Abstract: A fluid arrangement (10) for continuous delivery of volumetrically proportioned gases or like fluids includes a valve assembly (11) and a volumetric fluid storage bank (143), which has first and second sets (144, 151) of fluid storage chambers (145, 148, 152, 155). The valve assembly (11) alternately supplies a consumer with a blend of gases from the first set (144) of fluid storage chambers while charging the second set (151) of fluid storage chambers from pressurized gas sources (158, 159), and, upon a threshold depletion of gases from the first set (144) of chambers, supplies the consumer with a blend of gases from the second set (151) of fluid storage chambers while charging the first set (144) of fluid storage chambers from the gas sources (158, 159). The valve assembly (11) again supplies mixed gases from the first set (144) of chambers while charging the second set (151) of chambers.

Abstract: Applicants provide an application for a dust insecticide for pest control in residential, commercial or other properties. The applicator consists of an assembly, including a dust container and a compressed gas cylinder. The compressed gas cylinder is connected by a high pressure hose to a blowgun that has a barrel attached to it. At the end of the barrel is a nozzle. The nozzle receives dust through an elongated tube from a dust container. A venturi in a nozzle with a small opening proximate to the venturi creates a vacuum when compressed air is forced through it and sucks in dust from the dust container. The insecticide dust mixes with the compressed gas and is fired out of an outlet tube connected to the nozzle. The stream of high pressure compressed gas with an insecticide mixed to be directed at areas around building structures where pests may be found.

Abstract: A pressure regulator which includes a body. The body has inner walls defining an inlet port. Slidably moving within the inlet port is a hollow stem of a valve and piston assembly. The hollow stem is in slidable gas sealing contact with the inlet port. The valve and piston assembly includes a piston having a piston head with a valved opening therethrough. In the opening in the piston head is the arm of a plug. A body of the plug lies within the sliding piston held in place by a keeper spring, the keeper spring for maintaining a removed end of the plug arm against inner walls of the body. With such a structure, movement of the piston and valve assembly will be capable of unseating the plug from the valved opening in the piston allowing gas to flow from the hollow stem at the inlet port through an inner volume of the piston, through the valved opening of the piston head and into a regulated gas chamber defined in part by the inner walls of the body and an outer surface of the piston head.

Abstract: A system and method of pumping liquified gas. Applicants systems includes a liquified gas storage vessel and a smaller high pressure high pressure liquified gas storage cylinder. Applicant provides a pump between the two vessels for pumping the liquified gas from one vessel to the other. Applicants system also includes at least one heat exchanger through which the liquified gas passes as it is pumped from one vessel to the other, which heat exchanger cools the liquified gas that is being pumped to a temperature typically below the vaporization point of the gas.

Abstract: A fitting for engagement with a cylindrical compressed gas bottle. The fitting includes a valve for regulating gas between a regulated port of the body of the fitting and an outlet port of the body of the fitting. The body of the fitting is cylindrical and dimensioned to be hand held, the fitting includes a handle for pivotal engagement with the body, the handle to control the flow of gas from the outlet port.

Abstract: Applicant provides a novel liquified booster pump. The pump takes high pressure boosted gas to a higher pressure. The pump is a pneumatically driven liquified gas booster pump with a shuttle valve enclosed within a body of the pump. Furthermore, the gas which is use to be boosted is carried from an inlet on the body of the pump to an outlet on the body of the pump, the boosted gas being carried entirely within the body of the pump with no external tubing. The pneumatically driven booster pump has a double ended piston within the central body and at least one shuttle valve incorporated in the piston for transferring gas from one side of the piston to the other.

Abstract: A device for regulating gas pressure comprising a regulator body, the regulator body having walls defining a single high pressure inlet port and walls defining at least two regulated ports. The regulator body further comprising a high pressure manifold for providing gas to the regulated ports at the pressure it is received at from the high pressure port. The outlet pressure at the regulated ports is independently regulated.

Abstract: The Invention is a muzzle brake-bullet stabilizer, cylindrical in form affixed to the end of a rifle or pistol having internally a primary exhaust stage, a transition stage and nozzle. The primary exhaust stage being adjacent to the muzzle and consisting of a limited number of exhaust port holes drilled radially into progressively smaller internal bores serving as the primary exhaust stage and muzzle brake. A metering orifice being a strait cylindrical bore section of a diameter slightly larger than that of the bullet. The nozzle being conical with the small diameter being that of the metering orifice and increasing slightly thereafter, serving to increase the velocity of the remaining exhaust gases in a manner as to stabilize the bullet in its transition to supersonic velocity of the outside air from that of a negative velocity with respect to the exhaust gases.
