摘要： An apparatus for use during continuous casting for the introduction of a metallic, typically steel melt into the casting head of a continuous casting mold, comprising a substantially tubular-shaped portion which directly merges with a pouring or casting vessel, the cross-sectional area of the tubular-shaped portion being greater than the cross-sectional area of the pouring outlet at the casting vessel. A chamber-like portion of larger cross-sectional area merges with the tubular-shaped portion. The chamber-like portion is equipped with a multiplicity of neighboring openings, the individual cross-sectional area of which is considerably smaller than the cross-sectional area of the tubular-shaped portion.

摘要： An apparatus for controlling the cooling of a continuously cast strand departing from a continuous casting mold of a continuous casting installation, comprising computer means, a cooling device forming a total cooling zone for cooling of the continuously cast strand, said cooling device being divided into sections, and said cooling device being further subdivided into sub-groups. Cooling agent delivery means deliver cooling agent to the cooling device, and means cooperate with the cooling device sections for applying such cooling agent to the strand. There are also provided means for controlling the quantity of cooling agent delivered to the cooling device sections and sub-groups, said controlling means incorporating a respective regulator means connected to said cooling device sections and said sub-groups for regulating the quantity of cooling agent supplied to said sections and sub-groups to maintain constant the residence time of the cast strand in the total cooling zone, said respective regulator means further being directly connected to and controlled by said computer means.

摘要： The invention relates to an environment-protecting method for the liming of raw hides, wherein, after an optional mechanical degreasing step, the hides are subjected to presoaking, chemical degreasing, washing, alkaline swelling and collapsing, enzymatic unhairing, plucking and liming, and the sulfide ions remaining in the liquor after liming are deactivated. According to the invention the raw hides are treated, prior to liming, with 0.05 to 0.50% by weight of a proteolytic enzyme with an Anson-activity of 1.2 to 1.5 in a bath of a temperature not exceeding 35.degree. C. and a pH value not exceeding 12, thereafter the hides are subjected to hair-destruction liming with a lime liquor containing not more than 2.0% by weight of disodium sulfide and/or sodium hydrogen sulfide, calculated for the weight of the raw hide, and the sulfide ions remaining in the lime liquor are oxidized directly in the liming vessel so that 100% by weight of water and at least 0.04% by weight of manganese sulfate are added to the used lime liquor in the presence of the limed hides, the hides are rotated in the liquor for at least 15 minutes, thereafter up to 1.0% by weight of technical hydrogen peroxide are added, preferably in three portions at intervals of 10 minutes, to the liquor within an additional rotation period not exceeding 150 minutes.
摘要翻译： PCT No.PCT / HU82 / 00009 Sec。 371日期1872年10月29日 102（e）日期1982年10月29日PCT提交1982年3月10日PCT公布。出版物WO82 / 03228 日本1982年9月30日。本发明涉及一种用于生皮的灰化的环境保护方法，其中在任选的机械脱脂步骤之后，将皮革进行预浸，化学脱脂，洗涤，碱性溶胀和塌陷，酶脱毛，拔毛和石灰，并且残留在液体中的硫化物离子在钝化后停用。根据本发明，生皮在石灰化之前，在不超过35℃的浴中具有0.05至0.50重量％的蛋白水解酶，Anson活性为1.2至1.5，pH值为不超过12个，然后用含有不超过2.0重量％的硫化二钠和/或硫化氢钠的石灰液进行毛发破坏，计算出生皮的重量，剩余的硫离子石灰液中的石灰液直接在石灰容器中氧化，使得在有灰皮的存在下，将100重量％的水和至少0.04重量％的硫酸锰加入到所使用的石灰液中，将皮革在将液体至少15分钟，然后在不超过150分钟的额外旋转周期内将至多1.0重量％的工艺过氧化氢，优选以10分钟的间隔三次添加至液体。
