Abstract: Prior applications disclosed power supply transmission voltage resulting in reduced line losses, with further energy conservation via luminous intensity control (dimming) of lamp(s) including LEDs.

Abstract: A method and machine for cutting precise sized mults from billets of a nickel based alloy, which involves rotating each billet by means of a chuck while the billet is supported on rollers coaxially in the chuck; providing a track parallel to the billet axis and a carrier movable along the track, on which carrier is disposed a rotatable saw movable toward and from the axis of the billet to effect cutting, the location of the saw cut being determined by a computer programmed to control a servo motor acting on a screw coupled to the carrier by nut means, the computer being provided not only with basic information as to the density and stated diameter of the billet, but with information as to variations in such diameter, detected by sensor means provided on the carrier in proximity with the saw, and transmitted to the computer.
