Abstract: ABSTRACT         A self-cleaning heat exchanger in combination with a home furnace system which draws combustion air from outside the home is disclosed.  Gases of combustion are drawn up through a plurality of vertical tubes and out a chimney by a fan mounted in the chimney.  The lower portions of the tubes are cooled by inside air drawn over them by the return air blower of the furnace, the upper portions of the tubes are cooled by cold outside air drawn across them by the furnace burner unit. Moisture which condenses in the upper portions of the tubes is drawn down through them by gravity.  The higher temperature in the lower part of the tubes causes this condensate to revaporize and rise to the upper portion of the tubes, where the process repeats itself.  As more water vapor enters the tubes in the flue gas, distilled condensate eventually drops out of the tubes and runs into a drain at the lower end of the heat exchanger.  The moisture from condensation of the combustion gases scrubs pollutants from the flue gases passing through the tubes, and is slightly acidic, providing a clean-ing function for the interior of the heat exchanger tubes. The heat exchanger is also suitable for use in commercial furnace systems and combustion-type power plants which utilize outside air for combustion.

Abstract: GRAPHICS GENERATOR            Abstract of the Disclosure A graphics generator responds to signals defining a pattern to be displayed.  The pattern comprises a plurality of pattern segments each of which may be a vector, conic or alpha numeric character.  The graphics generator produces digital signals which are capable of driving a display through an A/D converter to produce a visual representation of the desired pattern segment.  The pattern segment is broken up into a plurality of strokes of constant length regardless of orientation.  Chaining the strokes on the display thus produces the desired pattern.  An input signal defining a vector defines both the length and the orientation of the vector and these quantities are stored in length and orientation registers, respectively.  The orientation signal is employed as an address into a sine/cos memory to derive stroke com-ponents in an orthogonal coordinate system which are then added to a beginning position of the stroke to produce the stroke end point.  At the same time, a counter containing a quantity representative of the length of the desired vector is decremented.  Repeating this process produces a series of digital signals representing strokes of constant length which can drive a display to produce the desired vector.  Conics are produced in much the same manner except that the orientation register is incremented by a predetermined quantity for each cycle (or once in a determined number of cycles) thereby producing strokes whose orientation changes at a constant rate.          Characters can be written at any desired orientation, by accessing a character definition memory storing signals representative of a plurality of pattern segments defining the particular character.

Abstract: ABSTRACT       Apparatus for deploying a plurality of twisted pairs of wires and separating the two wires of each pair, comprises a templet having recesses extending there across in one direction.  Each recess has one portion which is dimensioned to receive a single twisted pair of wires and the one portion of each recess merges with another portion comprising two separate juxtaposed grooves, each of which is dimensioned to receive one wire only of a twisted pair.  The twisted pairs are pressed onto the recesses by a roller which moves across the templet.  A wire controller bar is mounted adjacent to, and in advance of, the roller and the twisted pairs extend from beneath the roller over the controller bar.  When the roller approaches the portions of each recess which receive only a single wire, the spacing between the roller and the controller bar changes so that they are separated by a distance substantially equal to the diameter of a single wire.  The reduced spacing between the roller and the controller bar causes the individual twisted pairs to become untwisted so that the two wires of each twisted pair are pressed into the two grooves.

Abstract: ABSTRACT OF THE DISCLOSURE             Apparatus and a method of manufacturing a formed coil having multiple single row coil cores of varying lengths.  Sheets of fins are cut from plate fin stock such that the fins within each sheet are connected to each other by rupturable tabular portions.  The sheets of fins are then arranged in registration such that openings within the fins for the receipt of tubes are aligned and tubular members or hairpins may be inserted within the fins to form part of the fluid flow circuit of the coil.  Since the hairpins for adjacent coil rows are of different lengths, when the multiple row coil core is bent each coil row is formed about a separate radius curvature so that the formed coil will be in the desired configuration.  Prior to bending, the hairpins are expanded to form a heat transfer bond with the fins, the expansion process acting to rupture the tabular portions connecting the fins such that the fins on the hairpins become separately spaced along each hairpin.  Thereafter the coil core is bent to the desired formed coil configuration wherein the fins are spaced distinctly along each coil row notwithstanding that the fins were originally from the same sheet and connected to each other by the tabular portions.
