Title: Gas detection apparatus
Inventor: HALL DENIS RODERICK
IPC: G01J3/42
Filed: 1982-09-09
Abstract: In contrast to known differential absorption gas detection systems which employ two lasers, a single laser 10 is sequentially tuned through a range of wavelengths, including one at which a trace gas to be detected absorbs and one at which it does not. Part of the laser output is passed through an area to be monitored to a detector 26, e.g. by backscatter, and part is passed through a reference cell 20 containing a sample of the gas to be detected to a detector 22. The presence or absence of the gas in said area is determined by electronic comparison of the detector signals by a microprocessor 36 after A/D conversion. A further part of the laser output may be deflected to a detector 18 to provide a reference signal. I.R. light going to the monitored area may be chopped, at 24, to enable a phase sensitive detection system 28 to be used. <IMAGE>

Title: Bed packing material
Inventor: HUFFMAN LOWELL E
IPC: B01J19/30
Filed: 1982-10-04
Abstract: A bed packing material piece 3 for use in filtering a gas, such as compressed air, is a coiled cylindrically-shaped member, spiralled about a central longitudinal axis. The bed packing material piece 3 is made of a polyolefin whose molecular weight may be as low as 2.5 million. Where the gas to be filtered is compressed air, the polyolefin is preferably polyethylene. The bed packing material piece 3 does not compress in normal use, thus keeping the void volume open. Thus, both entrained solids and liquids, are entrapped, even if the liquids are dissimilar, such as oil and water. Individual pieces of bed packing material are made by cutting from a solid core. <IMAGE>
