Abstract: A building structure encloses a gaseous mixture of air and a combustible fuel. Air is obtained from the atmosphere, and the gaseous fuel is obtained from natural evolution and diffusion processes associated with rotting of materials, as from landfills, and gaseous digestion products from livestock, etc. A process control system is engaged for drawing off the gaseous mixture, at a selected air-fuel ratio, from the structure. The selected gaseous mixture is drawn from the building, through a compressor and then a pre-heater, into a catalytic combustor where the mixture is burned and directed into a turbine for producing work. This work is preferably converted into electricity by a generator driven by the turbine. A process controller senses process variables such as temperature, pressure, latent heat of fusion, etc. so as to assure that combustion cannot occur prematurely, but does occur most efficiently in the catalytic combustor. Process heat is exchanged for preheating the mixture to be burned.

Abstract: A vacuum pump has a housing enclosing a pump mechanism. The pump mechanism has an electrical motor enclosed in a motor chamber. Air pumped by the pump mechanism is exhausted into the enclosed motor chamber to cool the motor and then exhausted out of the motor chamber and pump housing. The relatively higher density air passing through the motor chamber and housing improves convective cooling of the pump motor.

Abstract: A liquid discharge head is provided having a heating member for generating thermal energy to create a bubble in liquid, a discharge port adapted to discharge the liquid, and a liquid flow path communicated with the discharge port having a bubble generating area for enabling the liquid to create the bubble. A moveable member is arranged in the bubble generating area to be displaced along with the development of the bubble. A regulating portion regulates the displacement of the moveable member within a desired range, and by means of energy at the time of bubble creation, the liquid being discharged from the discharge port. The regulating portion is arranged to face the bubble generating area in the liquid flow path. A support member is directly connected to the moveable member. The bubble development causes the moveable member and the regulating portion to be in contact forming an essentially closed space with the exception of the discharge port.

This water flows through nozzles X2 for washing thereof.

Abstract: An electromagnetic diaphragm pump has two compression sections operated by an AC. Each of the compression sections comprises an oscillator disposed within a housing and holding a permanent magnet, a pair of diaphragms each having a peripheral portion fixed to the housing and a central portion fixed to an end portion of the oscillator, a pair of field cores sandwiching the oscillator and having magnetic poles displaced relative to the permanent magnet by a predetermined amount, coils for producing magnetic fluxes at the field cores, and compression chambers opposed to end portions of the oscillator, one of walls of each of the compression chambers being formed by an associated one of the diaphragms. The field cores have the magnetic poles magnetized by the AC supplied to the coils, whereby the permanent magnet is alternately attracted and repelled by the magnetic poles to vibrate the diaphragms and to vary the volumes of the compression chambers. The two compression chambers share one field core.

Abstract: The present invention proposes an air pump structure having driving effect. The present invention is characterized in that a swing element of the air pump is connected to a driving shaft. One end of the driving shaft has a poked part protruding out of a shell body of the air pump. Except having air-supplying function, the air pump of the present invention can drive a color disk or other devices of a water lamp. Another motor is not required for driving the color disk to rotate, thereby saving the cost of another motor. Moreover, the structure of the whole water lamp can be much simplified, resulting in convenience in assembly and reduction in cost.

Abstract: A method of detecting an air pocket in a concrete pump and minimizing the effect of the nozzle and boom reaction as the air pocket reaches the end of the boom. The hydraulic pressure of the pump is monitored to determine when a pump stroke contains air. Upon detection of air in a pump stroke, an alarm is sounded and the pump is slowed to minimize the effect of the air pocket when it reaches the nozzle of the boom.

Abstract: Disclosed herein is a fuel metering pump for delivering fuel to rocket or jet engine having a motor driven face cam and a pair of reciprocating rolling diaphragm pump mechanisms movable through opposite suction and pump strokes. The face cam has a ramping cam surface that extends radially more than 180 degrees. This permits both pump mechanisms to be simultaneously in the pump stroke for a portion of the pump stroke so that they alternately reciprocate through the suction and pump strokes at essentially a constant velocity, thereby providing an essentially non-pulsating flow of fuel to the engine.

Abstract: An improved motor protection switch incorporates a parallel feedback component mounted in parallel to a heater in a motor protection circuit. The parallel feedback component senses the temperature of a compressor component. If tie temperature increases then the current flow through the heater increases. This causes a motor protector switch to open. In this way, the feedback component provides feedback from the compressor pump unit to the motor protection circuit more quickly than in the prior art.

Abstract: A diffusion flame nozzle gas tip is provided to convert a dual fuel nozzle to a gas only nozzle. The nozzle tip diverts compressor discharge air from the passage feeding the diffusion nozzle air swirl vanes to a region vacated by removal of the dual fuel components, so that the diverted compressor discharge air can flow to and through effusion holes in the end cap plate of the nozzle tip. In a preferred embodiment, the nozzle gas tip defines a cavity for receiving the compressor discharge air from a peripheral passage of the nozzle for flow through the effusion openings defined in the end cap plate.
