  • Patent number: 10271657
    Abstract: A foam seating article includes a layer of molded foam surrounding a hollow shell made of hard plastic. A fabric covering encloses the shell and molded foam. The foam seating article can take the form of a chair, stool, sofa, chaise lounge, bench or Ottoman. The hollow shell can be formed using blow molding, injection molding or by capping both ends of a tube with disks. Air pressure inside the airtight hollow shell prevents the shell from collapsing inwards under the weight of an occupant. Alternatively, the hollow shell of the seating article can be accessed through a removable lid. The seating article includes no wood or metal. The layer of molded foam includes sections of different foam types, such as high density (HD) foam, memory foam and latex foam. Molding foam around a hard plastic shell is simpler and less costly than making conventional metal or wood framed furniture.

  • Patent number: 10272669
    Abstract: Improved pliable print rollers for high speed drink can printing machines increase the pliable roller life five- to ten-fold at comparable ink thickness and machine speed. The improved performance results from the selection of materials utilized including a combination of elastomers, and in some case an essentially oil-free composition, and an associated manufacturing process not previously utilized to create pliable print rollers for high speed drink can printing machines. In particular a particular embodiment, the composition includes a combination of elastomers (e.g., 75% polyisoprene and 25% polybutadiene), a filler (e.g., silica), a curing agent (e.g., peroxided), and other additives (e.g., pigment, antioxidant, antiozonant) with little or no oil added as a softener. An illustrative composition including 150 parts by weight contains 100 parts elastomer, 35 parts filler, 4 parts curing agent, and 11 parts other additives (i.e., zero parts oil softener).

  • Patent number: 10267349
    Abstract: A fastener which comprises a tubular member, a sleeve, a spring, a shank, and an elongate head. A lower end portion of the shank extends through the tubular member to threadedly engage a lower part. The elongate head rotates within a slot in the upper end of the shank between a first position extending longitudinally of the shank so that it can receive an upper part to be attached to the lower part and a second position extending radially of the shank to prevent removal of the upper part. The shank is received within the sleeve and has a pair of slots in its upper end which are alignable with the shank slot. The sleeve is biased to an upper position by the spring, which is in the tubular member. When the sleeve is in a position wherein it is biased upwardly, the sleeve partially covers the shank slot to prevent rotation of the elongate head between the first and second positions.

  • Patent number: 10246887
    Abstract: The method includes a tension element, for example in the form of flat steel, that is placed on the structure or structural part and can be guided around a corner. The flat steel can also wrap as a band around the structure, in which the two ends of the flat steel are either connected to one another or are separately connected to the structure by the end anchors or intersect to produce a clamping connection. The flat steel contracts as a result of a subsequent active and controlled input of heat using a heating element and generates a permanent tensile stress and, correspondingly, a permanent prestress on the structure. The structure, as equipped, has at least one tension element as a shape memory alloy which extends along the outer side of the structure and is connected by one or more end anchors.
