  2. Diving regulator - Wikipedia

    en.wikipedia.org/wiki/Diving_regulator

    A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    Fuel and oxygen tanks should be fastened securely and upright to a wall, post, or portable cart. An oxygen tank is especially dangerous because the gas is stored at a pressure of 21 MPa (3,000 psi; 210 atm)) when full. If the tank falls over and damages the valve, the tank can be jettisoned by the compressed oxygen escaping the cylinder at high ...

    en.wikipedia.org/wiki/807_(vacuum_tube)

    The 1624 (VT-165) is an 807 variant with a directly heated filamentary cathode operating at 2.5 V, 2 A. The 1625 (VT-136) is an 807 variant with a 12.6 V heater and a 7-pin base. These tubes were used as RF power amplifiers in some of the SCR-274 and AN/ARC-5 "command set" transmitters of WW2. Postwar, 1625 tubes flooded the surplus market, and ...

  5. Pin Index Safety System - Wikipedia

    en.wikipedia.org/wiki/Pin_Index_Safety_System

    The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated with the gas mixture, which prevent connection of the cylinder to a yoke or pressure regulator with a mis-matched set of pins.

  6. Built-in breathing system - Wikipedia

    en.wikipedia.org/wiki/Built-in_breathing_system

    These are systems used to supply breathing gas on demand in a chamber which is at a pressure greater than the ambient pressure outside the chamber. [1] The pressure difference between chamber and external ambient pressure makes it possible to exhaust the exhaled gas to the external environment, but the flow must be controlled so that only exhaled gas is vented through the system, and it does ...

  7. Oxyhydrogen - Wikipedia

    en.wikipedia.org/wiki/Oxyhydrogen

    Oxyhydrogen is a mixture of hydrogen (H 2) and oxygen (O 2) gases. This gaseous mixture is used for torches to process refractory materials and was the first [1] gaseous mixture used for welding. Theoretically, a ratio of 2:1 hydrogen:oxygen is enough to achieve maximum efficiency; in practice a ratio 4:1 or 5:1 is needed to avoid an oxidizing ...
