Abstract: Compositions and a process for manufacture are prov­
ided for synthetic polymer-propellant systems that form 
cohesive foamed structures from which aqueous solutions 
can be expressed, where the useful temperature range over

a poor solvent for the polymer and has a vapor pressure in the 
range of 10-35 psig at 20°C in combination with a small 
amount of a propellant that is a good solvent for the polymer; 
and where these coherent foamed structures can be formed 
even with aqueous solutions containing 0 to about 30% 
alcohol, provided that insoluble fine-particle solids that do not 
pack and become difficult to redisperse are included in the 
composition.

Filed: 1988-02-05
Abstract: Adjusted gas compositions having two or more components in desired 
proportions for particular industrial uses are obtained from available 
feed gas mixtures accompanied by recovery of one or more valuable indi­
vidual gases of high purity, by a novel selective adsorption-desorption 
scheme carried out in a multi-column PSA system. Following initial ad­
sorption of one or more components from the feed gas mixture at high 
pressure the sorbate-laden column is subjected to a high pressure rinse 
using as rinse gas the previously recovered more strongly adsorbed spe­
cies. After the rinsing step, the column is depressured to a selected 
level and purged with part of the unsorbed gas effluent discharged during 
the initial adsorption step until a preset amount of the earlier sorbed 
gas is recovered in the purge effluent as the readjusted binary gas mix­
ture of desired proportions. As an example, there is disclosed the pro­
duction from a starting gas mixture rich in hydrogen and carbon monoxide, 
such as that obtained from steam-methane reforming, an industrially use­
ful gas mixture having a desired H₂/CO ratio with the accompanying in­
dividual recovery of high purity hydrogen and carbon monoxide as by-prod­
ucts.

Title: Particle size measuring instrument with direct scattered light detection
IPC: G01N21/05
Filed: 1989-07-04
Abstract: In an instrument for measuring the size of 
particles entrained in a fluid stream, photodetectors 
are mounted on the walls of tubing shaping the flow of 
the fluid stream through a laser beam. The 
photodetectors generate electric current pulses in 
response to scattering of the light which is generated 
by the particles passing through the laser beam. The 
pulses generated by the photodetectors provide a 
measurement of particle size. The photodetectors are 
mounted either adjacent to the laser beam on the tubing 
walls or, alternatively, the tubing walls are mirrored 
above and below the laser beam and the photodetectors 
are mounted on the tubing walls at right angle bends of 
the tubing to receive the light reflected from the 
mirrored surfaces.
