Disclosed systems provide cost effective dispensers of construction sealant, sausage tubes and other products having varied and even unknown levels of viscosity. A variable ratio drive cam pivots in response to the trigger tension caused by the viscosity of the material to be dispensed. In a relative high force mode, encountered with high viscosity payloads, the drive cam slightly pivots, keeping the distance traveled by the drive rod relatively small in response to a pull of the trigger. This results in a relatively high thrust ratio. Conversely, in dispensing a product with a relatively low viscosity, the drive cam pivots by a greater degree, causing a longer movement of the drive rod in response to the distance traveled by the trigger resulting in a lower thrust ratio. The system works well in caulking guns, bulk loading tools and multi tube tools, such that multiple tools are not required.

An apparatus for forming a wave form for a stent from a wire includes a pair of tension wires configured to rotate about an axis. The tension wires and axis are substantially orthogonal to the stent wire disposed in a gap between the tension wires. When the tension wires are rotated, a bend is formed in the portion of the stent wire disposed between the tension wires. The tension wires may be controlled such that the axis of rotation is aligned with the particular tension wire around which the stent wire is to be bent for each particular bend formed in the stent wire, thereby preventing the particular tension wire from translating during rotation such that the tension wire behaves like a rotary pipe bending die around which the stent wire is bent. A feed assembly feeds the stent wire into the forming area between the tension wires.

A caulking gun for dispensing caulking material from a standard caulk tube. The gun is fabricated in three basic parts; a trigger assembly, a trigger housing and a barrel cage for holding the tube. The facing portions of the barrel cage and trigger housing is provided with a mating configuration which enables the gun to be easily assembled for use and easily disassembled for storage in a toolbox. A novel drip/no drip feature is provided wherein a cam actuator conveniently positioned on the trigger housing enables an operator to select between no drip operation or drip type operation when caulking material and application requirements warrant such. A thumb release mechanism is provided on the rear of the trigger housing so the operator can release the driving rod for insertion of another tube of caulk when the unit has been placed in the drip position.
