Patent DE-3720238-A1 (DE)
Inventor: MENGERINGHAUSEN MAX DR ING DR
IPC: E04F15/024
Filed: 1987-06-19
Abstract: In previous composite building slabs for sectional false floors, which are supported at their four corners and consist of an upwardly open trough produced from tension-proof material and of a filling of compression-proof material, e.g. anhydrite, a greater deflection is produced, under load, at the edge of the slab than in the centre of the slab, which is undesirable. In order substantially to even out the load-bearing capacity and security of composite building slabs of the above type against breaking at the edge of and in the centre of the slab, provision is made on the side walls (6g) of the trough (3g) for a reinforcement which is virtually at the height of the slab and is non-positively connected to the base (5) of the trough. In addition or alternatively to this, it is also possible to increase at least twofold the density and strength of the filling (2) in the edge region of the composite building slab (10g) relative to the remaining region towards the centre of the slab.

Title: Container with sight-glass
Inventor: BERWALD ERNST
IPC: B01J19/00
Filed: 1987-07-17
Abstract: The arrangement of a sight-glass (2) in the wall (1) of a container, which serves to take up reactive or flammable liquids or liquids otherwise damaging to health, represents a potential source of danger in the case of a glass breakage connected with an uncontrolled emergence of liquid. For this purpose, the sight-glass is covered in a sealing fashion with an outer cap. In the sight-glass arrangement according to the invention, the sight-glass (2) is received in a fully protected manner in a recess in a receiving body welded to the wall (1) of the container and is retained in this recess by means of a holding body. A threaded pipe element (16) is welded to the holding body, and carries on its end face a closure cap (17). By means of an axially extending groove (20) which is recessed in the outer surface of the threaded pipe element (16) and dimensioned to be longer than the outer thread serving to screw on the closure cap (17), a negligible emergence of liquid is allowed by a slight loosening of the closure gap (17) if the glass is broken, this indicating the defective sight-glass (2). <IMAGE>

Patent DE-3835827-A1 (DE)
Title: Method for reprocessing waste material
Inventor: BETZ MONIKA DIPL BIOL DR RER N
IPC: C10B47/24
Filed: 1988-10-21
Abstract: In the reprocessing of waste material, in particular plastic wastes, by pyrolysis, pyrolysis gases containing pollutants are formed. To reduce the formation of pollutants, the pyrolysis is carried out in the presence of basic additive material. Since the fully reacted additive material increases the pyrolysis residue, it is desirable to monitor the metering of the additive material. In the parent patent application P 3817437.5-24, it is indicated how the pH value can be measured in the low-boiling pyrolysis oil precipitated in a cooling stage and how the metering of the additive material is influenced as a function of the measured pH value. In variation of the teaching of the parent patent application P 3817437.5-24, it is proposed for the measurement of the pH value to mix a part quantity of the low-boiling pyrolysis oil only with water, to separate the water from this pyrolysis oil/water mixture, to subject the water to the measurement of the pH value and automatically to influence the metering of the additive material as a function of the measured pH value. In this way, a simplification as compared with the teaching of the parent patent application is obtained, according to which the bulk quantity of the pyrolysis oil is mixed with water, which contains a solubiliser, and then subjected to the measurement of the pH value.
