Abstract: A floor grinding machine includes a supporting frame, a grinding unit attached to the supporting frame, and a drive unit connected to the grinding unit. The grinding unit includes an upper housing, a lower housing rotatably arranged in relation to the upper housing, and a planetary drive system connected to the drive unit. The upper housing includes a first side wall. The lower housing includes a bottom plate and a second side wall. One or more grinding disks adapted for holding a tool are rotatably attached to the bottom plate. The planetary drive system is arranged to rotate the lower housing and the one or more grinding disks. The first side wall at least partly overlaps the second side wall. A gap is formed in a radial direction between the first side wall and the second side wall, and a sealing element is arranged in the gap.

Abstract: A new and improved self-oscillating amplifier system is presented, suitable for use in high fidelity audio applications. The self-oscillating amplifier system comprises a feedback path and a forward path including a pulse modulator, a switching power amplification stage and a demodulation filter. The forward path further includes a pair of parallel forward filters preceding the pulse modulators, a differentiating forward filter and an integrating forward filter. The differentiating forward filter is utilized for controlling a switching frequency of the system while the integrating forward filter is utilized for controlling the behavior of the amplifier system within an operating frequency band (e.g. audio band). The self-oscillating amplifier system exhibits improved performance in terms of open loop gain, reduced phase turn and improved robustness as compared to other previously known self-oscillating amplifier systems.

Abstract: A park lock having a cam that is movable along a movement axis to cause corresponding pivotable movement of a pawl relative to a dog ring. The park lock mechanism includes a first actuator assembly and a second actuator assembly. The first actuator assembly has a first output member on which the cam is slidably mounted. The second actuator assembly includes a detent mechanism, which is configured to resist movement of the cam relative to the first output member, and a biasing element that is configured to store energy. Operation of the detent mechanism to permit movement of the cam relative to the first output member employs the stored energy in the biasing element to translate the cam on the first output member.
