Abstract: Acrylonitrile polymers, partic. including acrylonitrile/styrene copolymers, are exposed to ionising radiation at a dosage level of 0.05-2 megarads. Such polymers can be in the form of shaped articles. Irradiation can be followed by an HCN degassing treatment. The ionisation radiation can be provided by an electron beam. Other suitable copolymers are those of acrylonitrile with butadiene, methyl acrylate and other acrylates. If desired, the treatment can be applied first to the material in ground or pelletised form, then to the article produced from it. The material can also be treated in soln. or in suspension e.g. in a polymerisation medium. Carcinogenic acrylonitrile monomer can be removed while causing only a low level of HCN generation, which itself is removed in the process by degassing.

Abstract: CLOSURE METHOD AND APPARATUS 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 and 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 by 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 high voltage solid-state rectifier includes multiple series connected ac-compensated diodes and series buffer resistors in a stepped spiral stack. The stack is encased in a sectionalized faraday shield which provides 360 DEG isolation from external rf electrostatic fields and provides external capacitance grading along the stack. Spark gaps between shield sections prevent excessive voltage build-up due to electrical discharges and are arranged in line of sight of each other to permit the ultra-violet light produced from one spark gap firing to stimulate the firing of the other spark gaps. A trigger spark-gap derives its voltage from an inductance in series with the solid-state rectifier. Any electrical discharges which result in an excessive voltage appear initially across the inductance, firing the trigger spark gap which in turn initiates the other spark gaps to fire by ultra-violet stimulation.
