  • Publication number: 20050235000
    Abstract: The invention relates to an AAA (Authentication, Authorization, Accounting) server system (RADSS) for managing a pool (A) of logical addresses (IP1, . . . , IPN) and a method for updating status information within the AAA server system (RADSS). Said AAA server system (RADSS) comprises several AAA servers (RAD1, RAD2, RAD3). Each of the AAA servers (RAD1, RAD2, RAD3) are assigned one or more discrete partial amounts (A1, A2, A3) of the address pool (A). Status information exchanged relating to address allocation affect the discrete partial amounts (A1, A2, A3) of addresses. The invention has the advantage of a low-complexity and efficient message exchange between the AAA servers (RAD1, RAD2, RAD3). An efficient allocation of resources to logical addresses is guaranteed as a result of changes to the assignment of partial amounts (A1, A2, A3) of logical addresses (IP1, . . . , IPN) in AAA servers (RAD1, RAD2, RAD3), according to need.

  • Patent number: 5879669
    Abstract: The aqueous hair fixing composition contains 0.1 to 30 percent by weight of at least one thickener, e.g. acrylic acid polymer; 0.1 to 25 percent by weight of a film-forming polymer ingredient which consists of vinyl acetate/crotonic acid copolymer, acrylic acid/acrylamide copolymer and/or methyl vinyl ether/maleic anhydride copolymer and 45 to 99.8 percent by weight water. This aqueous hair fixing composition necessarily contains no organic solvents, no cationic surfactants and no cationic polymers and a physiologically acceptable acid or base is added to it to adjust its pH so that the film-forming polymer ingredient is at least partially precipitated.

  • Patent number: 5833968
    Abstract: The aqueous hair fixing composition is in the form of a highly viscous sprayable gel and contains 0.1 to 50 percent by weight of one or more disaccharides or a mixture of 2 to 37 percent by weight of one or more disaccharides and 63 to 98 percent by weight of one or more oligosaccharides, 0.05 to 30 percent by weight of one or more cationic polymers, and 0.05 to 10 percent by weight of at least one thickener selected from the group consisting of honopolymers of acrylic acid, acrylic acid/acrylamides copolymers and sclerotium gum, The composition of the invention necessarily does hot contain monovalent aliphatic alcohols having 1 to 4 carbon atoms and no inorganic salts of alkali metals or inorganic salts of bivalent or trivalent metals. Either the composition is sprayed with the aid of a mechanical spray device or, alternatively, a gaseous propellant is included in it and the composition and propellant is included under pressure in a dispensing container.

  • Patent number: 5690924
    Abstract: The hair treatment composition is based on a polymer combination including (A) 0.01 to 40 percent by weight of a salt formed from a chitosan having a molecular weight of at least 100,000 g/mol and 2-pyrrolidon-5-carboxylic acid, and (B) 0.01 to 50 percent by weight of at least one synthetic, film-forming anionic or nonionic hair fixing polymer, or natural film-forming hair fixing polymer. This hair treatment composition provides an improved action in regard to combability, care sensitivity, load on the hair, brushability, hair feel, hair fixing action and residues left on the hair.

  • Patent number: 5512276
    Abstract: The aqueous, alcoholic or aqueous/alcoholic composition for fixing hair includes from 1.0 to 10 percent by weight of a sulfur-free lignin, which can be hydroxypropyl lignin, hydroxybutyl lignin, dihydroxypropyl lignin and/or mixtures thereof; from 1 to 15% by weight of a film-forming polymer; and a solvent including water, an alcohol having one to four carbon atoms and/or mixtures thereof. It can be in the form of an aerosol hair spray, a non-aerosol hair spray, a non-aerosol foam or a non-aerosol hair lacquer. The composition can also include 2 to 80 percent by weight of a propellant.

  • Patent number: 4337903
    Abstract: The method of and device for controlling the roll exchanging operation in an unrolling device includes the provision of a set of control numbers computed from the counted number of revolutions of the old roll and from the length of the withdrawn web prior to the initiation of the roll exchanging operation; the control numbers are computed from two intervals of the measured web length, from corresponding intervals of the counted number of revolutions, from the thickness of the web, from the feeding speed of the web, from the time constents of the control elements of the roll exchanging device, from the length of the adhesive leading edge of the new roll, from the desired length of the residual trailing end portion of the old web and from the diameter of the supporting central reel; computed control numbers are stored and compared in a comparator with the actual number of revolutions of the old roll whereby the coincidence of the actual number with the stored number generates in a control unit a control signal

  • Patent number: 4231872
    Abstract: An apparatus for the desalination of water using a mixed cation-anion exchange resin bed and comprising a cylindrical, pressure resistant tank, a disposable cartridge containing the resin and positioned in the tank and seals at the sides of the cartridge for preventing leakage around the bed; the cartridge is preferably made from a lightweight, inexpensive material such as a polyolefin plastic, i.e., polyethylene.
