Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for determining the saturation temperature of a solution using the principle that a change in the temperature of the solution causes a correlatable change in light transmitted through the solution.  The apparatus, unlike prior art apparatus, prevents the condensation of steam evolved from a test solution in the vicinity of a test cell; and the method overcomes the problem of suspending solute crystals in the test solution by depositing such crystals on an inner surface of the test cell.  The apparatus and method disclosed provide accurate and precise results.

Abstract: ABSTRACT OF THE DISCLOSURE A separator for material which includes components of different specific gravities and sizes, includes a series of spaced, parallel shafts disposed in essentially the same plane, which may be tilted upwardly.  A series of non-circular discs, such as elliptical, three lobed, etc., are mounted on each shaft and interspaced with the discs on adjacent shafts.          A pipe, on which the discs are mounted, or a spacer mounted on the shaft, provides circular surfaces between the discs which clear the projections of the discs of adjacent shafts but when the disc surfaces between the projections come opposite the pipe or spacer, cause holes or spaces to be produced, through which material may fall, if sufficiently small.  As the discs rotate, they not only cause the holes to open and close, but also propel the material both upwardly and forwardly.  The discs on each shaft are normally in alignment, but the discs may be mounted on a shaft in a spiral relation, so that not only is the material pushed upwardly and forwardly, but also laterally.  Several sets of discs may be used, with the dis-charge end of one set being above the receiving end of the next set, so that the material will tend to be turned over as it falls from one set to the next.  A paddle may be used to enhance the turning, while the paddle may be rotated at a suf-ficient speed to break glass bottles or the like.  The holes produced by the rotating discs may increase in size from one set to the next.

Abstract: Abstract of the Disclosure The method for producing an aluminum wheel rim comprises axially pressing a thin walled cylindrical aluminum or aluminum alloy material under the action of compressive stress acting thereon through tapered portions of a die and a punch cooperating therewith in a press machine so that the diameter of the material is enlarged so as to form the required configuration of the rim, while the wall thickness of the material is increased at posi-tions where compressive stress is applied through the tapered portions of the die and the punch thereby increasing the mechani-cal strength of the material at positions where otherwise weaken-ing tends to occur due to the thinning of the wall thickness of the material by the roll working thereof.  In order to success-fully carry out the method, it is preferred to select the ratio H/D of the height H of the material with respect to the inner diameter D thereof to be equal to or less than 1.5, the ratio t/D of the wall thickness t of the material with respect to the inner diameter D to be in the range of 0.006 to 0.06 and the mean deformation resistance or mean flow stress of the material to be in the range of 10 to 25 kg/mm2, while the inclination angle of the tapered portions of the die and the punch is set to be in the range of 10 to 65°.            .
