In a process for reclaiming (recycling) polystyrene-based plastic waste, the plastic waste is converted into a solution by treatment with a solvent. Bulky waste can thereby be converted into a space- saving form. The resultant solution has adhesive properties and can be used as a universal adhesive. Removal of the solvent from the solution allows the plastic material to be recovered in compact for...

Under certain operating conditions of diesel engines, diesel soot filters, which normally filter efficiently and consist of known foam ceramics, still show only a very low degree of particle separation or none at all, especially in the case of high exhaust gas temperatures and exhaust velocities, that is to say above all when the diesel engines run under full load. Foam ceramics, produced by ...

The invention relates to a sweetener having improved sucrose-like taste containing a) at least one synthetic sweetener and b) at least one aroma-free concentrated fruit preparation having a dry matter content of 60 to 80 DEG Brix, and to a dried product prepared therefrom and a process for its preparation. Such a sweetener and dried product are suitable both domestically and in industrial food ma...

The invention relates to macroporous polymeric membranes, their preparation and their use for polymer separation. The membranes consist of a cross-linked copolymer on the basis of one or more monovinylic monomers and one or more cross-linking agents and has a globular microstructure whereby the globular structures have a size of 0,05 to 0,5 mu m and are mutually interconnected by covalent bonds, ...

A hydraulic cement is formed from a Class C fly ash and an alkali metal activator. Mortar and concrete compositions can be prepared with this hydraulic cement. The cement is particularly useful in producing mortar and concrete compositions that achieve high strengths in a short time.

The invention relates to new 1,7-annelated esters and amides of indolecarboxylic acids having general formula 2, wherein the symbols have the meanings given in the specification. The compounds and their salts are very strong and selective antagonists of "neuronal" 5-hydroxytryptamine (5-HT) receptors, and can be used for the treatment of symptoms which are caused by over-stimulation of the...

Procedure for the sterilizing of medical equipment by means of an apparatus which comprises a sealable rinse chamber 2 in which nozzles 5 for spraying the sterilizing liquid are arranged so that they are directed towards the object to be sterilized. The object is placed on a rotary table 14 within the rinse chamber 2,the said table 14 being rotated about a mainly vertical shaft 15. A partial vacuu...

The frame fastener (2) is U-shaped with an outwardly bent support foot (12) at one end. The foot is enclosed by heel components (21) which are downwardly directed from the fastener main body, and has a hole (13) for a fixture screw. A reinforcement is formed as a bulb (14) between the fastener main body and the support foot, and can even serve as a control component for the lower end of the fasten...

A test object (21) and the master meter (20) are placed in an air channel to a fan unit, and are connected to an instrument (24) which compares the output signals from both of them, indicating any difference which may arise. Components (10, 11, 17, 18) are provided for fixing the object in the air channel which (11) is divided into at least three parts (5), and axialy displaceable units (15-18) pe...
