Title: A process for removal of volatile components from polymer solutions
Inventor: ELSNER THOMAS
IPC: C08F6/00
Filed: 1998-04-21
Abstract: Volatile components can be removed from polymer solutions without thermal degradation of the polymer in a two-stage process involving heating of the polymer solution, in which all the surfaces coming into contact with the polymer, the polymer solution, and the volatile components consist of a material of Fe content less than 10 wt.%, to give a product with a low content of volatile components. The volatile components of the polymer solution are removed at a temperature above the boiling point of the volatile components and below the polymer boiling point or degradation temperature. In the two-stage process the polymer content is greater the 60 wt.%. In the first stage, the polymer solution is heated to a temperature of 150-400 deg C at a pressure of 1.5-50 bar in channels with an indirect heat exchanger, and the pressure in the channels is then raised to 3-200 mbar, so that the stream in the channels becomes partially two-phase, and the volatile components are partially separated from the polymer. In the second stage, the residue of polymer containing volatile components is separated from the volatile components at a pressure of 0.1-10 mbar and a temperature of 200-400 deg C.

Title: Gas discharge lamp system for running on low voltage busbars has lamps connected to ballast device allowing them to be run at mains frequency and with high frequency voltage.
Inventor: HEYMANN ANDREAS
IPC: F21Y103/37
Filed: 1998-10-20
Abstract: A gas discharge lamp system for running on low voltage busbars is described.

(c) The converter stage is controlled by rectangular pulses whilst the secondary winding of the converter transformer is used as inductance of a high frequency resonant circuit with which the rectangular pulses of the switch converter transistor are converted into the sinusoidal shape. (d) All switch functions for the operation of the discharge lamp are controlled by the combination of two timers run as rectangular wave generators.
