Title: Improvements in or relating to apparatus for the manufacture of metallised paper forelectric condensers
IPC: H01G13/06
Filed: 1945-06-29
Abstract: 595,808. Condensers. HUNT, Ltd., A. H., and GROUSE, R. A. June 29, 1945, No. 16642. [Class 37] In apparatus for demetallizing portions of metallized paper, such as in Specification 563,080, wherein a demetallizing discharge takes place between one or more contact discs 31 and the metal coating on the paper 38, each contact is in parallel with a condenser 33, the contact and condenser being connected in circuit with a resistance 30 which extinguishes the discharge without permitting it to spread irregularly from the contact, but allows adequate current to charge the condenser between the intermittent discharge periods. The metallized paper 38 is passed continuously and in contact with the demetallizing discs, each discharge volatilizing the metal for a given distance ahead and on each side of the disc, the condenser being recharged during the interval before the arrival of the metallized surface again. Charging and discharging take place in rapid succession thereby increasing the speed of demetallizing and giving a smoother line of demetallization. Each contact disc is preferably associated with a separate resistance and condenser, though the contacts may be grouped and a single resistance or capacitor or both allotted to each group. The demetallizing discs 31 are mounted on a common spindle 99, Fig. 4, driven through gears 106, 120 and may be collectively lifted away from the paper 38 (so that the condensers may gain an initial charge) by rotating about a spindle 83. Adjustable screws (not shown), resting on supporting plates at each end of the spindle enable the pressure between paper and discs to be adjusted. Further adjustment is provided by a roller 36 pivoted in blocks 76 sliding in slots 77 in end plates 71, the blocks being supported by springs 78 and adjusted by screws 79. The discs are insulated from each other and from the spindle 99 and each disc is associated with a slip ring to which connection is made through a brush 113 and arm 110 pressed against the slip ring by a spring 114. Any contact disc may be separately cut out by rotating the arm 110 rearwardly through 90 degrees so that the corner snaps past the spring. The spindle 83 is screw-threaded at one end and carries a hand wheel 85 by means of which it may be moved longitudinally. Suitable values for the condensers, resistances, voltage &c. are given. Specifications 483,029 ; 485,965 and 513,257, [both in Group II], also are referred to.
