Title: Colour photocopier material - uses transparent paper sets with extended black steps to give different shading(s)
Inventor: SCHLOEMER ELISABETH
IPC: G03G15/00
Filed: 1990-11-29
Abstract: The transparent paper set, extended in stepped black sections as original material for colour photocopiers, are displaced during copying by steps to give different grey areas which are each consistent within themselves and are transparent, or colour surfaces with different brightnesses. Pref. the transparent paper set, with the same number as the clear films, are inserted between each film to carry the extended black areas.

Filed: 1992-04-24
Abstract: The two-stage biological cleaning process for waste water, with components from cellulose ether prodn., takes a mixture of recirculated water and raw water through a rotating distributor to mix through bulk elements of bacteria growth 2-8mm thick. Air is fed through in a counter stream for contact with it, with an oxygen content of 13-19%. The recirculated water vol. is used at a rate of 2-20 times the raw water vol., and pref. 3-7 times. The oxygen content of the air is adjusted by exhaust air feedback, which is controlled for its methane content. The distributor rotates at a speed of 3-30 rotations/hr., and the rotating speed sets the thickness of the bacteria growth. The bacteria growth thickness is measured by weight, and is used to set the rotary speed of the distributor. USE/ADVANTAGE - The waste water contains carbohydrate derivatives such as hemicelluloses and ethered short-chain celluloses.
