    摘要： An apparatus and a method for generating seismic waves utilizes a heavy flywheel positioned for rotation in a vertical plane to generate and store energy which is then transferred to the ground. The device includes two balanced hammers mounted on the flywheel as impact members. In operation, the flywheel is spun to a predetermined speed and then, on command, the hammers are extended outward from the flywheel so that one hammer strikes either a vertical or a horizontal strike member, thus providing a rapid transfer of a large amount of kinetic energy to the ground resulting in the generation of a set of seismic waves.

    摘要： A nozzle or tube which is useful for pouring molten metal, especially aluminum killed molten steel. The nozzle is formed from a blend of doloma and graphite which is bonded together in a carbonized matrix. Nozzles or tubes made in accordance with this invention have enhanced thermal shock resistance. Furthermore, the nozzles or tubes of this invention resist the formation of aluminum oxide therein when they are used for pouring molten aluminum killed steel. Consequently, these tubes or nozzles can be used in a continuous casting process for a long period of time without having to periodically stop the procedure and change the tubes as they become blocked with aluminum oxide. As a result of the thermal shock resistance, the usual preheating step prior to contacting the nozzle with the molten metal is greatly reduced.

    摘要翻译： 一种用于浇注熔融金属，特别是铝处理的钢水的喷嘴或管子。 喷嘴由在碳化基质中结合在一起的白云石和石墨的共混物形成。 根据本发明制造的喷嘴或管具有增强的耐热冲击性。 此外，当本发明的喷嘴或管子用于浇注熔融铝杀死的钢时，本发明的喷嘴或管子可以防止其中形成氧化铝。 因此，这些管或喷嘴可以在连续铸造过程中长时间使用，而不必周期性地停止该过程并且当它们被氧化铝堵塞时改变管。 作为耐热冲击性的结果，在喷嘴与熔融金属接触之前的通常的预热步骤大大降低。

    摘要： An apparatus and method for soil remediation replaces specific ions in the soil electrochemically, using a DC voltage source and special multicompartment anodes and cathodes, each comprising an inner compartment containing electrolyte and a submerged electrode, a salt bridge connecting the electrolyte to an outer compartment containing a specific solution with replacement ions for soil remediation, and a membrane holding in the replacement solution. The membrane is put into contact with the soil, allowing electrical contact and ion migration while keeping the solution inside the anode or cathode. The multicompartment structure prevents the hydroxide and hydronium ion emplacement that causes acid and base fronts to form.
