    摘要: A packer apparatus for the internal sealing of pipe leaks having a cylindrical structure and a single sleeve located on the exterior of the cylinder. The single sleeve has a pair of inflatable chambers connected together in spaced relationship to each other and air hoses connect through the cylinder to each of the inflatable chambers for inflating and deflating the chambers remotely with air pressure. Chemical lines are connected through the cylinder and through the sleeve between the inflatable chambers. The cylindrical structure is made of two or more segments and is collapsible for reducing the size of the packer. The single sleeve is made of rubber reinforced with tire chord and is held to the cylinder only by the connections with the chemical and air lines.

    摘要: A Freeman type electron bombardment ion source includes dual filament electrodes positioned in an arc chamber having a slit for extraction of an ion beam. The filament electrodes are symmetrically positioned with respect to the extraction slit. The filament electrode currents are equal in magnitude and oppositely directed. As a result, lateral magnetic fields in the region of the extraction slit are substantially eliminated.
