Abstract: Technologies for supporting concurrency of a flow lookup table at a network device. The flow lookup table includes a plurality of candidate buckets that each includes one or more entries. The network device includes a flow lookup table write module configured to perform a displacement operation of a key/value pair to move the key/value pair from one bucket to another bucket via an atomic instruction and increment a version counter associated with the buckets affected by the displacement operation. The network device additionally includes a flow lookup table read module to check the version counters during a lookup operation on the flow lookup table to determine whether a displacement operation is affecting the presently read value of the buckets. Other embodiments are described herein and claimed.

Abstract: An automatic fastening machine where strips of covered fasteners (11) are fed from a reel 16 of fasteners into the rear of the fastening machine along a guide means (12) as needed. A fastener advancing means (13) intermittently urges the strip of fasteners toward a drive element (60). The drive element engages the top of the foremost fastener of the strip of fasteners to force the fastener into a work piece.

Abstract: A fastener machine and fastener supply magazine therefor include a fastener guide in the machine and means for impelling fasteners along the guide to a fastened driving head, while the magazine automatically feeds clips of fasteners to the guide means from a stack of fastener clips contained in the magazine.

Abstract: An automatic fastening machine where clips of cohered fasteners (11, 15) fall freely onto a guide means (12) as they are needed and a fastener advancing means (13) intermittently urges the clips of fasteners toward a drive element (60). The drive element pushes the frontmost fastener on a clip into a work piece and an anti-jamming device (18-20) clears any jammed fasteners from the drive element.

Abstract: A clamp assembly 11 holds two frame elements 2, 3 in a common plane and in angled abutment to form a mitered joint 1. A fastener tool 13 is held with its discharge opening 125 positioned on one side of the location where the mitered joint is to be formed, and a brace 88 is positioned on the other side, with the brace being movable toward and away from the location of the mitered joint. A toggle lock 87 locks the brace against the mitered joint. Control means fire the fastener tool in response to the frame elements being clamped and braced. The fastener 168 is inserted into the mitered joint at an angle to draw the mitered joint together.
