Patent CA-2254793-A1 (CA)
Title: Brosse a dents electrique
Inventor: WONG TIT SHING
IPC: A61C17/26
Filed: 1997-05-12
Abstract: L'invention concerne une brosse à dents électrique comportant une brosse rotative entraînée mécaniquement. Le sens de rotation de la brosse est commandé automatiquement en fonction des dents à brosser, selon qu'il s'agit des dents du haut ou des dents du bas, afin d'enlever tous les débris alimentaires sur les dents et les gencives, dans une direction s'éloignant des gencives. La brosse à dents, selon l'invention, utilise un élément de commande de direction qui est placé à l'intérieur de la bouche entre les dents du haut et les dents du bas. L'élément de commande de direction commande le sens de rotation de la brosse et permet de stabiliser cette dernière par rapport aux dents au cours de l'opération de brossage. Le mouvement de l'élément de commande de direction actionne un inverseur de marche pour changer le sens de rotation de la brosse et assurer un brossage dans un sens s'éloignant des gencives et en direction des dents sans devoir pour autant retirer la brosse à dents de la bouche.

Title: Strain relief assembly for welding cable
Inventor: FOSTER WILLIAM C JR
IPC: B23K9/133
Filed: 1998-03-04
Abstract: A strain relief assembly (60, 60') reduces bending of a welding cable (26) which delivers welding wire (38), gas, and electricity from a welding machine (30) to a welding gun (24) and includes first (62) and second (64) strain relief elements surrounding and extending along the welding cable (26) for supporting and providing strain relief to the cable (26) and a connector (66) attaching the strain relief elements (62, 64) to the machine (30) and/or the gun (24). The first strain relief element (62) extends a first distance from the connector (66) for supporting the cable (26), reducing bending of a first portion of the cable (26) positioned inside the first strain relief element (62). The second strain relief element (64) extends a second distance, greater than the first distance, from the connector (66) for supporting the cable (26) and the first strain relief element (62), thereby reducing bending of the first portion inside the first strain relief element (62) and a second portion of the cable (26) inside the second strain relief element (64).

Patent CA-2266073-A1 (CA)
Inventor: HOEY MICHAEL F
IPC: A61B18/14
Filed: 1996-10-02
Abstract: An electrocautery instrument (10) is provided with a source of conductive fluid coupled to a proximal end of a hollow electrode (16). Conductive fluid is communicated through said electrode (16) and expelled out of the distal end thereof during electrocautery, forming a "virtual electrode". The infused conductive liquid conduits the RF  electrocautery energy away from the conductive electrode (16), thereby displacing the region of thermal generation and reducing the extent of burns and perforations caused by conventional electrocautery electrodes. In one embodiment, the electrode (16) is partially disposed within and extends distally out of a retractable suction tube (14), such that smoke and fluid are aspirated from the electrocautery site. When the suction tube (14) is fully advanced, the electrode (16) is concealed therein, enabling suction without electrocautery to be performed.

Abstract: L'invention porte sur des aliments pour animaux complémentaires en minéraux et protéines et résistant aux intempéries, et sur leurs procédés de fabrication. Un prémélange d'oligo-éléments se présentant sous forme de granules à écoulement libre est produit en série selon un procédé consistant à: (1) mélanger un liant liquide avec un ingrédient d'apport de granules relativement grossiers de façon à obtenir des noyaux humides recouverts d'un liant, (2) tandis que les noyaux humides recouverts d'un liant sont mélangés à un mélange de base d'oligo-éléments, (3) les noyaux et leurs couches externes d'oligo-éléments sont mélangés à des substances qui confèrent aux gaines une résistance à l'eau, et (4) une poudre est appliquée pour achever la formation des granules constitués du prémélange d'oligo-éléments. Les granules du prémélange sont mélangés à des ingrédients d'apport macrominéral sous forme de grains grossiers, à de l'oxyde de fer et à une solution d'enrobage résistant à l'eau de façon à former des granules d'apport minéral résistant aux intempéries. Selon une réalisation préférée, on forme les gaines résistant à l'eau en mélangeant le produit de l'étape (2) avec un acide gras et en y déposant un oxyde métallique avec lequel il réagit. Dans une autre variante, les granules du prémélange sont mélangés avec des ingrédients d'apport macrominéral sous forme de granules grossiers, avec de l'oxyde de fer, des liquides y compris une solution d'enrobage résistant à l'eau, et avec un ou plusieurs ingrédients protéiniques de façon à former des granules d'apport complémentaire en protéines résistant aux intempéries.

Patent CA-2268687-A1 (CA)
Inventor: JACKSON RALPH
IPC: G01F23/296
Filed: 1999-04-14
Abstract: The invention provides apparatus for sensing the level of contents in a container comprising a body (20); a diaphragm (50) having first and second faces; two probes (40) connected to the first face of the diaphragm for mechanical oscillation thereon; two actuating arms (59, 56) fixed to the second face of the diaphragm each in a position opposite that at which a respective probe is fixed; and a stack (70) comprising one or more driving transducer and/or one or more receiving transducer, the stack functioning such that the or each receiving transducer generates a voltage in response to a change in compressive force between ends of the stack and such that a voltage applied to the or each driving transducer causes the length of the stack between its ends to change. Ends of the stack (70) are connected to the actuating arms (54,56), and are subject to a compressive force. Vibration of the probes (40) causes consequential vibration of the actuating arms (54,56) to cause modulation of the compressive force applied to the stack (70).

Title: Coated corrugator belt
Inventor: LANTHIER JOSEPH D
IPC: B65G15/54
Filed: 1999-04-16
Abstract: A corrugator belt for a corrugator machine includes a base having two sides. One of the two sides is the face side of the corrugator belt when the belt is in the form of an endless loop on a corrugator machine. A layer of polymeric resin material is coated onto the face side of the base. The polymeric resin material provides the corrugator belt with an increased coefficient of friction relative to corrugated board, enabling the belt to pull corrugated board more readily through a corrugator machine.

Filed: 1999-07-30
Abstract: A method and apparatus for introducing an oxidant mixed with a carrier gas into pre-heating zone of a continuous furnace for effectively removing lubricant from powder metal compacts prior to sintering at high temperatures. Mixing a controlled amount of a gaseous oxidizing agent such as moisture, carbon dioxide, air or mixtures thereof with a carrier gas and introducing the mixture into the preheating zone of a continuous furnace under controlled conditions accelerates removal of lubricant from powder metal compacts prior to sintering at high temperature by decomposing lubricant vapors into smaller and more volatile hydrocarbons, produces sintered components with close to soot- and residue-free surfaces and with the desired physical properties, prolongs the life of furnace components including muffles and belts, and reduces downtime, maintenance and operating costs.
