    • A nuclear power plant installation comprises a nuclear reactor that is disposed in an underground reactor room and connected to power generating equipment on the ground surface by pipes which pass between the underground reactor room and the ground surface. A plurality of underground cavities are disposed above the underground reactor room, each of said cavities comprising steel bridgework that defines the sides and tops of the cavity and an unreinforced concrete floor which supports a mass of particulate shielding material within the cavity. An explosive charge embedded within each such mass may be detonated in the event of a malfunction of the reactor to fracture the floor structure in the cavity if the floor has not been fractured by the reactor malfunction, thereby to cause tons of mixed sand and boron powder to fall from said cavities into the reactor room and bury the malfunctioning reactor within a few seconds after the explosion. The installation also includes one or more underground personnel rooms which are connected to the underground reactor room by horizontal tunnels that contain normally open doors which are automatically closed in the event of an explosion in the reactor room.

    • An energy economizing AC power control system for energizing an induction motor comprises a sine wave power source which is connected via a triac to the motor, and a control circuit which controls the conduction of the triac as a function of the load on the motor to provide the motor with short bursts of energy. The control circuit includes a field effect transistor having a gate electrode which is energized by a train of sawtooth shaped control signals having a repetition rate which is twice the frequency of the power source, and DC bias potential is also applied to the gate electrode with the magnitude of the DC bias potential being varied with variations in the current flowing through the motor stator winding. The field effect transistor is rendered conductive during the sawtooth excursion of each of the control signals, at a time subsequent to the commencement of each sawtooth signal, which is jointly dependent on the instantaneous magnitude of the rising excursion of each sawtooth signal and the magnitude of the DC bias potential. The field effect transistor generates a pulse during each sawtooth excursion, at a time following commencement of the sawtooth excursion which is accordingly dependent on the load on the motor, and each such pulse is used to determine the time at which the triac commences conduction during each half wave of energy from the sine wave power source.

    • A direct current motor comprises a stator having a plurality of coils connected in series with one another located around a circle in a closed loop configuration, with the junctions between adjacent pairs of coils being in turn connected to diametrically opposed ones of said junctions in said closed loop configuration. A plurality of pairs of oppositely poled silicon controlled rectifiers are connected respectively to the junctions of different adjacent pairs of the coils for conducting current from a DC source into and out of the junctions. A wound rotor energized by the DC source drives a distributor which is arranged to energize the gate electrodes of different ones of the silicon controlled rectifiers in sequence so as to produce a plurality of stator poles which, at any instant of time, are angularly displaced from the rotor poles, and which stator poles shift in position about the closed loop coil configuration with rotation of the rotor. The rotor further includes a centrifugal switch arrangement operative to achieve one mode of operation when the motor is starting and a different mode of operation when the motor is running. In one form of the invention, the stator coil junctions are energized from the DC source through brushes associated with a commutator driven by the rotor in the starting mode of operation, and the brushes are lifted from the commutator and the silicon controlled rectifiers are controlled by the distributor when the motor shifts into its running mode of operation. In a further embodiment of the invention, the commutator is eliminated and the DC supply is rapidly turned on and off during the starting mode of operation.
