Title: Improvements in or relating to dyeing
Filed: 1950-07-28
Abstract: Ingrain or melange effects are obtained in wool by dyeing or printing with a solution or paste containing (a) a condensation product of an aldehyde with an aromatic sulphonic acid or salt thereof, a water-soluble urea-formaldehyde condensation product, a water-soluble melamine-formaldehyde condensation product, a tannin, or an aromatic sulphonic acid containing at least three sulphonic acid groups or a water-soluble salt thereof; (b) acetic, hydrochloric, sulphuric, formic, phosphoric or lactic acid or an ammonium salt thereof; and (c) at least one dyestuff which will dye wool and contains at least two sulphonic acid groups; which solution or paste, during at least a part of the treatment has a pH below 5.5 when acids are used and below 6.2 when ammonium salts are present, and the proportion of substance (b) to substance (a) is not less than 0.2 : 1 by weight. In modifications, substances (a) and (b) may be applied, separately or together, before (c); substances (b) and (c) are applied together after (a); and substances (a) and (c) are applied together after (b). The wool may also be treated with formaldehyde before or during the treatment with substance (a).  Examples of condensation products of an aldehyde and an aromatic sulphonic acid are those of the general formula R-(CH2)n-R, where n is preferably 1 or 2 and R is an aryl radical containing at least one sulphonic group and if desired also an amino, hydroxyl, nitro, chloro or thiol substituent.  Suitable aromatic sulphonic acids containing at least three sulphonic acid groups are naphthalene trisulphonic acids and trisulphonic acids of monohydric, dihydric and trihydric phenols and alkyl-substituted phenols.  Any acid, neutral, direct, pre-metallized, chrome or fluorescent dye which will dye wool and contains at least two sulphonic acid groups may be used.  Two or more colour effects may be obtained by employing two or more dyestuffs, some of which may be free from, or contain only one sulphonic group.  Dyestuffs having two or more sulphonic groups dye the wool in darker flecks on a lighter ground, and if a mixture containing a dye with one sulphonic group and a dye with two or more sulphonic groups is used, the former dyes the lighter parts of the wool and slightly stains the fleck part, thereby giving contrasting colours.  The wool may be admixed with other fibres.  Many examples are given illustrating the use of cresol sulphonic acid-formaldehyde condensation product, ureaformaldehyde syrup, naphthalene trisulphonic acid, naphthalene-formaldehyde sulphonic acid, dinaphthylmethane-disulphonic acid, retene-formaldehyde condensation products, 2-naphthol-3,6-disulphonic acid and formaldehyde, melamine-formaldehyde condensation product, a condensation product of polyhydric phenols and aromatic sulphonic acid, and tannic acid as substance (a); acetic, phosphoric, sulphuric, formic and lactic acids and mono-ammonium phosphate as substance (b); and various chrome and acid dyes as substance (c).

Title: Improvements relating to paper machines
IPC: D21F1/36
Filed: 1929-06-21
Abstract: 327,069. Schubert, A. June 21, 1009. Guiding and stretching mechanism.-Automatic controlling means for maintaining the wire cloth of a paper machine in its normal path of travel by angular displacement of the guide roller there. of comprise contact rollers 4, Fig. 2, which when engaged by the edge of the wire cloth 2 operate switches A' or A<11>, Fig. 4, to start a motor 20 which through chains 21, 21<1> swings over the bearing of the roller 1 in the required direction to bring the wire back to its normal position on the roller. The electric gear is arranged at a convenient place above the machine on an auxiliary frame 9 or elsewhere outside the machine proper and is enclosed in a tank 25 containing oil to prevent short-circuiting and corrosion by the moisture, vapours &c. of the machine. The operation of a switch A<1> energizes an electromagnet 50 and completes the circuit R<1>, Fig. 4, of the motor 20. The roller 1 is thus deflected and also a spindle 30 is rotated and a cross head 31 traversed to tilt a disc 40 and make a contact 45 which energizes the magnet 60 and completes the circuit RII for reversing the motor 20 and bringing the roller 1 and cross head 31 back to the normal positions. The motor 20 then stops. Circuit breakers 71, 81 act as safety devices to interrupt the motor current whenever the cross head 31 approaches its extreme position as deteimined by arms 70, 80. The chain wheel 35<1> may be connected to the spindle 30 by a clutch and the spindle 30 may be rotated by a hand wheel 34 so that the normal position of the roller 1 is staggered in relation to the cross head 31. The motor will then be maintained running alternately forwards and backwards and the wire maintained reciprocating laterally within limits in order to distribute evenly the wear of the wire cloth on the suction boxes &c. The rollers 4 are respectively swung back into the inoperative position by eccentrically arranged counter-weights 6, when the wire cloth moves out of engagement.

Title: An improved system of aerial navigation, utilizing electromagnetic radiation
IPC: G01S1/02
Filed: 1929-06-24
Abstract: 314,310. Kolster - Brandes, Ltd., (Assignees of Kolster, F. A.). June 23, 1928, [Convention date]. Aerials; directive signalling to aircraft.-In a system of aerial navigation a conical space 14, Fig. 1, above a landing field 10 is circumscribed by an upwardly directed conical zone 13 of electromagnetic radiation produced by concentrating the wave-energy of a conductor, both spaces extending down to a point 11 on the field 10. An aerial 18, Fig. 5, placed along the axis 21 of a paraboloid reflector 16, of conductive material, sunk in the ground at 11, and energized by an oscillator 34 through a modulator 35 and amplifier 36, produces the substantially hollow cone-shaped radiation field 13. The wavelength employed is preferably four times the focal length of the reflector or the latter may be an odd multiple of a quarter wavelength. The radiation produced may be characteristically modulated. The inner solid cone 14 may be filled with radiation either of different wavelength or differently modulated, for example by speech currents for directing the navigator, by arranging a second aerial 31, Figs. 4, 5, in the form of a ring surrounding the reflector axis. Reactive phase shifting means 33, divides the conductor into two halves substantially equal in length to half the wavelength of the radiation employed, and possessing potential nodal points at their centres, to one of which the transmitter 32 is coupled. When employing only the hollow zone, the receiving aerial is correctly polarized if it is similar to the conductor 18 of the transmitter, and extends substantially parallel to axis 21. With the double zone method, an aerial independent of the polarization of the radiation. such as crossed conductors extending in a horizontal plane should be used.

Title: A process for improving artificial resins
IPC: C08G8/26
Filed: 1936-07-13
Abstract: Artificial resins are prepared by treating with hydrogen, in the presence of hydrogenation catalysts, resins prepared from cyclo-aliphatic ketones alone or from preponderating amounts of the said ketones and small amounts of phenols, cyclic alcohols and/or aldehydes.  The treatment with hydrogen may be effected in a melt or in solution, and the softening points of the original resins are thereby raised, and their colour is lightened.  Metals of the 8th group of the periodic system, activated or non-activated, are mentioned as catalysts, and they may be precipitated on carriers. Temperatures of 150--250 DEG  C., and pressures of 180--200 atmospheres may be employed in the hydrogenation process, though, with some catalysts, lower pressures and temperatures suffice. According to examples: (1) a resin obtained by heating cyclohexanone and methyl cyclohexanone with a methanol solution of potassium hydroxide is dissolved in decahydronaphthalene, a chromium - activated nickel catalyst added, and the mixtures treated, at 170 DEG C. and 180 atmospheres, with hydrogen.  When absorption of hydrogen is completed, the solution is filtered and the solvent distilled off in vacuo; (2) a resin obtained by boiling cyclohexanone with sulphuric acid is dissolved in cyclohexane, a chromium-activated nickel catalyst added, and the mixture treated, at 180 DEG  C. and 200 atmospheres, with hydrogen.  The solvent is then distilled off; (3) a resin obtained by heating a mixture of phenol, crude cyclohexanone containing cyclohexanol, and crude methyl cyclohexanone containing methyl cyclohexanol, with an aqueous solution of formaldehyde and boric acid, is dissolved in methanol.  An activated nickel catalyst is added, and the solution treated, at 180 DEG  C. and 200 atmospheres, with hydrogen.  After some hours, the solution is filtered and the solvent distilled off in vacuo.  Specifications 146,498 and 170,351, [both in Class 2 (iii)], are referred to in the Provisional Specification.
