  • Patent number: 5033204
    Abstract: The dehydration process substantially consists in causing the fabric in rope form to continuously advance between at least two pairs of pressing rolls, with it being simultaneously submitted to a false twisting. The false twist causes a wringing of the fabric with the consequent partial evacuation of the liquid the fabric is sodden with. In order to improve the dehydration, a centrifugation of the twisted fabric is provided. The apparatus substantially comprises a twisting organ capable of giving a false twist to the running fabric. The twisting organ can be constituted by a revolving structure capable of causing the fabric to run along a path outside its advancement axis, with the fabric thereby simultaneously undergoing a twist and a centrifugation.

  • Patent number: 5027529
    Abstract: A compressed air system includes an electronic control which controls enabling and disabling of the compressor in response to pressure level variations in the system storage reservoir. The control unit responds to compressor disabling by causing the system air dryer to regenerate or purge for a predetermined time period. The timing period of a charge timer is initiated when the compressor is enabled. When the charge timer has timed out, the compressor is disabled and the air dryer purged for the predetermined time period.

  • Patent number: 5025570
    Abstract: An oven employing a group of identical modular oven units, each unit divided into a main cavity with a first upper auxiliary chamber and a second lower auxiliary chamber. A barrier plate separating the upper chamber from the main cavity is gas pervious and serves as a filter to separate micron size particles and larger from entering the main chamber as the particles are carried by heated inert gas or air passing into the main cavity. The barrier plate separating the lower chamber from the main cavity is also gas pervious and serves as a sink to adsorb particles of sizes up to 100 microns. The group of modular ovens is partially surrounded by a heat transfer wall which allows heat to be rejected from the modular ovens and removed by a fluid coolant in contact with the wall.

  • Patent number: 5025571
    Abstract: A heater equipped pre-trap chamber is provided at the upstream side of the inlet to a vacuum diaphragm pump so that gas products and solvent drawn from a specimen in a drying chamber can be subjected to a separation operation in the pre-trap chamber to remove liquid and readily condensable vapor forms of solvent. This thereby prevents entry of liquid solvent to the pump unit where it could cause damage. The inlet to the pump is located some distance above the outlet from the pre-trap chamber so that any liquid as may carryover in the flow from the pre-trap chambers towards the pump inlet, will return to the pre-trap as a gravity induced back flow. Solvent collected in the pre-trap chamber is heated to vaporize it and pass it out through the pump in that form to the outside atmosphere, making the pre-trap self-cleaning.

  • Patent number: 5016364
    Abstract: A drying apparatus which utilizes air circulation to uniformly dry articles is disclosed. The apparatus includes an enclosure having racks upon which the articles to be dried are placed. An air exchanger couples to the enclosure to recirculate and heat air within the enclosure. Recirculation operates continuously while articles are being dried, and recirculation air temperature is maintained around a predetermined level through a thermostat coupled to heating elements. The air exchanger is configured so that air expelled from the air exchanger travels upward near the enclosure's walls, then downward in the center of the enclosure back to the air exchanger. An exhaust fan is controlled by a humidistat to remove humid air from the enclosure whenever the humidity within the enclosure exceeds a predetermined level. Consequently, a mean humidity level is maintained within the enclosure to prevent excessive drying, and substantial recirculation of air results in improved efficiency.

  • Patent number: 5012767
    Abstract: Pendant superheater or reheater tubes are maintained in spaced relationship by pairs of collar elements joined together in a closely adjacent relationship. One of the collar elements is dimensioned allow for vertical movement of the tube over which it is fitted throughout the range of temperatures to which the tubes are exposed. The other collar is mechanically fixed to the adjacent tube without welding or other means of physically joining in a manner which prevents vertical or rotational movement. The paired collars are physically joined as by welding so that the fixed collar fixes the spacing between tubes and maintains them in the same horizontal plane while allowing for relative vertical movement. As illustrated the fixed collar is locked by being mounted on a curved tube section having a curvature sufficient to prevent relative vertical movement and through interference with the collar wall to prevent relative rotational motion.

  • Patent number: 5010659
    Abstract: An infrared drying system for monitoring the temperature, moisture content, or other physical property at particular zone positions along the width of a traveling web, and utilizing a computer control system to energize and control for finite time periods a plurality of infrared lamps for equalizing physical property and drying the web. The infrared drying system is particularly useful in the graphic arts industry, the coating industry and the paper industry, as well as any other applications requiring physical property profiling and drying of the width of a traveling web of material. The infrared drying system profiles a physical property across the width of the web by a sensor head which travels on a belt supported above the web, and inputs the information into a computer to generate signals corresponding to the measured physical property for each particular segment portion along the width of the web above or below a setpoint.

  • Patent number: 5007181
    Abstract: A method for making stir-in type halophosphate phosphors to obtain a fluffy, deagglomerated powder is disclosed. A wet phosphor filter cake is fed into a toroidal-shaped direct-fired glass flash dryer in which a hot gaseous stream is circulating. The wet phosphor particles are suspended in the stream while the remaining liquid is evaporated. The dried phosphor powder is ejected from the dryer by centrifugal force and collected. Recovery efficiency of the process is about 99.9 percent.
