    摘要: The system provides for the commutation of a brushless direct-current motor. A virtual star is provided that is analogous to the motor. The virtual star is formed of resistors. A comparison device continuously comparing the voltages of the two star center points of the motor star and the virtual star in all phases. The comparison results are used to generate a signal for controlling the commutation.

    摘要: A roller frame including at least two rollers mounted in a housing between which a nip can be formed. The ends of the rollers are supported in rotary fashion in bearings and at least one of the rollers is embodied as an advancing roller and has an adjusting system by which it is possible to move the bearings of the advancing roller, thus changing the nip. The adjusting system has a rack and a pinion whose teeth engage with those of the rack and can be driven to rotate by a motor. It is possible to change the distance between the pinion and the rack by changing the tooth engagement depth between them.

    摘要: A drawer configured to be extended from and retracted into a furniture body. The drawer includes a bottom part; a front panel; two lateral frames; and a back wall connected via a corner joint to an end region formed with one of the lateral frames. Each corner joint including a first connecting part and a second connecting part pivotably connected to the first connecting part. The second connecting part includes detent means for connecting the second connecting part to either the first connecting part or the back wall. The first connecting part is connected to an adapter associated with the end region formed by the back wall with one of the lateral frames.

    摘要: A method and a device for producing a film made of a thermoplastic material, wherein a plastic melt is blown up into a film bubble and is shaped into a desired film by a calibrating arrangement, and a downstream arranged flattening device. For providing as contactless as possible a guidance, calibration and flattening, film guidance elements are used with a laminar uniform air cushion between the film guidance element and the surface of the film bubble, without contact between the surface of the film bubble and the film guidance element.
