Abstract: The present invention provides a process for the production of hyaluronic acid (HA) derivatives cross-linked with another polymer, in particular multiple e.g. double cross-linked hyaluronic acid derivatives. The invention also provides novel cross-linked derivatives, products containing them and their uses in cosmetic, medical and pharmaceutical applications.

Abstract: The present invention relates to a process for the production of hyaluronic acid (HA) derivatives. In particular, the process relates to multiple cross-linked hyaluronic acid derivatives, to navel cross-linked derivatives so obtained, and to products containing them and their uses in cosmetic, medical and pharmaceutical applications.

Abstract: A moving-light indicia reader system including a conveyor 12 carrying parcel 14 bearing a destination address 20. A moving-light illumination source 24 defines a spot 30 that moves at the same speed as the conveyor 12 to assist the positioning of the parcel 14 on the conveyor 12. A scanner 36 and a computer memory 42 of a character recognition system 40 are operated so as to store an image of a region 50 defined-with respect to the moving spot 30 defined by the moving-light illumination source 24. A sensor assembly 32, including a height sensor and reflectivity sensor, is located toward the downstream end of the moving-light illumination source 24. The scanner 32 is focused in response to height data from the height sensor, and the gain of the scanner 32 is adjusted in response to reflectivity data from the reflectivity sensor, so that the scanner 32 generates a clear image of the top of the parcel 14 at the location of the spot 30 as the parcel 14 passes beneath the scanner 32.

Abstract: A cantilevered electrical light fixture (10) has a power supply line (30) running through it from a mounted end (17) to an internal connection zone (36) at a cantilevered end (18). A cover (52) closes the internal connection zone (36) and mounts a plug-half (40) and a switch (42), which are electrically connected to the power supply line (30). A light head (16) mounted to the cantilevered end (18) by a post (76) with a non-circular portion (78) and a threaded shank (80) has lamp wiring (110) connected to a plug-half (120) which releasably mates with the plug-half (40) mounted to the arm (12). A U-shaped bracket (116) mounts a socket (114) to a shell (84) of the light head (16) to bias the lamp bulb (154) against the shell (84).

Abstract: 6-[(Cyclic amino)alkylamino]-7,8,9,10-tetrahydro-1,2,4-triazolo[3,4-a]phthalazines are novel compounds prepared by the reaction of a 6-halo-7,8,9,10-tetrahydro-1,2,4-triazolo[3,4-a]phthalazine with an appropriate (cyclic amino)alkylamine. The compounds are useful as bronchodilators.

Abstract: Substituted tetrahydroimidazo[2,1-a]phthalazine compounds such as 6-methylamino-7,8,9,10-tetrahydroimidazo[2,1-a]phthalazine are prepared by reacting a 6-halo-7,8,9,10-tetrahydroimidazo[1,2-a]phthalazine with an appropriate amine. The compounds are useful as bronchodilators.

Abstract: Substituted tetrahydropyridazino[1,6-a]benzimidazole compounds such as 2-methylamino-6,7,8,9-tetrahydropyridazino[1,6-a]benzimidazole are prepared by reacting a 2-halo-6,7,8,9-tetrahydropyridazino[1,6-a]benzimidazole with an appropriate amine. The compounds are useful as bronchodilators.
