  • Publication number: 20180029167
    Abstract: A brazing or soldering wire has a pair channels recessed therein. A divider separates the pair of channels. The divider has opposing walls extending outwardly from corresponding base portions of the pair of channels. A first engagement surface is located between the opposing walls. A pair of outer walls is separated by the pair of channels and the divider. A second engagement surface is formed between an outer surface of the elongated wire and a terminal end of one of the outer walls and is substantially coplanar with the first engagement surface. A third engagement surface is formed between the outer surface of the elongated wire and a terminal end of the other of the outer walls and is substantially coplanar with the first engagement surface. A cured flux solution is located within the pair of channels.

  • Publication number: 20170218683
    Abstract: Insulated doors with restorable breakaway sections are disclosed. An example door includes a first panel assembly including a leading panel and a trailing panel. The leading panel is to be in substantially coplanar alignment with the trailing panel when the first panel assembly is in a normal configuration. The leading panel is to be angularly displaced out of coplanar alignment with the trailing panel when the first panel assembly is in a dislodged configuration. The example door further includes a tension member to connect the leading panel to the trailing panel. The tension member is to resiliently urge the leading panel and the trailing panel toward each other in a horizontal direction. The tension member is to resiliently urge the first panel assembly toward the normal configuration when the first panel assembly is in the dislodged configuration.

  • Patent number: 9556672
    Abstract: Example roll-up doors are disclosed. An example roll-up door includes a track system and a curtain. The curtain blocks a doorway when a leading edge is at a closed position and unblocks the doorway when the leading edge is at an open position. The roll-up door further includes a track roller to vertically travel along a track system. The track roller is to be rotatable relative to the track system. The roll-up door also includes a windbar to be coupled to the track roller. The windbar is closer to the lintel when the leading edge of the curtain is at the open position than when the leading edge is at the closed position. The windbar is to be vertically movable with the track roller and to be rotatable relative to the track roller and rotatable relative to the track system.

  • Publication number: 20160108666
    Abstract: Example systems and methods for aligning roll-up door curtains are disclosed. An example door includes a roller that is rotatable about an axis. The door further includes a curtain having a wrapped section wrapped around the roller and an unwrapped section extending tangentially away from the wrapped section. The unwrapped section adjoins the wrapped section at a first point proximate a first end of the roller and at a second point proximate a second end of the roller. The axis is closer to the second point than to the first point when the curtain is at the intermediate position. In some examples, the door includes a guide member to guide the curtain on to the roller.
