摘要： A method of forming a sheet wafer 1) passes at least two filaments through a molten material to produce a partially formed sheet wafer, 2) directs a cooling fluid at a flow rate toward the partially formed sheet wafer to convectively cool a given portion of the partially formed sheet wafer, and 3) monitors the thickness of the given portion of the partially formed sheet wafer. To ensure appropriate thicknesses of the wafer, the method controls the flow rate of the cooling fluid as a function of the thickness of the given portion of the partially formed sheet wafer.

摘要： A vehicle airstream deflector is provided. The deflector provides an air curtain to divert oncoming air flow past the passenger cabin of a vehicle, thereby reducing drag. Furthermore, air flow from the rear of the vehicle is induced to move forward, providing additional vehicle momentum in the direction of travel.

摘要： A method for collecting condensate includes filling a cylindrical container with a column of coarse sand and mounting the container coaxially to the output end of a furnace conduit through which heated gases containing sublimate will pass. A layer of gas permeable material holds sand in position and an aperture in its center assists in directing gases generally to the center of the sand column. The sand column is spaced away from the furnace a distance such that the temperature differential will cause condensation of the heated gases on the surfaces of the sand particles.

摘要： A broom assembly is provided. The broom assembly includes a broom head which comprises an elongated back plate and a plurality of bristles extending from the back plate. The broom assembly also includes an elongated mounting plate which is attached to the back plate and extends over a longitudinal end of the back plate. A handle receiving bracket is attached to the mounting plate, projecting the same direction from the mounting plate as the broom head. The handle receiving bracket comprises at least two receiving cavities for attaching a handle. The broom assembly further comprises an elongated handle for insertion in the handle receiving bracket.

摘要： A sand collection system includes a column of coarse sand within a cylindrical container coaxially mounted to the output end of a furnace conduit through which heated gases containing sublimate will pass. A layer of gas permeable material holds sand in position and an aperture in its center assists in directing gases generally to the center of the sand column. The sand column is spaced away from the furnace a distance such that the temperature differential will cause condensation of the heated gases on the surfaces of the sand particles.

摘要： A furnace arrangement utilizes a single vertically disposed shaft furnace incorporating the features of pellet drying and hardening, oxidizing heat-up, reducing roast and gas separation. The upper portion of the furnace dries and hardens "green" pellets while at the same time subjecting them to an oxidizing atmosphere and temperature increase. A stack of the pellets slowly moves downwardly through a transistion zone to a reducing atmosphere in a lower portion of the furnace. A heated reducing gas circulates through this lower portion and out of the furnace through a recovery system of the furnace arrangement. After the sublimate carried by the reducing gas is removed, the reducing gas is supplemented and returned to the lower portion of the furnace to again produce a reducing atmosphere. A smaller branch of cooled reducing gas enters the lower portion of the furnace adjacent the bottom to cool the pellet residue immediately prior to removal from the furnace.
