The two FMG units produce the bi-directional roll torque characteristic necessary to develop roll-dampening torques for the missile system roll control autopilot.

Abstract: This specification describes a completely new and different concept, method, mechanization, apparatus configuration and sequencing procedure for obtaining commercially useful energy and power, namely: the use of a gyroscope to generate output power from the earth's stored inertial rotational (flywheel) energy by fixing the housing of the gyroscope to the earth and using the rotation of the earth relative to the gyroscope's spatially stable rotor/gimbal assembly to rotate the input shaft(s) of a power transducer(s). This provides a power-output stroke over a near 180.degree. precession excursion (near pole-to-pole alignment) until the rotor spin axis of the gyroscope is nearly aligned with the polar axis of the earth. Re-precession torques are then created on the inner gimbal within the gyroscope to re-orient the rotor spin axis vector direction by re-precessing the rotor spin by somewhat more than 180.degree.

Abstract: Proximity switches and circumferentially movable stator windings allow a motor-generator to simultaneously sense and switch from a synchronous motor position to a synchronous generator position. This mechanism replaces the conventional separate sensing and switching of motor-generator functions. Automatic rotational repositioning of the stator maintains constant voltage and prevents the generation of transient voltages or harmonics. The stator flux leads the rotor magnetic flux slightly in an import power or motor position, creating a torque on the rotor and a counter torque on the stator reacted by the fixed casing of the apparatus. As the stator field weakens due to a failure of the normal power supply, the counter torque also weakens and the stator windings is biased to begin to turn with the rotor until the rotor and stator fields are in step, i.e., when virtually no current is generated or consumed or until a full export power or generator position is reached.

If the gas cock is used to stop the engine, the engine will continue to run until fuel remaining in the fuel line has been expended, and then safely and automatically shut-down.

Abstract: There is disclosed an apparatus for controlling the rotational speed of a Stirling engine in such a way that effective use is made of dump power produced when the speed of the engine is maintained constant. The apparatus comprises a tank in which a working medium is stored, a first valve mechanism, a second valve mechanism, a dynamo for producing alternating current during operation of the engine, a load to which the alternating current is applied, an accessary receiving the alternating current via a distributor, and a control unit.

When the engine speed increases, the resulting increase in the electric power is consumed for the accessary such as a cooling fan or a battery that powers the starter.

Abstract: A safe and arm device with a thermomagnetic generator sharing a tubular sed shaft with a turbine. Weapon propellant exhaust gas enters the shaft and heats thermomagnets in the generator causing their magnetism to be produced and flux lines to flow from rotor to stator. The gas moves translationally through the shaft and into the turbine. The gas leaving the turbine rotationally is discharged into a radial exhaust tube. A plug in the tube must be removed to permit gas exhaust from the turbine. Only then can the turbine and connected generator rotate causing the thermomagnetically produced flux lines of the rotor to be cut by the stator resulting in an induced voltage out of the generator.

Abstract: A cogeneration system is disclosed using a Stirling cycle engine in which the waste heat from the engine and a generator driven by the engine is used for space heating or producing hot water and the generator used to produce electricity. A Stirling engine has numerous advantages over a reciprocating internal combustion engine in cogeneration systems in that the Stirling engine has a longer life, less maintenance cost, less noise and vibration and fewer emissions. With cogeneration, the added energy and fuel required over and above that required to produce a comparable amount of heat allowed to produce the same amount of heat with a conventional furnace or boiler is often less than the amount of electric energy produced from the system thereby resulting in a efficiency greater than 100% in the production of electricity.

In the normal-power mode of operation, the vehicle voltage regulator sees the full voltage generated by the vehicle alternator. In the high-power mode of operation, the vehicle voltage regulator sees only a reduced portion of the full voltage generated by the vehicle alternator.

Abstract: A welder's helmet including a panel of solar cells responsive to light generated by a welding operation to drive a fan incorporated in the helmet structure. The solar cells are mounted on the helmet above the viewing window and the fan is mounted in front of the mask below the viewing window.

As air is exhausted from the inside of the helmet outward by the fan, fresh air is drawn in around the sides to replace that which is being exhausted to cool the welder and prevent ingestion of fumes and vapors.

Abstract: An intermitently operable non-fuel-consuming power generator, such as a photovoltaic array or a wind generator, is connected through a control circuit to a battery for charging the same and supplying current to a time-wise substantially constant electrical load. An electrical generator, connected to an intermitently operable prime mover, charges the battery and supplies current to the electrical load when the prime mover is operated.

The scheme uses a set of massive underground spinning wheels, each wheel being fitted with a mechanism to receive and transmit gravitational torque pulses from a passing vehicle to keep the wheels in motion. The mechanism used to apply the torque pulses to the spinning wheels consists of a stepping board, a hollow cylindrical rod disposed vertically and a shoe attached to the lower end of the vertical rod by a hinge with the upper end of the rod protruding above the ground surface. A steel linkage connecting the stepping board and the lower part of the shoe is used for initial positioning of the shoe.
