Weighing systems of load-cell electronic type with vibration dampening means

Claim 1

A SYSTEM FOR ACCURATELY WEIGHING A MASS OF MATERIAL WHEREIN SAID MASS AND ITS ENVIRONS ARE SUBJECTED TO UNDESIRABLE VIBRATION, SAID SYSTEM COMPRISING A VESSEL ADAPTED TO RECEIVE THE MATERIAL TO BE WEIGHED, A WEIGH PLATFORM CAPABLE OF IMPARTING A GRAVITATIONAL WEIGHT FORCE SUPPORTING SAID VESSEL, A BASE UNDERLYING AND SUPPORTING SAID PLATFORM AND BEING SUBJECTED TO VIBRATION, MEANS FOR TRANSFORMING SAID GRAVITATIONAL WEIGHT FORCE TO A HYDRAULIC FORCE, SAID MEANS COMPRISING A HYDRAULIC FORCE TRANSMITTER SUPPORTED BY SAID BASE AND BEING DIRECTLY CONNECTED TO SAID WEIGHT PLATFORM, A HYDRAULIC FORCE RECEIVER LOCATED AT A POINT REMOTE FROM THE AREA SUBJECTED TO VIBRATION, SAID RECEIVER BEING SHIELDED FROM SAID VIBRATION, RESILIENT MEANS ESTABLISHING A HYDRAULIC CONNECTION BETWEEN SAID TRANSMITTER AND SAID RECEIVER, FLUID LEVEL COMPENSATING MEANS CONNECTED TO SAID HYDRAULIC CONNECTION FOR REGULATING THE AMOUNT OF FLUID IN THE SYSTEM, STRAIN GAUGE TYPE LOAD CELL MEANS POSITIONED AT SAID VIBRATION-FREE POINT FOR TRANSFORMING SAID HYDRAULIC FORCE TO AN ELECTRONIC SIGNAL, MEANS CONNECTING SAID STRAIN GAUGE LOAD CELL MEANS TO SAID HYDRAULIC FORCE RECEIVER FOR EFFECTING CONVERSION OF A HYDRAULIC FORCE TO AN ELECTRONIC SIGNAL, SIGNAL AMPLIFYING MEANS FOR INTENSIFYING THE LOAD CELL OUTPUT SIGNAL, AND INSTRUMENT MEANS CONNECTED TO SAID SIGNAL AMPLIFIER BEING ACTIVATED BY SAID AMPLIFIED SIGNAL FOR PROVIDING AN ACCURATE INDICATION OF THE TOTAL WEIGHT OF SAID PLATFORM.

Claim 2

A SYSTEM FOR ACCURATELY WEIGHING A MASS OF MATERIAL WHEREIN SAID MASS AND ITS ENVIRONS ARE SUBJECTED TO UNDESIRABLE VIBRATION, SAID SYSTEM COMPRISING A VESSEL ADAPTED TO RECEIVE THE MATERIAL TO BE WEIGHED, A WEIGH PLATFORM CAPABLE OF IMPARTING A GRAVITATIONAL WEIGHT FORCE SUPPORTING SAID VESSEL, A BASE UNDERLYING AND SUPPORTING SAID PLATFORM AND BEING SUBJECTED TO VIBRATION, MEANS FOR TRANSFORMING SAID GRAVITATIONAL WEIGHT FORCE TO A HYDRAULIC FORCE, SAID MEANS COMPRISING A HYDRAULIC FORCE TRANSMITTER SUPPORTED BY SAID BASE AND BEING DIRECTLY CONNECTED TO SAID WEIGHT PLATFORM, A HYDRAULIC FORCE RECEIVER LOCATED AT A POINT REMOTE FROM THE AREA SUBJECTED TO VIBRATION, SAID RECEIVER BEING SHIELDED FROM SAID VIBRATION, RESILIENT MEANS ESTABLISHING A HYDRAULIC CONNECTION BETWEEN SAID TRANSMITTER AND SAID RECEIVER, FLUID LEVEL COMPENSATING MEANS CONNECTED TO SAID HYDRAULIC CONNECTION FOR REGULATING THE AMOUNT OF FLUID IN THE SYSTEM, STRAIN GAUGE TYPE LOAD CELL MEANS POSITIONED AT SAID VIBRATION-FREE POINT FOR TRANSFORMING SAID HYDRAULIC FORCE TO AN ELECTRONIC SIGNAL, MEANS CONNECTING SAID STRAIN GAUGE LOAD CELL MEANS TO SAID HYDRAULIC FORCE RECEIVER FOR EFFECTING CONVERSION OF A HYDRAULIC FORCE TO AN ELECTRONIC SIGNAL, SIGNAL AMPLIFYING MEANS FOR INTENSIFYING THE LOAD CELL OUTPUT SIGNAL, AND INSTRUMENT MEANS CONNECTED TO SAID SIGNAL AMPLIFIER BEING ACTIVATED BY SAID AMPLIFIED SIGNAL FOR PROVIDING AN ACCURATE INDICATION OF THE TOTAL WEIGHT OF SAID PLATFORM.
