Abstract: The disclosed technology regards a magnetic liner including a liner, a plurality of magnet bases each having a recess formed on the top surface thereof, and a plurality of magnets, each magnet received and secured within the recess of a magnet base. The magnet bases are inlaid within the liner, spaced apart so that no surface of any of the magnet bases is in contact with any surface of any other magnet base. The disclosed technology further regards a method of manufacturing a magnetic liner, including applying an adhesive about each of a plurality of magnet bases, and positioning the magnet bases in a press mold. A liner material is placed above the plurality of magnet bases, and heat and pressure are applied. Finally, one magnet is secured within each magnet base.

Abstract: In many fields, such as manufacturing and mining, compressed air is used as a power source for industrial equipment, hand power tools, etc. Extensive compressed air systems are installed in these environments to supply compressed air where it is needed. In mining, extensive belts are frequently used to move mined material. Idler rollers are located intermittently along these belts. Embodiments of the present invention include compressors located within these idler rollers. As the belt moves and causes the roller to turn, a compressor within the roller generates compressed air. Because the belt moves nearly continuously, but the compressed air may not be consumed continuously, the air will be vented periodically. Embodiments of the present invention use these vents to clean the filters for the system. Also, some embodiments of the compressor may be produced using a laminated, or stacked, method.

Abstract: A reversible belt scraper has two opposed replaceable scraper blades and a central shaft. Each replaceable scraper blade has a scraping surface and a base opposite to the scraping surface. The body of the scraper blades from the scraping surface to the base is comprised of elastomeric material. The scraper blades have at least one bracket in their bases. In at least one embodiment, the scraper blades have a plurality of brackets in their bases. The brackets in the bases of the scraper blades attach to the central shaft. End mounts at the end of the central shaft provide a means to mount the reversible belt scraper. In at least one embodiment, the brackets in the replaceable scraper blades are formed in a manner to accommodate the other scraper blade and allow both scraper blades to be mounted in a single row of apertures in the central shaft.

Abstract: A wear and shock resistant multi-strata panel for lining a conveyor chute bearing aggregate, coal, and other bulk materials. The panel comprises a plurality of generally planar layers, and a plurality of panels may be used to line a chute. The layers are comprised of and sequentially arranged in a topmost ceramic layer, a corrosion-resistant first metallic layer, an elastomeric cushioning layer, and a bottom-most corrosion-resistant second metallic layer proximal to and in intimate contact with the chute support structure, or chute surface. The layers are consecutively bonded together to form a panel attached integrally to the chute structure.

Abstract: A wound dressing apparatus includes a patient interface configured to attach to an area of skin on a patient and extend around a wound on the patient. An access port extends from the patient interface and includes an aperture in the patient interface configured to provide access to the wound. An attachment structure extends about and out from an outer boundary of the access port. An access cap is configured to be removably attached to the attachment structure to provide an occlusive seal over the wound when attached to the attachment structure. A method of treatment utilizing the wound dressing apparatus includes attaching the patient interface to the area of skin on the patient extending around the wound of the patient. The access cap is removed from the attachment structure to relieve pressure from the wound. A treatment device is attached to the attachment structure of the wound dressing apparatus.

Abstract: A reversible belt scraper blade provides two opposed scraping surfaces on an integrally constructed body. Each scraping surface has an elastomeric wear region transitioning to an elastomeric central region. Two integral frame members are integrally joined into the central region. Each integral frame member runs the length of the belt scraper blade and is at least partially exposed at their ends. End mounts attach to the exposed integral frame members and the reversible belt scraper blade is reversible about the end mounts. The wear regions may have sub-regions of different hardness to provide good scraping qualities combined with improved structural rigidity. The central region may also have sub-regions of different hardness to improve structural rigidity.

Abstract: Dog retrieval toy consists of both a retrievable component and an attachable throwing arm. The retrievable component is composed entirely of rubber with its symmetry based around a hollow axis. The axis of the retrievable component is designed to fit perpendicularly into the distal gripping fingers of the attachable throwing arm. The axis of the retrievable component is hollow to accommodate treat material as well as decrease production costs by reducing the amount of material. While holding onto the handle of the attachable throwing arm, picking up the retrievable component is accomplished by fitting the retrievable components' axis into the throwing arm's distal gripping fingers by pressing the retrievable component against the ground with the attachable throwing arm. The retrievable component is released from the grip of the throwing arm simply by the force of the throw.

Abstract: A scalper blade assembly for cleaning a conveyor belt. The assembly includes an adjustment structure for adjusting a force applied against the blades for biasing the blades into engagement with the conveyor belt. The adjustment structure includes a ratchet mechanism for incrementally adjusting the biasing force and a clamping structure for maintaining the position of blades and resisting forces applied against the blades from the conveyor. In addition, a blade support assembly is provided for facilitating mounting and replacement of scalper blades. The support assembly includes a support member and a locking member located within the support member, where movement of the locking member relative to the support member is operable to engage and disengage engagement members associated with the blades in locking engagement with the support member.
