Note

In this subclass, the following term is used with the meaning indicated:

–

"motors" means mechanisms for producing mechanical power from potential energy of solid bodies.

Spring motors (spring-driven toys A 63 H; springs in general F 16 F; precision time mechanisms, e.g. for clocks or watches, G 04 B)

characterised by shape or material of spring, e.g. helical, spiral, coil

using rubber springs

Other parts or details

for winding

for producing output movement other than rotary, e.g. vibratory

Other motors, e.g. gravity or inertia motors

using wheels with circumferentially-arranged compartments co-operating with solid falling bodies (F 03 G 3/04 takes precedence)

driven by sand or like fluent solid material

using pendulums

using flywheels

Devices for producing mechanical power from geothermal energy [5]

with direct fluid contact [5]

with deep-well turbo-pump [5]

with fluid flashing [5]

Devices for producing mechanical power from muscle energy (driving cycles B 62 M)

of endless-walk type, e.g. treadmills

Horsemills or the like

other than of endless-walk type

for combined actuation by different limbs, e.g. hand and leg

Devices for producing mechanical power from solar energy (solar boilers F 24) [5]

using a single state working fluid [5]

gaseous [5]

with solar energy concentrating means [5]

Mechanical-power-producing mechanisms, not otherwise provided for or using energy sources not otherwise provided for

using pressure differences or thermal differences occurring in nature (F 03 G 7/06 takes precedence)

Ocean thermal energy conversion, i.e. OTEC [5]

using expansion or contraction of bodies due to heating, cooling, moistening, drying, or the like (using thermal expansion of non-vaporising liquids F 01 K)

recovering energy derived from swinging, rolling, pitching, or like movements, e.g. from the vibrations of a machine

Alleged perpetua mobilia (using hydrostatic thrust F 03 B 17/04)
