Patent DE-4104418-C1 (DE)
IPC: C08J9/22
Filed: 1991-02-14
Granted: 1992-05-14
Abstract: In order to dry finely divided, expandable styrene polymers having a particle size of from 0.02 to 3 mm, the bead polymers, in the form of a slurry in water, are freed from the majority of the water and subsequently exposed to a gaseous medium. The drying is carried out in two steps, by jointly conveying the bead polymer and a first gas stream, warmed to from about 45 DEG  to 120 DEG  C., through a flow dryer, the ratio between the gas and the bead polymer being from 2 to 40 kg/kg, separating the bead polymer from the first gas stream, immediately transferring the bead polymer into a fluidized bed and treating the polymer with a second gas stream at from about 0 DEG  to 75 DEG  C. Styrene polymers obtained in this way are free-flowing and can be foamed without difficulty in commercially available prefoaming units. They are used, inter alia, in the construction industry, for example as aggregate for insulation plaster.

Title: Symmetrising PWM transformer feeding inverter bridges - involves force switching off electronic switches of bridge branch pairs independently of control
IPC: H02M1/00
Filed: 1991-06-15
Granted: 1992-08-13
Abstract: Single phase inverter bridges feeding transformers and PWM controlled are symmetrised by switching-off, electronic switches (4.1,4.2) of the branch pairs of the inverter bridge (1), conducting the overcurrent independently of the control. The established switched-on duration (T) of the electronic switch (e.g. 4.1), conducting during the last half cycle and now switched-off, is evaluated in the bridge branch pair. The basic initial time, which increases for a selected additional time (deltaT) as a measure for the switched on duration of the other current conducting switch (e.g. 4.2), is valid in the following half cycle in the bridge branch. The switched-on duration for the electronic switches with subsequent release, is increased across the further cycles in steps, for respectively a further additional time, up to the desired value specified by the control. USE/ADVANTAGE - For DC converters, with rapid attainment of the rated control value.

Title: Light wave applicator for cutting and coagulating biological tissue - applies laser beam via flexible optical fibre having non-constant refractive index profile along its cross=section
IPC: A61B18/22
Filed: 1992-01-11
Granted: 1993-04-01
Abstract: The applicator has a flexible light conducting fibre (2). The refractive index profile across the section of the fibre (2) is not constant. Light from a laser (3) is fed into the fibre (2) via a focussing lens (4). At the treatment end the fibre (2) has a free end so it can be accurately guided to the appropriate place in the human body to carry out the necessary treatment according to the adjusted beam angle. Between the feed in end and the treatment end is a manipulator (6). This can accurately provide a curve (8) in part of the fibre (2) for coupling the laser light over regions of different refractive indices. Thus, at the free end the light emerges with a large beam angle (13) for coagulation or, by unbending the fibre, with a small angle (13) for cutting. ADVANTAGE - Allows invasive treatment to be carried out quickly and simply.
