A method of joining metal and metal, or metal and ceramic parts, wherein a first metal part is selected and then processed to form a bond coat that will effectively bond to a sealing material which in turn bonds to a second metal or ceramic part without degrading under the operating conditions of electrochemical devices. Dosage forms which differ in shape or size are obtained in one step. Based upon sensed speed and sensed acceleration, the controller 48 calculates a filtered speed of an elevator mass such as an elevator car 16 or counterweight, and compares the filtered speed to the threshold speed to determine whether an over-speed condition has been reached. Further, the plastic shell is preferably supported on a fluidized bed during this process. The contact and resting surfaces each have corresponding structures that can engage each other such that the U-shaped inserts can each be fastened in a detachable manner to the center piece.
