  • Patent number: 8347617
    Abstract: A hydraulic two-circuit system (2, 4) for activating consumers (A1, B1; A2, B2; A3, B3) of a mobile unit, for example a track-laying unit, and an interconnecting valve arrangement (38), which is suitable for a two-circuit system (2, 4) of this type and via which the two circuits (2, 4) can be interconnected so as to add them together, are disclosed. According to the invention, the interconnecting valve arrangement has an interconnecting valve with two pressure connections (P1, P2), two LS input connections (LS1, LS2) and two LS output connections, wherein a valve body of the interconnecting valve is designed with four control surfaces, of which two control surfaces which act in one direction are acted upon by the highest load pressure (LS1) in the first circuit and by the pumping pressure (P2) in the second circuit, and the control surfaces acting in the other direction are acted upon by the highest load pressure (LS2) in the second circuit and by the pumping pressure (P1) in the first circuit.

  • Patent number: 8347653
    Abstract: The device for homogenizing a glass melt has a melt receptacle and at least one stirring device arranged in the melt receptacle. Each stirring device consists of a stirrer shaft and stirrer blades extending toward an inside wall of the receptacle, which are configured to produce an axial feed of the glass melt in an inner stirring region between the stirrer shaft and front ends of the stirrer blades. The melt receptacle and the stirring device are configured so that a melt flow caused by the axial feed, which is opposite to the axial feed, seals a gap formed between the inside wall and the front ends of the stirrer blades, so that the glass melt cannot flow directly through the gap to a lower axial end of the inner stirring region. The invention also encompasses a method of homogenizing a glass melt.

  • Patent number: 8349399
    Abstract: The method produces powder particles that are uniformly coated with functional groups. It includes homogenizing, in an agitator mill, a suspension of glass, quartz, glass ceramic, and/or ceramic particles in a suspending agent together with a coating agent, so that the particles in the suspension react with the coating agent in the agitator mill to form the uniformly coated powder particles with functional groups. Preferably a weight ratio of the suspending agent to the particles is from 0.5:1 to 5:1. The suspending agent is preferably an aqueous solvent and the coating agent is preferably a silane. The uniformly coated powder particles have a particle size (d50) of less than 2 ?m, have a specific surface of 5 to 40 m2/g, and are free of agglomerates.

  • Patent number: 8347652
    Abstract: The invention relates to a device for homogenizing a glass melt in a melt receptacle, wherein at least one stirring device is disposed in a melt receptacle, which comprises a stirrer shaft and a plurality of stirrer blades, and wherein a gap (16) is formed between a wall region of the melt receptacle and the stirrer blades. According to the invention, the respective stirring device causes an axial feed action in an inner stirring region between the stirrer shaft and the stirrer blades in order to feed the melt in the stirring region along the stirrer shaft. A melt flow brought about by the axial feed action seals the gap against direct passage of the melt. According to the invention, a very high gap width can be achieved, thus preventing the abrasion of materials in the region of the marginal gap. This also reduces the complexity required for adjusting the device. According to the invention, a high level of homogenization can be achieved regardless of the entry point of the inhomogeneities.

  • Patent number: 8352536
    Abstract: An interface makes it possible not only to link an automation system component in uniform fashion to a production management system but also to relieve the production management system. For this purpose a generic data server has a long-term data store integrated with the server, an integrated data analysis unit, and an integrated configuration means which is also usable for configuring the data analysis unit with respect to the analysis to be performed. The server relieves the production management system by performing preprocessing of data, and it simultaneously serves as a uniform interface between the production management system and the automation system component.

  • Patent number: 8347655
    Abstract: In the apparatus for producing glass reduction of reduction-sensitive components in the glass melt is reduced or preferably is prevented during the melting and/or fining processes by introducing an oxidizing agent into the glass melt. The apparatus has a melt crucible, a fining vessel, and a device for conducting oxygen and/or ozone into the glass melt in the melt crucible and/or fining vessel, in order to suppress reduction of reduction-sensitive components of the glass melt. A preferred embodiment of the apparatus has a metallic skull crucible, which includes the melt crucible and/or the fining vessel. The apparatus preferably includes a homogenization unit connected to the fining vessel to receive glass melt from the fining vessel in order to further process the glass melt after refining.
