Title: Treatment of plastic materials to increase their adhesive capacity to inks and colours
IPC: B29C59/10
Filed: 1956-12-28
Abstract: A method for the treatment of plastic material to increase the adhesive capacity of inks and colours thereto consists in passing the material to be treated through a high strength electric field, the field being a high frequency oscillatory field in the frequency range 8,000-500,000 cycles per second.  An A.C. power source supplies a transformer, the secondary of which is connected to two rectifying valves or selenium rectifiers, a capacitor levelling the current.  A second system of transformers supplies a self-oscillating system including a triode, whose grid circuit includes a variable resistor. The self-oscillating system is completed by a transformer including two coupled and calibrated windings, and whose high-voltage secondary is connected to two pairs of electrodes, between which is passed the strip to be treated.  A dielectric is inserted between the strip and two of the electrodes.  The intensity of the field is adjusted by the resistor according to the thickness and speed of the strip and the intensity of treatment required.  In another form, hollow tubes are placed on spindles mounted around a table of insulating material rotated by a motor and vertical shaft.  Carried on a support assembly is an element having a plurality of slidable stems supporting a slide block urged towards the shaft by springs. The block is connected to one side of the electric supply and extends along nearly half the path of the spindles, each spindle contacting and being rotated by the block during that part of its path, and thereby constituting one electrode.  The assembly also carries slide blocks which contact the tubes and rotate them. Between the blocks is mounted the second electrode, which carries a dielectric and is circumferentially co-extensive with the block. Each tube is thereby treated several times over its circumference during its passage between the electrodes.  The tubes are removed and replaced on the remaining part of their passage, manually or automatically, as by jets of compressed air.  The spindles are of a cross-section to fit the articles to be decorated.  The table may be replaced by an endless chain conveyer. The second electrode may be adjustable relative to the spindles.

Title: Film-spool drive in cinematographic equipment
IPC: G03B1/56
Filed: 1973-08-21
Abstract: 1423209 Driving film spools BOLEX INTERNATIONAL SA 21 Aug 1973 [8 Sept 1972] 39634/73 Heading G2E Film handling apparatus for preventing tension in a film between a film gate and spool exceeding a predetermined value comprises a film gate 26, a film spool e.g. supply spool 3 mounted on a support 7 upstream of the film gate, the support and spool being displaceable between a second (undriven) position (shown) and a first (driven) position against the bias of a spring 14; the displacement of the spool and support is produced by tension in the film between the spool and the gate and causes the spool to engage a drive to rotate the spool and relieve the film tension; alternatively if the spool is downstream of the gate e.g. spool 4 mounted on support 8, the support is normally in the first (driven) position so that the spool acts as a take-up, any excess tension in the film is relieved by the support moving to the second (undriven) position. The drive comprises a continually driven shaft 1, a belt 2 and pulleys 20,21. The pulleys each have a boss 18, 19 on which are mounted rubber rings 32,33. The spools 3,4 have annular troughs 16, 17 and are driven by the rubber rings engaging either the inner or outer walls of the troughs. The lever 7 is biased by spring 14 to a position in which ring 32 does not engage either of the trough walls, therefore unwind spool 3 is not driven. If tension occurs in the film between spool 3 and gate 26 the spool and lever are pulled from right to left, lever 7 pivoting about pin 9, so that ring 32 engages the inner trough wall and drives the spool to unwind the film. As soon as the tension is relieved lever 7 returns to its initial position under the influence of spring 14. The take-up spool 4 and lever 8 are biased by spring 15 to engage the drive. If the film tension exceeds a predetermined value lever 8 pivots about pin 10 and disengages the drive. If the tension is sufficient the spool moves until ring 33 engages the inner trough wall and drives the spool in an unwind direction. To reverse the function of the spools a bar 11 on which the levers 7 and 8 are mounted is pivoted about a fulcrum 25 against the bias of spring 24 by energizing an electromagnet 22. In an alternative embodiment each spool has two associated driven pulleys, each spool being driven forwards or backwards by engaging the pulley hubs.

Abstract: 828,730. Electric measuring systems. GENERAL ELECTRIC CO. Ltd. Dec. 31, 1957 [Dec. 31, 1956], No. 39666/56. Class 40 (1). [Also in Group XXXVI] Apparatus for measuring the gravimetric rate of flow of a fluid comprises a dynamometer instrument, the moving coil of which is supplied with current proportional to the volumetric rate of flow of the fluid, and the fixed coil(s) of which produce(s) a magnetic field proportional to the density of the fluid. As shown, the volumetric rate of flow of petrol in a pipe 3 of an aircraft fuel system determines the frequency of the output of a pulse generator 1 which comprises a turbine wheel 2, carrying a bar magnet 4 and mounted in the pipe 3, and a pick-up coil 5 located outside the pipe adjacent the turbine 2. The pulses from generator 1 are amplified at 6 and passed to a frequency discriminator 7, the output I of which is fed to the moving coil 12 of an iron-cored dynamometer 11. The dielectric constant, K, of the fuel is sensed by using the fuel as the dielectric of a capacitor 9 which is connected to an A.C. voltage generating and rectifying circuit 10, the output I 2  of which is applied to a fixed coil 13 of the dynamometer 11. Since the density of petrol equals BK - C, where B and C are constants, and as K=EI 2 , where E is the constant of proportionality, the field due to I 2  is modified by supplying a current I 3 , equal to C/BE, from a source 15 to a second fixed coil 14 of the dynamometer 11, so that indication may be given directly in gravimetric units.
