A control system is disclosed for a high temperature gas cooled reactor power plant, wherein a steam source derives heat from the reactor coolant gas to generate superheated and reheated steam in respective superheater and reheater sections that are included in the steam source. Each of dual turbine-generators includes a high pressure turbine to pass superheated steam and an associated intermediate low pressure turbine to pass reheated steam. A first admission valve means is connected to govern ...

An internal combustion engine and a method of coating a combustion chamber wall surface therein comprising the steps of preheating the base metal forming the wall surface to at least 500.degree. F. and fusion bonding a base layer of nickel and aluminum to the preheated base metal for retarding conductive heat transfer through the wall surface. An intermediate layer comprising nickel, aluminum, and copper is applied over the base layer and an outer layer of copper for reflecting infrared heat is ...

A gasket construction comprising a carrier having a sponge rubber member about the periphery thereof and steel ferrules and rubber grommets situated at various positions in the carrier so as to connect oil and water passages from the cylinder head to the block.

A rotary engine of the oscillating rotor or "cat-and-mouse" type including a shaft with a pair of rotors each mounted for rotation with respect to the shaft and for oscillating rotation with respect to each other. The engine includes drive means having drive members reciprocable in response to oscillating rotation of the rotors with respect to each other, and means responsive to reciprocation of the drive members to cause rotation of the shaft.

The valve operator disclosed includes a housing constructed of substantially identical housing halves joined together at mating surfaces. Cylinder means is secured to the housing and bridges the housing halves.

A power source for an underwater tool comprising a hollow cylinder filled th a hygroscopic gas. At sea level the gas is maintained at atmospheric pressure so that when lowered to deep ocean depths, high pressure sea water will operate a tool connected thereto and then pass into the cylinder through a small orifice. The hygroscopic gas absorbs the water and maintains a constant low back pressure in the cylinder so that the power available remains constant as the cylinder fills.

A fluid actuator with improved end plate and tie rod construction to facilitate external removal of a rod bearing and rod seal cartridge. The cartridge is received in an external cavity in one end plate and is retained by a cover plate. The plates are secured by separate sets of nuts threaded on common tie rods that extend in nonthreaded engagement through aligned throughbores in the end plate and cover plate. The nuts that retain the end plate are recessed in counterbores in the end plate.

A pneumatic cylinder connected between an eccentric on a rock shaft and a structural support, for absorbing energy during one quarter of the cycle of the rock shaft during which it is decelerated, and for putting the absorbed energy back into the rock shaft during the next quarter cycle when it is accelerated. The pneumatic cylinder is preferably a double-acting one with a center port to accomplish the energy absorption and redelivery to the rock shaft, at both ends of the shaft rocking movement...

A cylinder separated into two opposed portions interconnected by an elongated gas passageway which is constantly heated at one end and constantly cooled at its opposite end. Gas is forced back and forth through the passageway by a free piston arranged within the cylinder portion between the heated passageway end and adjacent cylinder end and by a driven piston arranged in the opposite cylinder portion. The free piston is reciprocated by the pressure of the heated gas on one face and the pressure...

For use in connection with an implement, especially of the excavating and earth-working type, which has a rotatable part and a part normally held stationary during the working of the implement, a turntable which includes: a supporting member connectable to a stationary part, a plurality of antifriction bearing means supported by said supporting member along a circular path, a rotatable member forming a platform and being connectable to a rotatable part, fluid operable cylinder piston means havin...
