  • Patent number: 6299730
    Abstract: A method and system for monitoring web defects along a moving web of paper involves determining a dimension of a web defect as the paper web moves along an established paper path in a machine direction. A distance from a side edge of the paper web to a location of the web defect is also determined as the paper web moves along the established paper path. A value indicative of a likelihood of paper web failure at the web defect is then established based at least in part upon both the determined dimension and the determined distance. A determination of whether to stop the moving paper web for repair of the web defect can then be made based at least in part upon the determined failure likelihood indicative value. An alternative technique involves establishing a plurality of paper web width regions. A dimension of a web defect is determined as the paper web moves along an established paper path in a machine direction. The web defect is categorized as falling into one of the established paper web width regions.

  • Patent number: 6259056
    Abstract: A method and system for identification of manufacturing components on an assembly line. The system is designed to be incorporated into a production line of a build-to-order plaint in which a series of components are arranged on the assembly line and different manufacturing operations are to be performed on each component. The components initially are identified by paper tags which are scanned into a manufacturing computer system, and each component includes an adhesive label which is capable of being laser engraved. The system includes a laser engraver, which is positioned immediately upstream of a first manufacturing operation, and the laser engraver is actuated by the factory computer system to etch an identification code on the adhesive label.

  • Patent number: 6249263
    Abstract: A product information display system has electronic display tags for displaying pricing and product information for products in stores or warehouses. The electronic display tags are electromagnetically coupled to a conductor. A control circuit is used to generate an information signal which contains a tag address and related data. A modulator circuit modulates an a-c. power signal with the information signal and applies it to the conductor for transmission to the display tags. Each of the display tags is equipped with a coil that is electromagnetically coupled to the conductor for picking up the signals carried by the conductor. A demodulator is used to demodulate the signal picked up by the coil to obtain the original information signal. Each of the display tags is provided with a manually operated switch for initializing the tags with initial addresses transmitted by the conductor.

  • Patent number: 6247292
    Abstract: The invention provides an improved package wrapping machine which produces a wrapped product having a good seal and a favorable appearance for packages of varying sizes and shapes. More particularly, these improvements are obtained by utilizing a novel film gripper having sections that are separately disengageable to release tension on lateral sections of the film web during the wrapping of smaller than average packages, thereby preventing unwanted stretching of the film so as to promote a good seal for the packaged goods and avoid the formation of unsightly film tails. Also in a preferred embodiment of the present invention, a novel package pusher is utilized to convey the package to be wrapped from a package infeed location to a registration position on the package wrapping elevator.

  • Patent number: 6241016
    Abstract: The present invention provides a pump drive assembly for a deep well, submersible, progressing cavity pump that includes an internal hydraulic pump for slowing the counter rotation of the polished rod induced by recoil in the sucker rod. The pump drive assembly includes a housing enclosing a hydraulic fluid reservoir and a gear chamber separate from the reservoir. A drive shaft extends into the housing and includes a drive gear integral with or keyed to the drive shaft. A main shaft also extends into the housing and includes a main gear integral with or keyed to the main shaft. The main gear is engaged with the drive gear within the gear chamber, where the gear chamber includes an inlet and an outlet channel providing fluid communication between the gear chamber and the reservoir, so that the gears form a reversible gear pump within the housing. The reversible gear pump operates to pump hydraulic fluid from the reservoir into the gear chamber and back into the reservoir.

  • Patent number: 6235210
    Abstract: The present invention provides a combination continuous and batch filtration system for a recirculating fryer where the continuous filter and batch filter assemblies are integrated into a single unit, utilizing a common pump. This unit is substantially compact and is therefore able to fit within the frame of most recirculating fryers. The outlets of the continuous filter and the batch filter are connected to a two-way valve, which is, in turn, connected to the inlet of the common pump. The valve allows an operator to selectively pump cooking fluid from either the continuous filter or the batch filter back into the fryer vat.

  • Patent number: RE37257
    Abstract: A transfer imaging system is disclosed wherein images are formed by image-wise exposing a layer comprising a chromogenic material and pressure rupturable capsules containing, as an internal phase, a photosensitive composition. In a preferred embodiment, the chromogenic material is encapsulated with the photosensitive composition. Upon exposure and capsule rupture the chromogenic material is image-wise transferrable to a developer or copy sheet where the chromogenic material reacts with a developer to form an image. Preferred systems are sensitive to U.V. or blue light in the wavelength range of 380 to 480 nm.
