Patent CA-2309672-A1 (CA)
Title: Procedes et appareil de commande d'un compresseur d'air dans le systeme de lavage d'une garniture de forage
Inventor: CHEERS RONALD M
IPC: E21B21/16
Filed: 1998-12-02
Abstract: L'invention concerne un système de lavage destiné à fournir de l'air comprimé à une garniture de forage, afin de balayer les déblais de forage produits au cours d'une opération de forage. Ce système comprend un compresseur d'air pourvu d'une soupape d'admission située à l'entrée de ce compresseur, et d'une soupape de sécurité située à la sortie dudit compresseur. Ces soupapes sont placées en état de marche normal, mais une fois actionnée, ladite soupape d'admission permet de réduire le volume d'air admis, et ainsi de faire diminuer le volume et la pression de l'air évacué. Si l'alimentation en air de lavage dirigé vers la garniture de forage est temporairement réduite ou coupée alors que ledit compresseur est en marche, la pression de l'air s'accumule pour être ensuite dirigée vers la soupape d'admission et la soupape de sécurité, de manière à réduire le volume et la pression de l'air provenant de la sortie du compresseur. On peut ainsi faire baisser considérablement l'énergie nécessaire pour alimenter ce compresseur.

Inventor: PRIESE LUTZ
IPC: B07C5/342
Filed: 1998-11-13
Abstract: The invention relates to a method for identifying and sorting objects which are conveyed on a belt, especially for sorting waste. The nature of the material that the objects consist of is determined spectroscopically using an NIR measuring device (13) and the objects are sorted according to the result of the spectroscopy in that they are removed from the conveyor belt (7, 8, 9).  According to the invention, the shape and/or the nature of the surfaces of the objects and the position of the objects on the conveyor belt (7, 8, 9) are determined (12) before the nature of the material that they consist of. The objects are then scanned by the measuring point (19) of the NIR measuring device (13) according to at least their position and removed from the conveyor belt (7, 8, 9). This guarantees a high identification and sorting rate and ensures that the system functions reliably.

Title: Imaging and characterization of brain tissue
Inventor: CHANCE BRITTON
IPC: A61B5/145
Filed: 1999-02-11
Abstract: An optical examination technique employs an optical system (15, 45, 100, 150, 200, 260 or 300) for in vivo non-invasive transcranial examination of brain tissue of a subject. The optical system includes an optical module (12 or 14) arranged for placement on the exterior of the head, a controller and a processor. The optical module includes an array of optical input ports and optical detection ports located in a selected geometrical pattern to provide a multiplicity of photon migration paths inside the biological tissue. Each optical input port is constructed to introduce into the examined tissue visible or infrared light emitted from a light source. Each optical detection port is constructed to provide light from the tissue to a light detector. The controller is constructed and arranged to activate one or several light sources and light detectors so that the light detector detects light that has migrated over at least one of the photon migration paths. The processor receives signals corresponding to the detected light and forms at least two data sets, a first of said data sets representing blood volume in the examined tissue region and a second of said data sets representing blood oxygenation of the examined tissue. The processor is arranged to correlate the first and second data sets to detect abnormal tissue in the examined tissue.

Patent CA-2322506-A1 (CA)
Inventor: STEINHARDT MARK JOHN
IPC: A61K8/00
Filed: 1999-02-26
Abstract: An anhydrous lotion composition for killing viruses and bacteria in addition to imparting a soft, lubricious, lotion-like feel when applied to tissue paper and tissue paper treated with such lotion compositions are disclosed. The antiviral action of the lotion is due to the addition of an organic acid such as citric acid or salicylic acid. The antibacterial action is due to the addition of antibacterial agents such as TRICLOSAN®. The solubilization of the antiviral and antibacterial agents within the lotion matrix is aided by the addition of hydrophilic solvents and hydrophilic surfactants. The lubricious lotions also contain a plastic or fluid skin conditioning agent such as petrolatum, an optional immobilizing agent such as a fatty alcohol or fatty acid to immobilize the skin conditioning agent on the surface of the tissue paper web and a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided. The anhydrous nature of the lotions also aids in the maintenance of such physical properties as tensile and caliper.

Title: Loose lamination die with rotating blanking station
Inventor: BENDER MARK
IPC: B21D28/22
Filed: 2000-11-02
Abstract: In a method and apparatus for rotating loose laminations in a die, a strip is fed to a rotatable blanking chamber of a blanking station. A punch punches a lamination free from the strip. The rotatable blanking chamber is biased in an upwardly direction. When the punch is not engaging, the rotatable chamber is in an upward position wherein a gap develops between laminations retained at a bottom of the rotatable chamber, and those laminations lying directly below the rotatable chamber. The rotatable chamber can then be rotated without damage to the laminations at the gap because of the gap. Thereafter, a succeeding lamination can be punched after the rotation has occurred. As the punch engages the strip, the rotatable chamber is pushed downwardly so that the gap at the bottom of the rotatable chamber disappears.

Abstract: The present invention provides heavy duty long life corrosion inhibition formulations and compositions for inhibiting mineral scale and the corrosion of metals particularly the cavitation corrosion of aluminum in the presence of aqueous liquids. The combination of a mixture of polymeric polycarboxylates, azoles, a combination of nitrite and nitrate salts, phosphates, stabilized silicates and transition metal compounds provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations and varying pH ranges.  The addition of selected polymeric polycarboxylates not only significantly reduces glycol based coolant cavitation erosion-corrosion, heat rejecting aluminum corrosion, and hard water precipitates and scale, it has been discovered that polymeric polycarboxylates in combination with siloxane stabilized silicates enhance secondary silicate stabilization leading to improvement in an aluminum corrosion protection and coolant life when utilized with selected amounts of the above-identified additives. The formulations are particularly suitable for automotive applications.
