Title: Spark erosion machining apparatus
Inventor: SCHNEIDER RUDOLF
IPC: B23Q3/155
Filed: 1988-06-30
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a spark erosion machining apparatus com-prising an electrode changing mechanism. The apparatus compris-es a tub intended to receive the dielectric liquid and having a front wall which can be opened like a door. A frame displace-able with regard to its height position is fixed at the inner surface of the door-like front wall. Two pairs of levers are pivotally mounted on the frame. The free ends of the levers comprise a transverse beam with a plurality of perpendicularly protruding electrode supporting members. The transverse beams with the electrode supporting members can be pivoted from a rest position where they are near to the front wall of the tub into an operating position where the electrode support members are in an essentially central portion of the tub. The electrode changing mechanism is very well suited for the modification of existing spark erosion machining apparatus.

Patent CA-1289892-C (CA)
Inventor: ELLERS CLARENCE W
IPC: B60L50/15
Filed: 1988-11-15
Granted: 1991-10-01
Abstract: Clarence W. Ellers - Inventor Docket No. 3524 AUTOMATIC SERIES/PARALLEL FAIL SAFE  HYBRID ELECTRIC/ICE VEHICLE DRIVE SYSTEM WITH FULLTIME ICE CRUISE CONTROL            ABSTRACT OF THE DISCLOSURE  Presented is a hybrid vehicle selectively driven by either an electric motor or an internal combustion engine acting independently of the other, or by both electric motor and internal combustion engine acting in unison.  The vehicle is initially propelled by the electric motor working through a four speed transmission to drive a first set of wheels, and speed control is achieved by shifting of the transmission, either manually or automatically, while in electric drive alone.  When the vehicle achieves a predetermined cruising speed while being propelled by the electric motor, a speed sensor activates the application of a less than maximum voltage to a magnetically actuated variable torque converter interposed between the second set of wheels, which are rotating on the roadway, and the internal combustion engine.  The momentum of the vehicle, acting through the second set of wheels, actuates the variable torque converter to "crank" the internal combustion engine to start it. Slippage in the torque converter because of the less than maximum voltage applied to it permits progressive engagement between the torque converter and the internal combustion engine.  When the engine starts, it drives a generator that then applies full voltage to the torque converter, resulting in a direct connection between the internal combustion engine, the torque converter and the second set of wheels, with the internal combustion engine running at a preset or predetermined constant speed.  As soon as the internal combustion engine starts and is running at constant speed, the electric motor is deenergized as a driving unit.  The electric motor may be re-established as a driving unit by depressing the accelerator pedal to the floor, thus energizing the electric motor, which now functions to assist the internal combustion engine in propelling the vehicle.  Releasing the accelerator pedal while the vehicle is moving at faster than the preset cruising speed results in the electric engine again being deenergized.  On the other hand, at speeds below the preset cruising speed, all that is required to shut down the internal combustion engine is to tap the brake pedal, whereupon the vehicle remains propelled only by the electric motor.
