Title: Operating mechanism of a circuit breaker with a locking system disengageable on a short circuit
Inventor: NEBON JEAN-PIERRE
IPC: H01H33/42
Filed: 1997-02-05
Abstract: The invention relates to a mechanism for a multipole circuit breaker with high currents and high electrodynamic strength, comprising a toggle device associated to a trip hook and a switching bar, an opening ratchet cooperating with the hook to perform loading and tripping of the mechanism respectively in the locked or unlocked position of the ratchet.      The opening ratchet comprises disengageable actuating means causing self-unlocking of the catch in the presence of a short-circuit current exceeding a calibration threshold defined by flexible means, said self-unlocking being commanded from a mechanical reaction generated by the electrodynamic compensation effect and causing an ultra-fast rotation of the catch to unlock the opening ratchet before the tripping component operates.

Abstract: A guidewire retention device for use with a catheter or other medical device is disclosed herein. The guidewire retention device can be connected to a standard adapter at the proximal end of the catheter. It has an opening therein which can be placed in communication with the catheter lumen. This opening includes a large diameter portion and a small diameter portion and is preferably keyhole shaped. The large diameter portion allows a guidewire to easily pass therethrough while the small diameter portion does not. Thus, when a guidewire is located in the catheter lumen in the proper position, the guidewire can be fitted into the small diameter portion of the keyhole shaped opening to lock the guidewire with respect to the catheter. A raised icon on the guidewire retention device provides an indication to the clinician of how to use the guidewire retention device.
