Abstract: A system and related method are provided for measuring conductivity/resistivity of water having high purity, including a temperature sensor and a conductivity/resistivity sensor exposed to a water source. The system further includes a computing assembly configured to receive measurement signals from the sensors and to determine change in resistivity over a change in temperature (a collected R/T slope) from the collected temperature measurements and the collected resistivity measurements. The system compares the collected R/T slope to a standardized R/T slope at a temperature value corresponding to a midpoint temperature of the temperature measurements over the prescribed time interval. Based on the comparing, the system provides providing a compensated measurement for resistivity or conductivity of the water source. As a result, the system can calibrate the sensor continually during use, in real time, resulting in highly improved accuracy.

Abstract: A freeze-dried material is stored in a first chamber of a container along with a reconstituting liquid for the freeze-dried material, which is stored in a second chamber of the container. A sealing wall within the container forms a barrier between the first chamber and the second chamber preventing contact between the freeze-dried material and the reconstituting liquid. At least one valve assembly in the sealing wall selectively opens a region of the sealing wall to establish fluid flow communication between the first and second chambers, allowing the freeze dried material to be reconstituted. The reconstituted freeze-dried material can be administered from the same container to a recipient.

Abstract: A vessel receives a liquid material, which is freeze-dried in situ within the vessel. A gas permeable material carried by the vessel provides gas transport for sublimation during drying. After freeze drying, an oxygen-free inert gas is introduced into the vessel through the gas permeable material, to occupy the interior of the vessel with the freeze-dried material. The gas permeable material is covered, to trap the oxygen-free inert gas within the vessel with the freeze-dried material. The freeze-dried material is stored in the entrapped oxygen-free inert gas within the vessel for a storage period. The vessel receives a reconstituting liquid for mixing with the freeze-dried material, and conveys the reconstituted freeze-dried material from the vessel for administration to an individual.

Abstract: A submergible fish cage comprising: a float; a fish cage; at least one (1) anchor weight; and at least one (1) cable, one end of the cable attached to the float element, a middle portion of the cable attached to the fish cage, the bottom end of the cable attached to the anchor element, the cable being shorter than the depth of the water in which the submergible fish cage is placed; the float having a trim tank adapted to be flooded with water, the trim tank adapted to be blown free of water with air, the float element having a minimum of buoyancy sufficient to float itself supporting the fish cage and cable when the trim tank is flooded with water, the float element having a maximum of buoyancy sufficient to float itself supporting the fish cage, anchor weight and cable when the trim tank is charged with air; and the anchor weight having sufficient weight to submerge the float, cage, cable and anchor weight when the trim tank is flooded with water.

Abstract: A protective refractory member for protecting heat-absorptive elements in a high-temperature furnace comprises a refractory shape, an interconnected, reticulated metal mesh embedded within the shape and positioned substantially adjacent an inner surface of the shape and at least one opening extending through a thickness of the shape and through the mesh. A tubular insert is located within the opening and is welded to the spirals which define the mesh. Both the insert and certain of the spirals engage the heat-absorptive element and the insert is welded to the element to retain the member thereto.

Abstract: A ladle preheat station includes a firing wall through which a burner fires into an open end of a ladle juxtapositioned with respect to the wall, an air curtain means positioned about the firing wall so as to direct a curtain of air toward the ladle to eliminate ambient air infiltration between the firing wall and the ladle lip. In a preferred form an insulating refractory is placed along the inner-most edge of the air curtain means to reradiate the radiated heat and minimize slot radiation heat losses.

Abstract: A protective refractory elongated hollow member for protecting pipe and the like in high temperature metallurgical furnaces comprises an arcuately shaped male part and an arcuately shaped female part interconnected at their respective longitudinal edges. The male part includes a clip partially embedded therewithin, which clip includes at least one hook and preferably two extending outward from the longitudinal edge of the part. The female part includes hook-receiving members such as loops partially embedded and extending from its longitudinal edge to receive the hooks. The hooks include locking means or preventive disengaging means for retaining the parts in assembled relationship.
