Abstract

In a short path length mass-spectrometer type of helium leak detector wherein the helium trace gas is ionized, accelerated and deflected onto a particle counter, an arrangement is provided for converting the detector to neon leak detection. The magnetic field of the deflection system is lowered so as to bring the nonlinear fringe area of the magnetic field across the ion path, thereby increasing the amount of deflection of the heavier neon ions.

Gaseous leak detector

Patent Juravic, F.E. Jr.

A mass-spectrometer type of leak detector is described for detecting gaseous atoms of a predetermined mass comprising: a rigid housing; an ion-detecting target means having an active detecting area; ionization means for ionizing the atoms to produce ions; accelerating means for accelerating the ions in a first direction; path defining means comprising a series of spaced apart baffles fixed to the housing and disposed along the path to define the boundary of the path, and to deflect ions which cross the boundary of the path; deflecting means comprising a magnet with generally opposed spaced apart pole pieces for generating amore »« less
Process and apparatus for the determination of concentration profiles of liquid or gaseous substances. [leak detector for crude oil or natural gas pipelines]

Patent Issel, W.

The process and apparatus are described for the determination of concentration profiles of liquid or gaseous substances along a path length, for example, crude oil and gas pipeline installations. A length of hollow conduit filled with a column of test medium is laid along a path length, the hollow conduit being constructed to permit diffusion of the substances thereinto establishing a distribution corresponding to the concentration profile to be determined and the column of test medium is pushed through the hollow conduit at chronological intervals past a sensor sensitive to the substances.
Gaseous leak detector

Patent Juravic, Jr., Frank E. (Aurora, IL)

In a short path length mass-spectrometer type of helium leak detector wherein the helium trace gas is ionized, accelerated and deflected onto a particle counter, an arrangement is provided for converting the detector to neon leak detection. The magnetic field of the deflection system is lowered so as to bring the non linear fringe area of the magnetic field across the ion path, thereby increasing the amount of deflection of the heavier neon ions.

Leak detector

Patent Gelston, N.E. II

A system is disclosed for detecting small leaks at low pressures in hermetically sealed units that includes a first flow circuit for connecting a test unit to a source of pressurized gas (air) to place the unit at a desired test pressure. The gas (air) is then rerouted through a second flow circuit containing a bubble chamber so that in the event of a leak, a stream of bubbles are produced in a liquid. The presence of bubbles in the liquid is detected by a doppler radar which provides an alarm signal in response thereto. The mass displacement of themore »« less
Resistive hydrocarbon leak detector

Patent Donaghey, L.F.

A resistivity sensor is described comprising: sensor means for sensing an organic gas, liquid or vapor. The sensor means comprises an intimate admixture of electrically conductive particles and a material capable of swelling in the presence of the organic liquid, vapor or gas; and means for electrically contacting the sensor means.
