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.

Abstract: This invention relates to an instrument of a type known variously a a biopsy needle or cannula and used to gather tissue, and particularly soft tissue such as bone marrow, from living persons or animals for pathological study. The instrument retains a gathered tissue specimen by closing the end of a hollow member while the member is in the gathering position, and more particularly by deforming a flexible portion of the member. A pair of members are employed, one moving within the other. By a particular cooperation between the members, a flexible portion of the inner member is displaced or deformed to occlude an open, tissue receiving end thereof and thereby capture tissue and retain it against loss on removal of the instrument from the body of tissue into which it has been thrust.

Abstract: Excess hoof growth is removed from the hooves of dairy cows and other hooved animals by use of a power tool equipped with an apertured cutter disk whose upper face can be viewed by the operator so as to see an image of the field or area of cut through the rapidly rotating apertures and to thereby control the depth of cut. Circular series of open and preferably rectangular apertures and of cutting blades preferably associated with the apertures are advantageously canted diagonally from the radial to facilitate the making of very shallow cuts. The power tool is preferably a standard right-angle type normally used with grinder disks.

Abstract: A combination slicing and storing device for food products in block form wherein the food product is caused to descend by gravity within a tubular member mounted on a base such that a portion of the food product projects through an opening in the base and is supported on a recessed food support provided on a slice holder plate. The slice holder plate is operatively associated with a trigger member mounted on the base, being adapted for sliding movement with respect to the base upon manual actuation of the trigger member by a user of the device. Actuation of the trigger member causes a cutting member on the slice holder plate to be drawn through the projecting portion of food so as to create a slice of food product of uniform thickness. The slice is allowed to fall away from the device and onto a serving dish or plate by virtue of the fact that the food support has moved out of position beneath the food product.

Abstract: Apparatus for removing the internal bead from a polyethylene pipe joint, that has been fabricated by the fusion process, comprising a torque tube of sufficient length to reach from the open end of the pipe to the joint from which the internal bead is to be removed. At the distal end of the torque tube is a cutter head, which includes a blade set at the proper angle to contact the inner surface of the pipe. This blade is mounted on an arm which has a hub to which the torque tube can be attached. A support frame has two legs and is pivoted to the cutter arm in such a way that when the torque tube and cutter arm are turned counterclockwise, the blade is pulled away from contact with the internal surface of the pipe. When the torque tube and arm are turned clockwise, the arm rotates about its pivot on the support frame and comes into a position such that the blade is opposite the support legs, and locks against a stop pin. The cutter blade in that position is pressed against the inner surface of the pipe.
