Abstract: The spindle on which the wheelhead rotates is mounted within a spindle housing which, in turn, is mounted by a bearing at one end in a pivotally mounted housing. A pair of hydraulic cylinders engage the opposite end of the spindle housing and are actuated during a cutting stroke so as to impose a force on the spindle housing to effect a lateral displacement of the spindle housing in a plane common to the spindle axis and the pivot axis of the housing. The lateral deflection, in turn, causes a lateral deflection of the wheelhead thereby controlling the lateral deviation of the wheelhead relative to the true cutting plane during the cutting stroke. A sensor is provided between the housing and the wheelhead to sense and control deviations of the wheelhead from the true cutting plane. The arrangement may also be used for saws with wheelheads which are horizontally mounted for the cutting of vertically mounted ingots.

Abstract: A steel rule first die is made by mounting steel rule elements, and other shearing elements if desired, in a die block in known manner. A punch die blank is mounted on a support having means for aligning the blank with such shearing elements. One or more layers of adhesive tape of predetermined thickness are applied to the shearing side face of the shearing elements to define a clearance-producing layer thereon. Foamed plastic blocks are adhered to the punch blank so as to form defined areas on its face opposite the shearing elements of the first die, and an adherent impressionable soft layer of hardenable resin is applied to such defined areas. The first die is then assembled in aligned relation with the punch die blank, with its shearing elements impressed deeply in the soft resin layer so as to form wide edge faces in such layer against the clearance-producing layer of tape on the shearing side faces of the shearing elements.

Abstract: A cutter/scraper is disclosed having a flexible supporting structure. The support structure incorporates a frangible guard, the latter being reusable to cover the cutting edge subsequent to separation from the support handle. Handle flexibility permits improved scraping operation, and easier gripping is afforded for the cutter. The integral blade guard forms part of the packaging, and permits the visibility of the cutting edge while safely protecting from the effects thereof. The apparatus is formed of a single, inexpensive molded piece of plastic, thereby making the cutter/scraper disposable after having served its purpose.

Abstract: A fishing lure having a spoon-shaped blade with a first attachment location for a fishing line and a second attachment location spaced from the first location includes an offset tail in the form of an elongated stiff member having a first end firmly attached to the blade at the second attachment location and a second end carrying a loosely attached hook. The stiff member extends away from the blade in a direction such that the center of gravity of the member is offset with respect to an extension of a line between the first attachment point and the second attachment point. The offset tail causes the lure to trail through the water in a sinuous path with realistic short side-to-side darting motions. The stiff member may be made of wire, with beads of brass, or other material heavier than water, strung along the wire, preferably in order of increasing size from the first end to the second end.
