Abstract: Cleansing and disinfecting agents in cake form are obtained by kneading a phosphoric acid salt of a higher molecular weight hydroxy amine of the general formula: R1CONH(R2.NH)m.R3.(OR4)n.OH wherein R1 is a C8-C18 alkyl residue, and R2, R3 and R4 are ethylene or propylene groups, or in the case when m is 1 R2 may be a trimethylene group, m = 1 or 2, and n = 0 or an integer from 1 to 4, with phosphorus pentoxide without a solvent at elevated temperature not exceeding 150 DEG C. to form a phosphoric acid salt of the phosphoric acid ester of the hydroxy amine, and providing the resultant mass directly with the conventional additives used in the manufacture of soaps and then pressing into cakes.  The process may also be carried out by kneading the hydroxy-amine with a preparation of phosphorus pentoxide in phosphoric acid, the phosphoric acid salt of the phophoric the phosphoric acid salt of the phosphoric acid ester being thus formed in one operation.  In Examples: (1) phosphoric acid is added at 100 DEG C. to the stearic acid amide of N-hydroxyethyldiethylenetriamine in a kneader and phosphorus pentoxide is then introduced portionwise with continued kneading until the temperature is raised to 150 DEG C.; the strongly acid reaction product is then adjusted to a pH of about 3 by the addition of triethanolamine and then kneaded with lauric acid ethanol amide and formed into cakes; (2) as in (1) except that the palmitic acid amide of N-hydroxyethyl trimethylene diamine is processed; (3) phosphorus pentoxide is dissolved in phosphoric acid and the solution added at 100 DEG C. to the lauric acid amide of hydroxyethyl trimethylene diamine and the mass kneaded at 150 DEG C. for 6 hours. The product is adjusted to pH 4 to 5 with caustic soda, stearic acid ethanol-amide, urea, and perfume are then added and the mass formed into cakes.ALSO:Cleansing and disinfecting agents in cake form are obtained by kneading a phosphoric acid salt of a hydroxy-amine of the formula: R1CONH.(R2NH)m.R3.(OR4)n.OH wherein R1 is a C8-C18 alkyl residue, and R2, R3 and R4 are ethylene or propylene groups, or in the case when m is 1 R2 may be a trimethylene group, m is 1 or 2, and n is 0 or an integer from 1 to 4, with phosphorous pentoxide without a solvent at elevated temperature not exceeding 150 DEG C. to form a phosphoric acid salt of the phosphoric acid ester of the hydroxy-amine, and providing the resultant mass directly with the conventional additives used in the manufacture of soaps and their pressing into cakes.  The process may also be carried out by kneading the hydroxy-amine with a preparation of phosphorus pentoxide in phosphoric acid, the phosphoric acid salt of the phosphoric acid ester being thus formed in one operation.

Abstract: 1,193,269. Anti-skid braking systems for road vehicles. ROOTES MOTORS Ltd. 25 Aug., 1967 [31 Aug., 1966], No.38900/66. Headng F2F. A road vehicle braking system which prevents skidding when brakes are applied too severely, incorporates at least one brake pressure releasing device responsive to the rate of deceleration of the front wheels. The deceleration sensing and pressure releasing device is illustrated in Figs. 3, 4 (not shown). In an embodiment Fig. 1, pressurized fluid from a master cylinder 64 is fed via a servo operated valve in the deceleration responsive device 67 to a front wheel brake 60 and rear wheel brake 62, and via a similar device 68 to front wheel brake 61 and rear wheel brake 63. Pulleys 10 of the devices are coupled to the respective front wheel. If say front wheel 60 decelerates too quickly a flywheel in the device 67 overruns the pulley to open a valve (27) (Fig. 3, not shown) admitting air to the servo unit which shuts a ball valve (48) in the fluid pressure line to the associated front and rear brakes, by pressing down on a spring loaded piston of the servo. The piston, via a push rod normally holds the ball valve open. The push rod is slidable in a cylindrical chamber communicating with the fluid lines to the brakes so that as the push rod moves to its valve release position brake fluid is free to occupy the vacated volume in the cylinder and thereby the fluid pressure is reduced. In this embodiment braking pressure can be applied to an outer front wheel on a corner, even if the inner front wheel has little adhesion. Alternatively as shown Fig. 2, brakes on diagonally opposite wheels are connected to one fluid pressure line. Furthermore there may be two master cylinders, one to each fluid pressure line. The front to rear brake pressures may be in a ratio 70: 30 or 75: 25. Reference has been directed by the Comptroller to Specification 962,933.
