  • Patent number: 4471226
    Abstract: An improved safety housing for a radiation source used in polymerization of materials. The housing includes an interlock feature which prevents activation of the source unless the shield is placed upon the work piece. A spring loaded switch on the surface which abuts the work piece and a second magnetic switch are used to prevent accidental activation. The unit uses a mechanically interlocking locator plate which is aligned in advance of the insertion of the housing into it, and shields the operator from any stray radiation when in use.

  • Patent number: 4346599
    Abstract: Apparatus for ultrasonically testing polymer materials includes means for measuring the thickness of the specimen and for measuring the mass density of the specimen in situ. Ultrasonic measurements of the specimen are obtained. Then the specimen holder is rotated past the critical angle and new ultrasonic measurements are obtained. From these ultrasonic measurements the storage and loss moduli and attenuation coefficients for the polymer specimen are obtained.
