Abstract: Threads, fibres, filaments, films and the like of acrylonitrile copolymers containing 50-98 per cent by weight of acrylonitrile and 50-2 per cent of at least one other polymerizable compound, are obtained by extruding a solution of the copolymer in dimethyl nitrosamine into a coagulating bath consisting of an aqueous solution containing at least 10 per cent by weight of potassium acetate, sodium acetate, calcium chloride or zinc chloride. Solutions containing 20-25 per cent of potassium acetate, 15 per cent of sodium acetate, 18 per cent of calcium chloride or 40 per cent of zinc chloride are preferred coagulating liquids. In an example, a solution in dimethyl nitrosamine of a copolymer of acrylonitrile and methyl acrylate is extruded into a 20 per cent solution of potassium acetate at 24 DEG C. The thread produced is withdrawn from the bath and passed round a system of rollers so that it is stretched in air. It is washed on an advancing reel and then stretched in steam at 100 DEG C. The thread is dried at 60 DEG C. in a relaxed state so that the fibres become crimped. In another example, a solution of sodium acetate is used as the coagulating liquid and the filments which are collected as a tow are cut to form staple fibres after being stretched in steam. Other copolymers referred to are those of acrylonitrile and vinyl acetate or vinylidene chloride, and ternary copolymers of acrylonitrile, vinyl pyridine and methyl acrylate or vinyl acetate. Specifications 706,263 and 738,293 are referred to.

Title: Hydraulic turbine speed control device
IPC: F03B15/06
Filed: 1964-05-23
Abstract: A control system for actuating the control members of a double regulation hydraulic turbine, such as Kaplan or Pelton turbine comprises servomotors 10a, 10b connected to the control members, such as a deflector 12a and blades 12b, the pistons 42, 43 of the servomotor being connected by linkage 63, 33, 64. Each servomotor has a control valve 40, 41 connected by linkage to a lever 30 and to a cam follower 16. The lever 30 is actuated by a speed input 1 to move the controls in the same direction, as indicated by arrows 44, 45. The linkage 33 carries a cam 15 which normally provides the feedback in response to movement of the servomotors from the input signal. If, however one control is too open, the linkage acts to move the servomotors in opposite directions to correct the error. Assume for example that the piston 43 is too far to the right, the link 33 will rotate anticlockwise about pivot 14a causing anticlockwise movement of the cam 15 which allows follower 16 to move downwards. The linkage thus lowers valve 40 to move 42 to the right and lifts valve 41 to move piston 43 to the left until the valves are recentred.

Patent ES-410295-A1 (ES)
Title: V-drive system
IPC: F16H48/30
Filed: 1972-12-21
Abstract: A low vehicle profile is obtained in a front wheel drive system by providing a V-drive axle center section at the rear of a transmission with a pair of forwardly extending V-shaped output or drive shafts. The output shafts are adapted to drive a pair of angled forwardly extending propeller shafts disposed on opposite sides of the center section so that drive can be transmitted to separate gear units located at each front wheel for individually driving the same. Equalization of power between the front wheels is accomplished by means of a conventional bevel gear differential located in one of the output shafts with drive to the differential being through a pinion gear keyed to an adapter sleeve serving as the axle center section input shaft. The front wheel drive system is easily converted into a four-wheel drive system by merely removing the adapter sleeve and inserting in its place a second differential of the worm gear type. By this arrangement input drive is then transmitted to the second differential with the drive divided by the worm gearing in such a manner as to have a portion directed to the first differential located on the center section output shaft and portion directed to a rearwardly extending propeller shaft for driving the rear wheels of the vehicle while still maintaining the desired low vehicle profile.
