Patent DE-2935898-A1 (DE)
Inventor: FIVAZ ROBERT
IPC: G01B7/12
Filed: 1979-09-05
Abstract: The rotary transducer for position measurement is normally used in conjunction with a cylindrical rectifying machine for auto-calibration of the machined article. It may comprise one or two axes of rotation (2) each carrying an arm (3) whose particular feature is that the free end carries a measurement key (4) of cylindrical shape (preferably a cylinder of revolution) with generatrices parallel to the axis of rotation (2). Thus, the measurement of diameters of articles (5) is independent of the precision of relative positioning of the transducer with respect to the article, the article (5) no longer having its axis (6) parallel to the axes (2). This eliminates the precision constraints imposed on the linear bearings of radial translation mechanisms supporting the transducer. <IMAGE>

Patent DE-3024640-A1 (DE)
Inventor: ROTH ADRIAN W DIPL ING
IPC: H01H33/915
Filed: 1980-06-30
Abstract: In the case of the described gas-blast circuit breaker, the stationary contact element (2) is surrounded by a cylindrical wall (12) which is provided with a perforation (9) in the end region facing away from the blowout nozzle (5, 5'). The switching arc causes a pressure rise on the inside of this wall (12). The fresh gas is pushed from the inside of the wall, via the perforation (9), into the space (11) located between the outside of the wall (12) and the housing (1). Between the lower end of the wall (12) and the spring-loaded, axially displaceable blowout nozzle (5, 5') a gap is produced when the pressure in the space (11) is sufficiently high with respect to that in the blowing-out space (19). Fresh gas can flow out of the space (11), through this gap, to the blowout nozzle when the moving switching element (3) has released the blowout nozzle. This economically advantageous gas-blast circuit breaker has good switching properties and operates without arc-back in all current ranges. <IMAGE>

Patent DE-3025330-A1 (DE)
Inventor: GRUNST HEINZ
IPC: H02B1/48
Filed: 1980-07-04
Abstract: In devices for mounting electrical devices, in particular switch, command or signal devices on a plate, like a bottom plate of a switch box or an assembly plate of a switch box or switch board of the type with at least one mounting bar for the devices disposed parallel to the plate as well as with two vertically-extending supports mounted on the plate for each mounting bar and with screw connections between the supports and the mounting bar, the difficulty exists that it is hard to reach the screw connections between the supports and the mounting bars, because of tight space conditions due to a tight arrangement of the devices relative to each other and due to the wiring which leads to the devices. In order to be able to obtain a simple servicing and safe support of the mounting bars on the supports, even at the tightest space conditions, it is proposed to provide screws which are disposed vertically with respect to the plate and which cooperate with clamping plates which are so designed that by tightening the screws, the supports are rigidly connected with the mounting bar due to the clamping effect.
