Abstract: An extraction device for a filter element containing collected particles of target material and an extraction fluid, wherein the device may have a piston and a vibration apparatus for vibrating the filter element to cause particles to move from the filter element and into the extraction fluid. The piston may first create compressed air to urge a first amount of extraction fluid and particles out of the filter element, and may then compress the filter element to urge a second amount of extraction fluid and particles out of the filter element.

Abstract: Extraction devices are disclosed for extracting liquid particulates from a gaseous stream. The extraction devices may have a powered or free spinning rotating extractor that may be mounted in the extraction device's source or extraction duct. During operation, liquid particulates impinging on the rotating extractor form a thin film of extracted liquid that travels due to centrifugal force to the periphery of the extractor's exterior surface where the extracted liquid may be flung to the inner surface of the extraction duct and collected.

Abstract: Linerless label stock 102 is fed to a printer that prints on the front face 104 of the label stock 102 and then to a media cutter 224. The cutter 224 cuts the strip into discrete labels, which are fed to a tag application station 226. A strip of electronic tags is fed through an encoder that detects defective tags and then to a tag cutter 246 that cuts the strip into discrete tags. Defective tags exiting the cutter 246 are diverted away from the tag application station. Non-defective tags are conveyed to the tag application station 226 where they are secured to the back face of labels.

Abstract: A system includes a method and apparatus for printing labels and applying electronic tags, e.g. RF tags, to the labels, and also includes the resulting labels. The apparatus comprises a label media supply station that receives a strip of label media. The back face of the media may have adhesive thereon, which may be protected by a liner. The media is conveyed to a print station for printing on the front face of the media. A strip of RF tags is conveyed from a tag supply station to a tag application station downstream of the print station. At the tag application station, an electronic tag is applied to the back face of a label that has been printed at the print station. Preferably, a tag strip bar defines the location at which a tag is brought into contact with the back face. The bar is configured to provide a sharp turn in a pathway for a liner portion of the strip of tags. This separates the liner from the tag as the tag is applied to the label.

Abstract: This is a cutter assembly for linerless strip media having an uncovered adhesive backing. There is a cutter for transverse movement across the media and a backing bar with at least two cutting edges. The backing bar can be rotated to place one of the cutting edges in contact with the cutter. A cleaning station cleans the previously used cutting edge as the bar is rotated. Rotating and fixed cutters can be used. The cutter is replaceable and can be supplied in combination with as associated media for which it is designed. The cutter may partially cut the media to make it separate without fouling the cutter with adhesive. A self-healing "solid" roller is also disclosed.

Abstract: A printer has a print station and a guide path extending from a media roll station to the print station. Guide apparatus includes an inner edge guide extending along and defining an inner side edge portion of the path. In one embodiment, lateral tracking of the media through the print station is provided by a retractable outer edge guide. The outer edge guide automatically retracts when media is moved into the path through the outer side thereof. The outer edge guide is adjustable to firmly grip the opposite edges of the media between the inner and outer edge guides. In another embodiment, there is no outer edge guide. Instead, one or more tracking wheels are urged against a face of media moving along the path. The wheels are canted in order to provide a laterally inward force on the media. The laterally inward force automatically urges the media against the inner edge guide in both directions of media motion.

Abstract: This is a printer for printing on a printing face of a strip media having adhesive on a back face opposite the printing face. There is a moving surface of a release material which does not bond to the adhesive extending linearly between an entrance and an exit of a print zone to provide a temporary liner supporting strip media within the print zone. A drive mechanism moves the strip media through the print zone in combination with the temporary liner. A printhead is located within the print zone for printing on strip media within the print zone. Finally there is a member which non-contactingly releases strip media emerging from the print zone from the temporary liner.

Abstract: An apparatus for providing back tension onto a print media web comprises a plate having a post extended perpendicularly therefrom. The post is adapted to support a roll of print media thereon such that a web of the print media roll is paid out by rotation of the roll about the post. A constant-force spring is attached to a portion of the media plate at and has a handle coupled to an opposite end of the spring. A pressing element is coupled to the handle such that the spring is biased to urge the pressing element against the media supply roll to maintain the roll firmly in contact with the post during rotation of the roll. The force provided by the pressing element onto the media supply roll imparts sufficient back tension on the print media web to maintain a constant pay out rate. The present back tension apparatus provides a relatively simple mechanism that is readily adaptable for many conventional printers, such as a thermal transfer printer.

Abstract: A printer includes a variable torque assembly that allows a printer controller to vary torque on supply and take-up reels in response to monitored diameter of the supply or take-up reels. In one embodiment, the variable torque assembly is a torque divider that divides a fixed amount of torque between a supply reel and a take-up reel. The ratio of torques on the supply and take-up reels is controller by a control stepper motor that adjusts respective Acme gears to adjust pressure on respective clutch plates to increase or decrease the amount of "drag" applied by the clutch plates. In another embodiment, separate control stepper motors control torque to each of the supply and take-up reels so that the overall amount of torque can be varied to accommodate changes in print media lengths.

Abstract: This is a cutter assembly for linerless strip media having an uncovered adhesive backing. There is a cutter mounted for transverse movement across the media and a backing bar with at least two cutting edges. The backing bar can be rotated to place one of the cutting edges in position to cooperate with the cutter to cut the media. The backing bar is rotatable about a transverse axis simultaneously with feed movement of the media at a rotational speed equal to the feed speed of the media. This causes the media to ride up on a pointed portion of a cutting edge without dragging across the cutting edge as the cutting edge moves into a use position in which the media is supported by a support surface of the cutting edge. A cleaning station cleans the previously used cutting edge as the bar is rotated. Rotating and fixed cutters can be used. The cutter is replaceable and can be supplied in combination with an associated media for which it is designed.

Abstract: A system integrating a bar code printer and a bar code reader into a single functional unit having a single interface port which serves both the printer and the reader and communicates with a host computer. The interface port can include a parser to receive commands from the host computer and parse the received commands into printer and reader commands. The printer and the reader can communicate directly with each other without requiring the intervention of the host computer. The interface can include a wireless transceiver to permit remote operation of the unit. The unit can also be a stand alone system that does not require the host computer. In the standalone embodiment, an internal controller generates commands to control operation of the printer and receiver. The standalone instrument can also include an interface to communicate with an optional host computer.
