Title: Pressure-tight terminal connection
Inventor: WEISS FRIEDRICH DIPL ING
IPC: F02M51/04
Filed: 1988-08-10
Abstract: A pressure-tight terminal connection between a solenoid valve (20) and a fuel injection pump (44) comprises a clamping flange (33) fixed to the valve or pump housing and a hollow cylindrical clamping nut (34) with internal thread (36) and an inside diameter, sufficient for passage of the clamping flange (33), overlapping the clamping flange (33). The clamping nut (34) is provided inside with a circumferential depression (37) with radial clamping shoulder (38) on which, when the clamping flange (33) is held in place, a joint-free retaining ring (39), having only a minimum parting gap (50) and acting on its rear side, is supported. An undercut (42), into which the retaining ring (39) can slip when the clamping flange (33) is pushed through by the clamping nut (34) and retaining ring (39), immediately adjoins the depression (37). For introduction of the clamping ring (39) into the undercut (42), the clamping ring (39) is twisted in the parting gap area by means of an assembly tool (80) and is pushed through the through-opening (48) in the clamping nut (34) up to the undercut (42). <IMAGE>

Title: Compound sliding and rolling mat
Inventor: SCHULTE KLAUS DR
IPC: E21D11/15
Filed: 1988-09-23
Abstract: A compound sheet which can be folded like a concertina is provided for roadway support. Lagging bars are integrated in the compound sheet at a distance apart and are formed in such a way that it can be placed on the support arches without a direct connection to the neighbouring compound sheet. The lagging bars are bent at the ends in accordance with the centre distance between arches. They are fixed in the lagging sheet in such a way that they cannot rotate, as a result of which reliable engagement in the support section is obtained. The lagging sheet with lagging bars, support arches and consolidating construction material thus produce robust compound support. <IMAGE>

Title: Tube (tubular, bulb, Kaplan) turbine with axial passage of water
Inventor: BERGER GUENTER DR ING
IPC: F03B11/00

Title: Circuit arrangement for outputting binary signals
Inventor: KNAUER DETLEV DIPL ING
IPC: H01H47/00
Filed: 1989-03-10
Abstract: For outputting binary signals in process control systems and process management systems, use is made of electronic switches (TS1...TSn), a multiplicity of which are generally combined with their drivers (TR1...TRn) in a module or in an integrated circuit. Voltage overshoots when disconnecting inductive loads (LR1...LRn) are prevented using suppressor (anti-surge) diodes (LD1...LDn). In the event of a break in the supply line (VL1) of the drivers (TR1...TRn) its supply current flows via the suppressor diodes (LD1...LDn) through the load (LR1...LRn) and can therefore trigger output functions, for example cause response of a relay or prevent release of relays. In order to avoid this, according to the invention a voltage monitoring circuit (SV) is provided, which monitors the supply voltage of the drivers (TR1...TRn) and, in the event that it falls below a predetermined magnitude, switches off the supply current of the driver. The invention is used in binary outputs of process control systems and process management systems. <IMAGE>
