Abstract: 1,227,984. Control of exothermic chemical reactions. CHEMOPROJEKT, and CHEMICKE ZAVODY CESKOSLOVENSKO-SOVETSKEHO PRATELSTVI NARODNI PODNIK. 6 May, 1968 [4 May, 1967], No. 21314/ 68. Heading B1X. [Also in Division Cl] An exothermic chemical reaction is carried out by passing a preheated fluid reactant stream 28 to the nozzle (or nozzles) of injector system 5 which draws in part of the product stream 6 from the reaction zone 7, passing the composite stream of reactant and recycled product through line 10 into reaction zone 7, and injecting cool reactant from line 8 into the nozzle (or nozzles) of system 5, or into recycle line 6, or into line 10. As shown, the non-recycled product from zone 7 is cooled in heat-exchanger 4 and then passed to the injector system 11 of a second reaction, zone 12, which is also operated with partial product recycle and with temperature control by means of cool reactant. As applied to the synthesis of ammonia, the reactant stream comprises a compressed mixture of H 2  and N 2 , and zones 7 and 12 each contain a layer of catalyst. There is also a third catalytic reaction zone 18, but this is not operated with productrecycle. The effluent from zone 18 (i.e. ammonia product) is cooled in heat-exchangers 19 and 2, and withdrawn from the system through outlet 24. The initial feed mixture 1 is preheated by passing it through heat-exchanger 2, the heat-exchange tubes 3 of reaction zone 18, heat-exchanger 4, and electrical preheater 25; the preheated feed then flows to injector system 5. Cooling water is passed into the coils of heat-exchangers 17 and 19; and hot water and/or steam is discharged therefrom.

Abstract: 1,239,184. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 22 Jan., 1970 [3 Feb., 1969], No. 3245/70. Heading G4C. Apparatus for decoding a data signal which represents a train of coded digital data as a succession of timed transitions of the data signal, decodes each transition in dependence upon the length of the time interval between the transition and the previous transition, which it measures, and upon the result of decoding the previous transition. Data from a magnetic disc, drum, tape or strip in " modified frequency encoding " form (i.e. a transition at the centre of the bit cell for 1, and at the beginning of the cell for 0, except that if a 0 follows a 1, no transition is provided for the 0) is fed to a peak pulser which provides a pulse for each transition. Each pulse resets and reads out (to a time register) a clock-driven counter which thus measures the time intervals between successive transitions. Each count thus read out is multiplied in an arithmetic logic unit by a correction factor (see below), reinserted in the time register, and then supplied to a sequential logic circuit which can be in one of a number of states. The sequential logic circuit responds to the range (one of ten) in which the corrected time interval lies and the current state of the circuit to place one or two bits in a data register (which assembles an 8-bit byte) and choose the next state of the circuit. A bit time counter counts the number of bits thus recognized, and on a count of 40, causes the arithmetic logic unit to divide 40 by the contents of a total time register which has been accumulating the successive corrected time intervals, the result of the division updating the correction factor mentioned above, which thus compensates for long-term variations in storage medium speed. Shortterm variations are compensated by obtaining an average value for the time intervals over a plurality of bit cells, comparing it with a nominal value, and decreasing or increasing each time interval count by an appropriate correction. An error indication can be given if the combination of the range in which the corrected interval fed to the sequential logic circuit lies, and the current state of the latter circuit, is one which should not occur. A modified embodiment measures the time intervals by using each transition pulse to reset a ramp generator, the (rising) ramp being applied through a chain of resistors to a plurality of comparators for comparison with reference voltages, the outputs of the comparators (indicating ramp greater than reference, or not) being converted to 1-out-of-10 form by logic to indicate the time interval at the next transition pulse. The invention is also applicable to data using double frequency encoding, NRZ, NRZI, phase modulation or ternary coding. The data is in any case preceded by a burst of zeroes or ones for synchronization.

Abstract: 1,258,309. Semi-conductor devices. GENERAL ELECTRIC CO. 27 March, 1969 [9 April, 1968], No. 16207/69. Heading H1K. In a semi-conductor device comprising a wafer enclosed in a sealed housing and contacted by electrodes on opposite faces mounted under pressure by means of an external thrust member acting on one of the electrodes, a strain buffer of a material having a coefficient of expansion approximately the same as that of the semi-conductor material is disposed between the thrust member and the electrode. The strain buffer prevents distortion of the wafer due to friction at the sliding pressure contacts during thermal cycling. As shown, a thyristor 12 comprising a silicon wafer (22) mounted on a tungsten or molybdenum plate (23) is disposed between two ductile dish shaped electrodes 29, 30 of copper, silver, aluminium or brass, plated with nickel, silver or gold brazed to the ends of two ceramic cylinders 34, 35. The upper face of the semi-conductor wafer is provided with a coating (25) of gold, silver, indium, rhodium or nickel, and the lower face of the carrier plate is coated with a layer (24) of gold-nickel alloy. The gate electrode (26) of the thyristor is connected to an annular plate 37 brazed to the upper end of cylinder 34 and the edge of the wafer is covered with a layer 28 of silicone rubber. The lower end of the ceramic cylinder 35 is also provided with an annular plate 36 which is welded to plate 37 in an inert atmosphere to complete the housing. The dish shaped electrodes 29, 30 are pressed into contact with the thyristor structure by means of posts 20, 21 of copper, aluminium or brass the ends of which are coated with silver, nickel or gold. A strain buffer 45 of tungsten, molybdenum or chromium or an iron-nickel or iron-nickelcobalt alloy plated with nickel, silver or gold is disposed between the upper post 21 and the upper electrode 30. The surfaces of the buffer may be lubricated with a thin film of silicone oil to reduce the friction at the sliding contact. The upper electrode 30 is shaped to clear the gate contact and its connection to the ring 37 and the post 21 and strain buffer 45 are correspondingly shaped. The strain buffer 45 may be brazed or otherwise attached to the lower end of the post 21. Resilient rings 46 are provided to support the housing between the posts. The semiconductor device may comprise a rectifying diode instead of a thyristor.

An exchange sets up connections over transmission relay sets which are of different sorts according to the manner of transmission required and which are selected in accordance with a code sent by the calling subscriber before he indicates the identity of the wanted subscriber. The kinds of transmission catered for are speech, teleprinter, data, and video transmission. For speech connections, or for any subscriber calling or called that has only one kind of transmission facility and no choice of transmission relay set, the appropriate relay set may be connected up by the exchange common control on the basis of class-of-service data and without need of a dialled prefix. Switching between speech and data equipment at a substation can be effected manually or can be effected automatically by the common control. Some transmission relay sets may provide for conversion of signals such as converting visual display signals to teleprinter codes. Subscribers may dial for access to a data processing facility or a microfilm library.
