1. Dosers and filters, e.g. through gap adjustment between the turns of a tape helix
2. Telescopic tape helix as a movable safety coating
3. Accumulation of mechanical energy in a helix or spiral spring.
4. Gripper and clamping devices
5. Transformation of rotary motion into linear motion e.g. with cam or helix mechanisms

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
