scroll member, an orbiting scroll member and a bearing pad spatially fixed in relationship to the fixed scroll member. The axial compliance mechanism biases the orbiting scroll towards the fixed scroll by applying a fluid at high pressure to a radially inner portion of the back surface of the orbiting scroll member and a relatively lower pressure to a radially outer portion of the back surface. An annular stabilization ring is placed between a main bearing pad and the rear surface of the orbiting scroll lifting the orbiting scroll into engagement with the fixed scroll and inhibiting the tilting and wobbling of the orbiting scroll. The annular stabilization ring also maintains a clearance between the rear surface of the orbiting scroll and the main bearing pad thereby improving the performance of a sealing member disposed between the main bearing pad and the rear surface of the orbiting scroll member during start up of the compressor. The annular stabilization ring lifting the scroll member into engagement with the fixed scroll may be located in a shoulder at theouter periphery of the orbiting scroll member or it may form the annular portion of an Oldham ring which controls the orbiting motion of the orbiting scroll member.
