An adhesive tape dispenser is provided that includes a lower housing (200) that includes a pivot post (212) substantially perpendicular to a back wall of the lower housing, a back plate (230) assembly that includes a push button (244) assembly, a tape unwind spool (234), a lower pin (236), an upper pin (238), and a wedge (240) that is slideably engaged with the lower housing, and a blade assembly unit (260) that includes a cutter arm (262). The cutter arm includes a cutting blade (264) and a semi -tubular opening (270) that slideably engages the pivot post (212) of the lower housing. The cutter arm also includes an outer edge that guides along the wedge and lifts the forward end of the cutter arm (that includes the cutting blade) when the back plate assembly is urged forward by pressing the push button assembly forward. When the push button assembly is urged rearward, a lever arm and a lever foot (268) engage the upper and lower pin (238, 236) of the back plate assembly forcing the cutter arm to pivot so that the front of the cutter arm is forced downward allowing the cutting blade to cut the adhesive tape.

A multi-chambered inflatable member formed by connecting the perimeters of two polymeric film layers includes a seal line spaced from the perimeter that interconnects the two film layers to form a perimeter inflatable channel along a portion of the perimeter. A plurality of inflatable cells extend between opposing portions of the inflatable channel and are in communication with one of the opposing portions of the inflatable channel. A check valve communicates with the inflatable channel to inflate the inflatable member. Articles being shipped or stored in a container can be placed between two or more inflatable members, the perimeter inflatable channels of which provide perimeter protection between the article and the container.

An accessing step, mounted on a vehicle having a bumper attached to the vehicle frame, comprises a step part and a mount assembly fixedly supported on the bumper and frame, mounting the step part for swinging movement from a first operative position in which the step part extends generally horizontally to a retracted second position pivoted upwardly to lie generally vertically adjacent the bumper. The mount assembly incorporates a lock device automatically operative between the mount assembly and step part for releasably locking the step part in the second position and automatically locking up to block the step part from downwardly swinging beyond a substantially horizontal position, while permitting the step part to be swung upwardly.

A chuck for gripping workpieces to be machined has a chuck body with a workpiece support surface for supporting a workpiece to be machined. Generally radially movable centering and gripping collet fingers are concentrically supported by the chuck body. An inflatable bladder is further mounted on the chuck body in generally concentric relationship with the fingers. Control mechanism is provided for initially radially moving the centering fingers to cause them to move radially and center said workpiece, and then supplies a fluid under pressure to inflate the bladder and move the gripping fingers generally radially to fully grip the centered workpiece.

A device for cutting media is provided. The device includes a cover having a sidewall extending therefrom; a guide disposed substantially beneath the cover and comprising a blade; an actuating mechanism disposed in at least one of the cover and the guide; and an actuating wall disposed between the cover and the guide. Engagement of the actuating mechanism creates a cutting action between the blade and the actuating wall.
