Title: Process for the production of combustible gas enriched with gaseous hydrocarbons
IPC: C01B3/26
Filed: 1953-02-09
Abstract: 792,914. Fuel gas. GAS COUNCIL, WEST MIDLANDS GAS BOARD, and DENT, F. J. April 22, 1954 [Feb. 9, 1953], No. 3632/53. Class 55 (2). Fuel gas consisting predominantly of hydrogen and carbon monoxide and enriched with gaseous hydrocarbons is obtained by thermally decomposing methanol and enriching the resulting mixture of hydrogen and carbon monoxide with gaseous hydrocarbons produced by the thermal decomposition of condensable hydrocarbons in the presence of hydrogen. The methanol and possibly also the condensable hydrocarbons is or are obtained by catalytic synthesis from a gas containing hydrogen and carbon monoxide for example water gas. The thermal decomposition of both the methanol and the condensable hydrocarbons is conducted at a temperature above 700‹ C. and in the presence of a suitable catalyst, suitable catalysts for the methanol decomposition are metals of the iron group in the reduced state, metal oxides such as a mixture of chromium and copper oxides or chromium and nickel oxides, and activated alumina, while for the condensable hydrocarbons metal oxides such as a mixture of chromium and copper oxides or activated alumina may be used. The process is preferably carried out in two intermittently heated zones 1 and 2, each containing a bed of a catalyst suitable for both the thermal decomposition of the methanol and of the condensable hydrocarbons. The zones 1 and 2 are connected by a conduit 3 and have outlets 4a and 4b for the enriched gas. The catalyst beds are first heated to a temperature of 1000-1100‹ C. by burning a mixture of combustible gas and air in the zones which is admitted at 5 and 6, waste gases leave at 7. When the beds of catalyst are sufficiently heated the supply of the mixture of combustible gas and air is shut off and methanol in liquid or vapour form is passed into zone 1 through 8a. The mixture of hydrogen and carbon monoxide obtained passes into zone 2. Condensable hydrocarbons are introduced into zone 2 through 9a and enriched gas is withdrawn through outlet 4a. To equalize the extent to which the beds of catalyst are cooled during a run period, the direction of flow of the gases is reversed during each run period. Thus, after a suitable interval, methanol is introduced into zone 2 through 8b, condensable hydrocarbons are introduced into zone 1 through 9b and enriched gas is withdrawn through outlet 4b. When the temperature of the catalyst beds becomes too low the flow of methanol and condensable hydrocarbons is interrupted and the beds are reheated.

Title: Improvements in radio direction-finding systems
IPC: G01S1/02
Filed: 1942-03-20
Abstract: 566,026. Wireless direction-finding systems. JEFFERSON, H. March 20, 1942, No. 3756. [Class 40 (v)] A wireless direction-finding system of the kind in which an aerial A of variable directivity feeds a receiver R, the output of which modulates the intensity of the beam in a cathode-ray tube, is provided with two timebase circuits TB1, TB2 associated respectively with the X and Y deflecting members of the tube, and means for varying the tuning of the input circuit over a wide range in synchronism with the operation of one time-base circuit and for varying the directivity of the aerial system in synchronism with the operation of the other. The time-base circuits produce line-scanning of the beam, which is increased in brightness as the frequency to which the receiver is tuned passes through that of an incoming signal, so that a trace such as that shown in Fig. 3 is produced, in which S<1>, S" represent two transmitting stations operating at different frequencies. The bearings of these stations are indicated by the points b<1>, b<11>, at which the cathode-ray is extinguished as the aerial reception pattern passes through a null position. The input circuit may include a wide-band radio-frequency amplifier, a frequency changer, and a local oscillator, the frequency of which is variable over a corresponding band, for example, by a reactance valve driven from the time-base circuit or by a variable reactance driven by a motor which synchronously controls the time-base circuit. The aerial system may comprise a rotating loop, as shown, an Adcock system with a goniometer, or a spaced aerial system with phasing means, as described in Specification 237,906, [Class 40 (v)]. The timebase circuit may comprise a multivibrator variable frequency system, a reactance valve variable frequency circuit, or a motor-driven variable condenser or inductance.
