Patent DE-3718457-A1 (DE)
Title: Process for scrubbing out NO and/or SO2 from gas mixtures
Inventor: LASSMANN EBERHARD DR
IPC: B01D53/14
Filed: 1987-06-02
Abstract: A process for scrubbing out NO and/or SO2 from exhaust gases, such as flue gases, is described, which operates with Fe(II) salts or Cu(II) salts in sulpholane. The scrubbing medium, after it becomes loaded, is easily regenerated by heating and/or pressure reduction, after which the scrubbing medium is reusable. A slight reduction in concentration of Fe(II) occurring as a result of oxidation can be compensated for by simple means. The process permits NO and/or NOx to be scrubbed out alone or together with SO2. If SO2 is to be scrubbed out alone from a gas mixture, the addition of salts can be dispensed with. <IMAGE>

Title: Peripheral circuit for a microprocessor
Inventor: PEHRS JENS-ULF
IPC: G06F13/38
Filed: 1987-08-22
Abstract: For data exchange with external units, many common microprocessors require peripheral circuits which are connected to the microprocessor via a number of data lines and control lines. In particular, there are two common microprocessor families, the 8086 type from Intel and the 68000 type from Motorola, which differ in the function of some control lines, particularly in switching between writing and reading. Also, the state of the select signal for the peripheral circuit during switching between the writing and reading state of the peripheral circuit is different. This time response is exploited to switch the function of some control lines, so that the peripheral circuit automatically adapts itself to the type of the connected microprocessor. In this way, the same peripheral circuit can be used for both the given types of microprocessors. <IMAGE>

Patent DE-3740328-A1 (DE)
Title: Personal computer
Inventor: GEBHARDT RALF M
IPC: G06F1/18
Filed: 1987-11-27
Abstract: The distinguishing feature of the personal computer is that its computer unit, power supply unit, floppy disk drive and keyboard unit are implemented as separate components in separate housings. A vertical bus is arranged in the housing of the computer part so that it can receive plug-in cards, including a CPU plug-in card, lying horizontally one over another, on both sides of its longitudinal side surfaces. To dissipate heat from components, particularly chips, and above all CPU chips, which are endangered by heat and produce a great deal of heat themselves, these chips, and above all the CPU chip, are joined on the free surface opposite the connecting pins, flush with and covering the surface, to a piece of heat conducting sheet metal. This in turn is connected to a heat conductor, at the output of which the heat is either dissipated in the computer housing or conducted out of it, particularly on cooling fins.
Patent DE-3744690-A1 (DE)
Inventor: THEER VALENTIN
IPC: F28D1/03
Filed: 1987-05-14
Abstract: A heat exchanger is proposed in whose connecting flanges there is contained at least one threaded blind bore which has a bottom which is at least approximately flat. For this purpose, a drilling (boring) tool which has an at least approximately flat end face and thus a point angle approximately between 150@ and 180@, is used to drill the hole to be drilled to a desired length and as deep as possible and so as to produce a bore hole with a flat bottom in the process. After this, the thread is cut in using a tap which has a flat end face and a cut start which leads over from there to the cut thread and amounts to approximately 1 1/2 of the thread. The result is threaded bores of the greatest possible depth in the flanges in conjunction with a small flange cross-section.
