A power plant for generating electric power and pneumatic pressure includes an internal combustion engine, an electrical generator, and a compressor and pneumatic supply tanks. Both the electrical generator and the compressor are driven by the engine, however, the engine drive is so coupled and controlled that the engine drives the generator as its primary load, and the compressor as its secondary load and apportions the engine power between these units according to need. When the generator uses...

A compact portable power supply including an internal combustion engine that drives a generator and which engine is fueled by a pressurized source of gaseous fuel. The outer housing and control structure is configured in such a way that the source of gaseous fuel will always be oriented so that liquid fuel will not be delivered to the engine when the power supply is in use.

A portable heat transfer apparatus including a combustion device, a thermoelectric convertor for receiving the heat of the combustion device at its high temperature side, transferring the heat from its low temperature side to a heat exchanger, and generating electric power depending on the temperature difference between the high temperature side and low temperature side. A heat medium forced circulating device is driven by the power generated from the thermoelectric converter for transferring he...

A marine power distribution arrangement utilizes generators driven at standard or higher than normal speeds and/or having a number of poles to produce electric power at a standard 50/60 Hz frequency or substantially higher than the standard 50/60 Hz frequency, such as 400 Hz. Each generator is a multi-phase, multi-circuit generator supplying isolated outputs on a plurality of lines to a propulsion power converter having isolated inputs to provide variable frequency, variable voltage power to a s...

Engine-powered portable working apparatus (100) including a soundproof casing (4) for accommodatingly supporting therein a main unit (1) having an engine (10) and a rotary working machine (11) driven by the engine, and a carrying handle (6) provided on the soundproof casing. The soundproof casing (4) comprises a first casing half (2) and a second casing half (3) to be joined together along a predetermined mating plane (P). The first and second casing halves (2, 3) are, respectively, integrally f...

A generator set including an internal combustion engine which drives an alternator or generator to generate electricity. The engine and the generator are air cooled by air driven by a fan along two parallel air cooling circuits through the generator set. The components of the set are enclosed in a two-piece housing or enclosure having two openings, an air inlet and an air outlet.

A power system specifically adapted to provide DC power for powering a DC load at a remote site under severe environmental conditions, such as is found at remote gas pipeline locations. The power system includes a slow speed heat engine adapted to be powered by fuel, preferably taken directly from the gas pipeline, the supply of which is controlled by means of a pressure regulator. The engine is adapted to be directly coupled to an oversized, slow speed three-phase alternator so as to produce AC...

The present invention includes automatic lift-type power generation equipment unit A which is one of the equipment within the automatic lift-type mobile facility that is adapted to be loaded onto the rear of a carrying vehicle (a), comprising a power generation section 1A which is a component of said mobile facility, supplies electric power by generating said power, and includes cubicle 3A, prime mover equipment 4A, and electric power equipment 5A, and an automatic lifting-and-lowering section 2...

A low profile generator mount for large vehicles, such as tractor trailer combinations, utilizes the space below the door of the cab. The mount is an enclosure connected to the frame and housing a compact diesel engine and generator combination with the exterior of the mount capable of being in the form of steps for ingress into the cab, or formed to assimilate a conventional truck mounted storage box.

An improved mobile electric power generating system comprising a substantially enclosed trailer for housing a power plant, and improved methods for assembling the same are disclosed. The improved system includes means defining a modular utility frame for carrying various support components of the system. Such support components may include a fuel storage tank, a start-up energy storage tank, a radiator, and power plant support apparatus.
