  • Patent number: 10823656
    Abstract: Instrumentation embraces an at least partially automated rotational tapered bearing simulator viscometer having electronic control and/or monitoring that includes task unit electronics, which includes a task unit electronics interface. With or without such electronics, the instrumentation may include a particular component configuration and/or employ at least one particular material. Further feature(s) may be extant.

  • Patent number: 10625233
    Abstract: An active pharmaceutical ingredients (API) or related substance (RS) can be tested for stability by placing the API or RS in an instrument containing a pressure-controllable atmosphere, controlling the pressure of the atmosphere in the instrument for a predetermined time, and evaluating the API or RS for stability. Testing can be carried out also at predetermined temperature(s) and/or under the influence of gaseous trigger(s) and so forth. For instance, an API sample can be placed in a bomb test instrument/reactor, oxygen as a gaseous trigger can be introduced to contact the API sample under constant and/or ramped temperature(s) and elevated pressure(s) for predetermined time(s), and the API sample can be evaluated for stability. An insert carousel may hold a sample of API(s) and/or RS(s) and/or aliquot(s) of sample(s) of API(s) and/or RS(s) for insertion into the bomb test instrument/reactor.

  • Patent number: 10302619
    Abstract: Grease wear test device includes a body in a form of a collar having an outer surface, a first side and an opposing second side, which are open to form a hollow, open channel through the body, which has a center axis, into which opposing vee blocks can be inserted; and perpendicular to the center axis, a pair of opposing holes through and open to the outer surface of the body and the cylindrical inside wall, through which a cylindrical test journal (falex pin) can be inserted for contact in general with opposing vee-shaped channels of the inserted, opposing vee blocks, and for rotation during testing. The device can be used to modify a falex pin and vee block device, to receive and contain a small sample of grease or another organic paste product for testing such as a modified version of an ASTM D2670 test method for measuring wear properties of fluid lubricants (falex pin and vee block method).
