Title: Process for the recovery of sulphuric acid
IPC: C01B17/92
Filed: 1930-10-02
Abstract: Sulphuric acid is recovered from the waste acid liquors from the refining of oils, fats and the like by concentrating the liquors until they contain, at least 60 per cent, say 60-80 per cent of sulphuric acid and then diluting them, whereupon organic impurities are precipitated and removed.  The waste acid liquors may be treated by diluting with water in the usual way to remove the major portion of the resinous and oleaginous impurities before being subjected to the above treatment.  The concentration may take place at temperatures above 100 DEG  C. of say between 150 DEG  and 190 DEG C.  Examples are given.

Filed: 1974-07-03
Abstract: 1472202 Data transmission COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 3 July 1974 [13 July 1973] 29544/74 Heading H4P A circuit for translating input binary data into a form suitable for controlling differential phase shift modulation receives m parallel input trains (where m is an integer #1) and provides an output dependent on the difference between successive adjacent words (or bits when m=1) which output is applied to the d.p.s.k. modulator. Each of p (where p is an integer #2) different series of words, where each series comprises 1 out of every p words, of the input trains is accumulated separately and the running totals of each of the p series is added modulo 2<SP>m</SP> continuously. In one embodiment, Fig. 1, m=3, i.e. 3 binary input and output trains, and p=1 giving two accumulators, 8 to which even bits are fed and 9 to which odd bits are fed. The accumulators effect a modulo 2<SP>m</SP> accumulation of words reaching them i.e. each new word is added to the previous content. Words leaving the accumulators are mod 2 added in 15 having outputs U<SP>1</SP>, D<SP>1</SP>, or Q<SP>1</SP>. Operation of components 8, 9, 15 is described with reference to a Table I (not shown) in the description. In an alternative arrangement, a single accumulator (16) which may be identical to one of those used in Fig. 1, receives directly the three streams at the original bit rate of 1/T. Outputs of the accumulator are fed directly to mod 2 adder (17), identical to 15 in Fig. 1, and indirectly through delay lines (18-20) having a delay of T which allows for the fact that (16) accumulates alternately even and odd words is series. If operational circuits are not synchronized delay lines should be adjustable. Other arrangements are envisaged by the Specification.
Patent GB-666575-A (GB)
Title: Improvements in pulse generating circuits
IPC: H02M9/06
Filed: 1948-11-15
Abstract: 666,575. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., & MELVILLE, W.S. Nov. 15, 1949 [Nov. 15, 1948], No. 29614/48. Class 38 (ii). An electrical circuit comprises a saturable cored inductance P connected in series with a substantially resistive load R, the combination being connected across a capacitor C or a capacitance network which is adapted to be charged through an inductance L from an alternating supply, the circuit constants being of such values that saturation of the core causes the charged capacitor or charging circuit to discharge through the load and produce a pulse of energy therein, the charging circuit being resonant at the frequency of the supply. When the voltage across the capacitor reaches a peak value the inductance P becomes suddenly saturated and a pulse is supplied to the load. Thereafter the inductance P becomes unsaturated and the capacitor is re-charged to produce a pulse in the opposite direction. The circuit may be used with a phase-shifting device and a pulse transformer arranged to control the output of a full-wave rectifier system comprising discharge valves, Fig. 3 (not shown). Rectifiers may be included in series with the grids of the discharge valves. When the discharge valves are required to maintain the output voltage constant despite fluctuations in supply and load, the necessary control may be obtained by varying the amplitude of the supply voltage to the saturable reactor circuit. The system may be used to generate pulses of double exponential form, Figs. 5a, 5b (not shown). A condenser/resistance element is then added to the circuit to delay both the rise and fall of the current-pulse. When it is desired that each pulse is of the same polarity, a second winding is added to the inductance P and is supplied with direct current to provide a biasing flux in the core, Fig. 4a (not shown). The capacitor C may be charged through a step-up transformer N (Fig. 7a), biasing flux in the core of the inductance P being derived from condenser M which is charged from a direct current source, provided with a de-coupling inductance S. Other methods of biasing this circuit are shown. The capacitor C may be connected in a T- network between inductance P and another saturable inductance, the unsaturated inductance of which is substantially larger and the saturated inductance substantially smaller than the unsaturated value of P, Fig. 6 (not shown). A higher rate of rise of current in the load is thus obtained. This arrangement may be used for firing two ignitrons in turn. The saturable inductance cores may be constructed of material having a substantially rectangular hysterisis loop, such as 50-50 cold rolled nickel iron. Specification 666,574 is referred to.

Abstract: 1,044,640. Electrophotographic materials. RANK XEROX Ltd. July 31, 1963 [Aug. 1, 1962 (2)], No. 30346/63. Heading H1K. An electrophotographic plate comprises a transparent electrically conductive support bearing an optically transparent layer of a resin, made by reacting an unsaturated silane with an aminoalkyl silane, upon which is a selenium layer applied at a substrate temperature of from 57‹ C. to 67‹ C. Exposure of the plate is to take place through the support. A suitable support material is glass made conductive by a surface layer of tin oxide, copper iodide, or metal. In the specific example a tin oxide coated glass plate is dipped in a solution of a resin formed by reacting vinyl triethoxy silane with γ-aminopropyl triethoxy silane. After the resin film has dried the plate is held within the specified temperature range and selenium evaporated on. The red sensitivity and the dark resistance vary with the precise substrate temperature. The temperature range is thought to be related to the formation of some degree of selenium crystallinity at the interface between the silicone resin and the selenium. It is also thought that the variation in behaviour of the materials with changing polarity depends on the formation of an electric dipole layer at this interface. The exposure characteristics of Figs. 1 to 4 (not shown) compare the materials of the invention with similar plates lacking the silicone layer.
