Growing of microorganisms takes place in a fermenter in which simultaneously products of metabolism are separated and withdrawn by microfiltration with the aid of a diaphragm filter, and a suspension of microorganisms is stirred in the fermenter in the region immediately surrounding the diaphragm filter.

In the case of a device for compensating for rotary shocks and having at least two inertia masses which are arranged coaxially with respect to one another and can be rotated in a limited manner with respect to one another against the influence of a damping device, in order to improve the matching of the damping capacity of the device to the respective application and hence in order to optimise the...

The present invention provides an absorbent structure comprising a moisture-impermeable backing, an absorbent batt superimposed thereon and a moisture-permeable cover covering at least the side opposite the backing sheet of the absorbent batt. The absorbent batt contains two reservoirs each formed by compression of the fibers in the reservoir zone. The first reservoir is open toward the cover and ...

PURPOSE:To dectease the element size as well as to facilitate an easy element design, by providing the lead wiring feqturing the same function detouring the element in the package for the element.

For joining molded parts having silicon carbide surfaces, the surfaces are first roughened to a depth of about 100-500 mu m by removal of the free silicon either by vaporization or by etching when treating silicon containing silicon carbide layers containing at least 15% weight of excessive silicon. In the alternative, when no excessive silicon is present, the roughening can be done by laser shot...

A cast self-supporting roller-shutter box (10) made of concrete with an essentially U-shaped cross-sectional profile is described, on the free legs of the U of which end-strip profiles (11, 12), preferably made of plastic, are arranged, which cover the front face of the free legs of the U and have a number of anchoring elements (13) as well as, projecting at least partially into the profile of the...

PURPOSE:To eliminate the uneven thickness of an adhesive layer and to reduce remarkably whirling of a disk by sticking two substrate on which a recording layer has been formed, by using an adhesive agent curable by ultraviolet rays in which a spacer member has been mixed. CONSTITUTION:When sticking transparent disks 1, 5 consisting of a resin substrate of PMMA, etc., on which recording layers 2, 4...

A circuit for converting interlaced video data to noninterlaced video data at 30 frames per second, real time video rate, where rows of successive lines of video data applied to a single frame memory (4) are provided having data control means including write-in (7) and read-out (8) means for initially sequentially loading each row of memory with lines of interlaced video data of the first frame se...

Air-drying compositions useful as industrial maintenance coatings are made from aqueous solutions, dispersions or micro-emulsions of the salted reaction products of fatty acids and epoxy-amine adducts plus metal driers.

A car receiver is proposed with a traffic broadcast decoder and a transmitter scanning device in which the received field strength of the traffic radio transmitter is checked following each traffic announcement and, if the received field strength is low, the receiver is tuned to a traffic broadcast transmitter with stronger incoming signals.

Reducing gases can be detected in a gas mixture to be investigated, particularly in air, with high sensitivity and precision by means of a gas detector. The gas detector comprises a gas sensor which is arranged within a measuring chamber. The temperature of the gas sensor can be continuously increased according to a predetermined pattern from a starting value to an upper threshold value and can be...

PURPOSE:To reduce the level fluctuation of the carrier chrominance signal by securing the voltage whose level changes according to the level of the burst signal given from the addition circuit.
