Title: Automatic tool selection systems
IPC: G05B19/29
Filed: 1970-07-21
Abstract: 1309413 Programmed control of machine tools FUJITSU Ltd 21 July 1970 [23 July 1969] 35377/70 Heading G3N A tool code, punched on a tape PT together with numerical information, is fed to a controller NC wherein the stored address corresponding to a tool code is detected and sent through a line LA into a coincidence circuit COI. The address on line LA is compared with the actual address TA of the tool position, opposite to a transfer device CRT, of a tool store TM on a code disc CP rotated with the store and read by a detector DT. At coincidence, the circuit COI resets a flip-flop FF, or FR, which was set in dependence on the minimum travel to the commanded tool, to control a circuit determining the direction of travel of a motor M driving the store TM. At coincidence between the desired address and the actual address on the disc CP the rotation of the store is stopped and tool inter-change effected through the carrier CRT controlled by a circuit TCC.  The address code corresponding to a commanded tool code is determined from a shift register which is stepped by an oscillator during an initial search operation.

Title: Uniaxial orientation of polypropylene film

Abstract: 981,849. Polypropylene films. HERCULES POWDER CO. Sept. 19, 1963 [Sept. 28, 1962], No. 36915/63. Heading B5B. Uniaxially oriented film of stereoregular polypropylene is made by extruding a flat film of molten stereoregular polypropylene, quenching the molten film to the solid state, and then drawing it between differential feed and draw rolls 2 to 6 times its original length at a draw rate of at least 75,000% per minute, preferably between 75,000 and 550,000% per minute. Preferably the film is at a temperature of 90‹ to 140‹ C. at the time it is drawn, and if quenched after extrusion to a temperature below 90‹ C. is reheated prior to drawing, which may be effected by passing it over a fast draw roll having a peripheral speed of between 90 and 1200 feet per minute, and a surface temperature of below 120‹ C., suitably no higher than 40‹ C. Uniaxially oriented film so produced may be drawn in the transverse direction to obtain a biaxially oriented film. In apparatus as shown, a polypropylene melt is extruded into contact with the surface of a cylindrical internally cooled casting drum 2 and passes over idler roll 6 on to cylindrical feed roll 3 which may be internally heated and which rotates at a peripheral speed substantially that of the drum 2. The heated film then passes to draw roll 4 which desirably has internal cooling means and which rotates at 2 to 6 times the peripheral speed of roll 3, roll 4 being located sufficiently close to roll 3 that the draw span, or tangential distance of film between the rolls, is short enough to achieve the required draw rate, and is then conveyed to the wind-up roll 5. In examples, using a take-up speed of 100 ft. per min., a draw rate of 300,000% per min. and 6 ins. diameter feed and draw rolls, the distance between the rolls must be 0.082 ins. while using a take-up speed of 400 ft. per min., a draw rate of 75,000% per min. and 12 ins. diameter draw rolls, the distance between the rolls must be 1.4 inch.
