Patent CA-2071281-A1 (CA)
Title: Incremental dispensing device
Inventor: ANDERSON J EDWARD C
IPC: B05C17/015
Filed: 1992-06-15
Abstract: ABSTRACT      A fluid actuated dispensing device having a valve assembly and an actuating piston provides incremental movement of a drive piston within a tube holder.  The valve assembly includes a trigger piston and a valve ball biased into engagement with a valve seat.   A trigger is adapted to engage the trigger piston and urge the valve ball away from its seat to allow fluid to enter an actuating chamber.   The increase in fluid pressure within the chamber drives an actuating piston from an initial position to an extended position in the chamber.   The actuating piston is adapted to drive a washer off-center against a push rod during the stroke of the actuating piston.  The washer cocks and grabs the push rod and urges the rod forwardly within the tube holder.   A drive piston connected to the push rod is thereby driven forward within the tube holder for the full stroke of the actuating piston.  When the trigger is released,  the fluid in the actuating chamber  is exhausted through a passage in the trigger piston, which thereby reduces the pressure in the actuating chamber. The reduced pressure in the chamber allows a spring to uncock the washer and bias the washer and the actuating piston back into their initial positions, which provides for incremental movement of the push rod, and hence the drive piston.   360/21332ADA.20A

Patent CA-2072896-A1 (CA)
Inventor: BEURET PIERRE
IPC: C21D9/00
Filed: 1992-07-02
Abstract: The charging trolley (25) brings the charge and deposits it on the plug (10) of the oven (1). 
<??>The introduction of the charge into the oven (1) and its closure are performed by the action of the lift (12) which comes down again after the treatment to an intermediate position, from which the oven (1) can be moved horizontally, the lower belt (4) pushing the base grid of the charge onto the lid (17) and the tray (22) of the lift (18) placed in upper position. The lid (17) ensures that the oven opening is sealed against the gases for protecting the charge. 
<??>This lift makes it possible to introduce the charge into the quenching tank and then to return it into a draining position and to deposit it on the discharging trolley (38) travelling on the line (36, 37).

Title: Parametric Control Device
Inventor: BOCK OTMAR
IPC: B25J9/16
Filed: 1992-10-27
Abstract: An adaptive control system for mechanical and dynamic systems being transferred from an initial to a desired final state by control devices. The control system comprises an adaptive contraller (e. g. in the form of an artificial neural network) for providing scaling parameters p, from inputs to the controller of coordinates for desired final and initial states, to a function generator which provides prototypical time functions scaled by the above parameters, those signals being provided directly via connections to the control devices which generate the required control signals. The adaptive control system may be used for a robotic manipulator having a number of rigid links interconnected by joints, the links being moveable by actuators. The manipulator's Kinematics and Dynamics, including joint interaction effects, are taken into account by this adaptive control system and it controls a manipulator's movements without the need for any real-time feedback circuity or any explicit calculations of inverse kinematics or inverse dynamics.

Abstract: A system for the transport of high solids materials such as concrete includes a positive displacement pump, a pipeline connected to the pump and a valve in the pipeline located downstream from the pump for preventing material flow through the pipeline when the valve is in a closed position. The valve is closed at the end of each pumping stroke to prevent material flow through the pipeline. The pressure of material on the pump side of the valve is sensed. During a subsequent pumping stroke, the valve is opened when sufficient pressure exists on the pump side of the valve to ensure that material will flow in a positive direction through the pipeline.
