摘要： Methods, systems, and computer program products determine absorption, specific gravity, and/or porosity of construction materials undergoing analysis corresponding to different measurements of material samples divided from a nullparentnull construction material sample. Dry and wet weights of the samples are obtained under different conditions. In certain embodiments, the material sample is an aggregate that is held in liquid in a volumetric container and the container with the liquid and aggregate is weighed. Another weight of a second sample can be obtained. The second sample is encased in an evacuated vacuum-sealed bag that is opened while immersed in a liquid bath, at which time the weight can be obtained. The weight data can be used to calculate the parameter of interest. Other methods obtain one wet weight of the sample when it is positioned into the liquid bath at atmospheric pressure and the other weight is obtained when the sample is first held in an evacuated state in a sealed (compressible) bag is opened in the liquid bath. The weights can be used to determine the two densities. Other methods employ evacuating a chamber holding a quantity of material sample under water in the container or subcontainer and obtaining weights of the sample under several conditions. Another method increases the pressure in the chamber and obtains weights of the sample under various conditions. Each of the methods determine the material property based on the measured weights. Related devices are also described.

摘要： A device for determining density of a material flowing in a conveying system includes a duct segment in fluid communication with the conveying system. The duct segment is coupled to the conveying system by isolation fittings, which allow the weight of the duct segment to be measured independent of the weight of adjacent portions of the conveying system. Further, a method for determining density of a material flowing in a conveying system includes weighing a duct segment having material free fluid flowing therein. The duct segment having a mixture of material and fluid flowing therein is also weighed. The difference of the two weights is used to determine a linear density of the material.

摘要： The invention suggests the use of microwaves in the spinning industry in order to determine the band mass of an elongated, substantially non-twisted fiber structure. In addition, a method for measuring the sliver mass from the frequency detuning and the damping of resonance signals of a microwave sensor while taking into consideration the moisture of the fiber structure with a computer is suggested. Likewise, a corresponding spinning preparation machine and a laboratory device for measuring the sliver mass are part of the invention. Lastly, a method and a spinning preparation machine for recognizing foreign matter in a moved fiber structure with the aid of microwaves is suggested.
