Title: Valve, tyre, rim and wheel
Inventor: PALAORO RENATO
IPC: B60C29/02
Filed: 2008-07-18
Abstract: The invention is based on a valve with a valve body (1) having: an air duct (5) which penetrates the valve body (1), in particular in the axial direction (3), and a valve foot (7) which is formed, in particular in one piece, with the valve body (1), on an end (9) of the valve body (1) which is proximal with respect to a rim edge in the installed position, wherein a distal end (8) of the valve body (1) is provided to engage through a valve hole in the rim edge, and the valve foot (7) is provided for arrangement on a tyre-side side of the rim edge. In order to permit easier removal of the valve (10), in particular even on a side of the rim edge facing away from a tyre, the invention provides for the valve foot (7) to be provided to engage through the valve hole, and for a securing element (13) which is separate from the valve body (1) and which projects over the valve foot (7), in particular in the radial direction, to be arranged at the proximal end (9), said securing element (13) being provided for arrangement on a tyre-side side of the rim edge.

Title: Medical devices and methods including polymers having biologically active agents therein
Inventor: MCDONALD PHILLIP EDWARD
IPC: A61K9/14
Filed: 2009-04-17
Abstract: The implant design is a drug loaded polymer device, such as a rod, designed to control the release of a biologically active agent, such as clonidine or its derivatives, such as clonidine HCl for a prolonged period of time, such as 2 months, 3 months, 4 months, and even 4.5 months. The polymer is preferably a biodegradable polymer, such as poly(lactide-co-glycolide) or polylactic acid/polylactide. The challenge in using the HCl salt forms of drugs such as clonidine, is controlling the release of the highly water soluble drug for up to 4.5 months. It has been found that by controlling the particle size distribution of the drug powder, the drug distribution within the polymer matrix is more uniform and can be controlled. Therefore, the large aggregates, which cause rapid drug release can be eliminated.

Title: A smelting process of ferronickel with nickel oxide ore free of crystal water in a blast furnace
Inventor: LIU SHENJIE
IPC: C21B5/02
Filed: 2005-11-02
Abstract: A smelting process of ferronickel with nickel oxide ore free of crystal water in a blast furnace, which comprises breaking and screening the raw ore, preparing agglomerate from the breeze, mixing the agglomerate, coke, limestone/calcined lime, dolomite and fluorite, and smelting them to obtain ferronickel in the blast furnace. The weight ratios of additives to agglomerate are as follows: fluorite 0.3~8%, dolomite 0~8%, limestone/ calcined lime 4~35%. Compared with the prior arts, by means of the ratio of fluorite to agglomerate in the smelting process of the invention, the influence of chromium upon furnace temperature can be reduced, and the burning through accident of hearth due to excessive content of fluorine can be avoided. The magnesium in dolomite can settle the problem of poor fluidity of molten iron caused by the chromium in nickel-chromium ore. Limestone not only provides the basicity but also balances the said additives. The smelting process of the invention is low in cost, and has a high recovery rate of raw material.

Title: Method and apparatus for making acetic acid with improved purification
Inventor: POWELL NATHAN KIRK
IPC: C07C51/44
Filed: 2008-09-18
Abstract: An improved method of producing acetic acid includes condensing overhead vapor from a light ends column and decanting the condensed vapor to a light phase and a heavy phase.

Abstract: PURPOSE: A device for fixing a rolling roll assembly is provided to prevent damage to a cylinder and the leakage of oil by transferring a piston using oil without a spring. CONSTITUTION: A device for fixing a rolling roll assembly comprises a first oil groove(30) which is formed in the center of a cylinder piston fixing the bottom of a rolling roll assembly to transfer the piston to one side, a second oil groove(40) which is formed on one side of the piston to transfer the piston to the other side, a first inflow hole(11) which is formed in a cylinder to inject oil into the first oil groove, a second inflow hole(12) which is formed in the cylinder to inject oil into the second oil groove, and a sealing groove(50) which is formed on one side and the center periphery of the piston to insert a sealing.
