4783904

A bandsaw blade including a continuous loop of hardened tempered bandsaw steel having carbide-tipped teeth arranged in pairs, each pair including a high tooth and a low tooth shaped to provide triple-chip cutting action and ground to provide radial and tangential relief angles on side surfaces of each saw tooth to reduce blade vibration during cutting. The teeth are secured to the blade body by brazing with a solder which ineludes a discrete layer of a ductile metal which absorbs forces induced in the brazing zone under dynamic load conditions.

AUTOMATIC ASSEMBLY APPARATUS Akira Kimura, Tokyo, Japan assigned to Sony Corporation An automatic assembly apparatus has a first conveyor for transporting trays carrying parts to be assembled, a second conveyor for transporting pallets on which the parts are to be assembled and which extends parallel to the first conveyor, a stocking station positioned between the first and second conveyors and at which a plurality of the trays can be accommodated, a working station adjacent to the second conveyor, a pusher arm for moving trays from the first conveyor to the stocking station, and a root mounted between the first and second conveyors forcarrying the trays from the stocking station to parts supplying stations adjacent the working station, and for assembling, on pallets transported to and from the working station by the second conveyor, parts removed by the robot from trays situated at the parts supplying stations, whereby a plurality of parts can be assemled by a single robot and it is possible to automatically and efficiently assemble the parts even in cases of relatively small scale production.

4784543 QUICK CHANGE

TOOL

HOLDER

James L Mitchell, Robert W Britzke assigned to Rogers Tool Works Inc A quick change tool holder having a cutting head on which a cutting member is attached for attachment to a shank. A lockpin/locknut arrangement provides for quick and safe removal of the cutting head from the shank. The lockpin has radial projections that rotate in response to manual rotation of the lockpin in and out of recesses contained in the opening of the locknut. The lockpin is secured within a bore in the cutting head and extends out of that bore into a bore in the shank in which bore the locknut is secured. A spring and plunger combination is located in the bore of the shank in order to urge the cutting head away from the shank when the radial projections are not within the recesses of the locknut. The shank and the cutting head have corresponding mating teeth in order to prevent rotation of the cutting head relative to the shank when the cutting head and shank are attached.
