Patent DE-3820009-A1 (DE)
Title: Stoppage monitor for a shaft
Inventor: BANNIER GEORG
IPC: G01P13/00
Filed: 1988-06-11
Abstract: The invention relates to a stoppage monitor for a shaft, in particular of a gear with a safety slipping clutch (friction safety clutch), having a shaft which is mounted in a housing and can be brought into rotary engagement with the shaft to be monitored. Provided coaxially with the shaft in the interior of the housing, which is filled with a highly viscous liquid, are annular discs which are arranged alternately in a fashion rotationally fixed relative to the housing and to the shaft and limited in a freely movable fashion in the axial direction accompanied by the formation of annular gaps located therebetween. The housing can be rotated about the shaft to a limited extent in both senses of rotation between stops against a spring bias, and provision is made of a limit switch which can be operated by the rotary movement and whose operating member cooperates with a notch (indentation) fixed to the housing. In order to simplify the construction, it is provided that the edges of the notch are dimensioned such that the restoring force of the limit switch which acts via the operating element continuously acts on the respective edge while supplying the spring bias. The torque for deflecting the housing can be produced at least partially by annular gaps, of wedge-shaped section, between the annular discs.

Patent DE-3916219-A1 (DE)
Inventor: EHWALD RUDOLF PROF DIPL BIOL D
IPC: B01J20/281
Filed: 1989-05-18
Abstract: The present invention relates to a device and a method for chromatographic separation with a chromatographic fixed bed as a dry packing in a closed column or as a dry layer on a foil or plate. The fixed bed has a high volume portion of gas- filled intra-particle and extra-capillary spaces and consists entirely or predominantly of vesicular or cellular carriers. The intrinsically absorbent fixed bed is - regardless of the high capacity for absorbing liquids - volume-stable at the moistening front. It makes possible a chromatographic method whereby low molecular weight substances can be separated from macromolecules by exclusion chromatography, elution of the macromolecules in a concentrated form being possible at the same time. The sorbent is best prepared by freeze-drying.

IPC: B42D25/00
Filed: 1989-12-01
Abstract: Multi-layered solid plastic identity card comprising a laminate of different plastic layers which is particularly resistant to environmental influences and effects of daily use and has high durability. The use of plastics which are stable at high temperatures, such as PC (polycarbonate), for the card core (3) and the outer sheets (1) ensures the dimensional and temperature stability even under extreme environmental conditions and the use of intermediate layers (2) of a thermoplastic elastomer such as TPU (thermoplastic polyurethane) minimises the risk of the card breaking, since these layers absorb stresses and shearing forces and make the card flexible. <IMAGE>
Patent DE-3941572-A1 (DE)
Inventor: LANG GUENTHER DR
IPC: A61K8/02
Filed: 1989-12-16
Abstract: The invention concerns a mixture of solvents containing no liquefied propellants and sprayable by means of compressed gases or mechanically driven sprays having a water content of 5 to 30 % wt together with 0.5 to 45 % wt lower alkanes and 50 to 94.5 % wt lower alcohols in which the ratio of the proportions by weight of water to alkanes is from 0.1:1 to 10:1. The invention also concerns cosmetic agents for treating the skin and hair which contain this solvent mixture.

Title: Tapping system for metallurgical vessel - has tubular element joining the vessel bottom to reception container top to facilitate tilting
Inventor: TODZY HUGO
IPC: F27D3/15
Filed: 1990-03-20
Abstract: Tapping steel from metallurgical vessel has the novelty that before tapping, the melting unit is tilted to 6-10 deg.  and subsequently the melt is discharged through a tapping opening.
