Abstract: ABSTRACT EXPLOSION PROOF AND WATERTIGHT ENCLOSURE WITH INSPECTABLE MEANS FOR VERIFYING VALIDITY OF RECLOSURE           When electrical equipment is used in a hazardous atmosphere, it must be enclosed in an explosion proof en-closure so an electrical spark cannot cause a fire or ex-plosion.  The present invention provides a means for assuring that an explosion proof enclosure which has been opened for inspection, repair or adjustment of the electrical apparatus is restored to its original condition.  To this end, a visually inspectable locking means is provided.  The locking means can be engaged only when the enclosure compartment and its asso-ciated cover are restored to their original explosion proof relationship.  The locking means does not exert any distorting force on the mating threads of the enclosure.

Abstract: Abstract of the Disclosure Membranes for use in chlor-alkali cells, made of a copolymer of tetrafluoroethylene and sulfonylfluoride per-fluorovinyl ether, have their selectivity improved, with resulting substantial decrease in consumption of electric power per mole of sodium hydroxide produced, by being heat-treated at 100 to 275° Centigrade for several hours to four minutes.  Desirably, the membranes are also subjected to pressure, such as up to 9.76 kilograms per square centimeter (10 tons per square foot). The current efficiency is sub-stantially increased, and the power consumption, per unit of sodium hydroxide produced, is usually decreased by about 10 percent or more.

Abstract: ABSTRACT OF THE DISCLOSURE    A property of a thin, infrared radiation-transmissive film of plastic or the like with specular surfaces is measured with substantial freedom from errors caused by wave interference effects, utilizing first and second infrared radiations having wavelengths selected so that one of the radiations is subject to greater absorption in the film material than the other radiation.          Beams of each of the radiations are directed from a multiplicity of points as on the diffusively reflective inner surface of a sphere to a surface of the film at a broad spectrum of incidence angles so that the beams traverse a multiplicity of paths through the film constituting a broad spectrum of path lengths.  Radia-tions leaving the film are intercepted and redirected from a multiplicity of points to a surface of the film at a broad spec-trum of incidence angles so that the redirected radiations also traverse a multiplicity of paths through the film constituting a broad spectrum of path lengths.  Each of the first and second radiations are detected with detecting means so arranged with respect to the directing and redirecting points that detected components of each radiation are added at substantially all possible phase angles and so that the components of each of the respective radiations at each of the possible phase angles approach equality of intensity as detected by the detecting means.  A response produced is indicative of the film property as a function of the ratio of the detected intensities of the first and second infrared radiations.     * * * * * * * * * * *

Abstract: ABSTRACT OF THE DISCLOSURE    A servo device is disclosed intended for amplifying the force in a mechanical control apparatus, movable in two opposite directions when said apparatus is displaced in either direction, comprising two gears rotatably disposed in a housing and coaxial with a rotatable shaft. The gears are driven in counter-rotation by a conical pinion or by two counter-rotating cylindrical pinions in driving relation to a rotatable servo motor. A nut is screwably arranged on screw splines on the shaft between the gears. When screwed along said splines, the nut comes into frictional contact via annular friction surfaces with corre-sponding annular surfaces on the gears. The nut, the splines and one of the gears makes a releasable driving connection with each other. Radially directed arms are attached to the shaft and the nut with control cable attachment means for transmitting the input operating force to one arm while an additional force is contributed from either gear via the shaft and splines  to the other arm.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention is an improved gas-absorption process for the recovery of a desired component from a feed-gas mixture containing the same.  In the preferred form of the invention, the process operations are conducted in a closed-loop system including a gas-liquid contacting column having upper, inter-mediate, and lower contacting zones.  A liquid absorbent for the desired component is circulated through the loop, being passed downwardly through the column, regenerated, withdrawn from a reboiler, and then recycled to the column.  A novel technique is employed to concentrate the desired component in a narrow section of the intermediate zone.  This technique comprises maintaining the temperature of the liquid-phase input to the intermediate zone at a sufficiently lower value than that of the gas-phase input to the zone to effect condensation of a major part of the absorbent-vapor upflow to the section.          This establishes a steep temperature gradient in the section.          The stripping factors below this section are selected to ensure that virtually all of the gases in the downflowing absorbent from the section are desorbed.  The stripping factors above the section are selected to ensure re-dissolution of the desired component but not the less-soluble diluent gases.  As a result, a peak concentration of the desired component is established in the section, and gas rich in that component can be withdrawn therefrom.  The new process provides important  advantages.  The chief advantage is that the process operations can be conducted in a single column in which the contacting zones operate at essentially the same pressure.  Thus, compared with prior gas-absorption processes, this process can be conducted in a system which is significantly simpler, more compact, and more reliable.
