Title: Repeater housing
Inventor: SULLIVAN MELVIN
IPC: H02G15/14
Filed: 1986-08-08
Abstract: An electrically-insulating liner tube (3) is inserted into a repeater housing (seacase) (2) with interference fit by a method involving the use of a vacuum applied to the inside of an oversize liner tube whereby to reduce the outside diameter thereof of a value at which it may simply be slid into the housing.

Title: Fusion reactor apparatus.
Inventor: STENBACKA CHRISTER
IPC: C03B37/14
Filed: 1989-07-28
Abstract: This invention relates to a nuclear fusion reactor, to a nuclear reactor having a plurality of adjacent reactor units, to a method of operating such a nuclear reactor, and to ion beam treatment apparatus for treating a target; in another aspect, the invention relates to a method of treating an optical fibre. A fusion reactor comprises a stack of units (10) each comprising a pair of annular, coaxially disposed magnets (12). The magnets (12) capture and store ion beams which are capable of being deflected rectilinearly through a target region located on a common axis at the centre of the annuli. The present invention provides a target mechanism (14) operative to dynamically pass the target material (16) through successive target regions. Each unit (10) is arranged to provide different particle beams such that pre- and post-reaction treatment of the target material may conveniently be undertaken as well as nuclear fusion itself. Similar apparatus is used for optical fibre implantation and other treatment, substituting the fibre for the target (14, 16).
