Abstract: A reduction gear type D.C. starter motor for an internal combustion engine including a planetary type reduction gear system mounted in a front bracket at a faucet joint portion between it and a rear bracket, the rear bracket and the yoke being integrally formed.

Abstract: An electric generating system is provided and consists of an external power source, an expansion engine connected to the power source, a large generator electrically connected to output of the expansion engine, a housing having a well, a pair of bearings mounted to side walls of the well, a motor having a drive shaft, the motor mounted vertically at bottom of the well, electrically connected to output of the generator with the drive shaft rotatably mounted in the bearings having an end extending therefrom, a large bevel gear driven by the drive shaft of the motor, a plurality of small bevel gears, each small bevel gear radially aligned and driven by the large bevel gear and a plurality of small generators, each small generator having a driven shaft affixed to a small bevel gear and mounted to the housing around the well to produce 100 percent output of electrical power.

Abstract: A regulator system for both the Diesel and the electric portions of a Diesel electric locomotive allowing more reliable operation at all locomotive speeds. Said regulator has a regulator to regulate the electric power by varying the excitation (43) of the main generator by means of orders coming from a driver control (1, 8) which set a reference current level and (17) a voltage reference level (19) for the main generator and a Diesel engine gas oil reference level (18). These levels are compared with measurements of true corresponding values (24, 30, 27) and orders (43) for increasing or decreasing excitation are delivered so that the excitation of the main generator remains inside the scope delimited by the various reference levels and a Diesel power regulator which sends out orders to increase or decrease the gas oil injection in accordance with a predetermined Diesel engine speed/injection law and in comparison with the true measurements of the injection and of the Diesel engine speed.

Abstract: A power fail circuit provides protection for tape such as used in the tape transport apparatus of a video recorder in the event of a failure of the external power supply. The tape transport apparatus includes as a feature the provision of an electrical error signal used to govern drive motors to maintain substantially constant tape tension when the system is operating normally. After power failure occurs, the power fail circuit continues to respond to the error signal by coupling current from the drive motors to provide dynamic braking. Further, current taken from the drive motors selectively is coupled to an energy storage device operatively associated with the system power supply, to provide augmenting energy from the kinetic energy of the motors for continued control of the power fail circuit as the drive motors are caused to decelerate under control to stop.

Abstract: An apparatus for operating an AC powered elevator which connects an elevator controller to a capacitor for supplying DC power to an inverter when the AC power is interrupted while the cage of the elevator is running, thereby continuing to operate the elevator controller and the cage of the elevator to bring the cage to a floor and open the door of the cage to permit passengers within the cage to be evacuated. Circuitry is also provided to prevent damage to the inverter while supplying the AC power from the capacitor to the AC motor.

Abstract: A vibrating armature motor, which includes a voltage source, an armature, an electromagnet having at least one exciter coil disposed adjacent the armature, a spring for rotationally biasing the armature, a sensor element for sensing the rotational velocity of the armature and for generating a signal proportional to the sensed velocity, a variable duty cycle pulse generator for generating a stream of triggering pulses, the duty cycle of the triggering pulses being dependent upon the sensor signal, and an electronic switch for controlling the current flow from the voltage source through the exciter coil in response to the triggering pulses.
