Abstract: A quick coupler for joining two pipes that includes a male element adapted to be fitted into a female element and maintained in position by a latch forming a stop and opposing withdrawal of the male element. A movable safety member maintains the latch in a blocked position, under the force of pressure of fluid in the coupler, by the cooperation of two surfaces provided, one on the latch and one on the safety member, that are forced into engagement with one another. The safety member releases the latch when a residual pressure in the coupler drops to a safe level.

Abstract: Apparatus for testing an emergency valve in which a valve member (10) is movable by fluid-operated actuator (11) between a normal (open or closed) position and an emergency position (closed or open respectively). The apparatus comprises partial stroking means including means (32, 23, 22 to 13) for initiating emergency movement of the valve from its normal towards its emergency position, and means (13, 14) for returning it from a predetermined position intermediate the normal and emergency positions at its normal operating speed. The apparatus includes means for detecting the loss of the controlling electrical signal to the valve and a means (51) for detecting the correct operation of the valve and its associated operating components by measuring the pressure of fluid being released from or being applied to the actuator (11).

Abstract: A shared mesh protection scheme defines an associated protection path when a working connection is established. During the protection path definition, the corresponding protection path information is sent down to a switch card of network elements making up the protection path. Upon detection of the failure, the network elements using an overhead byte message will inform the routing source network element of the connection of the failure in the working path. The overhead bytes used are interrupt driven bytes located in the line and path overhead of network traffic. The routing source node of the connection will then send the corresponding overhead byte messages down the protection path to provide for protection path establishment according to the preloaded data located at the switch card. It should be noted that each connection can have a source and termination element which relates to the source from where the corresponding connection was set-up rather than the direction of the payload transmission.

Abstract: A portable pedal driven propulsion device for a small watercraft in which power from crank operated pedals is transmitted to a pivotally mounted gearbox on the outside of the watercraft adjacent the operator. A longitudinal drive shaft is connected, at one end, to the gear box and, at the other end, to a propeller so that the drive shaft and propeller can be moved selectively between a raised inoperative position and a lowered operative position.

Abstract: A quick connect coupling for removably connecting two pipes which comprises a male element adapted to fit into a female element along a principal axis of the coupling. The Female element includes at least one ramp for receiving a radial projection of the male element to lock these elements together. The ramp is formed in a ring freely rotatably mounted in the female element, and fixed in translation along the principal axis, while the projection is fixed with respect to the male element. The ramp forms a seat for locking the radial projection. Locking is obtained by essentially axial movements of the male and female elements with respect to one another.

Abstract: An installation for winding sheets of molding materials exiting a machine wherein at least two coil devices are provided at space locations horizontally with respect to an exit of the machine, and wherein the sheet material is directed to the coils by way of a horizontally movable carriage including a main frame and a secondary frame, which is adjustable horizontally relative to the main frame, and which carriage is movable horizontally to direct the sheet material to a selected one of the at least two coils.

Abstract: A humeral component, forming a first articulating surface, and an ulnar component forming a second articulating surface adapted to be disposed around a part of the first articulating surface and to pivot about its longitudinal axis. This ulnar component is provided with structure for mounting a locking element which forms a third articulating surface extending the second and adapted likewise to be disposed around a part of the first surface. These mounting structure comprise guiding structures adapted to cooperate with complementary structure provided on the locking element in order to guide this element in translation with respect to the ulnar component, up to a position where blocking structure provided respectively on the locking element and on the ulnar component may be employed to immobilize this element on this component, these blocking structure being able to be employed only in this position.

Abstract: Linearly actuated quick connect pipe couplings which include a male element and a female element adapted to fit into each other along a principal axis. One of the elements includes at least one ramp for receiving a radial projection mounted to the other element which locks the elements together by axial movement of the elements relative to one another. One of the ramp or the projection is formed with a ring mounted to rotate but is fixed in translation along the principal axis of one of the male or female elements. The ramp forms a first seat for locking the projection when the coupling is in a configuration to permit fluid passage and a second seat, offset axially with respect to the first seat, for locking the projection when the coupling is in a configuration to permit decompression of fluid within the coupling.
