Abstract: A method and program product includes establishing a bi-directional communication channel with an operator's filming system. At least one command is communicated to the operator's filming system. The command at least includes instructions for conducting a filming, wherein the instructions are displayable on the operator's filming system. At least a real time stream of the filming is received. At least additional commands are communicated to the operator's filming system during the receiving, wherein the communicating, the receiving and the communicating during the receiving comprise a negative feedback loop during the filming.

Abstract: An apparatus for machining bearing balls has a motor which drives, through an elastic coupling, a gear box connected by a telescoping coupling to a crown gear device. The output of the crown-gearing is applied to a rotatable disk. An electric motor drives a gear pump which has its output connected by an electromagnetic distributor to a hydraulic cylinder adapted to press the rotatable disk against a fixed disk, the balls being circulated between the disk and machine (filed, ground or lapped) therebetween.
