Abstract: A method of manufacturing a tube sheet by forming a plurality of separate thin tube sheet segments; forming multiple holes in each sheet in a predetermined pattern, each hole for accommodating a tube sheet filter tube; aligning all of the plurality of tube sheet segments so that the hole pattern of each sheet aligns with the hole pattern in all other sheets of the plurality of tube sheet segments; and securing all of the tube sheet segments together to form a unitary tube sheet. A tube sheet construction that includes a plurality of separate thin tube sheet segments, multiple holes being provided in each sheet in a predetermined pattern, each hole for accommodating a tube sheet filter tube, all of the tube sheet segments being aligning so that the hole pattern of each sheet aligns, and fasteners for securing all of the tube sheet segments together. A media layer is provided between adjacent sheet segments.

Abstract: A screening apparatus that includes a strainer element used for the purpose of retaining particulate while permitting the passage of a liquid through the strainer element, a support structure for the strainer element to enable rotation of the strainer element between opposed 180 degree positions, and a control member coupled with the strainer element for controlling the rotation of the strainer element. The strainer element, in both opposed positions thereof impedes any particulate while permitting the passage of a liquid. The control member is constructed so that, in a first state thereof, the rotation of the strainer element is periodically controlled to rotate the strainer element between said opposed 180 degree positions, and in a second state thereof, inhibits rotation of the strainer element.

Abstract: A heat exchanger that is constructed with a heat exchanger shell having inlet and outlet plenums and fluid inlet and outlet ports, and a tube sheet construction disposed in the heat exchanger shell. The tube sheet construction includes at least two separate tube sheets and a plurality of tubes that extend between the separate tube sheets. Each tube sheet includes at least two planar tube sheet segments and an interstitial layer disposed between the at least two tube sheet segments, and at least one sensor element supported by each of the interstitial layers. A control monitor controls flow through the shell by a feedback control from the sensor to an inlet control valve and/or a stimulus device excites the media layer.
