An eccentric adjusting unit is disclosed, for example, for adjusting a connection point for a control arm of a wheel suspension. The unit may include an electric motor and an eccentric gear section. The eccentric gear section may have an input shaft and an output shaft, wherein the input shaft is configured to be driven by the electric motor and the output shaft rotates eccentrically with respect to an output axis of rotation and can be in operative connection with the connection point or forms this connection point. The eccentric gear section may have a star wheel gear stage.

A people conveyor (10) comprises: a chain of conveyance elements (12), which are configured for conveying people; a drive unit (14), which is configured for driving the chain of conveyance elements (12); and a self-locking gear (20; 40), which is configured to lock when no torque is transmitted from the drive unit (14) to the chain of conveyance elements (12).

A gearless transmission may provide a similar outcome to a gear train, without meshing teeth. Such a gearless transmission may comprise an input shaft comprising a plurality of lobes disposed thereon. The lobes may extend radially from the input shaft in opposite directions from one another. Each of the lobes may comprise a plurality of connecting rods freely rotatable thereabout. Each of the connecting rods may be slidably attached to a hollow body disposed around the input shaft. The hollow body may be formed from a plurality of rings fixed together and secured to an output shaft.

Combining rotating and gyrating structures, to achieve a specific velocity of a mass, within a device, can reduce the number of parts as compared to a design using only gyration induced acceleration, and can reduce the absolute dimensions compared to a design using only rotation induced acceleration. Synchronous motions allow the accelerated mass to transition from a rotating reference frame to a gyrating reference frame without a significant physical gap or jump, greatly reducing any potential for ricochet. Re-phasing within the device may be accomplished several times. The mass is ejected and directed toward a target.

A multiple-antenna positioning system with a single drive element, providing reduced weight and complexity over systems that have a drive element for each antenna. In certain examples, each antenna can be coupled with a rotating spindle, with each antenna spindle being coupled with a pair of link arms. By driving a single drive spindle, each of the antenna spindles in the system can be rotated by the associated pair of link arms. The link arms can have an adjustable length, such as through a turnbuckle mechanism, to reduce backlash in the system, and in some examples can apply a preload to the system. By reducing backlash, the multiple antenna positioning system can have improved responsiveness to a rotation of the single drive element, as well as improved stability of the positioning of each antenna when the drive element is held in a fixed position.

A device for power transmission includes a drive plate, a support plate, an output plate, a first main slide rail, a first drive train element, a first counterforce element, a first power transmission element, and a first output element, wherein the drive plate, support plate, and output plate are disposed above one another. The counterforce element generates a counterforce such that the total force from the driving force and the counterforce acting on the first main slide rail leads to a rotational movement of the support plate. The first power transmission element causes a rotational power transmission during rotational movement of the support plate and the first output element is connected to the output plate such that during the rotational movement of the support plate, an output power transmission connection exists from the moving part of the first main slide rail to the first output element.
