Pressurized cylinders are rapidly filled with acetylene gas and solvent in a staged process that is closely monitored by a control unit to assure that filling progresses with all critical variables maintained within safe bounds. An operator performs certain preliminary cylinder hookup tasks as monitored and prompted by the control unit. The control unit conducts the actual filling of the cylinder, carrying out this procedure in distinct filling stages with alternate injections of solvent and gas into the cylinder. The improved system enhances the safety and efficiency with which acetylene cylinders are filled.

Filling of acetylene cylinders

Lower portions of the outer wall of a pressurized gas cylinder are cooled during filling of the cylinder with a pressurized gas such as acetylene. A basket-like frame is installed atop the cylinder to support an annular manifold such that the manifold encircles the cylinder at a location spaced downwardly from the top of the cylinder. The manifold defines a plurality of fluid discharge openings which direct multiple flows of coolant toward the outer walls of the cylinder, whereby lower portions of the outer wall of the cylinder are bathed with a flowing curtain of coolant. The frame includes a C-shaped member which rests on the upper shoulders of the cylinder, and struts which depend from the C-shaped member to support the manifold.

Method and apparatus for cooling selected wall portions of a pressurized

A protective cap for a pressurized gas cylinder includes a ferro-magnetic body having an outer surface which is provided with a linear array of holes arranged to encode cylinder data in binary form. The presence or absence of a hole in each of a plurality of linearly spaced positions indicates one of two logic states. While the presence of a hole in a given position indicates one logic state, the absence of a hole at that position indicates the opposite state. Data is encoded in a repetitive but inverse form in two linear side-by-side rows. The data is read by a dual-head inductive transducer which is moved along the linear array such that each of the heads senses the presence or absence of holes in separate ones of the side-by-side rows to generate two separate trains of electrical pulses which are indicative of the encoded data, with one of the trains of pulses being substantially inverse in form from the other of the trains of pulses. The cap structure includes a base which is configured to be rigidly affixed to a neck of a pressurized gas cylinder, and an upstanding part which protectively shrouds a cylinder valve. The upstanding part also forms a yoke which can be engaged by a crane hook for lifting and moving the cylinder. The yoke preferably carries a knob-like projection which extends axially with respect to the cylinder, and which can be grasped to facilitate one's rolling the cylinder to move it manually from place to place.
