Patent DE-2447855-A1 (DE)
Title: Thermionic detection of specific substances in liquids analysis - using burner with spray feed of liquid into flame
Inventor: KOLB BRUNO DIPL CHEM DR
IPC: G01N27/62
Filed: 1974-10-08
Abstract: A method of analysing liquid mixtures to detect substances comprising predetermined constituents consists of introducing the mixture into the flame of a thermionic detector. The mixture is sprayed, esp. as a mist or aerosol, into the flame of a thermionic detector which responds specifically to the intended constituents to be detected. Preferably, the mixture is subjected to liquid chromatography separation and the eluate from this separation is continuously sprayed into the flame. Used for example, for the specific detection of halogens, phosphorus and nitrogen. Improved sensitivity for the constituents is obtained with suppression of disturbance signals; also the influence of the solvents is eliminated. No mechanical parts project into the flame which could result in disturbance of the detector function.

Patent DE-2456580-A1 (DE)
Title: Engine ignition system
Inventor: HABERT ROGER
IPC: F02P3/045
Filed: 1974-11-29
Abstract: The ssytem is particularly for motor vehicles, incorporating a high-tension coil. A first voltage is generated proportional to the angular discrepancy between a reference value and the variable angular setting of a rotary component driven in proportion to engine speed. A second voltage is also generated, its value being a function of engine speed. When the sum of these two voltages coincides with a threshold voltage of constant value, a control impulse to start excitation of the ignition coil is generated.This results in an overall time for the necessary, sufficient and controlled current in the coil independent of engine speed which limits current consumption at low speed, and particularly when the supply voltage is increased
