Piston Cylinder (Extrusion). Pressure-driven piston cylinder capillary viscometers, ie, extmsion rheometers (Fig. 25), are used primarily to measure the melt viscosity of polymers and other viscous materials (21,47,49,50). A reservoir is connected to a capillary tube, and molten polymer or another material is extmded through the capillary by means of a piston to which a constant force is appHed. Viscosity can be determined from the volumetric flow rate and the pressure drop along the capillary. The basic method and test conditions for a number of thermoplastics are described in ASTM D1238. Melt viscoelasticity can influence the results (160). 

A flow system has been designed to pump fluid through the flow cell. A piston-cylinder arrangement is used as a pump-like" device by... 

Crystallization of ECSCs was isothermally carried out under high pressure using a piston cylinder high pressure cell with diamond window (PCDW) originally made by us. The formation of isolated ECSCs was confirmed by means of transmission electron microscopy (TEM).

Friction force measurements at Skega AB were carried out by the following procedure. A piston/cylinder type of test ring was used. The O-ring being tested was greatly stretched over the piston and fitted into the seal groove. The cylinder was carefully wiped and dried with a clean cloth before the piston was put into the... 

The reduction of the vehicle industry s share is mainly a result of the omission of engine components with large added value (e.g., crankshafts, pistons, cylinder heads and bearings).

After the second half of the twentieth century, the performances of high-pressure devices began to be improved. The piston-cylinder device was modified by...
