Title: Organosilicon polymers
IPC: C08G77/00
Filed: 1962-04-03
Abstract: Cross-linked silazane polymers having the repeating unit <FORM:0951521/C3/1> , wherein each R is a monovalent hydrocarbon radical, e.g. aryl, aralkyl, alkenyl and cyclo-aliphatic, and R1 is a divalent hydrocarbon radical of at least 2 C atoms and free of aliphatic unsaturation, can be made by heating, e.g. at 50 DEG  to 150 DEG C., a polymeric diorganosilylamine of the formula: <FORM:0951521/C3/2> wherein n has a value of from 5 to 150, with a metal salt selected from CuCl2, NiCl2, ThCl4 and CoCl2.  The diorganosilylamine polymers, in turn, are made by reacting a diorganodihalogenosilane with a diamine, H2N.R1NH2 as described and claimed in Specifications 949,134 and 949,896.  The cross-linking is best effected in solvent solution, e.g. benzene, toluene, xylene or mineral spirits.  The polymers may be further cross-linked by heating with an organic peroxide, desirably after admixture with a filler, e.g. C black, diatomaceous earth, CaCo3 or finely divided SiO2.  In a typical example (1), anhydrous ethylenediamine in xylene was reacted with diphenyldichlorosilane to give a hard, brittle, resinous diphenylsilylamine polymer; anhydrous cupric chloride was added to a xylene solution of this polymer and the resulting mixture was refluxed, filtered and freed of solvent to yield a brittle cross-linked silazane.  Uses: in the electrical field for insulation, dielectric and encapsulating purposes.

Abstract: 1, 028, 625. Tensioning yarns. LEESONA CORPORATION. April 3, 1963 [May 28, 1962], No. 13104/63. Heading D1D. A gate tensioner for strand material, e.g. textile yarn, comprises a fixed grid 80 mounted on a C-shaped member 70, a movable grid 90 pivoted on a shaft 92 and a spring 134 (Fig. 3 not shown) which urges 90 towards grid 80 through such a linkage that the output tension of the yarn tends to remain constant irrespective of the input tension. A flat plate 100 mounted at the mouth of the C-shaped element 70 has mounted therein an element 108 which is pivotable on a stud 102 and comprises a lower U-shaped portion 110 and an upper plate portion 112. The plate 112 has a slot 114 through which a locking stud passes and a scale 106 is provided on the wall 100 so that the element 108 can be accurately set in a desired pivoted position. The gate biasing spring 134 is attached to member 108 by an adjustable bracket 116 while the other end is attached by a link 132 to the bottom of a lever 126 pivotally mounted by pin 124 on the wall 100. A pin 128 on the lever 126 engages grid 90 which is thus urged towards the fixed grid 80. The force urging grid 90 towards frid 80 and thus the tension of the output yarn is adjustable by rotation of the element 108 so that the movement applied by spring 134 to pivot lever 126 about pin 124 is changed. In addition, the shaft 92 on which gate is pivoted is adjustably mounted so that the inclination of the grids to each other may be adjusted. A pivoted lever 136 (see also Fig. 4, not shown) having a finger 138 engaging behind a detent 140 in the pivoted grid 90 is provided so that the gate may be opened by operation of the lever for threading up. The lever 136 which is normally held by a spring 142 in a rest position determined by the setting on a screw 144, has a tab 148 which lies on the outside of grid 90 so that the extent of its outer movement is limited during operation. The fingers on the grid are preferably chrome plated. The device is shown (Fig. 1 not shown) fitted to a multiple twist spindle.
