  • Patent number: 4632601
    Abstract: A system and process for dissolving certain noncondensable gases into geothermal waste water after the useful energy has been extracted from the geothermal fluid from which the noncondensable gases and the waste water are derived. A tubing is mounted in place within a wellhead casing which extends downwardly therefrom to an injection zone below ground. The length of the tubing is selected to at least correspond to the depth in the casing which provides a static waste water head pressure equal to the gas partial pressure required to dissolve at least a portion of the noncondensable gases into the waste water. The tubing has holes near the lower open end which communicates with the wellhead casing so that the noncondensable gases can flow into the wellhead casing and dissolve in the waste water flowing downwardly in the casing to the injection zone. A gas cap chamber is provided near the upper end of the wellhead casing for collecting the noncondensable gases which are undissolved and rise to the wellhead.

  • Patent number: 4459117
    Abstract: The liquid jet propulsion unit is driven by the conventional outboard motor. The drive of the motor directly rotates an impeller which draws up the water into an impeller chamber where it is moved by isentropic radially extending impeller blades. These blades have three progressive stages from inlet to outlet, i.e., axial, transition, and radial. In the delivery of the intake liquid to the outlet chamber the twisting turbulence is reduced and is straightened out and is further straightened by the outlet vane to give a stream greater lineal length and force through the outlet nozzle, which drives the craft forward. Since the vertical distance between intake and outlet is only a matter of a few inches, shallow draft boats can be driven successfullyin shallow and rocky water.

  • Patent number: 4457805
    Abstract: Apparatus and method for recovering clean solvent from a mixture of solvent and contaminants. The apparatus includes an open top tank mounted in a housing below a sink in which articles to be cleaned with solvent are placed. The sink has a tap through which solvent is directed so that the articles can be cleaned by hand in the sink itself. A disposable, plastic bag is receivable in the tank and the tank is closed by a cover. Contaminated solvent can flow from the sink, through the cover and into the bag in the tank. Contaminated solvent in the bag is heated by heating a liquid surrounding the side wall of the tank and below the bottom of the tank so that the solvent in the bag will vaporize. A tube leading out of the tank carries solvent vapor into a heat exchanger where the vapor is condensed to form clean, liquid solvent, and the liquid solvent is collected in a reservoir. A pump is coupled to the reservoir for pumping liquid solvent to the tap at the sink.

  • Patent number: 4445956
    Abstract: An improved method and material for securing a thin-edged deformable structure, such as a honeycomb core, so that the structure may be machined while it is in a generally stabilized condition. The material is a laminate which is bonded to one side of the structure to be machined. The laminate is then secured by vacuum and the structure is then machined in a desired manner. The laminate includes a first stabilizing layer formed from a mesh of fiberglass, nylon or the like and having relative large openings. The mesh is impregnated with a suitable epoxy or phenolic resin which acts as an adhesive to secure the mesh to the structure. A fabric of nylon or the like is applied over the mesh and bonded thereto. A third and final layer includes a non-porous plastic sheet which permits the laminate to adhere by suction to a vacuum chuck. After machining, the fabric and non-porous layers are removed, leaving the open mesh layer fixed to the structure to stabilize it.

  • Patent number: 4442642
    Abstract: A wall assembly comprised of a number of wall panels releasably coupled by clips of improved construction to spaced, vertical studs. Each wall panel has an end face and each clip has a number of tines or teeth which are forced or driven into the end face of the corresponding wall panel. The clip further has a resilient part mounted on a base part which engages the adjacent surface of a wall panel. The resilient part yields in one direction when it engages the adjacent flange of the stud as the wall panel is forced toward the stud in a horizontal direction. This permits the resilient part to pass by and thereby clear the flange of the stud, whereupon the resilient part snaps back behind the flange and thereby releasably couples the wall panel to the flange with the wall panel at the front of the flange. The resilient part is breakable from the body of the clip when the wall panel is pulled in a horizontal direction away from the stud, thereby permitting removal of the wall panel from the wall assembly.

  • Patent number: 4427495
    Abstract: Apparatus and a method for upgrading low pressure steam or brine, such as from a geothermal well, to prepare the steam or brine for any one of a number of uses, such as for conversion to pure, high pressure, high temperature steam for driving turbines. The system operates in a degasification phase in which a small amount of superheated steam is applied to the brine to scrub the same to cause the removal of concentrated gases therefrom. The degasified product is then pumped to a high pressure, heated countercurrently, and directed through a demineralized phase to remove the salts and solids in a liquid phase and convert the bulk of the water into pure, high pressure saturated steam. The steam output from the demineralizing phase can then be used to produce useful work, such as driving a turbine. In addition to forming saturated steam from geothermal brine, the system can be used to form pure saturated steam from impure water from any suitable source.
