| 20110175425 | EMERGENCY LOCKING RETRACTOR - The present disclosure describes a dual mode emergency locking retractor (ELR) employing a mechanical strap acceleration sensing and locking mechanism in conjunction with an omni-directional housing acceleration sensing and strap locking system. The ELR utilizes a locking means responsive to the strap payout acceleration rate once a threshold rate of acceleration has been exceeded. The locking means terminates shaft rotation with a locking force which is proportional to the strap payout acceleration rate. | 07-21-2011 |
| 20110121977 | PNEUMATIC FIRE DETECTOR - A pneumatic fire detector is disclosed having a switch module comprising a manifold operatively connected to a sensor tube, the switch module incorporating respective forming tubes for applying a sufficient pressure to the outer surface of an installed diaphragm to deform it and thereafter the diaphragm is exposed to a pre-determined pressure through the manifold to deform the diaphragm outwards and into contact with a respective switch. | 05-26-2011 |
| 20090236205 | PNEUMATIC FIRE DETECTOR - A pneumatic fire detector is disclosed having a switch module comprising a manifold operatively connected to a sensor tube, the switch module incorporating respective forming tubes for applying a sufficient pressure first to the outer surface of an installed diaphragm and thereafter to a pre-determined pressure through the manifold to deform the diaphragm outwards and into contact with a respective switch. | 09-24-2009 |
| 20090173402 | SNUBBER VALVE - A snubber valve provides velocity- and/or position-dependent mechanical snubbing. The snubber comprises pressure sensing pins controlling the position of a float that changes the cross section of a fluid flow channel in the valve. In some embodiments, the pins sense their position in the valve, controlling the position of a float that changes the cross section of a fluid flow channel in the valve. Also provided are methods for snubbing, for example, an aircraft door. | 07-09-2009 |
