IPC: C10G15/00
Filed: 1939-08-18
Abstract: 533,715. Heating coal by electricity; cracking oils. BLAKEMORE, B. Aug. 18. 1939, No. 23802. [Class 39 (iii)] [Also in Group III] Light hydrocarbons such as benzene are obtained from bituminous coal by heating the coal with an electrically conductive reducing agent in a closed furnace under reducing pressure by high frequency induction to between 650‹ and 800‹C. the volatiles being reacted with the heated reducing agent, and heavier distillates being subsequently cracked. The coal, the coke reducing agent and primers such as lumps of coke or mild steel scrap are charged into the furnace chamber 11 which is surrounded by a high frequency induction coil 12. The distillates pass through a grid 13 to a condenser 15 from which lighter hydrocarbons pass by a pipe 16 and fan 17 to an absorption tower 18 sprayed with oil from a sprinkler 19, the oil flowing out through a pipe 20 to a fractional separation plant. The heavier hydrocarbons are pumped up to a tank 22, and pass under pressure to nozzles 27 in a furnace 26 which are directed on to a heap of coke 29 heated by induction from a coil 31. The cracked vapours pass through a grid 28 and pipe 30 to a condenser 32 and absorption tower 33. The heavy hydrocarbons from the condenser 15 may be injected into the furnace 11. Cracking plant other than that described may be employed.

Title: Improvements in screening apparatus
IPC: B07B1/34
Filed: 1927-09-12
Abstract: 292,392. Leahy, R. A. Sept. 12, 1927. Fixed sieves.-The screening medium A is moved intermittently in one direction by the action of a pulsating column D of liquid and means are provided to impart to the medium a quick return movement and sudden stop. In the construction shown, the screening medium is adjustably tensioned between a fixed and a movable support 4, 5 and is connected to a bar B by means of a rigid transverse member J. Pulsations are imparted to the liquid column bv a rotating cam F and piston G and transmitted to the end of the bar B which works in a cylinder C. The return movement is caused by a spring E and the sudden arrest of this movement by a collar 1 on the bar B engaging an abutment 2 on a fixed cross-bar 3. Alternatively, the return movement may be obtained by a second liquid transmission device or by the natural resiliency of the tensioned screening member, and the piston and cylinder arrangement may be replaced by flexible diaphragms. The invention is shown applied to the actuation of a battery of screens from a single source of power.

Title: Method of producing elements from their halides
IPC: C22B5/12
Filed: 1959-07-14
Abstract: Boron, silicon and those metals of which the <PICT:0928853/III/1> halides are capable of forming addition compounds with ammonia, particularly the light metals, the transition metals, germanium and tin, are extracted from their halides in a two stage process. In the first stage an intermediate addition product is formed of the halide with ammonia or at least two of the gases nitrogen, hydrogen and ammonia, the product persisting at least for a short time, and in the second stage the metal is obtained from this intermediate product. In a particular process described, liquid halide 11 from nozzle 12 (Fig. 1) reacts in vessel 13 with gaseous reagent from nozzles 15, forming a solid intermediate product which is transferred by screw conveyer 21 to conveyer 24 which carries it through chamber 25.  In this zone the intermediate product is acted upon by streams of hydrogen and/or nitrogen which have been ionized by passage through electrodes 35, to yield a free metal product 26.  In a modification shown in Fig. 2, the two stages of the reaction take place within the same chamber.  By insulating nozzle 12 from the container and applying a suitable voltage, the first stage of the process may be carried out under partial ionization.  As an alternative second stage of the process, the intermediate product may be calcined in ammonia to yield a substance which may be dissolved in a fused salt electrolyte and the metal recovered by electrolysis, or which may be treated with nitric acid before such electrolysis. Specifications 804,916 and 901,022 are referred to.

Title: Signal amplifier

IPC: G01S5/30
Filed: 1966-05-31
Abstract: 1,089,085. Interference suppression; wave energy position finding. BENDIX CORPORATION. May 31, 1966, No. 24239/66. Headings H4D and H4L. The invention generally relates to the reception of randomly occurring pulses of distinctive frequency in a high noise environment. It particularly describes a position finding system for a ship, wherein, a plurality (e.g. four) transponders are placed in known positions on the sea bed, and reply with pulses of distinctive frequencies to an interrogation pulse from the ship. By timing the replies the distance of the ship to each transponder is determined thereby enabling the determination of the ship's position. The acoustic reply pulses are received at the ship's transducer 10 against a high background of widely spectrumwise distributed noise. After transformation into electrical signals and amplification, the noise and replies are passed through a broadband bandpass filter 14, having a bandpass just sufficient to pass all the replies. The passed noise and the replies are fed to a very highgain saturable amplifier 16, which since it saturates to a constant limit with only low noise at its input, may be considered, as a limiter. The output of " limiter " 16 is constant in amplitude and comprises an always present noise component, made up of frequency components having individual average low amplitudes, and the reply pulses of constant frequency and constant high amplitude. The reply pulses are separated out by respective narrow band filters 20-26, and via detectors and smoothing filters (not essential) cause Schmidt trigger circuits 50-56 to trigger, thus giving the required timing of the replies, the noise frequency components falling within the bands of the filters 20-26 being at too low an amplitude to trigger the circuits 50-56
