Title: Process for the cracking of liquid hydrocarbons
IPC: C01B3/38
Filed: 1964-03-16
Abstract: In a single-stage process for the continuous catalytic cracking of liquid hydrocarbons with steam at 400 DEG  to 600 DEG  C., the temperature and the retention time of the feed in the reactor are controlled to give a gas product of desired calorific value, e.g. for use as town gas.  The catalyst, which may be in a fluidized bed, is nickel, cobalt, or cobalt-molybdenum, and oxygen, oxygen-enriched gases or air may be delivered to the reactor.  The pressure may be up to 50 atmospheres gauge, and to obtain complete cracking with low retention times, e.g. less than 1 second, the grain size of the catalyst should be from 0.1 to 2 mm., preferably 0.2 to 0.5 mm.  Some cracked gas may be recycled, e.g. after being cooled and separated from condensate, and may be mixed with vaporized feed hydrocarbons for passage at 200 DEG  to 500 DEG  C. over a desulphurizing catalyst. The feed is preferably light gasoline (boiling range 35 DEG to 125 DEG  C.), although hydrocarbons with boiling points up to 250 DEG  C. may be used. Five specific examples are described.

Title: Improvements in or relating to radar systems
IPC: G01S13/42
Filed: 1945-05-02
Abstract: 599,554. Radiolocation ; thermionic distributers. WEBLEY, R. S., and ROBSON, J. M. May 2, 1945, No. 11197. [Class 40 (v)] In a pulse radar system of the kind described in Specification 598,649, wherein the main reception lobe of the directional receiver performs a continuous conical scan and traverses four predetermined positions in its orbit coincidently with the transmission of exploring pulses, means are provided for deriving in separate channels substantially continuous D.C. voltages dependent on the intensities of the signals received at the successive lobe positions, the means comprising for each channel a condenser which is charged through a thermionic valve and discharged through a high resistance, each valve being rendered conductive in turn as the lobe passes through successive ones of the four predetermined positions. The echo signals are applied to the control grid of the valve V1, to the suppressor grid of which is applied a strobe pulse for selecting signals from objects at a particular range. The voltage at the anode of VI varies, during the strobe pulse interval, in accordance with the signal amplitude, so that when a suitable signal is received the cathode of diode V3 falls until the bias applied to it is overcome, whereupon it conducts and C3 is charged to an extent depending on the signal received under the strobe. When V1 is cut off again, the charge on the condenser leaks away with a time constant of 400 microseconds. A pulse shaping circuit is placed between the cathode of V3 and the grid of valve V4 so that a lengthened symmetrical pulse of amplitude corresponding to the signal under the strobe is obtained. The output voltage from the valve V4 is applied through condensers C5, C6, C7, C8 to the anodes of double-triodes V5, V6. Two switching waves in phase quadrature are applied to the grids of V5 and V6 from input terminals 44, 45, 46 at the frequency of the conical scan, so that the four triodes of valves V5, V6 become conducting in succession when the lobe is in its predetermined positions. Each of the condensers C5, C6, C7, C8 becomes charged, in succession, as the corresponding triodes conduct, to an extent depending on the signal under the strobe at that position of the reception lobe, and then when the triodes cease conducting the charge leaks away through high resistances connected in parallel with the valve. The mean D.C. potentials at the anodes of the valves which are taken to the outputs 71, 72, 73, 74 are consequently proportional to the signals received in the four predetermined positions of the reception lobe. The output D.C. voltages are employed for the display of elevation and bearing alignment, for automatic correction of the elevation and bearing and for automatic gain control as described in Specification 599,389.

Abstract: 1453381 Preparing cellulose ether compositions BEROL KEMI AB 13 March 1974 [14 March 1973] 11275/74 Heading C3F A composition comprising a water-soluble cellulose ether and an alkali metal salt is made by forming alkali cellulose, treating this with a reagent to form the required ether and then neutralizing the residual alkali with the acid corresponding to the salt. The composition is intended to be an additive to calcium sulphate-based plasters and consequently the cellulose ether must be chosen from those which have water-retaining properties when present in the plaster and the salt must have the ability to retard the rate of setting of the plaster. The preferred salts are phosphates, citrates, gluconates, tartrates, lactates and succinates. Preferred ethers are methyl-hydroxyethyl, hydroxyethyl, ethyl hydroxyethyl, methyl hydroxypropyl, ethyl hydroxypropyl, hydroxypropyl, hydroxyethyl-hydroxypropyl and ethylhydroxyethyl-hydroxypropyl celluloses.

Abstract: 1347874 Etching AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY 27 April 1971 [28 April 1970 14 Sept 1970] 11711/71 Heading B6J [Also in Division H1] A device comprising a monocrystalline compound semi-conductor substrate is provided with an inwardly splayed-out groove wider at its base than at the substrate surface by selective use of suitable etchants on particular crystal planes and along particular crystal axes. In an example, etching GaAs with a Br 2 -CH 3 OH etchant on to a (100) plane through a mask defining an aperture aligned along the [011] direction will result in a groove of the desired cross-section. The use of (211) or (311) planes results in inwardly splayed-out grooves of asymmetrical cross-section. Other semi-conductors to which the invention may be applied include GaP, GaAs x P 1-x , ZnS and CdS, masking being effected by means of a layer of Al 2 O 3  or SiO 2  deposited by electron beam evaporation. Fig. 6 shows a monolithic assembly of Gunn diodes, each of which is situated in a bridge 8 defined by etching a pair of inwardly splayedout grooves so close together that they merge at a level spaced from the surface. The space between the bridges 8 may provide air-cooling or may be filled with a heat conducting material. Fig. 8 shows a Schottky-barrier-gate field effect transistor wherein the evaporated Schottkybarrier-gate metal 14 is situated on an N-type epitaxial layer 13 within an inwardly splayedout groove 18 etched through an N<SP>+</SP> epitaxial or diffused layer 17. The lateral edges of the gate 14 are spaced from the edges of the groove 18 due to the masking effect of the overhanging upper edges of the groove 18. Ohmic source and drain electrodes may be of the same metal as the Schottky-barrier-gate 14 or may, for GaAs, be of Sn, Pt, Au-In-Ge or Sn-Ag. In the latter alternative an upper layer of the Schottkybarrier metal may also be provided. Several integrated circuits including one or more Schottky-barrier-gate FET's are described. A PN junction gate FET may also be formed by ion bombardment of a suitable dopant into a part of the base of an inwardly splayed-out groove, masking being effected by the combination of the overhanging upper edges of the groove and a metal layer on the upper surface of the substrate.
