Abstract: In this system an unbalancing force, as set by an unbalance load injection device integrated into a work piece balancing machine and its balance computer, is injected into an injection planethrough an operating portion of the machine. This injected load is in effect transferred by computation to a calibrating plane of a known standard or a masterwork part loaded into and rotatably driven by the balancing machine. The values of the unbalancing force as generated by the unbalance injecting device and by calculation into the rotating master are sensed by synchronizer and vibration pick-ups. Data reflective of the injected imbalance are furnished to the balance computer for the calibration thereof. The principle of this self-calibration is to use a workpiece drive spindle and unbalance injector device that can introduce a known unbalance, set by adjusting the unbalance injector device to inject a predetermined load at a known angle into the master to effect master unbalance.

Abstract: Machine and method for applying an anaerobic sealant and locking material into a workpiece bore in which an outwardly flaring cup mounted onto a rotatable anaerobic material reservoir and spin cup drive having a truncated conical wall with openings therein to feed the anaerobic material into the flaring spin cup in response to the centrifugals on the material as the reservoir and spin cup is rotatably driven. The anaerobic material will be spun from the cup in a controlled manner so that an annular layer of anaerobic material is applied onto the bore wall. A closure member can be subsequently inserted into the bore being sealed and permanently retained therein by the material. In a preferred method, the reservoir and spin cup assembly is moved between a retracted material load position and an extended material apply position.
