METHOD AND DEVICE FOR FEEDING A SYSTEM OF GENERATION AND DISTRIBUTION OF VAPOUR CONDENSABLE INTO MAKE-UP LIQUID

FLUID INJECTOR WITH VENT/PROPORTIONER PORTS

A fluid injector made of pressure rated components that attach to a fluid flow line so that flow is transferred from the flow line, into the injection unit and back to the fluid flow line.

Vent/proportioner ports provide back flow protection, prevent fluid from siphoning from the storage tank, provide an internal air release port and set injection ratios. A mixing control valve adjusts the injection ratios by mixing outgoing injection solutions with incoming fluid from the fluid flow line. Flexible bladders isolate one or more injection solutions within one storage container which are injected simultaneously at independent injection rates.

Ram jet propulsion for boat - with cylindrical valve which requires small gas vols. and displaces min. water forwards

The ram jet has a combustion chamber in which the fuel is ignited to generate gases. A hollow, cylindrical shutter coaxial to the centre of the jet has a profiled leading edge fitted with a circular gasket. The ends of the cylinder are guided in narrow ducts so that only a small gas vol. is required to drive it forward until the leading edge is forced against the inside of the entry duct to seal off the water intake. A small amount of water is expelled forward thus releasing more gases to provide the propulsion. The gases are collected in a chamber and passed intot he outer water jacket through a duct opened when the valve is slid forward. When the valve is closed the fuel intake is also stopped.

Methods of small volume pumping especially suited for oil recovery from stripper wells

A pair of inverted, concentrically mounted cups are lowered into a pool of liquid at the bottom of a well. The outer cup is a housing connected to atmospheric pressure via a capillary tube extending upwardly to the top of the well. The inner cup is a closed dome. Liquid passes through a check valve in the bottom of the housing and rises in the outer cup, since the capillary tube is open to the atmosphere and bleeds off the air inside the outer cup. Since the inner cup is closed, air is entrapped therein to limit the rise of liquid in it. When the capillary tube and, therefore, the two cups are pressurized, the check valve closes to prevent escape of liquid from the housing. The liquid rises in the dome to compress the air entrapped therein. When the capillary tube is suddenly opened again to atmospheric pressure, the compressed air entrapped in the closed dome of the inner cup drives the liquid violently up the capillary tube. Inertia carries a substantial amount of this liquid out the free end of the capillary tube and into a catch basin.

Water jet

A water jet is disclosed having a tank which forms a reservoir containing a liquid, such as water. An elongated conduit has one end fluidly connected to the reservoir while a nozzle is connected to the other end of the conduit. This nozzle, furthermore, has an opening with a cross-sectional area less than the cross-sectional area of the conduit. A valve is connected in series between the conduit and the reservoir, and this valve is movable between an open and a closed position. The reservoir is pressurized to a pressure in the range of 30-300 psi so that, once the valve is opened, water flows through the conduit and out through the nozzle at a high pressure and high speed water jet. This water jet can be used, inter alia, to clean industrial parts, such as engine blocks.

Air/water volume control system

Apparatus is described for controlling the volumes of water and headspace air in a water storage/delivery tank of an individual water well system that includes a pump for maintaining water within the storage/delivery tank and for maintaining the pressure in the tank within preselected limits. The apparatus enables the water level within the tank to be assessed, the air pressure within the tank to be assessed, and the respective volumes of headspace air and water within the tank to be adjusted independently of the pump. Three versions of the apparatus are described: a manually operated system, a semi-automatic system, and a fully automatic system. Use of the apparatus overcomes problems associated with the absorption of the air within the tank and resultant water-logging of the tank. Once this occurs, the pump is caused to switch on and off to an excessive extent. This in turn results in excessive power consumption and wear and tear on the pump and its associated motor, to say nothing of the nuisance the dwelling occupants experience because of such frequent stops and starts of the motorized pump.

Method and device for compressing a gaseous medium

The invention relates to a method and device for compressing a gaseous medium, particularly hydrogen. According to the invention, the compressing (Z1, Z2) of the gaseous medium ensues by using a liquid (D). The liquid (D) used is one in which the gaseous medium does not dissolve and/or one that can be separated from the gaseous medium without residues. To this end, the liquid (D) used is an ionic liquid, a high-boiling hydraulic oil or a liquid having a very low vapor pressure.

Fluid injector with vent/proportioner ports

A fluid injector made of pressure rated components that attach to a fluid flow line so that flow is transferred from the flow line, into the injection unit and back to the fluid flow line. The inlet flow is used to pressurize the storage tank and provide a solution to mix with injection solutions in the tank to provide an accurate preset or adjustable injection rate into the fluid flow line. Vent/proportioner ports provide back flow protection, prevent fluid from siphoning from the storage tank, provide an internal air release port and set injection ratios. A mixing control valve adjusts the injection ratios by mixing outgoing injection solutions with incoming fluid from the fluid flow line. Flexible bladders isolate one or more injection solutions within one storage container which are injected simultaneously at independent injection rates.
