Patent DE-3012133-A1 (DE)
Inventor: NAESSL ROBERT DIPL ING
IPC: H04Q3/54
Filed: 1980-03-28
Abstract: Data is transferred between transmission lines A11 to A1x, Z11 to Z1x and a switching centre EDS via a monitoring circuit MC1 which is one of a plurality MC1 to MCn utilised for handling respective transmission rates. Each monitoring circuit has a microprocessor CPU controlling emission to the switching centre of message signals MP determined by the signalling data received from the incoming lines Z11 to Z1x. This latter signalling data can be in any one of a plurality of formats X20, X70 but each message signal stored in store RAM corresponds to an item of signalling data in each of the formats. Emission of signalling data to the outgoing lines A11 to A1x is dependent on job commands AP from the switching centre, the monitoring circuit being arranged to emit the data in the appropriate format for the outgoing line. <IMAGE>

Title: Underfloor water hydrant - has second valve sealing set for float pressed by spring pressure rod
Inventor: THIEL KARL-JOSEF
IPC: E03B9/12
Filed: 1980-08-21
Abstract: A standpipe connection, sheathing pipe, main stop valve at the bottom of this, and detachably connected valve housing containing a float, are incorporated in a hydrant, esp. of the underfloor type. In the lower part of the valve housing, there is an additional sealing seating for the spherical float which also serves to check return flow. The float lies against a spring pressure rod pressing it against the second seating when water flow is interrupted by the main stop valve and/or standpipe closure. When flow is freed, it is lifted away from this. This permits dismantling when the duct is under pressure, and prevents dirt from contaminating the water.
