Abstract: An adjustable mounting assembly includes (i) a housing with front and rear collars joined by a threaded engagement, the rear collar including teeth oriented toward the front collar, (ii) a front body part extending outwardly through an opening in the front collar, (iii) an intermediate body part coupled to the front body part, and (iv) a rear body part coupled to the intermediate body part, the rear body part including teeth oriented toward the rear collar, the mounting assembly adjustable such that (a) when the threaded engagement is tightened, the teeth of the rear body part are positioned in an interlocking engagement with the teeth of the rear collar, preventing rotation about a pitch axis of the mounting assembly, and (b) when the threaded engagement is loosened, the teeth of the rear body part are disengageable from the teeth of the rear collar, allowing rotation about the pitch axis.

Abstract: A primary lithium cell having a wound electrode assembly. The electrode assembly comprises an anode comprising lithium, a cathode comprising a manganese dioxide and an electrolyte permeable separator therebetween. The electrode assembly comprises a cathode sheet, an anode sheet and electrolyte permeable separator sheet therebetween. The sheets are wound into a spiral roll. An exposed edge of each revolution of the separator sheet is then heat treated, for example, by applying a heated platen thereto to mold said exposed edge into a continuous separator membrane. The continuous separator membrane, so formed, covers and seals off said edge of adjacent revolutions of the cathode sheet and thus provides electrical insulation therefor. The electrode assembly can then be inserted into the cell casing so that the continuous separator membrane abuts a surface of the casing and provides electrical insulation between the casing and the wound cathode sheet.
