    Abstract: A brake for a rotatable shaft in which the shaft is joined or is integral to one of a concentric pair of members consisting of an inner and outer members having an annular gap therebetween in which an O-ring is disposed of such a size as to make an interference fit with both members and therefore is radially compressed and deformed in the gap to provide a high static braking torque. One of the members is axially moveable between limiting axial positions, such movement causing a rolling of the O-ring along the gap. A recess is formed in the outer member for interrupting the annular gap and providing free accomodation of the O-ring in one position of axial relationship of the members to permit relative rotation therebetween.

    Abstract: An irradiation method and apparatus in which an electron beam is diverted along a path which is caused to rotate about the beam axis and to intersect and sweep about a cone directed through the target to be irradiated and to thereby enter the target at an oblique angle. Apparatus is disclosed for causing the beam to take a rotating helical path and for passing the target through the imaginary apex of the cone shaped irradiation pattern of said rotating beam. Other apparatus is disclosed for coaxial irradiation from within hollow tubular targets and is particularly adapted for the irradiation of plastic tubing at the time of extrusion.
