Title: Process for the production of coloured artificial filaments of high tenacity
IPC: D01F2/28
Filed: 1944-04-14
Abstract: Filaments having a basis of cellulose acetate which are free from high boiling solvents or plasticisers and contain a coloured (including black) pigment, are stretched until they have a tenacity of at least 2.5 grams per denier.  The filaments may thereafter be substantially completely saponified.  The coloured filaments obtained are of a high degree of fastness.  The pigments are water-insoluble substances which have no affinity for the filaments when applied in a conventional aqueous dyebath, and carbon black, lamp black and graphite are given as examples.  The pigment may be added to the spinning solution in the form of a solid pigmented base material, the said base being soluble in the spinning solution.  Sufficient of this material is added to the spinning solution to yield a dope containing from 0.1 to 5.0 per cent of pigment on the weight of cellulose acetate present.  The coloured filaments formed from this dope are then stretched until they have a tenacity of at least 2.5 grams per denier, while in the softened condition due to the presence of solvents, latent solvents or swelling agents, for example, steam. The stretched filaments may then be saponified by means of inorganic or organic bases, a number of which are specified.  In an example, to a spinning solution containing 25 per cent of cellulose acetate in 95/5 acetone/water is added sufficient black lacquer chip material to form a solution containing 26 parts of cellulose acetate, 74 parts of acetone/water and 2-5 per cent of carbon black on the weight of the cellulose acetate.  The solution is dry spun into 480 denier 40 filament yarn which is then stretched to ten times its length in steam at 135 DEG  C., and finally saponified in an aqueous bath at 80 DEG  C. containing 0.6 per cent of sodium hydroxide and 10 per cent of sodium acetate.  The yarns are pure black and have a tenacity of over 5 grams per denier.  Grey or neutral shade filaments produced by the invention may be topped with a small proportion of a direct dye, as in Specification 405,264. Specifications 459,164 and 510,761 also are referred to.

Patent GB-670317-A (GB)
Title: Preparation of organic arsonic acids and arsine oxides
IPC: C07F9/74
Filed: 1948-03-08
Abstract: Arsonic acids and arsine oxides are prepared by reacting diazotized solutions of arsanilic acid or nuclear substituted arsanilic acids or aminophenylarsineoxides or nuclear substituted p-aminophenylarsineoxides with compounds capable of arylation by means of aryldiazo solutions under weakly acid conditions using a cuprisalt as a catalyst, and subsequently liberating the desired compounds from the copper salts or copper complex compounds by normal methods.  The compound capable of arylation may be dissolved in acetone in which the salt of a weak organic acid is suspended or added in aqueous solution to buffer the mixture to a weakly acid state.  After the addition of the diazo-solution to p  the acetone solution of the compound capable of arylation and buffer, a solution of a cuprisalt may be added in such an amount that the newly-formed arsenic compound separates as a copper salt or copper complex compound and leaves sufficient cupri solution to catalyse the reaction.  The separated copper salt or copper complex compound may be washed with an organic solvent, air dried and dissolved in dilute sodium hydroxide solution, whereby the copper is precipitated as copper hydroxide removable by filtration.  In example (1) diazotized p-arsanilic acid is treated with cinnamic acid to give stilbene-4-arsonic acid; p-hydroxy-, p-chloro-, p-methyl- and 3-nitro-4-hydroxy-cinnamic acid react in the same way; p-methoxycinnamic acid under similar reaction conditions gives alpha - (p - arsonophenyl) - p - methoxycinnamic acid; (2) diazotized p-arsanilic acid and coumarin give 3-(p-arsonophenyl)-coumarin; (3) diazotized p-amino-phenylarsineoxide and coumarin give 3-(p-arsenophenyl) - coumarin; (4) diazotized p-arsanilic acid and 2-furyl-b -acrylic acid give 5 - (p - arsonophenyl) - furan - 2 - b - acrylic acid; (5) diazotized p-arsanilic acid and p-quinone give a mixture of 2-(p-arsonophenyl)-quinone and 2,5-di-(p-arsonophenyl)-quinone; (6) diazotized p-arsanilic acid and thiophene give 2 - (p - arsonophenyl) - thiophene; (7) diazotized p-arsanilic acid and furan give 2-(p-arsonophenyl)-furan; (8) diazotized 2-nitro-4-amino - phenylarsonic acid and p - hydroxy - cinnamic acid give 41-hydroxy-3-nitro-stilbene-4-arsonic acid; (9) diazotized p-arsanilic acid and cinnamonitrile give a -cyano-stilbene-4-arsonic acid.  Ortho- and meta-arsonilic acids which may be further substituted and similar arsineoxides may be reacted in the same way.  Specification 480,617 is referred to.

Title: System for identifying the phase of burst signals
IPC: H04N9/465
Filed: 1972-02-17
Abstract: 1338010 Television SONY CORP 17 Feb 1972 [18 Feb 1971 1 April 1971] 7367/72 Heading H4F In a colour television receiver for receiving PAL type signals, the chrominance signals for alternate lines are selected by switch 20, Fig. 2, the switch alternately selecting said line and the one line period delayed replica of said line (e.g. a line sequence 1, 1, 3, 3, 5, 5) for passage to a demodulator 22 for detection with the output of C.W. oscillator 30. When the receiver is switched on it is equally probable that the switch 20 and controlling flip-flop 25 will lock on to and pass lines having the (R-Y) chrominance component lagging the (B-Y) component by 90 degrees and having a B- burst (Fig. 4), whereas the C.W. oscillator 30 may have a phase synchronized with a previous B + burst. The circuitry described detects the selection of such (B -) lines and incorrectly phased C.W. oscillator output, and produces a responding correction of the phasing of switch 20. In the P.A.L; E.B.U. Specification for the twitching burst field blanking, Figs. 1A, 1B, 1C, 1D, the last colour burst before, and the first colour burst after the burst blanking period, are B+ bursts and the first line having the B+ burst occurs after an inerval from the beginning of the vertical syn pulse V s , according to a 6, 5¢, 5, 6¢ line sequence. The first line having the B - burst correspondingly occurs after an interval from the beginning of the pulse V s  according to a 7, 6¢, 6, 7¢ time sequence. The circuitry thus determines the interval from the beginning of the pulse V s  to the start of the first line selected by the switch 20 for four successive fields and causes the rephasing of switch 20, if the 7, 6¢, 6, 7¢ sequence is detected. The leading edge of pulse V s , (Fig. 6A) therefore sets (58, Fig. 6E) a bi-stable circuit 55, Fig. 3, which is reset by the first of a series of square pulses 63, Fig. 6D, derived from the burst signals B+ (B-), Fig. 6B, 6C (burst gate 27, detector 47, amplifier tuned to half line frequency 46, squarer 49). The four pulses 58 from the four successive fields (58A, 58B, 58C, 58D, Fig. 5E) are converted by integrator 51 into corresponding ramp voltages, such that only with the higher valued sequence 7, 6¢, 6, 7¢, Figs. 5H, 5I, 5J, 5K, 5L, 5M, do the ramps 59H, 59I, 59J, 59K reach above a threshold and produce a pulse 61 for rephrasing the switch 20. A modification, involving the addition of a second bi-stable circuit is necessary (Figs. 9 and 10, not shown), if the circuitry is to lock to the B - lines.
