  • Patent number: 10494125
    Abstract: The present invention relates to a device in a filling machine, said filling machine comprising a filling pipe for supplying liquid food to the tube of packaging material, a pipe for supplying pressurized sterile air to the tube of packaging material, and a gasket for sealing against the tube of packaging material and any pipes inside the tube, for creating an overpressure in the tube. The device further comprises a first pressure gauge for measuring a first pressure inside the pipe at a location upstream from the tube, a device for determining an air mass flow in the pipe, and a control unit for receiving the measured parameters, where the control unit is adapted to calculate the pressure in the tube based on the air mass flow and the first pressure, according to a first pre-established relationship. The invention also relates to a method being implemented by the device.

  • Patent number: 9505152
    Abstract: A porous hardenable drainage element is produced from a molding compound of expanded plastics granulate and a bonding agent by virtue of the fact that the molding compound is received in a ladle having a pouring opening closed off by a mold bottom, the molding compound is pressurized in the ladle, the element is molded from the molding compound in a mold formed by lowering of the mold bottom down into an opening cross section consistent with a cross section of the pouring opening, and the element is separated from the molding compound by mutual lateral displacement of the mold and the ladle.

  • Patent number: 9377033
    Abstract: A gerotor pump including a housing which includes a first supply socket and a second supply socket, an inner rotor, and an outer rotor rotatably located relative the housing. The inner rotor is located within the outer rotor, lobes of the inner and the outer rotors are engaged, and the inner rotor is centered around a rotational axis which is eccentric from an axis of rotation of the outer rotor. A pressure chamber with a high pressure and a low pressure section is defined between the inner and outer rotors. The inner rotor is rotatably arranged on a shaft cylinder which is fixed at one end of a central drive shaft of the pump and is centered about the rotational axis, whereby the inner rotor wanders in the outer rotor when the central drive shaft is turned. The inner rotor is provided with radial supply conduits extending from the pressure chambers to the shaft cylinder.
