Abstract: 683,931. Making compound foil. NATIONAL RESEARCH CORPORATION. Feb. 2, 1951, No. 2585/51. Classes 83 (ii) and 83 (iv). [Also in Group XXXVI] A plurality of electrodes moving in one direction engage successively the metal coating on a non- conducting web moving in the opposite direction which is at a different potential to the electrodes, thus creating an arc therebetween which removes metal from the web to form a metal free stripe. Paper coated with zinc 24 is advanced over guide rollers 20, 21, 22 and rolled upon a roll 14 by means of a roller 42 driven by a motor 44 which also drives a shaft 29 carrying two wheels 28 supporting radial electrodes 26. The electrodes are connected in turn by a contact 30 to one side of a battery 36, the other side being earthed to complete a circuit through the metal 24 by way of the earthed rollers 20, 22. The contact 30 is arranged so that one electrode 26 is deenergized prior to losing contact with the metal 24 when the next is energized. The arc struck between each electrode 26 in contact with the metal 24 removes metal therefrom and deposits it on the knife-edged electrode from which it is removed by a motor-driven brush 38. The paths of the web and electrodes are such that contact between them results in only slight deviation of the web path. The contact 30 may be employed for both wheels 28, being located between them. Specification 563,080, [Group XXXVI], is referred to.

Title: Method of producing rubber heels
IPC: B29D35/12
Filed: 1958-01-27
Abstract: 869,571. Moulding rubber heels. SEIBERLING RUBBER CO. Jan. 27, 1958 [Feb. 5, 1957], No. 2605/58. Class 87(2). [Also in Group VII] A nailable, nail-retaining plastic core for a heel is temporarily supported above the surface of a heated mould, before filling the mould cavity with a vulcanisable rubber composition, after which the rubber composition is at least partially vulcanised and bonded to the core. In the mould shown in Figs. 1 and 3, the core 5 is supported on at least three pins 12 arranged about the boss 3 projecting from the back plate 10 and a vulcanisable rubber biscuit 15 is placed over the core. When the face plate 14 of the mould is lowered into position, the biscuit and core are forced into the mould cavity with the pins forming depressions in the core. The advantage of this method of moulding is that the core does not melt prematurely. Various other means may be used to support the core and in some of the arrangements described, the opening in the core is sufficiently small for the core to be supported by the boss. Different types of bosses are shown and the different means for supporting the core are interchangeable with the different types of boss. The opening in the core may be slightly smaller than the boss, the corners of which are raised with tapered lugs which serve to support the core. In similar constructions, the core may be supported by projections or on a recessed ledge around the boss. The pins 12 of an alternative mould, (Fig. 10 (not shown), are supported by springs so that when pressure is applied, the pins are pushed downwardly until their tops are level with the lower surface of the mould cavity. In order to avoid the use of pins the wall of the core is not sheer but has a bevelled edge 43, Fig. 16, which rests on the boss 3. If a mould having no boss is to be used, two sets of pins may extend upwardly from the back plate 10, Fig. 18, the taller pins 61 serving to space the core away from the walls of the mould cavity and the shorter pins 12 to support the cores off the bottom of the mould, The core may be made of either a thermosetting or a thermoplastic material, preferably the former since it is hot when removed from the mould cavity and if a thermoplastic is used it is apt to be deformed on removal and to be permanently misshapen by being cooled in this deformed condition.

An adder 21 adds the amplitudes of the separated pulses to provide an automatic gain control signal for AGC amplifier 11. As shown, generator 15 is a free running multi-vibrator. The signals on each track of the record medium consist of transitions of alternating polarity between two states of magnetization, the transitions of one polarity being coincident along the two tracks and the transitions of the opposite polarity being spaced at different fixed intervals on their respective tracks to provide the intermediate pairs of pulses. An embodiment with three adjacent tracks is described, Figs. 7-12 (not shown) with logic circuitry for determining which adjacent two tracks the transducer is following.
