摘要:
Aqueous dispersions of a copolymer obtained by free-radical polymerization and containing from 0.01 to 40% w/w of polymerized units of comonomers having at least one aldehyde or keto group, which dispersions contain at least one polyisocyanate in which the isocyanate groups are blocked by oximes.
摘要:
A slide gate nozzle for a slide gate carried by a closure frame which includes two independent arms pivotally connected with a casting vessel for slidably moving the slide gate with respect to the casting vessel and for moving the slide gate away from the vessel to facilitate changing of the ceramic plates. Rocker frames are pivotally connected with the arms and include rollers on which a guide rail rides in the sliding direction of the slide gate, and the swivelly connected rocker frame assures even pressure of the ceramic plates.
摘要:
A gear transmission having at least one gear wheel stage, wherein at least one of the gear wheels is fastened coaxially on a hollow shaft that is rotatably mounted in a transmission housing via at least two shaft bearings. An outside-radial stage offset is formed on the hollow shaft as a seat for a broad rim gear wheel that approaches the plant radially on the inside.

Recombinant lentiviral vectors containing at least: a lentiviral backbone comprising essential lentiviral sequences for integration into a target cell genome; a nucleic acid encoding a CCR5 RNAi; and an expression control element that regulates expression of the nucleic acid encoding the CCR5 RNAi element, are provided by this invention. In an alternative aspect, the vector also contains polynucleotides encoding TRIM5 alpha and HIV TAR decoy sequences along with gene expression regulation elements such as promoters operatively linked to the polynucleotides. The vectors are combined with packaging plasmid and envelope plasmids and optionally conjugated to cell-specific targeting antibodies. Diagnostic and therapeutic methods for using the compositions are further provided herein.
摘要:
Planetary gearing, in particular multistage planetary gearing, is disclosed. The planetary gearing includes at least one drive shaft, an output shaft, a sun wheel, a ring gear, planet wheels assigned to the planetary gear train, a gear casing, in particular a multipart gear casing, a planetary gear train, in particular the second planetary gear train, comprising a planet wheel arm immovably arranged in a casing. The construction of such a planetary gearing is simplified compared to the prior art, thereby saving costs. This is achieved in that the planet wheel arm is integrally formed with a casing.

The invention relates to a gear transmission having at least one gear wheel stage (1), wherein at least one of the gear wheels (2a; 2b) is fastened coaxially on a hollow shaft (3) that is rotatably mounted in a transmission housing (5) via at least two shaft bearings (4a, 4b). An outside-radial stage offset (8) is formed on the hollow shaft (3) as a seat for a broad rim gear wheel (2a) that approaches the plant radially on the inside.
摘要:
A control device for use in the engine compartment or in the transmission of a motor vehicle. The control device has a housing comprising a housing section for a control unit. The housing also has a line section for the motor or transmission fluid. The line section is thermally coupled to the housing section for the control unit. Such a control device and a cooling arrangement therefore ensure that the electronic components in the control device are cooled such that a pre-determined temperature limit for the electronic components is not exceeded.
摘要:
A transmission, especially for wind power installations includes a planetary stage on the input side that is mounted upstream of at least one gear stage. The planetary stage includes at least two power-splitting planetary gears that are mounted in parallel. A differential gear that is mounted downstream of the power-splitting planetary gears compensates for an unequal load distribution between the individual planetary gears caused by their parallel disposition.
