Abstract: A platesetting system and apparatus for providing computer-to-plate electrophotographic printing to a conductive plate. The apparatus may include an electrophotographic printer adapted to include an electrically isolated media path for receiving a conductive plate. A conductive plate may include anodized and grained aluminum (AL) that does not include a light sensitive emulsion layer in a finished product. The plate may be adapted to include rounded corners. The plate may be adapted to include a protective leading edge. The plate may be fused using the absorbed light of a radiant heat source.

Abstract: In the apparatus of the present invention, air flow control inserts are disposed within the formed tube air outlet manifolds of a heat exchanger of the counterflow type wherein the manifolds have openings communicating with air passages of the heat exchanger core. Each insert is generally tubular in shape, having an intermediate cylindrical tube portion, and larger diameter, end portions, which are substantially equal to the diameter of an outlet manifold. Each intermediate insert portion is initially provided with a plurality of peripheral, longitudinally equally spaced slots, equal in number to the number of openings in a manifold, and of such circumferential lengths as to subtend angles substantially equal to the angles subtended by the manifold openings. Tube material adjacent the slots is then urged inwardly of the tube to form apertures, and adjacent louvers.

Abstract: A heat exchanger of the formed plate type with a stack of relatively thin material, spaced heat transfer plates. The plates of the heat exchanger are arranged to define sets of multiple counterflow fluid passages for two separate fluid media alternating with each other. Passages of one set communicate with opposed manifold ports on opposite sides of the core matrix. Passages of the other set pass through the stack past the manifolds in counterflow arrangement and connect with inlet and outlet portions of an enclosing housing.An assembly of two plates oppositely disposed establishes integral manifolds for one of the fluid media through the ports and the fluid passage defined between the plates. A third plate joined thereto further defines a passage for the second fluid media to flow between the inlet and outlet portions of the housing. The various fluid passages may be provided with flow resistance elements, such as fins, to improve the efficiency of heat transfer between adjacent counterflow fluids.

Abstract: A formed plate heat exchanger of the air and hot gas counterflow type for gas turbines with provision for thermal response zones of different heat transfer capability in the hot gas passages of the core, each succeeding zone in the gas flow direction having greater heat transfer capability than a preceding zone to reduce temperature gradients and core thermal fatigue, with elimination of core cracking and splitting.

Abstract: Heat exchanger apparatus for a gas turbine which is provided with a heat exchanger of the formed plate counterflow type including a core having a gas turbine exhaust gas inlet surface with integral air outlet manifolds, and an inlet gas temperature controller which controls the temperature of the gas impinging on the manifolds and core surface. The temperature controller consists of a housing defining a gas flow path to the heat exchanger core surface, fluid passages within the housing which direct the gas at substantially full gas temperature onto the manifolds, and heat absorber structure within the housing which absorbs heat from the gas to reduce the temperature to less than full gas temperature during transient conditions, such as turbine start-up, and directs the gas onto the core surface.
