Abstract: A method of making LSO scintillators with high light yield and short decay times is disclosed. In one arrangement, the method includes codoping LSO with cerium and another dopant from the IIA or IIB group of the periodic table of elements. The doping levels are chosen to tune the decay time of scintillation pulse within a broader range (between about ˜30 ns up to about ˜50 ns) than reported in the literature, with improved light yield and uniformity. In another arrangement, relative concentrations of dopants are chosen to achieve the desired light yield and decay time while ensuring crystal growth stability.

Abstract: LSO scintillation crystals with improved scintillation and optical properties are achieved by controlled co-doping a LSO crystal melt with amounts of cerium and an additional codopant such as calcium or other divalent cations. Crystal growth atmosphere is optimized by controlling the amount of oxygen in the atmosphere. Zinc is added as an additional material to restabilize crystal growth where calcium co-dopant is added. The decay time of the scintillation crystal can be controlled by controlling the concentration of co-dopant added.

Abstract: A phantom for use in quality control measurement of a fully integrated magnetic resonance/PET scanner is disclosed. The phantom features radiation activity distributed throughout an electrically conductive binder. Suitably, the binder is elastomeric and includes carbon fibers distributed throughout it to set the conductivity of the phantom to a desired level. The phantom is applicable to various multimodality integrated medical imaging systems such as MR/SPECT and MR/CT in addition to MR/PET.

Abstract: A phantom for use in generating a normalization data set to be used in PET scanning (particularly integrated MR/PET scanning) is disclosed. The phantom features radiation activity distributed throughout a foam material. The foam—e.g., a polyurethane foam—may be produced by reacting two liquids, one of which is emulsified with water in which Ge68 has been dissolved. The foam produced thereby exhibits uniform distribution of radioactivity and a long mean free path for 511 keV gamma particles—two attributes that are important attributes of a PET phantom.

Abstract: A method and apparatus for determining a concentration of water in an oil mixture using both the Karl Fischer test method and spectrochemical analysis. The invention allows for chemical species that masquerade as water in an oil mixture to be identified and accounted for in determining a more accurate water concentration measurement than by using the Karl Fischer test method alone.

Abstract: A method is disclosed for acquisition and analysis of condition monitoring data. Alarm and alert limits are set to proper levels and information regarding the frequency and cause for alerts is collected. Analysis of the information may then be performed to provide a user with easily understandable representations of the system errors and suggested actions.

Abstract: Solid particles combined with a water contaminated oil sample are counted by an optical particle counter. The contaminated oil sample is mixed at a substantially 1:1 ratio with a water masking solvent comprising about one part isopropanol and about three parts toluene. The oil and solvent mixture is passed through a transparent viewing volume between a light source and a light detector for detection and counting of oil suspended solid particles.

Abstract: A method and apparatus for automatically detecting a lubricant type and the relative quantity of water present in a test sample of lubricating oil includes the use of an open grid capacitive sensor element that incorporates the lubricating oil as a dielectric medium. The sensor element grid is energized by a frequency variable oscillator that automatically responds to changes in the oil dielectric constant with corresponding frequency changes. As a reference, a sample of new or uncontaminated test oil is confined in wet surface contact with the energized, open grid sensor element. Oscillator frequency changes are measured and recorded, either continuously or at frequent intervals, over a standardized elapsed time interval to generate a reference characterization of the frequency-time relationship distinctive of the particular oil. The same is repeated for a sample of contaminated oil and a corresponding frequency-time relationship generated.

Abstract: The chopping device includes a rotary cutting tool having peripheral cutting teeth with gaps between the teeth, which cooperates with an opposing knife element to chop up a workpiece and a clearing device which enters into the gaps between the teeth during operation to remove chopped up pieces of the workpiece from the gaps. To provide an economical and strong chopping device the opposing knife element and the clearing device are provided with a single rotatably driven counter tool. The single counter tool has a rotation axis parallel to the rotation axis of the cutting tool and displaced radially from it, a rotation direction opposite to that of the cutting tool and a rotation speed which is maintained in a fixed relationship to that of the cutting tool.

Abstract: This invention relates to a method of controlling the viscosity of siloxane oils in the presence of lead by adding a small amount of a dione such as p-benzoquinone or 2,3-butanedione.
