Abstract: A lockable enclosure including a safe, a suitcase, a briefcase, and the like has an interior sized to receive articles and an electronic key assembly actuating a cam mechanism upon entry of a preprogrammed entry code. The cam mechanism has a cam that depresses a release lever of the a latch assembly to a position, wherein the latch assembly disengages from the lockable enclosure to allow a door to swing in an open position so as to enable access to the interior of the lockable enclosure.

Abstract: A safe assembly includes a portable lockable enclosure, a mounting plate for securing the lockable enclosure to a stationary surface, and a latching element actuatable from an interior of the safe assembly to detach the lockable enclosure from the mounting plate for further travel or relocation. The latching element has a latch assembly engaging a pair of brackets extending from the mounting plate into the interior of the safe assembly and a release assembly enabling disengagement of the latch assembly.

Abstract: A machine and method of performing a work operation requiring a known or predetermined length of unconsumed web has a cassette containing consumable web material, and the cassette has an indicator for identifying a length of unconsumed web in the cassette. The length of unconsumed web in the cassette is compared to a known or predetermined length of unconsumed web required to perform the work operation, and the operation is performed if the length of unconsumed web in the cassette is at least equal to the required length of unconsumed web. In one embodiment, the indicator takes the form of a potentiometer mounted on an exterior surface of the cassette for electrically indicating the amount of unconsumed web, or a pointer carried by a worm gear rotatably coupled to a spool of the cassette, wherein the pointer moves relative to indicia on the cassette upon rotation of the spool to visually indicate the amount of unconsumed web in the cassette.

Abstract: A sheet material support system includes a floating box having upwardly extending leading edges defining a plane extending parallel to said base in which sheet material is caused to conform to by applying downward pressure to it and causing the sheet material to become tautly drawn over the box upper edges. The system includes a locating block and clamps which allow frames to be located uniformly along X and Y coordinate axes so that successive frames can be loaded in uniform registration in the system.
