Patent CA-2051065-A1 (CA)
Inventor: BRIGHENTI DONALD D
IPC: G08B26/00
Filed: 1991-09-10
Abstract: A method and apparatus multiplexing multiple alarm and head type values in a peripheral fire alarm device includes a head component for sensing the presence or absence of smoke or heat and a base component for communicating with the central panel. A communication interface between the base and head components with no more than three connectors for multiplexing the values between the head component and the base component.      The control panel stores algorithms particular to each type of head which may be used to determine if an alarm condition exists. Using data received from the peripheral fire alarm device, the control determines which type of head component is currently installed at the base component and selects the correct algorithm.

Title: Apparatus and method for driving a large traveling crane
Inventor: THORSEN GEORGE
IPC: B66C9/16
Filed: 1991-09-30
Abstract: Abstract of the Disclosure A drive for a traveling bridge crane including a bridge having a width spanning two parallel spaced apart rails and opposite ends located at one of the rails.  A first pair of wheels comprising first and second wheels are respectively mounted at the opposite ends of the bridge and each of the first and second wheels engage a different one of the rails. A second pair of wheels comprising third and fourth wheels are also mounted at the opposite ends of the bridge and each engage a different one of the rails.  The crane travels along the rails on the first and second pair of wheels in a position generally parallel to the rails.  The crane is subject to unbalanced wheel rotating forces causing the crane to frequently attempt to skew.  First and second drive mechanisms are respectively connected to the first and second wheels of the first pair of wheels for rotating the first and second wheels independently of each other.  A third drive mechanism is connected to both of the third and fourth wheels.  The third drive mechanism applies the unbalanced wheel rotating forces on the crane bridge equally to the third and fourth wheels to minimize skew movement of the third and fourth wheels and the independently driven first and second wheels.  Minimizing of skew by the third drive mechanism maintains traction at each of the first, second, third and fourth wheels.
Patent CA-2054907-A1 (CA)
IPC: F16D7/06
Filed: 1991-11-04
Abstract: An adjustable, precision overload clutch device is disclosed as comprising a rotating driving member drivingly coupled by spring-urged detent plunger members to a driven member, in which bearings are provided for journalably mounting the head of each plunger member to the driving member, and spring adjusting members which permit pre-loading by the spring of each detent plunger and associated bearings.  This combination allows the overload clutch to achieve a high locational accuracy upon each resetting after clearance of an obstruction.  Elastomeric springs are preferably used for the detent plunger springs, so that by use of the adjusting member, the overload torque range for the precision overload clutch can be substantially adjusted (within limits) as desired for a given application.  The clutch also includes structure to make it moisture resistant, including when coupled to an intermittent drive unit, such as a motor-driven indexer, for example.

Title: Instrument for ligation and castration
Inventor: WOODS JOHN B
IPC: A61D1/06
Filed: 1993-02-23
Abstract: Abstract of the Disclosure An instrument for castration by ligating and severing blood and seminal vessels.  A pistol-shaped tool comprises a hollow body forming a barrel and a hand grip.  A yoke pivotally mounted in the cavity of the grip is pivotally connected to a trigger, ligating means and severing means.  The vessel to be ligated and severed is positioned in a slotted area at the muzzle of the barrel.  The initial pulling of the trigger toward the grip causes blade guards connected to the severing means to surround the vessel or vessels.          Further movement of the trigger toward the grip actuates the ligating means to push a ligature from a ligature container and around the vessels.   The ligature is forced through ligature compressors which press the locking ligature onto the vessels.          Final movement of the trigger toward the grip moves the severing means to force a blade through the vessels.
