Abstract: In one version of the invention, an apparatus intended for determining the disintegration time of rapidly disintegrating tablets is designed with a disintegration cell having two liquid inlets and outflow from the top. Visualization of tablet inside the disintegration cell is conducted using a camera aided by a base light source and images captured using a computer or any other recording system. Disintegration medium is introduced into the disintegration cell through both inlets to produce a swirling motion and images of the tablet disintegration process are captured. The captured images are analyzed in real-time or off-line, to determine the tablet disintegration time. A visual non-recording method using projected image may also be used.

Abstract: A cased hole pressure test tool is used to determine the integrity of cement between two points in a borehole in terms of permeability or transmissibility. The test tool drills at least one probe hole through the casing up to the cement. In one embodiment, two probes are set and the dissipation of a pressure pulse through the cement initiated by the first probe is observed by the second probe. In another embodiment, one probe hole is in hydraulic communication with the borehole fluid and a single offset probe is set in another probe hole. Fluid (water) is then added to the borehole to cause a pressure increase in the borehole fluid. Detection of the pressure increase through the cement by the offset probe is indicative of a loss of hydraulic isolation. Packers may be used to isolate the portion of the borehole under test. A mechanism for generating a pressure pulse of known magnitude is also described.

Abstract: A convective accelerometer capable of measuring linear or angular acceleration, velocity, or angle of inclination is provided. The accelerometer comprises sensing elements that are sensitive to convection located inside a sealed housing containing a liquid agent. Applied external acceleration causes forced convection of the liquid agent, which produces variations in an electric current produced by the sensing elements that are proportional to the applied acceleration or angle of inclination. The accelerometer has a small size, extremely wide frequency and dynamic ranges, high sensitivity, simple design and is suitable for mass production. The device has a wide range of application, such as stabilization and control systems, homeland security, and oil exploration.

Abstract: A gas sorption sample chamber contains a plurality of thin-film substrates and fluidly couple said substrates to a Sieverts' device or other gas sorption analyzer. The thin-film substrates are held in proximity to each other in the sample chamber in a columnar arrangement, either in a stacked or slightly spaced configuration, to reduce free-gas volume in the sample chamber, thereby improving sorption test accuracy. The interior geometry of the chamber is configured to provide a minimal clearance between the thin-film substrates and the internal surfaces of the chamber, so that essentially all of the chamber volume is occupied by thin-film sample material and inactive substrate material. To facilitate use in a glove box, the chamber may be configured with a removable sample cartridge in which thin-film substrates are placed so that all substrates may be loaded and unloaded as a group.

The liquid detection chamber includes an abutting surface abutting against a second sealing surface being in contact with a first sealing surface of the movable member and the detection portion installation member. When a distance between the first sealing surface of the movable member to the detection space sealing surface is defined as L1 and a distance between the second sealing surface of the liquid detection chamber to the abutting surface is defined as L2, the relationship L1>L2 is satisfied.
