Abstract: An apparatus and method for aligning an internal combustion engine block to be bored by a vertically movable boring tool so that the center of rotation of a crankshaft to be mounted within the engine block is perpendicular to the direction of vertical movement of the tool.

Abstract: A strip which will form a rigid shoe stiffener, such as a shoe shank, is applied to the surface of a shoe to be stiffened, such as to the bottom of an insole. The shank strip is flexible and includes a carrier sleeve or envelope containing a plurality of fiberglass strands in thermosetting plastic matrix. After the shank strip is in place on the insole, the matrix is activated by exposing it to an external stimulus such as radiant heat which is applied locally to the shank strip. Curing takes place in situ on the insole bottom. The carrier sleeve is formed in a manner which provides control over the shape of the cured stiffener as well as a means to facilitate handling of the shank strip.

The shank strip is flexible and includes a carrier sleeve which contains a plurality of fiberglass strands in a thermosetting plastic matrix. After the shank strip is in place, the matrix is activated by exposing it to an external stimulus such as heat or radiation. Heat can be applied locally to the shank strip and curing takes place directly on the insole bottom. The thermosetting resin can polymerize with or without an exothermic reaction. Preferably, sufficient heat is developed from exothermic heat or from the energy source and directed to melt the carrier sleeve to fuse it with the resin and to effect a bond to the insole for forming a unitary and rigid shank attached firmly to the insole bottom. The shank strip may be cut from a "rope" which may be wound onto a reel for storage and to facilitate continuous paying out of the rope to enable a shank length to be severed and applied to the insole bottom.

Abstract: A damper for use with work arbors supported at only one end is disclosed which acts to reduce harmonic vibration and chatter as the arbor rotates and a cutting tool operates on the workpiece. The damper consists of a damping collar, with an interior radius greater than the exterior radius of an associated spacer, which freely rotates on that spacer such that the collar rotates independently of the work arbor at a speed of about 66% of the arbor's speed and acts to suppress undesirable chatter, and harmonic vibrations.
