Abstract: The method of producing luminescent bacteria is based on the transfer of genetic information for biological luminescence to obligate chemolithoautotrophic nitrifying microorganisms. In particular, luciferase DNA or a luciferase-beta-galactosidase transcription fusion is transferred into ammonia-oxidizing bacteria with the aid of plasmid- or transposon vector systems. The bioluminescent nitrification microorganisms, particularly Nitrosomonas strains modified by genetic engineering, are used in order to identify specific inhibitors during nitrification processes, the viability of these microorganisms being determined by measuring the decrease in luminescence. A particularly important application is that inhibitors in a nitrifying biological sewage treatment plant can be detected in this manner.

Abstract: Flow controls that can be inserted in a liquid-supply line or in the accommodating bore of a plumbing fitting. The controls have an essentially cup-shaped mount with perforations through its bottom and a disk of resilient material fits into the perforations. At least the edge of the side of the disk facing the bottom of the cup has a conical bevel of 1.degree. to 5.degree. to the midplane of the disk and narrow ribs and/or sector-shaped webs that extend out essential radially at a prescribed angle around a prescribed circumferential angle.

Abstract: A centrifuge drum and a method of filling an automatically discharging centrifuge drum with a mixture of liquids that is to be separated. The mixture is introduced through an intake pipe and a header. The header's intake section communicates with a stack of disks through openings in the header's base. The base is provided with radial supply channels. Channels at the center of the stack divert the separated lighter liquid phase into a diversion chamber and channels at the periphery of the stack divert the separated heavier liquid phase into another diversion chamber. The drum is charged with an auxiliary liquid obtained from a lower section of the base up to a radially inward level that covers the intake openings into the supply channel in an upper section of the base of the foot. The mixture is then introduced at full power through both sections of the base.

Abstract: A reactor for corrosive and abrasive reaction mixtures having an upper setion and a conically tapered lower reaction section, with a screw mixer consisting of a jacketed band surrounding a conveyor screw, suspended fron the top of the reactor, and an inlet for solid reactants which leads directly into the vertical conveying device.

Abstract: The invention relates to pharmaceutical preparations having controlled release of active compound and to processes for their preparation, in particular for poorly soluble active compounds having problematic bioavailability.

Abstract: p-Haloalkoxyanilines are obtained from the corresponding nitrobenzenes by catalytic hydroxylation in the presence of an aqueous acidic reaction medium with the formation of a corresponding aminophenol and reaction of this aminophenol with a halogenated olefin in the presence of water and a catalytic amount of base.

Abstract: A method and system for controlling heating cables wherein a plurality of two-conductor heating cables are disposed in contact with heatable vessels to heat the vessels. Power lines having at least two conductors are connected to the heating cables through a plurality of first switches. Each first switch is responsive to a control signal for selectively connecting and disconnecting one heating cable to and from the power lines. Each of a plurality of remote terminals is connected to the two conductors of a heating cable and detects the temperature of the heatable vessel heated by the heating cable. At least one main controller for controlling a plurality of first switches is connected to two of the power line conductors. Temperature data relating to temperatures detected by the temperature sensors is transmitted from the remote terminals over the heating cables and the power lines by spread spectrum data transmission to the main controller.

Abstract: Adhesive tape for a bond which can be redetached by pulling, without residue and without damage, having a foam backing coated on one or both sides with a self-adhesive composition, characterized in thata) on at least one of the two sides of the foam backing there is applied a self-adhesive composition whose ratio of tear strength to stripping force (peel force) at a peel angle of less than 10.degree. to the bond surface is greater than 1.2:1,b) the foam backing is subjected to controlled pretreatment/damaging in such a way that the detachment force (stripping force) is lowered relative to an analogous self-adhesive tape with a foam backing which has not been correspondingly pretreated/damaged, andc) the foam backing does not have a tear strength which is sufficient for redetachment without residue or damage.

Abstract: A method and system for processing a digital image of an object comprises forming a single pixel image outline of the object in a digital image and producing a measure of the outline shape as a single number. In this way risk of spina bifida can be determined from an ultrasonic image of a fetal skull.

Abstract: The invention relates to a back projection module (1) for displaying an image on a large-area projection screen (2). An improved construction of the projection screen (2) and the supports holding it is proposed to obtain a substantially continuous large image by means of adjacent projection modules (1). The invention also relates to a suitable module housing permitting the arrangement of adjacent projections modules with a shallow depth. Further details concern the improvement in the quality of the optical image.

Abstract: The exhaust gas stream is passed through a bed of a granular adsorbent for separating noxious substances. The bed consists of the mixture of a granular high-carbon material and a granular inert material. The bulk density of the inert material is 0.8 to 3 times the bulk density of the carbonaceous material. Preferably, the content of the high-carbon material in the bed is 5 to 80 wt-%. The high-carbon material may for instance be activated carbon, activated coke or lignite coke. As inert material there may for instance be used siliceous rock, pumice, lava, slag, vitrification residues or fine gravel.
