Systems and methods for producing a product gas are provided. In one embodiment, a system includes at least one separation bed to separate adsorbable components from a gas source, a valving means to selectively direct gas from the gas source to the at least one separation bed, at least one sensing device associated with the at least one separation bed to sense the progress of an adsorption zone within the separation bed, and a controller. The controller includes logic to read the output of the at least one sensing device and control the gas separation process based on the progress of the adsorption zone.

System and method for concentrating gas

Various equipment and methods associated with providing a concentrated product gas are provided. In one embodiment, the equipment includes an input device first and second sieve tanks, a variable restrictor, and a controller. In one embodiment, the method includes: a) selecting a desired output setting for the concentrated product gas from a plurality of output settings, b) separating one or more adsorbable components from a pressurized source gaseous mixture via first and second sieve tanks in alternating and opposing pressurization and purging cycles to form the concentrated product gas, and c) selectively controlling a variable restrictor based at least in part on the desired output setting to selectively provide flow between the first and second sieve tanks such that the flow for at least one output setting is different from the flow for at least one other output setting in relation to corresponding pressurization cycles.

Product gas concentrator and method associated therewith

Systems and methods for producing a product gas are provided. In one embodiment, a plurality of gas separation assemblies separate adsorbable components from a gas source using a plurality of micro-pumps to create gas flow through the gas separation assemblies. Various embodiments include implementation of various pressure swing adsorbtion (PSA), vacuum swing adsorbtion (VSA), and vacuum pressure swing adsorbtion (VPSA) systems utilizing the gas separation assemblies with micro-pumps. In other embodiments, micro-pumps and micro-pump assemblies are arranged in various configurations capable of providing a range of pressures and flow rates.

Systems and methods associated with providing a concentrated product gas utilizing a vacuum swing adsorption process are provided. In one embodiment, the system includes first and second sieve beds, a scavenger pump, and a controller. In one embodiment, the method includes: separating one or more adsorbable components from a source gaseous mixture via first and second sieve beds in alternating and opposing filling and purging cycles of a vacuum swing adsorption process to form the concentrated product gas and pressurizing the concentrated gas for delivery to a user. Other embodiments include selectively controlling a variable restrictor based at least in part on a desired output setting to selectively provide flow between the first and second sieve beds such that the flow for at least one output setting is different from the flow for at least one other output setting in relation to corresponding filling cycles.

Product gas concentrator utilizing vacuum swing adsorption and method associated therewith

A gas concentrating system is provided. The system includes, for example, a gas separation system having at least one separation space, at least one sensor connected to the separation space and providing at least one output signal indicative of the progress of gas separation, at least one pump system associated with gas separation system; and a controller. The controller includes, for example, logic reading the sensor output signal and logic controlling at least one parameter of the pump system based on the sensor output signal. The parameter of the pump system can be any parameter affecting the characteristics or operation of the pump system. Examples are disclosed but are not intended to be limiting.

A safety strap which maintains the hammer of a handgun in a cocked position. The strap can be drawn around the gun body and includes snap fasteners on its opposite ends. An opening formed in an enlarged intermediate portion of the strap fits over the hammer to prevent it from firing. The strap includes an additional pair of openings on opposite sides of the central opening for holding the safety on regardless of whether the safety is located on one side of the gun body or the other.
