Abstract: A tamper-evident closure for a container includes a straw having an outer edge with an outwardly extending projection. The closure includes a cap with a rib. A tamper-evident tab extends from the rib. The tab has an inwardly extending lug configured to engage with the outwardly extending projection of the straw as the cap rotates relative to the straw. The tab has a hinge coupled with the rib. The hinge is configured to rotate the tab outwardly relative to the rib. The tab also has a foldable portion configured to fold to provide a visual indication when the cap is an unsealed configuration.

Abstract: Disclosed is a multiple purpose connectable member. The connectable member may be used and operated to seal or close a container. The connectable member may further be operated to connect a plurality of the connectable members together. A plurality of the connectable members may be connected in various combinations and/or geometries.

Abstract: A viscometer including a thermal block, a thermo device to control temperature of the thermal block, a temperature sensor to sense temperature of the thermal block, a capillary tube embedded in the thermal block such that the capillary tube is in thermal contact with the thermal block, an entrance tube connected to the capillary tube and embedded in the thermal block, a velocity tube connected to the capillary tube and embedded in the thermal block and at least two flow sensors aligned along the velocity tube adapted to measure velocity of the test specimen in the velocity tube.

Abstract: The invention relates to a liquid removal apparatus comprising a body for disposal in a mixture of particulate material and a liquid, comprising an inlet adapted to allow entry of substantially only a liquid, and conduit means in liquid communication with the inlet for entrainment of liquid away from the inlet. The inlet comprises a releasable end cap at an end thereof remote from the conduit means that is releasable by means of the conduit means.

Abstract: The invention relates to a liquid removal apparatus comprising a body 1 for disposed in a mixture of particulate material and a liquid, comprising an inlet 2 adapted to allow entry of substantially only a liquid 3, and conduit means 4 in liquid communication with the inlet 2 for entrainment of liquid 3 away from the inlet 2.
