IPC: C08G18/08
Filed: 1968-01-30
Abstract: 1,158,088. Redispersible polyurethane dispersions. FARBENFABRIKEN BAYER A.G. 30 Jan., 1968 [1 Feb., 1967], No. 4669/68. Heading C3R. Redispersible aqueous dispersions of cationic, cross-linked polyurethanes are obtained by (1) mixing a polyurethane which is substantially free from NCO groups and is present in an organic solvent which may contain up to 20% of water, with water, turbulence being produced at the same time, the quantity of water being such that the resulting dispersion has a solids content of not more than 60% by weight, based on the water, and (2) the turbulence is maintained until a sample of the suspension is insoluble in acetone, and (3) the liquid phase is partly removed by evaporation, filtration under suction or decantation, the polyurethane containing, before dispersion, (A) 2À0-20 milliequivalents per cent of quaternary ammonium and/or amine salt nitrogen formed by alkylation and/or reaction with acids with pk value of at least 4, (B) 1À0-60 milliequivalents per cent of basic tertiary amine nitrogen and (C) 2À0-20 milliequivalents per cent of a cross-linkable reactive group which will react with the basic, tertiary amine nitrogen at 0 to 80‹ C. in the presence of water. The polyurethanes are suitably prepared by reacting high M.W. compounds containing more than one reactive hydrogen atom, polyisocyanates and chain lengthening agents containing reactive hydrogen atoms, one of these components containing tertiary amine nitrogen. The tertiary amine nitrogen is conveniently contained in the chain lengthening agent, which compounds may be reacted in a solvent with a prepolymer derived from the polyisocyanate and high M.W. compound. Reactive groups which can be cross-linked and which are reactive with the basic tertiary amine nitrogen may be introduced into the polyurethane ether by the addition of compounds which contain this reactive group at least twice in the molecule or by addition of compounds which contain this reactive group at least once and in addition contain groups that are reactive with isocyanate groups. The preferred reactive group has the formula in which Ar may be a substituted aryl radical and Hal is chlorine or bromine. In examples compounds used to incorporate this group into the polyurethane are 1,3-dimethyl-4,6-bis-chloromethylbonzene, 1,5 - dimethyl - 2,4 - bis - chloromethylbenzene, 4,4<SP>1 </SP>- bis - chloromethyl - diphenylether and p-xylylene dichloride. Monofunctional alkylating agents or acids e.g. dimethyl sulphate, acetic acid, phosphoric acid, sulphuric acid, benzene-1,3- and naphthalene- 2,6-disulphonic acid or carbonic acid may also be added. Depending on the water content, the products are either dispersions which can be redispersed at any time, or pastes of the coarsely dispersed polyurethanes which remain capable of being worked up for an indefinite time.

Title: Improvements in or relating to valve mechanism for controlling servo-devices of the differential air pressure type
Inventor: CHOUINGS LESLIE CYRIL
IPC: F15B9/08
Filed: 1960-02-11
Abstract: 970,540. Fluid-pressure brakes. AUTOMOTIVE PRODUCTS CO. Ltd. Feb. 7, 1961 [Feb. 11, 1960], No. 4915/60. Heading F2F. [Also in Division G3] A servo-assisted vehicle-braking system which has a pedal-operated master-cylinder, not shown, is connected to a port 19 leading to a chamber 18 which is open to both the brake cylinder, via a port 17 in the piston 16 of a liquid-pressure master-cylinder 1, and through a hollow rod 12 to a cylinder 7 in the servo-piston 3; the rod 12 is attached to a piston 14 slidable in the cylinder 7. The servo-piston 3, which defines chambers 5, 6, incorporates diametrically opposed ports 21, 34 with which co-operate valves 22, 32 on stems 23, 33 which are interconnected by a yoke 37 pivoted to the rod 12; the stems 23, 33 have limited rocking movement relation to the yoke. The valve 32 is disposed in a casing 24 which is open to the atmosphere via a flexible tube 26 and a filter; a spring 39 urges the valve 32 to the closed position. Chamber 5 is connected to a source of suction and the parts occupy the position shown when the system is inoperative. When a pressure is created in the pedaloperated master-cylinder it acts in the pressureoperated master-cylinder 1 and in the cylinder 7 so moving the piston 14 and rod 12 to the left and closing the valve 22 whereby the chambers 5, 6 are isolated from each other; further movement of the piston and rod opens the valve 32 to admit atmospheric pressure to chamber 6 and causes leftward movement of the servo-piston 3 which forces the outer end of the rod 12 to seal the port 17. Continued motion of the servopiston 3 builds up pressure in the master cylinder 1 to a level greater than that exerted by pedal-operated master-cylinder, which greater pressure acts through the rod 12 on the piston 14 in opposition to the fluid-pressure from the pedal-operated master-cylinder acting therein. Since the pistons 16 and 14 are of different diameter these forces will balance, when the pressures in the two master cylinders have a given ratio, whereupon the rod 12 moves rightwardly, tending to close or lap the valve 32 and stop further translation of the servo-piston 3. Both servo-piston chambers may be normally connected to atmosphere and operation is effected by opening one to a suction or compressed air source.
