Abstract

An atmospheric tritium sampler is provided which uses a carrier gas comprised of hydrogen gas and a diluting gas, mixed in a nonexplosive concentration. Sample air and carrier gas are drawn into and mixed in a manifold. A regulator meters the carrier gas flow to the manifold. The air sample/carrier gas mixture is pulled through a first moisture trap which adsorbs water from the air sample. The mixture then passes through a combustion chamber where hydrogen gas in the form of H.sub.2 or HT is combusted into water. The manufactured water is transported by the air stream to a second moisture trap where it is adsorbed. The air is then discharged back into the atmosphere by means of a pump.

Device useful as a borehole fluid sampler

Patent Freifeld, Barry M.

The present invention provides a device comprising: (a) a proximal end of the device comprises an inner first conduit within the lumen of an outer second conduit, (b) a distal end of the device comprises the outer second conduit in fluid communication with a third conduit and a fourth conduit through a Y-shaped, T-shaped or U-shaped junction, (c) the third conduit terminates in a triggering mechanism, and (d) the fourth conduit is in fluid communication through a one-way valve, wherein fluid can only convey in a direction from the fourth conduit towards the second outer conduit, with an aperture.

Self timed data sampler

Patent Sadowski, Greg

A sampling circuit automatically resamples the data from another timing domain until the sampled data is represented correctly in the new domain by assuring that no metastable states exist. If a metastable state exists, a sampling signal recirculates through the sampling circuit until the metastable state no longer exists. A comparison of input data to sampled data is used to determine the existence of a metastable state.

Tidal sampler

Patent Hayes, David W [Aiken, SC]

An apparatus for pumping a sample of water or other liquid that uses the energy generated from the rise and fall of the liquid level to force a sample of the liquid into a collection vessel. A suction vessel and booster vessel with interconnecting tubing and check valves are responsive to an oscillating liquid level to pump a portion of said liquid into a collection vessel.

Variable percentage sampler

Patent Miller, Jr., William H. (Knoxville, TN)

A remotely operable sampler is provided for obtaining variable percentage samples of nuclear fuel particles and the like for analyses. The sampler has a rotating cup for a sample collection chamber designed so that the effective size of the sample inlet opening to the cup varies with rotational speed. Samples of a desired size are withdrawn from a flowing stream of particles without a deterrent to the flow of remaining particles.
