Filed: 1993-12-17
Abstract: Ny katalysatorbærer og en fremgangsmåte for fremstilling av denne, karakterisert ved tilstedeværelse av valgte mengder av en hydrokarbonløselig magnesiumholdig forbindelse påført på bæreren sammen med løsningsmiddel, hvor det oppnås en over- flate som er jevnt og praktisk talt kon- tinuerlig fuktet med den solvatiserte magnesiumforbindelse i en tilstand av begynnende utfelling, slik at det dannes en jevn og praktisk talt kontinuerlig fordeling av magnesiumforbindelsen på og konformt med bærermaterialet. Tørkepro- sessen under disse betingelser er effek- tiv med hensyn til å bibeholde i en høy grad materialets effektive spesifikke overflate og porevolum. Bæreren som inneholder det absorberte magnesium, blir deretter tørket på kontrollert måte inntil det er oppnådd betingelser med i det alt vesentlige begynnende fuktighet, hvilket gir en jevn romlig fordeling av stablet retikulært magnesiuminnhold på 1-5 molekylære monosjikt på bæreren. Det er beskrevet en representativ fremgangs- måte for polymerisering eller kopolyme- risering av olefiner som gir stereospe- sifikke polymerer som f.eks. propylen.

Title: Anordning for kjeler
Inventor: LOQVIST KAJ-RAGNAR
IPC: F23C7/06
Filed: 1996-09-30
Abstract: En anordning for en oljebrenner innbefatter et keramisk rør (1) hvori det er anordnet et kortere rør (61) slik at det dannes et rom mellom dem. Anordningen står fritt i forbrenn- ingsrommet til kjelen og er koaksialt anordnet relativt en oljebrenner (66) som er montert i kjelromveggen. Forbrenningsavgasser i blanding med frisk luft fra oljebrennerens vifte suges inn i rommet, som ender inne i det keramiske rør. Oljebrennerflammen i det indre rør (61) varmer opp det indre rør, som i sin tur vil varme opp den luft som suges inn gjennom rommet og representere sekundær-forbrenningsluft. Sporet har skruelinje- formede rygger som gir sekundærluften en kraftig rotasjon; en rotasjon som er motsatt rotasjonen til brennerens primærluft. Da sekundærluften er varm og roterer kraftig, vil sluttforbrenningen bli meget effektiv.

Date Nov. 28, 1996The present invention concerns a process for the preparation of 3-carboxy-4-hydroxybenzaldehydes and derivatives thereof from phenolic compounds carrying formyl and/or hydroxymethyl groups in the 2 and 4 positions. The invention also concerns the preparation of 4-hydroxybenzaldehydes from 3-carboxy-4-hydroxybenzaldehydes. More particularly, the invention concerns the preparation of 3-methoxy-4-hydroxybenzaldehyde and 3-ethoxy-4-hydroxybenzaldehyde, respectively known as "vanillin" and "ethylvanillin". The process for the preparation of 3-carboxy-4-hydroxybenzaldehyde is characterized in that the group in the 2 position in a phenolic compound carrying formyl and/or hydroxymethyl groups in the 2 and 4 positions is selectively oxidized to a carboxy group, and optionally a hydroxymethyl group in the 4 position is selectively oxidized to a formyl group. A successive decarboxylation step for a 3-carboxy-4-hydroxybenzaldehyde produces a 4-hydroxybenzaldehyde.

Abstract: A rolling door is provided with a flexible door panel which can be wound upon a winding shaft pivoted above the door opening and provided with a drive. On the bottom end of the door panel, a stop rail of length less than clear span between side sections limiting door opening, is provided at two ends with fastening for wires running over pulleys supported in a bottom region and bracing the door panel. In the side sections, slide-like blocks are guided vertically slidably, detachably connected to the ends of the stop rail by a retainer and provided with breakthroughs for the wires running from the pulleys in the bottom region to the stop rail. To restore the rolling door to operation simply and where possible even automatically after a crash, the retainer is constituted by locking devices which release the stop rail in the event of force acting thereon from the side and which, when the blocks are pressed on from above, again interlock the stop rail and blocks.
