A gearing having a shaft that projects from the gear interior into the environment, the shaft being sealed with the aid of at least one contactless seal, and the opening of the contactless seal, which is oriented toward the interior of the gearing, i.e., the spatial region of the gearing that contains the lubricating oil, being disposed above the lubricating oil level that comes about when the gearing is not in operation, a tin piece being disposed between the opening and the gear-tooth piece situated closest to this opening and generating lubricating oil waves and/or lubricating oil foam from the lubricating oil bath.
The invention relates to an installation and method for operating said installation, comprising a drive device that can be connected to a supply voltage source, particularly an alternative voltage source, via electrical lines which are arranged in the installation by means of a device, particularly a control device. According to the invention, information can be transmitted between the control unit and the drive device using said lines.

An arrangement is disclosed that implements a different number of logical slaves in a field device for use in an AS interface network as a function of the assigned address. The slaves may be addressed using the assigned address in the standard or in the expanded addressing mode. In a field device, it is possible to provide slaves having different profiles, via which different data types may be exchanged. A method is described with which a field device having different slaves is able to be addressed in a simple manner while avoiding double addressing.
Disclosed is a consumer comprising means for inductively supplying the consumer with power. Said means encompass an insertable part which is supplied with power after being inserted into the consumer.
A spool including at least one bobbin and one winding wire, especially a winding wire lacquered for electrical insulation, the bobbin including at least one channel, especially one developed as a pocket, at least one sleeve being electrically connected to the winding wire, the sleeve being electrically connected to an electrical line, especially a stranded conductor of a cable, the sleeve including deformable regions, for producing the electrical connections, a respectively deformable region being deformable in such a way that a force--locking connection is provided and welding is able to be carried out.
