IPC: H01S1/02
Abstract: 1,036,143. Semi-conductor devices STANDARD TELEPHONES & CABLES Ltd. April 26, 1963, No. 16559/63. Heading H1K. [Also in Division H3] Infra-red or microwave signals are amplified by an N-N+ semi-conductor, the two regions of which have g-factors of opposite sign, the semi-conductor being connected to a D.C. source and located at low temperature in a magnetic field. The sign (+ ) or (-) of the g-factor determines into which of the Zeeman sub-levels electrons having one or the other possible spin orientations will go, electrons with spins parallel to the applied magnetic field going into the upper level when the g-factor for a region is positive, and electrons with anti-parallel spins going into the upper level when the g-factor for a region is negative. At the operating temperature, the lower energy levels have the greater population. When a direct current is passed through the junction between the two semiconductor regions the oriented electrons passing across the junction from one region to the other are transposed, those in the lower energy level being raised to the upper level and vice versa. Inversion of population is therefore obtained, and an applied infra-red or microwave signal of the appropriate frequency determined by the population-inverted sub-level spacing is amplified by stimulated emission processes. For an infra-red amplifier, Figs. 1 and 2 (not shown), the semi-conductor material may be indium antimonide doped with an N-conductivity type of impurity such as antimony, phosphorus or arsenic; the region 2 from which electrons are drawn being heavily doped so as to have near-metallic properties and a g-factor equal to + 2, which the region 3 into which the electrons pass and are transposed is lightly doped with the same impurity and has a g-factor equal to - 58. Other suitable semi-conductor materials are indium arsenide, gallium arsenide, mercury telluride, mercury selenide, bismuth and antimony. For a microwave amplifier, Figs. 3 and 4 (not shown), the same impurity is again used for both regions, the semi-conductor material being gallium arsenide. In this arrangement, region 2 is heavily doped and has a gfactor of + 2, while region 3 is lightly doped and has a g-factor of -1À6. With the exception of the semi-conductor bodies the embodiments are identical to those described in Specification 986,589.

Abstract: 1,052,823. Extracting iron. ARMCO STEEL CORPORATION. Feb.11, 1964, No. 5664/64. Heading C7D. Finely divided iron ore is reduced in a fluidized bed reactor, the tail gases from the reactor passing to a gas cooler where moisture is removed and from there to an ore cooler, a part thereof being subsequently used as fuel to preheat the ore charge while the remainder is used as fuel elsewhere in the process. The reducing agent may be natural gas, which is first treated in a steam-methane reformer, cooled to reduce its moisture content and then reheated prior to use, the reformer and reheater being fired by tail-gas from the reactor. A suitable arrangement of apparatus is shown diagrammatically in an accompanying drawing (not shown). Fluxes, such as limestone, may be charged with the ore, while by suitable control of the conditions in the reformer, preheater or reactor the reduced ore can be caused to have a carbon content up to 8%.

Abstract: 1,054,020. Frequency changing. SIEMENS & HALSKE A.G. Sept. 29, 1965 [Sept. 30, 1964], No. 41294/65. Heading H2F. A frequency multiplier suitable for wavelengths of the centimetric region and having a multiplication factor greater than 3 and not greater than 10 comprises a varactor diode used as a non-linear element, an input band filter tuned to the fundamental frequency, an output band filter tuned to the desired harmonic output, and a number of auxiliary circuits exhibiting series resonance for all the harmonics between the fundamental frequency and the desired harmonic provided across the varactor diode to short circuit these unwanted harmonics. An auxiliary circuit for the next higher harmonic and further higher harmonics may also be provided. As shown in a 6-times multiplier series-tuned circuits for the 2nd, 3rd, 4th, 5th and 7th harmonics are provided across a varactor diode D, and are disposed in star formation in screened compartments in a metal housing. The inductors are connected to the diode. In a further embodiment transmission line sections are connected across diode, each of these providing series resonance for a number of the unwanted harmonics so that the number of components is reduced. A plurality of multipliers may be connected in cascade to provide a frequency multiplication greater than 10.

Abstract: 1,143,805. Vacuum switches; actuation of switches. ENGLISH ELECTRIC CO. Ltd. 1 Aug., 1967 [4 Aug., 1966], No. 34928/66. Heading H1N. Actuating mechanism for a vacuum switch or other device includes a magnetic coupling comprising an actuator rod 15 having an armature 14 whose face 14A is engaged by a linearly movable cam driven magnetic core element 11 and held in engagement therewith by energized coil 12. In operation a motor 23 rotates a cam 22 to allow the element 11 to move initially downward under the bias of gravity and/or springs 24. If the coil 12 is energized when faces 11B and 14A come into engagement, the actuator rod 15 moves with the element 11 as the revolution of the cam 22 is completed, so that contacts 8, 9 of a vacuum switch 10 are closed. The contact 9 and actuator rod 15 are biased by springs 26 acting on a cross-bar 25 on the rod 15 and release is effected by deenergization of the coil 12 or by energization of an opposing release coil 13. The vacuum switch may have resilient contacts with or without the biasing springs 26.
