    摘要： The concept of this invention is to provide a thermal geometry which produces web growth at a constant width by balancing the heat loss pattern from the growing dendrites in such a manner that the outer requirements for stable web growth are simultaneously met. This is accomplished by configuring the geometry of the growth system such that the heat loss pattern from the growing web, the heat loss pattern from the growing dendrites, and the temperature profile in the melt can each be controlled independently and simultaneously optimized.

    摘要： A valve includes a housing with at least one inlet and at least one outlet with a valve member provided within the housing. The valve member is selectively positioned to control communication between the at least one inlet and the at least one outlet with the valve housing having a teeth ring with a plurality of teeth directed generally radially inwardly and generally toward the interior of the valve housing. In a preferred embodiment, an annular sealing member is provided between the teeth ring and the valve member with a first shoulder limiting movement of the teeth ring toward the valve member. An annular ring is provided between the teeth ring and the first shoulder and a second shoulder is provided between the first shoulder and the valve member. A third shoulder is provided between the second shoulder and the valve member with the third shoulder having a diameter corresponding to the outside diameter of a pipe to be received within the teeth ring.

    摘要： A nitrogen doped single crystal silicon carbide boule is grown by the physical vapor transport process by introducing nitrogen gas into the growth furnace. During the growth process the pressure within the furnace is maintained at a constant value, P.sub.o, where P.sub.o .ltoreq.100 Torr. This is accomplished by measuring the pressure within the furnace and providing the pressure measurement to a process controller which regulates the nitrogen introduction as nitrogen gas is incorporated into the crystal structure. The partial pressure of the nitrogen may be selected to be at a value between 1 and P.sub.o. If the desired partial pressure is less than P.sub.o, an inert gas is added to make up the difference.

    摘要： An arrangement for testing a fire suppression sprinkler system includes a supply conduit for supplying a fire suppression fluid to a plurality of sprinklers. A sensor senses a flow of fire suppression fluid through the supply conduit. A drain conduit drains fire suppression fluid when the fire suppression system is tested. A drain valve controls the flow of the fire suppression fluid so that when the fire suppression system is tested the fire suppression fluid is controlled to enter the drain conduit. A fire suppression fluid collection tank collects the fire suppression fluid which has entered the drain conduit for reintroducing the collected fire suppression fluid to the supply conduit. A circulation valve controls the flow of the fire suppression fluid so that when the fire suppression system is tested the fire suppression fluid enters the fire suppression fluid collection tank.
