Title: Effluent sulphur dioxide entrapment
IPC: C01B17/05
Filed: 1970-09-15
Abstract: The effluent gases are passed into an aqueous suspension of a mixture of finely divided particulate mineral acid reactable alkaline earth metal contg. 3-4 wt. parts of mixed metallic oxides and 2-3 wt. parts of silicates, the oxides and silicates being of Grps. IA, IB, VII metals or Ca, Mg and Mn, the suspension having a pH of 8-9. The suspension is agitated to form sulphurous acid, sulphito salts and dihydrated silicic acid.

Patent DE-2316252-A1 (DE)
Title: Safety closure for pressure vessels - in which internal pressure closes a bolt in the cover
Inventor: HEYNOLD WOLFGANG
IPC: F16J13/24
Filed: 1973-03-31
Abstract: The cover of the vessel has an internal bore contg. a horizontal piston and spring-loaded ram. A pressure medium entering the bore forces the ram aong to engage in a hole in the wall of the vessel where it locks in position, thereby exposing an overflow hole in the bore to the interior of the vessel. While the interior is under pressure, the cover therefore cannot be opened. Release of the pressure allows the spring to force back the ram, and so free the cover.

Title: Needle remnants detection in roughened textile webs - by unbalance of capacitance-inductance oscillator circuit
Inventor: BEYERL PETER
IPC: D06C13/00
Filed: 1973-08-10
Abstract: A metal detector to establish the presence of fractured needles in a web of textile material roughened by a needle bed consists of a capacitor which is a part of an oscillator circuit.

Title: Asymmetry of tyres or wheels measuring device - evaluates periodic electric signals generated by the wheel rotation using fourier analysis
Inventor: REUS WALTER
IPC: G01M17/013
Filed: 1973-11-16
Abstract: A sine-cosine potentiometer generates functions f(x). cos nx and f(x).sin nx. Its shaft is connected to the tested wheel shaft. Both potentiometer output signals are applied to RC circuits for the mean value formation. Their time constant is large in comparison with the wheel revolution; RC circuits are followed by impedance transformers, and a store consisting of an RC circuit and impedance transformer can be disconnected from the potentiometer, and the two stores' output signals vectorially added and applied as test values to a display device. A device connected after disconnection of the stores from the potentiometer finds the high or the low point on the wheel periphery. Its vectorial output signal can be adjusted by changing the relative positions of the potentiometer and sheel, to match the test value applied to the display device.

Title: Vehicle powered by combination of IC engine and battery - uses large generator as electric motor when running on battery
Inventor: FRIEDEL KARL
IPC: B60L11/00
Filed: 1974-01-08
Abstract: The vehicle has a front mounted IC engine for inter-city travel and a rear mounted battery for clean, emission free city travel. A multi-purpose electric motor is fitted between the IC engine and the gear box.
