Abstract: A method is provided for utilizing a call block analysis tool of a computer system to determine the number of normal calls blocked on a telecommunication trunk group during a call blast event. After a call blast event has been determined to have occurred during a trunk group's calling hour, the method uses current and history trunk group traffic statistics to determine the number of “normal” calls that were blocked during a calling hour. This method uses historical average holding time, current offered load, current blocking proportions as well as current and historical peakedness to numerically solute for the number of “normal” calls blocked.

Abstract: The present invention relates to a new family of sterol sensing domain proteins which modulate the release of Hedgehog proteins and lipid modified hydrophobic proteins from cells. Such proteins e.g. are involved in developmental processes, differentiation, regeneration and cell homeostasis, making them particularly suitable tools for diagnosis and therapy.

Abstract: The invention is directed to a coating composition for application to a flushable cellulosic based waterleaf sheet to impart transitory water repellency to at least one surface of the sheet. The composition comprises between 20% by weight to about 70% by weight of relatively large particle size delaminated clay in combination with a polyethylene based polymer that has been produced by the drying of a colloidal polyethylene in water composition with the said clay.

Abstract: A recirculating oven in which air and oxidized gases from a burner tube are directed to evaporation zone outlets at the bottom of the oven and curing zone outlets at the top and fed into a pair of wire work chambers, the gas streams mixing between the zones and return with volatile substances through a return duct to a burner mounted in the upper portion of the burner tube. The burner tube is mounted within a burner tube housing partitioned so that the volatile fumes returning to the burner are maintained separately from the oxidized gases and air exiting from the burner tube. The burner is electrically energized and has a cylindrical housing supporting a number of radial vanes supported between spaced baffle plates, the vanes imparting a vortex pattern to the gases entering holes in the housing periphery. A support plate on the top of the housing carries two high temperature ceramic igniter heater elements surrounded by a multiplicity of resistance type electrical heating elements.

Abstract: A recirculating oven having dual air plenum chambers each controlled by an individual blower receiving air and oxidized gases from a burner tube intermediate the plenums. The gases leaving the burner tube are drawn by the blowers into the respective plenum and enter a pair of evaporation zone modules at the bottom of the plenums and a curing zone module at the top are fed into a pair of wire work chambers, both air streams mixing between the zones and return with volatile fumes through a return module to a burner mounted in the upper portion of the burner tube which receives the mixture in a swirling fashion from a vortex generator between the tube and burner. The burner tube is mounted within a burner tube housing partitioned so that the volatile fumes returning to the burner are maintained separately from the oxidized gases and air exiting from the burner tube.
