Patent GB-460906-A (GB)
Title: Improvements in or relating to processes for the separation of hydrocarbon mixtures
IPC: C10G21/00
Filed: 1935-08-06
Abstract: Mixtures of hydrocarbons such as mineral oils are separated into fractions of different specific gravity by distributing the oil uniformly over the cross-section of a vessel filled with a solvent of lower specific gravity than the oil, whereby after standing the soluble hydrocarbons form layers or strata of different specific gravity and an insoluble fraction settles at the bottom, the layers being then withdrawn and freed from solvent.  The treatment is effected without the application of heat.  A tall column c, provided with a jacket maintained at 15--20 DEG  C., is filled to half its height with benzine, acetone, or a mixture of ether and alcohol admitted from a tank a.  Crude <PICT:0460906/III/1> mineral oil is then admitted to fill the column through a spray distributer h from a tank b maintained at 60 to 70 DEG  C. to promote easy flow of the oil.  The constituents of low specific gravity dissolve first and remain in the upper layers and the heavier constituents sink through the solvent yielding further layers of increasing gravity.  After standing several hours, the column is submitted to pressure, e.g. 3 atmospheres, generated in a vessel m.  A valve in an overflow tube i is then opened and liquid from the top of the column flows into a vessel k.  After admitting further solvent at the base of the column if necessary, and a further settling period, the layers are drawn off through taps f and the separate layers freed from solvent.  Insoluble substances such as asphalt are withdrawn through a tap g.  The fractions obtained may be further treated with sulphuric acid, lime and fuller's earth.

Title: Improvements in or relating to television receivers
Inventor: WADSWORTH ANTHONY CHARLES
IPC: H04N5/46
Filed: 1965-05-26
Abstract: 1,105,384. Converting. E. K. COLE Ltd. 23 May, 1966 [26 May, 1965], No. 22296/65. Heading H2F. [Also in Division H4] The invention relates to an arrangement for maintaining the focusing voltage for a television receiver display cathode-ray tube constant when the receiver is switched from one scanning standard to another. When operating according to a first standard (e.g. 405 lines) with switch SWb, Fig. 2, in position B, the focusing voltage is produced from pulses occurring in the line output transformer T1 by means of rectifier FR the actual voltage being adjustable by means of a known circuit (Fig. 1, not shown) including an adjustable transformer T2 which operates to vary the effective pulse voltage across the rectifier. When switched to the second standard, e.g. 625 lines, SWb in position A, a source of further pulses from an additional winding on the transformer T1 is introduced in series with the pulses from transformer T2 and so poled that they add algebraically and thus increase the pulse voltage across the rectifier so that the focus voltage is increased by an amount which compensates for the inherently lower focus voltage otherwise available during 625 line operation. The display tube may be a shadow-mask colour tube.

Title: Process for the surface treatment of finely divided oxides or mixtures of oxides
IPC: C09C3/08
Filed: 1956-07-23
Abstract: The finely-divided oxides of metals and metalloids having free -OH groups on the surface, especially silica, are treated in a substantially or completely anhydrous state with an alcohol vapour, preferably in a fluidized bed.  Alcohols especially suitable are those which contain not more than 20 carbon atoms, e.g. methanol, n-butanol.  Particularly stable products are obtained if alcohols capable of forming esters of low hydrolysis constant are used, e.g. partially esterified or etherified polyhydric alcohols, such as monoalkyl glycols, especially monomethyl glycol.  A volatile esterification catalyst, preferably hydrogen chloride, may be present.  The number of initial -OH groups present may be increased by treating the oxides with superheated steam.  The products are very suitable for incorporation in, for example, rubber and other organic media. Mixed oxides may be treated in the same way.

Filed: 1928-08-09
Abstract: 321,935. Sharma, D. N. Aug. 9, 1928. Television,; copying-telegraphs.-The pictures to be transmitted are recorded on a film which is both light-sensitive and fluorescent. The fluorescent and photographically sensitive film may be coated with an emulsion containing double salts, such as (1) a sulphate or sulphide of manganese, cadmium or zinc together with (2) silver bromide or iodide, by either precipitation or crystallization from a common solution. These salts may be incorporated with the material of the film or may be applied to it as a coating. At the transmitting station (Fig. 1, not shown) the fluorescent kinematographic film, after being inscribed with a sound record and picture record, passes through developing, fixing and washing tanks and an electrically heated drying chamber, stirrers and a drying fan being provided. The film F, Fig. 2, then passes between a cathoderay tube I and a light-sensitive cell 7. A pencil of cathode rays is caused to oscillate in a direction transverse to the direction of movement of the film. fluorescence is excited at the point of incidence of the rays, and affects the lightsensitive cell 7, or not, according to the density of the photographic record at that part of the film. Simultaneously the sound record influences a light-sensitive cell 11, and the output of the cells 7, 11 modulates the two different carrier frequencies. At the receiving station the picture signals influence a pencil of cathode rays which oscillates either in two dimensions so as to reproduce the picture on a fluorescent screen, or in one dimension so that the emergent Lenard rays affect a moving photographic film. 'The intensity of the pencil is varied under the influence of deflecting electrostatic plates to which the received signals are applied. The pencil normally passes through an aperture in a screen but is deflected thence by the signals.
