Abstract: Hockey sticks or other tubular shafts have historically been cut using a hack saw with the shaft resting on the lip of a garbage can resulting in slow and inaccurate cuts. A new device for cutting a shaft comprises a holder for receiving the shaft, and an arm rotatably mounted at an end of the holder. The holder includes an internal passage, sized to receive the shaft, which extends outwardly through an opening at the end of the internal passage. A set of jaws are mounted on the rotating arm, each jaw includes a saw blade extending across the opening perpendicular to the shaft. The jaws are spring biased together at a first end for engaging the shaft, whereby relative rotation of the arm and the holder results in the saw blades sawing the end of the shaft off with high precision.

Abstract: Steel reinforced tire fabrics are cut with long rigid bar blades, circular disc blades and disc and anvil blades. All of these blades may have an open relatively deep slot spaced close to the cutting edge that creates a resilient cantilevered spring element that includes the cutting edge. In response to cutting forces, the spring element will deflect and form a concave crossover area that improves cutting. A supporting material, particularly a precompressed supporting material, such as a precompressed or stretched polyurethane strip may be inserted into the slot. The supporting material limits or reduces the deflection of the spring element so that the yield strength of the spring element is not exceeded and it returns to its original position when the forces are removed. A precompressed supporting material exerts an outward force on the spring element. A polyurethane strip may be precompressed by stretching it before it is inserted into the slot.

Abstract: A shape memory alloy (SMA) actuator predeformed in compression actuates a cable cutter mechanism. A cable or other item to be cut is placed between an anvil and a movable blade affixed to the SMA element. The SMA element is heated by an electrical resistance heater to cause it to return to its undeformed elongated state, thereby moving the blade against the anvil to compress and sever the cable or other item. Ones of the shape memory alloy actuator have a plurality of parallelly arranged SMA elements, every other one of which is predeformed in compression and intermediate ones of which are predeformed in tension. The elements are coupled end-to-end so that, when they are heated to cause them to return to their undeformed states, their respective elongations and shrinkages combine at the output to produce an actuation that is the cumulation in the same direction of the changes of all the elements. The plurality of elements may be in a side-by-side or concentric arrangement.
