Patent CA-2565156-A1 (CA)
Inventor: MILLER RICHARD JOHN
IPC: B64C25/42
Filed: 2005-05-10
Abstract: In the field of avionics, it is difficult to justify initiation of new aircraft programmes for replacement of small numbers of niche aircraft.  Instead, in many cases, retrofitting existing aircraft is preferred for economic reasons. In this respect, upgrading existing braking systems to accommodate replacement of existing brake units employing sintered friction materials with brake units employing carbon-carbon composite friction materials is desirable. However, when upgrading the braking systems it is necessary to ensure that the integrity of the existing airframe is not compromised by the use of the new brake assemblies employing the carbon-carbon composite friction materials. Consequently, the present invention replaces existing pressure control valves of existing braking systems with an electronic control unit (126) coupled to a pressure control servovalve (128), thereby ensuring proper application of hydraulic pressure to brake assemblies (122). An advantage of this invention is that the pressure profile of the hydraulic fluid is controllable and hence the integrity of the airframe is maintained.

Title: Positive action lock for sliding windows
Inventor: BESTLER WILLIAM
IPC: E05C3/22
Filed: 2007-02-28
Abstract: A sliding window having a pair of sashes with a latch mechanism on the meeting rail of one of the sashes for latching the sashes together. To open the window, the latch mechanism is disengaged by grasping a finger grip on a latch handle to retract a latch bolt. As one or more of the sashes is slid to open the window and the latch mechanism clears the meeting rail of the other sash, a trigger cam rotates so that a portion extends outward from the latch mechanism and another portion releases a spring tab to engage and hold the latch bolt in the retracted position.  When the window is closed, the outwardly extending portion of the trigger cam contacts the meeting rail of the other sash, causing the trigger cam to rotate in the opposite direction and releasing the latch bolt.
