Abstract: 523,302. Permutation locks. BUGG, K. C. Dec. 30, 1938, No. 37859. Convention date, Jan. 19. [Class 44] A locking lever 26 can be moved into and out of locking position by a knob 70 on a shaft 68 when the latter has been moved axially to the left to bring one of several notches 82 in a flange 78 on a disc 74 into engagement with a pin projection 84 on the lever 26. This movement is normally prevented by a ball 80 lying between the disc 74 and a second disc 62 which is secured, with the lever 26, upon a sleeve 52. The disc 26 has a number of grooves, Fig. 4, upon its face and a recess 94 big enough to receive the ball. The grooves are such that, by a suitable predetermined sequence of rotations of the disc 74, the ball can be moved from its lowest position, as shown, into the recess 94. When that has been done, the shaft 68 can be moved to the left. This movement permits a spring 86 acting upon a disc 88 to move a pin 90 to the left, removing it from half cylindrical recesses in a fixed sleeve 28 and the sleeve 52 and leaving that sleeve and the lever 26 free to be turned by the knob 70 through the flange 78. The discs 62, 74 may be replaced by parts having complementary conical or spherical surfaces to enable the lock to be used in an inclined or vertical position.

Abstract: In a process for the production of aqueous latices of polyurethanes free from emulsifiers derived from a polyhydroxyl compound of M.W. 300-10,000 an organic polyisocyanate and, if desired, a chain lengthening agent, a compound (A) containing at least one active hydrogen atom or at least one -NCO group and containing at least one salt type group or group capable of salt formation is used, which may replace the polyhydroxyl, organic polyisocyanate or chain lengthening agent in the case where compound (A) contains at least two reactive hydrogen atoms or at least two -NCO groups, either the said compounds or the resulting polyurethane being subsequently converted into a salt, the proportion by weight of salt type groups being 0.02 to 1%, but in the case of quaternary N atoms not more than 0.2% of the polyurethane and finally converting the polyurethane into an aqueous latex.  The compound (A) may be an alcohol or amine containing tertiary nitrogen, or an alcohol, amine or isocyanate bearing a halogen atom, or a carboxylic or sulphonic acid. In a typical Example (1) a solution of N-methyl-diethanolamine in acetone was added to a reaction mixture containing adipic acid-hexane-diol-neopentyl glycol polyester and 1:6-hexane diisocyanate.  After 3 hours at 50 DEG  C. dimethyl sulphate was added and heated.  A latex was formed by adding water and distilling off the acetone.  Protective colloids and stabilizers may be added after the formation of the latices.ALSO:Substrates such as woven and non-woven textiles, leather, paper, wood, metal and glass may be coated with an aqueous latice prepared in the absence of emulsifiers and being based on predominantly linear polyurethane masses prepared by reacting a polyhydroxy compound of M.W. 300 to 10,000, a polyisocyanate and, if desired, a chain lengthening agent, in which process, a compound (A) containing at least one active hydrogen atom or at least one -NCO group, and at least one salt-type group or group capable of salt-formation is used, in the case where compounds with groups capable of salt formation are used, either the said compounds or the resulting polyurethane masses being converted into the salt-form and in which compound (A) may replace the polyhydroxy compound, polyisocyanate or chain lengthening component wherein it has at least two active H atoms or at least two -NCO groups, the proportion by weight of salt-type groups being 0.02 to 1%, but in the case of quaternary nitrogen atoms not more than 0.2% of the polyurethane mass and finally the polyurethane mass being converted into an aqueous latex.  In a typical Example (1) a solution of N-methyldiethanolamine in acetone was added to a reaction mixture containing adipic acid-hexanediol-neopentyl glycol polyester and 1,6-hexane diisocyanate.  After 3 hours at 50 DEG C dimethyl sulphate was added and heated.  A latex was formed by adding water and distilling off the acetone and this latex left elastic non-adhesive films on glass plates.
