Title: Cellular material drying process - has temp. control for inner walls of system
Inventor: JEPSON SVEN OLOF
IPC: D21C9/18
Filed: 1980-02-04
Abstract: To dry finely-ground cellular material with a hot gas, such as air or flue gas or steam or gas mixts, the inner walls of the system where the wet material is in contact are held at a temp. equal to or higher than that of the material being dried. The process prevents fibre material from building up on the walls so that material flow is not blocked, and the wall temp. effect is not diminished. Heat is fed from an external source to the system walls to keep them at the required temp. The hot gas for drying the material is passed wholly or partially through the fibre loosening equipment so that the passage of the material and the heat transfer during the setting phase is eased.

Title: Stereoscopic image reproduction by spatially separated representation of image information for the left and right eye on a display screen and different polarisation of the light intended for the left and right eye
Inventor: BLIN ALEX H DR
IPC: G02B30/25
Filed: 1982-04-19
Abstract: In television engineering, the image is represented on a display screen in a linewise fashion, to be precise sequentially as two interlaced fields. The invention consists in that one field is provided with information which is intended for the left eye, and the other is provided with that for the right eye. The display screen is covered with polarisation filter strips in such a way that the light originating from the lines of the first field is polarised perpendicular to the light which originates from the lines of the second field. The image information is fed separated once again to the eyes by means of spectacles with polarising lenses. The image appears to be stereoscopic. The principle can be applied analogously to other geometries for the position of the fields.
