    摘要： A process is disclosed for producing non-woven flat objects which are reinforced by means of a reinforcing inlay, in which the reinforcing inlay is electrostatically charged, then coated with a thermoplastic binder in powder form, the excess powder removed, and the inlay joined with at least one layer of a fiber fleece. The electrostatic charge is preferably produced by frictional contact of the inlay with an electrically nonconductive material, the coating is preferably accomplished by conducting the charged inlay through a fluid bed of said powder, the removal of excess powder is preferably accomplished by blowing air through the coated inlay, and the joining of the inlay with the fiber fleece is preferably accomplished by heat and pressure.

    摘要： Disclosed is an improved thermoforming process wherein the amount of plastic film forced into a mold cavity is restricted so that only the proper amount required is introduced into the cavity. The restricting step may be achieved by (1) clamping the film at the open mouth of the cavity and then forcing film into the cavity or (2) heating only those portions of the film which are needed to properly fill the cavity or (3) heating the film uniformly and then selectively cooling those portions of the film which should not be introduced into the cavity. Novel clamping apparatus is also disclosed.

    摘要： A hot roll, for use in a xerographic, dry-release, hot roll fuser, is made by a method which adds iron-containing, magnetically permeable, particles to the elastomer as the elastomer is mixed. The particles may be pre-coated with a silane adhesive promoter. The mixed elastomer is then injected around a hollow, cylindrical aluminum core. As the elastomer sets up, in the mold, a magnetic field is applied such that the iron-containing particles migrate toward the metal core, and away from the exterior surface of the elastomer. This exterior surface will later be used to fuse xerographic toner. After the elastomer has set, its external surface is ground slightly, to produce a true circular-cylinder, but without exposing the underlying, more dense, layers of iron particle filler. As a result, the elastomer-to-core interface is mechanically strong, and yet the fusing property of the elastomer is not degraded by the presence of filler.

    摘要翻译： 用于静电复合干燥脱模热辊定影器的热辊是通过在弹性体混合时将含铁，可渗透的颗粒添加到弹性体中的方法制成的。 颗粒可以用硅烷粘合剂促进剂预涂覆。 然后将混合的弹性体注入中空的圆柱形铝芯上。 当弹性体成型时，在模具中施加磁场，使得含铁颗粒向金属芯移动并远离弹性体的外表面。 此外部表面稍后将用于固定静电印刷碳粉。 弹性体固定后，其外表面略微研磨，以产生真正的圆柱体，但不暴露下层的，更致密的铁颗粒填料层。 结果，弹性体与芯体之间的界面机械强度较高，而弹性体的熔融性不会因填料的存在而降低。

    摘要： Apparatus for extracting precious metals from their ores in which the ore is particulated and mixed with a binding agent to form a paste. The paste material is discharged into a rotary drum at an extruding station where it is pelletized by forcing it through a perforated sidewall of the drum. The pellets are discharged onto a conveyor belt and are transported to a spray station where they are wetted with a lixiviant solution. The lixiviant coated pellets are then dried by exposure to a heated air stream at a drying station as they are transported to an open air curing stockpile. The cured pellets are heaped in a pile and are then washed with a water spray to yield a pregnant solution of a precious metal salt.

    摘要： A method of manufacturing a composite material which comprises filaments enclosed in a matrix of a high temperature resistant thermoplastic polymer. The method entails impregnating the filament with a first high temperature resistant thermoplastic polymer in an amount sufficient only to lightly bind the fibres together. The bound fibres are then interposed between sheets of a second thermoplastic polymer and the whole structure subjected to heat and pressure for a time sufficient to ensure impregnation of said second thermoplastic polymer into said filaments and diffusion of the first thermoplastic polymer into the second thermoplastic polymer.
