摘要： A device is disclosed which maintains the preset position of a reciprocating fluid servomotor. The device includes a spool valve with the spool connected to the servomotor piston rod. Any drifting of the servomotor piston causes the spool to open a port directing pressure fluid to the servomotor to return the piston to its preselected position.

摘要： A soft-plugging control for a DC traction motor has a speed rheostat which regulates the duty cycle of variable width pulses applied by a power switch from a battery to the motor armature, means for algebraically summing the voltage across the power switch and the armature and means for decreasing the repetition rate of the pulses when said algebraic sum decreases below a predetermined magnitude as the armature voltage decays when said armature reverses direction.

摘要： A split casing pump is provided with a bracket which pivotally supports a lifting bar. The casing half which is desired to be removed is attached to a hanger which rolls on the lift bar. After the casing half is released from the stationary portion of the pump, it is swung out of the way on the bar so that the wearing parts of the pump can be replaced. For reassembly, the removed casing half is rotated back to its original position; and because the hanger can be rolled on the lift bar, it can be eased into proper bolting position.

摘要： A high voltage circuit breaker assembly adapted to reduce voltage surges which occur on prestriking of the switch during the closing stroke, such as when switching a capacitor bank onto a high voltage distribution line. The breaker assembly includes a first and a second breaker connected in parallel paths. Each breaker may be a vacuum interrupter. An operating mechanism causes the first breaker to close in series with a resistor during the closing stroke of the operating mechanism and during a later phase of the closing operation the operating mechanism causes closing of the second breaker to bypass the resistor. The operating mechanism includes means for maintaining the first breaker which is in series with the resistor open during the opening operation of the circuit breaker assembly, whereby to insure that the resistor is not in circuit during the opening operation so that the circuit is opened by the second breaker.

摘要： A fluid blast type electric circuit interrupter comprises a tank at ground potential containing compressed fluid (air). First and second hollow insulating columns are mounted on said tank in spaced apart relationship. The first insulating column supports six transversely arranged insulating housings and a pair of separable circuit interrupter contacts are located in each housing. The second insulating column also supports six transversely arranged insulating housings. A pair of separable isolator contacts are located in each of the two upper and each of the two lower housings on the second insulating column. A pair of separable resistor control contacts are located in each of the two middle housings on the second insulating column. All pairs of contacts are connected in series. Each pair of resistor control contacts is shunted by a closing resistor. Fluid flow control valves are located in the tank and in the two insulating columns to effect opening and closing operations of the pair of contacts of the circuit interrupter. The control valves effect an opening operation by first opening the circuit interrupter contacts, subsequently opening the isolator contacts and the resistor control contacts simultaneously, and subsequently reclosing the circuit interrupter contacts. The control valves effect a closing operation by first closing the isolator contacts and subsequently closing the resistor control contacts.

摘要： Electrical circuit interrupting apparatus comprises a support at ground potential having three spaced apart upstanding rotatable insulators thereon. Disconnect switch means are supported between a first end column and a second center column and rotation of both of these columns effects operation of the disconnect switch. A puffer type circuit interrupter is connected in series with the disconnect switch and is supported between the second center column and a third end column and rotation of the latter column effects operation of the interrupter. The interrupter comprises a sealed housing comprising a hollow insulator and a hollow metallic portion containing an arc extinguishing gas and a hollow stationary contact and a solid movable contact are located within the insulated portion of the housing. A stationary cylinder with a piston therein is also located within the insulated portion of the housing. Operating means are located in the metallic portion of the housing and are responsive to rotation of the third end column and effects piston movement in one direction and compression of the gas in the cylinder. Subsequent to compression of the gas in the cylinder, contact separation occurs and gas is forced from the cylinder, through the arc established between the separating contacts, through the hollow stationary contact and back into the housing.

摘要： A vacuum circuit breaker comprises three vacuum circuit interrupters, each having a pair of separable contacts therein, which are opened and closed by an operating mechanism. The operating mechanism comprises a separate operating rod connected to the movable contact of each interrupter and each operating rod has an opening acceleration spring connected thereto. All operating rods are driven to contact closed position by a main piston which is disposed in a hydraulic cylinder. Hydraulic fluid is supplied to the cylinder under great pressure by a high-speed gear pump, which is driven by a DC series-wound high speed electric motor, through a small orifice (containing a one-way check valve) located in a valve piston in the cylinder. The valve piston, which is spring-loaded, effects closure of a relatively large dump port leading from the cylinder. The valve piston is moved to open the dump port when the main piston is mechanically moved against the fluid in the cylinder by all operating rods as they are driven to contact open position by their accelerating springs. Closing of the circuit breaker is accomplished by energizing a closing solenoid which releases a first latch which allows a spring loaded motor control switch to close momentarily. Closure of the motor control switch starts the pump motor and the pump supplies hydraulic fluid to drive the main piston (and all operating rods) to contact closed position. Such movement allows a second latch to reset and engage a lever connected to the main piston to lock the latter (and the operating rods and contacts) in closed position. Resetting of the second latch also opens the motor control switch to stop the pump motor. Opening of the circuit breaker is accomplished by energizing a trip solenoid which releases a third latch which allows the second latch to be disengaged from the lever under the action of the opening acceleration springs on the operating rods as the latter move to open position. Such movement of the operating rods causes movement of the main piston, opening of the valve piston, and rapid dumping of the hydraulic fluid from the cylinder.
