  • Patent number: 11407020
    Abstract: A method for molding a sheet into a motor-vehicle component includes heating the sheet by a kiln, prior to forming the component. The kiln has a main body with a roller shape, having a plurality of sectors extending along a radial direction with respect to a longitudinal axis of the roller body. The sectors are configured to each receive a sheet, so that the main body with a roller shape is arranged to simultaneously carry a plurality of sheets. The kiln includes a plurality of heating elements in said main body with a roller shape and configured to heat only the first portion of the roller body, so that the roller shaped main body is designed to heat the sheets in a differentiated way, particularly at their areas in contact with said first portion of the roller body. The kiln includes at least one electronically-controlled drive motor, arranged to rotate the roller-shaped main body around the longitudinal axis of the kiln, so as to vary the position of the sectors with respect to the inlet and outlet ports.

    Abstract: A method for controlling a fuel supply to a plurality of burners of a burner group includes determining a temperature in the burner group as a control variable. The fuel supply to the burners of the burner group is specified in dependence on a control deviation of the temperature determined in the burner group to a specified setpoint temperature. The fuel supply is a common mean fuel supply that is specified for all of the burners of the burner group by a temperature master controller. The fuel supply is corrected for each of the burners or burner subgroups of the burner group. Each of the burners or the burner subgroups have a fuel supply slave controller. The fuel supply slave controllers use at least, one disturbance variable associated to the respective burner or the respective burner subgroup so as to perform the correcting.

  • Publication number: 20150017592
    Abstract: Devices and corresponding methods can be provided to monitor or measure temperature of a target or to control a process. Targets can have low, unknown, or variable emissivity. Devices and corresponding methods can be used to measure temperatures of thin film, partially transparent, or opaque targets, as well as targets not filling a sensor's field of view. Temperature measurements can be made independent of emissivity of a target surface by, for example, inserting a target between a thermopile sensor and a background surface maintained at substantially the same temperature as the thermopile sensor. In embodiment devices and methods, a sensor temperature can be controlled to match a target temperature by minimizing or zeroing a net heat flux at the sensor, as derived from a sensor output signal. Alternatively, a target temperature can be controlled to minimize the heat flux.

The lamp preferably includes two heating elements, a first element for initial heating, such as a heat blanket, resistive glass coating, or a submerged ring, and a second heating element generally providing both heat and lighting. A sensor measures the temperature of the liquid inside the lamp and the control system controls the heat sources to maintain the temperature within operating limits.

    Abstract: A heating device includes a heat applying member heated by a heat source, a pressure applying member pressure contacting the heat applying member with a prescribed pressure, and a temperature detection device that detects temperature of the heat applying member. A timing device is provided to count time elapsing from when the heat source starts heating the heat-applying member. A control device is provided to determine that heat application as a start up operation to the heating member is completed when the temperature detected by the temperature detection device reaches a prescribed threshold and the elapsing time counted by the timing device reaches a prescribed threshold.

    Abstract: The invention relates to a method for operating a firing furnace, in particular for the dental sector, in which the temperature is measured and, based on the measured temperature, a temperature control is performed. If appropriate, the temperature integral, recorded at discrete points, is determined over the course of time and in particular stored, and is used, if appropriate in addition to the temperature, for controlling the firing furnace.

  • Patent number: 6630991
    Abstract: A method of detecting a temperature of an object in a multiple-reflection environment by a radiation pyrometer includes the steps of detecting a radiation strength emitted from a target region of an object, applying a correction to the radiation strength so as to correct the effect of multiple reflections of a radiation emitted from the object, applying a correction to the radiation strength so as to correct a reflection loss caused at an end surface of an optical medium interposed between the object and a sensing head of the pyrometer, applying a correction to the radiation strength with regard to an optical absorption loss caused in the optical medium, and applying a correction to the radiation strength with regard to a stray radiation coming in to the sensing head from a source other than the target region of the object.

  • Patent number: 5006061
    Abstract: A method for bringing a plurality of steel slabs to rolling temperature uses a furnace having a controllable energy supply. To accommodate variation of slab temperature at entry, especially mixing of cold and hot slabs, at least one virtual slab corresponding to a group of the steel slabs is determined, and the energy supply is adjusted in dependence on the desired mean temperature at exit from the furnace of the virtual slab. Suitably the furnace has at least two zones each with an individually controllable energy supply, and virtual slabs are determined for the slabs in each zone. Then the energy supply in each zone is adjusted in dependence on the desired mean temperature at exit from the furnace of the virtual slab of that zone and preceding zones.
