Title: Tundish
Inventor: NARUSE NORIYOSHI
IPC: B22D11/10
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To prevent the entrapment of slag and inclusion by the occurrence of voltex flow. SOLUTION: In this tundish 1, when the molten steel M charged by starting the casting is supplied into a mold from an immersion nozzle 9 through a flowing outlet 6, the molten steel M detours a baffer plate 11 and flows out from the flowing outlet 6 through the interval of supporting legs 12. In this way, in the molten steel M above the baffer plate 11, the molten steel surface is lowered in the almost horizontal state without causing any voltex flow. Therefore, while the surface of the molten steel M is lowered and reached to the upper surface of the baffer plate 11, the entrapment of the slag and the inclusion S caused on the surface of the molten steel M can be prevented.

Abstract: PURPOSE:To permit the cooling for a car interior independent from an engine and batteries by separating the absorbing liquid which absorbs the coolant evaporated in an evaporator into the absorbing liquid and the coolant and allowing the both liquid and water for cooling to circulate by a pump driven by solar batteries. CONSTITUTION:When liquefied coolant is sent into an evaporator 1 from a condenser 4 by a pump 6, coolant is jetted-out in mist form from a plurality of nozzles 1a, and the coolant robs heat from the air on the periphery and is evaporated. When absorbing liquid is sent into an absorbing device 2 from a radiator 5 by a pump 7, said absorbing liquid is jetted-out from a plurality of nozzles 2a, and the evaporated coolant is absorbed into the absorbing liquid. Since the cooled air on the periphery of the evaporator 1 circulates in a car interior, when a fan 8 is driven, the car interior is cooled. The absorbing liquid which absorbs coolant is sent into a regenerator 3, where the absorbing liquid and the coolant are separated, and the coolant is sent in gaseous state into the condenser 4, and the absorbing liquid is sent into the radiator 5. Since the pumps 6, 7, and 13 and the fans 8 and 9 are driven by solar batteries 10, use of an engine and batteries can be obviated.

Abstract: PROBLEM TO BE SOLVED: To provide a hardening composition to process hydrophilic colloid, for example, gelatin to be used to manufacture a photographic element by containing a vinyl sulfone hardener and sulfate of a quantity sufficient to restrain independent polymerization of this hardener. SOLUTION: A vinyl sulfone hardener and sulfate of a quantity sufficient to restrain independent polymerization of this hardener are contained. That is, the sulfate is an effective conductivity marker, and is an effective restrainer of independent polymerization in a vinyl sulfone hardening composition. An ammonium sulfate, an alkalin metal sulfate and an alkaline earth metal sulfate are contained in the sulfate useful for this purpose, but above all, use of the alkaline metal sulfate is preferable, and use of a sodium sulfate is particularly preferable. The vinyl sulfone hardener restrains independent polymerization by putting the hardener and the sulfate of a independent polymerization restraining quantity together without hindering their usability as the hardener, that is, a hydrophilic colloid cross-linking agent.
