Abstract: 1367271 Making conveyer belts; stretching wire or cable CONTINENTAL GUMMIWERKE AG 12 Feb 1973 [14 Feb 1972] 6775/73 Headings B3A and B3E [Also in Division B5] A method of manufacturing a conveyer belt 14 having pre-stressed reinforcing plies 4 of wire or cable form extending longitudinally therethrough comprises subjecting the plies to tensile stress between synchronously driven sets of rollers 1-3, 11-13 provided either side of a manufacturing apparatus in which the plies are embedded in and bonded to covering material to form a built-up web, wherein during conveying movement of the plies through the apparatus the torque applied to the set of rollers 1-3 is less than the opposing torque of rollers 11-13 by an amount needed to effect the conveying movement. A dynamic bracing system III is set up shown by vectors 7, and the resistance-cancelling torque 17 acts on the entry rolls 1-3 opposing the torque 7. Steel wires are fed from reels 5 of reel frame I to rollers 1-3 and pass through the apparatus where they are covered and the belt so formed is vulcanized. The completed belt 14 passes over rollers 11-13 to a take-up device (not shown). The rollers are driven by a common motor 6 through power lines 16 and an additional motor may be used to apply the torque 17.

[Class 34 (ii).] Articles having a porous structure, particularlyelectrical condensers having cellulose insulation prior to impregnation with oil or wax, are dried preferably while heated, by the repeated applications of a dry gas, the respective applications being followed by the removal of a substantial part of the gas. The condensers 13, Fig. 1, are placed in a receptacle 10 communicating with a vacuum pump 16 and with an apparatus for furnishing dry gas consisting of a refrigerating unit 23, a chemical drier 24, a supply line 22, and a pump 21. A gasholder may be provided for storage purposes. The condensers are first heated by a heater 12 at 86-115‹ C. for 30 minutes after which the pressure is reduced, the pump 16 operating for about 30 minutes. A valve 18 is then closed, dry gas is admitted through a valve 20 to produce any desired pressure in the receptacle and the heating continued for about 30 minutes, after which the gas is exhausted. Instead of exhausting the receptacle, dry gas at super-atmospheric pressure may be admitted, the pressure being afterwards reduced by opening the container.
