A work machine enabling a hybrid drive system to be directly driven by energy contained in a return fluid discharged from a hydraulic actuator. The work machine includes a hydraulic actuator control circuit and a swing control circuit. The hydraulic actuator control circuit serves to control hydraulic fluid supplied from pumps of a hybrid drive system to travel motors and work actuators. The swing control circuit serves to control a swing motor generator, which functions as an electric motor and...

A stretching machine includes a bench having at least one base members. A cam is coupled to the base member or one of the base members, if there is more than one. A stretching arm is coupled to the cam at one end and has an extremity attachment device at its other end. An actuator is coupled to at least one of the base members and is coupled to the cam. The actuator enables movement of the cam and the movement of the cam enables movement of the stretching arm. There is a control mechanism for co...

A comminution machine for waste includes a rotor that carries blade elements and cooperates with counter-blades, which are fixed to the housing. The rotor is driven by a synchronous motor that is excited by a controllable frequency converter. In order to keep the connected power of the comminution machine small and nevertheless be able to apply a large torque to the rotor, the synchronous motor acts upon the rotor via a reduction gearing and a clutch.

A dishwashing machine is provided with a washing compartment and with devices for washing dishes using a washing solution as well as with a sorption drying device, which is connected to the washing compartment in an air-conducting manner via an outlet of the washing compartment and via an inlet of the washing compartment and which comprises a sorption column containing reversibly dehydratable material, the outlet of the washing compartment being connected to the sorption drying device via an air...
