Title: Printer ink for thermal-converter printing head
Inventor: BUDDE KLAUS DR
IPC: C09D11/30
Filed: 1988-07-22
Abstract: For a thermal-converter (thermocouple) printing head, an ink is specified which contains     from 40 to 60 parts by weight of water,   from 25 to 35 parts by weight of diethylene glycol,   from 2 to 6 parts by weight of polyethylene glycol, from 10 to 20 parts by weight of 1-methyl-2-pyrrolidone, and one or more soluble dyes, where the solvent components are in equilibrium concentration with respect to the equilibrium reaction between diethylene glycol, water and polyethylene glycol (by condensation). This provides a self-stabilising solution which, in conjunction with the dye Food Black 2, achieves outstanding results in a printer, with good drying properties and improved light fastness. In addition, the ink is readily compatible with the printing head and does not corrode metal components, and the flight pattern of the ink drops is unchanged even after a long-term printing test.

Title: DC-isolated DC/AC converter (invertor) having high efficiency
Inventor: ZERBS WINFRIED DIPL ING
IPC: H02M7/797
Filed: 1988-08-27
Abstract: A pulsed DC-isolated DC/AC converter is disclosed, the output voltage of which simulates a predetermined target signal. In order to achieve high efficiency in the case of differing loading of the output, four pulsed converter systems (switches S1, ..., S4) are provided, two (S1, S2) of which are used for transmitting the energy and two (S3, S4) of which are used for feeding back the unneeded energy, in order to allow four-quadrant operation. Two separate transformers (Ü1, Ü2) are used, one of which is in each case used for the energy transmission and the other for feedback. If an additional winding for feedback is arranged on each of the two transformers, then the feedback rate can be optimised. Special feedback transformers are obviated. <IMAGE>

Title: Controlling the carbon dioxide concentration of space stations
Inventor: MICKELEIT MICHAEL DR
IPC: B64G1/48
Filed: 1988-11-12
Abstract: A method which serves to control the carbon dioxide concentration in the gas atmosphere of a space sealed in a gas-tight manner, especially of an orbital station, comprises bringing a carbonate of an alkali metal, alkaline earth metal or metal in a reaction chamber to a temperature at which the equilibrium pressure established of the carbon dioxide which is formed owing to a reversible dissociation of the carbonate into the corresponding oxide, reaches the value of the partial pressure corresponding to the preset concentration. This temperature is kept constant by means of a control device which forms part of a heating device appertaining to the reaction chamber.

Patent DE-3906222-A1 (DE)
Title: Electronic method for improving the quality of a line image
Inventor: NITSCHE ERHARD
IPC: H04N1/053
Filed: 1989-02-28
Abstract: This line image is picked up by means of a detector and refractive or reflective scanning elements. Production tolerances in the scanning elements lead to each line beginning at a different time, and the consequence is a striped line image. The signal of each line can be delayed by means of a suitable delay circuit which must be individually dimensioned for each scanning element, in such a manner that all lines have a common zero point in time. This eliminates the striped structure of the line image.

Patent DE-3940524-A1 (DE)
Title: Carrier air control
Inventor: FAAS JUERG
IPC: D01B3/02
Filed: 1989-12-07
Abstract: To control the operation of carrier air, such as for the movement of fibres from a bale breaker through a cleaning stage and on to carding for a spinning process, pressure sensors measure the static pressure at critical areas and, on a deviation from nominal values, trigger a correction to bring the pressure into or towards the nominal range. The corrections to the pressure in the critical area are transferred to other sections which are subject to them. The measurement and correction process is repeated until the-e measured static pressure matches the nominal pressure. Pref. the control steps are structured so that temporary deviations are disregarded. During pressure adjustment, when the measured pressure enters the nominal range zone, the corrective action ceases. The pressure in the critical areas is monitored at time intervals to be regulated and readjusted, at time intervals from one day to several months, and pref.  once a week.
