Abstract: Cette invention se rapporte à un procédé perfectionné de fabrication de polymères qui consiste à utiliser au moins un monomère non saturé éthyléniquement et au moins un agent de surface polymérisable. Ledit agent de surface polymérisable est susceptible de subir une copolymérisation avec des monomères classiques et il est de préférence presque complètement consommé au cours de la polymérisation. Les polymères produits conformément à ce procédé sont particulièrement adaptés à l'utilisation dans des revêtements, adhésifs, produits de scellement et élastomères.

Abstract: A spa cover remover has a pair of parallel side bars pivotably connected to opposite sides of a spa, and a cross-bar in the form of a roller extending between upper ends of the side bars. In use, a spa cover is folded over the cross-bar during removal from a spa, and the side bars and the cross-bar are then pivoted to lift the cover into an offset position.  During such pivotation, rotation of the roller prevents stretching and consequential damage of the covering of the spa cover.

Title: A fluid-activatable vane for a fluid turbine
Inventor: BIC ADRIAN
IPC: F01D7/00
Filed: 1999-08-24
Granted: 2007-07-03
Abstract: A fluid-activatable vane is defined by a thin vane body having opposed narrow leading and trailing side edges and opposed substantially smooth large top and bottom surfaces. The body has a central longitudinal axis and is substantially symmetrical on opposed sides of the axis. An attachment shaft is aligned with the central axis at a near end edge of the vane to secure two diametrically opposed vanes through a coupling wherein the vane will tilt along a 90° arc from a horizontal plane to a vertical plane when exposed to a fluid flow. The two vanes form a propeller and are fixed to a respective end of the attachment shaft in a respective plane and offset 90° from one another. A fluid actuatable torquing curved outer end edge portion is formed integral with the vane body in an outer end edge portion thereof and on a respective side of a central longitudinal axis. The curved outer end edge portions also project from a respective one of the top and bottom surfaces with the curved outer end edge portion adjacent the leading edge projecting upwardly from the vane when the vane is disposed horizontally when secured to a drivable vertical shaft of a turbine.

Title: Die wall lubrication method and apparatus
Inventor: MONGEON PAUL-EMILE
IPC: B30B15/00
Filed: 2000-11-02
Granted: 2004-01-27
Abstract: A method of lubricating the wall surfaces of a die cavity used in powder metallurgy involves spraying the wall surfaces with tribocharged particles of a lubricant material. The method is carried out by means of an apparatus centered about a plug member which has a three-dimensional shape conforming generally to that of the article to be formed. The plug member is slightly smaller than the article so that when the plug member is inserted into the die cavity there is a small, but uniform, gap created between the outer wall surfaces of the plug member and the walls of the die cavity. The plug member is secured to a closing plate which can be inserted into the die cavity so as to be sealed therewith. The closing plate is provided with vent holes and the plug member has a plurality of spaced apart tubes extending therethrough, which tubes exit at one or more of the wall surfaces of the plug member. The lubricant material is fed using an inert gas under pressure through tubing which tribocharges the lubricant particles and the tribocharged particles are sprayed from the tubes in the plug member into the gap so that they are electrostatically attracted to the walls of the die cavity and adhere thereto.  Any excess gas and lubricant exits the gap through the vent holes in the closing plate. A uniform thin coating of lubricant is created on the walls of the die cavity. The green density of the article formed in the die is greater, and the ejection force required to remove the formed article from the die cavity is less, than with existing methods and apparatus.
