Abstract: A method and apparatus for managing spare partition units in a partitionable computing device is disclosed. The method comprises detecting if a spare partition unit is required for addition or replacement in a local operating system and if a spare partition unit is required for addition, initiating an addition of a spare partition unit. If a spare partition unit is required for replacement, a replacement of a failing partition unit with a spare partition unit is initiated; part of the memory of the failing partition unit is passively migrated into the memory of the spare partition unit's partition; part of the memory of the failing partition unit is also actively migrated into the memory of the spare partition unit's partition; and the partitionable computing device is cleaned up. Partition units are replaced without requiring that computer-executable instructions be recompiled.

Abstract: A tool is provided for supporting the human upper body when having to lean over to work. The tool comprising a platform member for supporting the human upper body in a leaning position thereby reducing back muscle strain and fatigue; a cushioned pad secured to an upper surface of the platform member providing a cushioned interface between the human upper body and the platform; an omni-directional tilt and swivel member secured to a bottom surface of the platform member; an elongated telescopic height adjustment member comprising two or more elongated telescopic sections providing platform height adjustment, said sections being separable from one another so that sections may be removed or added as desired; one or more removable base members, the base member being removable to permit replacing the base member so as to accommodate base member configured for different floor or support conditions.

Abstract: There is disclosed a current tank system comprising a first current tank adapted to produce a first current in a first direction; a second current tank adapted to rotate to produce a second current in a second direction; a sample adapted to be exposed to the first current and the second current.

Abstract: A fluoride monitoring electrode comprises a single crystal of a lanthanum series fluoride doped with alkaline earth ions. The sample pre-treatment solution used in conjunction with the electrode includes a buffer that maintains a pH of 5 to 8 and a complexing agent that complexes iron and aluminum.

Abstract: A radio-pharmaceutical transport system includes a pig and a disposable plastic insert. Together, the pig and the disposable plastic insert provide a mechanism for transporting a syringe containing a dose of a radio-pharmaceutical composition. The pig includes a tungsten cylinder that defines an elongated cavity therein that is substantially coaxial with the tungsten cylinder. The cavity is of sufficient size to receive therein a syringe. The tungsten cylinder has a thickness sufficient to shield users from a PET radio-pharmaceutical without requiring additional shielding. The disposable plastic insert is disposed within the cavity and includes an elongated plastic envelope.

Abstract: A radio-pharmaceutical pig for transporting a syringe containing a radio-pharmaceutical includes a first cylindrical member having a first tungsten body defining a first cavity therein A second cylindrical member has a second tungsten body defining a second cavity therethrough and is capable of engagement with the first cylindrical member so that the first cavity is in substantial alignment with the second cavity. A third cylindrical member includes a third tungsten body defining a third cavity and is capable of engagement with the second cylindrical member so that the third cavity is in substantial alignment with the second cavity. The first cavity, the second cavity and the third cavity are shaped so as to be complimentary in shape of the syringe.

Abstract: A measurement/calibration cell for potentiometrically measuring ion concentration in a fluid interposes a barrier between measuring and reference electrodes and positions the measuring electrode at a sufficiently higher gravimetric potential above the reference electrode that seepage of electrolyte from the latter to the former is effectively precluded. A controller associated with the cell displays instructions and other desired information on a scrolling display such that a substantial amount of information can be presented in a relatively small display window.

Abstract: The combination of reduced flammability and adhesion can be imparted to cured organosiloxane materials when the curable compositions used to prepare these materials contain 1) an adhesion promoting composition comprising up to about 0.1 weight percent, based on the weight of the curable composition, of a chelated organoaluminum compound in combination with an organic epoxide compound and an alkoxysilane or condensation product of the silane, and 2) as a flame-retarding additive, hydrated aluminum oxide and/or magnesium hydroxide, preferably in combination with additional fillers such as quartz.

Abstract: The present invention comprises an electrochemical metering apparatus that provides for convenient storage and presentation of the analytical electrode, simple assembly, and two calibration modes. The apparatus includes an electrode storage and presentation assembly that permits the user to introduce the electrode into a sample solution while simultaneously observing the meter's output, and store the electrode when not in use. All structural components are intended to fit together with interlocking tabs and windows. A serial port fits within the construction of the main housing without the need for bolts, and battery clips that depend directly from the circuit board obviate the need for wiring connections. The present invention also features two calibration modes. A "segment addition" mode permits separation of the voltage/concentration curve into individually plotted regions, the number of which depends on the number of reference solutions used in the calibration procedure.
