    摘要： A method and an assembly for testing a shipping package are described. The assembly includes a scuff test sub-assembly, a belt burn test sub-assembly, and multiple conveyors positioned between to the sub-assemblies to convey a shipping package through the assembly. The scuff test sub-assembly includes an inclined plane and multiple objects which extend outward from the inclined plane. The belt burn test sub-assembly includes a plate that moves over a portion of one of the conveyors. The plate moves between a first position which obstructs movement of the shipping package but permits movement of the one of the conveyors relative to the shipping package and a second position where movement of the shipping package along the conveyor is not obstructed. At least two of the conveyors meet at a junction to change an orientation of the shipping package as the shipping package is conveyed across the junction.

    摘要： The present invention refers to a measuring device (600) for measuring the fineness and maturity of cotton fibers, such a measuring device (600) comprises a measuring chamber (CM) into which a sample of cotton fibers can be inserted, the measuring chamber (CM) comprises a first base and a second base that are opposite each other and that can be crossed by an air flow entering the measuring chamber (CM) through the first base and exiting from the measuring chamber (CM) through the second base, a supply conduit (619) having an inlet end associable with an air flow source and an outlet end associated with the first base of the measuring chamber, a flow regulator (611) arranged along the supply conduit (609) between its inlet and outlet ends, a first pressure sensor (612) for detecting the air pressure that is arranged along the supply conduit (609) upstream of the flow regulator (611), a second pressure sensor (613) for detecting the air pressure that is arranged along the supply conduit (609) downstream of the flow regulator (611) and upstream of the first base of the measuring chamber (CM), an electronic proportional pressure regulator (614) arranged along the supply conduit upstream of the first pressure sensor (612) for regulating the air pressure in the supply conduit (609), and an electronic processing and control unit (615) associated with the first sensor (612), with the second sensor (613) and with the electronic proportional pressure regulator (614) and that is programmed to control the electronic proportional pressure regulator (614) as a function of the detections of the first sensor (612) and of the second sensor (613) or of the second sensor (613) alternatively and respectively to keep the difference between the air pressure upstream and downstream of the flow regulator (611) or the air pressure entering the measuring chamber (CM) substantially constant and equal to a predeterminable value.

    摘要： The subject matter described herein includes methods, systems, and computer readable media for dual resonance frequency enhanced electrostatic force microscopy. One method includes applying an alternating current (AC) bias and a direct current (DC) bias to an atomic force microscopy cantilever, wherein the AC bias has a frequency greater than a fundamental resonance frequency of the cantilever. The method further includes mechanically vibrating the cantilever at a frequency different from the frequency of the AC bias. The method further includes physically and electrostatically scanning a sample in the same pass using the cantilever while vibrating the cantilever and applying the AC and DC biases to the cantilever, and generating a topology image of the sample from the physical scanning and an electrostatic image of charged material under or on a surface of the sample from the electrostatic scanning.

    摘要： An analytical method and container for measuring the soap content in black liquor. The method includes: a first step where a defined amount of black liquor is arranged in the container, a second step where the black liquor is centrifuged and a soap concentrate is gathered in the upper part of the container, a third step where the amount of soap concentrate is determined, and a fourth step where the soap content is calculated. By centrifuging the black liquor soap concentrated with a soap content of 58-62% is obtained, which enables measurement of the dry matter with an accuracy of ±2% within a very short time period. The container includes a neck with scale marks and a lower part. In one embodiment, the analytical method includes a fifth step where a modification of the calculated soap content is made with consideration to the density of the black liquor.
