The first arm (10) is rotatably mounted about a first pivot (9) which is perpendicular to the work surface (41). The device (14) to be positioned is arranged at the end of the second arm (12). The first pivot (9) is driven via gearing (7, 8) by a first motor (6). The first arm (10) is connected to the second arm (12) via a second pivot (11) which carries a spring (13) which presses the two arms (11, 12) against one another. A second motor (21) is provided in extension of the first pivot (9), a cable (20) being wound around the shaft of the second motor (21), the start of which is firmly connected to the shaft of the second motor (21) and the end of which is fastened to a bolt (19) at the end of the second arm. The device (14) to be positioned can be taken to any point of the work surface (41) by the controlled actuation of the motors (6, 21). Alternatively, the second pivot (11) can be driven via a third motor (40) and gearing (38, 39), in which case the second motor (21), the cable (20), the bolt (19) and the spring (13) are then omitted. <IMAGE>

Patent DE-3228884-A1 (DE)
Inventor: LOHRBERG KARL DIPL ING
IPC: C25B9/19
Filed: 1982-08-03
Abstract: In gas-forming electrolyzers, particularly membrane electrolyzers having vertically extending plate electrodes, each electrode plate is divided into horizontal strips and the entire active electrode surface is parallel to the counterelectrode and spaced from it as closely as possible. The top portions of each of the horizontal strips into which the electrode is divided define gas escape paths and extend away from the counterelectrode. To improve the degassing of the electrolyte the ratio of the distance G between the counterelectrode or membrane and the gas-defining line S at the lower edge of each electrode strip to the distance E between the counterelectrode or membrane and the breakaway edge K of the angled portion defining the gas escape path corresponds to a degassing capability F which is lower than 0.6.

Title: Information device for the passenger compartment of public transport means
Inventor: SANDER HEINRICH DIPL ING
IPC: G09F13/04
Filed: 1982-03-17
Abstract: The information device provides passenger information in public transport means. It essentially comprises a flat display component (AB) to hold a multiplicity of luminous elements (L) and an information carrier (J) fitted to the latter. This information carrier provides diagrammatic route display. Specific stops (A to H) can be visually marked on it through the selective activation of luminous elements. The marked stops help the passengers to identify locations and are intended to enable the passengers to prepare in good time to disembark. The information carrier (J) or the display component (AB) as a whole are interchangeable, so that other routes can also be travelled if required. A converter permanently assigned to the respectively travelled route or line allows the luminous elements of the display component to be activated in the order in which they are assigned to the consecutively reached stops. <IMAGE>
