Title: Improvements in or relating to navigation aiding radio transmitting installations
IPC: G01S1/02
Filed: 1937-08-20
Abstract: 483,449. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Aug. 20, 1937, No. 22905. Convention date, Aug. 20, 1936. [Class 40 (v)] Relates to wireless transmitters of the overlapping- beam type in which two dipoles are bached by a common reflector and fed from the same H.F. source through branched feedlines. The invention consists in means for matching the dipoles to their feeders, and for preventing undesirable reaction between the feeders and aerials during periods when the latter are short-circuited, i.e. when producing divergent beams. If the dipole 11, Fig. 2, is connected to the feedline 10 at a point where it forms a capacitive load, this is counterbalanced by a variable " trombone " inductance 13. In Fig. 4, the surge impedance of the feeder 18 is represented by the straight line 20, and the resistance of the aerial 19 by the curve 21, and matching is secured by inserting an inductance at L or a capacity at C. In Fig. 5, the two dipoles 22, 23 are backed by a reflector P and fed from a common source S. The short - circuiting necessary to produce two diverging beams is effected at the points 24, 25, situated an odd number of quarter wavelengths away from the branching point 26, preferably by shunting the feeders by a timed circuit, the impedance of which can be varied from zero to infinity.

Title: Magnetic recording
IPC: G11B7/125
Filed: 1967-05-19
Abstract: 1,141,119. Magnetically recording binary information. INTERNATIONAL BUSINESS MACHINES CORP. 19 May, 1967 [7 July, 1966], No. 23286/67. Heading G5R. A system for magnetically recording binary information comprises a thin film of a ferromagnetic rare earth chalcogenide, means for maintaining the film at a temperature below its Curie temperature, means for applying a magnetic bias field to the film in a direction representative of the information required to be recorded, and means for lowering the coercivity of a selected area of the film, the magnetic bias field being sufficient to establish magnetization in the representative direction in the selected area but insufficient to alter the magnetic state of the remainder of the film. As shown, a thin film 4 (e.g. 300 to 10,000 Š thick) of EuO is deposited or formed on glass or like transparent substrate 2. A winding 16 has current, sufficient to apply a saturating magnetic field, passed through it, the field being stored in the EuO film in the direction of arrow 18, or the "0"-direction. The surrounding container 26 is heat-insulated and the contents are maintained at a temperature of 25‹ K. A housing 6, containing a source of laser light, preferably in the form of a gallium arsenide laser, a focusing lens 10, a polarizer (not shown) and a conventional deflecting apparatus 14 are provided. For writing a " 1 ", current is sent through a winding 20 to apply a field 22, opposite in direction to field 18 but insufficient to reverse it. Then co-ordinate signals are applied to deflector 14, so that when the laser source 6 is pulsed (at the same time or just after this), the beam is directed at a chosen spot 12 (eg. of five microns diameter). The spot 12 is thereby heated: (temperature rise, e.g. 30‹ C. in e.g. nanoseconds), the temperature being slightly below or above the Curie temperature. The coercivity of spot 12 is thereby lowered (e.g. by a factor of 5), permitting the magnetic field 22 to become effective to reverse the field direction at spot 12. When the laser pulse is terminated a " 1 " has thus been recorded. For readout the laser is pulsed with, e.g. one fiftieth of the " writing " pulse. The plane of polerization of the beam thereby transmitted through spot 12 undergoes Faraday rotation; the beam is received by a photodetector 24 which incorporates an analyser and is connected to a utilization circuit 28. The photodetector 24 may be located to receive reflected light.

Title: Improvements in the manufacture and production of acetylene
IPC: C07C4/02
Filed: 1930-08-05
Abstract: In the manufacture of acetylene from gaseous or volatilized hydrocarbons or gases containing such hydrocarbons, in the electric arc, the gases are treated in a preheated state, their heat content being derived from a preceding chemical conversion at an elevated temperature of part of the same gases, and the gases leaving the arc are cooled down as quickly as possible ("chilled").  Preferably the initial gases have an appreciable content of hydrogen, e.g. up to 50 per cent of their hydrocarbon content.  The acetylene obtained is particularly suitable for further conversion, e.g. into acetaldehyde, owing to its freedom from impurities.  In examples: (1) a gas mixture containing methane is passed through a Cowper apparatus in which it is converted into a mixture of approximately equal parts of methane and hydrogen, with formation of carbon black; the mixture passes via a carbon black separating vessel to an electric arc furnace and thence to a cooling apparatus; (2) methane is subjected to partial combustion with oxygen and the resulting hot mixture of carbon monoxide and hydrogen is mixed with more methane and passed through an electric arc furnace and thence to a cooler; (3) a gas containing methane is passed through an arc for the production of carbon black and thence via a carbon black separating chamber to a second arc for the production of acetylene, the gases leaving the second arc being chilled; (4) a gas mixture containing methane, ethane and propane is passed through an arc producing carbon black, unsaturated hydrocarbons and acetylene, and thence to a heat exchanging chamber and a carbon black separating chamber; after passing a washing tower in which the acetylene is removed by means of a suitable solvent, e.g. acetone, the gas (now mainly methane and hydrogen) is passed again through the heat exchanger, where it is heated by the gases from the first arc, and finally to a second arc for the production of acetylene, the gases leaving the second arc being chilled.  According to the Provisional Specification the preceding chemical conversion may also be one by which the initial hydrocarbons are formed, e.g. the hydrogenation of a gas mixture containing carbon monoxide.
