Abstract: A mobile oxygen point of use apparatus includes a standalone and portable mounting panel having a first side and a second side and is configured to be portably relocated within a facility by at least one human operator. A first set of oxygen flow regulators are mounted on the first side of the mounting panel and have multiple first oxygen inputs and multiple first oxygen outputs. A second set of oxygen flow regulators are mounted on the second side of the mounting panel and have multiple second oxygen inputs and multiple second oxygen outputs. A low pressure oxygen input is mounted on the mounting panel and a single pipeline or hose is configured to be connected from the low pressure oxygen input to a source of oxygen. Distribution plumbing connects the low pressure oxygen input to the multiple first oxygen inputs and the multiple second oxygen inputs.

Abstract: A combination pressure regulator includes a regulator body having an inlet port, an outlet port, and a combined inlet and outlet port. A first pressure regulator includes a first diaphragm, a first valve assembly, and a first biasing member that applies a first bias force to the first diaphragm to establish a first pressure regulator setting. A second pressure regulator includes a second diaphragm, a second valve assembly, and a second biasing member that applies a second bias force to the second diaphragm to establish a second pressure regulator setting. An input portion of the first pressure regulator is in fluid communication with the inlet port. An output portion of the second pressure regulator is in fluid communication with the outlet port. An output portion of the first pressure regulator and an input portion of the second pressure regulator are in fluid communication with the combined inlet and outlet port.

Abstract: A fuel gas and oxygen mixer for a gas torch comprises a tubular body having a mixing passage extending therethrough and having an upstream end connected to sources of a fuel gas and oxygen and a downstream end for delivering a mixture of the fuel gas and oxygen to a torch tip. The fuel gas is axially supplied to the upstream end of the mixer, and the oxygen flows along the outer surface of the body in the upstream direction from a point adjacent the downstream end of the body and then into the mixing passage through radial ports adjacent to the upstream end of the body. The counter flow of oxygen is through a passageway which provides for cooling of the mixer during normal operation of the torch and for the quenching of reversely flowing hot gases during a back fire.
