The brake cylinder has an annular supporting section with compressed-air union and onto which a pot-shaped cylinder section of thin sheet-metal fits. The two are secured together by a bayonet coupling, with lugs evenly spaced round the periphery, cut out from the sheet-metal of the cylinder and bent inwards. These bear against mating faces formed on the supporting section. The lugs of the cylinder...

The gear box is for motor vehicles, and has a selector shaft. The shaft carries the selector sleeve, which is axially displaceable between the change gears by gearshift forks. Auxiliary shafts carry one or more non-changeable gears. The dry space of the gear box part (3) contains electromagnetically actuated spring-tensioned friction clutches (6.1-6.12), to start and interrupt the power flux betwe...

Owing to the increasing range of functions of the components (28, 32), connecting and control devices can be exposed to damaging thermal loads. In the present device the power component (28) with the high power losses of the components (28, 32) is separated from a printed circuit board (31) which carries only signal processing components (32) and fitted on an inner side (24) of an outer wall (25) ...

In the case of an electric razor apparatus having a vibrating-armature drive, an air gap is located between the vibrating armature and an energising magnet which has a laminate stack. The razor apparatus has a dimensionally stiff carrier element (1) which has a bearing element for the vibrating armature on its end facing this vibrating armature, and a retaining perforation (8), which is matched to...

A composite sheet comprising a fiber base and a binder, wherein said binder is broken into small fragments which adhere to the fibers, but at least some not to each other. Said composite sheet is produced by a method comprising the step of (a) applying a binder to a fiber base and (b) directing a fluid jet stream to the fiber base during or after coagulation of the binder applied thereto. The comp...

A method of extracting an image of a moving object comprises the steps of extracting edge-enhanced input image from an input image taken by an image pick-up element moving in a plane perpendicular to an optical axis, recollecting a background edge-enhanced image from the input edge image, transfer in parallel horizontally and vertically the background edge-enhanced edge image so to correspond to a...

A digital signal transmission system which converts first digital signals having a given bit rate into second digital signals having a predetermined bit rate to transmit them. The first digital signals are written into a buffer memory at a bit rate of the first digital signals, and the written signals are read from the first buffer memory at a bit rate of said second digital signals. The reading o...
