Title: Improvements in process of treating textile materials
IPC: D06M15/233
Filed: 1932-11-07
Abstract: Water-insoluble polymerized vinyl compounds are incorporated in relatively small amounts in textile fabrics in order to improve their wear-resistance, to reduce their tendency to slip or ladder, and to render them more waterproof.  Fabrics thus treated may be used for making tops of fancy shoes.  When fabrics so treated are calendered between heated rolls, a glossy finish is produced with great adhesion between warp and weft.  The fabric may be woven, knitted, or netted fabric containing yarns, filaments, straw, or bristles, and may be of any textile material.  The material may contain yarns of a cellulose ester or ether, natural silk, wool, cotton, flax, or reconstituted cellulose.  The polymerized vinyl compound may be obtained by polymerizing vinyl esters such as vinyl acetate, propionate, or phthalate, the compound formed by treating a vinyl halide with zinc dust, or compounds such as styrene.  Polymerization may be effected by sunlight, light from a mercury vapour lamp, heat, or in other known manner in the presence or absence of catalysts such as uranium salts or benzoyl peroxide.  The compounds may be employed in various states of polymerization.  They are preferably applied as solutions in alcohol, benzene, toluene or other solvent.  They may be applied as aqueous dispersions with the aid of soap or Turkey Red oil. The fabric may be treated by dipping, or mechanical impregnation such as padding or spraying.  If desired the solution or emulsion may be locally applied in any desired pattern by printing or by the use of stencils, and dyestuffs may be added.  In an example, a twill weave fabric consisting of yarns of cellulose acetate is impregnated with a solution of polymerized vinyl acetate in benzene in a concentration of 1-2,5 per cent.  The amount of liquor taken up by the fabric is such that the amount of polymerized vinyl compound remaining on it is 1-2,5 per cent of the weight of the fabric.  Specifications 369,944, 369,945, and 372,327 are referred to.

Abstract: 998,985. Converting. PHILIP'S ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 17, 1962 [Aug. 21, 1961], No. 31690/62. Heading H2F. [Also in Division H3] In a line time-base for television apparatus, the saw-tooth current in deflection coil 8 is stabilized at 20 whilst the e.h.t. voltage V h  is stabilized by use of a saturable transformer which controls the resonant frequency of the flyback circuit in dependence on the load on the e.h.t. supply. It is shown that the effect of variation in cathode-ray tube beam current on the e.h.t. voltage may be minimized by controlling the ratio of the period of interruption of the valve 1 to the scanning period. As shown, the variation in e.h.t. current due to change in beam current causes corresponding variation in the inductance of saturable transformer 4 change in the resonant frequency of the flyback circuit and hence in the duration of the interruption period of valve 22 which corrects the change in e.h.t. voltage.

[Also in Division F1] A pneumatic motor drive for a ladle stopper rod (Fig. 1) comprises cylinders 3 actuating a vertical rod 5 through a cross-piece 7, the lower end 11 of each cylinder being connected to a compressed air valve 13 by a pipe 12 and the upper end 14 by a pipe 15 to a return valve 16 having a restricted opening to the atmosphere and a further opening to the atmosphere covered by a filter (18, Fig. 3). Three-way valve 13, Fig. 4, has a port 19 selectively open either to a compressed air line or to the atmosphere, a port 20 into pipe 12 and a port 21 open to atmosphere and separated from port 19 by a resilient plunger 22. Operation.-Compressed air supplied through port 19 closes plunger 22 against port 21 and passing through port 20 actuates pistons 10 whose rods eventually contact adjustable bolts on the cross piece 7. Further movement of the rods 9 raises rod 5 and therefore the ladle stopper rod to which it is connected. Air in the cylinder upper ends 14 closes valve 16 escaping through the restricted opening arid thus acting as a damper on the piston movements. In order to lower the stopper rod by a compression spring (6, Fig. 1) on the end of rod 5, port 19 in valve 13 is opened to atmosphere whereupon compressed air in the lower ends 11 of the cylinders causes plunger 22 to close port 19, opening port 21 to reduce said air to the atmosphere. Suction in the upper cylinder ends 14 causes valve 16 to open drawing air in through the filter (18, Fig. 3) and lowering pistons 10 to the initial position.
