Title: Frame for receiving component boards without conductors
Inventor: NIEMANN WERNER
IPC: H05K9/00
Filed: 1981-03-20
Abstract: The invention relates to selectively etched frames (cutouts) for receiving component boards without conductors in circuit boards of stacked individual foils. In the accommodation of component boards without conductors and their proper connection to the printed conductor tracks on the individual foils, different requirements have to be fulfilled in order to achieve an improvement in the production process in terms of automation.   1) In order to ensure that when they have been supplied, the component boards and their connections, consisting of metallised channels with moulded-on soldering tracks (1), are held in a complementary position relative to the beaded metal tongues (2), the elastic plastic lips (3) are matched to the dimensioning of the board housing. 2) The beaded, if appropriate overlapping, metal tongues form channels with the metallised profiles on the component board housing, into which channels the solder is sucked by activating the capillary effect to produce discrete solder connections (4). 3) A limited zone (5) around the receiving section of the stacked foils remains free of bondings and thus flexible in order, in conjunction with the elastic plastic lips (3), to absorb forces from different temperature coefficients (ceramic housing versus plastics substrate).

Patent DE-3122909-A1 (DE)
Title: Simple locating system for testing sound emission
Inventor: GREIFF RUDOLF DIPL PHYS
IPC: G01N29/14
Filed: 1981-06-10
Abstract: In order to locate sound emission signals even in thick bodies and without knowledge of the velocity of sound, a number of sound receivers (probes) are fixed in an open, preferably linear arrangement and/or in a closed, preferably circular arrangement on the body, and the arrival times of the sound signals at the individual receivers are measured and compared with one another. Given n sound receivers in an open arrangement, the result for the sound source (generator) is a spatial resolution of 2n-2 volumetric regions, while for a closed arrangement there are 2n volumetric regions. Given the combination of a plurality of open or a plurality of closed arrangements of sound receivers one under another in each case, or given the combination of open and closed arrangements, the result is a spatial resolution which is a product of the individual resolutions. Additional signal parameters, e.g. energy, maximum amplitude, rise time, frequency content, can be measured for the purpose of fault evaluation and specified with reference to the source location.

Title: Process for rounding the intermediary oxide between the polysilicon plane and metal conductor track plane when fabricating integrated n-type channel MOS field-effect transistors
Inventor: WICHMANN BERNHARD DIPL PHYS
IPC: H01L21/3105
Filed: 1981-08-25
Abstract: The invention relates to a process for rounding the intermediary oxide (4) between the polysilicon plane (3) and metal conductor track plane when fabricating integrated n-type channel MOS field-effect transistors. In the process, the planarisation of the intermediary oxide layer having a phosphorus content of </= 5% by weight is carried out at temperatures </= 900 DEG C in conjunction with the densification in a humid oxygen atmosphere, a reoxidation layer (5) being formed simultaneously on the substrate (1, 2, 3). After the phototechnique (7) for the contact holes (6) has been applied, a second planarisation step can then be carried out, in which the phosphorus covering (24) for the contact holes (6) takes place. The phosphor-glass layer (14, 24) is removed before the metal conductor track plane is generated. <IMAGE>

Title: Control unit having an input keyboard
Inventor: KRAEMER HERBERT
IPC: H01H13/70
Filed: 1981-09-04
Abstract: A printed circuit board (3) has a carrier for a keyboard which is constructed from individual keys (4) is intended, according to the invention, to be installed in the unit housing (1, 2) such that the side of the printed circuit board carrying the key switch bodies (4) and the components (5) faces the base surface of the housing, while the solder side of the printed circuit board in contrast faces the control surface of the unit, which is formed by the housing cover (lid) (2). In order to keep small the distance between the control surface of the unit and the printed circuit board which is arranged parallel thereto, the structural height above the base surface in the interior of the unit can be made optimally usable by the switch bodies (4) and components (5) which are arranged on the printed circuit board. In this case, a virtually flat course, without any troughs, is produced for a sealing intermediate layer (6) which is arranged between the printed circuit board and the base surface of the unit and is supported by the solder side of the printed circuit board. <IMAGE>

Title: Regenerator for digital signals
Inventor: FAHRENDHOLZ JOACHIM ING GRAD
IPC: H04L25/24
Filed: 1981-10-27
Abstract: A regenerator for digital signals consists in known fashion of an amplitude discriminator (1), a time discriminator (3) connected downstream and an addition stage (5) in front of the amplitude discriminator (2) which combines the input signal and a compensation signal. The novelty of a regenerator of this type lies in that the compensation signal  DELTA u'(t) is produced by forming the difference between the input signal uE(t) and a reference signal uR(t), renewed after each amplitude discrimination, in a second addition stage (6) decoupled in relation to the first addition stage. The second addition stage (6) is inserted between the input signal uE(t) and the reference signal uR(t) derived from the output of the amplitude discriminator (2). A switching element (4) is disposed between the two addition stages (5, 6) to suppress the differential signal  DELTA u(t) during the signal transitions of the input signal uE(t). The compensation signal  DELTA u'(t) thus obtained is added in the first addition stage (5) with the correct amplitude to the input signal uE(t). A regenerator of this type contains no frequency-dependent elements in its compensation and is thus easy to integrate. It is largely independent of the pulse shape, timing and also timing jitter. A receiving network connected upstream is not required for signals with little distortion. <IMAGE>

Title: Process for fixing pollutants, in particular heavy metals, in sewage sludges
Inventor: HERES HANS
IPC: C02F11/00
Filed: 1982-02-18
Abstract: The primary pollution load of domestic and industrial sewage sludge is demonstrated. Leaching of the pollutants from the sewage sludge is determined by elution trials. It is shown how by adding clay powder having a proportion of montmorillonite to the sewage sludge the leaching of pollutants can be substantially reduced by fixing the heavy metals, such as in particular cadmium, to clay minerals. The action of the clay minerals and in particular of the montmorillonite is explained in relation to their capacity to fix inorganic and organic compounds. In addition, a marked reduction of the odour pollution of sewage sludge during processing, transport and landfill is achieved.
