Filed: 1966-05-04
Abstract: Polyurethane-forming solutions which are non-flammable (defined) comprise a solvent which is a chlorinated hydrocarbon, a polyurethane prepolymer obtained by reacting a diisocyanate with a linear polyester, polyether, polyhydroxy polymers of conjugated diene hydrocarbons or castor oil having a M.W. of 700 to 5000 and in which the ratio of NCO groups to reactive hydrogen groups is 1.1:1 to 12:1, and a curing agent which is an aromatic diamine, an aliphatic hydrocarbon diol or a hydroxy amine.  The solvent may be trichloroethylene, sym. dichloroethylene, perchloroethylene, dichloromethane, sym. dichloroethane, sym. tetrachloroethane, 1,1,2 - trichloroethane and 1,1,1-trichloroethane.  Conventional diisocyanates, especially aromatic diisocyanates, and conventional polyols are used to form the prepolymer. Suitable curing agents are 4,41-methylene bis-chloroaniline, ethylene glycol, propylene glycol and triisopropanolamine. Compounds of the general formula HSA where A is a thiazole, thiazoline, oxazole, imidazole or imidazoline radical may be added to the solution to accelerate the curing of the polyurethane. The solutions are suitably prepared by preparing a solution of the prepolymer in the chlorinated hydrocarbon solvent, preparing a separate solution of the curing agent in a solvent which may itself be flammable and mixing the two solutions, the resulting mixture being non-flammable.ALSO:Glass plates and the interior of metal storage tanks may be coated with a non-flammable polyurethane forming solution comprising a solvent which is a chlorinated hydrocarbon, a polyurethane prepolymer obtained by reacting a diisocyanate with a linear polyester, polyether, polyhydroxy polymer of a conjugated diene hydrocarbon or castor oil having a M.W. of 700 to 5,000 and in which the ratio of NCO groups to reactive hydrogen groups is 1.1:1 to 12:1, and a curing agent which is an aromatic diamine, an aliphatic hydrocarbon diol or a hydroxy amine.  The mixture is subsequently cured at room or elevated temperatures. In Examples (1) a solution of a prepolymer derived from 2, 4- and 2, 6-toluene diisocyanates and polypropylene ether glycol and 4, 4\sv-methylene-bis-2-chloroaniline in a mixed solvent of trichloroethylene, methylethyl ketone and dichloromethane used to coat a glass plate and (3) a solution of a prepolymer derived from 2, 4- and 2, 6-toluene diisocyanate and a mixture of polyesters which are poly (tetramethylene adipate) and poly ethylene/propylene adipate) and 4-4\sv-methylene bis-2-chloroaniline in a similar mixed solvent is used to coat the interior of an aluminium tank.

Abstract: 531,271. Grinding-machines. STIFTUNG, A. P. July 7, 1939, No. 19824. Convention date, June 22. [Class 60] In apparatus for grinding profiled workpieces having sections of different curvatures and dimensions such as round or half-round files, the work is carried by rocking members mounted on a table which is moved angularly about a pivot on a second table according to the varying profile of the work. The fixed frame 1 carries a slide 2 which may be moved on rollers 3 in a direction parallel with the surface of the grinding-disc 4 by means of a hand-lever 5. A second slide 8 moves on ball-bearing rings 10 on the slide 2 and is urged axially of the grinding- disc by a spring 11 whose tension may be adjusted by a screw 13. The slide 8 can also be moved by a handle 14 on a shaft 15 connected by a lost-motion slot 20 with a pinion 16 engaging a rack 17 on the slide 8. The lost motion enables the slide to yield under the influence of spring 11. A pivot 21 on the slide 8 carries a table 22 fitted with stocks 23 and 24 for the work piece 25. The headstock 23 carries a crank arm 26 which is oscillated from an adjustable crank-disc 28 connected through gears 31, 32 to a shaft carrying an arm 33 operated by a second arm 34 on an offset shaft, the arrangement being such that the rocking movement of the work is accelerated near the ends of the movement to prevent over-grinding of the edges of the file. The arm 34 is driven by a motor 37 on the table which also carries an operating handle 38 by which the table may be rocked about its pivot against a spring. 40. In operation the table is moved by the handle 14 to engage the work resiliently with the disc and the motor 37 started to effect a rocking movement of the work. The work is then moved along the grinding wheel surface by the handle 5 and the table is oscillated by the handle 38 as may be required for grinding the tapered end part of the file as shown in the upper part of Fig. 6. When round files are to be ground the work has a rotary movement about its axis instead of a rocking movement.

Title: Process for the manufacture of a stable water soluble yellow sulphuric acid ester
IPC: C09B9/02
Filed: 1930-06-30
Abstract: Sulphuric ester salts of leuco-a -anthraquinonyldiphenyltriazine monocarboxylic acid amide are made by treating the leuco compound with sulphur trioxide or an agent yielding the same in the presence of a tertiary base, and converting the resulting acid sulphuric ester into a stable salt. In examples, the leuco compound is treated with chlorsulphonic acid methylester in pyridine, or with chlorsulphonic acid in a mixture of dimethylaniline and chlorbenzene, and the product is isolated as the potassium or ammonium salt.  The product gives clear greenish-yellow shades when dyed or printed on textile fabrics and developed.  In an example of its use in printing, cotton is printed with a paste containing the ester salt, starch-tragacanth thickening, ammonium thiocyanate, sodium chlorate, and ammonium vanadate, and the prints are steamed, rinsed, malted, and boiled with soap.  The initial dyestuff is made by converting diphenyl - 1 : 3 : 5 - triazine - monocarboxylic acid into the chloride by means of thionyl chloride, and condensing the chloride with a -aminoanthraquinone. Specifications 186,057, 202,630, 202,632, and 231,889, [all in Class 2 (iii), Dyes &c.], are referred to.

Abstract: 519,162. Fluid-pressure brakes. BENDIX AVIATION CORPORATION. July 5, 1938; No. 19882. Convention date, July 6, 1937. [Class 103 (i)] In a hydraulic 'brake transmission the ratio between the pressures of the front and rear brakes of a motion which is controlled by a device arranged in the pipe line to one set, which comprises a valve which when a predetermined pressure is attained closes this pipe line and re-opens it on further increase of pressure, means being provided for rendering the device inoperative when desired. The device comprises internal opposed pistons 80, 92 having an axial passage 106 by means of which the brakes connected'to a pipe 24 are applied by the master cylinder connected to a pipe 20. When the pressure acting on the piston so attains a certain value the pistons move to the right, a valve 100 closes the pipe 24 and a ball valve 114 is released by a pin 52 to close the axial passage 106. On further increase of pressure the valve 114 is reopened and the increase of fluid-pressure transmitted to act on the piston 92 through the passage 106 moves the pistons to the left to re-open the valve 100 and re-establish the connection betweenthe master cylinder and the pipe 24. This cycle of operations is repeated several times during a brake application. In a modification, the passage through the differential piston is controlled by a valve at one end of the passage, the stem of which passes through the passage and engages the head of the cylinder to cause the valve to open.
