Inventor: PALLAI LASZLO
IPC: F21V21/30
Filed: 2003-01-03
Granted: 2006-08-01
Abstract: The present invention provides an easily assemble swivel mount for supporting a fixture from a support. This swivel mount is of a design such that no tool or special device is needed to either initially position the fixture at a desired location or to change or re-position the fixture should such be desired. A continuous wire passageway is provided through the swivel mount so that no obstacles need be avoided thereby eliminating the possibility that a wire may become kinked within the swivel mount. Such continuous passageway also makes for easy wire insertion through the swivel mount.

Granted: 2007-04-03
Abstract: L'invention concerne une machine-outil multibroches caractérisée en ce que des éléments cylindriques externes (19) à plusieurs broches (2) fixés sur un cadre support (3b) sont introduits dans les trous centraux (2c) des broches, et un dispositif générateur de brume (22) servant à produire une brume lubrifiante dans les broches et les éléments cylindriques internes (20) à l'extrémité desquels se trouve ledit dispositif générateur, ladite machine-outil et ledit dispositif étant installés à l'intérieur des éléments cylindriques externes, de manière à être rétractés avec les éléments cylindriques externes maintenus en position fixe. Ainsi, en position fixe, le dispositif de générateur de brume peut produire de la brume lubrifiante, étant donné que de l'air comprimé et du lubrifiant liquide sont acheminés séparément des parties externes des broches à travers les éléments cylindriques externes et les éléments cylindriques internes. Et, en position rétractée, la brume lubrifiante est acheminée des parties externes vers les parties internes des broches à travers les éléments cylindriques externes, de manière à faire gicler la brume des embouts des organes de coupe fixés sur les embouts des broches. On peut modifier un système de génération de brume pour le faire passer d'un système de génération de brume interne en un système d'alimentation en brume externe par le biais d'une opération simple, et on peut réaliser l'opération d'optimisation du flux de la brume lubrifiante par giclage, rapidement et à moindre coût.
Patent CA-2456056-C (CA)
Inventor: HATTA NAOKI
IPC: H01M4/58
Filed: 2002-07-31
Granted: 2011-11-15
Abstract: Disclosed is a process for producing a secondary battery cathode material by calcining raw materials. The process is characterized by calcining the raw materials together with one or more substances, which are selected from the group consisting of hydrogen, water and water vapor, and conductive carbon and/or a substance, which can form conductive carbon by pyrolysis, added thereto. As crystals of the secondary battery cathode material obtained by this process have been controlled fine sizes, the secondary battery cathode material promotes movements of ions of an alkali metal led by lithium between the interiors of grains of the cathode material and an electrolyte to suppress polarization in an electrode reaction, and further, increases an area of contact between the positive material and a conductivity-imparting material to provide improved conductivity so that improvements are assured in voltage efficiency and specific battery capacity.

Title: Floor cleaning apparatus with pivotal handle
Inventor: CROUCH JAMES T
IPC: A47L9/32
Filed: 2004-03-08
Granted: 2007-06-05
Abstract: A floor care apparatus has a handle, connected to a hose, that pivots about an axis substantially perpendicular to a longitudinal axis of a terminal end of the hose. In this manner, the hose experiences less mechanical stress during use and, when embodied on a canister vacuum cleaner, a nozzle assembly connected to the handle has less tendency to tip over. Preferably, the hose has a cuff mounted at the terminal end with a hose insert therein. The hose insert has two stub shafts on opposing sides of an opening that form a journal defining the handle pivoting axis. The handle has two mating sections that clamshell about the journal and pinch it in place. Each mating section has a bearing surface for receipt of the journal and, when embodied as a cylinder, terminal ends of the journal become inserted therein.

Title: Skin lesion exciser and skin-closure device therefor
Inventor: BANBURY JILLIAN ELIZABETH
IPC: A61B17/068
Filed: 2002-09-30
Granted: 2008-12-16
Abstract: A skin lesion exciser including a moving blade, wherein excision of a skin lesion placed in proximity to the blade is effected by movement of the blade against the skin, a moving engagement portion, wherein the blade and the engagement portion have coincident movement, and a skin-closure device having an open condition prior to excision of the skin lesion, and a closed conditions in which the device holds the skin closed after excision of the skin lesion. The device is in engagement with the engagement portion during movement of the blade, and the device is moved from its open to its closed condition in response to movement of the engagement portion. The excision of the skin lesion and the closure of the skin are substantially simultaneous.  The present invention also provides a method for excising a skin lesion including: positioning a skin lesion above a moving blade; slicing the lesion from the skin with the blade; and substantially simultaneously with excision of the lesion, closing the skin beneath the moving blade. The present invention also provides a skin-closure device which may be used in conjunction with an inventive exciser.

Title: Carbon dioxide foamed fluids
Inventor: CHEN YIYAN
IPC: C09K8/70
Filed: 2004-06-04
Granted: 2010-10-26
Abstract: An aqueous viscoelastic surfactant (VES) fluid foamed or energized with carbon dioxide, in which the VES is more compatible with the carbon dioxide, is made by the addition of one or more than one synergistic co-surfactant. The synergist co-surfactant includes quaternary amines and ethoxylated carboxylates having a hydrophobic chain shorter than the hydrophobic chain of the VES. Improved compatibility is evidenced for a given surfactant concentration either by formation and maintenance of a foam under conditions at which the foam could not otherwise have been formed or maintained, or by either higher viscosity of the foamed fluid at a given temperature or longer foam life at a given temperature or a higher temperature at which useful fluid viscosity can be generated or maintained for a useful time. The aqueous carbon dioxide foamed fluids may be used in acidizing, acid fracturing, gravel packing, diversion, and well cleanout.
