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.

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.

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.

Abstract: A porous hardenable drainage element (14) is produced from a molding compound (10) of expanded plastics granulate and a bonding agent by virtue of the fact that the molding compound is received in a ladle (30) having a pouring opening (32) closed off by a mold bottom (44), the molding compound is pressurized in the ladle, the element (14) is molded from the molding compound in a mold formed by lowering of the mold bottom (44) down into an opening cross section (42) consistent with a cross section of the pouring opening (32), and the element is separated from the molding compound by mutual lateral displacement of the mold and the ladle (30).

Abstract: A thermoforming apparatus for forming a blank into a composite article. The thermoforming apparatus includes a forming tool. A forming member forms the blank over the forming tool. A first chamber is arranged for containing the blank. A second chamber is separated from the first chamber by the forming member. A first air circulator is configured to circulate air in the first chamber for achieving a heat distribution to the blank. The first air circulator includes a controllable valve member. The apparatus also includes a second air circulator. A method for forming a blank during circulation of air in a first chamber.

Abstract: A gerotor pump (1) comprising; a housing (2) which comprises a first and a second supply socket (18a, 18b; 19a, 19b), an inner rotor (4); and an outer rotor (5) rotatably located relative the housing (2); wherein the inner rotor (4) is located within the outer rotor (5), and lobes (13, 4) of the inner and the outer rotor (4, 5) engaging, the inner rotor (4) is centred around an axis (15b) which is eccentric from an axis of rotation (15) of said outer rotor (5), wherein a pressure chamber (7) with a high pressure and a low pressure section, is defined between the inner and outer rotor (4,), characterised in, that the inner rotor (4) is rotatably arranged on a shaft cylinder (10b) which is fixed at one end of a central drive shaft (10) of the pump (1) and is centred about said rotational axis (15b), whereby said inner rotor (4) wanders in said outer rotor (5) when said central drive shaft (10) is turned, and wherein the inner rotor (4) is provided with radial supply conduits (9) extending from the pressure cham
