    摘要： The invention relates to the re-utilization of cement slurry previously regarded as waste. The method involves separating water from the slurry so as to concentrate it, agitating the concentrated slurry so as to keep it in uniform disperson and disposing of the concentrate by mixing it in controlled proportion with fresh concrete. Apparatus is described which concentrates cement slurry and stores it as a suspension of suitably uniform density for disposal in the above manner.

    摘要： A rotary driven conical drum into a large end of which sludge and a flocculating polymer are discharged, constitutes a contact chamber, and is equipped with baffles and weirs. The polymer is supplied to a large end of the drum and mixing is accomplished in the large end of the drum where the surface area of the drum is moving most rapidly. Thereafter the mixing action is slowed down by travel of the mixture to the smaller end of the drum, where the surface area of the drum is moving more slowly, to build up the flocs. The sludge/polymer mixture produced in the contact drum is then discharged through a conduit into the large end of a rotary driven conical concentrator drum. A maximum amount of the free water in the mixture is released from the concentrator drum through its screen side wall at the large end of said drum. The flocs remaining in the screen drum, after initial release of the water therefrom, are protected by their travel to the smaller end of the drum where the surface movement is slower. The resulting thickened or dewatered sludge is removed from the smaller end of the concentrator drum as a formed cake.

    摘要翻译： 将排出了污泥和絮凝聚合物的大端的旋转驱动锥形滚筒构成接触室，并配有挡板和堰。 将聚合物供应到滚筒的大端，并且在鼓的大端部中进行混合，其中滚筒的表面积最快地移动。 此后，通过将混合物移动到滚筒的较小端部，其中滚筒的表面积更慢地移动，以形成絮凝物，混合动作减慢。 然后在接触鼓中产生的污泥/聚合物混合物通过导管排放到旋转驱动锥形浓缩鼓的大端。 混合物中的游离水的最大量通过其在所述鼓的大端处的筛网侧壁从浓缩鼓中释放出来。 在初始释放水之后，筛网中残留的絮状物通过其行进保护到滚筒的较小的端部，其中表面运动较慢。 所得到的增稠或脱水的污泥作为成形的滤饼从浓缩鼓的较小的一端去除。

    摘要： Spool of tape and all necessary resin-forming reactant liquids are packaged in a "one-shot", disposable container for delivery to a physician who mounts the unopened package on an activator machine which spins it in successive operational stages to first activate the reactant liquids by mixing in a mixing region of the package and then wet the tape with the activated liquid by centrifuge, subsequent centrifuging removing excess liquid, whereupon the package is opened and the spool of tape, now damp with the curing resin thereon, is removed for winding on the patient's body to form a polyurethane resin orthopedic cast which hardens within minutes in air and without additional curing procedures. Preferred reactant liquids, plasticizers, and catalysts are disclosed, which have long shelf-life within the package. Package of materials includes special container having inner container containing one reactant liquid; means for opening inner container upon mounting package on activator machine to permit its contents to mix with other reactant liquid disposed at the bottom of the outer container; paddle members for mixing the reactants responsive to intermittent spinning of the package while in a tilted position; and an interior partition configured both to provide a funnel for channeling the polymerizing liquid into a hollow core of the tape spool, and to provide a peripherally extending excess liquid collection region surrounding and extending below the tape spool.

    摘要： A method and apparatus for mixing fine powdered materials without creating an objectionable dusty environment, which consists in placing an open-topped container on a scale, placing a hood over the open-topped container, and with the hood interior connected to a source of suction, successively pouring the materials to be mixed into the container through a hole in the top of the hood and proportioning the materials by means of the scale. With the container thus filled, its open-topped upper portion is inserted into the downwardly facing mouth of a tiltable mixing drum and secured thereto in such a manner that the container tightly closes the mouth of the mixing drum so that admixture of the drum contents during rotation of the drum can take place without dispersing dust or fine powder into the atmosphere.
