  • Patent number: 8038800
    Abstract: The invention relates to a method and a device for cleaning the door of a coke oven, said door comprising a sealing edge and a membrane that is attached to the door panel of the coke oven. According to said method, cleaning tools comprising jet nozzles, which are supplied with a flow medium at high pressure, are situated and displaced back and forth in the region between the sealing edge and the door panel of the coke oven, in such a way that the interior surface of the membrane and the sealing edge are cleaned. The coke oven door is cleaned directly after the coke oven chamber is opened, by at least one jet nozzle element, which is supplied with compressed air and is displaced along the sealing edges. The jet nozzles are oriented in such a way that the air hits the surface to be cleaned at an acute angle.

  • Patent number: 8028542
    Abstract: Glass articles are made by continuously emitting a plurality of strands of molten glass spaced different distances from respective preform molds, cutting through each of the strands by moving together a respective pair of blades to form a respective gob, and transporting the gobs through the respective distances to the preform molds. The pairs of blades are operated, that is moved from an open to a closed position, such that they cut through the respective strands one after the other with the first formed gob traveling through the longest distance to the respective preform mold and the last formed gob traveling through the shortest distance to the respective preform mold.

  • Patent number: 8017717
    Abstract: Polyesters such as polyethylene, polypropylene and polybutylene terephthalate are made from melts of precondensates of polyesters by first conducting vapors comprising precondensate components distributed in the form of an aerosol through a polycondensation reactor in which precondensate components are deposited on the reactor wall and in an outlet chamber of the reactor on a separator. Then the deposits are conducted to the unstirred discharge sump. Upper layers of the discharge sump are continuously recirculated in the stirred reactor area and thus subjected to reconversion and further polycondensation.

  • Patent number: 8016121
    Abstract: Disclosed is a droplet separator system which is disposed in or on a flow duct and is used for separating liquid and/or solid particles from the medium flowing in the flow duct. The system comprises a frame with a base plate, a cover plate, and a trough that is located at the bottom end of the frame and is used for collecting and discharging liquids/solids, a cap area and a lateral area. A plurality of profiled droplet separators (3) is retained by the frame. The frame is provided with at least one device for deflecting and/or increasing the resistance and/or reducing the rate of the flow, the device being arranged in and/or adjacent to the trough area, cap area and/or lateral area of the frame. This allows entrainments or leakage flows to be largely eliminated.

  • Patent number: 8011219
    Abstract: The invention relates to a method for adjusting the position of a mandrel (10), which is situated in a hydraulic punch consisting of a cylinder and a ram that form a mandrel cylinder (8), in an extrusion press for producing pipes (2), which are extruded from blocks (4) that are loaded into a receiving device (5) situated upstream of the extrusion press (3) and are punched using the mandrel (10). The invention is characterised in that the mandrel cylinder (8) is driven directly by pumps (11), which are set for a pre-calculated throughput that is dependent on the press speed, and that an additional throughput is added to the pre-calculated pump throughput. To adjust the position of the mandrel (10), a control valve (16) that acts on the ring side (12) of the mandrel (8) is connected to a tank (17).

  • Patent number: 8007300
    Abstract: A bipin fluorescent-lamp holder has a housing formed with an outwardly open housing mouth and a rotor rotatable in the housing adjacent the mouth about an axis and having a diametrally throughgoing rotor slot. The rotor is rotatable between an installation position with the rotor slot aligned with the slot and an angularly offset contact position with the slot not aligned with the mouth. The rotor and housing are so dimensioned as to receive the pins extending parallel to the axis and to move the pins in a circular orbit centered on the axis on rotation of the rotor in the housing, and contacts in the housing diametrally flanking the axis each having a main part lying outside the orbit and a contact part engageable into the orbit. The contacts pins are aligned with the slot and project into ends of the slot and into engagement with the pins only in the contact position of the rotor.
