Regenerative braking for bicycle - has elastomer strip twisted to store energy by friction roller held against tyre

The braking system has two metal friction rollers (8,10) mounted in a housing with a pivot action to bring either one or none of the rollers into contact with the tyre (54). The rollers (8,10) are coupled together by meshing gears (12, 14) to drive the rollers in opposite directions. Through friction contact with the tyre one roller (say 10) twists the elastomer strip (44) to store energy while the other roller enables the energy to be returned to the wheel. The elastomer strip is twisted by a gearing linked to the rollers. A friction wedge (6) blocks the roller action when they are lifted off the tyre and allows the stored energy to be retained. The pivot action of the roller mounting is controlled by a Bowden cable or by a mechanical sensor (86) on the bicycle chain. ADVANTAGE - Compact braking system, improved handling of bicycle.

Store for wind energy has incoming wind energy transmitted via cam star to lifting lever connected by freewheel to transport shaft turning spring store.

The incoming wind energy is transmitted via the cam star to the lifting lever that is connected by a freewheel to the transport shaft. With a lifting movement, the transport shaft turns somewhat and turns the spring store. The transport shaft is prevented from turning back however by a second freewheel. The lifting lever can return into its home position and make a further rotary movement. The home position of the lifting lever however is prevented from release by a centrifugal force-controlled impact at low speed so that with minimal input power and speed, only a minimal lifting displacement is attained and thus with little input power, a minimal feed and storage is attained.

Motor driven by potential energy of springs - has driving mechanism within drum on shaft mounted eccentrically to produce net moment on shaft

A shaft (1) carries two discs (6, 7) spaced axially apart forming a drum between them. A rectangular force plate (11) is connected to pins (19) on one disc (7) by tension bands (25) and to a balance arm (21) on the shaft through roller pins (24). The pins have an elastic linkage (28, 39) to the disc (7). A similar force plate (12) is connected between the other disc (6) and the balance arm (21) in an identical way radially opposite the first plate. There are springs (36) between the shaft and plates (15, 16) which link the balance arm with the force plates. The pins are positioned on the discs so that the forces on them have a resultant moment about the shaft.

Spiral motor

A spiral motor is a device with steel bending sheet or steel bending strip specially formed for the purpose, which is bent and tensioned according to a corresponding spiral function r = f( phi ) and in which energy thereby produced is converted into an open system of forces and, acting with constantly resulting torque, causes a persistent rotation about the centre of rotation of the rotary disc of the spiral motor. A spiral motor has a long life, does not need any explosive and combustible fuels, as a result of which no environmental pollution is produced, either, and whilst operating it is quieter than electric motors. Its overall volume is approximately equal to that of a conventional motor of the same kilowatt power. It is suitable for motor vehicles of all types and in industry, the aviation industry for aircraft and in electricity generating stations for driving electric generators for generating current. There is therefore no need of this ballast with explosive and combustible fuels ...

An electrical generator for powering a radio comprises a spring motor (4) which is wound up by way of a key (18) such that the subsequent rotation of a torque drum (8) as a stressed spring (12) unwinds therefrom generates electrical power. The rotational speed of the drum (8) is geared up by gear means (14) and rotates the rotor of an electrical motor (16) to generate an output voltage. The output voltage is regulated by way of a Zener diode (24) and is fed to a radio by way of a jack plug. The simple wind up mechanism has been found to be able to power a radio for the order of one hour. The generator can also be used to charge batteries. ...

SPRING BARREL MODULE

The invention concerns a spring barrel module having two chambers. A spring is located in the first chamber and a damper in the second chamber. The unidirectional damper is implemented by a clutch means that connects the damper plate to the spring shaft when the tightened spring is released, whereby the rotation of the damper slows down. Correspondingly, the clutch loosens the connection between the damper plate and the spring shaft when the spring is tightened. In low temperatures (e.g. below 0 ~C degrees) the damper fails to dampen the rotation. The unidirectional feature of the damper improves both usability and durability. Breakage of the mechanical components of the spring barrel is prevented by an overload clutch, which means that the spring barrel module will tolerate even relatively rough handling of the equipment.
