Inventor: OPPERMANN HANS
IPC: B32B29/00
Filed: 1978-01-07
Abstract: In laminates of paper and/or woven and/or nonwoven fabrics impregnated with unsatd. polyester resins, the resin is 40-80, pref. 50-70% cured and contains 0.2-4 pref. 0.5-2 wt % peroxide(s) (I) with a half life of min. 10 h at 100 degrees C pref. min 10 h at 120 degrees C. The laminate pref. is 0.3-4 esp. 0.5-3 mm thick.

Title: Detection of leaks in underground water pipelines - uses pipe section separated from normal water supply and connected there to via measuring line
Inventor: JAECKLE EUGEN
IPC: F17D5/02
Filed: 1978-02-22
Abstract: The measuring line used in the leak detection process contains a meter. The pressure in the measuring line or the water flowing through the line per unit of time is recorded over a longish period. The instrument for making the measurements can be accommodated in a motor vehicle. To carry out the measuring operation, all the slide valves in the area concerned are closed. Lines are carried to the hydrants (3', 3", 3"'). Water is now conveyed through the measuring line (100) and is drained off through the measuring line (100"). The water flow is measured through both lines.

Title: Anticorrosion treatment of galvanising vats - by thermal spraying of cobalt or ceramics
Inventor: STING WERNER
IPC: C23C4/08
Filed: 1978-03-28
Abstract: The inside walls of galvanizing vats suffer severe corrosion and the service life of a vat, even if produced from low-silicon special steel, varies from 2 to 5 years. The life can be extended many-fold by plasma spraying of cobalt, a high-cobalt alloy or ceramics. Rods or powder can be applied in a plasma flame or in a gas heated spray gun. A layer thickness of 1-2mm is normally adequate but can be increased in case of mechanical stress. Before the spraying, the surfaces are best shotblasted. A subsequent annealing improves the adhesion by sintering.

Title: Rescue appts. for use on high rise buildings - has cantilever beam with pulley on free end and cable wound on drums (OE 15.4.79)
Inventor: HOLDERMANN ROBERT
IPC: A62B1/02
Filed: 1979-03-17
Abstract: Each drum accommodates half of the entire cable length. The support assembly is suspended also by a further cable which is led over a deviating pulley and a wind-on cable drum fitted with a band brake operated by lever. The operation of the band brake is assisted by an additional brake actuated by movement of the pulley on a spring loaded lever. The smoothness of the lowering operation is controlled by the action of two brake shoes exerting a continuous braking action on both drums. In case of sudden deceleration of the assembly weights by their intertia increase the pressure on the brake shoes and stop any further descent.

Title: Improving utilisation of digestion tank volume - by sludge dewatering before, during or after digestion
IPC: C02F11/127
Filed: 1980-06-11
Abstract: The available vol. of a digestion tank in a sewage treatment plant is utilised to better advantage by extracting the part of the moisture content which is not required for the digestion content, through a mechanical device. The substrate to be digested, esp. sewage sludge, can be treated for dewatering before, during or after the digestion process. The method of dewatering depends on the constancy of the sludge. In homogeneous raw sluge is best treated in a filer and flocculated biological sludge is best dewatered by a centrifuge. This makes better use of existing digestion tanks and permits the design of smaller types for new installations, thus saving much capital expenditure.
