The Geneva drive or Maltese cross is a mechanism that translates a continuous rotation into an intermittent rotary motion. It is an intermittent gear where the drive wheel has a pin that reaches into a slot of the driven wheel and thereby advances it by one step. The drive wheel also has a raised circular blocking disc that locks the driven wheel in position between steps.

Moloch, Molech, Molekh, Molek, or Moloc, representing Semitic מולך m-l-k, (a root which occurs in various Hebrew and Arabic words related to kings) is either the name of a god or the name of a particular kind of sacrifice associated with fire. Moloch was historically affiliated with cultures throughout the Middle East, including the Ammonite, Hebrew, Canaanite, Phoenician and related cultures in North Africa and the Levant.
In modern English usage, "Moloch" can refer derivatively to any person or thing which demands or requires costly sacrifices.
