The invention relates to a convertible top for a convertible, comprising a front shell piece, a middle shell piece and a rear shell piece; the shell pieces, when in the closed state, being arranged as a roof over a passenger compartment of the convertible; the front shell piece being capable to be raised during a positively controlled opening operation such that it is moved over the middle shell piece; the rear shell piece being capable to be rotated into a folded-over position; the three shell pieces being designed such that they can jointly pivot counter to a direction of travel about a main bearing into a packaging position; wherein in the packaging position the front shell piece and the middle shell piece are oriented in the same direction over the rear shell piece, that is stored in the folded-over position. The invention further relates to a driving device for a convertible top, comprising a main bearing, a first link, a second link, an intermediate link, the intermediate link being coupled to the second link for activation purposes, a four-bar linkage, the four-bar linkage being coupled to the first link for activation purposes, a first bearing point, a driving cylinder, the driving cylinder being coupled with the main bearing at the first bearing point, and a push and pull rod, the push and pull rod being driven by the driving cylinder and being designed for a simultaneous action of force on the intermediate link and the four-bar linkage.

A jog dial actuating device and an electronic device are described.

An actuating drive for a rotor blade in a wind power installation is provided with an electric motor and a frequency converter which has a rectifier that is to be fed from a power supply system, a link connected to the rectifier, and a d.c.-to-a.c. inverter for feeding the motor, the link carrying a specified nominal operating voltage in a network-fed normal operation of the frequency converter. Furthermore, an auxiliary energy supply device is provided that is connected to the link. The auxiliary energy supply device includes and energy store which makes available a support voltage that amounts to less than 80% of the nominal operating voltage of the link. A diode is connected between the energy store and the link, and is arranged, with regard to its forward direction, in such a way that it feeds a support voltage from the energy store into the link if the link voltage falls below the support voltage. The diode prevents a current flow between the energy store and the link if the link voltage is greater than the support voltage. A charging device for the energy store has a lower charging voltage than the nominal operating voltage of the link.

A belt having a first cover layer with a first top surface and preferably also a second cover layer with a second top surface, wherein the first cover layer and, if present, the second cover layer are made of a foam having a thermoplastic or thermoplastic elastomer, in particular a TPU or PEBA. The belt is suitable e.g. as a machine tape in mail sorting machines and for power transmission.

A drive force output apparatus has a controller that sets an upper limit of power allowed to be consumed by an auxiliary based on at least a reference power storage amount corresponding to the reference of the range in which the power storage amount of a power storage is monitored and controls a power generator, an electric motor, and the auxiliary such that drive force corresponding to target drive force is output to a drive shaft while the power consumed by the auxiliary remains equal to or smaller than the upper limit.
