Abstract: 1,143,797. Ferrocene cyclic thioethers. COLGATE-PALMOLIVE CO. 6 Oct., 1966 [7 Oct., 1965], No. 44751/66. Heading C2J. [Also in Division A5] The invention comprises ferrocene cyclic thioethers, which may be prepared by an adaption of the method used to prepare ferrocene cyclic ethers in Specification 1,143,796. The process to prepare thioethers of ferrocene consists in treating a ferrocene diol with a concentrated lower aliphatic acid (formic, acetic or propionic acid) and a small amount of mineral acid as catalyst in the presence of H 2 S, which is generally bubbled through the solution during the reaction. The acid catalyst is preferably sulphuric acid; however, HCl, BF 3 , HF, HNO 3 , polyphosphoric acid or p-toluene sulphonic acid may be used. The ferrocene diol starting material may be prepared by reduction of the corresponding diacyl with LiAlH 4 , phenyl lithium, sodium borohydride, an alkyl magnesium halide or with H 2  in the presence of a platinum or palladium catalyst. Preparation of the intermediate ferrocene diols, ferrocene diacyls, ferrocene dicarboxylic acids and ferrocene itself are also described.

Abstract: 1296813 Automatic thickness control GENERAL TIRE & RUBBER CO 13 Aug 1970 [5 Sept 1969] 39081/70 Heading G3R  In a system in which two sets of calendar rolls each produce one layer of a laminar sheet, screwdown of both sets of rolls is normally automatically controlled in dependence on the thickness of the laminar sheet and any difference between the adjustments of the two screwdowns prevents operation of the appropriate screwdown until the difference is eliminated. In Fig.1, pairs of calendar rolls 11, 12, 13, 14 produce two separate rubber sheets between which are sandwiched tyre cords before they emerge between rolls 12, 13 as a composite sheet 10. The thickness of this composite sheet is measured near one edge as shown by a radiation gauge 21 the output of which controls, through relay units 25, 26, a pair of reversible AC screwdown motors 27, 28 adjusting the thicknesses of the two sheets at the edge concerned. The screwdown adjustments, which are at low speed, are,respectively transmitted through selsyn units 50, 52, 49, 51 to a differential gear 53 which operates a switch 56 or 57 if the difference is outside predetermined limits so that, through units 25, 26, the appropriate one of the two motors 27, 28 is stopped until the continued adjustment of the other motor restores the difference between the limits. Gauge 21 then makes a thickness measurement at the opposite edge of the sheet and further screwdown motors 31, 32 are operated to adjust thickness at this edge. A further selsyn system associated with a differential gear 42 ensures that the difference between screwdown adjustments at this end of the rolls is maintained between predetermined limits. Switches are provided for manually controlling operation of the screwdown motors at low or high speed.
