摘要： On-line rheological measurements are made utilizing a rheometer of the type in which a first metering pump delivers diverted melt from a process main stream to a capillary passage and a second metering pump returns the diverted melt from the capillary passage to the process main stream and the viscosity of the diverted melt is measured by controlling the rate of flow of the melt to maintain constant the pressure drop between spaced apart locations along the capillary passage and measuring the temperature of the melt in the capillary passage. The measurements may be made while controlling the speed of the second metering pump independent of the speed of the first metering pump to maintain the pressure at the exit of the capillary passage essentially constant. The capillary passage is placed in close proximity to the process main stream for maintaining a relatively short residence time during which the diverted melt resides outside the process main stream so as to attain a relatively quick response to changes in the measured viscosity. The rheometer includes a relatively thin plate interposed between first and second blocks, the plate including a slot establishing a chamber between the first and second blocks for providing the capillary passage.

摘要： Impact testing apparatus in which a weighted dart is dropped from a prescribed height to penetrate a test specimen when traveling at a desired velocity and level of kinetic energy, the acceleration of the dart being assisted by a spring force in the direction of travel so that the prescribed height is maintained at a minimum for a given desired velocity and the dart being guided to the test specimen by a generally tubular guide within which the dart is loosely fitted. A force transducer is located at the tip of the dart for providing impact force information as the tip penetrates the test specimen.

摘要： Disclosed herein is a torsion tube apparatus for making on-line measurements of the viscosity and elasticity of a fluid. The apparatus includes a housing member, an outer cylinder having one end rotatably mounted with respect to the housing member, and a motor for rotating this outer cylinder. An elongated torsion tube is mounted concentrically within and spaced from the outer cylinder and has one end fixed to the housing member, with its other end freely disposed within the cylinder for torsional movement with respect to the fixed end. Therefore, an annular void is defined between the tube and cylinder. Fluid may be introduced through a conduit into the interior of the cylinder for flow therethrough and discharge therefrom, such that rotating motion of the fluid caused by rotation of the cylinder exerts a torsional force directly on the outer surface of the tube. A torsion indicating shaft extends concentrically through the tube, having its one end fixed to the free end of the tube. An indicator is fixed to the other end of the shaft. Accordingly, torsional force on the tube provides the sole source of rotative movement of the shaft that is detected by the indicator. The assembly provides a smooth axial path for the fluid which flows through the annular void between the outer cylinder and tube.

摘要： A rheometer includes a holder assembly for coupling a test specimen to a motor assembly to effect rotational strain in the test specimen while enabling the determination of axial displacement effected by the test specimen normal to the direction of the rotational strain, the holder assembly having a first member coupled to the test specimen, a second member coupled to the motor assembly, and a suspension arrangement coupling the first member with the second member for simultaneous maximum resistance to relative rotational displacement between the first and second members and minimum resistance to relative axial displacement between the first and second members. Information pertaining to the axial displacement, and to the temperature of the test specimen, is obtained through measuring circuits which include sensors placed in moving component parts of the rheometer and is delivered to an external processor through information transmission systems which include an induction arrangement for transmitting the information while maintaining the desired minimum resistance to the relative axial displacement. Power is delivered to the measuring circuits through a power transfer system which includes a similar induction arrangement.

摘要： System and methods are described for dynamically controlling operation of a rheometer. A program is created on a programming interface for executing a test upon a sample in a rheometer by receiving user selections of a plurality of nodes and connections of each node to another node according to directional connection indicators. Nodes indicate steps for performing a test upon a sample or configuring a rheometer for performing a test upon a sample. Scripts are created for generating a sequence of instructions to the rheometer. The scripts include instructions for performing steps indicated by each of the selected nodes and in accordance with the directional connection indicators. Low-level instructions are downloaded from the scripts for execution in the rheometer, and drivers in the rheometer are instructed for performing the downloaded instructions.

摘要： On-line rheological measurements are made on a process flowing material, such as a polymer melt, utilizing a rheometer of the type in which an inlet pump delivers a relatively large volumetric flow of diverted process material from a process main stream to an inlet site located in very close proximity to the entrance of a capillary passage, and a metering pump draws a smaller portion of the volumetric flow of the diverted material from the inlet site through the capillary passage for return to the process main stream. The viscosity of the diverted material is measured as a function of the rate of flow of the material through the capillary passage and the pressure drop between spaced apart locations along the capillary passage. A parallel flow passage has a volumetric flow capacity considerably greater than the volumetric flow capacity of the capillary passage, an inlet placed at the inlet site, in very close proximity with the entrance of the capillary passage, and an outlet placed downstream of the metering pump. A parallel flow pump in the parallel flow passage moves the balance of the volumetric flow of diverted material from the inlet site for return to the process main stream to assure a continuous supply of fresh diverted material at the entrance to the capillary passage.
