Abstract
A cartridge cover having slotted bosses which are positioned so that both the bosses and their slots are aligned with the vectorial resultant lines representing the direction of change that takes place during thermal expansion of the cartridge. Each boss has a fitting which engages pins fixed into the base of the cartridge, thereby securing the cover to the base. The cover and the base have different coefficients of thermal expansion. The slots are of sufficient length to allow all motion of the pins, taking place as a result of thermal expansion, to occur within the slots.
