Patent ES-372802-A1 (ES)
Title: Preparation of Films of Polypivalolactone
IPC: B29C48/08
Filed: 1969-10-23
Abstract: Polypivalolactone films are made by meltextruding the polymer into air through a die having a longitudinal slot extrusion orifice, drawing out the extruded melt at a drawdown ratio between 5 :1 and 500 :1 (preferably between 10 :1 and 200 :1) to form a film which is rapidly cooled to a temperature below 150 C., preferably below 100 C., in a sufficiently short time to produce a transparent film. The solidified transparent film is then stretched in one or more directions at a temperature between 20 and 200 C. (preferably between 125 and 200 C.) at such a stretch ratio that the elongation at break of the film after stretching, measured in the direction(s) of stretching and at room temperature is 10 to 200%, preferably 40 to 80%. The film is then annealed at a temperature between 110 and 220 C., preferably between 150 and 200 C., without applying stretch. The film may be allowed to shrink freely or to a certain extent, but is advantageously kept at a constant length during the heat-setting or annealing step. Thereafter the film is further stretched in one or more directions at a temperature between 100 and 220 C. and at a stretch ratio such that the elongation at break of the film after stretching, measured in the direction(s) of stretching and at room temperature is between 5 and 70%. In the example, a polypivalolactone having an intrinsic viscosity (determined in benzyl alcohol at 150 C.) of 1À10 decilitres per gram is melt-extruded at 285 C. through a die having an extrusion slot 15À7 mm. long and 0À2 mm. wide to form a film which is cooled and solidified by being passed through water at 15 C., the level of the water being 5 cm. below the die. The film is taken up at a speed of 6 m/min. and the draw-down ratio applied to the film during its passage from the die to the take-up roll is 26À5 : 1 (draw-down ratio 26À5:1). The clear 30 micron thick film obtained is stretched longitudinally at a temperature of 175 C. and a stretch ratio of 4 : 1 which imparts to the film elasticity and an elongation at break of about 70% when further stretched longitudinally at 175 C. The film is heat set at 180 C. for 8 minutes while held at constant length and is then stretched again at 185 C. and a stretch ratio of 1À5 : 1 whereby there is imparted to the film an elongation at break of 15% and a shrinkability of 35% at 180 C. By subsequent heat relaxation of the film at 180 C. free of tension the elongation at break of the film is increased to about 70%.

Title: Circuit arrangement for use in a television camera tube with an anti-comet tail electron gun
IPC: H04N5/228
Filed: 1974-03-11
Abstract: An automatic control to the optimum lens adjustment in an ACT gun in a television camera tube. A variation in the cathode and control electrode potential during the line flyback requires an adaptation of the lens voltage for optimum target erasing action. In the circuit a measurement of the anode current in the gun is effected because for an optimum target erasing action during the line flyback it is found that this current must be at a minimum. A measurement is effected about an adjusting point. In case of unequal current the optimum value is not yet reached and an adjusting point displacement is effected towards the optimum value whereafter a subsequent measurement is effected.
