The other end of the line is connected to a housing having an internal pump chamber. A primary intake has one end connected to a reservoir of liquid and the other end connected to the housing concentrically about the secondary line.

Abstract: A down-hole pump provides positive displacement pump action within a production string of a producing well. The insert pump of the present invention fits within a crossover nipple that is adapted to fit on the end of a production string. The pump seals within an intermediate casing to direct high pressure drive fluid into the pump.

The combined flow of the drive and production fluids is then directed into a Venturi segment that creates a vacuum condition to increase production flow from the producing structures.

Abstract: Dispenser for dispensing simultaneously two liquids held in respective flexible containers, one within the other. Concentric tubular passages are provided for flows of the liquids from their containers when pressure is applied to the outer container. The inner passage has a narrow elonage form and terminates within the outer passage a final exit section of which provides a common conduit for both flows. A reduced liquid pressure is produced at the inner passage termination by having a tapered upstream end of the conduit overlapping the termination and the conduit is configured to inhibit mixing of the flows along its length. The two liquids are thus dispensed in a single stream in which, e.g., a colored flow from the inner passage is visible in the core of the stream. By adjusting the position of the conduit taper relative to the inner passage termination, it is possible to vary the proportions of the two components in the flow.

Abstract: A convection furnace using a shimmed gas amplifier to provide a flow of gas over a heating element is disclosed. The heating element is mounted in a substantially leak proof, pressurizable heating chamber. A gas amplifier in an upper plate of the chamber draws gas from a surrounding plenum into the heating chamber at a high flow rate. The pressure in the chamber increases from the input of pressurized gas and the heating of gas flowing over the heating element. The gas amplifier is provided with a toothed spacing shim which creates a stronger flow into the chamber. The stronger flow is capable of resisting the back pressure on the flow from the high pressure in the chamber. The heated gas passes through a plurality of orifices in a lower plate of the chamber to impinge on product traveling below the heating chamber on a conveyor and is recirculated via the plenum to the gas amplifier. The heat transfer rate in the chamber may be controlled by controlling the input flow rate to the gas amplifier.

Abstract: An improved liquid jet pump for water is described in which the water issuing from the jet pump drive nozzle passes into a nozzle mixing chamber where steam is introduced to nozzle outflow. This steam, traveling in the same direction as and converging upon the liquid driving stream, is raised to high velocities. These uncommonly high velocities of steam are attained both as a result of passage through a converging/diverging nozzle and the action of condensation upon the passing liquid stream. The liquid driving stream is supplied at a temperature which promotes immediate condensation of the steam molecules of the high speed steam jet. A process of momentum exchange immediately occurs within the drive nozzle mixing chamber between the high-velocity steam and the parallel-moving slower liquid stream with momentum being transferred from the steam to the liquid driving stream.

Without varying the primary inflows of liquid and vapor, the secondary flow varies inversely with the fluid flow resistance of the output load; and this can be used to vary the volume, pressure, and temperature of the output. The product of the pressure and volume of the combined flows can exceed the product of the pressure and volume of the primary flow, and change in the load resistance can be used to turn the secondary flow on and off for adding a material to the primary flow.

The mixture then passes into a diverging diffuser section and the heated liquid is discharged from the diffuser through a discharge conduit to a site of use.
