The process provides for the firing in a furnace of ceramic bodies and their coating in an incandescent state on one face with dry granular or powdered glaze when all firing reactions of the ceramic bodies have substantially reached completion; a subsequent thermal treatment fires the glaze and gradually cools the tile. The apparatus for carrying out the process provides for a furnace for firing c...

In a flexible multi-chamber bag for the sterilisation, storage and mixing of mixed infusion solutions, having a bag arrangement formed from film sheets (11, 12), a closure apparatus (20) which can be opened from outside serves to subdivide the bag into chambers, this closure apparatus consisting of a core rod (25) and a rod-shaped plug-on part (27) which clamps around the latter in the manner of a...

A process for prepg. monolitic catalyst for purifying exhaust gases comprises (i) mixing at least one Pt family compd. selected from a gp. of Pt, Pd and Rh with activated alumina, (ii) fixing Pt family compd. to activated alumina by calcinating at 200-900 deg.C or redn., (iii) dispersing above products and cerium hydroxide powder (5-100 g/ L amts. as CeO2, 0.1-0.8 micron of primary particle size) ...

An appts. controls the supply of air to a burner used to recombust diesel particulates trapped in a ceramic filter. The regenerator includes an exhaust bypass line that bypasses the filter. An air supply line leads to a burner associated with the filter. A flow control valve adjusts the cross-sectional area for the air flow in the air supply line and a relief valve maintains a constant differen...

A high-frequency capacitive heating electrode device comprises a cap-shaped electrode (12), a flexible support (11) for supporting the electrode (12) with one end thereof capped with the electrode (12), a flexible polymer film (14) which surrounds the electrode and forms a gastight space (13) between the support (11) and the flexible polymer film (14), and passages (15,16) for respectively introdu...

Novel spiro-oxathiolane/quinuclidine compounds correspond with the schematic structural formula (I) and geometrical isomers, enantiomers, diastereoisomers, racemates and acid addition salts thereof, wherein one of Y and Z is O and the other is S (=O)n; n is 0, 1 or 2; R min and R sec are each selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, hydroxyalkyl, aminoalkyl...

The invention relates to an arrangement 4 for fastening one end of a tape measure 1 in an elongate measurement object, in particular an arrangement for a tape measure for laying a felled tree off into log lengths. The arrangement comprises a body 6 with a spike 19 which can be rotated about an articulation 16 in the body, between a first position, in which the spike is directed essentially at righ...

The tube has an oxygen barrier film. The clamping rinq comprises two parts which are brought together by tightening the nuts and bolts that pass through holes in the flanges. Adjacent to flanges diverge and when the nuts and bolts are tightened, they deform to touch each other. The dia. of the coupling rinq is then less than the outer dia. of the tube. USE/ADVANTAGE - Coupling to polyethylene tube...

Three electromagnetic beams (33,34,35) are created with pedetermined direction and position in a room (22). A receiver/ transmitter (13,14,15) for oscillation energy is positioned in each of electromagnetic beams. At least two transmitters/receivers (16,17) for oscillation energy are The delay time interval for oscillation energy between each of transmitters/receivers on the feed beam and each of ...

The elastic band used (2) is made of non-conductive material. It encompasses two separate conductors. Holes (4) are made along the band which, when leakage occurs, qives water access to the conductors. As a result the conductance and capacitance increases, and can be indicated with the aid of a corresp. circuit.

In the decontamination of pipelines and water chambers of a steam generator in a pressurized-water reactor installation, it must be possible for the pipelines to be sealed. It is possible to seal pipelines with an inflatable sealing plug placed in the pipeline. In order to be capable of determining whether a sealing arrangement 1 in the pipeline 2 of the steam generator is correctly positioned whe...

The free end of the suspension device (1), i.e. its straight threaded part (3), inserts into a building component.
