Abstract:
There is disclosed a method for thermally processing a textile structure in which the structure is run through a treatment zone in which the structure temperature is changed by heat exchange by contact with a flowing liquid.
Abstract:
A method for thermally processing a textile thread in which the thread is run through a treatment zone. In this treatment zone, the thread temperature is changed by heat exchange, particularly by contact with a flowing liquid. The thread is rotating about its axis while in contact with the liquid.
Abstract:
A rheometer includes a drive shaft, a drag cup motor for rotating the drive shaft, a first measuring object supported by the drive shaft, a second measuring object, a linear position sensor, and processing and control electronics. The linear position sensor includes a target (e.g., an aluminum target) mounted to the drive shaft, and a pair of coils. The linear position sensor is configured to measure thermal expansion of the drive shaft based on a change in impedance of the coils resulting from a displacement of the target relative to the coils. The processing and control electronics are in communication with the coils and are configured to adjust a position of one of the measuring objects relative to the other based on a change in impedance of the coils resulting from a displacement of the target relative to the coils, thereby to maintain a substantially constant measurement gap therebetween.
Abstract:
An optical rheometer system includes a rheometer chamber that can retain a fluid sample to be measured. A light source is provided that creates a light beam incident on the fluid sample. A Peltier heating plate is provided that has a channel region located within the plate. The channel region is configured to substantially transmit a light beam emitted from the light source and incident on the Peltier heating plate. In one embodiment, a rotating optical plate is provided opposed to a first surface of the Peltier plate. The rotating optical plate is substantially transparent such that light from a light beam emerging from the channel region of the Peltier plate can pass through the optical plate and be recorded at a detector. Peltier elements in the Peltier heating plate are arranged to provide uniform heating of sample fluid located on the first surface of the Peltier heating plate. The Peltier elements are further arranged to permit light to pass through the channel substantially unattenuated.

Abstract:
A rotary rheometer having a an upper heating/cooling assembly and a lower heating/cooling assembly located opposite one another opposite a sample gap. The lower heating/cooling assembly may comprise a Peltier heater and the upper heating/cooling assembly preferably comprises a heating element that mates with a heat spreader for heating and cooling the area above the sample and providing more uniform heating and cooling across the sample gap while also minimizing any chimney effect within the rheometer and/or providing heating/cooling capability that is insensitive to changes in the gap between an upper geometry and the lower heating/cooling assembly. The upper heating/cooling assembly may further comprise a cooling channel for cooling the upper heating/cooling assembly.
