    摘要： A fluid properties measurement apparatus for use with a conventional high temperature high pressure test cell includes a load cell assembly and a drive motor that drives a rotating shaft magnetically connected to a vane assembly having multiple vane elements, wherein the motor rotates in response to reactive forces of a fluid sample and the load cell assembly measures reactive forces of the sample. In one embodiment, a stepper motor allows for precise shaft rotation. A method of measuring fluid properties includes frequent measurements throughout a complete rotation cycle of a vane assembly within a test cell. A system interference profile is generated which identifies stress variations resulting from various system components throughout the cycle. Measurements of a sample's fluid properties are likewise performed to obtain a profile. Comparison of the sample profile with the interference profile provides fluid properties measurement independent of stress variations resulting from various system components.

    摘要： A medical grade cleansing and numbing agent combination pad is disclosed. An example combination pad includes a pad impregnated with a cleansing agent and a numbing agent each in separate layers. Both the cleansing agent and the numbing agent are released through a same side of the pad without a user having to turn the pad over to apply both the cleansing agent and the numbing agent to a treatment area at substantially the same time. A barrier prevents the numbing agent from contacting the user during application to the treatment area.
