摘要： The disclosed systems and methods are related to a positive displacement compression for use in various applications including gas processing, air conditioning, refrigeration, etc., to produce an isothermal compression to enhance the compression efficiency. The heat exchange enhanced compression is conducted by the use of cylinders partially filled with incompressible fluid (e.g., oil) acting as a piston compressing working fluid (e.g., CO2). The isothermal compression is contemplated in various modifications. A variety of heat exchange (cooling) techniques may be arranged either within the compression chamber or the compression process may be embedded in the heat exchanger to cool down the working fluid (for example, CO2).

摘要： The present invention relates to a method and apparatus for generating pressure suitable in magnitude for powering micro-sized devices. The present invention typically comprises a gas generation chamber that is equipped with an activation element and filled with a gas-containing liquid. Powering of the activation element causes gas within the liquid to be released. Upon release a series of pressure distribution channels deliver the gas to a wide variety of peripheral microfluidic devices. A series of one-way valves and multi-chambered configurations allow for a wide variety of pressures to be generated from a single pressure generation device. By manipulating the scale of the pressure generation device, lab-on-chip, hand held, and bench top applications are possible and may readily be interfaced to allow a substantial amount of user control of the system.

摘要： For a pneumatically driven drainage facility, an intermediate station for receiving and boosting the liquid and air through the system. This intermediate station comprises a tank with an inlet for receiving the air driven liquid such that the liquid collects at the bottom of the tank. A first branch line communicating with the tank above the surface of the collected liquid extends outwardly from the tank for the passage therethrough of air which has entered the tank. A second branch line leads from the tank for delivering the collected liquid, a pump being provided for passing the liquid from the tank into the second branch line. The two branch lines join again at a point downstream from the tank in a descending conduit section, the first branch line entering the descending conduit section downstream from the entry therein of the second branch line. The descending conduit section ends with a U-shaped adjoining pocket.

摘要： A system for transporting a highly corrosive liquid solely by pressure differential without the need of mechanical pumps for transporting the corrosive liquid. The system includes a source of gas under pressure (78,82) and first and second corrosive liquid reservoirs (22,24) connected in parallel to the source via a valve (80) such that one or the other, but not both, may receive pressurized gas. A valve (20) connects one or the other, but not both concurrently, of the reservoirs to a point of use (10) of the corrosive liquid and is specifically designed for connecting the reservoir receiving the pressurized gas to the point of use. A valve (36) receives corrosive liquid from the point of use and directs the same to one or the other, but not both concurrently, of the reservoirs, and is specifically designed to provide the corrosive liquid to the reservoir not then receiving pressurized gas from the source. Air displaced from the reservoir receiving the corrosive liquid is directed to a scrubber (72) and then returned to the pressurized gas source for subsequent reuse.

摘要： The invention is an improved method and apparatus for determining the quantity of solids being conveyed in a slurry that is moving in a pipe. The method and apparatus combines a density-sensitive flowmeter (elbow meter) with a density-insensitive flowmeter (ultrasonic doppler flowmeter) to determine the quantity of solids conveyed in a slurry that is moving in a pipe. Velocity is determined by using a sonic flowmeter which is not affected by slurry specific gravity. Specific gravity is determined by dividing the signal from an elbow meter, which is a linear function of specific gravity, by the square of the sonic flowmeter signal. Numerous methods and apparatus are included to improve the accuracy of both the sonic flowmeter and the elbow meter.

摘要： A railway train made up of individual tank cars for interconnection and fluid communication with associated-like tank cars by flexible connecting conduits, wherein each tank car includes a wheeled chassis structure provided with coupling means for coupling adjacent tank cars. A tank is mounted on the chassis structure and has two lading conduits respectively coupled to the tank and in fluid communication therewith, each of the lading conduits having an outer end extending outwardly from the tank adjacent to the top thereof. Each of the lading conduits is connected to a vent conduit and to an eduction conduit with the vent conduit extending into the tank and having the inner end thereof terminating a predetermined distance from and near the top of the tank and with the eduction conduit extending into the tank and having the inner end thereof terminating near the bottom of the tank. Valves are provided to interrupt communication between the vent conduits and the lading conduits and between the eduction conduits and the lading conduits. The above structure enables tank cars to be loaded or unloaded from either end thereof.
