Title: Improvements in inks and in the marking of textile materials
IPC: D06P3/40
Filed: 1936-04-18
Abstract: Cellulose ester or ether sheet textile materials such as fabrics and garments are marked for identification purposes by an ink consisting of a suspension of pigment in a liquid containing a solvent or swelling agent for the cellulose ester or ether having a boiling point above 150 DEG  C., the liquid being free from solid thickening agents and film-forming substances.  The swelling agent is preferably a partial ester of a polyhydric alcohol with a lower mono-carboxylic acid.  The ink may be applied by rubber stamp since it has no tendency to clog the stamp or pad.  Markings are obtained which resist dyeing and other finishing treatments to which the textiles are subjected.  Esters of glycol or glycerol with acetic or formic acid such as the mono-, di-, or tri-acetate of glycerine or the mono-, or di-acetate of glycol may be used. Other solvents or swelling agents specified are benzyl acetate, ethyl lactate, diethyl tartrate, chlorhydrins, diacetone alcohol, and benzyl alcohol.  The solvent may be mixed with a non-solvent such as water.  The viscosity may be adjusted by adding a liquid such as glycerol, or butylene glycol.  A mixture of 90 parts glycol mono-acetate and 10 parts of glycerine is a preferred liquid for inks to be applied to cellulose acetate materials. When other liquids are used, the viscosity is preferably of the same order as that of the mixture specified above. The pigment used in the ink may be carbon black, iron oxide, Prussian blue, ultramarine, titanium dioxide, chrome yellow, vermilion, an insoluble vat dyestuff, an azo pigment dye, or a phthalocyanine pigment dye.  The pigment may be mixed with wood flour or cellulose dust separated from cotton linters.

Abstract: 702,207. Radio navigation ; limiter circuits. SPERRY CORPORATION. May 5, 1950 [May 7, 1949], No. 11177/50. Classes 40 (6) and 40 (7). [Also in Group XXXV] An automatic pilot (see Group XXXV) may be controlled by radio beam signals and is provided with electronic signal limiter circuits. Approach control, Fig. 1.-D.C. signals from a localizer receiver 103 such as that described in Specification 646,702 may be fed to modulator 104 to produce a signal of the appropriate frequency used in the pilot and combined with the heading error signal in summing circuit 28 together with localizer error corrector signals to compensate for cross winds. In a similar manner glide path signals may be substituted for altitude error signals in the elevator control channel. Bank integrator and limiter, Fig. 3.-The heading error signal is applied at 121, 122 to phase sensitive diodes 123, 124, the output of which is limited to selected valves by adjustment of a potentiometer 129 in the reference voltage supply. The limited D.C. output after integration by an R.C. network 128, 131, 132, is applied to modulators 133, 134 having a reference voltage introduced through transformer 135 in the cathode circuit. Pitch error corrector and cut-off, Fig. 5.-The error corrector circuit operates in parallel with a pitch integrator and limiter similar to Fig. 3 above. The altitude error signal applied to transformer 152 is amplified by pentode 153 mixed with a feed-back signal and amplified by triode 154, and output valve 155 to drive a two-phase induction servomotor 157 which drives a selsyn 151 to give the required correction signal. The feed-back voltage proportional to the servomotor speed is taken from a generator 164 and amplified by a triode 165 before mixing with the control signal. To prevent a signal in excess of the parallel limiter circuit output being passed, part of the input signal is amplified by a triode 166 and applied to a biased diode 168. When the signal exceeds the bias it is rectified by the diode to produce a cut-off bias on the suppressor grid of pentode 153. The cut-off circuit may be rendered inoperative by a relay 171 which grounds the suppressor grid. Yaw integrator, Fig. 6.-The angular acceleration signal is applied to a two stage integrator circuit having resistors 194, 195 in series with the capacitor arm of the second integrator whereby the output comprises the second integral plus a portion of the first integral developed across the resistors 194, 195. Specifications 663,913, [Group XXXVIII], 702,245, 702,261 and 702,262, [all in Group XXXV], also are referred to.

Title: Improvements in and relating to control systems for electric motors
Inventor: POOL WILLIAM JOHN
IPC: B66C13/54
Filed: 1955-04-21
Abstract: 790,376. Controllers. BRITISH THOMSONHOUSTON CO., Ltd. April 20, 1956 [April 21, 1955], No. 11577/55. Class 38 (3). A liquid controller LC in the secondary circuit of an induction motor has its position adjusted by means of a crank disc 19 which may be rotated, in common with a directional controller, by means of a reversible auxiliary motor. A slow-acting servo-mechanism S interconnects a connecting-rod 20, which is pivoted to the disc 19, and the controller LC. This mechanism comprises a piston 2, the position of which is adapted to be controlled in correspondence with that of a pilot valve 4 having a member 7 driven from the disc 19 so as to permit alternatively the connection of the front or rear spaces of cylinder 1 with a pressure supply 8 or exits 9. Thus, when the disc is rotated slowly, the controller follows this movement, but when the disc is rapidly displaced, so that the member 7 is quickly reciprocated, the piston 2 cannot follow the movement of the disc and the liquid controller remains stationary or almost so. In this manner, unnecessary reciprocating movement of the liquid controller is prevented when changing from driving operation of the induction motor to dynamic braking with an overhauling load, since the eventual position of the controller may be near the position it occupied before the transition from power to braking took place. Specification 588,209 is referred to.

Title: Improvements in or relating to a method for insolubilising artificial filaments, threads, fibres and the like obtained by the spinning of solutions of proteins
Inventor: MCGILLIVRAY ROY
IPC: D01F4/00
Filed: 1953-04-28
Abstract: Insolubilized coagulated protein filaments are produced from a bundle of filaments, which has been produced by extruding into an acid coagulating bath a solution of a protein in an aqueous solution of urea and treating the filaments with a hardening agent, by impregnating the hardened filaments in the bundle with an acidified aqueous solution of formaldehyde, drying the bundle at below 100 DEG C. and heating it to 140-180 DEG  C. until the individual filaments are insolubilized, by which is meant that, when immersed for 90 minutes in an aqueous bath containing 0.1 per cent sulphuric acid and 0.25 sodium sulphate at 97 DEG  C. the filaments do not change the bath into one which shows a positive biuret reaction.  The protein solution should preferably be matured for 48 to 144 hours at room temperature before being spun. The proportion of protein to urea is usually about 1 : 1.  The filaments are preferably stretched, e.g. 200 per cent, after impregnation with the acidified formaldehyde solution, and dried in the stretched condition.  The hardening agent is preferably formaldehyde, e.g. in the form of a saturated aqueous solution of sodium chloride or sulphate containing formaldehyde and having a pH of about 4.5.  The filaments should preferably be washed nearly free from salt.  The hardened filaments may be treated while still wet or after having been dried.  The acidified aqueous formaldehyde solution may contain 5-37 grams of formaldehyde per 100 cc. of solution and may have a pH of 1-4.  It is preferably free from salt.  The bundle of filaments may be a continuously travelling tow and is preferably impregnated by padding.  In an example a solution of groundnut protein in an aqueous solution of urea is spun into an aqueous solution of sulphuric acid and sodium sulphate, and the filaments are stretched in a bath of the same composition, relaxed in an aqueous solution of sodium sulphate and chloride, hardened in an aqueous bath containing 20 per cent sodium sulphate, 2.5 sodium chloride and 1.5 formaldehyde at pH 5 for 7 minutes at 50 DEG  C., washed substantially free from salts and dried at 80 DEG  C.  The filaments are then impregnated with an aqueous solution containing 10 per cent formaldehyde (and brought to a pH of 1.5 with hydrochloric acid) and stretched 200 per cent in air.  The stretched filaments are then dried in the stretched condition at 80 DEG  C. and thereafter heated for 30 minutes at 160 DEG  C. in the relaxed condition. Specifications 467,704, 467,812, 513,910, 533,952, 593,928, 597,497, 605,830, 623,460, 642,359, 654,513 and 742,261 are referred to.
