Title: Spark ignition IC engine - has second inlet valve with variable timing to increase part load efficiency
Inventor: VOIGT DIETER DIPL ING
IPC: F02D13/02
Filed: 1979-01-13
Abstract: The engine has two inlet valves for each cylinder. One of them is timed in the usual way. The other has a drive which allows its timing to vary with the load on the engine. At full load the variable valve opens at the same time as the normal valve. As the load drops the time at which it opens is progressively delayed. The time during which it is open remains constant. The variable valve thus remains open during part of the compression strke and reduces the total charge taken in by the engine with a resulting increase in efficiency at part load.

Title: Removal of components such as chloride from liq. samples - using recirculated air stream into acidified sample to strip out hydrogen chloride while returning organic trace materials
Inventor: SCHIERHOTT GUENTER DR TECHN
IPC: B01D19/00
Filed: 1979-08-10
Abstract: Components in a liquid sample which contains organic components can be removed if they interfere with the desired analysis. The undesirable components are first converted to the form of a dissolved gas which is then stripped out by bubbling a carrier gas through the sample. The gas flows over into a coller sepn. zone where the stripped out component condenses. Any organic material taken with the carrier gas is returned to the sample via the gas circulation pump. The process is of esp. use to remove chlorides from liquid samples. The gas recirculation ensures that the more volatile organic components are not lost from the system.
