IPC: A61K31/4468
Filed: 2005-06-24
Abstract: Blanding for intranasal tilførsel av fentanyl eller et farmasøytisk akseptabelt salt av samme til et dyr, omfattende en vannbasert løsning av (i)	fentanyl eller et farmasøytisk akseptabelt salt av samme, og (i i) et farmasøytisk akseptabelt additiv valgt fra (a)	pektin, og (b)	en poloksamer og kitosan eller et salt eller derivat av samme, forutsatt at blandingen er hovedsakelig fri for divalente metallioner når blandingen omfatter et pektin, og som sammenliknet med en enkel vannbasert løsning av fentanyl administrert intranasalt ved samme dose, framskaffer en maksimal plasmakonsentrasjon av fentanyl (Cmax) fra 10 til 80% av det som oppnås ved bruk av en enkel vannbasert løsning av fentanyl administrert intranasalt ved en identisk fentanyldose.

Abstract: Method of producing an oblong shell member made of fiber composite material by means of vacuum infusion, where the fiber material is impregnated with liquid polymer. A mould is applied with a mould cavity, in which a fiber insertion (3) with a first lateral face (1) and a second lateral face (2) is placed, and where said fiber insertion includes a plurality of fiber layers and a distribution layer (4), said distribution layer allowing a higher rate of flow for the liquid polymer than the fiber layers. A semi-permeable membrane (5) is placed opposite the first lateral face (1) of the fiber insertion, said semi-permeable membrane being substantially permeable to gasses and substantially impermeable to liquid polymer and further communicating with a vacuum source The distribution layer (4) is placed inside the fiber insertion (3) with fiber layers on both sides and is interrupted by a zone (6) opposite the semi-permeable membrane (5) Liquid polymer is directed via inlet channels (7, 8) to the distribution layer (4), thus creating a flow front (9, 10) between the distribution layer (4) and the second lateral face (2), said flow front moving through the central zone (6) towards the semi-permeable membrane (5)

Abstract: Abrasion-resistant revolving worms for use in screw-type rotary pumps for silicaceous mortar etc. are produced by metallizing (flame or plasma gun) the surface in three stages with a nickel coating containing chromium, boron, silicon, iron, copper, molybdenum and tungsten. In the first stage, the revolving worm is heated to 160-200 degrees C and receives a primer of 50-100 mu. In the second state, a total layer of 0.3-2mm is applied in runs of 0.2-0.25mm at 1100-1250 degrees C. The third stage of 160-200 degrees C, attained by a cooling rate of 5-10 deg. C/min, covers the spraying of a 50-100 mu layer. Final cooling is at the max. rate of 5-10 deg. C/min.

Abstract: The invention concerns a cleaning and coagulating device for cleaning tools soiled with pigments, paints, coolants, abrasives, de-greasing agents or the like, and for separating the waste water thereby produced into clean water and contaminant residue. The device comprises a housing with a cleaning tank (3), an agitation device (4) fitted in the cleaning tank (3), a trap container (6) and a filter (8) mounted on the trap container (6) for filtering out residues from the waste water. This cleaning and coagulating device is characterised by the fact that the cleaning tank has a first side wall aligned roughly vertically relative to the top aperture (10), a second side wall facing and inclined towards the first, and third and fourth side walls (13, 14) adjacent to the first and second and facing and inclined towards one another. The particular shape of the cleaning tank (3) gives it a greater capacity and ensures especially favourable flow characteristics for creating turbulence in the water.
