TLDR
A positive stirring consistometer cup as discussed by the authors includes a pair of wall blade members having radially inwardly extending blades which cooperate with a paddle to uniformly apply shear throughout a substance to be tested.Abstract:
A positive stirring consistometer cup includes a pair of wall blade members having radially inwardly extending blades which cooperate with radially outwardly extending blades of a paddle to uniformly apply shear throughout a substance to be tested. A split sleeve assembly eliminates an outer dead space, and an enlarged spacer member mounted on the shaft of the paddle eliminates an inner dead space, thereby enhancing the uniformity of the shear throughout the substance. A centralizing assembly centers the stationary paddle while causing a minimum of friction and wear to occur on the shaft of the paddle. In a method of using the positive stirring consistometer cup, the blades of the wall blade members and of the paddle stop in substantially aligned, coplanar relationship to facilitate cleaning of the elements after a test is concluded.read more

Yield point adaptation for rotating viscometers
TL;DR: In this article, a method of measuring yield stress using a standard rotating viscometer modified with a plurality of intermeshing fins such that a standard spring responds to a torque that is related to yield stress and that is imposed by a stressed test material on a portion of the fins connected to the spring.

Variable shear rate, wide dynamic range true indicating viscometer
TL;DR: In this paper, a rotational viscometer is used to measure the viscosity of a liquid at the angular speed at which the shaft is rotated, which is independent of speed.
