Abstract: An apparatus for producing a very high DC potential output from an AC input. Multiple secondary circuits, each comprised of an individual coil wound about a separate magnetic core, are positioned within the magnetic field of a single primary coil. The output of each secondary circuit is rectified. The output of all secondary circuits is combined in series to provide the high DC potential. The seconary cores are supplied in parallel from the magnetic flux of the primary coil. The primary core and coil form an essentially cylindrical shell, with the secondary cores and coils located within the cylinder interior.

Also provided is a field former controller to compensate for induced flux variations caused by an oscillating particle beam.

Abstract: Apparatus for conveying articles of length L through an irradiation beam of width B, where L substantially exceeds B. The articles are supported on carriers which are suspended between and more along two tracks positioned with the beam therebetween. The carriers travel for a first distance with the articles extending transversely relative to the two tracks to permit close-packing of the carriers as they move toward the beam. As each carrier approaches the beam, it is reoriented relative to the two tracks to increase the exposure angle defined between (a) the carrier dimension along which the article extends and (b) the width of the beam. After exiting from under the beam each carrier is preferably returned to a transverse travelling orientation relative to the two tracks. The invention further includes the directing of carriers along monorails enroute to and/or from the two tracks.

Abstract: The monomer content in acrylonitrile containing polymers, as for example bottles formed from acrylonitrile/styrene copolymer, is substantially reduced by applying ionizing radiation at conventional rates in low dosage levels.

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.

Abstract: Apparatus for guiding a cable travelling along a longitudinal path through a beam of radiation in a shielded chamber, the apparatus including rollers disposed about the cable in a manner which prevents the leakage of radiation via apertures in the chamber through which the cable enters and exits. Specifically, the apparatus includes sets of rollers spaced at longitudinal intervals along the cable, the rollers in each set being positioned at angular intervals about the longitudinal axis of the cable. An angular offsetting of rollers in different sets, so that a roller in one set is longitudinally aligned with the spacing between rollers in other sets, is provided. By selecting rollers of prescribed dimensions, by placing the rollers at prescribed angular intervals in each set, and by angularly offsetting a plurality of sets by prescribed angles, a plurality of sets of rollers--when placed proximate to the entrance or exit to an aperture--can preclude radiation leakage through the aperture.

Abstract: Method and apparatus for wide angle beam scanning to internally irradiate hollow objects with a beam of charged particles utilizes a scanning deflection device to scan the beam within the object to be irradiated through an angle of deflection greater than 90.degree. from the axis along which the beam is received by the scanning deflection device. The object to be irradiated can be rotated about the scanning deflection device or the scanning deflection device can be rotated to circumferentially irradiate the object, and the object is translated relative to the scanning deflection device to irradiate an entire object, such as a tube, a container having a closed end or an object having a toroidal configuration, such as a pneumatic tire.

Abstract: The voltage at the high voltage terminal of a first particle accelerator is stabilized particularly during pulsed operation by producing a compensating current at its accelerator terminal such as to maintain the voltage of the terminal constant. The compensating current is produced by a second particle accelerator coupled between the accelerator terminal and a high voltage terminal connected with a high voltage DC power supply. The charged particle flow through the second particle accelerator is such that the charge on the accelerator terminal of the first accelerator remains substantially constant even though the voltage at the high voltage terminal drops during simultaneous pulsed operation of both particle accelerators.

Abstract: A higher current capability is provided in a high voltage accelerator of the Dynamitron type (U.S. Pat. No. 2,875,394) by paralleling basic building blocks whereby increased current is achieved without any change in the circuits of the basic building block which are interleaved to permit parallel connection and thus current multiplication without affecting machine voltage or performance.

Abstract: A method of making a bond structure and a bond structure are provided that produce concurrently a peel bond and a lap bond. One end of a sheet to be joined to a second end of the same or other sheet is folded back on itself and on end of the other member inserted. The two pairs of contacting surfaces thus formed are subsequently bonded to each other. The bonding may be by any means and the clamping force across the bond during bonding need be applied from one side of the sheet only. By insuring that the peel bond fails before the material, a flat lap bond may be achieved by causing only the peel bond to fail.

Abstract: A scanning beam deflection system and method utilizes a beam scanning device for producing rays diverging from a central axis of a beam of charged particles and a deflection magnet assembly for deflecting the scanning beam substantially 270.degree. within an evacuated deflection chamber such that the deflected scanning beam exits an offset beam window in the deflection chamber and has rays diverging from the central axis of the deflected scanning beam at substantially the same angle as the diverging rays produced by the beam scanning device. The system and method is particularly useful for irradiating internal surfaces of hollow articles with the deflection chamber and deflection magnet assembly disposed along an axis of symmetry of the object.

Abstract: The monomer content in chlorinated hydrocarbon plastic materials, as for example articles made from polymers of chloroprene vinyl chloride and vinylidene chloride, is substantially reduced by applying ionizing radiation in low dosage levels, e.g. 0.05-2 megarad to the material, either to the fully formed article, or the pellets from which the articles are molded or to the ground resin powder from which the pellets are formed.
