Title: Improvements in or relating to colour television transmitters
IPC: H04N9/72
Filed: 1969-06-18
Abstract: 1,208,704. Colour television. MARCONI CO. Ltd. 18 June, 1969 [28 June, 1968], No. 30967/69. Heading H4F. In a colour television transmitter the video signals to be transmitted are distorted, in order to compensate for distortions which will later be introduced by the transmitter chain, by an arrangement including three non-linear video paths. The video signals are fed via an input amplifier 1 with associated D.C. restorer 2 to a frequency power distributer 3 which provides at U 1  and U 2  two phase opposed outputs. These outputs are fed as shown to the non-linear video paths 4, 5 and 6. In path 4 the signal is pre-distorted independently of its frequency to obtain correction of differential gain in non- linear distorting circuit RD4 which comprises a plurality of parallel circuits each including a distorting passive element, e.g. a diode, and an additional parallel circuit of adjustable attenuation (Fig. 2, not shown). In path 5 the signal is distorted by a non-linear distorting arrangement RD5 (similar to RD4) which is followed by distorting means QL having a linear phase characetristic providing compensation for differential phase correction. Circuit QL comprises an inductance, a capacitor and a resistance in parallel (Fig. 3, not shown) and provides a signal vector which is 90 degrees out of phase. In path 6 the signal is distorted by a non-linear arrangement RD6 (similar to RD4 and RD5) and is then subjected to linearity correction by means of a band clipping circuit QF comprising two band-rejector circuits (Fig. 4, not shown) which have a linear phase characteristic over the whole signal band. To decouple the three paths, low input impedance amplifiers 40, 50 and 60 are connected as shown. Delay lines T 1  and T 2  compensate for the time delays introduced by circuits QL and QF. The output from T 1  is in phase quadrature to the output from 50 and thus network 7 combines the two distorted signals without any effect on the amplitude of the signal. Combiner 8 is designed to provide an impedance match with coaxial line 9 leading to the transmitter chain.

Title: Improvements in or relating to the improvement of mineral or lubricating oil by treatment with solvents
IPC: C10G21/20
Filed: 1933-11-08
Abstract: Lubricating and other mineral oils are freed from non-paraffins by warm or cold extraction with chloraniline.  A diluent, e.g. pentane, liquefied propane, ethane, butane, isobutane, ethylene, or other normally gaseous hydrocarbon, light petroleum naphtha, kerosene, or gas oil may be present, refining by clay, sulphuric acid and/or alkali may follow, and the extraction may be repeated. Gaseous propane may first be dissolved in the oil; or a mixture of oil and liquid propane may first be cooled by flashing so as to precipitate asphaltic matter.  Extraction temperatures of 20--160 DEG  F. are specified.  For example, 1 part of lubricating <PICT:0426221/III/1> oil from a tank 10, 7 parts of liquid propane from a tank 14, and 1 part of chloraniline from a tank 17, are passed to a mixer 13, a heater 20 in which the temperature of the mixture is raised to 80 DEG F. and the pressure to 125 lbs. to ensure complete miscibility, a cooler 22 where the temperature is reduced to 35 DEG  F. by flashing to cause phase separation, and a separator 27 in which an upper raffinate layer and a lower extract layer form.  The raffinate is passed by a pipe 44 to a tower 46 in which the propane is vaporized by steam coils 47 and residual chloraniline is removed by propane gas, carbon dioxide, or steam introduced by a pipe 48; the clean oil is then passed by a pipe 49 to a storage tank 50. The vapours from the tower 46 are led to a condenser 52 and a separator 53, the liquefied chloraniline being pumped through a conduit 41 to the tank 17, and the gaseous propane being compressed through a pipe 25 and a condenser 26 whence as liquid it returns to the tank 14.  The chloraniline solution of non-paraffins is withdrawn from the extractor 27 through a pipe 28, and pumped through a tower 30 heated by steam coils 31 so as to vaporize the chloraniline and residual propane; steam or propane gas may be introduced by a pipe 31<a> to remove the last trace of chloraniline.  The extract is led by a pipe 33 to a tank 34.  The vapours are passed to a condenser 36 and a separator 38, whence chloraniline and any water are pumped through pipe 41 to the tank 17, and propane is led through a pipe 42, a compressor 43, and the pipe 25 to the condenser 26 and tank 14. Specification 410,175 is referred to.

Filed: 1928-10-26
Abstract: 324,639. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Oct. 26, 1928. Two-way repeating systems.- Suppression of echo currents is ensured by the arrangement in each path of one or more multiple winding transformers which are controlled by incoming currents in such a way that the transformer of only one path are capable of transmission at a time. Fig. 1 shows the arrangement of pair of transformers TW, TW<1> and TE. TE<1> in each path, the windings 3, 4 and 3<1>, 4<1> being normally in aiding relation, but when relay RE operates due to transmission through the other path, a short-circuit is removed and the windings 3, 4 and 3<1>, 4<1> are in opposite relation, thus preventing transmission through this path. The capacity of the leads from the windings to the relay contact may be balanced by a similar capacity connected across the contact.. Fig. 5 shows the arrangement of a hybrid transformer 7, 10 with balancing networks 8, 9 and 11, 12 in each path. Incoming currents over the line 1 operate a control device 19 through a rectifier 17 and low-pass filter 18 to alter the impedance of the network 9 by means of the coupled output winding 25, thus unbalancing the bridge and allowing transmission through the transformer 7. At the same time a disabling voltage is applied across a resistance 27<1> in the grid circuit of the rectifier 17<1> connected to the return path to prevent the transformer 10 being tendered effective. Delay circuits 26, 26<1> are provided.
