Patent CA-2488099-A1 (CA)
Inventor: KNOBLOCH ARTHUR R
IPC: F15B3/00
Filed: 2004-11-23
Abstract: A residential water pressure booster is disclosed comprising a housing with a primary inlet attached to a water source and with an outlet supplying the residential water use. Some of the energy of the flowing water is captured by a turbine impeller that is mounted on a drive shaft. The drive shaft transmits this energy to a pump impeller and, in the preferred embodiment, to a centrifugal pump impeller, both of which boost the pressure of the liquid. Water pressure is also increased by a constriction chamber which constricts the flow between the turbine impeller and the pump impeller. The efficiency of the pump impeller is increased by the action of the centrifugal pump impeller and directional fins and directional grooves in the constriction chamber, which impart a rotational motion to the liquid. The device efficiently boosts water pressure with an external power source.

Title: Boissons contenant des sterols vegetaux
Inventor: LERCHENFELD ERICH P
IPC: A23L1/30
Filed: 2003-06-11
Abstract: L'invention concerne un procédé permettant de produire une dispersion sensiblement stable sans auxiliaires technologiques. Cette dispersion est principalement composée d'un stérol végétal hydrophobe et d'une matière aqueuse, le stérol végétal étant choisi parmi les stérols végétaux et les stanols végétaux. Ce procédé consiste à mélanger le stérol végétal avec une matière aqueuse afin de former une première dispersion. Les étapes suivantes consistent à chauffer cette première dispersion afin de former un mélange chauffé, puis à homogénéiser ce mélange chauffé afin d'obtenir une seconde dispersion de particules. La taille des particules de stérol végétal hydrophobe dans la première dispersion et dans la seconde dispersion est comprise entre 0,1 microns et 30 microns environ. Dans une forme de réalisation, la matière aqueuse est constitué principalement d'un concentré de boisson comprenant un concentré de jus tel qu'un concentré de jus d'agrume, p. ex. un concentré de jus d'orange. L'invention concerne également un produit obtenu avec ce procédé et une composition de substances constituée d'une dispersion sensiblement stable d'un stérol végétal hydrophobe et d'une matière aqueuse, le stérol végétal étant choisi parmi les stérols végétaux et les stanols végétaux. Pour éviter sensiblement que la dispersion ne produise une sensation poudreuse, la taille des particules de stérol végétal est comprise entre 0,1 micron et 30 microns environ, et la majorité de particules de stérol végétal comprises dans cette plage mesurent entre 0,2 micron et 10 microns environ, et respectent sensiblement une courbe de distribution en forme de cloche. Cette composition peut être produite au moyen du procédé décrit.

Title: Integral titanium boride coatings on titanium surfaces and associated methods
Inventor: AICH SHAMPA
IPC: B32B15/04
Filed: 2003-11-17
Abstract: A borided titanium article can include a titanium mass having titanium monoboride whiskers infiltrating inward from a surface of the titanium mass to form an integral surface hardened region. The titanium mass can be almost any titanium based metal or alloy such as high purity titanium, commercial grade titanium, a-titanium alloy, .alpha.+.beta. titanium alloy, .beta.-titanium alloy, titanium composite, and combinations thereof. Borided titanium articles can be formed by methods which include providing a titanium mass, contacting a surface of the titanium mass with a boron source medium, and heating the titanium mass and boron source medium to a temperature from about 700 ~C to about 1600 ~C. The boron source medium can include a boron source and an activator selected to provide growth of titanium monoboride whiskers. The boron source medium can be provided as a solid particulate mixture, liquid mixture, or as a gaseous mixture. During heating, boron from the boron source infiltrates into the titanium mass and forms titanium monoboride whiskers which improve the surface hardness, wear resistance, oxidation resistance, and corrosion resistance of the treated surface. The titanium monoboride whiskers can be controlled to have the desired dimensions, depending on the application requirements. Boriding titanium surfaces using these methods, provides a relatively inexpensive and effective process for improving the surface properties of titanium which are then useful in a wide variety of applications.
