Abstract: 1304831 Photo-electric apparatus ELTRO GmbH 25 May 1962 [25 May 1961] 20300/62 Heading G1A [Also in Division H4] The position of a point target relative to a reference direction is determined by a device which modulates the acoustic or electro-magnetic waves emitted by the target; the depth and phase of the modulation is determined by the target angular position with respect to a line of sight. As shown, the target radiation is received at the focusing device 3 and the resultant beam is directed into the deflecting device 9 so as to displace it laterally with respect to the aiming axis 5. From device 9, the beam passes to the modulator disc 10 which is formed with alternate, radial, opaque and transparent segments. The disc remains fixed while the deflector 9 rotates at a fixed angular velocity round axis 5 and produces due to its eccentricity of orbit a frequency modulated signal. A photo-electric cell may receive the modulated beam transmitted by disc 10, and the output after comparison with a reference frequency, is rectified and demodulated to produce from the amplitude and phase of the F.M. two D.C. voltages which represent the Cartesion Co-ordinates of the target. The system is said to be adaptable to radar, infrared, optical, ultraviolet, or acoustic waves.

Title: Purification of hydrogen
Inventor: CHARLESWORTH PAUL LANE
IPC: F25J3/06
Filed: 1964-05-19
Abstract: In a process for purifying H2 by condensing out CH4 impurity, the f.p. of the CH4 is depressed by at least 1.5 DEG  K, preferably 3-5 DEG  K, by the presence of C2H6, C2H4, C3H8 or mixtures thereof and the impure H2 is cooled below the f.p. of pure CH4 (90.7 DEG  K) but above the depressed f.p. under a superatmospheric pressure (10-50 atm.) such that more hydrocarbon is condensed out and substantially pure H2 is separated from the condensate.  The feed gas may be refiner or reformer off-gas containing H2O, C1-C5 alkanes and possibly C2H4, in which case the water and the butanes, pentanes and preferably propane are removed in one or more preliminary drying and condensation steps.  Preferred components for depressing the f.p. of CH4 are ethane, in amount 2-33 molar per cent of total CH4 plus C2H6 content, or ethylene, in amount 5-13%.  These hydrocarbons may be added to the H2/CH4 mixture when it is initially free of other hydrocarbons. N2, CO or other impurities boiling below the f.p. of the hydrocarbon mixture will not be separated by the process of the invention but their presence does not affect the removal of CH4.  The cooled uncondensed gas and condensate are used to cool incoming gas by indirect heat exchange in one or more stages, the condensate being expanded to a lower pressure (about 1 atm. abs) before the final heat exchange and to which may be added thereafter pure or impure H2 in amount 2-4%.  A closed N2 refrigeration cycle is used for cooling, and additional cooling is provided by expansion of the purified H2 with performance of external work and indirect heat exchange with the impure H2.
