Abstract: 523,044. Optical sound-reproducing apparatus. PHILIPS LAMPS, Ltd. June 26, 1939, No. 18566. Convention date, June 28, 1938. [Class 40 (ii)] In photo-electric sound-film reproducing apparatus, for scanning either a push-pull sound-track or a " simple " sound-track, changing from one type of scanning to the other is effected by merely substituting a doublecathode cell for a single-cathode cell (or vice versa), the optical system remaining unchanged. The necessary modification in the circuit connectiohs is made solely by the alteration of the photo-electric cell. Fig. 2 shows apparatus for reproducing a push-pull record, light passing through each half 35, 36 of the sound-track being directed by a prism 13 or 14 on to the respective cathode 38 or 39 of a double-cathode cell 37. The cell has four pins 41 ... 44 which engage in holder-terminals 22 ... 25. These are connected in the input circuit of an amplifier 34 as shown, the terminals 23, 24, which connect with the anode 40 of the cell, being joined together. There may be two anodes, each connected to a pin 42 or 43. For use with a film having a simple sound-track 11, Fig. 1, a singlecathode cell 16 is substituted for the cell 37. The connections of the terminals 22... 25 with the amplifier remain unchanged, and the cell 16 has the same arrangement of pins as the cell 37, but in this case the terminal 25 is ineffective, only one half of the transformer primary winding being used. The prisms 13, 14 transmit the whole of the modulated light to the cathode 15. The arrangements may be modified for resistance coupling to the amplifier.

Abstract: Nickel is separated from solutions containing it and cobalt, and possibly other metals such as iron, zinc, manganese, copper and lead, by treating the solution with compounds of iron with sulphur, arsenic, antimony, selenium or tellurium, which compounds are added as such or produced in the solution.  Thus, there may be used iron sulphide or arsenide, metallic iron and elemental sulphur, iron sulphide and iron, or iron and sulphur dioxide, arsenic trioxide or pentoxide, selenium dioxide &c.  The iron sulphide used may be made by a wet process, or by smelting, and containing in this case an excess of iron.  Metallurgical by-products such as speiss &c. may also be used.  The nickel and cobalt may be present as sulphates or chlorides, but not as nitrates, when the metallic iron would be oxidized to the trivalent state.  The reaction may be effected from below 90 DEG  C. to the boiling point, and at a pH of 1-5.5.  Cobalt, iron, zinc and manganese remain in solution; nickel, copper and lead are precipitated.
