Abstract: TREATMENT OF SINTERED POLYTETRAFLUOROETHYLENE WITH IRRADIATION AND HEAT TO PRODUCE A GRINDABLE MATERIAL Sintered polytetrafluoroethylene is nondestructively degraded so as to be grindable to a powder of an average size of less than 10 microns by a combination of irradiation by electrons or other subatomic. particles in the presence of oxygen or air and concurrent or subsequent heating at temperatures below the melting point of the material. The preferred effective and economic range of irradiation, heat and time at temperature is approximately 50-150 Mrads, 150.degree.F to 600.degree.F for at least about one-half hour depending upon desired average particle size and melt flow characteristics and acceptable yields of fine powders.

Abstract: PROCEDIMIENTO PARA ENCERRAR HERMETICAMENTE UN ARTICULO DENTRO DE UNA CUBIERTA DE POLIETILENO Y COPOLIMERO DE ISOBUTILENO. CONSISTE EN FORMAR UNA PELICULA DE POLIETILENO RETICULBALBE, QUE LLEVA UN COPOLIMERO DE ISOBUTILENO PARA LOGRAR QUE LA PELICULA SEA SOLDABLE TERMICAMENTE, LA CUAL ES IRRADIADA PARA RETICULAR EL POLIETILENO. LUEGO LA PELICULA SE CALIENTA POR ENCIMA DE SU PUNTO DE REBLANDECIMIENTO CRISTALINO, SE ESTIRA, ENFRIA Y SE ENVUELVE EL ARTICULO CON ELLA, SOLDANDO TERMICAMENTE LAS COSTURAS Y CALENTANDO POR ENCIMA DEL PUNTO DE REBLANDECIMIENTO CRISTALINO PARA LOGRAR UNA RETRACCION DE LA PELICULA.

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.
