Patent GB-220964-A (GB)
IPC: D06P1/28
Filed: 1924-08-25
Abstract: The dyeing or printing of textile fibres is effected by impregnating or printing them with a mixture of a salt of an ester of a leuco vat dye (described in Specification 186,057) and an oxidizing agent, which is inactive in neutral or faintly acid solution but effective at higher temperatures, and then developing the dyeing by steaming; a catalyst to promote the oxidation may be added.  Thus the neutral or faintly acid solution may contain the ester of the leuco vat dye, a chlorate, and a catalyst such as potassium ferricyanide, ammonium vanadate, or osmium tetroxide.  Reserve effects may be obtained by printing the dyeing, before steaming, with salts having an alkaline reaction, such as sodium carbonate or acetate, or sodium thiosulphate, or reducing agents such as hydrosulphite N.F.; coloured effects are obtained by adding to the reserve paste mordant, basic, nitrosamine red, or vat dyestuffs.  According to an example, cotton is dyed or printed with a solution containing the ester salt of dihydro-indigo, ammonium vanadate or potassium ferricyanide and sodium chlorate, and then steamed for 2-5 minutes.  Specifications 203,681, 212,546 and 218,649 also are referred to.

Title: Improvements in sound apparatus for producing and receiving sound waves
IPC: H04B11/00
Filed: 1925-08-10
Abstract: 238,250. Signal Ges. Aug. 11, 1924,. [Convention date]. Mechanical w a v e filters. - A s o u n d emitter or receiver includes a mechanical wave filter comprising three or more vibratory structures connected in series and tuned to the same natural frequency, the coefficients of coupling and damping being uniform throughout so that the crests of the resonance curve of the system are evenly distributed. The coefficients of coupling are not less than 30 per cent, and the energy transmitted at the least favourable frequency within the working range does not fall below about one half of that transmitted at the most favourable frequency. The arrangement is particularly applicable to apparatus for detecting water noises or transmitting speech and music, and for coupling efficiently two vibratory structures of very unequal mass. Thus a heavy diaphragm 2, Fig. 1, for detecting subaqueous noises may be coupled to a light magnetic receiver 9 by a series of vibratory structures comprising diaphragms 4, 6, 8, mounted on cups 3, 5, 7, whose masses gradually decrease. Noises received by the above apparatus may be reproduced by a telephone receiver, Fig. 2, in which the diaphragm 16 is coupled to the output chamber 20 by a series of appropriately coupled resonating chambers 17, 18, 19, of gradually increasing volume and aperture, the natural frequencies of all the chambers being equal. A similar device may be applied to a loud-speaker, and, in order to tighten the coupling between the diaphragm 16 and the chamber 17 without disturbing the evenness of the resonance curve, one or more mechanical structures with gradually decreasing mass may be inserted between the telephone armature and the wall of the chamber 17.

Title: Process for the production of multi-colored woolen materials and the resulting products
IPC: D06P3/82
Filed: 1962-05-29
Abstract: Two-tone or multicolour dyeings on woollen materials in loose yarn or fabric form are obtained by treating them in a boiling solution comprising a metal salt having mordanting properties, a reducing agent and an acid giving a pH of 2-6, combining the woollen materials so treated with untreated woollen materials and dyeing with mordant acid or other wool dyes or a combination thereof.  The mordanting metals may be Cr, Cn, Co, Mn, Fe or Ac, the preferred salt being potassium or sodium dichromate.  The reducing agent may be sodium bisulphite, thiosulphate or hydrosulphite or potassium bitartrate. After rinsing and drying, the treated wool is combined by carding, combing, spinning, twisting, weaving, knitting, tufting or assembling with the untreated wool materials.  Additionally woollen materials pre-dyed in dark shades may also be combined with the said composite. The final dyeing step may be accomplished in the usual manner from a bath at a pH of 4-5.5 containing Glauber's salt and a condensate of stearyl diethylene triamine and ethylene oxide as well as other known auxiliaries, e.g. condensates of:- naphthalene sulphonic acid and formaldehyde, naphthalene sulphonic acid, formaldehyde and dihydroxydiphenylsulphone, 3, 4-dichlorophenylisocyanate and 4, 41-dichlor-2-amino-diphenylether-21-sulphonic acid as well as ethoxylated nonyl phenols.  Suitable mordant dyes for this process are well known as are the acid (including 1:1 and 1:2-metal complex and reactive type) dyes which may be co-employed.  Sometimes a mordant may be applied with the dyestuff so as to "top-chrome" the dye on the unmordanted material.  Examples are given particularly of two-tone dyeing tufted carpets.
