Abstract: ABSTRACT OF THE DISCLOSURE           A plastic tube and tube end cap for installation in a metal tube or the like when the metal tube is positioned extending through a passage in a tube sheet, such that the plastic tube and end cap cooperate to accurately position an explosive charge which, when detonated, causes the plastic tube to expand outwardly against the metallic tube with such force that the metal tube makes intimate contact with the respective passage through which it extends in the tube sheet, without contaminating or damaging the metal tube in the process.  The subject plastic tube and tube end cap further cooperate so that when the plastic tube is inserted into the metal tube the explosive charge will be accurately positioned.  The end cap may optionally have openings therethrough which are located to relieve the expansion forces at a selected location produced during an explosion, and the end cap has a portion which can be deformed to permit positioning an explosive cord therein but which prevents movement of the cord when the deforming forces are relieved.

Abstract: ABSTRACT         A vacuum pump having a mechanically operated plunger or piston which is so arranged as to either fully open or fully close a supply of compressed gas. The compressed gas flows through a venturi tube to create a vacuum.  This vacuum in turn causes the atmospheric pressure to urge the plunger against a spring force to close the connection between the compressed gas and the venturi tube.  This will maintain the vacuum pressure between two predetermined limits.  As soon as the pressure in the vacuum chamber rises above a predetermined value the compressed gas supply is opened again to reduce the gas pressure in the vacuum chamber.  There are also disclosed a new desoldering tool, a power cylinder, clamping fixtures and suction cups operable with the vacuum pump of the invention.
