Abstract: A Z-axis measurement fixture used for testing whether a chemical reagent test slide exhibits Z-axis variability, which may affect measurements performed by an automated chemical analyzer using such test slides, includes a planar main body that holds three stainless steel balls, each ball having a known and calibrated diameter. Portions of the stainless steel balls extend outwardly from the top wall and the bottom wall of the planar main body. A chemical reagent test slide is placed on the fixture to rest on and be supported at three points by the portions of the stainless steel balls which project outwardly from the top wall of the planar main body. The fixture is placed on the surface of a gauge block of an optical measurement system such that the lower portions of the three stainless steel balls will rest on the gauge block of the optical measurement system.

Abstract: Techniques are disclosed for generating and dynamically updating an experience score for a client, where the experience score operates as a quantitative indicator describing a relationship between the client and an entity. The experience score is used to modify subsequent interactions the client has with the entity. Sentiment data detailing the relationship between the client and the entity is acquired. The sentiment data is received from different types of interactions the client had relative to the entity. NLP is used to provide structure to the sentiment data, resulting in an initial set of scoring data being made available. That scoring data is normalized. After normalizing the scoring data, weighting factors are applied to the scoring data to generate weighted scores. The experience score is then generated by aggregating the weighted scores. The experience score is used to then modify a subsequent interaction the client has with the entity.

Abstract: Disclosed herein are methods, devices, and systems for effectively separating carbonate gangue from bastnaesite without sacrificing significant REO grade or recovery. In some embodiments, centrifugal concentrators may beneficiate Ultra-Fine (UF) bastnaesite and calcite bearing flotation concentrates. The disclosed methods, devices, and systems can achieve initial gravity REO recoveries exceeding 90% while rejecting on the order of 25% to 35% of the total calcium from an assortment of rougher and cleaner flotation concentrates. Addition of stages of cleaner UF Falcon gravity separation may be operated in an open circuit configuration, from an original fine feed of 35 microns containing 50.5% REO and 5.5% Ca, to upgrade up to approximately 59% REO and 2.0% calcium.
