  • Patent number: 8099824
    Abstract: A squeezing device for a wiping cover of a flat-body wiper, the wiper cover hanging downward and partially detached from a wiper plate of the flat-body wiper in a vertical position of the wiper plate, the wiper plate including a downward facing pressure surface in the vertical position. The squeezing device includes a funnel-shaped squeezing shaft having a counterpressure surface in a lower region of the squeezing shaft. The squeezing shaft is configured to receive the wiper cover and at least a portion of the wiper plate in the vertical position of the wiper plate so that a squeezing pressure of the pressure surface against the counterpressure surface squeezes out the wiper cover. The squeezing shaft includes stabilizing devices configured to stabilize the wiper plate against tipping relative to a first plane from the vertical position. In addition a cleaning system including the squeezing device and a method of squeezing a wiping cover of a flat-body wiper with the squeezing device.

  • Publication number: 20110158242
    Abstract: Described are methods and systems related to transporting one or more object packets present in a nested hierarchy of one or more system landscapes. The object packets available for transporting from source systems to target systems present in the nested hierarchy of the system landscapes is identified. A transport request is generate for a collection of object packets of each source system in the nested hierarchy of the system landscapes. The transport requests are aggregated to render a nested transport collection. The nested transport collection is transported within the nested hierarchy of the system landscapes. The nested transport collection is deployed to assign the transport requests present in the nested transport collection to the target systems present in the nested hierarchy of the system landscapes.

  • Patent number: 7122379
    Abstract: A method of using Raman Spectra for determining the progress of a graft polymerization reaction is disclosed. The method entails (a) measuring at the beginning of the reaction and at a plurality of time intervals in the course of the reaction, continuously and on-site, the Raman spectrum in the wave number range of 100 to 4000 cm?1 of one or more of the monomers and/or polymers entailed in the reaction and of at least one internal standard and (b) recording the spectra and (c) adding reaction partners necessary to the reaction continuously and/or discontinuously and (d) calculating the change in concentration of the monomers and polymers by comparing the spectra of the monomers or polymers with the internal standard.

  • Patent number: 5152611
    Abstract: The invention relates to a heat-shrinkable article that is at least partially coated with a temperature indicator. This temperature indicator is composed of an organic polymer having a suitable bonding agent, whereby the organic polymer is contained therein in a finely ground condition. As a result of this condition, the appearance of the agent is opaque and has a color corresponding to the degree of granulation and material constituent. When the melting point of the composition is reached, the material melts and becomes transparent or at least translucent. The color of the article shows through, so that this color change can be interpreted as a temperature indication.
