Abstract: In an automated quarry operation an unmanned high pressure computer controlled liquid jet cutting system particularly adopted for cutting granite on-site with device for automatically and safely shutting off the operation upon encountering unforeseen, unusual or abnormal technical problems and circumstances such as unworkable hard spots, unusual water pressure etc. The system also includes automatic communication of the status of the system. The system includes a power unit, a balanced oscillator, a communication interface, a plurality of sensors and transducers, an optional mobile system, multiple intensifiers, one or more nozzles with diamond or sapphire orifice and a micro-controller with a control panel for programming and controlling rise and fall, indexer and oscillator system.

Abstract: A coefficient generator, data processing system and method of data reduction in correspondence with multiple-term parametric relationships, and particularly provides for data reduction in correspondence with approximative descriptions which include multiple dependent-variable terms whose higher order derivatives do not vanish. Forms of inverse of deviation variations are implemented to provide weighting which will correct for nonlinear function variations. The forms of inverse deviation weighting are implemented for representing forms of residual weighting and forms of implied squared residual weighting. Represented phases of function similation establish adept equations and implement forms of data processing and representing. Adept data processors correspondingly provide for characterizing approximating relationships in correspondence with provided data.
