  • Patent number: 6386254
    Abstract: A device for encapsulating a monitoring device for a pneumatic tire with an encapsulation material includes an encapsulation body having an encapsulation chamber. The monitoring device has at least a pressure sensor and an antenna. A damming element is carried by the encapsulation body in an adjustable manner such that the damming element contacts the pressure sensor of the monitoring device when the monitoring device is disposed within the encapsulation chamber. The damming element prevents the pressure sensor from being clogged with the encapsulating material when the monitoring device is encapsulated. The antenna of the monitoring device is held in a channel formed in the body when the monitoring device is disposed within the encapsulation chamber. The connection between the antenna and the body holds the monitoring device in a floating disposition in the encapsulation chamber. The damming element is in the form of a tube that also helps carry the monitoring device in the floating disposition.

  • Patent number: 5350470
    Abstract: A method of forming a bead assembly for use in a pneumatic tire includes extruding a strip of green elastomeric material onto a split or pair of steel supporting guide ring where the ends of the extruded strip are cut at a bias angle and then spliced together to form an annular elastomeric member. The extruded strip and formed annular member has a pair of tapered longitudinal end members joined by a central recess. An annular tire bead is placed in radial alignment about the central recess of the annular member. Next, a segmented mandrel carrying inflatable turnup bladders is expanded outwardly, afterwhich the split guide ring is axially withdrawn. The mandrel and bladders then provide the support for the elastomeric member previously provided by the split annular ring, and traps the bead within the central recess. The two longitudinal end members of the extruded strip are then turned up about the bead by inflating the bladders to form the bead assembly, afterwhich the assembly is placed in a shaping mold.

  • Patent number: 4638532
    Abstract: A mechanical fastening system for securing a flexible sheet within a channel member via an insert member wherein the latter is made of flexible resilient material having a central longitudinal flex notch that serves to define two adjacent wing portions and permits a temporary elastic deformation of the insert member into an inverted V-shape for insertion of the insert member, together with the flexible sheet, into the channel member. A method for securing the flexible sheet within the channel member, via the resilient insert member, is also presented.

  • Patent number: 4617771
    Abstract: A non-penetrating mechanical fastener for securing a flexible sheet of an elastomeric material to the upper surface of a roof via the use of a plurality of such fasteners, each of which includes upper and lower members, wherein the latter are anchored to the roofing surface. The upper member includes a snap-ring which clamps the sheet within an annular boss formed on the lower member and a locking cap which is engaged by an interference fit with the snap-ring to lock the ring in position within the boss. A method for securing the flexible sheet to the roofing substrate also is presented.

  • Patent number: 4534145
    Abstract: An attachment device for securing a flexible sheet within a channel member via an insert member of generally inverted V-shape wherein the latter is made of a ductile but rigid material having a central longitudinal portion of reduced rigidity that serves to define two adjacent wing portions and permits the subsequent plastic deformation of the insert member into its installed shape after its insertion, together with the flexible sheet, into the channel member. A method for securing the flexible sheet within the channel member, via the ductile but rigid member, is also presented.
