Patent DE-2159836-A1 (DE)
Title: Composite paint system - esp for car bodies with significantly reduced solvent content
Inventor: NIEHAUS CLEMENS DR
IPC: B05D7/14
Filed: 1971-12-02
Abstract: The sheet metal is either pretreated by conventional means or may be untreated, and is primed by electrostatic powder spraying, using a wide range of solvent less materials; those parts of the metal which escape coating due to the formation of Faraday cages are then primed by electro-chemical dip painting using similar paints chemically, to the powder. After stoving, a finishing coat may then be applied. The powder coat may be flowed by heating to 120-160 degrees C before the E.C. coat is applied and the two are then hardened simultaneously at 160-210 degrees C. Better resistance to chipping by stones etc. and reduced atmos. pollution by redn. in use of organic solvents are achieved.
Patent DE-2160157-A1 (DE)
Title: Removing sodium hydroxide contamination from - electrolytically produced hydrogen - by means of cation exchange resi
Inventor: TODEREANU CORNELIU
IPC: C01B3/56
Filed: 1971-12-03
Abstract: Purification of electrolytically produced hydrogen is improved by using a cation exchange resin to remove NaOH from the moist hydrogen, and an anion exchange resin to filter the water used for moistening the hydrogen; the moistening water is recycled. Hydrogen so purified is suitable for catalytic hydrogenation. Very effective method (an original NaOH content of 1-20 mg./Nm3H2 is reduced to traces). The size of the apparatus is relatively small, and so is the consumption of energy. No toxic effluents. Hydrogen is passed through a layer of a cation exchange resin moistened with water, which is recycled through a filter consisting of an anion exchange resin to adjust the pH to an approximately neutral value and, hence, avoid corrosion of the apparatus.

Title: Energy recovery from pressure electrolysis - utilises hydrogen pressure to raise water
Inventor: MACHOWETZ WOLFGANG DIETER
IPC: F24V50/00

Title: Drive system with hydraulically operated coupling - engine speed is automatically suited to hydraulic working pressure to prevent slip
Inventor: MACHENS KARL-HEINZ DIPL ING
IPC: F16D25/08
Filed: 1974-05-22
Abstract: The engine speed regulator lever (2) is connected to the manual control lever (3) via a hydraulic piston and cylinder combination whereby the manual lever rod (6) is connected to the cylinder (4) and the engine speed regulator lever (2) is coupled to the piston (5) rod (7). The cylinder is provided with end stops (13, 14) to limit the pistons movement. The piston has a return spring (8). The cylinder chamber (9) is connected to a hydraulic supply containing a restrictor (11) and a non return valve (12). At normal working conditions, the hydraulic pressure is sufficient to press the piston against the spring to the end stop (14). Should for any reason the hydraulic pressure drop, the piston will move to its other end stop thus decreasing the engine revolutions to a level by which it is just possible to manoeuvre the vehicle in low gear without damage to the clutch.
