Patent DE-4330975-A1 (DE)
Title: Method for fitting a power component on a printed circuit board
Inventor: RAU MARTIN ING GRAD
IPC: H05K7/20
Filed: 1993-09-13
Abstract: In the case of power components (10) the thermally conductive metal layer (14) is not electrically floating, so that a ceramic layer (13), for example, is arranged on the power component for electrical insulation. Both the ceramic layer (13) and the metal layer (14) are produced, according to the invention, using the so-called plasma spraying method, or a similar method. In order to mount the power component (10) on the printed circuit board (11), a solder paste (15) is applied onto the printed circuit board (11) and the component is mounted using so-called reflow soldering. The power component (10) is thus mounted in a simple and cost-effective manner, both in an electrically insulated manner and in a highly thermally conductive manner on the printed circuit board (11), without any additional parts. <IMAGE>

Patent DE-4333152-A1 (DE)
Title: Selective dissociation of chemical cpds. esp. for sepn. or purificn. - by stimulation in vibrational or rotational-vibrational band e.g. with UV, visible or IR light, esp. laser light
Inventor: HORNBURGER HELMUT
IPC: C07B61/00
Filed: 1993-09-29
Abstract: Selective dissociation of chemical cpds. (I) is effected by stimulation in a vibrational or rotational-vibrational band of (I). Pref., mode-selective stimulation is carried out with an energy below the dissociation energy, so that dissociation occurs by the tunnel effect. (I) are stimulated in the gas phase. Stimulation is carried out by absorption of electromagnetic waves, esp. UV, visible or IR light, pref. with a tunable laser, esp. in modes with non-dissociative potential. In particular, out-of-plane oscillations are used with (hetero)aromatic cpds. In sepn., the prods. (II) and (I) are sepd. with magnetic or electric fields or by chemical reactions. Stimulation pref. is carried out in a vibration band of selective rotational state (rovibronic), pref. various electron states with different vibronic selectivity. Selective dissociation is carried out by the different specificity (symmetry) of the modes w.r.t. the transition to sec. electron states with different symmetry and spin selection principles. USE/ADVANTAGE - Dissociation is used for sepn. or purificn. (claimed). Cpds. with a high deg. of purity can be obtd. at relatively low cost.

Inventor: OTT PETER DR
IPC: C02F3/10
Filed: 1994-03-19
Abstract: A process and device are disclosed for the simultaneous biological elimination of phosphorus and nitrogen from waste water. The object of the invention is to increase the biological elimination rates for P and N compounds, even at low temperatures. Smaller reactor volumes are to be obtained by shorter retention times, as well as more reactions per unit of time and space. A hydrolising and acidifying stage (1) designed as a floating bed filter with a waste water inlet is subdivided into an anoxic zone (1a) and into an anaerobic zone (1b), contains floating carrier material and is provided with an aerating device. A downstream nitrification and denitrification stage (2) is subdivided into an aerated fluidised bed zone, a zone that may be selectively operated as an aerated fluidised bed zone or as a non-aerated floating bed zone, as well as into a non-aerated floating bed zone, and contains less than 80 % by volume of a floating carrier material. The retention time in stage (1) lasts more than 1.5 hours, air being rapidly blown in and the carrier material being swirled every 6 hours. In stage (2) the mixture of waste water and activated sludge is treated in at least one aerated and one non-aerated zone. The waste water is recirculated through stages (1) and (2), as well as through the final sedimentation device (3). The growth carriers are retained in their corresponding stages (1) and (2). The invention may in particular be applied in small and medium waste water purification plants for communal and industrial waste water, as well as in purification plants for waste water from the production of foodstuffs and stimulants.

Title: Process and device for operating a windscreen wiper
Inventor: WINNER HERMANN
IPC: B60S1/08
Filed: 1988-12-31
Abstract: In a process for operating a windscreen wiper, a beam of radiation (11) emitted by a radiation source (10) is input at a definite angle (16) into a windscreen (13) the outer surface (14) of which is to be cleaned by a windscreen wiper. The angle (16) is closen so that the beam (11) is totally reflected at the outer (14) and inner (19) surfaces of the windscreen, from which it emerges at a particular position and is directed to a radiation receiver (21). When the outer surface (14) of the windscreen is wetted with drops of water (22-25), a loss radiation (28, 29) is output. This results in a reduction of the signal (43) emitted by the radiation receiver (21). If the signal (43) falls below a threshold by a predetermined amount, a cleaning process of the windscreen wiper is initiated. The threshold is established in function of the peak value of the signal (43). The measured peak value is stored, the input time being appreciably shorter than the duration of storage.
