Abstract: The use of zwitterionic compounds as mold release agents in thermoplastics is disclosed. Molding compositions having good release properties, preferably compositions containing polycarbonate resins are thus disclosed.

Abstract: A method of using oligocarbonates having terminal groups containing iodine to prepare molded articles (e.g., toys and medical equipment) having high X-ray contrast is described. The oligocarbonates contain more thaan one diol unit, and have a weight average molecular weight (Mw) of less than 3000.

Abstract: An illuminator, in particular for a signal lamp, having at least one LED which is mounted on an LED printed circuit board is provided which permits uncomplicated and flexible production. A base housing of the illuminator is produced from plastic. The base housing is penetrated by at least two contact elements.

Abstract: The invention relates to agents and processes for detecting bacteria of the genus Listeria, in particular L. monocytogenes. The agents according to the invention include primers whose sequence is selected from the iap gene of L. monocytogenes. In addition, the agents according to the invention include peptides whose sequence is selected from the p60 protein and which are suitable for producing specific antibodies for the immunological detection of L. monocytogenes.

Abstract: The invention relates to agents and methods for the immunological detection of bacteria of the genus Salmonella. The agents according to the invention include peptides whose sequence is selected from the PagC protein, and which are suitable for producing specific antibodies for the immunological detection of salmonellae.

Abstract: The invention relates to oligonucleotides which are suitable for use as nucleic acid probes or as primers for the detection of Enterobacteriaceae, in particular of pathogenic Enterobacteriaceae, such as, for example, Salmonella sp. The oligonucieotides according to the invention are selected from the salmolysin-like DNA region and possess a sequence according to one of the formulae IIIa to IIIh, or a corresponding complementary sequence:______________________________________ GAA TAT ATT GCG TTA GAT TAA T IIIa (SEQ ID NO:19) AAA CTG AAG CTA CAG GTG CC IIIb (SEQ ID NO:20) CTT AGC AAG CTA ATT ATA AGG IIIc (SEQ ID NO:21) GGC ACG GTT GGT GCG CAT TTG G IIId (SEQ ID NO:22) GCC ATA CGT GTG GCC ATG TGA IIIe (SEQ ID NO:23) GGC GTG TGG TCA GTA ACC TGA IIIf (SEQ ID NO:24) TTG CTG GCC AGC ACG ACA CG IIIg (SEQ ID NO:25) and GAA TCA TCA CCG CCC TGA AT IIIh (SEQ ID NO:25).

Abstract: A monitoring device having a switching mechanism to open or close electric circuits in case of overload which operates as a function of a current-detecting device includes a processor and setpoint memories for comparing and evaluating actual values. A device for detecting additional load operational errors, statistical operating data, and maintenance instructions from at least the load current over the lifetime of the device and providing a run display to display this data are consecutively integrated into the monitoring device. Furthermore, input keys are provided for setting desired parameters, which can be displayed in the run display.

Abstract: A process for the quantitative immunological determination of an enzyme in a liquid, comprises incubating anti-enzyme antibodies which are adsorbed on a water-insoluble carrier, with the sample solution containing the enzyme, whereby the enzyme bonds to the antibodies but retains a reproducible proportion of its activity in its complex with the antibodies; removing the sample solution; washing the antibody carrier, which is charged with enzyme; and determining the activity of the enzyme bonded to the antibodies.

Abstract: Samples of fine dusts in air or gases are collected for analysis and measurement by atomic absorption or atomic fluorescence by conducting the air or gases across a surface of a sample container and causing the dust to be deposited electrostatically on the said surface. The sample container is then heated to a temperature sufficient to vaporize the particles of dust, and the vaporized particles are then brought into the beam path of an atomic absorption or atomic fluorescence spectrometer.
