Abstract: A multimedia safety analysis system used for system safety training and as an information repository is disclosed. The training device may be web based and may be simultaneously accessed from a computer server by numerous users or executed by an individual user. The system allows a user to investigate a system safety process and aides in the establishment of their own system safety program. The flow of a comprehensive system safety process is illustrated. Each data element in the process has numerous associated data items (information) that define how to accomplish the task associated with the Data Element including references, definitions, examples, acronyms, and specifications given to illustrate more fully what is needed to accomplish the task.

Abstract: A programmable thermostat with a heat-cool switch, a temperature value input, and a fan switch with on, auto, and recirculating positions, and a microprocessor that superimposes a fan recirculating mode or cycle on the heat-cool or off modes or cycles by determining when the heat-cool or off cycles have been off for a user selectable time period; 2 hours, for example, and if so initiating a fan cycle for a predetermined time; 12 minutes for example, to provide a more uniform room temperature by mixing hotter and cooler air and cleaner air by running more space air through the heating and cooling system filter assembly.

Abstract: A method for preventing or inhibiting fouling in a gas-phase polyolefin polymerization process. The method includes maintaining the inside surface temperature of the process equipment below the dew point temperature of the gas mixture passing through the equipment.

Abstract: There are disclosed polymerization processes and associated apparatuses. The polymerization processes involve both making a polymeric material in a fluidized bed reactor having a feed distributor and catching a spitwad with a spitwad catcher, and the apparatuses are those corresponding to such processes.

Abstract: A method for detecting nitro-containing compositions (e.g. nitrate/nitrite materials) in water samples and on solid substrates. In a water sample, ultraviolet light is applied to the sample so that dissolved nitro compositions therein will photolytically dissociate into gaseous nitrogen oxides (NO.sub.2(g) and/or NO.sub.(g)). A carrier gas is then introduced into the sample to generate a gaseous stream which includes the carrier gas combined with any gaseous nitrogen oxides. The carrier gas is thereafter directed into a detector. To detect nitro-compositions on solid substrates, ultraviolet light is applied thereto. A detector is then used to detect any gaseous nitrogen oxides which are photolytically generated during ultraviolet illumination. An optional carrier gas may be applied to the substrate during illumination to produce a gaseous stream which includes the carrier gas and any gaseous nitrogen oxides. The gaseous stream is then supplied to the detector.

Abstract: An insert nestingly receivable within a centrifuge cup to support a pair of fluid containing bags therein is formed from a pair of concave shapes having an upper end and a lower end and which are centrally adhered together in back-to-back relationship. The shapes together with an interior surface of the centrifuge cup together form a pair of elliptically shaped chambers for supporting a pair of the bags within the cup. A pair of pins extend through the concave shapes and extend outwardly therefrom. The bags each are provided with a pair of spaced-apart holes to receive the pins, thereby supporting the bags within the elliptically shaped chambers. Preferably a block is fitted between the adhered together surfaces of the shapes at each lateral edge at the lower ends thereof. These blocks preferably extend laterally outwardly beyond the lateral extremities of the shapes, and the edges of the concave shapes and the blocks are rounded to thereby be nestingly receivable in the interior of the cup.

Abstract: A collection and separation funnel for urine, other body fluids, or environmental samples has dual downspouts so that liquid entering the funnel flows in part down a first downspout and in part down a second downspout. A centrifuge tube is releasably connected to each downspout to receive the liquid. This enables detachment of the centrifuge tubes for delivery to different laboratories. A stand releasably receives the lowermost ends of each centrifuge tube so that the device is free standing and need not be held at the time of liquid collection. A lid is provided for the funnel to facilitate its transportation, and individual lids are provided for each centrifuge tube.

Abstract: Apparatus employing vapochromic materials in the form of inorganic double complex salts which change color reversibly when exposed to volatile organic compound (VOC) vapors is adapted for VOC vapor detection, VOC aqueous matrix detection, and selective VOC vapor detection. The basic VOC vapochromic sensor is incorporated in various devices such as a ground probe sensor, a wristband sensor, a periodic sampling monitor, a soil/water penetrometer, an evaporative purge sensor, and various vacuum-based sensors which are particularly adapted for reversible/reusable detection, remote detection, continuous monitoring, or rapid screening of environmental remediation and waste management sites. The vapochromic sensor is used in combination with various fiber optic arrangements to provide a calibrated qualitative and/or quantitative indication of the presence of VOCs.
