Title: Improvements in or relating to systems for monitoring electrical signals
Inventor: TERRY MICHAEL TREACHER
IPC: H04S7/00
Filed: 1956-04-26
Abstract: 814,318. Monitoringtwo or more sets of signals. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 11, 1957 [April 26, 1956], No. 12839/56. Class 40 (4). In an arrangement for monitoring two or more sets of signals, the signals are so fed to the monitor that it functions in accordance with the negative and positive peak values of all the sets of signals. As shown, there are two sets of signals, which may be those of a binaural transmission system, and these sets of signals are fed to amplifiers 1 and 6, respectively, the secondary windings of the output transformers 2, 7 being connected to the full-wave rectifying valves 3, 8. The rectified outputs are connected in parallel to a reservoir capacitor 4 shunted by a load resistor 5. The transformers 2, 7 and valves 3, 8 provide an effective resistance through which capacitor 4 is charged, the time constant of the circuit being small so that at any time the voltage across the capacitor 4 approximates, to the negative or positive peak value of the two sets of signals. This voltage is fed to a monitor consisting of a current measuring meter 10 by a coupling circuit 9, having a high input impedance, which provides an output current sufficient to drive the meter. The time constant of capacitor 4 and resistor 5 is sufficiently long to maintain the voltage across the capacitor 4 for a time sufficient to enable the meter to indicate a peak signal of short duration. The output current from the coupling circuit may be any desired function of the input voltage. The coupling circuit may be used to generate AGC voltages for controlling the gain of individual amplifiers from which the sets of signals are respectively derived.

Title: Improvements in or relating to the recovery of by-products obtained from sulphuric acid refining processes of petroleum products
IPC: C10G17/06
Filed: 1953-05-12
Abstract: Monocyclic and/or polycyclic polymethylene sulphides are separated from non-sulphurized products and organic disulphides and/or polysulphides which contaminate them in the spent acids from the sulphuric acid refining of petroleum products, by a process which comprises either treating said acids with a diluent consisting of a mixture of water and unreactive hydrocarbons which are unaffected by and only slightly soluble in cold concentrated sulphuric acid, or diluting the crude sulphurized oils obtained from spent acids with said unreactive hydrocarbons, the sulphurized oil solution obtained in either case being extracted by cold concentrated sulphuric acid in a proportion not greater than 10 Kg sulphuric acid per 1 Kg sulphur contained in the solution in the form of polymethylene sulphides, separating the acid layer then formed, and diluting said acid layer in water to obtain said polymethylene sulphides in an upper layer, the sulphuric acid extraction and the dilution of the acid layer in water being carried out at or preferably below room temperature, for example in the range 0 DEG  to 10 DEG  C.  Several successive purifications may be carried out as above and the process may be operated continuously.  The hydrocarbon should have a low viscosity and a boiling point outside the boiling range of the polymethylene sulphides to be obtained.  Straight or branched chain aliphatic hydrocarbons or polycyclic saturated hydrocarbons, alkylated or non-alkylated, or a mixture thereof, may be used.  A hydrocarbon gaseous at room temperature, e.g. propane or butane, may be used, the vaporization of which automatically regulates the temperature. According to Examples (1) and (3) single stage treatments of spent acid use n-heptane and cyclohexane respectively as the unreactive hydrocarbons; (2) describes a two-stage purification using iso-octane in the first stage and n-heptane in the second; (4) describes a continuous two-stage purification starting from spent acid from paraffin oil refining wherein the treatments with hydrocarbon, acid and water are carried out in a series of mixers and separators, the hydrocarbon phase (a light petrol) being regenerated by distillation after the first stage of purification and being recycled from the second stage back to the first mixer, and the final product is washed with dilute caustic soda.

Title: A system of transmission to a distance of magnitudes which can be represented by angular values
Inventor: DUREAU GABRIEL HENRI LEON
IPC: G08C19/14
Filed: 1956-05-01
Abstract: 828,918. Electric selective signalling systems. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. May 1, 1956 [May 25, 1955; April 12, 1956], No.13409/56. Class 40 (1). In a system for the distance code transmission of magnitudes which are represented by angular values code signals based on corresponding ordinates of a pair of symmetrical sawtooth voltage curves displaced by r/2 with respect to one another are transmitted, the ordinates being measured from one of two abscissa lines forming the envelope of said curves, vertically towards the other of said lines. A cyclic binary type code, Fig. 2, which is transmitted by the absence or presence of a number of frequencies conveys two voltage values which are indicative of the angular value to be transmitted on the basis of voltage curves F and G, Fig. 1. The curves which increase and decrease linearly are displaced from each other by #/2 and the two voltages are coded in columns N3-N0 and columns N5, N4, N1, N0, respectively. The voltages reconstituted in the receiver are applied mutually at right-angles to diametrically opposite points on a circular tapped resistance and a moving contact indicating the angular value is driven by a follow-up system to the resulting null point. Eight oscillators 1, Fig. 4, are keyed according to the code by a commutator 1<SP>1</SP> which is displaced according to the angular value through a coupling 2 which may multiply the movement by 32 or be a regulable device. A phasing device 3 keying further frequencies is provided to overcome the ambiguity introduced by the coupling by indicating the zone in which the angle occurs. The frequencies which are mixed and modulated for transmission in units 4 and 4<SP>1</SP> are demodulated in a level regulated demodulator 5, Fig. 5, and separated for individual detection in detectors 7 by band-pass filters 6. Constitution of the F and G voltages is effected by units 9 of resistances in geometrical progression and they are applied via dephasing units 11 to potentiometer 10<SP>11</SP>. The phasing signals are applied with signals from commutator section 12 driven through <SP>1</SP>/ 32  reduction gearing 13 by the motor 10 to a coincidence unit 14 to act conjointly with the potential on the potentiometer wiper to set the desired angle. In a modified arrangement described with reference to Figs. 6 and 7 (not shown), two rotary commutators one of which is driven through a multiplying step-up gearing transmit separate coded information for coarse and fine adjustment and the receiver comprises "coarse" " and " fine " circular potentiometers, the coarse adjustment equipment only being brought into service when the error voltage exceeds a predetermined threshold value. Electromechanical relays or electronic devices may be used in the binary code voltage converters according to the speed of response desired.
