Abstract: 590,024. Separating liquids from solids. ATTWOOD, R. G., and MILLAR'S MACHINERY CO., Ltd. April 9, 1945, No. 8750. [Class 46] Apparatus for removing liquid from a slurry comprises an open link for the slurry, and a plurality of strainer elements enclosed within one or more containers for sand, located in or in communication with the tank, each container being relatively small compared with the tank, and means being provided for connecting the strainer elements to suction to remove air and liquid from the tank. As shown in Figs. 1 and 2, a tank 1 is divided by a wall 4 into two compartments 2, 3 and is provided with a compartment 6 containing a filter bed 9 of sand. Pipes 10 to which strainer elements 11 are connected are located within the filter bed and are connected by pipes 12, 13 to suction-producing means 14. The elements 11 comprise each a fluted tube covered with fine brass mesh protected by a heavy perforated brass screen, one end of the tube having inlet openings. In a modification the filter bed is located along a bottom corner of the tank, by means of perforated vertical panels of brass sheet secured by angle bars. After the slurry has settled, surface water may be drawn off by means of a flexible suction pipe 34, Fig. 6, connected to a chamber 33 provided on a float 31. The float is pivotally mounted at the end of a counterbalanced arm 32 which has a swivelling bearing on the division wall 4. The chamber 33 is provided with a valve 35 comprising a slotted grid covered by a flexible apron wound around a roller, the slots being uncovered according to the movement of a ball 37 in the liquid.

Title: An improved process for the production of caramel
IPC: C12C5/04
Filed: 1930-03-19
Abstract: In a process for the production of caramel by means of sugar and ammonia, the solid sugar is mixed and liquefied with an aqueous solution of ammonia of the order of 25 per cent, the mixture is heated for a time to a temperature of 105-120 DEG  C. under pressure, the pressure is released, and the viscid product is then again heated under pressure to a temperature of 105-120 DEG  C. for such time as is necessary to reach the desired degree of colour, after which the pressure is reduced.  Volatile bye-products may be removed from the liquid in the boiler by passing steam through it. The cooled final product is a viscid composition.  A further concentration of the caramel may be effected in vacuo or by a drying process on a counterflow system.

Title: Improvements in diplexing or multiplexing video systems
IPC: H04N11/18
Filed: 1960-03-14
Abstract: 897,959. Television. COMPAGNIE GENERALE DE TELEGRAPHIE SANS F1L. March 14, 1960 [March 23, 1959], No. 8942/60. Drawings to Specification. Class 40(3). In a compatible colour television transmission system the red and blue colour component signals alternately, at line repetition rate, frequency modulate a sub-carrier wave which, during alternate picture periods, is combined with the luminance signal for transmission and also fed to a recording device from which during the intervening picture periods the recorded signals are derived, phase inverted and also combined with the luminance signal. With this arrangement the production of a dotted pattern in "black and white" receivers is prevented at the expense of a reduction by one half of the rate at which chrominance information is transmitted. It is stated that this does not particularly affect the quality of colour pictures reproduced by colour receivers. The recording device may be a magnetic drum or a charge storage tube.

Title: An improved process for maintaining the sprinkling capability of finely granular table salt
IPC: C01D3/26
Filed: 1933-03-29
Abstract: To maintain the sprinkling capability of finely granular table salt, an amount up to 7 per cent of potassium chloride is added. In the preparation from common or cooking salt, the mother liquor may be enriched in potassium chloride so that the sodium chloride separates out with the desired content of potassium chloride, or the potassium chloride may be added to the finely granular still moist salt obtained after separating the main portion of the mother liquor.  In the preparation from rock salt, the potassium chloride is added during the grinding or sieving; its action may be enhanced by adding it as a concentrated solution before the drying operation.  Anhydrous alkali or alkaline earth phosphates including disodium phosphate, magnesium monohydrogen phosphate and calcium monohydrogen phosphate may also be added to increase the action of the potassium chloride or to allow the amount thereof used to be diminished.ALSO:To maintain the sprinkling capability of finely granular table salt, an amount up to about 7 per cent of potassium chloride is added.  In the preparation from common or cooking salt, the mother liquor may be enriched in potassium chloride so that the sodium chloride separates out with the desired content of potassium chloride, or the potassium chloride may be added to the finely granular still moist salt obtained after separating the main portion of the mother liquor.  In the preparation from rock salt, the potassium chloride is added during the grinding or sieving; its action may be enhanced by adding it as a concentrated solution before the drying operation.  The taste of the potassium chloride may be diminished by addition of small quantities, e.g. 7 mg. per 1000 gm. of table salt, of sodium or potassium iodide.  Anhydrous alkali or alkaline earth phosphates including disodium phosphate, magnesium monohydrogen phosphate and calcium monohydrogen phosphate may also be added to increase the action of the potassium chloride or to allow the amount thereof used to be diminished.
