Title: Improvements in or relating to an electrical circuit which includes a semi-conductorcrystal
IPC: H01L27/102
Filed: 1957-01-23
Abstract: 854,908. Semi-conductor pulse circuits. SIEMENS & HALSKE A. G. Jan. 23, 1957 [Jan. 23, 1956], No. 2508/57. Class 40(3). [Also in Group XXXVI] An electrical circuit includes a semi-conductor element having a sequence of emitter electrodes lying between two base electrodes of differing potential, the junction biases of the emitters varying stepwise along the sequence, the arrangement being such that equal pulses applied to the input terminal switch on successive emitter electrodes. Fig. 2 shows a pulse counter comprising an N-type semiconductor body H having a longitudinal electric field produced by means of ohmic base electrodes B 1  and B 2 . A sequence of PN junction emitter electrodes I to X lying along the body at 5 volt intervals are each connected via a resistor 18 a potentiometer RO at one volt intervals; initially emitters 1, 2 and 3 etc. are reverse biased 1, 5 and 9 etc. volts successively. When an input of + 2 volts is applied to input terminal E, emitter I conducts and the injected carriers reduce the resistance of that portion of the body so reducing the reverse bias on emitter 2 which is then conditioned to become conducting on the next input pulse and repeat the process for emitter 3. Voltmeter V across the body thus indicates the number of input pulses. The 10th pulse may be arranged to apply a further pulse to E to restore all emitters to cut off, or to connect the input to a second counter. Capacitors C1 to C9 render the circuit substantially independent of pulse amplitude and duration. The circuit may be used to produce a predetermined number of pulses by altering the bias supplied from potentiometer RO and adding switches between each emitter and its respective resistor R1 to R10, (Fig. 4, not shown). Fig. 5 shows an alternative arrangement in which the emitters are arranged along an initially equipotential line between base electrodes B 1  and B 2 . Pulses applied to B 2  via transformer T again render, the emitters conducting sequentially owing to changes in the potential distribution in the body. A "flip flop" arrangement is described (Fig. 6, not shown) in which emitters D 1  or D 2  are cross coupled and either D 1  or D 2  is conducting; pulses applied to auxiliary electrode Z lying between the emitters, effects changeover. Fig. 8 shows a decade counter having the odd and even auxiliary electrodes Z 1  to Z 10  connected in separate groups, the input pulses being applied to each group alternately. When for example, emitter D 3  is conducting, this conditions D 4  so that when the next pulse appears at auxiliary electrode Z 4 , D 4  conducts. In a modification, two sets of auxiliary electrodes are used which enables the direction of travel of the conducting condition of the emitters to be controlled. Specification 823,987 is referred to.

Title: A process for the production of catalysts
IPC: B01J21/12
Filed: 1947-01-29
Abstract: Gel-type catalysts of large surface area are obtained by displacing water in a hydrous metallic oxide gel or hydrous silica gel with a non-aqueous liquid at least partially miscible with water and having a boiling point below 200 DEG  C., heating the gel with said liquid under a pressure of at least 100 lbs. per square inch to a temperature between the normal boiling point and the critical temperature of the liquid and then exploding the gel by sudden release of the pressure.  Cracking catalysts consisting of the oxides of silicon, aluminium, zirconium and magnesium, alone or in admixture, are thus prepared, as also are catalysts consisting of the oxides of beryllium, zinc, tin, thorium, vanadium, chromium, molybdenum, tungsten, uranium, manganese, iron, cobalt and nickel. Specified liquids are methanol, ethanol, the propanols, the butanols, the lower boiling aliphatic ketones and the lower boiling aliphatic amines, water being displaced in the gel by washing in a stream of the liquid.  The gel may be exploded batchwise or continuously, in which latter case the gel suspended in the liquid is injected under pressure into a low-pressure chamber.  The gel, after it has been exploded, may be calcined.  In an example, a silica-alumina hydrogel is washed with isopropyl alcohol to produce an alcogel, which is then heated to 197 DEG  C. in an autoclave provided with a bursting disc adjusted to explode the gel at a pressure of 375 lbs. per square inch.

Abstract: 524,326. Retort &c. furnaces. LEISTIKOW, F. W. R. (Krupp Akt.-Ges., F.). Jan. 27, 1939, No. 2845. [Classes 51 (i) and 51 (ii)] In an apparatus for heating material in bulk comprising parallel retorts or chambers separated by heating-flues 1, connected for a closed-circuit flow of heating-gases, and with the inlets and outlets 5 to and from the flues 1 at the same end of the structure, the external connecting channel or channels 7 between the inlets-and outlets is so arranged that each of the parallel heating-gas currents travels in a separate or substantially separate circuit. In the construction shown the channel 7 extends across the width of the battery of retorts and forms a casing for an impeller 8 of the Root's blower type which, although not divided would tend to preserve the individuality of the circuits. Fresh heating-gases are supplied through the connection 9, and surplus gases are exhausted at 10. The gases may be directed in the fires by baffles 11. In a modification, Fig. 4, not shown, the fresh gases supplied to the circuit are generated under pressure either by continuous or explosive combustion and are used injector fashion to maintain the circulation. When the settings are of considerable height or width two or more groups of parallel circuits may be used. Specification 458,298 is referred to.

Title: Improvements in or relating to automatic telephone systems
IPC: H04Q3/00
Filed: 1942-03-06
Abstract: 549,325. Automatic exchange systems. WESTERN ELECTRIC CO., Inc. March 6, 1942, No. 2925. Convention date, Feb. 8, 1941. [Class 40 (iv)] In a non-numerical switching arrangement traffic is spread with the aid of discharge tubes each of which controls access to a particular group of lines and has its sensitivity adjusted in accordance with the extent of occupancy of the group. In the cross-bar system shown, access to the group of lines 106 reached over a group of secondary switches is controlled in each primary switch by a tube such as 109 having its priming cathode connected directly to the test wire of the link with which it is associated and over an individual resistance 124 and a common resistance 129 to the negative pole of a source 130. As the links become busy, the potential drop across 129 increases and the potential difference between the priming electrodes is reduced. In consequence, when a call is initiated and circuits are completed for all the tubes of a primary group, the tube associated with a heavily occupied secondary group is less likely to strike than one associated with one less occupied. Circuit details.-When subscriber 201 calls, line relay 202 completes a priming circuit for an individual discharge tube 210 over hold magnet 203 and relay 213 which remain unoperated. If no other line is calling and the screen grid 217 therefore is at ground potential, the main gap 211, 220 at once breaks down and relay 213 operates (but not magnet 203) and connects positive battery to the priming anodes of all the link circuit tubes. The priming cathodes of these tubes are, as previously described, connected to ground if the corresponding link is busy or to negative potential if it is idle, the potential varying however in accordance with the extent of occupancy of the secondary switch to which the link leads. The tube to reach the breakdown stage first is therefore one belonging to an idle link leading to a comparatively unoccupied secondary switch. The initial flow of current from the priming anode to the main cathode sets up a voltage to prevent the breakdown of other tubes. Shortly afterwards the main discharge takes place through the select magnet (e.g. 241) which shunts resistance 214 to enable the hold magnet such as 203 of the calling line to operate in the discharge circuit of its tube 210. After a further interval, 215 pulls up, puts out all the tubes, releasing 213, 241, and then falls back again.
