  • Patent number: 4334783
    Abstract: A mixing device is presented which is suitable for use in the uniform mixing of polymer substances or the uniform mixing of polymer substances with, for example, fillers. This mixing device is composed of one mixing nozzle or two or more mixing nozzles mounted in parallel, which mixing nozzle comprises an orifice portion and an upstream compression zone and/or a downstream diffusion zone. A ratio of the maximum opening cross-sectional area of the compression zone or the diffusion zone to the minimum opening cross-section area of the orifice portion is 10:1 or more.

  • Patent number: 4107979
    Abstract: Environmental stress cracking of a given material is measured by a method comprising the steps of deforming a test piece of said material for thereby producing stress therein, placing the deformed test piece in a test environment, externally applying thereto stress of a magnitude smaller than that of the stress already produced therein until the test piece fractures and clocking the time the test piece stands in said test environment before fracturing. Said measurement is performed by use of a device which comprises means for holding test pieces, loading means for applying stress to said test piece holding means and indicating the displacement of the test piece occurring at the time of its fracture and means for sensing the displacement.
