Abstract: EMPTY AND LOAD APPARATUS FOR RAILROAD CARS          Abstract of the Disclosure An empty and load air brake control apparatus for railroad freight cars, for applying full braking forces to the car wheels when the car is riding loaded, but for applying reduced braking forces to the car wheels that are at appropriate force levels when the car rides empty, in which in addition to the conventional brake pipe, AB or ABD control valve, the auxiliary and emergency reservors, the brake cylinder, and the retaining valve, are included a special load sensing device and a modulating valve for supplying full braking air pressures to the brake cylinder when the car rides loaded and reduced braking air pressures to the brake cylinder when the car rides empty.  The components of the apparatus are arranged and connected so that the load sensing device controls the operation of the modulating valve to supply the braking air to the brake cylinder that is appropriate for either loaded or empty braking, while providing for full braking air release at the retaining valve to the exclusion of the load sensing device, even when rock and roll are occasioned.         The arrangement is such that once the control apparatus is set to provide for the appropriate car braking, as sensed by the load sensing device, no amount of rock and roll can change the setting to loaded car braking where the car is riding empty or vice versa.

Title: Starting system for chopper controlled motor- commutated thyristor inverter
Inventor: STUDTMANN GEORGE H
IPC: H02P25/02

Granted: 1986-06-24
Abstract: STARTING SYSTEM FOR CHOPPER CONTROLLED MOTOR-COMMUTATED THYRISTOR INVERTER          ABSTRACT     If the thyristor switching devices of a chopper controlled  inverter  are  normally  motor-commutated during running operation, a starting system is needed to initially rotate the motor fast enough to develop a sufficient back EMF in the motor for motor commutation to occur.  This is achieved by regulating the operation of the chopper (16) to produce bus current pulses and by gating the thyristors (31-36) on in predetermined sets and in a prescribed sequence to current pulse energize the motor (41) to effect step-by-step rotation thereof, namely to crank or turn the motor one step at a time. After a set of conducting thryistors have supplied a bus current pulse to the motor, the reactive energy that builds up and becomes locked or stored in the induc-tances (such as the motor inductance), through which the motor current flows, must be dissipated in order to commutate the conducting thyristors off and reduce the motor current to zero before the next set of thyristors are turned on.   The required energy dissipation is accomplished by a circuit path which is effective during the intervals between the bus current pulses from the chopper.   A d-c voltage source, which may comprise a resistor (53) and a parallel connected capacitor (54), in the  circuit path  causes the reactive energy to be rapidily absorbed, thereby minimizing the decay time of the motor current to zero at the termination of each current pulse to permit faster turn on of the next set of thyristors and consequently faster starting.   Once the motor has reached a speed sufficiently high to permit motor commutation to occur, an SCR is gated on to by-pass the d-c voltage source and provide a low loss free-wheeling path for reactive energy during running operation of the system.
