Abstract: ABSTRACT OF THE DISCLOSURE   End of character flag bits are stored in each character matrix, which matrix defines a character shape as a pattern of binary ones and zeros, and which is stored in a character generator memory, to provide a means and method of proportionally spaced character printing. The character matrix starting addresses of a series of characters to be printed are stored in an output line buffer memory.  Each time the memory is inter-rogated by an output line buffer address counter, a new starting address is loaded into a character generator address counter from the output line buffer memory.  As the counter increments, portions of the selected character matrix within the character generator are transmitted along with at least one end of character flag bit which bit identifies that portion as either NOT end of character or end of character.  When the end of character is detected it is transmitted to the character generator address counter and to the output line buffer address counter.  In response to end of character, a new starting address is loaded into the character generator address counter stopping transmission of the previously selected character matrix.  The end of character signal to the output line buffer address counter increments the counter to select a new starting address in the output line buffer memory for loading in the character generator address counter upon receipt of the next end of character signal.    Error correction coding capability is added to the end of character flag bit by providing a 3 bit end of character pattern, encoded to provide single bit error correction in the end of character flag.  In addition, a parity bit is added to each transmitted portion of the character matrix.  If checking of the parity of the transmitted portion indicates no error but an invalid end of character bit pattern is detected, a stop print interrupt signal is generated.

Abstract: AIR-COOLED HEAT EXCHANGER                    ABSTRACT OF THE DISCLOSURE      This disclosure relates to an aircooled heat exchanger including first and second sets of tubes that carry a fluid to be cooled.  One end of each tube is connected to an inlet header and the other end is connected to an outlet header.          Each tube includes first and second longitudinal portions which are joined or connected  by an intermediate bent portion.  The tubes are arranged in the flow path of a cooling air flow.  The first portions of the first set of tubes are located upstream, with respect to the direction of air flow, relative to the second portions of the first set and relative to the first portions of the second set, and the second portions of the second set are located upstream relative to the first portions of the second set and to the second portions of the first set.  This offset relation of portions of the tubes substantially equalizes the heat exchange with the air.

Abstract: ABSTRACT OF THE DISCLOSURE           This specification discloses a means for providing a barrier against the passage of fire through that portion of a wall-aperture surrounding an electrical conduit, pipe, or the like.  This is accomplished by placing a sleeve around that portion of the conduit passing through the wall, which sleeve is the central portion of an envelope which is anchored periph-erally to the wall or to a more or less rigid material blocking the aperture through the wall and which sleeve connects to end portions of the envelope, each of which end portions extends to connect with the conduit on an opposite side of the wall.          The annular region between the conduit and the surrounding envelope is filled with an intumescent gel.  The boot is flexible and capable of some movement to compensate for thermal expansion, vibration or other forces during the life of the installation.  In the event of heat and fire, the gel within the envelope intumesces, providing protection against passage of flames and gas through the annular region surrounding the conduit, which annular region is now occupied by a fire resistant mass formed by the solidification of the gel.  The intumescible gel comprises sodium silicate solution, a filler, and a hardener.
