Abstract: A housing for an electric machine includes a substantially cup-shaped outer housing having a first base portion and a first tubular portion adjoining the base portion. An inner housing, which has a substantially cup-shaped form, is arranged in the outer housing and has a second base portion and a second tubular portion adjoining the base portion. A cover is connected or connectable to the outer housing and/or the inner housing. At least one cooling channel is formed between the first tubular portion and the second tubular portion. A pocket is formed in the first base portion and forms a first cavity together with the second base portion, and a second cavity is formed in the cover. The first cavity is fluidically connected to the cooling channel via a first bore and the second cavity is fluidically connected to the cooling channel via a second bore.

Abstract: A clutch assembly with a rotatable clutch hub which is connected rotationally fixedly to several inner plates which may be brought into friction connection with outer plates of an associated clutch basket and form a plate pack. The clutch hub has at least one bore which allows a throughflow of a fluid from the interior of the clutch to the plates, and an oil conduction device attached to the clutch hub at the at least one bore.

Abstract: The invention relates to a processing device (1) and a method of controlling several processing tools (3, 4) of a processing device (1) for processing the material of workpieces (2). The workpiece (2) can be processed by a first processing tool (3), which is generated by a first radiation source (9), in particular a laser source, in the form of a processing beam (8a), and by means of at least one other processing tool (4) of a different nature or different origin, in particular a different radiation source (10), from the first processing tool (3), whereby the different processing tools (3, 4) can be placed in contact with a workpiece (2) in order to process the material, and processing of a workpiece (2) can be performed by only one of the processing tools (3; 4) at any one time.

Abstract: A method of forming an image in a surface by a laser mounted for orthogonal movement parallel to the surface by correlating the time lag between energizing and discharging the laser to a profile of the velocity at which the laser is moved relative to the surface. The image may be formed by writing or engraving.
