IPC: G09F15/00
Filed: 2005-05-06
Abstract: Outer (12) and inner (14) inflatable members and a motor assembly including a fan are disposed on a base member (18). Air provided under pressure by the motor assembly including the fan passes through vents in the base member (18) to inflate the inflatable members (12, 14). Flakes (16) are disposed in the space between the inflatable members (12, 14). One vent, larger than the others, provides for the flakes (16) to be lifted upwardly from the base member (18) by the pressurized air. At least another vent in the base member (18) provides for a movement of the flakes (16) by the pressurized air in an annular direction in the space between the inflatable members (12, 14). A  permeable cap (60) disposed on the outer inflatable member (12) limits the pressure in the outer (12) and inner (14) inflatable members to a particular value.

Title: Method and apparatus for applying dynamic loads to a locked gear train for testing power transmission components
Inventor: PETERSON CHRISTOPHER E
IPC: B60K17/00
Filed: 2004-11-09
Abstract: An apparatus for testing power transmission components of a locked gear train having two helical gears coupled on a first shaft meshed with two helical pinions coupled on a second shaft, with the two gears arranged to axially translate (while rotating) with respect to the two pinions when a linear force is applied to a thrust bearing at an end of the first shaft. The axial displacement of the two gears causes torsional displacements of the meshed gear and shaft elements, creating a dynamic torque within the locked train assembly. Under rotation, this dynamic torque subjects the components within the locked gear train to a much higher power level for testing.

Title: Automatically sliding windows without sash
Inventor: YU JINZHANG
IPC: E06B3/66
Filed: 2005-07-14
Abstract: The present invention relates to an automatically sliding window without sash, comprising a frame body having an upper slide groove and a lower slide groove formed therein, and an intelligent drive mechanism being disposed at an upper portion of the frame body and driving a window body to move horizontally. The window body includes a pane and roller members fixed to a lower edge portion of the pane, and the drive mechanism is engaged to an upper edge portion of the pane. The area of the window according to the present invention allowing the sunlight to pass through is increased significantly compared to those windows in the art since each window body almost completely consists of glass. The closing and opening of the window body can be controlled more conveniently by utilizing an intelligently controlled transmission mechanism. The sealing of the window is improved since a bidirectional multiple sealing is applied between the groove and the pane or the panes.  The window according to the present invention can be maintained more conveniently. The present invention provides a window with a novel configuration and a good appearance, which overcomes all the shortcomings of a window having a window body with sashes in the art.

Title: Resin curable butyl rubber compound and curing bladders made therefrom
Inventor: VAN ASBROECK ELKE
IPC: C08J3/24
Filed: 2007-03-14
Abstract: A resin curable butyl rubber compound particularly suitable for use in tire curing bladders. The compound includes butyl polymers having unsaturation levels in excess of 1.50 mol% and from 0.5 to 2 phr of a 2-hydroxybenzyl alcohol. The alcohol helps to reduce the level of unsaturation in the compound during resin curing, which is advantageous in improving oxidative resistance of the compound without comprising the critical physical properties that lead to improved curing bladder cycle life.  This allows commercially available grades of butyl to be used that have higher levels of unsaturation than are typically tolerated in curing bladder applications.
