Title: Process of treating fibrous materials
IPC: D06P1/642
Filed: 1934-11-08
Abstract: Textile and other fibrous materials are improved by treatment with a solution or an emulsion of a salt of an imidoether, an imidothioether, or an amidine, containing at least one acid radical having at least six carbon atoms and/or an alkyl group having at least six carbon atoms, or of a derivative of any of these.  The substances are useful as washing, wetting and dispersing agents, for rendering viscose creaseproof, for waterproofing and delustring.  The solubility and stability of solutions of certain of the salts may be improved by adding an emulsifying or dispersing agent or a protective colloid, e.g. salts of urethanes containing sulpho or carboxyl groups, fatty alcohol sulphonates, oxyethylated fatty amines, carbohydrates, water-soluble albuminous products, &c.  In examples: (1) wool yarn is impregnated with a solution of stearimidoethylether hydrochloride in benzene and ethyl alcohol at ordinary temperature, hydro-extracted and dried; the wool has a soft feel and is waterproof; (2) montanimidoethylether hydrochloride, stearamidine hydrochloride and the ammonium salt of polyvinylbutylethermaleic acid are dissolved in water, and formaldehyde solution added.  Viscose fabric impregnated with the solution, squeezed and dried is fast to creasing; (3) a wetting agent is obtained by converting the nitrile of the fatty acid of coconut oil with ethyl alcohol into the imidoether hydrochloride, and transforming the latter by means of alcoholic ammonia into the corresponding amidine hydrochloride; (4) viscose yarn is delustred by treating for half an hour at 30--35 DEG C. with a solution containing barium chloride, stearamidine hydrochloride, stearimidobutylether hydrochloride and hexamethylenetetramine in water, followed by a treatment with sodium sulphate. Specifications 403,977 and 419,010 are referred to.

A receiver for quadrature transmission system comprises: quadrature and in-phase demodulators 40, 42; a reference signal source 16; and means 22 for correlating the outputs from the two demodulators to produce an error signal which adjusts the phase of the reference signal to minimize cross-channel interference. In order to provide initial frequency adjustment, and coarse phase lock of the oscillator 16 a D.C. signal 67 is modulated on to one channel d 2  at the transmitter and a tone 65 is modulated on to the other d 1 . The tone produces upper and lower pilot signals on the channel 14, which correspond to the upper and lower limits of the pass-band. These signals lock upper and lower frequency oscillators 60, 62, the outputs from which are mixed and divided by two in unit 64 to provide a signal at carrier frequency which synchronizes oscillator 55. Any initial crosstalk will produce a signal at the output of channel d 1 , demodulator 40 corresponding to the D.C. signal on channel d 2 . This is integrated by 66 to provide the coarse phase lock signal. As the source 16 approaches the correct phase, the signal from correlation detector 22 swamps that from integrator 66 and takes over control of the source 16. The oscillator 55 operates at a multiple m of the required frequency and phaseshifter 56 comprises a divider to which input, pulses are added or subtracted by the control signals from 54, 66, Fig. 3 (not shown).
