    Abstract: Multiple spatially diverse and compact weight sensors are statistically combined to reduce or eliminate errors caused by snow bridging. Data transmission using satellite communication minimizes the power consumption of the sensor station further allowing the entire system to be relatively compact and easily transported. The weight sensors may be combined with other standard sensors for measurement of air temperature and snow height, the latter measurement, for example, using ultrasound ranging or the like.

    Abstract: A prefabricated sprue assembly provides attachment to independently-produced investment casting molds to substantially reduce the need for pattern material. Installable connections between the prefabricated sprue assembly and the investment mold allow substantial reduction of scrap loss caused by errors in production of individual investment molds by culling defective molds before installation to the sprue assembly.

    Abstract: An investment casting method involves producing a casting shell by applying a hardenable refractory material to a sacrificial pattern. The casting shell having a plurality of phosphate bonds in the hardenable refractory material, which provide increased structural integrity during casting and improved frangibility during shell removal. The casting shell may also have a plurality of gaseous pockets suspended in the refractory material, which do not degrade the structural integrity during casting and provide improved frangibility during shell removal.

    Abstract: The present invention is a process and apparatus for forming various bio-products from cellulosic plant material. The plant material is subjected to a pulping step in which lignin is extracted from the material by an aqueous lignin solvent to form a lignin-solvent mixture and purified cellulose. The lignin-solvent mixture can be separated from the water to form a high energy density fuel that can be used independently or combined with biodiesel. The purified cellulose can be used in conventional processes, e.g., paper making, or can be converted to fermentable sugars with a cellulase enzyme to produce other bio-products depending on the operating conditions of the fermenter. The bio-products produced by the fermenter can include the solvent that may be recycled for use in extracting the lignin.
