Title: Reinforcing fabric for road construction - has flat yarns at crossover points bonded by dipping to give good resistance to thread slippage due to thermal stresses
Inventor: AISSLINGER DIETER
IPC: E04C5/07
Filed: 1991-07-12
Abstract: A reinforcing fabric for road construction has the cross-over points of the longitudinal and crosswise threads only partially interleaved and does not use a wrapping thread. The fabric is pref. dipped in several stages, with the first dip with low solids concn. forming a base layer between the crossing threads and a second dip consisting of a dispersion of bitumen, acrylates and/or other synthetic mixts. forming a surface layer. A fabric consists of longitudinal (7) and crosswise (8) bundles of filaments which are flat at the cross-over points (11) with only a few filaments interleaved. The fabric is first dipped into a bath of special pigmented wetting agent with low solid concn.. Some particles are deposited at the cross-over points to form a base layer for the surface layer applied in a second dipping process. This is a dispersion of material resistant to the diffusion of damaging substances, such as fuel additives, and can be bitumen, etc.. A layer up to 0.09mm thick is formed and provides the bond for the cross-over points. USE/ADVANTAGE - Reinforcing fabric with greater resistance to thread slippage arising from thermal stresses.

Title: Reduction of water consumption in buildings - using pump and valves, to feed cold standing water in hot water pipes into cold water pipes
Inventor: WORTMANN WILHELM
IPC: F24D17/00
Filed: 1992-06-13
Abstract: The arrangement is for use in buildings with centralised and/or non-centralised hot water supply. In periods in which no hot water is extracted, the water in the pipes between heater and consumer is maintained stationary, and is not circulated. Until the hot water reaches the extraction point, the cooled water from the hot water pipes is fed into the cold water pipe. This is achieved by pressure differentials, and extraction valves (6) and/or overflow pipes and valves. A pressure differential, e.g. excess pressure, is generated by a pump (8) with e.g. electric motor drive and an electromagnetic valve. USE/ADVANTAGE - Water consumption reduction system can be used in new and existing buildings. It permits hot water to be extracted from tap without loosing cold water.

Title: Clamping device for hydraulic pusher system - useful for sideways displacement of heavy load, e.g. bridge
Inventor: DITTRICH JOERG
IPC: E21B15/00
Filed: 1992-11-09
Abstract: In a clamping device for a hydraulic pusher device displaceable on a f- or I-beam for moving heavy loads, part of a piston-cylinder unit causes parallel swivelling, during force transmission to the load, of clamping elements extending about the beam flange sides so that the swivelled clamping elements clamp solidly on the flange top and bottom.

Title: Chemical-physical and biological physical cleaning of soil - comprises mixing with water, coarse material is separated, and sludge is sedimented and biologically treated using fluidised bed procedure
Inventor: MENSCHEL CLAUDIA DR
IPC: B09C1/02
Filed: 1993-02-06
Abstract: In a new procedure for cleaning contaminated soil: the soil is mixed with water in a reactor (1) in a ratio of 1:2 to 1:10 by means of at least two air/water agitation operations (2), so that the impurities are transferred to the resulting sludge or artificial sludge substitute; sludge and microorganisms are separated from the coarser material by reducing the turbulence (3, 5) and by changing the direction of flow, the resulting clean coarse material is removed (4); suspended materials are removed (6) from just below the liquid surface and are taken to a settling tank (7) with a dwell time of about 1 hr., in which the suspended material flows upwards through a bed of the separated sludge and is filtered by it; the water which is free of suspended materials is withdrawn (14) at about 20 cm below the liquid surface and is returned to the inlet of the washing system; floating materials and oils are removed (13); the sedimented foam and microorganisms (12) are introduced into an aerobic fluidised bed in which organic contaminants are broken down by microorganisms specific to them; if heavy metals are present, the sludge from the settling tank or reactor undergoes an elution procedure by which the heavy metals are separated; and the clean sludge is mixed with the previously separated coarse material. Also claimed is an appts. for carrying out this procedure. USE/ADVANTAGE - For cleaning soils or other granular materials which have a grain size less than 20 mm and are contaminated with organic materials, nutrients or heavy metals.
