  • Patent number: 8235254
    Abstract: An articulated driving mechanism for a dispenser which in one embodiment is a caulking gun has a series of rigid links that are secured to one another by pins. The pins can slide in a slot which allows the links to space away from one another in a first position or be squeezed side by side which then prevents any rotation in a second position. The links all have ratchet teeth to engage two different driving wheels. The two driving wheels rotate at different speeds which allows the links to be consistently opened before reaching a circumferential wheel so that then the spaced links can rotate and safely and reliably rotate as they follow the circumference of the wheel. The articulated driving mechanism is used as a substitute for a push rod in a caulking gun in at least one embodiment.

  • Patent number: 8074438
    Abstract: A link chain comprises a chain link including two shank portions and two arc portions connecting the two shank portions. The two shank portions and the two arc portions define an interior space of the first chain link; and a dividing element extends inwardly from an inside surface of one of the two shank portions and extends inwardly from the inside surface of the other shank portion. The dividing element divides the interior space into two movement spaces, and the dividing element has a centerline, and the centerline is not a straight line perpendicular to the shank.

  • Publication number: 20110281992
    Abstract: The roller chain comprises inner link plates, a bush, outer link plates, a connecting pin, and a roller. Each of the chain components has a zinc-iron alloy ground film formed on an iron-based base material by impact zinc plating and a first coating film formed by using a water-based rust preventive paint including zinc, nitrate, and an organic compound having a mercapto group other than a mercapto group-containing silane coupling agent. Then a second coating film is formed on the first coating film by using the top coat paint comprising a pigment, sodium silicate, and an acrylic emulsion or a polyurethane water-based composition.

  • Publication number: 20110203248
    Abstract: The invention relates to a link chain having two or more rows of chain elements, wherein the chain elements of one row are rotatably connected to those of the adjacent row in the chain plane in such a way that each chain element has two rotational axes, of which in each case one of the two rotational axes belongs to two different chain elements in adjacent rows, and that the chain elements of one row are connected to one another by means of toothings at their ends in such a way that the chain is flexible in the chain plane. The chain elements at one end of the link chain are likewise provided, at their outer side, with a toothing, which toothings are in engagement with an actuator. The actuator has a pneumatic, hydraulic, electromotive or manual drive. The actuator may be a latching fitting, wherein the latching fitting is provided with a connecting lug which has a toothing on its outer side, which toothing is in engagement with the toothing of the final chain element.

  • Patent number: 7971422
    Abstract: A device for fastening emergency equipment to a vessel includes a hydrostatic release mechanism, a tether, and a float-free link. The tether is attached to the hydrostatic release mechanism and provides an attachment point for lashing the emergency equipment to the vessel. The tether may also be threaded through openings in the curved partially tubular body of the float-free link. A breakable bridge is integrally coupled to the body of the float-free link to form a closed loop. The breakable bridge is designed to be the break point when the emergency equipment needs to be freed from a vessel that has sunk below a predetermined depth. When the vessel sinks below the predetermined depth, the hydrostatic release mechanism severs the tether thus freeing the emergency equipment from one point of attachment to the vessel. The bridge is designed to break when the strain on the fastening line, e.g., the painter line, is between a predetermined minimum force and maximum force.

  • Patent number: 7950213
    Abstract: A link belt for use as a conveyor belt or power transmission belt is provided. The belt is formed of a plurality of links forming a series in successive overlapping relation. The upper surface of each belt link includes an electrically conductive layer. Additionally, the lower surface of each belt link may have an electrically conductive layer. The conductive layer or layers provide an electrical path along the belt to impede the build-up of static electricity as the belt is run during use. A method for producing the conveyor assembly is also provided. A plurality of layers of reinforcing material are arranged in overlapping relation. A binding material such as thermoset urethane is deposited on the reinforcing material to bind the reinforcing materials together, thereby forming a composite material. An electrically conductive layer is deposited on the composite material, forming a conductive layer.
