Abstract: MECHANICAL AND ELECTRICAL CONNECTOR     FOR JOINING ROTATABLE BODIES     Abstract of the Invention An interconnect device for mechanically and electrically joining two bodies in a rotational relationship comprises a tubular member secured to one of the bodies and extending through the other of the bodies.  A spring cooperating with the tubular member holds the bodies in an abutting relationship and electrical wires extend through the tubular member into each of the bodies in a manner to permit rotation of one of the bodies in relation to the other.  The electrical wires ex-rend from two ends and a central portion of the tubular member.          The device is adapted for use in a hand-held optical character reader and facilitates the handling thereof.

Abstract: ABSTRACT OF THE DISCLOSURE                Chromates are removed from aqueous alkali metal chlorate solutions by either of two processes. In the first process, a water-soluble sulfide such as NaHS is added to the chromate-containing chlorate solution, at a temperature of about 40-60°C and at a pH of 7-8, in an amount ranging from 70-200% (and preferably, 100%) of the stoichio-metric value required to react with the chromate; and then a water-soluble ferrous salt (preferably FeSO4) is added in an amount of from 30-100% (preferably about 57%) of the stoi-chiometric amount required; and the pH of the solution is adjusted so that the final pH is in the range of about 1.8 to about 3Ø  The soluble sulfide is converted to elemental sulfur and the chromated is converted to an insoluble, tri-valent Cr-containing material, which is subsequently removed from the solution.  The low pH of the filtered liquor renders it particularly suitable for use in a chlorine dioxide generator.  In the second process, The pH of the chromate-containing chlorate solution is first adjusted to a value within the range of 7-11, and preferably to about 11, and the solution is heated to a temperature of 40-60°C.  An "iron mud" is prepared by reacting a ferrous salt, e.g., FeSO4, with sodium hydroxide in ? molar ?proportions of 1 part ferrous salt to 1.5-1.8 parts of NaOH, the amount of ferrous salt employed being from about 3 to about 5 times the stoichiometric amount required to reduce the chromate present in the solution.  Then the "iron mud" is added slowly to the chlorate solution with vigorous agitation, and the pH is controlled to a value within the range of 10-12. The insoluble trivalent chromium-containing material so formed is subsequently removed from the solution.  This invention is effective in removing chromates from alkali metal chlorate solutions having a NaC1O3 con-centration in the range of 600-750 gpl, at which concen-tration previous processed for the removal of chromates are largely ineffective.

Abstract: ABSTRACT OF THE DISCLOSURE        For the fixing of a toner image applied to a data carrier with the aid of fixing cylinders a preheater is provided in front of the fixing cylinders when viewed in the direction of movement of the data carrier. The preheater comprises a saddle over which the data carrier runs by its tonerless side and heater elements which are arranged beneath the saddle.          The heating power of these heating elements and their arrangement below the saddle are selected in such a manner that the sum total of the heating power of all of the heater elements is at a maximum at the entry point of the data carrier and continuously decreases toward the data carrier exit point and in that the temperature of the saddle is constant across its full range.  In this manner the data carrier is very rapidly heated to the requisite temperature.

Abstract: AN APPARATUS FOR DETECTING TEMPERATURE VARIATIONS       OVER SELECTED REGIONS OF LIVING TISSUE, and METHOD THEREOF     Abstract of the Disclosure An apparatus for detecting temperature variations over selected regions of living tissue.  The invention relates to the apparatus and to the method of detecting said temperature variations for aid in the early detection of malignant tissue in the breasts.  The invention provides for the use of liquid crystals encapsulated between elastic flexible sheets which represent a composite film.  The crystals are responsive to changes in temperature of said tissue to display a color pattern on said film representative of said temperature variations.          The film conforms to the contour of the tissue to which it is applied, without materially deforming said tissue, by evacuating air from between said film and said tissue.  The color pattern produced on said film is observed and is recorded photograph-ically to obtain a thermogram of said temperature variations.          The contoured film and the tissue are fan cooled for a relatively short period of time to produce a more sensitive color pattern on said film representative of said temperature variations.     -i-

Abstract: ABSTRACT       A rolling mill having a roll stand with back-up rolls and two cylindrical work rolls.  The work rolls have roll-pass grooves associated in pairs with different roll-pass areas.  The driving mechanism of the rolling mill is coupled to the back-up rolls which excercise constant pressure on the work rolls during rolling so that these are in hard mutual contact and rotate with the back-up rolls.          The work rolls are axially displaceable in the roll stands between the back-up rolls when the latter are open so that a desired roll-pass groove can be positioned with its centre line coinciding with the central plane of the rolling mill.
