IPC: B60T8/18
Filed: 1967-04-14
Abstract: 1,156,405. Brake pressure proportioning valves; valves. USTAV PRO VYZKUM MOTOROVYCH VOZIDEL. 14 April, 1967 [16 April, 1966], No. 17262/67. Headings F2F and F2V. A vehicle air brake pressure regulator comprises a diaphragm 15 attached to a piston 18 and enclosing a space 20 for a control air pressure supply, the diaphragm and a conical washer 14 being attached to an exhaust device 10 and a lever 12 moving the piston in dependence on axle loading to regulate the contact surface area of the diaphragm on the conical washer thereby regulating the air pressure supply to the vehicle brakes. Pressure air from an air tank (not shown) passes via an inlet 2 and a valve 4 to an outlet 6 and also passes via an inlet 21 into space 20. A control mechanism (not shown) moves the lever 22 in dependence on axle load so that a roller 24 acts on a bottom 19 of the piston 18. Downward movement of the piston 18 causes increase of the contact area between the diaphragm 15 and the conical washer 14. In the position shown the vehicle axle is not under load and the minimum braking pressure is required. When braking the control pressure in chamber 20 acts through the diaphragm 15 and conical washer 14 on the exhaust device 10 which closes the connection through outlet 6, space 5, orifices 10, 11 and exhaust orifice 12 and air pressure from the air tank passes via inlet 2, space 3, valve 4 and outlet 6. The pressure in space 5 increases until the forces acting on diaphragm 8 are balanced. Increase of axle load causes an increased contact area between diaphragm 15 and conical washer 14 thereby increasing the downward force acting on diaphragm 8 resulting in an increase in the permitted pressure in gate 5 and the braking system.

Filed: 1968-04-11
Abstract: 1,220,856. Pipe joints. MANNESMANN A.G. 11 April, 1968 [28 April, 1967], No. 17553/68. Heading F2G. A gastight joint between pipes, e.g. for drilling, consists of a tapered thread 3 and an abutment between the concave conical end 5 of the inner pipe and a convex mating shoulder 5 in the outer pipe which produces an expanding force 10 on the inner pipe tending to counteract the compressive force 9 due to the thread. Preferably but not necessarily, the angle a of the cone is larger than the angle of friction of the pipe material. Between the thread and the abutment there is a spherical seal head portion 4 which mates with a tapered surface 8 in the outer pipe. Due to the balance between forces 9 and 10 the sealing pressure at point 12 is adequate without producing fretting.

Title: Improved polymers and their preparation
IPC: C08G73/24
Filed: 1960-05-18
Abstract: Mononitrosoalkanes are prepared by reacting a fluorine-containing alkyl halide with nitric oxide.  The reaction preferably takes place in the presence of mercury and ultraviolet light at ambient conditions to produce a mixture containing the corresponding mononitrosoalkane and unreacted alkyl bromide, which is distilled in a column having at least 70 theoretical plates and a mononitrosoalkane containing less than 1% alkyl bromide is recovered from the distillation. Thus trifluoromethyl bromide or iodide yields trifluoronitrosomethane; pentafluoroethyl bromide or iodide yields pentafluoronitrosoethane; heptafluoropropyl bromide or iodine yields heptafluoronitrosopropane and chlorotrifluoroethylene telomers of trichlorobromomethane yields chlorofluoronitrosoalkanes.  In Example 1 a 50/50 mol ratio of trifluoromethyl bromide and nitric oxide are agitated in the presence of mercury and ultraviolet light for 24 hours, the pressure being kept at one atmos. by intermittently charging nitric oxide.  Distillation gave 60% yield of trifluoronitrosomethane.ALSO:A fluorine-containing nitrosoalkane is polymerized with an ethylenically unsaturated compound. The nitrosoalkane may be trifluoro-nitroso-methane pentafluoronitrosoethane, heptafluoronitrosopropane, nitrosoperfluorobutane, nitrosoperfluorooctane, trifluorodichloronitrosoethane, 1-nitroso- 1, 3, 5, 7, 7, 7-hexachlorononafluoroheptane and 1-nitroso- 1, 3, 5, 7, 9, 9, 9-heptachlorododeca fluorononane and the comonomer tetrafluoroethylene, trifluorochloroethylene, trifluoroethylene, and difluorodi chloroethylene as well as vinylidene chloride or fluoride, styrene, 1-1-2 and 1-1-3-trifluorobutadiene and methyl -1- chlorodifluorovinyl ether.
