Abstract: 1,054,231. Volatile metal chlorides. B. R. HOLLEBONE and D. R. WILES. Jan. 1, 1965 [Jan. 2, 1964], No. 124/65. Heading C1A. [Also in Division C2] A process for the separation of volatile metal chlorides of Group IV, V, VI from their ores or other materials by treating the ore or material with molten pyridine chloride in quantities sufficient to effect stoichiometric conversion to the corresponding chlorides and to dissolve the soluble reaction products, at a temperature between the melting point of pyridinium chloride and the boiling point of the solution, for a length of time sufficient to dissolve an appreciable fraction of the metal, allowing water, pyridinene and unwanted volatile products to escape, and heating the solution in vacuo or under a slight pressure of hydrogen chloride at 160-180 C. to drive off pyridine chloride and finally heating the residue in vacuo at 180- 400 C. to complete sublimation of metal chlorides. The ore or material may be previously treated by an alkaline fusion and this step may be repeated on any ore or material remaining undissolved in the pyridine hydrochloride. The volatile metal chlorides may be separated and purified by conventional methods. The ores include ores of niobium, tantalum, molybdenum, tungsten, zirconium, ferro-niobium. The step of treating the ore or material with pyridine chloride should be carried out with agitation.

Abstract: 1,253,157. Oscillators. WESTERN ELECTRIC CO. Inc. 10 Dec., 1969 [11 Dec., 1968], No. 60266/69. Heading H3T. High-frequency power generation apparatus includes a plurality of oscillators coupled in progression so that each provides a synchronized contribution to the total output: each oscillator includes an oscillation source and at least one oscillator is adapted to combine the oscillations from its source with oscillations from a preceding oscillator and to provide to the next oscillator coupled to it a synchronizing signal to synchronize the source therein and a separate signal for combination with the output of the latter. Each oscillator comprises an oscillation source, e.g. 10, which receives a synchronizing signal from an input port, e.g. B1 via a three-port circulator 11 at the third port of which appears an output which is applied to one input port of a first 3dB directional coupler 15. A further input is received on a second input port, e.g. B and is fed to the second input port of the first 3dB directional coupler 15 via a path 13 of the same electrical length as that through circulator 11. The output ports of first 3dB directional coupler 15 are coupled to the respective input ports of a second 3dB directional coupler 19 via paths 16, 17, the second of which includes an adjustable phase-shifter 18, whereby the ratio between the outputs at the two output ports of 3dB directional coupler 19 can be adjusted. The input ports of the first in the progression of oscillators are fed from a driving oscillator 1 via 3dB directional coupler 3, in one of whose outputs is an adjustable phase-shifter 4: the second input port A of 3dB directional coupler 3 is terminated as a dummy load 2. Each subsequent oscillator receives its two inputs from the outputs of the second 3dB directional coupler in the preceding oscillator. In the final one output port feeds the load and the other a dummy load 6, the phase-shifter being adjusted to direct all the output power into the load. The circulators may be replaced by hybrid junctions, and three-port circulators having adjustable short-circuits may be used instead of phase-shifters.

The surface irregularities of a body 2 Fig. 1 are sensed by a stylus 1 and converted by transducer 3 to a voltage signal whose alternate half-cycles are fed to capacitors C 11 , C 12  via switches 8, 9 controlled by a phase-sensitive discriminator 7. In alternate half cycles, the stored signals are transferred to capacitors C 21 , C 22 . A limiter 10 ensures that the maximum voltage change after operation of switches 8, 9 does not exceed an adjustable value U 13 , whereby an excessive irregularity cannot produce a signal greater than U 13 . Each capacitor C 11 , C 12 , C 21 , C 22  may be associated with a resistor to produce a time constant causing the network to reject regularly recurring irregularities. The algebraic sum of the voltages as capacitors C 21 , C 22 , representing the maximum peak-to-valley variation, is indicated on meter 11.

Abstract: 1,264,862. Repeaters. WESTERN ELECTRIC CO. Inc. 10 March, 1969 [11 March, 1968], No. 12411/69. Heading H4R. [Also in Division H1] In repeater apparatus utilizing both D.C. (power) and A.C. (signal) currents, different return paths are provided for the said currents and one or more filter sections used to isolate the two paths and thereby prevent signal feedback. As shown, D.C.. power and signal frequencies are fed through the same conductor 11 to a communication-cable repeater 14 (which may be a two-way device). Amplified signals and D.C. power are fed to a similar common output line connected to a load 35 e.g. another repeater. The D.C. current passes from the input line through L-section filter 25, isolators 28, 31 and L-section filter 32 to the output line. A stabilized voltage, e.g. 12 V., for operation of the repeater 14 is derived across a pair of zener diodes 29, 30. The return path for the D.C. current consists of an outer casing 12 which thus constitutes a D.C. earth. The A.C. signals pass through isolating capacitors 27, 34 and the return signal path is constituted by the internal surfaces of the coaxial line sections and of inner casing 13 in series with further isolating capacitors 40, 41. The return spiral current is indicated by the arrows i L . Because of the finite reactance of these capacitors, a certain proportion of the A.C. return current tends to flow along the outer surfaces of the input and output coaxial line sections and along the inner surface of the outer casing 12. This current is indicated by the arrow i F . The addition of capacitor 46 does not entirely suppress this current. To completely eliminate the current, ferromagnetic rings 48, 49, 50, 51, 75, 76, 77, 78 and additional capacitors 45, 47 are disposed as shown to form, in effect low-pass filters providing a low impedance path for the A.C. return current i L .
