Title: Improvements in or relating to the production of hair dyes
IPC: D06P3/30
Filed: 1955-06-13
Abstract: A process for the production of a hair-dye suitable for direct dyeing of hair at room temperature comprises combining equimolar amounts of an anionic dyestuff and a cation active compound containing at least 6 carbon atoms per molecule, whereby a dyeing, anioncation complex is obtained, and water-solubilizing the complex with a quantity of a solubilizing agent which is just sufficient for the purpose and which leaves the molecular anion-cation balance substantially unchanged. An anionic dyestuff is defined as one which contains a functionally acid group such as COOH, SO3H or OH groups.  Cation-active substances indicated are organic bases containing tri- or penta-valent nitrogen atoms and they may contain a lipophilic chain of 12-14 carbon atoms attached to a hydrophilic amine chain.  Solubilizing agents indicated are alcohols and condensation products of ethylene oxide with alcohols, phenols or naphthols.  In a modification of the process the quantity of solubilizing agent added may be reduced or omitted if the organic base has solubilizing groups attached thereto, e.g. the organic base may be condensed with ethylene oxide.  Preferably, the pH value of the dyeing solution is adjusted to below 7, e.g. 4.5-5.5, by the addition of an organic acid such as lactic acid.  Thickening agents, e.g. gelatin or condensation products of ethylene oxide with an aliphatic alcohol, may be added to cream the dyestuff, but the agents must be chosen so that the ionization equilibrium of the dye is not disturbed.  The thickener may take the place of the solubilizing agent.  In examples, hair dyeing aqueous solutions are made from lactic or acetic acids and Bleu chlorantine lumiere GLL, Noir diazol E, Rouge Kiton 6B, p-nitro-o-anisidine --> 8-phenylamino-2-naphthol - 6 - sulphonic acid, m - amino - sulphani - lide --> 8 - phenylamino - 2 - naphthol - 6 - sulphonic acid, Induline B, Induline RAL, Nigrosine LFM and Rouge Kiton Brilliant B, the cation active agents being octadecylpyridinium bromide, an ester of copra fatty acids with diethylethanolamine previously condensed with ethylene oxide and a lactate ester thereof, and the solubilizing agent being "Cemulsol 132" (a condensation product of a compound containing a naphthalene nucleus with ethylene oxide).  Other examples show the preparation of a cream dye from Noir diazol BH, octadecylpyridinium bromide, hydroxyethylene cetyl alcohol, lactic acid and water and a gel dye from Violet chlorantine 5BLL, octadecyl-pyridinium bromide, "Cemulsol 132," gelatin, lactic acid and water.

Title: Safety valves
IPC: F15B20/00
Filed: 1973-04-10
Abstract: 1422054 Valves TECHNOMATIC AG 10 April 1973 [14 Feb 1973] 17046/73 Heading F2V A valve device for controlling the supply and exhaust of working fluid to presses comprising two co-axial parallel-connected piston valve closure members 20, 22 which co-operate with conical seats 154, 156 respectively and are controlled by electro-magnetically actuated pilot valves 82, 84 is characterized by the members 20, 22 having bores accommodating control pins 42, 44 respectively, which pins are displaceable with respect to the pistons to actuate an electric switch in the case of incorrect actuation or breakdown. Actuation of the pilot valves allows the inlet fluid from inlet 14 to move the members 20, 22 towards each other and establish connection between the inlet and the consumer connection 18 via passages 38, 40 while the exhaust 16 is isolated. With proper actuation the two pins abut with their cylindrical ends 70, 72 at the position 28. If one of the members 20, 22 has not been fully actuated or one of the control pins has jammed or fails to take up its correct position, the conical section of one of the control pins moves to the position 28 and displaces a switch pin 122 to actuate two switches 132, 134 which shut down the plant. Since there is a possibility that the two members 20, 22 will not move in complete synchronism and thereby cause a shut down of the plant without real cause, a connecting passage 152 is provided to equalize pressures in the chambers behind the pistons during actuation.

Title: Method and apparatus for sharpening saw blades
IPC: B23D63/12
Filed: 1956-06-06
Abstract: 794,234. Grinding and polishing. ALBER, R. June 6, 1956, No. 17465/56. Class 60. Saw blades, especially band saws, are sharpened by means of a grinding wheel guided with a periodically changing feed speed over a tooth 3, which is moved at a preferably different periodically varying feed speed so that the speed of the grinding wheel relative to a tooth is low when treating the upper end of the tooth back d-a<SP>1</SP>, Fig. 2, and the upper end of the tooth face a-e, and is high when treating the tooth bottom b-d. The grinding wheel, whose feed speed is controlled by a cam disc 42 mounted on a continuously rotating shaft 15, is carried on a shaft 31 in a carrier 30 which is supported by a pivoted lever 36 provided with a roller 38 mounted for longitudinal adjustment. An intermediate pivoted lever 44 contacts the roller 38 and is also provided with a roller 43 held in contact with the cam 42 by the weight of the wheel and carrier. The section b<SP>2</SP>-d<SP>2</SP> of the cam lifts the grinding wheel at high speed over the tooth bottom b-d while sections d<SP>2</SP>-a<SP>2</SP> and a<SP>2</SP>-b<SP>2</SP> lift the wheel slowly over the tooth back d-a<SP>1</SP> and lower it slowly down the upper part of the tooth face a-e respectively. The band saw feed is actuated by a pawl 4, Fig. 4, pivotally connected to a carrier 6 on a shaft 8 which is in screwed connection with an adjustable length shaft 13-13<SP>1</SP> carried on a pivotally mounted lever 22. A roller 25 arranged for axial adjustment in the lever contacts an intermediate pivoted lever 18 also carrying a roller 19 which is in contact with a cam disc 16 mounted on the shaft 15. A rocking motion is transmitted to the lever 22 so that the pawl 4 moves one tooth under the grinding wheel per revolution of the cam 16. The section b<SP>1</SP>-d<SP>1</SP> of the cam moves the tooth bottom b-d rapidly while the section d<SP>1</SP>-a<SP>1</SP> moves the tooth back d-a<SP>1</SP> slowly past the grinding wheel. The section a<SP>1</SP>-b<SP>1</SP> allows a spring to move the pawl back to pick up the next tooth and the blade remains stationary while the tooth face a-b is ground. By varying the position of the rollers 25 and 38 different tooth spacing and depth can be provided for. During the rising and falling movement of the wheel the carrier 30 is also caused to rock about an axis parallel to and spaced from the spindle 31 so that the wheel swings in its own plane.
