Patent CA-2458124-C (CA)
Title: A power transmission mechanism, a fluid-driven impactor and its use
Inventor: TAO XINGHUA
IPC: E21B4/00
Filed: 2003-01-14
Granted: 2011-03-08
Abstract: The invention discloses a fluid driven impactor, a power transmission mechanism for the impactor and the use of the impactor. In the prior art, the working life of the impactor is short, since a rubber primary seal and an upper fluid-diverging lid for the fluid-driven impactor are both liable to erosion and the efficiency in transmitting power is low due to the complexity of the power transmission mechanism. In order to increase the drilling speed and/or extend the life of the impactor, the side cavity passage is formed in such a way that the inner wall of the outer pipe is isolated from the side cavity passage in a watertight manner without the use of the rubber primary seal. The loss in transmitting power is minimized by integrating the anvil of the power transmission mechanism and the lower joint.  The problem of abrasion of the fluid-diverging hole is overcome and the nozzle can be used with different fluid flow by mounting a replaceable nozzle in the upper fluid-diverging lid, the nozzle selected from a series of nozzles with various inner diameters and made of a material more wearable than the material for diverging lid the upper fluid.

Title: Medical device having releasable retainer
Inventor: CAIZZA RICHARD J
IPC: A61M5/158
Filed: 2004-04-23
Granted: 2012-08-07
Abstract: A medical device having a releasable retaining includes needle cannula connected to a hub having an open proximal end with a frusto-conically shaped cavity therein. The cavity is part of a passageway through the hub which is in fluid communication with the lumen of the needle cannula. A retaining element is releasably connected to the hub. The hub includes an aperture and at least one protuberance projecting into the aperture for engaging the frusto-conically shaped tip of a fluid delivery device. The protuberance is shaped to offer less resistance to hub movement in a direction of engagement than in a direction of disengagement with the tip. The retaining element is connected to the hub so that when the hub is engaged to the tip, the force required to disengage the retaining clement from the tip is greater than the force required to disengage the retaining element from the hub.

Abstract: A hoof trimming stall has a front gate having two pivotally mounted spaced- apart doors for swinging inwardly and outwardly. The doors are movable between a catching position in which the doors point inwardly for receiving a head of the animal entering the stall, a closed position for holding the animal in the stall with the neck of the animal caught in a gap between the doors, and an open position in which the doors point outwardly for permitting the animal to exit. A door lock/release mechanism has a slider arm movable forward and backward, a hydraulic cylinder for moving the slider arm forward and backward, a rear catcher mounted on the slider arm for preventing the doors from moving from the closed position to the catching position, a front catcher mounted on the slider arm for preventing the doors from being opened by the animal when the doors are in the closed position, and a release mechanism for permitting the doors to move from the open position to the catching position. An automatic reset mechanism automatically resets the doors and door/lock release mechanism. The reset mechanism has a sensor for signaling the hydraulic cylinder to move the slider arm backwards when the doors are in the open position and a spring for biasing the doors from the open position to the catching position.
