Abstract: A system is presented for remotely measuring a concentration of a target material (e.g., radioactive gas, suspended aerosols or non-radioactive gaseous chemistries). The system includes a data processing system and a monitoring device. The device includes a detector having a chamber, collector in the chamber and a sensor. The target material enters the chamber. The collector collects ions generated by decay of the material. In one embodiment, the sensor measures changes in an electrostatic potential of the collector in response to the ions. In another embodiment, the sensor includes a scintillation counter that measures alpha or beta particles and provides an energy spectrum. In another embodiment, the sensor includes a material whose optical properties vary according to fields formed within the sensor. The device includes a transmitter for transmitting the potential, the spectrum or the field strength to the processing system for determining the concentration of the target material.

Abstract: A zinc metallized film capacitor includes a dielectric fluid comprising epoxidized soybean oil having at least one epoxy group per molecule, preferably four epoxy groups per molecule. Utilizing epoxidized soybean oil with zinc metallization results in a substantial performance improvement under high temperature and high voltage conditions, providing a zinc metallized film capacitor of reduced size and cost. In addition, the epoxidized soybean oil is relatively non-toxic, reducing environmental concerns.

Abstract: A metallized film capacitor includes an aromatic ester dielectric fluid including 2.0-5.0% by weight of an epoxide in an aromatic ester such as dioctyl phthalate. Utilizing such a particular amount of epoxide results in a substantial performance improvement under high temperature and voltage conditions, providing a metallized film capacitor of reduced size and cost.

Abstract: Organic photoconductive elements which are stable and sensitive over a broad range of the spectrum, including the near infrared band, having a charge generating layer and a charge transport layer carried on an electroconductive support are disclosed. The invention involves the use of a first layer between the support and the charge generating layer which is capable of functioning as (i) an adhesive bonding layer on the electroconductive support to provide a receptive and retentive base layer for the charge generating layer and (ii) as a barrier layer to prevent substantially any leakage of charge from the surface of the photoconductor, characterized by the first layer comprising at least one polycarbonate having a weight average molecular weight ranging from about 25,000 to about 45,000, in combination with a charge generating layer that comprises at least one organic pigment which is sensitive to near infrared radiation.
