Title: Solvent recovery - by activated carbon bed adsorption and desorption by membrane sepn. and condensation
Inventor: PAUL HELMUT DR ING
IPC: B01D53/04
Filed: 1989-10-21
Abstract: A process to separate solvent contained in the outgoing air from lacquer spray cabins and to purify the waste air is based on the passage through activated carbon.  The latter is regenerated by hot gas resulting in a desorption gas circuit which is conc. by a membrane sepn.  The solvent is finally extracted by condensation. The waste air is passed through a slowly revolving rotor (2) with an activated carbon bed (3) which has a large adsorption zone (6) and a small desorption zone (7).  The desorption gas is heated to 120-150 deg.C in two heat exchangers (19, 20).  Cool air (8) from a blower (9) helps to cool the bed.  The desorption circuit (10) passes through a membrane separator (11).  The permeate gas circuit (15) loses the solvent by condensation in a freezing trap (25). ADVANTAGE - This causes no emissions because both desorption and permeate gas flows from closed loops.

Title: Optic fibre preform - is made from quartz tube in moving graphite furnace with optical control and min. gas flow for MCVD cladding
Inventor: GLESSNER BERTRAM
IPC: G01D5/34
Filed: 1990-01-19
Abstract: To produce a preform for optical fibres, where the interior of a quartz tube is cladded using a graphite resistance furnace which deposits a layer on each pass, a diaphragm is used to determine the ring gap between the quartz tube and the graphite insert. The position and opening is regulated by optical metering in relation to dia. and centre point position that the free gap (11) is as small as possible and the diaphragm does not touch the tube. At the same time, the flow of protective gas in the furnace is adjusted to give the lowest possible flow of gas pasing down from the top in the zone (12) between the graphite insert (13) and the tube (1), but sufficient to prevent contamination of the graphite insert (13). ADVANTAGE - The method reduces deviations from the required standard as far as possible in terms of core eccentricity and ovality in the quartz tube. The lowest possible gas flow is used with rotary symmetrical passage between the quartz tube and the graphite insert.

Patent DE-4016886-A1 (DE)
Inventor: CHAUVIN JACQUES DIPL ING
IPC: H04N17/04
Filed: 1990-05-25
Abstract: A method of collecting the spactial positions of crossing points of the lines in the grid on the visible portion of the screen of a television receiver used in different modes of operation includes the steps of storing a first set of correction values for each of the crossing points. The first correction values define the spactial positions of the correction points for all modes of operation of the television receiver. Additional correction values are stored for each mode of operation. The additional correction values are generated during an overscan period and during the scanning of an initialization line which is positioned outside the visible portion of the screen and compensate for displacement of the crossing points induced by tolerances in the tube. The first correction values and the additional correction values are simultaneously applied to the deflection current of the television tube while the visible portion of the screen is scanned.
