Patent DE-4129321-A1 (DE)
Inventor: WITT SANDRA DR
IPC: B01D5/00
Filed: 1991-09-04
Abstract: A laboratory appliance for carrying out chemical reactions, in particular for analytical applications, has a flask (1) for the used substance surmounted by a reflux condenser (2). A funnel (7) whose neck end (10) is laterally guided towards the  inner wall (11) is inserted in the condenser. In addition, a dispenser automatically adds liquids into the flask (1) and a micro-wave oven heats the material contained in the flask (1). The neck end (10) of the funnel (7) extends so much downwards that the inner wall located below the neck end (10), in the area of liquid discharge, forms a smooth surface with no projections nor recesses. The advantages of an automated micro-wave laboratory system can thus be used for the analysis of a large number of samples, at the same time as the required reliability and precision of the results of the analysis are ensured.

Title: Production of FRP with precise fibre content in thermoplastics
Inventor: JORDE JOACHIM DIPL ING
IPC: B29B7/90
Filed: 1993-01-08
Abstract: FRP Materials are produced with a thermoplastic matrix and fibre reinforcement layers by mixing the materials with the matrix in a fused state. The fibres are applied to a film of fused matrix so that the required ratio of fibre to matrix is produced.Typically, the thermoplastic is fed (14) to the extruder (1) and there fused; the melt leaves (2) from a flat sheet nozzle (2a) in the form of a thin film (15) which falls (16) down vertically. Fibre material (6) is fed (5) directly on to the hot melt film (15) and both materials move to the mixer (7). The fibre feed is adjusted to the size of the film (15). The required fibre content is thus obtd.. The mixt. drops into the mixer (8) where a Z-kneading member (9) is revolving. The final mix is discharged from the nozzle (11a) for further processing while still hot. The overall process disperses the fibres into the polymer very rapidly.

Title: Steam generator
Inventor: THOMAS VOLKMAR DIPL ING
IPC: F22B1/28
Filed: 1993-02-13
Abstract: The invention relates to a steam generator with a distributor pipe arranged in a steam-generating space and having discharge openings.
