  • Patent number: 10190052
    Abstract: A device and a method are provided for regulating and controlling individual gas pressure of individual ovens of a coke oven battery, in the case of which a rising-pipe bend projects, preferably from above, into a collecting main. The lower end thereof is associated with an immersion pipe via a water labyrinth seal. The immersion pipe is supported such that it is vertically adjustable by means of an actuator, and an immersion cup is located preferably below the immersion pipe. The rising-pipe bend has arranged therein a sleeve, the lower end of which is connected via at least one conduit to the water labyrinth seal. A water supply for feeding the water labyrinth seal and the actuator are provided at the top, outside the rising-pipe bend. Regulation of the gas pressure is accomplished by different immersion depths of the immersion pipe and the constant water level in the immersion cup.

  • 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: 6288329
    Abstract: A foldable blank includes a substrate and a conducting layer. The substrate is folded so as to form a component housing. When the substrate is folded to form a housing, the conducting layer provides electrical shielding to devices situated within the housing. The housing has holes situated therein to accommodate air flow and external connections to devices located within the housing. The housing may be employed to envelop a chassis manufactured from expanded polypropylene.

  • Patent number: 6011701
    Abstract: The housing assembly for holding device components comprises a housing and a chassis and can be integrally coupled to a standard piece of furniture. The housing may be in the form of a drawer which can be inserted and withdrawn from a standard unit of furniture such as a desk or cabinet. The drawer has perforations in its bottom and sides for air flow and is preferably made from a metal or metallic material but alternatively may be made from a non-metallic material which is lined with a metallic film. The chassis is made of plastic, preferably expanded polypropylene and may comprise two parts in which are secured equipment components. Projections extend from the sides of the chassis and extend to the drawer walls and thereby create air ducts through which air may flow to cool the components situated in the chassis. Plastic inserts may be placed in the air ducts created by the projections so as to direct the air flow within the assembly.
