Title: Process for the preparation of hydrogen and of mixtures of hydrogen and nitrogen
IPC: C07C5/08
Filed: 1966-01-04
Abstract: H2 is obtained from a gas mixture containing H2, CO, and hydrocarbons, including acetylenes, by catalytic hydrogenation followed by steam conversion of CO to CO2 and removal of the CO2, and separation of H2 from the hydrocarbon and any residual CO.  The gas mixture may contain at least 60% H2 + CO, and at most 30% hydrocarbons and may be the residual gas from the synthesis of C2H2 from hydrocarbons, e.g. CH4.  Hydrogenation is effected at 100-300 DEG  C. over a Pd on Al2O3 catalyst; acetylenic and conjugated hydrocarbons are then absent.  CO conversion is effected by saturating the gas with H2O at 150 DEG  C. and passing it over an Fe and Cr oxide catalyst at 410 DEG  C., then over a Zn and Cu oxide catalyst at 200 DEG  C.  CO2 is washed out e.g. with H2O, monoethanolamine or K2CO3, and the H2 is separated by low temperature fractionation and washing with liquid N2.  The whole process may be operated under the same pressure, e.g. 8-80 atm. N2 may be finally added to give an NH3 synthesis gas.

In the lower flange 82 of the carburetter is bolted a two-part casing 83, 84 having an internal baffle formed by circular walls 102, 103 and a free-running propeller having blades 123, each of which has a flanged trailing edge 72 as shown in Fig. 9. As the propeller rotates liquid droplets in the air-fuel mixture are trapped by the flanges and thrown by centrifugal force through the annular gap between the wall portions 102 and 103, into chamber 106 which contains a reticular packing 128 e.g. metal wool, natural or synthetic fibres or a porous ceramic. The droplets drain into a well 132 and overflow through tube 131 to a closed tank 139, containing a ball-valve 146 which operates a switch 144 controlling an electric pump 142 which returns the fuel to a main supply tank 148. Continuous enrichment of air-fuel mixture. A small pool of fuel always remains in the bottom of the well and this flows to an outlet 152 at a rate controlled by an adjustable valve 174, formed by one end of a pin 156, the other end of the pin is threaded and passes through a nut 168. A slotted head 173 provides for adjustment of the position of the pin. Mixture enrichment for acceleration. Nut 168 is grooved externally and engaged by the bifurcated end of a pivotally mounted link 159, connected to the armature of a solenoid 163 which is electrically connected to a power supply through a switch 178 positioned under the driver's throttle pedal 181. When a large throttle opening is used the solenoid is energized and attracts the armature against the force of a spring 166, thus retracting valve 174 and allowing increased fuel flow to nozzle 152.

Filed: 1960-01-06
Abstract: 887,781. Radio-active measurement of thickness and density. VAKUTRONIK VEB. Jan. 6, 1960, No. 454/60. Class 40(3). Compensation for thermal variations in absorption of # radiation by the air is provided by a voltage produced by temperature sensing means. Thickness or density of sample 3 is measured by absorption of /3 rays from source 2. Ionisation current from chamber 1 develops a voltage across resistor 4 which equals a reference voltage set on potentiometer 5 at a desired thickness and density to give a zero output. At the calibration temperature bridge 6, 7, 8, 9 is balanced, but changes in temperature affect thermistor 6 to produce a compensation voltage in series with resistor 4. In modifications the potentiometer 5 may provide the bridge voltage and extra resistors may be included to compensate for position effects or the bridge may be replaced by a thermocouple and amplifier. The circuit output may adjust the potentiometer to follow the measured value.

An electric resistance heater 11 surrounds the lower part of the tube 2 which contains a volatile liquid surrounding the bellows. Another contact strip 13 crosses the strip 8 at right-angles, and is adapted to be displaced by the pin 15 on the strip 8, to break its contact at a predetermined vapour pressure. A variable resistance is connected in series with the resistance 11 to control the heating. By adjustment of the heating, and of the screw 12, the strip 8 may be caused to leave either of its contacts 9 at a predetermined temperature of the surroundings of the vessel 1, and the heating element 11 is switched off above that temperature. The contacts 9 are in the circuit of a relay for indicating or controlling temperature. A current of air across the vessel 1, without change of temperature, would operate the relay to supply heat.
