Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and method for determining the three-dimensional surface profile of the charge or burden in a furnace.  A pair of infra-red radiation measuring instruments receives infra-red rays from temperature-characterized points on the surface and generates temperature-position signals for the points.  Signals generated by a first instrument are paired with the signals generated by the second instrument that correspond to identical temperature-characterized points.          The position in space of each temperature-characterized point is determined from the known relative positions of the instruments and the two position components of the paired signals.

Abstract: IMPROVED PLUG VALVE     Abstract of the Disclosure A valve, of the type employing a plug rotatable through substantially 90° between open and closed valve posi-tions, employs a plug which has an elongated configuration along its axis of rotation with the opposing ends of said elongated plug each exhibiting a spherical, ellipsoidal, or other curved configuration that merges smoothly into the elongated sides of the plug.  The plug is provided with a passageway which is elongated in the direction of elongation of the plug and which extends through the plug in a direction transverse to the axis of rotation of the plug.  The plug surface is sealed relative to the valve housing by at least one continuous seat of elongated closed loop configuration which engages the surface of the plug along a continuous noncircular line or band having a direction of elongation extending generally in the same direction as the central axis of the plug.  The valving and sealing functions of the improved valve are similar to those of a conventional spherical ball valve, but achieve a given port area by use of a plug having a smaller cross section relative to the turning axis, than would be required of a ball exhibiting that port area.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a novel method of manufac-turing a sacrificial anode rod assembly for cathodically protecting the internal surfaces of ferrous metal water-containing vessels, such as water heater tanks, which method provides an elongated anode rod member of a galvanically active metal and an externally threaded cap member wherein the anode rod member and cap member are connected in a tightly locked, leakproof engagement which not only results in superior mechanical and electrical properties of the anode assembly but also aids substantially in prolonging the effective life of the anode rod assembly.  In the method of forming the assembly, the cap member which has an internal recess is positioned onto the extremity of the anode rod and axially aligned therewith.  Through the application of a force applied to the cap member, the metal in the extremity of the anode rod is subjected to a metallurgical upsetting operation while not affecting or damaging the integrity of the external surfaces of the cap member or its external threads.  The instant method causes the metal of the extremity of the anode rod member to conform to the shape of the internal recess or bore of the cap member (which recess has at least one enlarged portion remote from its opening).  For further increasing the effective life of the anode rod assembly, the method also advantageously provides for forming a bulged or enlarged portion of anode metal at the base of the cap member.

Abstract: HOLDING ARM     Abstract An accumulating mechanism is provided for use in conjunction with a shear mechanism used in forestry applications.  A tree harvesting apparatus employs a shear mechanism to cut the trees, a grapple mechanism to hold the trees while they are being cut, and an accumulator mechanism to accumulate several trees before depositing a load thereof.  The accumulator mechanism of the present invention comprises an elongated base portion having a forward edge thereof aligned with a rear edge of the shear blade as well as the rear edge of the grapple mechanism.  Pivotally mounted on the base portion of the accumulator mechanism is a holding arm which is pivoted forwardly to grasp cut trees and hold them in place as the harvesting machine moves from place to place to cut subsequent trees. The holding arm has a curved inner surface and is engageable with a forward projection of the accumu-lator base to retain trees in the space provided therebetween.          The outer surface of the holding arm is concentric with the pivot axis of the accumulator mechanism to readily enable the holding arm to be extracted from between a newly cut tree and the group of trees already accumulated.  The arm is then closed to encompass both the newly cut tree and the trees already accumu-lated.  A hydraulic cylinder is disposed between the base of the accumulator mechanism and the holding arm to extend and retract the holding arm during the accumulation process.

Abstract: ABSTRACT OF THE DISCLOSURE An interactive video game, wherein player symbols representing "team members" are shown on the screen of a television receiver or cathode ray tube monitor and are caused to move through a series of preprogrammed moves.          Each of the individual "team-member" symbols shown on the screen first appear in a preprogrammed formation or grouping of the various player symbols.  A keyboard entry system displaying directional arrows is then used by the human participant to program a plurality of directional moves of a particular player symbol.  Having completed the preprogram-ming of a particular player symbol, the human participant may next preprogram a similar sequence of keystroke entries for each of the remaining programmable player symbols.  When both participants have programmed all of their "team members" a processor is instructed to cause the desired symbol move-ments to be executed on the television screen.  The game further includes the complementary use of joysticks colocated with each of the direction command entry keyboards to allow shifting the location of one's entire "team" on-screen or to allow movement to speed up or slow down players.  This latter feature allows the participant to superimpose manual positioning control on those resulting from the participant programmed processor machine-commands.  The same directional-command keyboards also initiate the motion of certain symbols during actual game play.
