摘要： An improved pantograph apparatus for the duplication of original works of a large range of sizes, having a modular copying assembly mounted on two spaced support shafts and supported on each shaft at a desired height by upper and lower resilient compression members. The modular copying assembly is interchangeable with other modular copying assemblies to give the inventive apparatus great flexibility in the number of copies reproduced from one original. The resilient compression members are also interchangeable with other resilient compression members of different lengths for placing the copying apparatus at a selected height on the support shafts, which height may correspond to the maximum cross section of the original work being copied.
摘要翻译： 一种用于复制大范围尺寸的原始作品的改进的缩放仪装置，其具有安装在两个间隔开的支撑轴上的模块化复制组件，并且通过上下弹性压缩构件以期望的高度支撑在每个轴上。 模块化复印组件可与其他模块化复印组件互换，以使本发明设备在从一个原件再现的副本数量方面具有很大的灵活性。 弹性压缩构件也可以与不同长度的其它弹性压缩构件互换，用于将复制装置放置在支撑轴上的选定高度处，该高度可对应于被复制的原始作业的最大横截面。

摘要： A membrane process for producing a juice product with improved quality comprising feeding a single strength juice to a plurality of microfiltration/ultrafiltration stages wherein the first stage is a microfilter having a membrane pore size smaller than the spoilage microorganisms but substantially larger than the flavor and aroma molecules and wherein subsequent stages are ultrafilters having membranes of decreasing pore size.

摘要： The invention is a membrane separation device having a housing which serves the dual role of a lightweight, impact-resistant shipping container and a recloseable vessel for the separation membranes. The housing reduces handling of the membranes, facilitates assembly of permeation systems and improves repair, replacement and inspection of membranes. The housing is preferably fabricated from expanded polystyrene. In an alternate embodiment, the configuration of the inside surface of the housing may be altered to provide a non-uniform or non-cylindrical annular space. The separation systems are particularly useful for gas separations.
摘要翻译： 本发明是一种膜分离装置，其具有壳体，其用于轻质，耐冲击运输容器和用于分离膜的可再封闭容器的双重作用。 外壳减少膜的处理，便于组装渗透系统，并改进膜的修复，更换和检查。 外壳优选由发泡聚苯乙烯制成。 在替代实施例中，壳体的内表面的构造可以改变以提供不均匀或非圆柱形的环形空间。 分离系统特别适用于气体分离。

摘要： A membrane process for producing an improved product quality comprising feeding a clarified serum at an elevated pressure to a plurality of reverse osmosis units in two stages--the first having high-rejection polyamide membranes and the second having low-rejection membranes, wherein the permeate from the low-rejection membranes is recycled to the high-rejection feed.
