Title: Prodn. of screen polishing discs - by loading radial mould recesses with impregnated foam polishing segments, introducing resin mix, rotating mould and heating it to cure mix
Inventor: KNIEF WALTER
IPC: C08J5/14
Filed: 1990-10-13
Abstract: A disc for polishing or grinding screens is produced with an elastomer supporting plate and a polishing/grinding coating in segments made of plastics and foam in particular, the segments being arranged radially and sepd. by being in radial grooves. The segments are set in the lower mould tool of a revolving device, which is closed and the two parts of the mould are then heated; the revolving device is rotated at at least 300 rpm; a mix of (pref.) polyurethane elastomer is mixed with cross-linking agent and introduced as quickly as possible through the inlet of the rotating device so that it is there distributed centrifugally into the recesses in the top mould tool whilst at the same time being cured. The mix is pref.  made from 1,5-naphthylenediisocyanate and a polyesterpolyol, with butanediol-1,4 cross-linking agent. ADVANTAGE - The method produces a uniform and durable bond between the polishing disc and supporting plate. Its segments have rounded edges and corners. The disc formed has uniform thickness and is suitably flexible; this reduced thickness minimises  internal heat generation and it loses frictional heat well. The process uses a hard type polyurethane with high Youngs Modulus.

Patent DE-4102862-A1 (DE)
Inventor: MERZ GERHARD DR ING
IPC: C10G9/12
Filed: 1991-01-31
Abstract: A process for decoking pyrolysis furnaces for the thermal cracking of hydrocarbons is described. A decoking gas, in particular a steam/air mixture, is passed through the coked plant sections. This gives a decoking off-gas, which sometimes contains large quantities of carbon monoxide and therefore cannot readily be discharged into the environment. It is therefore proposed to subject the decoking off-gas to catalytic afterburning and to release the off-gas thus purified into the atmosphere.

Patent DE-4132894-A1 (DE)
Inventor: FUNK GUIDO DR
IPC: C08F10/02
Filed: 1991-10-04
Abstract: In a new process for the preparation of a supported catalyst for the polymerisation of  alpha -olefins, first a support gel (1) is prepared by introducing a sodium water glass or potassium water glass solution into a swirling stream of an aqueous mineral acid optionally containing aluminium ions longitudinally and tangentially to the stream, spraying the resultant silicic acid hydrosol in drop form into a gaseous medium, and allowing it to solidify to form a hydrogel, and freeing the resultant hydrogel, without prior ageing, from salts by washing and optionally from some of the water by extraction with alcohols and/or ketones, and then drying the hydrogel. This gives the support gel (1), which is ground and fractionated according to particle size. In a second process step, the support gel (1) is charged with chromium trioxide or with a chromium compound which can be converted into chromium trioxide, after which the resultant chromium-containing support gel (2) is heated at from 400 to 1100 DEG C for from 10 to 1000 minutes in an anhydrous gas stream containing oxygen in a concentration greater than 10% by volume. It is essential for the process according to the invention that the drying of the hydrogel to form the support gel (1) takes place in a high-speed drier within a maximum time of 300 seconds at an inlet temperature of from 200 to 600 DEG C. The supported catalyst prepared in this way gives homopolymers and copolymers of ethylene having excellent low-temperature toughness.
