A mortising machine having a mortising tool which is designed to oscillate on an elliptical path; the mortising tool is supported on a carrier shaft which is eccentric to a motor drive shaft; the invention concerns the eccentric support for the support shaft and the elements that attach the mortising tools to the carrier shaft, in particular a sleeve is supported on its exterior and is rotated concentrically with the motor shaft, the sleeve has an eccentric opening which rotatably receives another sleeve also having an eccentric opening in it and the carrier shaft is carried in the latter opening.

A modular two-part welding and processing platform is described. A cart section is capable of rotating around objects such as pipes and cylinders, or of linear travel along plates or the like. This cart section reversibly couples to a processing section supplied for instance with welding apparatus, painting apparatus, cleaning means, analysis means or the like. By means of this two-part device, work pieces can be cleaned, welded, and inspected quickly and accurately. Special marks may be provided on the work piece which in conjunction with sensors and motoring means on the cart, allow for precise positioning of the process head with respect to the work.

The invention provides a novel machining tool suitable for machining, e.g., lathing, of a workpiece made from a difficult-to-machine material such as fully sintered ceramics and quench-hardened high-chromium cast irons. The machining tool has a conically pointed cutting chip of a cemented metal carbide and provided with a round-bottom groove of a 0.2-0.5 mm radius of curvature running with an inclination angle of 15-60null relative to the cutting face of the chip. The invention also provides a machining method for a workpiece of a difficult-to-machine material by using the above-mentioned machining tool, in which ultrasonic vibrations are applied to the tool in the cutting direction so that abrasive wearing of the flank surface can be decreased.

1,002,496. Change speed gear. BISHOP, EAVES & SONS Ltd. June 29, 1964 [April 10, 1963], No. 14257/63. Heading F2D. [Also in Division B3] The spindles of a drilling, tapping, milling, boring or like machine tool are driven by an electric motor 24 through gears which comprise a fast and slow forward and reverse drive. Shaft 170 is driven at a slow speed in one direction through gears 184, 186, clutch 190, gears 188, 194, clutch 196, and gears 200, 202, and it is driven at a slow speed in the opposite direction through the gears 184, 186, clutch 190, gears 188, 194, clutch 210 and gears 216, 202. For a fast speed drive in either of the two directions, clutch 190 is disconnected and clutch 208 is connected, thus driving through gears 212, 214. The clutches are electrically controlled.
