Title: A process for producing dyeings and prints resistant to plasticizers
IPC: D06N3/00
Filed: 1952-02-14
Abstract: Textile materials of animal fibres or natural or regenerated cellulose or paper are dyed or printed and then coated or impregnated with a polyvinyl compound containing a plasticizer, there being used a water-insoluble dyestuff obtained by coupling a diazotized amine of the formula <FORM:0733160/IV (c)/1> with an arylide of 2 : 3-oxynaphthoic acid (or its 6 - alkoxy or 6 - halogen derivatives), 2-hydroxyanthracene - 3 - carboxylic acid, 2-hydroxycarbazole - 3 - carboxylic acid, 3-hydroxydiphenyleneoxide - 2 - carboxylic acid, 3 - hydroxydiphenylenesulphide - 2 - carboxylic acid or of 7 : 8 - benzcarbazole - 31 - hydroxy-21-carboxylic acid; in the formula R1 is hydrogen, alkyl, aralkyl, aryl or a hydroaromatic radical, the amide and NH2 groups are meta or para to one another and the nucleus a may be substituted by alkyl, alkoxy or halogen; both components are free from solubilizing groups.  These dyestuffs are stated to be resistant to bleeding into the plasticizers.  They may be applied by printing, padding or the ice colour method.  The fabric treated may be wool, silk, jute, linen, cotton or viscose.  In the examples (1) cotton goods are impregnated successively with an alkaline alcoholic solution of 2 : 3 - oxynaphthoic 2 : 5 - dimethoxy - 4-chloranilide containing formaldehyde and turkey red oil and with a solution of diazotized 3-amino - 4 - methylbenzanilide; (2) cotton is padded with an alkaline solution of 2 : 3-oxynaphthoic-o-anisidide and printed with a paste containing diazotized 3-amino-4-chlorobenz-o-toluidide; (3) cotton or viscose is printed with a paste containing the dyestuff 3-amino-4-methoxybenzanilide --> 2 : 3 - oxynaphthoic anilide (see Specification 210,081), an emulsion of a copolymer of vinyl acetate and butyl acrylate, a water-soluble condensation product of urea formaldehyde and ethylene glycol, and ammonium thiocyanate; the print is dried at 110 DEG  C.; (4) cotton or viscose is printed with a paste containing 2 : 3-oxynaphthoic 2 : 4-dimethoxy-5-chloranilide, the diazoamino compound from 3 - amino - 4-methoxybenzanilide and methyltaurine, caustic soda, turkey red oil and alcohol; the print is dried and acid-steamed to develop the colour.  In each of the above examples there is subsequently applied a mixture of polyvinyl chloride and dioctyl phthalate, and the coating is set by passing through a tunnel at 170 DEG  C.  A list of further suitable dyestuffs is given.

Abstract: 721,435. Switching systems for consumption apparatus. WILCOX & CO., Ltd., E., and WILCOX, E. R. May 20, 1952. [Feb. 20, 1951], No. 4062/51. Class 38 (4). [Also in Group XXXVII] The current of a system is limited during periods when the system voltage falls below a certain value by a relay comprising an undervoltage release switch whose contacts, when closed, short circuit the actuating element of a re-settable overload release switch. The undervoltage switch comprises a bimetal strip i which has a heater j permanently connected to supply terminals b, f and insulatingly carries a contact bar k, having contacts m, n cooperating with contacts o, d. The latter is carried by a rigid, fixed bar a connected at one end to the terminal b and supporting a spindle r which is urged to rotate by a spring s and carries a cradle t supporting a bimetal strip x. Strip x carries a contact y which co-operates with the contact o which is mounted on a spring p. When the voltage is normal, the contacts are closed as shown, so that strip x is shorted out, but if the voltage falls, strip i bends down and removes the short from strip x which, if an excessive current occurs, arches upwards until it clears a pin e, whereupon it is rotated counter-clockwise about pin r by spring 8 to separate contacts o, y. The operating current is determined by the pressure of a spring v and the size of strip x. The latter is restored, after cooling, by a push-button indicated at z. It is stated that the relay may alternatively be operated electromagnetically, or by a combination of the two methods.

Abstract: 912,023. Electric energy meters. SANGAMO WESTON Ltd. Feb. 5, 1959 [Feb. 13, 1958], No. 4127/59. Class 37. In an electric watt-hour meter for measuring the energy transmitted over three conductors 21-23, Fig. 3, comprising a single stator structure 26, Fig. 9, operating on a single disc, the stator carries a voltage coil P and two current coils FC, SC which are connected in lines 21, 22, respectively, coil SC which is given a high inductance by the inclusion of a magnetic shunt MS in the magnetic circuit being shunted by a resistor R to cause the current Ic, Fig. 5, through the coil to lag the line current I 2  by approximately 60 degrees. Reversal of the coil connections produces an effect of - Ic which is that of a current lagging the voltage E 1N  by # 3 =# 2 , the angle by which the current I 2  lagged voltage E 2N . The number of turns in coil SC is chosen to introduce a factor K equal to the ratio I 2 /Ic so that the power indicated E 1N  . I 1  . cos # 1 +E 1N  . KIc cos # 3  = E 1N  .

Title: Process for the purification of acrylonitrile
Filed: 1966-02-01
Abstract: Acrylonitrile, or a solution thereof containing water, contaminated with hydrogen cyanide and carbonyl compounds, either the HCN or the carbonyl compounds being present in a proportion between 0.1 and 3% with respect to acrylonitrile, is purified by distillation in a fractionating column the upper section of which is supplied with water having a pH of from 7 to 12, preferably between 8 and 11, whereby a stream of purified acrylonitrile and water vapour passes over from the top of the column.  If the concentration of HCN in the feed is greater than twice that of the carbonyl compounds, then the acrylonitrile, separated as a separate layer from the condensate, is free from carbonyl compounds but still contains HCN but may be freed from it by ordinary fractional distillation.  If the concentration of carbonyl compounds in the feed is greater than twice that of the HCN, then the acrylonitrile distillate is free from HCN but must be submitted to ordinary fractional distillation to remove carbonyl compounds.  The water supplied to the upper section of the column may be made alkaline by addition of sodium or calcium hydroxide, or of sodium carbonate.  When the removal of carbonyl compounds is the primary objective the water may be rendered alkaline by addition of sodium cyanide.

In a television receiver, the line structure is rendered less noticeable by applying the output of an oscillator operating at a frequency much greater than line frequency to the cathode-ray tube to reduce the intensity of the beam and cause each line of the image to be formed as a series of spaced dots, the oscillator being synchronized by the line synchronizing signals. The amplitude of the oscillations may be varied automatically in accordance with the brightness of the image. Fig. 3 shows a receiver operating with interlaced scanning. An oscillator 8 having a frequency of, for example, 2.7 Mc. is synchronized from the line synchronizing pulses 9, and oppositely-phased outputs 12, 13 obtained from the secondary of transformer 11 are applied through gate stages 16, 17 to a transformer 19 connected with an intensity-controlling electrode of the cathoderay tube (not shown). The gates are rendered effective alternately during successive frames by square-wave signals 24, 25 from multi-vibrator 22 synchronized by the frame synchronizing pulses 23. Fig. 4 shows the dot structure produced on the cathode-ray tube screen, the dots of alternate lines being staggered since the oscillations producing them are displaced in time by half a period. Fig. 1 (not shown) illustrates a receiver employing an oscillator with a single output to produce a dot structure in which the dots of successive horizontal lines are disposed in vertical columns.
