Method and apparatus for measuring physical properties of matter

A system is described for determining the physical properties of a sample of matter, including the volume, mass and density of the sample. The system uses a single chamber (12), wherein the sample is weighed by a weighing device (14). The chamber is pressurized by a gas of known properties and purity for which the thermodynamic pressure-density-temperature surface is known. As the pressure regulator (40) controls the chamber pressure. As the pressure inside the chamber is changed by regulating the pressure, the apparent weight of the sample, the fluid temperature (36), and the fluid pressure (32) are measured and recorded. A significant feature of the system is the recording of a plurality of weight and fluid density measurements as the pressure in the chamber is changed. The plurality of fluid density measurements results in an improved statistical measure of the sample density. Additionally, the determination of weight at many different densities captures any possible non-linear effects as would be evidenced in compressible media. Thus, the method and apparatus may be used to determine the compressibility or porosity of an object.

Hydraulic control system for weighing and two-way valve therefor

A motion control system for hydraulically operated lifting devices. The system provides for the dynamic weighing of a loaded container by controllably directing hydraulic flow through a bypass chamber (51) of a two-way valve (42). An analog output signal is generated by a hydraulic pressure transducer (53) fluidly communicating with the two-way valve or by a tensiometer (24) mounted on the arms of the lifting device (14). The two-way valve (42) further provides a second bypass chamber (54) which receives fluid under gravity from the lift circuit line (40) of the hydraulic cylinder (18) for controllably lowering the lifting device (14). The pressure transducer (53) or tensiometer (24) generate an analog signal proportionate to the weight being lowered and whereby the hydraulic fluid is returned to the reservoir of the hydraulic system independently and downstream of the main operating valve (33).

WEIGHING DEVICE FOR PARTICULARLY MEASURING WITH HIGH PRECISION OF LARGE WEIGHT

Weighing device, intended in particular to be installed on a vehicle in order to weigh the load thereof

The device is installed on the chassis 1 of an agrarian trailer, connected to a bucket 3 by an articulation 4 which has vertical play. Three lifters 8 are mounted beneath the bucket 3 and connected via individual circuits 16 to a hydraulic station 17.

A manometer 84 graduated in weight exposed to the pressure between the pump and the piston gives an indication representing the weight of the load. Use to avoid the weighing taking place with the lifters at their end stops, which would falsify the measurement.
