  • Patent number: 7364634
    Abstract: A tufted carpet includes a primary backing having a back side and a face side, and a secondary backing. The carpet includes tufts of yarn sewn through the primary backing so as to be exposed on the face side and to form a plurality of back stitches on the back side. The yarn of the tufted carpet is a thermoplastic material having a yarn melting point. The secondary backing is a thermoplastic material in the form of a fluid-impervious film or a fabric having a softening temperature that is no lower than the yarn melting point, or a laminate having an inner and an outer layer, in which the outer layer comprises a thermoplastic material having a softening temperature that is no lower than the yarn melting point.

  • Publication number: 20060169762
    Abstract: An apparatus for receiving parcels having a structural frame and a parcel drop having a fully open and a fully closed position is disclosed. The apparatus includes a bin, a first opening between the bin and the structural frame through which patrons may deposit parcels into the bin at least when the parcel drop is in the fully open position.

  • Patent number: 6738080
    Abstract: A document processing control system with a graphical user interface having a display is provided. The document processing system further includes a memory manager for determining whether the information of the information set is of a first type or a second type.

  • Patent number: 6501485
    Abstract: A programmable message storage system for a multifunctional printing system is provided. The programmable message storage system includes a configurable database for listing a plurality of message identifiers, the plurality of message identifiers corresponding respectively with the plurality of messages. The plurality of code sets corresponds respectively with the plurality of message identifiers, and each code set controls a manner in which a corresponding message is displayed on the display screen. In practice, at least one of the plurality of code sets is user programmable so that, in response to user input, the at least one of the plurality of code sets is reconfigured in the database for changing the manner in which the message corresponding with the at least one of the plurality of codes sets is displayed as a function of said reconfiguring.

  • Patent number: 6479125
    Abstract: A tufted carpet is made by tufting yarn through a primary backing including a first backing layer and a second backing layer. The first backing layer is formed of a woven, non-woven or plastic sheet material, or a composite of a woven or non-woven material and a plastic sheet material. The second backing layer comprises a leno weave, open weave, plastic net or plastic sheet material. The first backing layer and the second backing layer are arranged so that the first backing layer forms a first side of the primary backing and the second backing layer forms an opposite side of the primary backing. The tufts of yarn that are sewn through the primary backing are exposed on the first side of the primary backing for forming face yams, and also form a plurality of back stitches on the opposite side of the primary backing. At least a major portion of the back stitches secure the first backing layer to the second backing layer.

  • Patent number: 6475592
    Abstract: A tufted carpet is made by tufting yarn through a primary backing of at least two layers, including a first backing layer and a second backing layer. The first backing layer is formed of a woven material, a non-woven material, or a composite of a woven or non-woven material and a plastic sheet material. The second backing layer is formed of a woven material of ribbons of polypropylene, polyethylene or combinations of polypropylene and polyethylene, a woven fiber glass material, a leno weave material, an open weave material, a plastic net or a plastic sheet material. A plurality of tufts of yarn that are sewn through the primary backing are exposed on one side of the primary backing for forming face yarns, and also form a plurality of back stitches on the opposite side of the primary backing. At least a major portion of the back stitches secure each layer of the primary backing to each other layer.

  • Patent number: 6069624
    Abstract: There is provided a system for a multifunctional printing system which controls a manner in which status message sets are displayed on a display screen of a corresponding user interface. As contemplated, a first service attribute designating set of information is displayed on the display screen at a first time and a second service attribute designating set of information is displayed on the display screen at a second time, with the second time being subsequent to the first time. In practice, a message manager determines whether a replacement operation has occurred with respect to the user interface such that a substantial portion of the first service attribute designating information set has been replaced visually by the second attribute designating information set. In response to determining that a replacement operation has occurred, at least a portion of a status message set currently being displayed is replaced with at least a portion of another status message set.

  • Patent number: 5962101
    Abstract: A carpet is tufted with a two-part primary backing. The upper, or face, backing is a conventional woven or non-woven polypropylene, and the lower, or back, backing is a stronger, open weave fabric. The tufts of yarn are sewn through both parts of the primary backing, which holds the parts together, and causes some of the back stitches to protrude for better coating with adhesive. The resulting carpet may be fully back coated, and may have a secondary backing adhered thereto. The lower backing prevents elongation, stretching and shrinking of the carpet during manufacture and subsequent processing.

  • Patent number: 5612113
    Abstract: A carpet including yarn pile extending from the face of a primary backing and a secondary backing bonded to the back of the primary backing has a thin film of liquid impervious thermoplastic material bonded either to the rear of the primary backing or to the rear of the secondary backing to provide a fluid barrier for preventing spills from seeping through to a floor beneath the carpet. The film is bonded to either backing by a hot melt thermoplastic adhesive or other non-aqueous adhesive. Additionally, the method of providing such fluid barrier for the carpet is disclosed.

  • Patent number: 3997876
    Abstract: Apparatus and a method for controlling the reading and writing operation of a peripheral storage system such that a magnetic recording medium, having small defective areas in the magnetic surface at which data cannot be reliably recorded may be used. Each data track on the magnetic recording medium has a reserve capacity which is used as a special gap. The recording medium is initialized such that the distance from a point of origin to a surface defect in each track is recorded in a header area in each track. The apparatus and method herein described cooperate with this initialized magnetic recording medium so as to control the format of data recorded onto the magnetic recording medium such that any defect in the recording medium will not affect a reading or writing operation of the storage system.
