Patent GB-671919-A (GB)
Title: Improvements in or relating to processes for the production of refractory metal carbides
IPC: C01B31/30
Filed: 1948-02-27
Abstract: In making powdered refractory metal carbides by reacting carbon, e.g. carbon black made by the incomplete combustion of organic liquids or gases, with one or more refractory metals or compounds capable of liberating the metal or metals during the reaction, the initial mixture of the powdered constituents is mixed by malaxation into a thick paste with a liquid having a dispersing action on the carbon grains, the liquid being such that it can be evaporated without leaving any residue, and the mixture is agglomerated by compression and heated at a sufficiently low temperature and for a sufficiently short time to prevent the agglomerates from acquiring a cohesion such that their passage through a crusher is necessitated to produce a powder.  A lubricant, e.g. petroleum jelly, liquid paraffin and stearic acid, may be incorporated in the mixture prior to compression. Petroleum spirits or oils, benzene hydrocarbons, alcohols &c. may be used in making the paste.  In the example tungsten and purified carbon black are mixed into thick paste with petroleum spirit and the latter is eliminated by heating in vacuo at 40 DEG C.  The powder is compressed into briquettes which are then immersed in a graphite luting in a graphite crucible and heated to 1400 DEG C. for 1 hour in an hydrogen atmosphere.  After baking and cooling the briquettes are reduced to powder by the application of a few shocks or light pressure by hand.  Specifications 626,653 and 647,710, [Group II], are referred to.

Title: Improvements in or relating to moving body guiding systems
IPC: G05D1/02
Filed: 1954-03-05
Abstract: 757,048. Locating bodies by radiation beams. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 5, 1954 [March 6, 1953], No. 6592/54. Class 40 (3). A system for determining whether a moving body lies in a particular plane comprises a pair of photo-transistors responsive to light transmitted by the body and symmetrically located with respect to the plane, the outputs of the two transducers being so combined as to indicate when the source is outside the plane. A phototransistor of the type which may be used in apparatus according to the invention is shown in Fig. 1 and consists of a germanium plate 1 having one plane face on to which light is focused and the other slightly concave. A metallic point is applied to the centre of the concave face and connected through a milliammeter 4 to the positive pole of a battery 3. The negative pole of the battery is connected to the edge of the germanium plate. The transistor is said to be extremely sensitive to divergence of the point of impact of light from the centre of the plate. The detecting system is shown in Fig. 2 in which the body P whose position is to be located is situated off the plane X<SP>1</SP>, X on opposite sides of which are situated the transistors T1, T2. The signals produced by the transistors are fed in opposition to a D.C. amplifier A. The amplifier produces a signal which depends on the difference of the two transistor signals and controls a radio transmitter E which transmits a signal informing the moving body whether it is in the plane X<SP>1</SP>, X or not. In a modification, Fig. 4 (not shown), to identify on which side of the plane the object has deviated the two light beams are interrupted alternately by synchronized shutters. The duration of the interruption of the two light beams however differs. The outputs of the two transistors are then displayed on a cathoderay tube as two series of pulses, the pulses in one series being shorter than those in the other. The relative amplitude of the two sets indicates in what direction the body has deviated from the plane. The receiving surfaces of the photo-transistors may be mounted at an angle other than 90 degrees to the reference plane (Figs. 8 and 9, not shown).

Title: Improvements in or relating to hot water heating plant
IPC: F01K7/34
Filed: 1937-03-08
Abstract: 493,548. Heat - storing apparatus. RUTHSACCUMULATOR AKTIEBOLAG. March 8, 1937, No. 6812. Convention date, March 7, 1936. [Class 64 (ii)] In a water-heating plant of the kind having a heat accumulator 11 and wherein steam is supplied from a power plant by a long distance pipe 5, e.g. over 100 yards, the water is heated in a preheater 7 by steam from the pipe 5, and the amount of such steam is regulated by a valve 6 at the end of the pipe 5 adjacent the power plant and controlled in accordance with the load on the plant, while the flow of water through the preheater is controlled by a second valve 15 controlled in accordance with the steam pressure at the outer end of the long distance pipe 5 or in accordance with the temperature of the heating water. Steam passes from a boiler 1 through a turbine 2 or a byepass valve 4 to a low pressure line 3, and condensed steam from the outer end of the pipe 5 is returned to the boiler by a pipe 8. An accumulator 11 is connected between a forward flow pipe 9 and a return pipe 10 for the heated water, which is circulated by a pump 12 through the preheater 7. Discharge of water in the accumulator is controlled by valves 13, 14 so that the temperature of the water remains constant. Several heating units may be connected to one power plant by separate long distance pipes each provided with a throttling valve adjacent the power plant so that the units may be heated either together equally or each in turn. When the steam supply through the long distance pipe 5 and the pressure therein falls off, the temperature setting of the water flow valve 15 may be lowered by a temperature regulator 45 in the pipe 9 set to predetermined temperatures by a device 44 in accordance with the pressure in the outer end of the pipe 5. The water thus heated to a lower temperature, e.g. 120‹ C., may be stored in a separate accumulator 35 and may later be circulated and heated to the higher temperature, e.g. 150‹ C., when the steam supply permits. Cold water may be added by a pipe 37 to the hot water flow pipe 9.

Patent GB-421049-A (GB)
Title: Improvements in or relating to the extraction of oils
IPC: C11B1/10
Filed: 1933-03-09
Abstract: Oil is extracted from animal or vegetable cellular materials such as nuts or sesam<\>ae seeds by comminuting, treating with up to 15 per cent of a liquid miscible with the oil to be extracted but not with water, e.g. a vegetable oil such as arachis or a hydrocarbon oil such as paraffin and with 30 per cent or more of water, and removing the mixture of liquid and extracted oil which rises to the surface.  The ground material may be heated before treating, and the water may be heated, and may contain a dissolved salt such as common salt to increase its specific gravity. Further quantities of oil may be extracted by passing hot air through the residual mash, or by fermentation with the aid of, for example, diastase, with, if desired, simultaneous passage of hot or cold air through the mass; any oil remaining after such treatment being pressed out.  In treating sesam<\>ae seeds, glycerine may be added during or after the treatment with water. To prevent emulsification the water may be softened.  The albumens or proteins which impede the flow of oil to the surface may be coagulated by means of citric acid, Irish moss, or isinglass.  The residue is dried and pressed to produce an animal food, diastase being added if not already present.  In an example, decorticated, finely ground nuts are heated up to 180 DEG  F., mixed with 4--8 per cent of paraffin oil and 2--4 per cent of common salt, and agitated with boiling water in the proportion of 1--3 lbs. of water to 1 lb. of nuts, the extracted oil rising to the surface. Further quantities of oil are extracted by treatment with hot air. According to the first Provisional Specification, the fermentation is produced by inoculating with lactic-acid-producing bacteria, e.g. by adding brewers' malt or barley, with, if desired, cellulose-consuming organisms, the lactic acid produced being neutralised with calcium or magnesium carbonate.ALSO:Animal food rich in sugar, proteoses, and peptones is obtained by drying and pressing the residue obtained in an oil extraction process in which animal or vegetable cellular materials such as nuts or sesam<\>ae seeds are ground, treated with water (which may be heated and may contain a dissolved salt such as common salt to increase its specific gravity) and with a liquid miscible with the oil to be extracted but not with water, e.g., arachis or paraffin oil, and, after removal of oil rising to the surface, treated further with hot air, or fermented with the aid of diastase. Diastase is added before drying, &c., if not already present.
