A conveying system (1) for conveying a material along a conveying path. The system (1) includes a system housing (3) having a conveying chamber (5), in which the conveying path is arranged, and having at least one secondary chamber (6 to 8), which is connected to the conveying chamber (5) by at least one passage opening and has a fluid atmosphere that is physically and/or chemically different from the fluid atmosphere in the conveying chamber (5). The at least one passage opening (9, 10) and the fluid atmospheres in the conveying chamber (5) and the at least one secondary chamber (6 to 8) set a defined fluid flow in the system housing (3).

A continuous heating furnace including an inlet, a heating zone, a cooling zone and an outlet in this order, for carrying out a heat treatment while conveying at least one workpiece from the inlet to the outlet, wherein the cooling zone is configured such that an ambient gas for direct cooling of the workpiece can flow into the cooling zone from the outlet; the cooling zone includes a plurality of indirect coolers arranged in parallel in the conveying direction of the workpiece, each of the indirect coolers having at least one regulator for independently adjusting a cooling power; and the cooling zone includes one or more residual heat outlets for discharging a residual heat gas in the cooling zone.

A substrate processing apparatus includes: a heat processing unit configured to perform a heat process on a substrate having a film formed on the substrate; and a control unit configured to control the heat processing unit, wherein the heat processing unit comprises: a heater configured to support and heat the substrate; a chamber configured to cover the substrate supported on the heater; a gas ejector having a head in which ejection holes are formed, and configured to eject a gas from the ejection holes toward a surface of the substrate; an outer peripheral exhauster configured to evacuate a processing space inside the chamber from an outer peripheral region located further outward than a peripheral edge of the substrate supported on the heater; and a central exhauster configured to evacuate the processing space from a central region located further inward than the peripheral edge of the substrate supported on the heater.

The invention relates to a material feeding system (1) for a melter comprising: (i) a substantially horizontal feeding barrel (5) designed to feed solid material through the melter wall (9) into the melt (11) contained in the said melter, and arranged below the level (13) of the melt (11) contained in the melter (30), (ii) said feeding barrel (5) comprising a material input opening (15) and material output opening (17), the material output opening (17) leading into the melt (11) contained in the melter (30), said feeding barrel (5) comprising an internal feeder (20) designed to push solid material (7) loaded through the material input opening (15), in the direction of the longitudinal barrel axis (6) toward the material output opening (17), the end of the internal feeder (20) on the material output side extending at a minimum at a distance from the internal melter surface (19) of two (2) to ten (10) times the diameter of the feeding barrel (5), preferably three (3) to eight (8) times the diameter of the feeding barrel, more preferably three (3) to six (6) times the diameter of the feeding barrel or three (3) to five (5) times the diameter of the feeding barrel (5). The invention further covers a submerged combustion melter equipped with above material feeding system and a process for feeding material into a melter.

The invention relates to an arrangement of a furnace and of bulk material of glass particles, said furnace (10) comprising a pressing punch (36), a pressure, distance and/or speed sensor and a control device for controlling a pressing process based on the output signal of the sensor. The sensor detects at least a pressure, position and/or motion parameter of the pressing punch (36). The pressing punch (36) acts on the bulk material of glass particles (32)—possibly via an interposed ram (28)—, said glass particles being guided and crystallizable in a press channel (30). The trigger criterion for the process control is a change of at least a motion parameter of the pressing punch (36) upon softening of the bulk material of glass particles (32) which change is detected by the sensor.

The present invention relates to a device for carrying component parts to be temperature-controlled, in particular coiled metal strips or metal wires, in a temperature-control device. The carrier device has a base body and a carrier element, to which a component part is attachable, wherein the carrier element is detachably attached to the base body. The base body has a transport coupling, which is configured such that the transport coupling is detachably fixable to a handling system for handling the device.

A substrate processing apparatus, comprising a substrate support (32) provided with a support surface (34) for supporting a substrate or a substrate carrier (24) thereon and a support heater (50) constructed and arranged to heat the support surface (34). The apparatus comprises a heat shield constructed and arranged to cover and shield the substrate support (32) when no substrate or substrate carrier (24) is on the support surface.

The invention concerns a method for feeding an optical cored wire into a molten metal bath and an immersion system and an immersion nozzle to carry out the method. The optical cored wire (6) is decoiled, a feeding and straightening device (4) with a plurality of rollers (20, 21) conducts feeding of the optical cored wire (6) in a feeding direction towards the metal bath (11) as well as a first straightening of the optical cored wire (6), and subsequently a separated further plurality of non-motor driven nozzle straighteners (13) arranged between the feeding and straightening device (4) and the metal bath (11) conducts a second straightening of the optical cored wire (6). Very high precision of temperature measurement can thereby be achieved.
