Patent CA-2783110-A1 (CA)
Inventor: ARMSTRONG JONATHAN
IPC: F04D29/38
Filed: 2012-07-11
Abstract: There is provided an impeller arrangement (200) for location in an impeller housing (102, 104) delimiting a housing inlet (110), the impeller being rotatable about an axis of rotation (X-X) and comprising a base (206), a shroud (208) and a plurality of blades (210) located therebetween, the shroud (208) comprising an impeller inlet (212) defining a passageway extending to the plurality of blades (210), wherein the impeller arrangement (200) further comprises a barrier arrangement (214) located adjacent the impeller inlet (212) and arranged to receive, or extend into, a portion of the impeller housing (102, 104) surrounding the housing inlet (110) to restrict airflow between the impeller housing (102, 104) and the shroud (208). By providing such an arrangement, inlet losses to the impeller can be reduced when compared to known arrangements. A barrier arrangement provided on the shroud of an impeller is located in close relationship with a complementary portion of the volute adjacent the air inlet. The interaction between these components forms a barrier to bleeding of the airflow away from the inlet, reducing the likelihood of air passing between the shroud and volute housing and improving the inlet efficiency of the impeller.

Title: Thermally switched absorptive window shutter
Inventor: POWERS RICHARD M
IPC: G02B27/28
Filed: 2008-12-22
Abstract: A thermally switched absorptive optical shutter (100) may be a self-regulating "switchable absorber" device that may absorb approximately 100% of incoming light above a threshold temperature, and may absorb approximately 50% of incoming light below a threshold temperature. The shutter (100) may be formed by placing a thermotropic depolarizer (102) between two absorptive polarizers (101, 103). This control over the flow of radiant energy may occur independently of the thermal conductivity or insulation of the shutter device (100) and may or may not preserve the image and color properties of incoming visible light.  This has energy-efficiency implications as it can be used to regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. It also has aesthetic implications since the shutter device (100) has unique optical properties that are not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or walls. Additionally, the shutter device (100) may have application as a building material.

Title: Multi-function rear seat structure mechanism
Inventor: RUNDE DAVID M
IPC: B60N2/12
Filed: 2012-08-27
Abstract: A seat assembly includes a seat cushion and seat back supported above a floor by a rear leg. The seat back is pivotally coupled to a recliner bracket. The seat cushion is selectively pivotally locked relative to the recliner bracket. A disc recliner operatively couples the recliner bracket and rear leg. The disc recliner allows the rear leg to pivot relative to the recliner bracket to move the seat assembly from a design seating position to a slouch position. The seat back is pivoted towards the seat cushion and the recliner allows the rear leg to pivot relative to the recliner bracket, thereby lowering the seat assembly to move the seat assembly to a fold and kneel position. The seat cushion is unlocked relative to the recliner bracket to pivot the seat cushion towards the seat back to move the seat assembly to a stadium position.

IPC: E05B17/00
Filed: 2014-03-17
Abstract: A door lock chassis has a gauge insert that defines different dimensions corresponding to different door thicknesses. The gauge insert is positionable in the lock chassis in different orientations corresponding to the different dimensions used to align the lock chassis for different door thicknesses. Additionally, a door lock may include an anti-rotation assembly for preventing rotation of the lock chassis.
