Patent SE-7713453-L (SE)
Inventor: MADL R L
IPC: F26B23/02
Filed: 1977-11-28
Abstract: A process for the air drying of a food material, such as a proteinaceous material, is disclosed wherein the drying air is heated by direct contact with a burner in such a manner that the formation of undesirable residues in the proteinaceous material as a result of combustion products from the burner is substantially reduced.  The burner is operated by feeding to it a fuel mixture containing a stoichiometric quantity of air for purposes of combustion to avoid the use of drying air for combustion.  The burner is also operated to provide a heat output which is sufficient for drying of the proteinsceous material but which does not exceed 800,000 BTU/ hr./lineal ft. of burner.  The burner is also shielded from the drying air while operated at the necessary firing rate or heat output to substantially avoid seration of the flame by the drying air.  Control of the velocity of the drying air together with the above factors substantially reduces the presence of burner combustion products in the drying air and, therefore, residues of burner combustion products in the materials to be dried.

Abstract: A microwave oscillator (14 Figure 1) is used to modulate a laser diode (12) and the resultant modulated light output energy from the laser diode is applied through an optical fibre waveguide (32) to the active solid state device (26) in a microwave oscillator circuit (28) such that the output signal from the microwave oscillator is phase locked to the modulation carried by the light energy. "On-off" switching of the microwave oscillator can be controlled simultaneously with phase locking. The solid state device 26 can be an Impatt diode, Gunn device, field effect transistor or silican transistor (Figure 4). <IMAGE>

Abstract: Highly toxic metallurgical waste materials from copper smelting and/or refining operations are processed on a cyclic basis for recovering copper values therefrom while protecting the environment from contamination. The waste materials, usually smelter flue dust and/or refinery sludge containing copper values and principally arsenic, bismuth, lead, antimony, and cadmium, as toxic values, with or without added sulfuric acid, are reacted in an autoclave at an overpressure atmosphere of O2. The resulting solution, pregnant with copper and still containing a significant amount of arsenic, i.e. from about 0.5 to about 2.0 grams per liter, is subjected to copper cementation on metallic iron to recover copper and to provide iron values in the solution while substantially eliminating residual toxic constituents, surprisingly without the evolution of arsine gas. The copper-barren but iron-containing solution is then recycled to the leaching step. The cement copper precipitate is smelted along with copper ore concentrates, while the solid residue from the leaching step is discharged to a tailings pond or the like as an environmentally safe, insoluble residue.

Abstract: The invention relates to a method of demodulating a quadphase coded data signal and a receiver for carrying out the method. The quadphase code comprises four elementary wave forms, each wave form representing two bits of the original non-coded binary signal. An elementary wave form consists of four half bit intervals, the signal corresponding to the first and the second bit, respectively, being transmitted in the first and the second half bit interval and the signal corresponding to the inverted value of the first and the second bit, respectively, being transmitted in the third and the fourth half bit interval. In a receiver according to the invention such a signal is sampled in each of the four half bit intervals. In principle all information is already available after the sampling operations in the first and the second half bit interval, but by utilizing all four samples a proper protection from noise, interference and zero level shifts is obtained. The receiver determines the difference of the samples taken in the first and the third half bit interval and the difference of the samples taken in the second and the fourth bit interval. A positive difference represents a logic 1, a negative difference a logic 0.

Abstract: In an electric storage battery having plate electrodes, the capacity and useful life is improved through uniform distribution of concentration and temperature of the electrolyte by means of electrolyte circulation. A synthetic plastic plate positioned between the plate electrodes and the housing wall of the storage battery contains a plurality of vertically extending transport tubes which are open at their upper and lower ends. The bottom portions of the transport tubes, which are immersed in the electrolyte, are connected to compressed air ducts. The compressed air is mixed with the electrolyte present in the transport tube in such a manner that the electrolyte-air mixture present therein is lifted, due to its lower specific gravity, by the electrolyte which surrounds the transport tube. The electrolyte leaving the transport tube produces continuous circulation within the storage battery, and this ensures permanent exchange of the electrolyte present between the plate electrodes.

Abstract: A gamma thermometer is supported coaxially in a bore, extending through the core of a nuclear reactor, by spring means which span the annular space between the gamma thermometer and the bore. Said spring means acts, in addition, as a thermal bridge, so that the portion of the gamma thermometer contacted by the spring means will assume a thermal temperature close to that of the bore. Since poor thermal contact between the gamma thermometer and the bore is therefore avoided, the accuracy of readings is improved.

Abstract: A respiratory mask system has a main mask 1 and an inner half mask 5. A non-return valve 9 permits respiratory gas to flow only from the half mask 5 to a space 10. Thus, during exhalation, the space 10 is charged to a super-atmospheric pressure and this pressure prevents infiltration of the surrounding atmosphere into the main mask 1. As there is no permanent open connection between a respiratory gas circuit and the space, large losses of respiratory gas due to leaks should not occur. <IMAGE>

Abstract: Cold water, for example from the ocean or a lake or a river, is used as heat input medium of a heat-pump system of large capacity, and the water is brought to freezing in order to release its freezing heat. Freezing is brought about by injecting the water into a vacuum chamber, from which the ice produced is sluiced out, while the great flow of steam produced is slightly compressed and fed into a condenser which forms the evaporation part of the heat-pump system. A simple single-stage centrifugal steam compressor is sufficient to raise the steam pressure to such a level that the steam is subsequently condensable at a temperature of 0 DEG C or slightly above, as a result of which ice formation problems in the heat-pump system are avoided. The freezing system forming the heat pump can be a simple and highly effective system as the evaporation temperature can lie as high as approximately 0 DEG C. The invention allows the use of cold lake water at 1 DEG -3 DEG C as heat-supplying medium in a heating system of large capacity with a high degree of efficiency and good economy. <IMAGE>

Abstract: Hydrogen treatment of petroleum oils takes place with the help of catalysts consisting of groundmasses with a well-defined pore-structure and containing mono-disperse small particles of oxides and their sulphides of cobalt, molybdenum, nickel and/or tungsten. Groundmasses with a bimodal, sharp, pore-size distribution are produced by the spray drying of mono-disperse brines, for ex. of silicone-dioxide. Shaped particles of groundmass are formed by extruding a mass of spray-dried particles. Mono-disperse particles of metal sulphides are formed via the processing of micro-emulsions of metal salts in a water-soluble hydrocarbon with hydrogen sulphide. The groundmass is impregnated with mono-disperse particles of metal sulphides, where after hydrocarbon and the emulsifier is removed via washing or burning.

On the other hand, when more brine is required, the siphon is made operative by closing duct (14) so that water is discharged from both chambers. <IMAGE>
