An adjustment mechanism for a vibratory mechanism of a surface compaction machine, the adjustment mechanism includes a torque limiter coupled between the first eccentric shaft and the second eccentric shaft that prevents relative rotation between the shafts and a phase adjustment between the shafts when a net torque applied to the torque limiter is less than a locking torque threshold. Application of a net torque to the torque limiter that is greater than or equal to the locking torque threshold causes the first eccentric shaft to rotate with respect to the second eccentric shaft. An actuator subassembly selectively applies a linear force cause a first torque to be applied the first eccentric shaft sufficient to apply a net torque to the torque limiter that is greater than or equal to the locking torque threshold to cause the first eccentric shaft to rotate with respect to the second eccentric shaft.

The invention relates to a tamper device for a screed of a working machine, in particular a paver. The device comprises a rotatable driveable tamper shaft with an eccentric section, an 5 eccentric bushing mounted on the eccentric section, and a connecting rod rotatable mounted on the eccentric bushing for being driveable with stroke motions having a stroke, the stroke being adjustable by an rotational adjustment of a relative rotational positioning between the eccentric bushing and the eccentric section. The device further comprises an inner-toothed hollow 10 wheel gear train for providing the rotational adjustment. The gear train is connected to the tamper shaft, to the eccentric bushing, and to a drive force receiving element configured to be able to receive a drive force for driving the innertoothed hollow wheel gear train when the tamper shaft is rotating.

An apparatus that generates vibrational motion is disclosed. The apparatus includes a first mass, a second mass, a drive system, and a control system. The first mass is eccentrically mounted on, and configured to rotate about, a first shaft. The second mass is eccentrically mounted on, and configured to rotate about, a second shaft, with first and second shafts sharing a common axis. The drive system imparts rotational motion to first and second shafts, and the control system controls rotational frequencies, directions, and initial angles of the first and second masses. Linear, elliptical, or circular vibratory motion of the apparatus may be induced by controlling such rotational properties of the first and second masses. The apparatus may include a measurement device that measures angular position and/or velocity of the first and second masses. The control system may control the vibrational motion based on measurements taken by the measurement device.

The group of inventions relates to the field of medical technology, particularly to massage devices for personal use. The essence of the invention is a massage device capable of simultaneously stimulating two regions of the body, particularly through reciprocating sliding and reciprocating gyratory sliding along a span of movement comparable to the length of a vagina. This aim is achieved by a device comprising a first element, a second element, and a stimulating element comprising an electric means of acting upon the body of a user. The first element comprises a first surface section, and the second element is elongated and connected by its ends to the first element and to the stimulating element, which comprises a second surface section. The second element is bent and is capable of being elastically straightened and of moving the stimulating element from a first position.
