Title: Improvements in or relating to the control of industrial installations
Inventor: ROUXEL ROLAND
IPC: G05B13/02
Filed: 1963-02-25
Abstract: 1,025,144. Automatic control systems. R. ROUXEL. Feb. 25,1963 [Feb. 26, 1962], No. 7540/63. Heading G3R. Industrial plant is automatically controlled to run under optimum conditions by sequentially controlling input variables to bring the time derivative of a measured quantity to a maximum. A furnace 40 has a predetermined fuel supply at 41 and primary and secondary air in duct 43, 45 controlled by electromagnetic valves 44, 46. The temperature as measured by a pyrometer 47 and the output signal differentiated at 49 is fed to a switching circuit in block 52. When the input signal to block 52 decreases flip-flop 56 changes state to operate switch block 71 changing the polarity of the correction signal from source block 78 which is applied, as shown, through selector switch block 70 to integrator and corrector block 89 controlling valve 44. This selector switch changes only when the input to its flip-flop goes from negative to positive (i.e. every second operation of switch 52, to change the connection of the correction signal from block 89 to block 90 (controlling valve 46) and V.V. Modifications (i) switch 85 in block 70 enables the selector switch to be operated from an outside source e.g. a time-switch (ii) switch 98, 99 enables the automatic control to be disconnected, and manual control effected by potentiometers 101, 103. (iii) alternatively the maximum (optimum) operating condition may be determined by detecting when the second derivative changes sign. A modified switching circuit 52 for this purpose is illustrated in Fig. 4 (not shown). (iv) The correcting signals instead of being constant may vary between two limits according to the value of the second derivative, as illustrated in Fig. 5 (not shown). A circuit for this purpose is illustrated in Fig. 6 (not shown).

Title: Improvements in or relating to the manufacture of ferro-manganese
IPC: C22C35/00
Filed: 1945-03-26
Abstract: A process for the manufacture of ferro-manganese which consists in reacting together by the aluminothermic method manganese ore having a basis of MnO2, finely divided carbon and aluminium or aluminium alloy.  The powdered carbon, which may be in the form of charcoal, coke or coal low in volatile content and which may be used in proportion of 2-6 per cent. based on the weight of ore, may be mixed with the finely divided manganese ore.  The aluminium or aluminium alloy may be employed in powder form or in the form of chippings, stampings, turnings or borings not exceeding 3/8 inch to 1/2 inch in size, and may be used in a proportion of 25-32 per cent. based on the weight of ore.  The fluxes usually employed in aluminothermic processes may be mixed with the constituents of the mixture.  A specific example of the process is referred to, resulting in the production of ferromanganese containing manganese 84 per cent., iron 11 per cent., silicon 2.5 per cent., and carbon 0.16 per cent.

Abstract: A feedstock comprising a major proportion of aromatics and mono-olefines and a minor proportion of gum-forming constituents, is contacted in the presence of hydrogen with a supported nickel catalyst, for example on sepiolite, alumina, chalk, kieselguhr, or silica gel, or nickel and cobalt on an aluminium silicate base, which under operating conditions contains a major proportion of nickel in elemental form, whereby at least a sufficient proportion of the gum-forming constituents are destroyed to give a product having a Diene index not greater than 0.1, and the product, or a fraction thereof, is contacted together with hydrogen with a hydrogenation catalyst, for example cobalt oxide and molybdenum oxide on alumina, whereby a sufficient proportion of the mono-olefines is converted into paraffins to give a product having a Bromine number not greater than 5.0.  The feedstock may be a raw steam-cracked gasoline, or may be obtained by distilling such a gasoline to obtain a fraction predominating in C6-C8 hydrocarbons, in which case the gasoline may have been previously located with hydrogen in the presence of a supported nickel catalyst to destroy part of the gum-forming constituents.  The hydrogen may be passed as separate feeds to the zone, or in co-current to the feedstock.

Filed: 1970-02-24
Abstract: 1298996 Lightning arresters GENERAL ELECTRIC CO 24 Feb 1970 [3 March 1969] 8805/70 Heading H2H A lightning arrester is similar to that described in Specification 1,283,516 but the coil 13 is shunted by a spark gap formed by electrodes 15, 16. Initially the over voltage surge arcs across the spark gap but as the voltage and current decline the arc is extinguished after a predetermined time dependent on the inductance of the coil and the current is diverted through the coil. The magnetic field generated by the current in the coil drives the arcs against the arc quenching walls of the chambers. The rate of decrease of current in the coil is retarded by the back e.m.f. generated in the coil. In a modification the electrodes 15, 16 are replaced by a block of non-linear resistive material positioned between a pair of terminal plates.
