Abstract: An emergency radio alerting and warning system comprising an FM transmitter having first and second encoding means, the first encoding means enabling the selection of all receivers in a given location, and the second encoder to enable broadcasting to be made to particular receivers in the selected location. The transmitter broadcasting signals with the encoded signals being followed by signals to cause audible alarms being sounded at the receivers so encoded, and then causing the messages being over loudspeakers at the selected receivers. The FM receivers being receptive but inactive until an encoded signal specific to that receiver being received, and then fully activating the receiver to sound an audible alarm to alert persons in the vicinity, and then to have the message broadcast. Timing means are present to terminate any message to the receiver after a given period unless extended by repetition of the coded signal by the transmitter.

Abstract: A compact, high efficiency non-interruptive motor generator power system for generating and supplying to a load A.C. of a substantially constant frequency and of a substantially constant voltage, the motor thereof being a synchronous A.C. motor energizable from a source of irregular and interruptible A.C. line power, the generator being capable of converting its rotational energy into the A.C. output for many seconds after interruption of the A.C. line power. The power system comprises a high efficiency, synchronous permanent magnet A.C. motor and an A.C. generator coupled to and driven by the motor. Both the motor and generator have a high rotational enertia common rotor wherein an outer cylindrical shell contains motor and generator rotor elements of high permeability soft magnetic material with a surface layer of magnetizable permanent magnetic material, and in each stator is an excitation coil, energizable with A.C.

Abstract: The present invention relates to a generator system connected to an external A.C. power source for supplying electrical A.C. power to a load for prolonged periods when the external electrical A.C. power source fails. The system comprises a main A.C. generator unit capable of generating an A.C. potential at a selected frequency and voltage for the load, and an auxiliary A.C. generator is connected to the main generator for generating A.C. at a high frequency. This high frequency A.C. is conveyed to a relatively small high speed motor and flywheel unit in a sealed chamber, which unit at full speed can store large amounts of rotational kinetic energy. The high speed motor has a stator armature with a power winding and an excitation coil, and a cooperating rotor of soft magnetic material having a cylindrical surface with a layer of magnetizable permanent magnet material thereon. When energized with the high frequency A.C., the power winding causes the rotor to rotate as a hysteresis motor.

The system comprises a main A.C. generator furnishing A.C. potential at a selected frequency and a selected voltage to the sensitive load, an auxiliary A.C. generator connected operatively thereto and a driving means for the generators energized with electricity from the external power supply source which is subject to outages and faults. The auxiliary generator generates A.C. potential at a much higher frequency than from the main A.C. generator and this higher frequency A.C. is supplied to a high speed A.C. induction motor and a flywheel unit in a sealed chamber, which unit can store large amounts of kinetic energy at full speed. Upon interruption of electricity from the utility or other external power source, the high speed A.C.

Phase shifting means are provided in the circuit leading to the excitation coil to enable the phase of the A.C. current being supplied thereto to be shifted with respect to the phases of the A.C.

Abstract: An internal combustion engine having a precombustion chamber connected to the cylinder by a venturi passage is supplied fuel through an opening in the venturi passage. Fuel is supplied to the precombustion chamber in an initial increment on the compression stroke so that the air and fuel in the precombustion chamber can be ignited at the end of the compression stroke and a stream of high pressure, hot gases returning through the venturi aspirate a second increment of fuel for completing combustion of the air in the cylinder. A bypass conduit from the precombustion chamber conveys gas under pressure to the fuel near the opening in the venturi to assist in ejecting said second increment of fuel into the hot gases in the venturi. A small cylinder and piston, or a diaphragm in the bypass conduit transmit pressure to the fuel without letting hot gases contact the fuel.
