A blend valve assembly including a plurality of ports, a stator having at least one fluid flow path defined therein that extends between at least one port of the plurality of ports in communication with the primary fluid media and at least one port of the plurality of ports in communication with an intake of a testing device, and a rotor comprising at least one fluid flow path defined therein. The rotor is movable between a series of positions such that the blend valve assembly is operable to provide the intake of the testing device with only the primary fluid media and to provide the intake of the testing device with a blend of the primary fluid media and the secondary fluid media.

Blend valve

An apparatus for maintaining a constant temperature within a vessel immersed in a liquid by surrounding a portion of the vessel, extending above the surface of the liquid, with a wick. The wick conducts liquid up to a predetermined point on the vessel and maintains the liquid at that point, regardless of changes in the level of the liquid due to evaporation. The wick is encased within a layer of heat insulating or heat conducting material to further aid in maintaining a constant temperature within the vessel. A second embodiment, including alternating layers of heat conducting and heat insulating material, is disclosed for increased temperature control. The disclosed apparatus is particularly useful for maintaining a constant temperature within a vessel attached to a scientific instrument, such as a pore volume and surface area analyzer.

Temperature controlling apparatus for use with pore volume and surface

A continuous volume measuring device for measuring the cumulative volume of a flowing fluid. The device includes a pair of coupled expandable chambers, and the fluid flow is directed into a first chamber to expand it while the second chamber is contracting and expelling liquid therefrom, the expansion of the first chamber being measured to determine the volume of fluid being received therein. When a predetermined volume of liquid is received, a valve means diverts the fluid flow to fill the second chamber, the expansion of which is similarly measured, and the first chamber is emptied. In the preferred embodiment, the chambers are precision syringes.
