Title: Process and apparatus for the Manufacture under pressure of Gases which may be substituted for Natural Gases
IPC: C10G/
Filed: 1967-07-25
Abstract: 1,170,304. Combustible gas. GAZ DE FRANCE. 25 July, 1967 [26 July, 1966], No. 34111/67. Heading C5E. Combustible gas, exchangeable with natural gas, is made under pressure by (a) cracking liquid and/or gaseous petroleum hydrocarbons on a weak catalyst, e.g. refractory oxides or silicon carbide, in the presence of steam, (b) purifying the basic gas produced, and (c) subjecting the purified gas to an auto-hydrogenation with a catalyst which includes a metal of the platinum group; said cracking being performed alternately and successively in at least two series of reactors in one of which the cracking is carried out whilst simultaneously in the other series of reactors the used catalyst is regenerated by means of air and steam at the same pressure as that employed for cracking and the gases resulting from the regeneration being added to the cracked gas to obtain the basic gas, the autohydrogenation of which is carried out, after cooling, at the same pressure as that used for the cracking. In a modification the amount of air added during the regeneration phase is such that the gas leaving the regeneration reactors contains about 10 volume per cent of nitrogen and this gas is fed to the burners for heating the cracking and regeneration reactors. In the purification step (b) H 2 S is removed from the gas by passage through granulated iron oxide or zinc oxide, before this purification the gas may be washed with a liquid petroleum fraction. The effluent from the auto-hydrogenation reactor is recycled after cooling to the inlet of this reactor, alternatively a reactor having an internal cooling circuit can be used.

Filed: 1933-12-06
Abstract: 430,161. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, DOWSETT, H. M., 47, Drayton Gardens, Winchmore Hill, and WALKER, L. E. Q., 98, Wymering Mansions, Maida Vale, all in London. Dec. 6, 1933, No. 34301. [Class 40 (iii)] The band-width in television-transmission is reduced by heterodyning the picture signals (consisting mainly of the line frequency and its harmonics) with an oscillation rich in harmonics and of slightly different frequency. The resulting frequency band comprises a fundamental and harmonics equal to the difference frequencies, the highest of which is arranged to be less than the fundamental line frequency. At the transmitter the picture signals and the local oscillation and harmonics are passed through a square-law rectifier or demodulator (i.e. one whose output current is a quadratic function of the input voltage) which yields the required narrow band of frequencies. At the receiving station this band is heterodyned with a local oscillation of suitable wave-form by means of a detector having a square-root law. The signals are thus translated back into their original form.

Abstract: 625,067. Radio signalling ; radio receiving systems ; diplex radio signalling. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 22, 1946, No. 34730. Convention date, June 12, 1943. [Class 40 (v)] In a signal receiver for carrier-wave telephony systems in which the carrier is suppressed during speech, but is used for transmitting the call signals, the call-signal oscillations Vp are applied in the same sense to the rectifiers of each of two oppositely connected pairs 4, Fig. 3, of biassed rectifiers while an auxiliary oscillation Vq of constant amplitude is applied in the opposite sense. By this arrangement the call signal oscillations are converted into output oscillations of reduced frequency and constant amplitude for ensuring reliable operation of the call relay. Instead of providing negative bias for the rectifiers, as shown in Fig. 3, the bias may be dependent upon the current flowing through the call relay 11, Fig. 6, the bias being derived from a resistance 15, 16 included in the anode circuit of an amplifying valve 10 following a detector 9 and filter 8.
