Abstract: A tightness-gauging device and a meter for gauging a pressure's sustainability pt for a pressure vessel or system are provided. A pressure is produced against the test fluid inside a piston cylinder communicated with the tested vessel or system by a fixed-pressure supplying assembly including a weight, a piston, and a piston cylinder successively arranged coaxially and vertically. An equation RL=pt/C is used to represent the tightness of the pressure vessel or system. The equation pt=p(p?0.5?p)?t/?p is used in the meter for gauging the pressure's sustainability pt to express the pressure's sustainability, where p is the fixed test pressure, t is the elapsed time for the fluid to leak completely, C is the cubage of the pressure vessel or system, ?p is the drop value of the pressure, and ?t is the elapsed time for the pressure to descend from p to (p??p) caused by the leakage.

A method for the maintenance of a wire stripper device is disclosed comprising removing a section of a sectioned shaft by removing the coupling collars retaining the joints of the shaft sections.

Abstract: A sealing tightness measuring device and a pressure-retaining capability measuring gauge for a pressure container or system is provided. A pressure is produced against the testing fluid inside a piston cylinder communicated with the tested container or system by an assembly including a weight, a piston, and a piston cylinder successively arranged through a coaxial plumb bob. An equation RL=pt/C is used to represent the sealing tightness of the pressure container or system. The equation pt=p(p?0.5?p)?t/?p is used in the pressure-retaining capability measuring gauge to express the pressure-retaining capability, wherein p is the fixed testing fluid pressure, t is the elapsed time for the fluid to leak completely, C is the volume of the pressure container or system, ?p is the drop value of the pressure, and ?t is the elapsed time for the pressure to descend from p to (p??p) caused by the leakage.

Abstract: A wire stripper adaption as disclosed comprises an output limiter to limit a splitting point of an insulation from an insulated wire at a first predetermined distance. The output limiter is suspended in any position radial to the wire leaving the wire stripper. An input guide is configured to axially align the insulated wire entering the wire stripper at a second predetermined distance radial to the wire entering the wire stripper. One of a circular hole and a semicircular hole defined in a body or the wire stripper itself cuts the insulation around the wire as it is circularly passed around a sharpened edge of the hole. The body defines three hole pairs configured to position an elongate cutting blade in the body for an operator to sharpen a first end of the elongate blade and a first and second beveled edges at an acute angle to the first end.
