Patent DE-2211785-A1 (DE)
Title: Incorporation of solid additives into pvc - by step - wise polymn of a monomer/additive mixt
IPC: C08F14/06
Filed: 1972-03-10
Abstract: Water-and monomer-insoluble, solid additives (pigments, fillers, stabilisers) are incorporated into PVC by first (co)polymerising the monomer(s) in presence of the additives until 20% conversion is reached; then adding water and opt. water-soluble polymsn. adjuvants (e.g. protective colloid), and finally completing (co)-polymsn. in suspension until the desired degree of conversion has been attained. Additives are homogeneously dispersed throughout the (co)polymer. Separate compounding operation and hence possible thermal degradation of the (co)polymer, is avoided.

Title: Engine with external ignition injects fuel - from cylinder wall, through inlet air flow into pre-combustion chamber with exhaust value
Inventor: PAUSE WERNER DR ING
IPC: F02B19/10
Filed: 1974-09-24
Abstract: The fuel injection nozzle is arranged in the upper part of the cylinder wall such that the jet of fuel is directed at the exhaust valve which is arranged in a pre-combustion chamber outside the opposite cylinder wall in which ignitions means are provided. The arrangement is such that the fuel jet crosses the flow of air entering the cylinder through the inlet valve and produces a pre-heated and ignitable mixture in the pre-combustion chamber. During compression the lean mixture or air present above the piston is moved into the rich mixture where combustion takes place thus producing an intensive mixing action.
