Abstract: This invention provides a means to distribute any fluid-based substance (repellent) in a 360-degree pattern, over a large diameter coverage area, intended to dissuade wildlife, namely deer, from destroying plants, trees, flowers or the like. The invention is a self-sufficient unit which can be placed anywhere without the dependence on electric outlets, running water or solar clearance for purposes of electricity. This invention has a built-in programmable timer which can be set to activate and deactivate the unit for any duration of time while maintaining a weekly schedule and enabling the user to specify the routine that suits them the best. The device dispenses the repellent as often as the user desires per the programmable digital timer in order to protect the plant life within that zone. This unit is discreetly designed with multiple interlocking tubular sections that provide for adjustment in order to reach the height of operation that best suits the items the user wishes to protect from said wildlife.

Abstract: In a magnetically borne position-stabilizable flywheel, the force generation systems (at least for the radial drive) are designed in accordance with the electrodynamic principle and disposed in the interior of the wheel hub. The coils are situated on the stator and the associated permanent magnets on the rotor. Undesired oscillations are effectively damped. As a result of the displacement of the drive into the wheel hub, it is possible to use small coils. The swivel range of the wheel is sufficiently large.

Abstract: A stepping motor for rotating a body through small angles of rotation, the stepping motor having a stator and a rotor, an actively moveable connection unit for selectively connecting each of the stator and rotor to the body, and a drive which can be triggered and acts on the rotor. For performing an individual rotational step, the triggering of the drive and the connecting of the rotor with the body are essentially effected during a given period of time, and each time after performing a rotational step, triggering of the connection of the stator with the body takes place in order to maintain the body in the particular position attained.
