Patent CA-2172658-A1 (CA)
Inventor: PETERSON RUDOLPH ANDREW JR
IPC: B60K28/04
Filed: 1996-03-26
Abstract: A simple operator presence override circuit is connected between available terminals on a PTO switch and a brake switch, and to the seat relay of the operator presence system. The override circuit permits continued operation of the engine under certain restricted conditions when the operator leaves the vehicle seat.  A blocking diode connects one side of the seat relay to ground via the brake switch and one set of terminals on the PTO switch.  With the PTO switch in the off condition and the vehicle braking system activated so the brake switch is closed, the seat relay remains activated to prevent operation of the ignition grounding circuit that otherwise would shut the engine down when the operator leaves his seat.  Switching the PTO switch on or deactivating the braking system without an operator on the seat will automatically open the seat relay so that the engine is killed.

Title: Perforating Gun Brake
Inventor: BLIMKE ROSS ARTHUR
IPC: E21B43/116
Filed: 1996-09-09
Abstract: A perforating gun brake includes a tubular housing, an annular piston and a mandrel.  A first end of the piston is telescopically received in an interior bore at a second end of the tubular housing.  The mandrel extends through an interior bore of the piston into the interior bore of the tubular housing.  An hydraulic fluid chamber is formed in the interior bore of the tubular housing.  A spring biases the piston toward a first end of the mandrel.  The movement of the piston along the mandrel is resisted by hydraulic fluid in the hydraulic fluid chamber.  An explosive charge is positioned on a first sealing assembly for the hydraulic chamber. Several gripping members are pivotally mounted to an exterior surface of the piston.  The gripping members are movable between a retracted position and a deployed position.  The gripping members are moved to the deployed position by a deploying collar that is released in response to pressure exerted upon detonation of the perforating gun.   The deploying collar holds the gripping members  in the deployed position until the first sealing assembly is removed by detonation of the charge,  thereby allowing hydraulic fluid to escape from the hydraulic chamber. As the hydraulic chamber is emptied of hydraulic fluid the piston moves along the mandrel.  The movement of the piston along the mandrel moves the gripping members away from the deploying collar allowing the gripping members to return to the retracted position.

Title: Process for reforming hydrocarbon feedstocks over a sulfur sensitive catalyst
Inventor: INNES ROBERT A
IPC: B01J29/62
Filed: 1995-06-21
Abstract: Provided is a process for catalytically reforming a hydrocarbon feedstock using a highly sulfur sensitive catalyst. The process comprises contacting the hydrocarbon in a reaction zone, with the hydrocarbon feed and catalyst flowing in opposite directions. Once the catalyst has passed through the reaction zone, it is then passed to a regeneration zone for regeneration. The process eliminates the need of passing the hydrocarbon feed through a sulfur sorber prior to entry into the reaction zone, as the spent catalyst which is leaving the reaction zone for regeneration acts as a sulfur sorber and removes the sulfur from the feed entering the reaction zone.
