Abstract: An automated inspection system for inspecting, sorting and re-coining each of the locking bar, the rack, and the pin of a rekeyable lock cylinder, as well as other small close-tolerance components in an average cycle time of 1.5 seconds. The inspection system includes a high-speed pneumatic sorting matrix which selectively transfers the components into various length measuring stations, camera inspection stations, mechanical gauge stations, and/or coining stations, and then positions the parts at those stations for combined gauge and visual tolerance checking and sorting. Defects are identified by a combination of visual and machine-gauge inspection, and the sorted components are sorted into three bins: rejects; good parts; and parts for coining. The inspection/sorting system is capable of tolerance-checking down to 0.00011811?, with a repeatability of 0.00005906.

Abstract: A rekeyable lock cylinder includes a lock cylinder body having an interior void and a plug assembly rotatably disposed in the lock cylinder body. The plug assembly includes a plug body having a keyway. A plurality of racks is movably disposed relative to the plug body. A plurality of key followers is positioned across the keyway and is moveably disposed relative to the plug body. Each key follower is configured to engage a respective rack of the plurality of racks. A key follower rotation member is drivably engaged with each key follower of the plurality of key followers. The key follower rotation member is selectively movable to rotate each key follower of the plurality of key followers to thereby disengage each key follower of the plurality of key followers from the respective rack of the plurality of racks to facilitate a keying of the rekeyable lock cylinder.

Abstract: A cylinder lock assembly includes a cylinder body and a plug assembly which is manufactured in a multiple of pieces to facilitate casting of each plug piece in a single operation. The plug assembly includes a plug body with a plug insert opening to receive a plug insert. The plug insert opening is generally L-shaped in cross-section to receive the plug insert which is correspondingly shaped. The plug insert includes a plug outer portion which defines an arcuate outer surface which corresponds with the outer circumference of the plug body when the plug insert is mounted therein. A plug pin chamber portion extends generally transverse to the plug outer portion to define a multiple of tumbler pin chambers which extend through the plug outer portion.

Abstract: A novel bandage dispenser is disclosed for dispensing bandages from a roll of sterilized, individually wrapped bandages. Several bandage feeding mechanisms are disclosed, to serially dispense a bandage and simultaneously strip off the liner surrounding the bandage, upon depression of a hand actuated switch. Also disclosed is an improved roll of bandages suitable for use in the bandage dispenser.

Abstract: This invention relates to a dynamic laser cutting apparatus for cutting successively various configurations on a moving feed stock or other moving web or successive sheets. The apparatus includes a control device, which monitors the relative location of the moving feed stock, and controls a scanner to direct a laser beam to cut successively various configurations on the desired relative location of the feed stock. One of the configurations that may be cut with the present invention is sets of successive sheets with index tabs in different locations, from a high-speed moving feed stock, thereby eliminating the need for collating the individual index tab sheets into a set. In order to cut consistently, the control device also monitors the speed of the moving feed stock, and based on the speed of the feed stock, adjusts the power level of the laser to cut consistently on the moving feed stock.
