En eller flere styringsledninger (20) strekker seg fra	foringsanordningene (18), langs ut siden av foringen til ett eller flere koplingsstykker (24) som tilveiebringer forbindelsespunkter på innsiden av foringen. Det ene eller flere av koplingsstykkene (24) kan omfatte elektriske koplingsstykker (f.eks. direktekontakt koplingsstykker), induktive koplingsstykker (f.eks. induktive koplinger), optiske koplingsstykker (f.eks. fiberoptiske koplingsstykker) og hydrauliske koplingsstykker. Styringsledningen eller styringsledningene (20) kan være elektriske ledninger, fiberoptiske ledninger eller hydrauliske ledninger. Nedihullstrengen kan også brukes med en sementbeskytter (100) under sementeringsoperasjonen for å beskytte både innsiden av foringen så vel som det ene eller flerekoplingsstykker (24) som er forbundet med foringen. Sementbeskytteren (100) omfatter en hylse (110) som isolerer sement fra innsiden av foringen under en sementeringsoperasjon, slik at en foringskrapeplugg ikke behøves.

Inventor: GOLUBKOV IGOR
IPC: C07C1/24
Filed: 2006-05-23
Abstract: En fremgangsmåte som kan brukes ved fermentering av karbohydratsubstrater av planteopprinnelse for å fremstille C1-C5-alkoholer, og for syntese av høyere alkoholer, og andre oksygeninneholdende forbindelser. Siden C6 og høyere alkoholer ikke er oppnåelige ved en direkte biokjemisk rute, er det foreslått å syntetisere disse ved bruk av kjente kjemiske reaksjoner, hvori råmaterialet for syntesen er biogass og lavere C2-C5-alkoholer oppnådd ved den oppfinneriske fremgangsmåten hvori aminosyrene laucin, isolaucin og valin, eller en blanding derav, eventuelt fått fra gjærautolysatet, brukes som en biokatalysator ved fermenteringstrinnet. Det er også foreslått å bruke avfallsstoffer av C2-C5-alkoholproduksjon for å oppnå biogass. Fremgangsmåten tilbyr en løsning på følgende problemer: å betraktelig øke utbyttet av C2-C5-alkoholer ved fermentering av karbohydratsubstratet; å øke med 1,5-2 ganger produktiviteten av fermenteringen uttrykt ved C2-C5-alkoholproduksjon; og gjøre nytte av proteininneholdende avfallsstoffer for C2-C5-alkoholproduksjon, for å oppnå høyest effektivitet av biomassenytte ved produksjon av høyere oksygeninneholdende forbindelser og hydrokarboner.

IPC: B22D11/06
Filed: 2008-10-16
Abstract: A twin-belt casting machine for casting metal strip. The machine is provided with a casting cavity which includes an upstream fixed casting region, in which the belts are in fixed convergent paths in contact with the cast slab, and an adjacent downstream portion in which the belts are adjustable between alignment with the fixed convergent paths and non-alignment therewith (being less convergent or divergent). When the adjustable portions of the paths are moved outwardly relative to the fixed convergent paths, the belts separate from the cast slab at differing predetermined points within the casting cavity. By adjusting the downstream portion of the casting cavity in this manner, the casting machine can operate at essentially constant throughput for a wide range of alloys while ensuring that the cast slab exiting the caster has a temperature within a predetermined range suitable for further rolling to produce sheet product.
