  • Patent number: 8849171
    Abstract: In a device or method to fix print images on a recording material, a printing fluid comprising a carrier fluid and chromophoric solid particles are applied to the recording material, the chromophoric solid particles being applied in a form of the print images to be fixed. Hot waste gas and infrared radiation are generated with aid of a porous burner. The infrared radiation is directed towards the recording material in a drying chamber such that the carrier fluid polymerizes or is vaporized, whereby a gaseous air/oil mixture arises in the drying chamber. The air/oil mixture is influenced with aid of the hot waste gas of the porous burner.

  • Patent number: 7225560
    Abstract: A system for curing printing plates with controlled radiant energy sources. A conveyor moves a printing plate through a chamber having energy radiators above and below the conveyor. Power to the radiators is controlled for each radiator or to groups of radiators defining radiation zones. Curing time may be controlled by adjusting power to the radiators and adjusting the conveyor speed. Sensors detect a plate as it enters and exits the chamber. Heat sensors may detect chamber or plate temperatures. A color sensor may detect plate color as an indicator of degree of curing. A computer system stores curing scenarios and uses the sensor signals and operator inputs to control power to the radiators and conveyor speed to provide uniform curing of the plate.

  • Patent number: 6067726
    Abstract: A combination infrared/convection dryer or oven for drying travelling webs. A shutter assembly is provided between the infrared radiation source and the moving web in order to selectively expose the web to infrared radiation. Drying efficiency is optimized by adding heated impinged air at high velocity on the machine direction ends and between the infrared elements. The air being discharged on the web is heated as it is pulled across the elements to a centralized return air duct. The return air is pulled into the inlet of a close coupled supply fan which then discharges the air to the nozzles. A portion of the air is also exhausted to atmosphere to maintain the oven enclosure in a negative pressure state, thus drawing fresh make-up air into the oven housing through the web inlet and outlet slots. Flotation nozzles can be used where contactless support of the running web is desired. Enhanced drying of the web and/or a coating on the web at high speed is achieved without a concomitant increase in dryer length.

  • Patent number: 6016612
    Abstract: To dry semiconductor substrates, especially silicon wafers subsequent to rinsing after etching, the substrate is exposed to the action of radiation which contains an IR portion and a UV portion, the IR portion being greater than the UV portion. The IR-UV radiation quickly dries the substrate and prevents contamination of the substrate with undesirable particles or limits it to a nondisruptive degree. To execute drying with IR-UV radiation, an arrangement is proposed in which the substrate is moved through directly from the treatment liquid (rinsing medium) between two rod-shaped radiators which emit IR-UV radiation.

  • Patent number: 5369894
    Abstract: A moist web of exposed and developed photographic film or photographic paper is continuously advanced through a drying unit wherein selected areas of the path for the web are monitored by devices which generate signals denoting the heat absorptivity of monitored portions of the web. Such signals are processed and utilized to regulate the intensity of heat which is emitted by batteries of heating elements at both sides of the path for the running web. This ensures that the less developed portions of the web are subjected to sufficient heating action and that the more developed portions of the web are not overheated. The monitoring can involve ascertaining the intensity of heat which has penetrated through successive portions of the running web and/or ascertaining the intensity of heat which is reflected by successive portions of the running web and issues from heating elements designed to emit heat of known intensity.
