The rotor cap is constructed to function as an exhausting fan by puncturing a plurality of fan wings aligned radially and forming a plurality of fan vents thereon.

Abstract: The throttle of an engine in an engine driven generator system operating under an intermittently heavy load, as in supplying current to a welder, is controlled such that successive control signals sent to a throttle actuator for adjusting the engine throttle position are inhibited until at least a predetermined time has elapsed since the last preceding adjustment to the throttle. This procedure ensures that, as to each incremental adjustment to the throttle, the engine has sufficient time to respond, thereby preventing over-speeding or stalling the engine. The throttle actuator may be a stepper motor which is stepped by throttle position change signals from a processor which monitors engine speed and generator load to determine whether the throttle should be adjusted and, if so, in which direct. Alternatively, the throttle actuator may be a solenoid pulling against a spring in accordance with the average current through the solenoid coil.

Abstract: A portable generator includes a metal shroud surrounding at least a crankcase and a cylinder block of an engine. The engine is directly mounted to the shroud. The shroud forms an effective radiating element and gives an additional heat-radiating surface to the engine, thereby increasing the heat radiation capacity of the engine. Heat generated from the engine while running can, therefore, be radiated efficiently. The shroud is mounted within a sound insulating case, so that the portable generator has a double sound-insulating structure. The noise-proofing property of the portable generator is, therefore, very high.

Abstract: A portable generator comprises a shroud for covering at least a crankcase and a cylinder block of an engine thereof. The shroud is formed of split halves. The engine is fixed to the shroud having its upper part connected to a carrying handle of a sound insulating case. As a result, the load of the engine is applied to the carrying handle through the shroud when the portable generator is lifted up with a hand. It is thus not necessary to increase rigidity of the case, thereby enabling lightening of the case. The generator arrangement also provides an improved soundproof effect since the engine, a source of noise, is covered with the shroud and the sound insulating case.

Abstract: A method and device for generating an electric current and power from the earth's electric field. The electric current is generated by providing a thermoemissive material at some distance above the earth's surface, connecting the thermoemissive material to the earth's surface with a conductor (e.g., wire) such that a conductive path is established between the thermoemissive material and the earth's surface through the conductor, and heating the thermoemissive material to cause it to emit electrons into the surrounding air, thereby drawing replacement electrons from the earth's surface through the conductor to the thermoemissive material. One way to produce power in the above setting is by installing a D.C. electric motor or other electrical device along the said conductive pathway.
