The present invention is an improved method and related apparatus for quantitatively analyzing machine working fluids and other aqueous compositions such as wastewater which contain various mixtures of cationic, neutral, and/or anionic surfactants, soluble soaps, and the like. The method utilizes a single-phase, non-aqueous, reactive titration composition containing water insoluble bismuth nitrate dissolved in glycerol for the titration reactant. The chemical reaction of the bismuth ion and glycerol with the surfactant in the test solutions results in formation of micelles, changes in micelle size, and the formation of insoluble bismuth soaps. These soaps are quantified by physical and chemical changes in the aqueous test solution. Both classical potentiometric analysis and turbidity measurements have been used as sensing techniques to determine the quantity of surfactant present in test solutions. This method is amenable to the analysis of various types of new, in-use, dirty or decomposed surfactants and detergents.

The present invention is a thermometer used for measuring furnace temperaes in the range of about 1800. degree. to 2700. degree. C. The thermometer comprises a broadband multicolor thermal radiation sensor positioned to be in optical alignment with the end of a blackbody sight tube extending into the furnace. A valve-shutter arrangement is positioned between the radiation sensor and the sight tube and a chamber for containing a charge of high pressure gas is positioned between the valve-shutter arrangement and the radiation sensor. A momentary opening of the valve shutter arrangement allows a pulse of the high gas to purge the sight tube of air-borne thermal radiation contaminants which permits the radiation sensor to accurately measure the thermal radiation emanating from the end of the sight tube.

A method and apparatus for continuously drying and regenerating ceramic beads for use in process gas moisture drying operations such as glove boxes. A microwave energy source is coupled to a process chamber to internally heat the ceramic beads and vaporize moisture contained therein. In a preferred embodiment, the moisture laden ceramic beads are conveyed toward the microwave source by a screw mechanism. The regenerated beads flow down outside of the screw mechanism and are available to absorb additional moisture.

Apparatus for limiting access to items only during pre-determined times, a lockable container system includes a lockable container assembly and a remote control unit. The remote control unit includes an input keypad, a display, a processor, and a transmitter. The lockable container assembly includes a receiver, a locking mechanism, and an indicator. The pre-determined time that the lockable container assembly is able to be unlocked is entered on the keypad. When the predetermined time arrives, the remote includes an operator that, when actuated, sends an unlock signal to the lockable container assembly. At other times, the lockable container assembly remains locked, thereby limiting access to its contents. In one embodiment, the container includes perforations that ensure the inside environment matches the environment outside the container.

A personal safety system is designed for a user of a vehicle. The system includes body-protective gear adapted for wear by the user of the vehicle. A sensor determines a positive or negative functional state of the body-protective gear. In the positive functional state, the body-protective gear is presumed to be properly applied to a body part of the user; and in the negative functional state, the body-protective gear is presumed to be improperly applied to the body part of the user. A transceiver is operatively connected to the sensor, and communicates the functional state of the body-protective gear to the vehicle. When the body-protective gear is in the negative functional state, operation of the vehicle is restricted.
