1. Generation of motion forms with cycloids, epi- and hypocycloids
2. Cycloid gearing
3. Excitation of oscillations
4. Linear guideways with a cycloid cross section
5. Torque transmission in a coupling with a shaft of cycloidal cross-section
6. Application in rotary pumps, combustion engines
7. Crushing and grinding of substances

Application patterns of geometrical effects and forms:

1. Transition: EFFECT -> BI-EFFECT, e.g. helix -> double helix
2. Combination of two distinct effects or forms: EFFECT 1 + EFFECT 2
3. Combination of EFFECT with MOTION FORM
4. Combination of geometrical FORM with a FILLING SUBSTANCE
5. Combination of geometrical Effects or form (with or w/o filler) with physical or chemical effect
