Abstract: The inner space of a drying tank 4 is made up of a mixing and drying zone MZ to mix and dry supplied material 3 by swirling the material 3 upward onto rotor blades 5 and pressing the material centrifugally against a heated cylindrical inner surface of the tank wall 2, and a drying zone DZ beneath the mixing and drying zone MZ. An upper screw conveyer 15, connected to the upper part of the mixing and drying zone MZ transfers material 3 out of the drying tank 4. A lower screw conveyer 13, connected to the bottom of the mixing and drying zone MZ transfers material received from the upper conveyor 15 through a vertical transfer pipe 17 back into the drying tank 4 along with new material to be dried. A discharge screw conveyer 21 is connected to the drying zone DZ to discharge out dried material continuously.

Abstract: A waste carbonizing and energy utilizing system comprises a carbonizer, a gasifying fusion furnace, and a power generation plant for utilizing heat energy. The carbonizer 20 carbonizes waste to generate charcoal. The gasifying fusion furnace incinerates the charcoal, and then the heat generated by the incineration of the charcoal is used for operation of the power generation plant. Exhaust heat from the power generation plant is recycled to the carbonizer.

Abstract: A carbonizing apparatus permits effective use of an organic gas generated in a carbonizing vessel by utilizing an exhaust gas obtained by defusing the organic gas from the carbonizing vessel, as a heating source of the carbonizing vessel. The carbonizing apparatus has a carbonizing vessel having a carbonizing vessel jacket, into which a heating medium flows, a heat transmission surface forming an inner peripheral wall of the carbonizing vessel to be heated by the heating medium, a carbonizing object flowing means for flowing a carbonizing object charged thereinto, in contact with the heat transmission surface and a combustion furnace for burning an organic gas to be generated within the carbonizing vessel for defusing. The heating medium heating the heating surface is an exhaust gas as a heating gas after burning the organic gas in the combustion furnace, and the exhaust gas flowing into the carbonizing vessel jacket and discharging into an ambient air.

Abstract: Disclosed is an improvement in a drying apparatus comprising a cylindrical drying vessel, the inner wall surface of which makes up a heat-transmitting surface, a heat-generating means encircling the cylindrical drying vessel, and at least one rotating vane assembly rotatably fixed in the cylindrical drying vessel. The rotating vane assembly has vane sections, which leave between their circumferential edges and the heat-transmitting surface of the hollow cylinder an annular space small enough to allow wet material to cross and contact the heat-transmitting surface without falling therein. Each vane section extends obliquely upward in the direction which is opposite to the rotating direction, and the circumferential edge of each vane section extends less than 360 degrees as viewed from the top.

Abstract: A drying apparatus for removing moisture content from a substance to be dried, comprises a peripheral wall defining a working space for drying the substance, the peripheral wall defines at least an inlet for charging the substance to be dried, an outlet for taking the dried substance therefrom and a drain. A rotary spiral blade assembly is disposed within the working space and has a lower end, at which the substance accumulated on the bottom of the working space rides on a transporting surface of the rotary spiral blade assembly. The rotary spiral blade assembly is rotatable at a predetermined rotation speed sufficient for forcing the substance on the transporting surface to climb up toward the upper end of the rotary spiral blade assembly. The rotary spiral blade assembly defines a path for the substance reaching at upper end thereof to fall down to the bottom.

Abstract: Disclosed is a drying apparatus using a rotary spiral blade to put wet substance as bean-curd refuse into vigorous circulation in the vessel of the drying apparatus, thereby bringing the substance into contact with the heat conduction surface of the drying apparatus at an increased efficiency. The vessel has a steam jacket surrounding therearound for heating the inner wall of the vessel, thereby providing heat conduction surface thereon. The blade may be heated by steam, providing extra heat conduction surface.

Abstract: A watch dial is provided comprising a plastic or metal base plate. The base plate has thereon an uneven portion embodying a surface design, letter, window, symbol or mark. The uneven portion is formed by exposing photosensitive resin to ultraviolet light. The surface of the photosensitive resin portion of the base plate is metal-plated.

Abstract: A palladium-nickel alloy plating solutions formed from tetramminepalladous chloride is provided. The tetramminepalladous chloride is soluble in aqueous ammonia plating solution and is also water soluble. This permits replenishment of the palladium in a palladium-nickel plating solution during plating operation merely by adding the tetramminepalladous palladius chloride as a solid which is easily dissolved. The palladium-nickel alloy plating solutions contain between about 5 to 30 g/l of palladium and 5 to 30 g/l of nickel.
