Title: Improvements in or relating to the cooling systems for internal combustion engines
IPC: F01P3/22
Filed: 1932-09-17
Abstract: 410,199. Cooling cylinders. FAIREY AVIATION CO., Ltd., Cranford Lane, Hayes, Middlesex, and FORSYTH, A; G., Venlaw, Burdon Lane, Cheam, Surrey. Sept. 17, 1932, Nos. 25936/32 and 3122/33. [Class 7 (ii).] A cooling system for aircraft engines is provided with a water-cooling radiator 14 of such size as to effect adequate cooling under normal conditions and a steam-condenser 17 which becomes operative under abnormal conditions, the condenser being located behind the radiator or incorporated in the wing or fuselage structure in known manner so that only the water-cooling radiator offers head resistance. Liquid and steam from the engine jackets 10 pass by a pipe 11 to a steam separator 12 whence the liquid descends to the radiator and steam passes through a dome 15 to the condenser, which is preferably formed of two similar triangular parts 18, 19, Fig. 3. The water from the radiator is returned by a pump 24 to the jackets and the condensate is delivered by a pump 21 back to the separator. In a modification, Fig. 4, a centrifugal steam separator 26, as. described in Specification 315,007, [Class 23], is employed, and the condenser is constituted by headers 31 and conduits 32 in the wing surface. The condensate is fed into the radiator 27, and the radiator may be movable into and out of the air stream as described in Specification 252,082, [Class 29]. The quantity of the water circulating through the radiator may be regulated by a valved byepass pipe.
Patent GB-439380-A (GB)
Title: Improvements in the manufacture and production of nitrogenous condensation products
IPC: C07D213/82
Filed: 1934-09-10
Abstract: Monoacylbiurets are manufactured by reacting allophanic acid chloride with carboxylic acid amides, e.g. formamide, acetamide, trichloracetamide, cinnamic amide, benzamide, toluic amides, chlorbenzamides, methoxybenzamides, pyridinic acid amides, quinolinic acid amides, phthalic amides, diphenylcarboxylic acid amides, urea, phenylurea, benzoylurea and urethanes.  When the melting point of the amide is not too high, the reaction may be carried out by fusing the components together; in other cases inert solvents or diluents, e.g. benzene, toluene, chlorbenzenes or nitrobenzene, are employed.  In some cases it is advantageous to add substances which combine with hydrogen chloride, e.g. sodium acetate or sodium, potassium, calcium or magnesium carbonate, and also metal compounds, such as copper salts, which facilitate the splitting off of hydrogen chloride but which do not cause condensation of the allophanic acid chloride with the diluent employed.  The products may be converted into 4 : 6-diketo-1 : 3 : 5-triazines by splitting off water with the aid of alkaline condensing agents, e.g. caustic soda or potash solution, milk of lime, sodium alcoholate, ammonia, sodium or potassium carbonate.  These triazine compounds may be employed in the pharmaceutical industry or for the preparation of dyestuffs, By the action of phosphorus pentachloride they may be converted into the corresponding dichlorides.  In examples, allophanic acid chloride is reacted with: (1) benzamide in the presence of monochlorbenzene, yielding benzoylbiuret, which is treated with caustic soda solution to produce 2-phenyl-4 : 6-diketo-1 : 3 : 5-triazine; (2) p-toluic acid amide in dichlorbenzene, yielding p-toluylbiuret, which is treated with caustic potash solution to produce 2-tolyl-4 : 6-diketo-1 : 3 : 5-triazine (3) p-chlorbenzamide in monochlorbenzene, producing p-chlorbenzoylbiuret; or with other halogen substituted benzamides or methoxy- or ethoxybenzamide; (4) cinnamic acid amide in trichlorbenzene, yielding cinnamoylbiuret; (5) monophenylurea in monochlorbenzene, producing phenylallophanylurea, C6H5NHCONHCONHCONH2, or with urea or benzoylurea; (6) urethane in monochlorbenzene, yielding allophanylurethane, or with the methyl or phenyl ester of carbamic acid.  Specification 436,657 is referred to.

Abstract: 283,091. Pontoppidan, C. Oct. 8, 1927. Reducing cements; ball mills.-In grinding cement and like substances, a liquid or other substance which will be evaporated by the heat produced by the grinding is added to the cement during the last stage of the grinding process to keep the temperature of the cement below the temperature at which the cement is inclined to adhere to the surfaces, grinding bodies, &c. in the mill. The liquid may be supplied to the cement &c. in an atomized or finely distributed state; and chloride or sulphate of lime, tannin, or other substance it is desired to supply to the material being ground may be suspended or dissolved in the liquid used for regulating the temperature. The liquid is introduced into the grinding-mill through one of the ends of the mill,. preferably the discharge end. Fig. 1 shows a. tube mill r with three grinding-chambers 1, 2, 3 in which water is supplied to the last chamber 3 by means of a pipe l passing through the trunnion d at the discharge end of the mill. The inner end of the pipe terminates in a spreader m, and the outer end is connected to a pump j supplied with water by a valved pipe h. Supports n are provided inside the mill from the pipe l, which rotates with the mill. Thermometers o, p are provided in the spout of the storage bin a and delivery pipe f to actuate optical or acoustic signal devices when the permissible temperature limits have been reached. In Fig. 2, the liquid is supplied through the inlet end of the mill by a pipe r which passes through the trunnion t, and is then extended radically out through the trunnion and passes parallel to the axis of the mill to the second grinding-chamber 2. The end portion s of the pipe extends diametrically across the mill and is provided at its centre with a spreader or atomizer m. The liquid may be supplied to several different zones or chambers of a mill, or to different zones of the same chamber.

Abstract: 1433483 Fluidized beds; boilers PLESSEY CO Ltd 19 April 1973 [8 June 1972] 26710/72 Headings F4U and F4A [Also in Division B1] The resistance to gas flow into a fluidized bed in a central heating boiler differs at different portions of the bed whereby the degree of fluidization may be varied by varying the fluidizing gas pressure. In a first embodiment, Fig. 1 (not shown), the bed support comprises a metal plate formed with holes which differ in concentration in different areas of the plate. In a second embodiment, Fig. 2 (not shown), the bed support consists of a metal plate formed with equally spaced and sized apertures over each of which is disposed a conical baffle. The spacing of the baffles over the apertures differs at different areas of the plate. In a third embodiment, Fig. 3, a water jacket 54 is formed with inwardly projecting portions 62, 66 which overlap to provide an aperture 68 and which support the fluidized bed 70.

Abstract: 782,972. Cathode ray tubes. KRAWINKEL, G. H. Sept. 29, 1953 [Oct. 6, 1952], No. 26729/53. Class 39(1). An electronic switch comprises a target electrode consisting of an insulating base carrying first and second secondary emissive electrodes E. C, Fig. 2, a secondary electron collector A, one of the electrodes E, C being connected to a source of variable potential so that when there is a potential difference between E, C the secondaries cannot pass to A while when their potentials are equal secondaries can pass to A. The target comprises two sets of interleaved strips E, C evaporated on to insulating plate F. Secondary emission collector A is formed on one side of insulating plate D, on the other side of which is screening electrode H which screens the primary beam from the secondary emission collector A. In operation if strips E and C are at the same potential secondaries can pass to collector A but if E and C are given different potentials secondaries from the more positive strips are blocked by the negative strips while secondaries from the negative strips are captured by the positive strips so that no secondaries flow to A ; this is the basic switching action of the invention. There may be three or four sets of strips E, C for further switching control. The primary electron beam can be modulated and one or more further stages of multiplication can be provided as by providing a secondary emissive electrode, Fig. 5, between E, C and A. The tube can be used as a line selector in automatic telephone systems, or as a computer. There may be a large number of switches in one tube successively struck by the electron beam.
