Abstract:
There is provided an R-θ table apparatus which freely movies one table on a plane in the forward-and-rearward and leftward-and-rightward directions and in the rotational direction. The R-θ table apparatus changes a horizontal distance between a center line of a main axis of a driving apparatus and the action point by elevating an elevating base, and a table is moved to an arbitrary position without rotating along a guide member.
Abstract:
This invention is a piston in cylinder engine using water injection into a relative vacuum heated to steam by expanding in the cylinder and by an electric arc or other heat source. The resulting steam explosion applies a work force on the piston. The piston has jet nozzles uncovered at the end of its work stroke to jet the piston to help propel it during the return stroke and to form a vacuum in place of the usual compression stroke. The piston has a cover plate with tapered pins depending into jet nozzles through the piston to block the jet nozzles during the main work stroke.
Abstract:
An improved procedure for cold start-up of closed loop boiler set and Cheng cycle system wherein the venting step, the boiler swelling problem and blowdown step of the conventional start-up are eliminated by use of an external pressure source to increase the operating pressure in the evaporator section which minimizes premature phase change and accompanying volume increase.

Abstract:
An exemplary embodiment of the present disclosure provides an intake device including: an annular flow path which is formed in a circular housing; an inlet part which is installed at one side of the housing and guides an inflow of a fluid into the flow path; a outlet part which is installed at the other side of the housing and guides a discharge of the fluid which flows into the inlet part and passes through the flow path; a piston which is disposed in the flow path, and rotates along the flow path so as to compress the fluid introduced through the inlet part; and an opening and closing unit which is installed in the flow path between the inlet part and the outlet part, includes a plurality of opening and closing members, and elastic members which are installed between the plurality of opening and closing members and the flow path so as to support the plurality of opening and closing members, respectively, and opens and closes the flow path by pressing the piston, in which when the pressing of the piston is released, the plurality of opening and closing members closes the flow path by pressing force of the fluid which presses outer circumferential surfaces of the plurality of opening and closing members in a direction in which the flow path is closed, and by elastic force of the elastic member.
Abstract:
A hydraulic external heat source engine wherein energy is supplied to a working end space of the engine by direct application of pressurized and heated liquid working fluid to the piston within a cylinder. The power stroke utilizes expanded hot liquid as the primary pressure source. After fluid intake cut-off, some of the heated liquid spontaneously vaporizes, thereby continuing to drive the working piston. The exhaust liquid working fluid discharged from the cylinder is recycled to an external preheat exchanger for preheating cold compressed working fluid expelled from the pump end space of the engine. The majority of the vapor produced within the cylinder recondenses within the cylinder and is discharged as liquid. The small amount of vapor that is discharged from the cylinder is condensed in an expansion chamber in the preheat exchanger. The preheated fluid is heated to operating temperature and pressure in a primary heat exchanger before being recycled into the working end space. The cooled exhaust fluid in the preheat exchanger is passed through a cold reservoir exchanger for further cooling before introduction into the pump end space. The engine is large and is well suited to stationary applications using low-grade heat sources such as solar, geothermal, and waste heat to supply heat to primary heat exchanger.
Abstract:
An improved double-acting, nonexpansion, noncondensing, piston steam engine. A coiled tube flash boiler enclosed in an insulated fire chamber is located above and contiguous with the cylinder head of the steam engine. The base of the fire chamber has a cylindrical opening to enable the heat from the flames in the fire chamber to be transferred directly to the top cylinder head for enhanced heat transfer to the cylinder. Two parallel crank shafts, each having a spur gear fixed thereon which meshes with the spur gear fixed on the other, are mounted on pillow block support bearings. A "T" linkage interconnects the crank shafts and the piston of the steam engine. Two rotary valves are provided to control the flow of high temperature steam and spent steam to and from the cylinder.
