Abstract: A fish processing machine includes a fish body feeder, a decapitator, a belly filleting and viscera removing device, and a dark-colored flesh removing device. The fish body feeder is designed to transport fish bodies onto trays while aligning all of the fish bodies in a uniform direction. The dark-colored flesh removing device separates the ordinary flesh and dark-colored flesh of the fish body efficiently.

Abstract: A decolorized oyster extract concentrate is formed by an adsorption purification treatment using a specific inorganic lamellar magnesium phyllosilicate compound and a concentration treatment. Coloring components can be effectively removed without substantial reduction of the contents of taste components and nutrients. The decolorized oyster extract concentrate is very valuable as a seasoning or healthy food.

Abstract: Dust containing high-temperature gas exhausted from an electric steelmaking furnace is directed through scrap preheaters, wherein scrap that is to be charged into said electric furnace is preheated. The absorption of some of the heat from the exhaust leaving the electric furnace by the scrap, therefore, decreases the amount of electric power required for melting the steel scrap and also shortens the time required for steelmaking. Exhaust gas after preheating of the scrap is contaminated with incidental malodorous materials, e.g., paint and oil fumes, and is directed through a gas scrubber followed by a wet-type electric precipitator to remove these contaminants before release of cleaned exhaust gas into the atmosphere. A flow of alkaline aqueous solution of a deodorant solvent in the gas scrubber removes malodorous substances from the exhaust gas, simultaneously causing a drop in the gas temperature to a predetermined controlled value while generating a constant supply of saturated water vapor.

Abstract: A hot gunning robot system moves a gunning nozzle along a vertical center line of the furnace and changes the swiveling angle of the gunning nozzle to perform mending of all interior side and bottom surfaces of the furnace. The system comprises a shifter transferring the nozzle carrier from a housing position to a mending position in the furnace. The shifter has parallelogram-links and an actuator which actuates the links to move the nozzle carrier in an upright constant orientation. A water feeding tube is fitted on a vertical feeding pipe to mix lining material powder with water to obtain a sludgy lining material introduced into the gunning nozzle smoothly by guide vanes provided in a cylindrical nozzle supporter. The nozzle carrier is partitioned into a driving chamber and an air chamber and both of chambers are air cooled. A driving system and bearing system for the vertical feeding pipe is protected from the heat of the furnace.

Abstract: This disclosure relates to a system for preheating scrap before charging in an electric furnace and for preventing the release of malodorous or noxious gas. The system includes a first duct leading from the furnace exhaust gas outlet to a chimney; a branching duct is connected in the first line for passing part of the gas to the chimney and for diverting the remainder of the gas to a scrap preheater. After preheating the scrap, the diverted gas is recirculated back to the first line at a junction which is adjacent the furnace outlet. The system further includes gas combustion means connected in the first line between the junction and the branching duct, and a heat equalizer-accumulator in the first line between the combustion means and the chimney. The system may further include a heat exchanger connected in the first line downstream of the branching duct and a second line for passing the diverted gas through the heat exchanger after it leaves the scrap preheater.

Abstract: When an alkali such as an alkali metal bicarbonate or carbonate is intimately mixed with bauxite or other alumina-containing raw material at an Al.sub.2 O.sub.3 /Na.sub.2 O molar ratio of from 1/1 to 1/3 and the mixture is molded into granules, then calcined and extracted with an aqueous medium, the alumina component can be recovered in a high yield in the form of an aqueous solution of an alkali metal aluminate. The alkali component is not substantially contained in the residue left after recovery of this aqueous solution.

Abstract: A process for recovery of nitric acid comprising incorporating or absorbing waste nitric acid and/or a nitrate in an oil-absorbing inorganic carrier and forming a nitrate-carrier granule containing water in the form of a hydroxide, a hydrate or adsorption moisture in an amount sufficient to generate a vapor of nitric acid stably and being substantially non-sticky at a decomposition temperature of the nitrate; heating the formed granule while keeping the substantially non-sticky state in the granule to decompose the nitrate in the granule to a vapor of nitric acid; and recovering the generated vapor of nitric acid is disclosed. According to this process, nitric acid can be directly recovered from waste nitric acid or a nitrate in the form of a vapor of nitric acid without substantial generation of nitrogen oxide gases by using a cheap and easily available inorganic carrier.
