Title: Engaging central office set in PBX installation - uses central control, triggered by first or second instruction, releasing internal terminal on office set engagement
Inventor: DEMUYNCK NOEL
IPC: H04Q3/62
Filed: 1990-11-30
Abstract: The PBX has a central control (ZR) and a memory (SP CNFG, CNCP) for installation configuration data and connection state information.

Title: Rail road bed - uses liq. mortar to form a plate in upper section of the ballast, with structured ballast particles to prevent downwards dispersion
IPC: E01B1/00
Filed: 1991-02-15
Abstract: To form the roadbed of a twin-track permanent way, such as for railways, the ballast (2) is bonded with liquid mortar to give a plate running through the upper section (5), restricted to the required height for a given structure. The lower section (6) is composed of loose ballast, with a max. particle size equal to the slip particles of the laid coarse ballast, to prevent the liquid mortar from dispersing into the lower zone. The loose material is placed only in areas requiring drainage or as a seal against the supporting ground. Cement can be added to the loose material. To prevent the liquid mortar from seeping from the sides of the ballast, as it is applied after the reinforced concrete sleepers have been laid, a sealing (7) is fitted to the sides to be held in place by earth pins while the plate is cast for the upper section (5) of the laid ballast. The side sealing can also be inserted into slits formed in the ballast on each side of the laid sleepers, using inserted rolled material which can be recovered. The sloped sides of the ballast can also be sprayed with a sealant, which in turn is covered by surplus ballast material to keep it in place. The ballast can be laid so that it has a stepped particle structure and a reduced hollow zone between the particles. ADVANTAGE - The technique gives a stable ballast for the permanent way, and prevents excessive use of liquid mortar.
