Abstract: A motor suspension for fans has an air grille with radially extending braces and grille rings that are positioned coaxially to each other and are connected to each other by the radially extending braces. For adapting the motor suspension to a vibration behavior of a fan, at least one of a feature selected from a number of the braces and a diameter of the braces is varied to effect a reduction of acoustic noises and/or natural resonances of the motor suspension. The number of the braces that are preferably made of metal is preferably unequal to the number of vanes of the fan.

Abstract: Disclosed is a method for improving efficacy of surfactants, prevention of lamellar mesophases, temperature stabilization of the single phase region and a method for reducing boundary surface tension in micro-emulsions containing silicone oils by means of additives and a surfactant/oil mixture. The above effects are achieved, whereby an additive of a block copolymer with a water-soluble block A and a block B which is either a polyalkylene oxide with at least 4 C atoms in the monomer component or a polydiene or a partially or completely hydrogenated polydiene or polyalkane, is added to the micro-emulsion.

Abstract: A fuselage structure comprises a plurality of elements that in longitudinal direction are interconnected by weld joints; a plurality of circumferential ribs that are connected to the plurality of elements and that extend so as to be substantially perpendicular in relation to the longitudinal direction of the elements; and a plurality of clips that are arranged between the elements and the ribs such that said clips do not cover the respective weld joints.

Abstract: A mixture comprising a component I comprising 80-20% by weight of a first surfactant component I1, which is an alkylpolyglucoside containing 1-2 glucoside moieties and a hydrocarbon moiety, especially an alkyl residue of 6-16 carbon atoms, 20-80% by weight of a component I2, which is a second surfactant containing alcohol groups other than an alkylpolyglucoside, the weight proportions being based on component I only; and a polymeric additive as component II, wherein the polymeric additive, as component III, contains at least one water-soluble moiety and at least one hydrophobic moiety, the ratio of the number average molecular weights of all water-soluble moieties to the number average molecular weights of all hydrophobic moieties being from 2:1 to 1000:1 or from 3.

Abstract: A method for increasing the efficiency of surfactants, broadening the temperature window, and suppressing lamellar mesophases in microemulsions by use of additives that possess at least one water-soluble unit and one hydrophobic unit are added to the microemulsions. The ratio of the number-average molecular weight of water-soluble units to the number-average molecular weight of hydrophobic units is 2 to 1000, the additives being polymers that comprise at least one water-soluble unit that possesses at least one hydrophobic unit on one chain end and/or one hydrophobic unit as a non-terminal substituent and/or at least one hydrophobic unit that is incorporated between the water-soluble units of the polymer.

Abstract: The invention relates to a method for improving the efficiency of surfactants with the simultaneous suppression of lamellar mesophases, in particular in micro-emulsions and emulsions and to surfactants, which are mixed with an additive. According to the invention, to improve the efficiency of the surfactants, a block copolymer of type AB, ABA or BAB is added to latter, said polymer comprising a water-soluble block A and an oil-soluble block B, which is a polyalkylene oxide, whose monomer units contain at least 4 carbon atoms. Said block copolymers also prevent lamellar mesophases, stabilise the temperature of the one-phase ranges for oil, water or surfactant mixtures, enlarge the structural quantity and reduce the interfacial tension of said mixtures.

Abstract: A sensor front end is disclosed that is able to discriminate objects based on their range from the sensor and to derive bearing information therefrom. The sensor system includes a signal source for transmitting at least a first and a second sensor signal toward the object and receiving a first and a second reflected signal pulse therefrom, and for generating a first and second information signal based on the first and the second reflected signals, respectively; and an information processor programmed to receive the first and second information signal from the signal source and to determine bearing information for the object based on a phase difference between the first and second information signal. The information processor is preferably capable of generating sample points from the first and second information signal and calculating the bearing information using these sample points.

Abstract: The present invention relates to semisolid transcutaneous medicaments based on at least one oxidation-sensitive progestin or a pharmaceutically acceptable derivative thereof. The medicaments comprise ascorbic acid, an ascorbic acid derivative or a salt thereof and have excellent stability. Corresponding gels which comprise a combination of norethisterone acetate and estradiol are described in particular.
