Abstract: ABSTRACT OF THE DISCLOSURE        A melting furnace includes a crucible surrounded by a wall to form an annular heating chamber.  A burner provides a long combustion flame which circulates through the annular chamber to heat the exterior of the crucible.  The combustion flame and hot gases in this chamber are exhausted through a stack having a first exhaust port at the top of the stack and a second exhaust port on the side of the stack.  A duct, connected to the stack at the second port, provides a path for ducting the combustion flame and gases into the mouth of the crucible to melt a charge therein.  The first exhaust port is selectively opened and closed, as by a damper, to alter-natively direct the combustion flame and gases either (a) through the first port to the atmosphere, or (b) through the second port, into the duct, and into the mouth of the crucible.  When the first port is open, noxious fumes from the crucible are advantageously drawn through the duct and into the exhaust stack.

Abstract: ABSTRACT OF THE DISCLOSURE            A transition block connector serves as a fastening point for a plurality of terminal screws which extend through holes in the spaced-apart conductors of a flat flexible cable.  To provide fastening points for the spaced-apart screws, and to accommmodate variations in the spacing between them, mating fasteners are moveably mounted in a housing which is formed of electrically insulating material.  The moveable mounting includes a recess in the housing for each fastener which has internal dimensions larger than the external dimensions of the fastener, and a portion of the fastener has a non-circular exterior configuration which cooperates with a portion of the recess having a non-circular configuration to prevent rotation of the fastener within the recess while permitting lateral displacment of the fastener relative to the housing.  The housing is formed in two parts which define an internal shoulder which in turn cooperates with an external shoulder on the fastener to prevent withdrawal of the fastener from the recess when the two parts of the housing are joined together. A conductive support plate coupled to the housing includes an electromechanically coupled threaded fastener which cooperates with a through opening in the housing to permit coupling of a conductor of a flat cable directly to the support sheet for grounding purposes.

Abstract: ABSTRACT OF THE DISCLOSURE     An optical recording system has a system optical apparatus carried by a fine tracking system which moves the optical apparatus for small track seeking movements and for truck following.  The fine tracking system is carried by a linear actuator coarse tracking system which makes large track seeking movements so that the entire area of the optical recording media is available to the system.  Both the coarse tracking system and the fine tracking system are operated by servo control loops.  The fine tracking system responds to tracking status signals with respect to track following and track seeking signals in response to track addressing information.          The coarse tracking system responds to position sensor signals derived from a position sensor which is associated with the fine tracking system and provides signals related to the relative position of the fine tracking system to the coarse tracking system.  The coarse tracking system follows the movements of the fine tracking system using signals from the position sensing system as the only necessary control for the coarse tracking system.
