摘要： A system for dewatering a stream of slurry has a first and a second separator. The first separator removes objects above a first size, to produce a stream of primary treated slurry. The second separator removes objects above a second size from the primary treated stream, the second size being smaller than the first size. Optionally, a third separator removes objects above a yet smaller third size from the stream of secondary treated slurry. The first separator has a plurality of sieve mat supports alternately connected to a main support frame section and a movable support frame section so that the flexible sieve mat can be agitated by the movable support frame section, a collector being provided for collecting the primary treated slurry passing through the flexible sieve mat. In an optional step, water contained in the separated solids is removed.

摘要： A system and method for dewatering a continuous stream of slurry at high flow rates demonstrates enhanced efficiency, economy and ease of operation. A stream of slurry is subject to continuous or continual measurement of flow rate and pulp density and the measurements are used to control the rate of addition of a flocculating agent to the slurry. The flocculated slurry is delivered to a dewatering unit where it is passed through a diffuser and evenly delivered to a tracking screen for filtering solids from a liquid filtrate. The pulp density of the filtrate may also be measured and used to control addition of a flocculating agent. The tracking screen is adjusted to achieve an angle of repose suited to the particular composition of the filter cake. The diffuser has a base having a horizontal section aspect ratio of from about 1:1 to about 4:1 and continuously changing vertically into an upper portion having a horizontal section with an aspect ratio of from about 40:1 to about 100:1. The ratio of the horizontal sectional areas at the upper portion with respect to the base is from about 1:1 to about 3:1. The dewatering unit of the invention may be adjustably mounted on a transport means for deployment of the high speed dewatering system and method at any convenient location.

摘要： A roofing panel with elastomeric coating incorporates a substantially rigid core with opposed first and second faces. In a preferred embodiment, the core is formed at least partially of portland cement and has a fibrous glass material attached to its first face and a woven polyester material attached to its second face. An elastomeric coating is also provided which is attached to the woven polyester material opposite the core, thereby forming a liquid impermeable layer at an exterior face of the panel. A method for incorporating the roofing panel of the present invention into a roofing system is also provided.

摘要： There is provided a device and manner for bulge forming and bending a tube or hollow extrusion, such as a pipe or conduit. The one portion of the length of the tube is bulge-formed to define a radially expanded, contoured section of the tube, while another portion of the tube length is bent to define an angle or curve in the tube. The device employs a radially expandable mandrel which serves both as the expandable member for bulge-forming the tube, as well as a bending mandrel to stabilize the tube against wrinkling or collapse during bending.
