Patent CA-2135985-A1 (CA)
Title: Relief valve with hydraulic fuse
Inventor: CHRISTENSEN NORMAN B
IPC: F15B20/00
Filed: 1994-11-16
Abstract: A relief valve for the hydraulic fuse minimizes the chance of a device such as a hydraulically powered lift de-vice from collapsing upon a break in a hydraulic input line to a cylinder powering the lift.   The relief valve com-prises a valve seat biased in a first direction by a rela-tively heavy spring and a hydraulic fuse biased away from the valve seat by a relatively light, second spring.  Upon a break occurring in the hydraulic input line, back pres-sure urges the fuse to seat against the valve seat, thus closing the valve.   Upon applying additional hydraulic pressure in the direction of the fuse, the valve seat dis-engages from the fuse, allowing hydraulic fluid to flow through the relief valve and thus allowing a piston in the hydraulic cylinder to retract so as to permit lowering of the lift device.

Abstract: An actuator and programmable amplifier is operative for use with an expanding plug gage head operated by an axially movable plunger having a tapered operating end and an opposite cross head end.  The cross head end of the plunger is releasably received and secured through a slot in a retracting lever which is pivotably mounted in the actuator/amplifier housing.   A compression spring normally urges the plunger to a fully extended position within the gage head. The retracting lever is actuatable for withdrawing the plunger from the gage head.   The actuator/amplifier device includes a transducer having a core which  is  coupled to the  crosshead end of  the plunger. The transducer is operative for measuring an axial position of the plunger within the gage head.  The programmable amplifier includes a memory for storing a plurality of sets of configuration data for a plurality of  different  gage  heads.    Each  of  the  sets  of configuration data includes a predetermined measuring dimension  of  the  gage  head,  and  a  predetermined amplification factor of the tapered operating end of the plunger of the gage head.  The amplifier further includes a key pad for inputting configuration data to the memory and for selecting one of the sets of configuration data from the memory.  A central processor is programmed to convert the sensed axial position of the plunger to a measured dimension according to the selected set of configuration data.  The measured dimension is output to a digital liquid crystal display.

Title: Fishing reel
Inventor: BOUTETTE GORDON DOUGLAS
IPC: A01K89/016
Filed: 1995-06-16
Abstract: A fishing reel includes a housing having an exterior surface, a circular end wall and a peripheral sidewall encircling the end wall thereby forming a generally cylindrical interior cavity. A spindle is provided having a first end and a second end. The first end is secured to the end wall and the second end extends axially into the interior cavity. The second end has attachment threads. A mounting bracket is secured to the exterior surface of the housing, whereby the housing is attachable to a fishing rod. A spool is provided having a first circular sidewall, a second circular sidewall and a concentrically aligned connective member. A spindle receiving bore extends through the spool from the first sidewall through the connective member to the second sidewall. The spool is mounted within the interior cavity of the housing by inserting the second circular sidewall into the interior cavity and extending the spindle through the spindle receiving bore. A handle is secured to the first circular sidewall of the spool, whereby the spool is manually rotatable in relation to the housing. A manually rotatable clamping member is threaded onto the attachment threads at the second end of the spindle. The clamping member exerts a clamping force upon the first circular sidewall of the spool, thereby providing resistance to the feeding out of line from the spool. The clamping force is adjustable by rotation of the clamping member. The advantage of the fishing reel is its silent operation.

Title: Method and apparatus for automatically stopping the process of filling a tank with a liquid under gas or vapour pressure
Inventor: FARKAS EDWARD JOEL
IPC: B65D90/48
Filed: 1996-01-12
Abstract: The invention described in the patent comprises a method and an apparatus for automatically stopping the process of filling of a tank or container with a liquid, where the liquid must always be maintained under a gas or vapour pressure which is typically different from atmospheric pressure. In the situations to which the invention is addressed, the tank is not to be filled completely with liquid. If the tank is correctly filled, there is at the end of the filling process a certain fraction of the total internal tank volume which is still occupied by gas or vapour. The invention provides for automatically stopping the fill at the correct point, through installation of one of several different devices within the tank, which create additional backpressure on the filling hose when the tank has become correctly filled, and through the operation of a microprocessor which receives signals from sensors located upstream of said filling hose, indicating that said increase in backpressure has occurred. In addition to automatically stopping the filling process at the correct point, the apparatus of the invention is fail-safe and self-monitoring and provides an immediate warning of any malfunction, such as an overfilled tank.

Abstract: The catheter includes a catheter hub at its proximal end having a radially extending wing. The needle is connected at its proximal end to a needle hub. The needle may have at least one notch therein. The needle hub defines a radially extending fin thereon. When the introducer needle is inserted through the catheter such that the distal tip of the needle extends beyond the distal tip of the catheter, the fin on the needle hub extends beyond the distal end of the wing on the catheter hub. This arrangement allows the distal tip of the needle to be retracted into the catheter with a simple proximal motion by the healthcare worker.
Patent CA-2168780-A1 (CA)
Title: Flossing equipment and method of operation
Inventor: KOSSAK MICHAEL
IPC: A61C17/16
Filed: 1994-08-03
Abstract: A dental flossing device is characterized by a flossing circuit comprising a floss supply spool and a take-up spool mounted to a housing containing a gear train assembly adapted to rotate the take-up spool in a winding direction. The floss feeds from the supply spool along a pair of prongs forming a forked extension of the handle and is stretched across the forked prongs and appropriately tensioned to be inserted into a user's mouth for flossing. To maintain hygiene, the take-up spool is mounted outside the housing.      In a manually operated embodiment, a manually depressible trigger projecting from the housing is operable to rotate the take-up spool with reverse rotation thereof being prevented with a ratchet mechanism. Release of the manually depressible trigger reversely rotates the supply spool through a short arcuate interval to remove slack and then locks the supply spool against unwinding rotation through gear teeth. In a preferred manually operated embodiment, first and second ratchet mechanisms are utilized to prevent reverse rotation of the supply and take-up spools while sufficiently tensioning the floss circuit. In other embodiments, the housing may be formed for mounting the flossing device as an attachment to a hand-held motorized toothbrush handle equipped with a motor from which projects an output shaft. Depending upon the model, the gear train assembly may be modified to convert longitudinal stroking motion of the shaft or oscillatory motion into uni-directional rotating motion to rotate the take-up spool in one direction only.
