Abstract
An enclosure of the type having a plurality of members weldable to each other to enclose and hermetically seal a pulse generator. In the present invention, the members consist of first and second members or segments each having a continuous side wall with the side walls having generally circular termini of substantially equal diameter. When the sidewall termini are in abutting relation to each other, rotation of the members about the axes of the circular termini will present the entirety of the abutment to substantially the same location for sealing, as by welding, for example. One or both of the side walls may be provided with one or more recessed areas to facilitate electrical communication with the enclosed pulse generator, each recessed area being formed by a platform subtending a portion of the arc of the sidewall circular termini and a web extending between the platform and the subtended portion of the circular termini. The platform may lie entirely along a chord of the side wall circular termini or, alternatively, may include a first portion lying only partially along that chord with a second portion angularly disposed relative to a first portion and extending toward the sid…
