Abstract: The invention relates to an apparatus for atomizing a molten material, by disintegration of a stream of the molten material by fluid jets directed under high pressure against said stream, a first and a second fluid jet generated at opposite sides of the stream being converged towards a point of intersection lying aside of the stream of molten material, said first fluid jet being spread out in a plane intersecting the stream of molten material at an acute angle, said second fluid jet extending within +/-10 DEG  relative to the original direction of the stream of molten metal. The invention is characterized in that said second fluid jet is imparted the shape of a curved curtain with its concave side facing the stream of molten material, and the second nozzle, in a plane perpendicular to the pouring direction, is curved with its concave side facing the casting opening and directed essentially in the same direction as said casting opening.

Abstract: 1456260 Crystallizing fructose SUOMEN SOKERI OSAKEYHTIO 9 Dec 1974 [28 Jan 1974] 53056/74 Heading B1G [Also in Division C2] Fructose crystals having a crystal size of 200 to 600 Ám are obtained by crystallizing fructose from an aqueous solution thereof, containing at least 90% by weight of dry substance of which dry substance at least 90 percent by weight is fructose, in a process which comprises (a) providing such a fructose solution (b) adjusting the pH of said solution to 4.0-6.0, preferably 4.5-5.5, (c) bringing the aqueous fructose solution to a temperature at which it is saturated with respect to fructose, (a) adding fructose seed crystals to the solution, (e) lowering the temperature of the resulting mass at a controlled rate to cause the mass to be supersaturated with respect to fructose and to bring about an increase in the crystal size of the seed crystals without substantial formation of new fructose crystals and (f) separating the fructose crystals from the mass when the crystal size is 200-600 Ám. The process may be carried out continuously using as seed crystals, crystals taken from a previous crystallization and recrystallization may be accelerated by blowing warm dry air on to the surface of the mass to evaporate water therefrom during crystallisation. The rate of crystallisation of fructose may be increased by the addition to the solution of 2-4% by weight, based on the sugar solids, of methanol, ethanol, and/or isopropanol.

Abstract: 1525991 Explosive compositions IRECO CHEMICALS 9 Jan 1976 [20 Jan 1975] 00782/76 Heading C1D An aqueous gel or slurry explosive composition comprises an oxidizing salt dissolved in an aqueous phase, a solid fuel or a liquid fuel or both, a thickener, and, as a sensitizer, at least 20% by weight of calcium nitrate together with at least 3% by weight of sulphur. The oxidizing salt in addition to the calcium nitrate may be ammonium, alkali metal, or alkaline earth metal nitrate or perchlorate. The fuel may be finely divided aluminium, gilsonite, coal, wheat grain, methyl alcohol, ethylene glycol, formamide, or fuel oil. The thickeners referred to are guar gum, which may be of reduced molecular weight, polyacrylamide, flours, and starches. In order to reduce the density of the composition, gas or air may be introduced by the addition of sodium nitrite, hollow glass or plastics spheres, or foamed plastics beads. Examples show that the combination of calcium nitrate and sulphur is a better sensitizer than a combination of sodium nitrate and sulphur, and is cheaper to use than paint grade aluminium.

Abstract: A radiation sensitive plate comprises a metallic substrate having a surface coated with a radiation sensitive layer comprising a quaternary ammonium salt. The quaternary ammonium salt is of the type which will accept at least one electron on exposure to radiation to form a substance capable of causing metal to be deposited onto said substance from an electroless plating solution in contact with said substance and comprising a salt of said metal and a reducing agent.  The layer may include a chemical sensitiser, a spectral sensitiser, a polymeric binder, a surface active agent and/or a development accelerator. The preferred chemical sensitisers are aryl substituted glycollic acids or salts or ethers of such acids, A lithographic printing plate is produced by image-wise exposing the plate, contacting the plate with an electroless plating solution and, if necessary, rendering the resultant image areas more oleophilic and the resultant non-image areas more hydrophilic.

Abstract: The bilaminar yarns consist of polyethylene terephthalate and crosslinked polybutylene terephthalate with a melt viscosity of at least 2000 poises at 260 DEG C. The polyethylene terephthalate constitutent, seen in section, partially surrounds the crosslinked polybutylene terephthalate constituent. The die used for spinning is provided with a distribution plate (1) pierced with conduits (4) whose axes are eccentric in relation to the axes of the pre-holes (3). The polybutylene terephthalate is delivered via the conduits (4) and, in the pre-holes, is surrounded by the polyethylene terephthalate travelling from the gap (8) separating the distribution plate from the die (10). The crimping frequency and stability are better than when it is polybutylene terephthalate that surrounds polyethylene terephthalate.   These bilaminar yarns find widespread use in the textile industry. <IMAGE>

Abstract: A power plant comprises an internal combustion engine, (Diesel engine), a compressor for supercharging the engine and a turbine for driving the compressor. The turbine is fed in parallel by the exhaust conduit of the engine and by a passage communicating with the compressor outlet. The passage is divided into two parallel arms. The first arm has a throttle. The second arm is connected to the primary zone of an auxiliary combustion chamber via orifices of a cross-section such that the pressure drop produced between the upstream and downstream ends of the orifices of the second arm is the same as the pressure drop produced between the upstream and downstream ends of the throttle of the first arm. The combustion chamber is fed by a fuel supply system entering the primary zone in the region of the turbulence produced in this zone by the arrival of air through the orifices, so that a complete and stable combustion is achieved in the auxiliary combustion chamber.

Abstract: To permit high-temperature differential cross flow of an initially cool, heat absorbing medium and an initially hot, heat releasing medium, with temperature differences in the order of 1000 DEG  and higher, and to prevent localized thermal overload, the heat exchanger is a two-stage heat exchanger, with plate packages (5, 6) which are serially passed by the media, typically gaseous media. The first package (5) forms a preheater stage and the second package (6) forms a final heater stage. Connecting ducts (9, 10) are provided and so arranged that the initially hot fluid medium is conducted through flow channels in the second heater stage which receives heat absorbing medium which has already passed through the preheater stage, so that it has already been preheated, thereby reducing the temperature difference between the preheated heat absorbing medium and the initially hot, heat releasing medium. The heat releasing medium, having been cooled in the final heater stage, is then passed to the preheater stage where it transfers heat to the initially cool heat absorbing medium, which is directed to its inlet. The plate packages comprise flat plates, formed with corrugations, for example extending at an angle of 30 DEG  with respect to the flow direction of the fluid.

Abstract: In the input and output air channels (9,10) in the fire cells (3,4) are positioned self-acting check valves (13) over which normally rules a pressure drop in the air flow direction produced by the fans (11,12). This pressure drop maintains the check valves open, but they close au tomatically when the pressure drop over them ceases. Also in the input and output air channels are fitted other, normally open valves (21) with an operating device which has a heat sensor. These valves are automatically closed when the channel temp. exceeds a specific value and are also formed as check valves. When they are operated for closure, they automatically are activated towards their cut-off posn. by the flow in the channels which tends to open the first check valves (13).
