A method of repairing and maintaining a pipe or pipe joint comprises applying a plurality of components to form a cooperative combination that strengthens, seals and protects the pipe or pipe joint. The initial components of the system seal, repair and/or protect the underlying structure, and the final component of the system binds the initial components to the underlying structure forms a strong cover strengthening and protecting the pipe and/or pole.

In order to measure the leakage power of a communications signal using a burst signal, with respect to adjacent channels, an input signal containing a modulated signal is subjected to A/D conversion in an A/D converter 23 and then written into a waveform memory 25. The input signal read from the waveform memory is demodulated to digital data by means of a demodulating section 29. An extraction region calculating section 33 detects the position of a synchronizing word in the digital data demodula...

A conveyor line conveys plural containers. A first sampler means moves the containers to a position at which a leaking liquid inspection apparatus is provided. A second sampler moves the containers to a position at which the entering air inspection apparatus is provided. A first stopper interrupts the containers at a position of the first sampler. A second stopper interrupts the vessels at a position of the second sampler. A third stopper is provided on the upstream side of the first and second ...

A pressure sensing system formed in a monolithic semiconductor substrate. The pressure sensing system comprises a pressure sensing device formed on the monolithic semiconductor substrate. Pressure sensing device is adapted to be disposed in an environment for developing an electrical pressure signal corresponding to the pressure in the environment. The system includes driver circuitry formed in the monolithic semiconductor substrate. The driver circuitry is responsive to input electrical signal ...

A method for repairing and concealing a crack in the interior surface of a basement wall, and for draining water admitted through the crack into a drain at the base of the wall. The method involves the steps of covering the crack, along the length thereof and down to the drain, with a thin, narrow strip of a water-absorbing, water-wicking fabric such as a layer of plastic foam or woven cotton. Thereafter a thin barrier layer of an elastomeric caulk composition is spread thereover and beyond the ...

Leak-detection system and method for detecting a leaking container. The system includes an enclosure defining a cavity therein surrounding the container, which container may be a nuclear fuel rod having fission products leaking through a breach in the exterior surface of the fuel rod. The fission products are capable of adhering to the exterior surface of the fuel rod as the fission products leak through the breach in the fuel rod. A radiation detector is in communication with the cavity for det...

An apparatus for estimating the locality of a leaking spot in a pipeline which conveys a fluid, the apparatus comprising: a pair of detectors located on the pipeline at positions spaced from each other by a certain distance l and adapted to detect pressures P.sub.1 and P.sub.2 and pressure gradients .differential.P.sub.1 /.differential.x and .differential.P.sub.2 /.differential.x at the respective positions; and an operating unit adapted to calculate the locality of a leaking spot on the basis o...

An electrically conductive metal is arranged within a passage for sodium having leaked, and the temperature change of the electrically conductive metal attributed to the heat of vaporization of which the sodium mist deprives the electrically conductive metal upon contact with the latter and subsequent vaporization is detected. The temperature change of the electrically conductive metal is detected in the form of a change in the current or voltage conducting property, and current corresponding to...

The present invention is relative to a deflection yoke in which a leaking magnetic field preventing member is formed without a magnetic body, such that coil winding parts are formed opposite to and apart from each other at a predetermined distance in the inside of a case formed in the same curvature as that of a flange part of a separator and coils of a predetermined diameter are wound therearound at a predetermined number of turns; a current which can form the current of direction contrary to a...

A liquid jetting pump of the present invention is constructed such that an intra container liquid is sucked into a cylinder 3 through a suction valve 9 by moving a vertically movable member 4 up and down, and the intra cylinder liquid is jetted out of a nozzle 29 through a discharge valve 31 from a stem 28. A plurality of ribs 10 are protruded in a peripheral direction from a lower edge part within the cylinder. Engagement recessed portions 11 are formed in inner parts of the upper surfaces of t...
