Abstract: A system for continuously processing PTFE by irradiation and grinding includes a processing vessel having first and second horizontally adjacent agitators in first and second transversely adjacent vessel portions. The bottom of the vessel has a step between the portions whereat heated air is injected for agitating and grinding the PTFE.

Abstract: An apparatus and system is provided for utilizing an electron beam machine to selectively and alternatively irradiate materials with electrons of X-rays; the conversion between electron radiation and X-radiation being achieved by interposing a plate of low Z material such as aluminum between the beam and the material to be irradiated, the plate having its surface facing the electron beam covered with an X-ray generating or high Z material. The plate serves as a mechanical support for the high Z material, an electron capture body and to some extent as a heat sink. Materials to be irradiated are disposed in a cart and are conveyed under the beam with the plate being interposed whenever a material to receive X-rays passes thereunder; the carts being employed to readily permit multiple passes of the material to be treated with X-rays under the beam whereby heat build up in the X-ray generating target placed over each cart may be maintained at acceptable levels.
