Title: Acid, basic or neutralising power output prodn. - by explosive gas principle using hydrogen and helium
Inventor: HORNDASCH FRIEDRICH
IPC: C01B23/00
Filed: 1977-04-28
Abstract: The process involves reacting H2 with He instead of O2 and initiating the reaction by thermal activation of the H2 and/or He. It is pref. to use 8 pts. wt. He with 1 pt. wt. H2, to give an intended balance between the basic and the acidic power output of the 2 prim. gases. The natural acid power output of each proton from H2 is 1 cal/g., whilst the basic power output of each neutron from He is 1/8 cal/g. Not only the mass discrepancy (ratio 1:4) but also the mass difference between the prim. H2 and the O2 produced from the prim. He in the ratio 1:16 is effective and produces different power outputs.

Patent DE-2843996-A1 (DE)
Title: Solar heat collector - with plastic hose for heat transport medium contacting blackened metal plates
Inventor: BOETTCHER ALFRED PROF DR
IPC: F24S10/75
Filed: 1978-10-09
Abstract: In a flat solar heat collector, the incident thermal energy is absorbed at a rate of 30-100% by a blackened metal element which in turn transfers it by heat conduction and convection to an easily deformable plastic hose. The heat transport medium, e.g. water for a hot water system, flows through the hose. If the plastic hose (silicon rubber) is enclosed between two metal plates, their distance is smaller than the hose dia. so that the hose is deformed to an oval and contacts the meal with 10-50% of its surface. Over 60% of the total hose length is enclosed between metallic surfaces. If the hose lies on top of a metal plate, the hose is partly blackened to absorb a part of the solar energy directly, at a rate of 20-70%. Over 60% of the hose length is arranged to lie in the same plane. Such a collector is simple and can be produced at low cost.

Title: Printed circuit boards - mfd by applying elastic adhesive coating for conductor tracks and soldering tags
Inventor: KOENIG WERNER
IPC: H05K3/38
Filed: 1978-12-30
Abstract: Printed circuit boards are produced by applying the conductor tracks and the soldering tags to an insulating plate. The insulating plate is first coated with an elastic adhesive layer, pref. consisting of a phenolic resin, combined with synthetic rubber. This layer is dried at room temp. or pref. by air or oven drying at 180 degrees C. The conductor tracks and soldering tags are then applied to the coated plate, for example by a screen printing technique. This produces a four-times better adhesion than vapour deposition or mask etching techniques. The new method costs less and creates no pollution problems like etching or vapour deposition techniques.
