Title: Process for the dehydrogenation of aliphatic hydrocarbons
IPC: C07C5/32
Filed: 1937-03-30
Abstract: Aliphatic hydrocarbons are dehydrogenated by contacting them for periods of 0,1-7 seconds at temperatures of 450-700 DEG  C. with a granular catalyst comprising a major proportion of a refractory carrier of low catalytic activity supporting a minor proportion of a more active catalyst selected from compounds, particularly oxides, of titanium, zirconium, cerium, hafnium and thorium.  The reaction may be effected at pressures of 0,25-7 atmospheres.  The preferred carriers are oxides and silicates such as alumina, magnesia, bauxite, Montmorillonite clays, bentonite clays, kieselguhr silica, firebrick, and glauconite. The proportion of active catalyst to carrier may be less than 10 per cent.  The catalyst may be in the form of compressed particles, such as pellets, or granules of 1,6-12 mesh per cm. Paraffins may be converted into mono-olefines by contact of 0,5-7 seconds at atmospheric pressure, mono-olefines into diolefines by contact of less than one second at 0,25 atmospheres pressure, and paraffins into diolefines by contact of 0,1-2 seconds at subatmospheric pressure.  The reaction is effected in the absence of water vapour.  The furnace may be of the regenerative type with alternate heating and reaction periods, the catalyst serving also as heat-accumulating material. Specifications 409,312, 466,609, and 483,417 are referred to.ALSO:Aliphatic hydrocarbons are dehydrogenated by contacting them for periods of 0,1-7 seconds at temperatures of 450-700 DEG  C. with a granular catalyst comprising a major proportion of a refractory carrier of low catalytic activity supporting a minor proportion of a more active catalyst selected from compounds, particularly oxides, of titanium, zirconium, cerium, hafnium, and thorium.

Title: Improvements in voltage measuring systems
IPC: G01R1/28
Filed: 1963-03-08
Abstract: 968, 799. Voltage measurement. LEEDS & NORTHRUP CO. March 8, 1963 [March 13, 1962], No. 9338/63. Heading G1U. A voltage measuring system includes an adjustable potentiometer 21 for producing a balancing voltage which varies between minimum and maximum values as the potentiometer is adjusted between its limits, an adjustable current shunt 26 for adjusting the range between the minimum and maximum values, input circuit leads 25, 32 to which the voltage to be measured is applied, a detector 11 connected to the potentiometer and to the input circuit, a motor 12 responsive to the output of the detector 11 for adjusting the potentiometer so as to reduce unbalance, a stable source of supply 27 for developing an adjustable calibrating voltage and a switch 33. This switch is used for connecting the calibrating voltage into the input circuit either in place of the voltage to be measured to enable the range to be adjusted by use of the adjustable shunt 26 to a required value set up by the stable source 27, or in series with the voltage to be measured so as to establish the lower limit of the measuring range in accordance with an adjustment of the stable source. The arrangement is particularly adapted for example for measuring the output of a thermocouple 24 which may vary between say 1, 200‹F. and 1, 300‹F. The potentiometer and adjustable shunt 26 are arranged to give a full scale deflection over 100‹F by comparison with an appropriate output from the adjustable supply 27, and then the switches are altered so as to bring this supply into circuit after readjustment thereof to establish the lower limit of the measuring range at 1200‹F. The adjustable shunt arrangement 26 consists of two Ayrton type adjusting shunts, one fine and one coarse, connected in back to back arrangement. The coarse shunt consists of a plurality of series resistors 59 connected into two sections, each having one end connected to a different side of the potentiometer 21, and a switch 57 arranged so that it concurrently removes a resistor of one section from the circuit and inserts a resistor from the other, while the shunt for fine adjustment consists of a slide wire 63 connected between one end of the potentiometer and the opposite end of the one section of series resistors having one end connected to the opposite side of the potentiometer. The movable contact 63a of the slide wire is connected to a source of supply 60 whose other terminal is connected to the one end of the potentiometer. Details of the setting up of the equipment are given in the Specification.
