    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: 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.
