  • Patent number: 7735264
    Abstract: A motor vehicle door has a door body formed from a door inner part and a door outer panel fastened thereto. The door body has a shaft opening for a window shaft located inside the door body, and a shaft reinforcement fastened to the door inner part. The reinforcement extends below the shaft opening and supports the door outer panel via a downwardly bent flange of the door outer panel. A window seal for the shaft opening is received in a fastening groove formed by an upright longitudinal web of the shaft reinforcement and the downwardly bent flange.

  • Publication number: 20070199248
    Abstract: A motor vehicle door with a door body is formed from a door inner part and a door outer panel fastened thereto. The door body has toward a top, a shaft opening for a window shaft located inside the door body, and a shaft reinforcement fastened to the door inner part and extends below the shaft opening and on which the door outer panel is supported with its upper flange which lies adjacent to the shaft opening and is bent off downwardly. A window seal is assigned to the shaft opening and is received in a fastening groove formed at least by a first upright longitudinal web of the shaft reinforcement. For production reasons, the downwardly bent-off flange is made as a free-standing wall connected firmly to the shaft reinforcement only with its lower end portion. The free-standing wall delimits the fastening groove laterally together with the longitudinal web.

  • Patent number: 4399212
    Abstract: The present invention relates to a method and to a processing band for processing a sheet or strip of photographic material (1) which has been image exposed and is brought into surface contact, in the presence of water, with a carrier (2) which is impregnated with the required processing chemicals. The photographic material (1) which has been image exposed is repeatedly moved along a closed path and brought into surface contact with the processing band (2) along a specified portion of said path in the presence of water, the processing band (2) having at least wo sections with different processing functions (A, B, C . . . ) arranged one behind the other, with which every portion of the photographic material (1) comes successively into contact.

  • Patent number: 4277247
    Abstract: A dyeing process for improving the levelness of cellulose dyeings with vat dyes or anionic dyes and for preventing creases in the dyed goods, wherein the process according to the invention comprises dyeing the cellulose fiber material in the presence of a polypropylene oxide adduct, or a salt thereof, which adduct contains carboxyl groups and has been prepared from (a) an aliphatic diol which has an average molecular weight of not more than 2,600, (b) an aliphatic dicarboxylic acid, or its anhydride, having 4 to 10 carbon atoms, (c) an adduct of propylene oxide with an aliphatic alcohol which is at least trihydric and has 3 to 10 carbon atoms and (d) a fatty acid having 8 to 22 carbon atoms.

  • Patent number: 4252534
    Abstract: A dyeing assistat containing at least(a) an alkylbenzene or tetrahydronaphthalene (tetralin) or a mixture thereof,(b) an anionic surfactant,(c) a non-aromatic and water-immiscible solvent and optionally also(d) a polar solvent and/or(e) a non-ionic surfactant; this dyeing assistant can be used to promote the migration of the dyes and thus to improve the levelness and dye yield when dyeing synthetic fibre material, preferably polyester, in particular in the temperature range from 80.degree. to 130.degree. C.

  • Patent number: 4066395
    Abstract: A process for dyeing or printing aromatic polyamide fibres with cationic dyes in aqueous medium, wherein the medium containsA. a carrier which contains no ketone-forming carbonyl groups, andB. an anionic assistant.The process of the invention is especially suitable to obtain wilt cationic dyes dyeings having a color yield of 2 to 10 times greater than that obtained by using the same dye liquor but without the addition of any anionic assistant.
