Inventor: ROINER FRANZ PROF
IPC: A61L2/025
Filed: 1992-08-13
Abstract: Microorganisms are destroyed in a gaseous, liq. and/or pasty medium by treating the medium with ultrasound.     Pref. treatment is for not above 60 secs., at a frequency of not less than 18 kHz (not less than 20 kHz), a capacity of not less than 2000 watts, and a constant or variable temp. of 0-100 deg.C., opt. using an agitated medium. Treatment may be first at a raised temp. and then at a reduced temp., or vice versa, e.g. it may be raised from a starting temp. of not below 58 deg.C. or lowered from a starting temp. of not above 15 deg.C. and may be altered stepwise. Ultrasound treatment may be repeated, and before repitition the temp. of the medium is brought to the initial value. The viscosity of the medium may be reduced. The pH is not 7, pref. below 6.8 or above 7.1. Before, during or after the ultrasound treatment, the medium may be irradiated with micro-waves. The ultrasound intensity may be varied, and is pref. raised during treatment. The intensity is varied in pulses and/or is briefly interrupted, and is pref. accompanised by micro-wave treatment for not above 3 secs.. Several ultrasound sources may be used, in sequence and/or in parallel, with differing capacities, and vertical and/or transverse and/or sloping w.r.t. the medium. The intensity of treatment is controlled by the distance of the ultrasound source from the medium, by contact of the source with medium and/or by the depth of dipping of the source into the medium. In flowing gaseous media, the amt. of dry matter and/or moisture is varied. The temp., pH value, viscosity, dry matter content, moisture content, flow rate and/or degree of agitation of the medium may be varied during, before or after the ultrasound treatment. Coarse and/or fine dispersed substances may be fed into the ultrasound treatment space and/or form additionally in the substrate to be treated, thus accelerating the destruction of microoganisms present and/or the homogenisation. The density of the medium is at least 1.01 g/cc, and its acitivity or water activity is not above 0.995.

Patent DE-4329982-A1 (DE)
Title: Electrodynamic sound transducer
Inventor: SCHUTTER ERNST
IPC: H04R7/12
Filed: 1993-09-04
Abstract: An electrodynamic transducer comprises a diaphragm which is essentially divided into two differently contoured parts. This includes firstly an acoustically effective central part and a ring part adjoining the former at its edge, which is used for the elastic suspension of the entire diaphragm. Between the central ring part, there is narrow coil seat for a wire coil of the transducer. To develop a space-saving and, nevertheless, electrodynamically sensitive sound transducer, it is proposed to arrange the ring part not radially outside the central part of the diaphragm but to displace it inwards. The arc-shaped ring part is then located in the protection of the axial curvature of the central part. The ring part can therefore have the ring width required for ideal elastic suspension without this having a disadvantageous effect on the external dimension of the transducer.

Title: Electronic apparatus
Inventor: ATARASHI TAKAYUKI
IPC: H01L23/467
Filed: 1993-10-06
Abstract: An electronic apparatus which has a plurality of semi-conductor components (121) which produce heat while they are operating. A cooling element (22) having a plurality of cooling ribs which are, for example, in the form of surfaces, are provided on each semiconductor component. Nozzles (23) are assigned to the cooling elements and feed a cooling fluid such as air to said cooling elements. The direction (27) of the flow and the removal of the cooling fluid are the same in all the cooling elements. The width (W) of the nozzle, measured in the direction of the flow determined by the cooling element, and the removal means of the cooling fluid (x direction) are smaller than the width (L) of the associated cooling element. The width of the nozzle measured in the direction at right angles to the x-direction is not less than the width of the associated cooling element. The space between adjacent nozzles represents a removal channel having a large cross-section, which has a reduced flow cross-section for the heated cooling medium which is to be carried away. In a cooling device according to the invention, the cooling fluid is predominantely passed into the central region of the cooling element where the cooling requirement is at its greatest. Such flow guidance is achieved either by slots constructed in the cooling ribs or by flow guidance devices (202, 202a) which extend into the cooling element. <IMAGE>
