A reconditioning device includes: a first shearing plate; a second shearing plate; and a housing. The housing includes: a first member configured to hold the first shearing plate and comprising an input for receiving a material; a second member connected to the first member to form an inner cavity, a portion of the inner cavity is located in a gap between the first shearing plate and the second shearing plate; and an output member connected to a pipeline of a production applicator and configured to output the material subsequent to shearing. The shaft extends through the second member, is connected to the second shearing plate, and is configured to be rotated to shear the material disposed in the gap between the first shearing plate and the second shearing plate.

An extruder includes a cylinder 2 and a die 5 attached to the cylinder 2. The die 5 has a resin flow path portion 22 to which a molten resin is supplied from the cylinder 2 and a hole 21 which is connected to the resin flow path portion 22 and from which the molten resin is discharged. The extruder further includes a pressure measurement unit 31 configured to measure a pressure of the molten resin in the cylinder 2 or the die 5 and a calculation unit configured to calculate a viscosity of the molten resin based on a measured value of the pressure measurement unit 31.

A fluid monitoring and management device that includes a housing with a fluid passageway. The fluid monitoring and management device further includes a fluid property sensor with a sensing element in the fluid passageway. A valve is in the fluid passageway of the fluid monitoring and management device. A removable bottle mount is aligned with the valve to be selectively in fluid communication with the fluid passageway.

A device for measuring the flow rate and viscosity of ink sent to a print head of an ink jet printer comprises: a restriction of the diameter of a conduit for the flow of ink arranged in the path thereof defined by the conduit; a sensor for measuring the pressure difference (P.sub.in-P.sub.out) between the pressure of fluid upstream of the restriction and the pressure of ink downstream of the restriction; a viscous leak, creating a pressure drop by friction loss, the viscous leak being in series with the restriction, in the path of the ink defined by the conduit; a sensor for measuring the pressure difference (P.sub.inV-P.sub.outV) between the pressure of fluid upstream of the viscous leak and the pressure of ink downstream of the viscous leak; and a circuit for calculating the flow rate and viscosity of ink as a function of: (P.sub.in-P.sub.ou)t and (P.sub.inV-P.sub.outV).

Evaluating surfactants for use in downhole applications, especially surfactants with similar surface tension or interfacial tension values and wetting properties, may be achieved with a sensitive column test using a non-uniform particulate media therein. An exemplary method may include providing a column containing two types of particles that differ by at least one of: a mean particle diameter, a sphericity, and a chemical composition. Surfactant samples may be individually tested by passing the sample through the column followed by a displacement fluid, typically an oleaginous. The displacement rate and volume of the surfactant sample may be used to assess the surfactant's suitability for downhole applications.
