Abstract: A CIRCUIT FOR IMPLEMENTING A MODIFIED LRU     REPLACEMENT ALGORITHM FOR A CACHE     Abstract of the Disclosure The invention operates with a storage hierarchy buffer such as a cache, with an LRU network which utilizes two array memory chips, array selection and addressing controls, chronology controls, next LRU addressing circuits, and mode controls for controlling the different types of operations needed by the LRU network.   Each time a different block is accessed in the cache, a next use value is generated in a chronology register in the chronology controls, and the new use value is written into the active one of the arrays at a position which corresponds to the position of the block to be replaced in the cache.  An LRU determination is made when a cache miss occurs by making a search of the active array to find the position of the block with the lowest use value, which block position is thus determined to be the LRU.  This LRU block address is then stored in the next LRU addressing circuits for use by the next block replacement in the cache, i.e. next miss.

Abstract: PROCESS AND APPARATUS FOR CLEANING           VERY FINE ORE         Abstract of the Disclosure In an ore cleaning process the underflow from an ore classifying cyclone is delivered to a heavy medium cyclone where the ore is cleaned.  The underflow leaving the classify-ing cyclone is continually measure for specific gravity and flow rate while the specific gravity of heavy medium that can be applied to the underflow is continually measured.  The amount of this heavy medium and the amount of water required to be added to the underflow are continually controlled as functions of the specific gravity and flow rate thus measured, whereby a substantially constant specific gravity and flow rate of the underflow is maintained as it enters the heavy medium cyclone.  Magnetic separating means receive the overflow from the heavy medium cyclone and separate the heavy medium from the ore, while other magnetic separating means receive the underflow from the same cyclone and separate the heavy medium from the rejects.  The heavy medium is used again.

Abstract: ABSTRACT OF THE DISCLOSURE        A concrete form which is particularly suited for casting-in-place concrete structures, such as a building, comprises a plurality of metallic form members that are interconnected so as to define a planar form surface having a plurality of spaced, parallel elongated depressions extend-ing across the entire length of the form.  The resulting con-crete structure is generally planar having a relatively thin planar surface which is reinforced by unitary, spaced, parallel beams formed by said depressions.  The resulting structure is of comparable strength to a thicker slab of concrete, requires less concrete, and provides spacing in-between the parallel beams for the ducting of utility lines.  In a modification, the depressions may also include frangible mandrels which may be readily punched out of the concrete structure to enable the ducting of utility lines transverse to the beams of concrete.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE AMOUNT OF FUEL METERED INTO AN INTERNAL COMBUSTION ENGINE             ABSTRACT OF THE DISCLOSURE      Method and apparatus for controlling the amount of fuel metered to an internal combustion engine through electrically-controllable valve means, such as electromagnetic fuel injec-tors.  The valve means delivers the fuel to the engine in a quantity that varies as a function of an electrical signal representing the mathematical product obtained by multiplying a binary number electrical signal by an electrical signal representing a condition of the engine.  The binary number electrical signal is a coefficient of the engine-condition electrical signal and is calculated, by a programmed digital computer, from a function or functions describing a desired relationship between the coefficient value and various electrical signals representing variable conditions of engine operation.  The binary number electrical signal is repetitive-ly recalculated by the digital computer.  However, the product electrical signal is generated continuously or at a rate greater than the rate at which the repetitive calcula-tion of the binary number electrical signal takes place.          Consequently, with respect to variations in the engine-condition electrical signal, the product electrical signal used to determine the amount of fuel metered to the engine is up-dated continuously or at a rate greater than that at which the digital computer updates the binary number elec-trical signal.  If an engine condition that varies frequently and substantially, such as the engine intake manifold pressure or the mass of air flow into the engine, is repre-sented by the engine-condition electrical signal by which the computer-generated binary number electrical signal is multiplied, then a substantial improvement in engine control may be achieved because accurate fuel metering is possible during engine operation under transient conditions.

Abstract: ABSTRACT OF THE DISCLOSURE           Continuous wave (CW) output power from a gas trans-port laser is substantially increased without arcing by the use of a tubular cathode having a racetrack-shaped cross section and disposed in the main stream of gas flow through the laser channel transversely of the direction of flow and spaced above and upstream from a coextensive segmented anode in the opposite wall of the channel.  The racetrack-shaped cross-sectional configuration of the cathode provides maximum electrode surface for generating a glow mode electric discharge and also induces turbulence at that surface so as to support high current densities without arcing.  Continuous output power greater than 3.5 KW is achieved with improved efficiency with this electrode configuration.

Abstract: Abstract of the Disclosure Apparatus for automatically lifting containers, such as bottles, especially bottles from moving cases.  A series of closely adjacent, self-operating grippers are carried along an endless path above a moving case or cases to be emptied.  The grippers are laterally aligned with the columns of containers in a case and randomly grip the containers in an aligned row as they are guided into engagement.  The grippers yield upwardly if obstructed as they are guided toward engagement with containers, thereby permitting full depth cases to be emptied without co-ordinating a longitudinal relationship between and particular group of grippers and the case.         Each bottle qripper has two tong arms pivoted to each other and connected by links to a support for movement between a downwardly depending closed condition and an upward retracted open position.  A gravity-actuated detent is mounted in one tong arm and is adapted to move into engagement with the other tong arm.  The other tong arm has a recess or bore which the detent engages when the tong arms are in the retracted position so as to hold the tong arms in a retracted position after the grippers have deposited bottles on a receiving conveyor.

Abstract: THREE-POINT, AIR-BENDING SHEET METAL BENDER                   Abstract of the Disclosure A three-point, air-bending sheet metal bender comprising a pair of elongated U-shaped finger dies mounted parallel to one another is disclosed.  The elongated finger dies are mirror images of one another (when appropriately aligned) and, prior to bending, are spaced from each other by an amount generally equal to the thickness of the sheet of metal to be bent. The elongated finger dies are laterally position adjustable such that the "finger" of one die is alignable with the "palm" of the other die and vice versa; i.e., the finger of each die is alignable with the palm of the other die.  During bending, the "finger" die remains fixed and the "palm" die rotates.  As the palm die rotates, sheet metal located between the two dies is bent.  The direction of bending, with respect to the plane of the sheet of metal prior to bending, is determined by the die that is chosen to rotate.  A part support table is provided for supporting sheet metal parts and moving them into the space between the two finger dies prior to bending.  The part support table is arcuately movable in the plane of part insertion such that the part can be moved between the dies along axes transverse to the longitudinal axis of the finger dies, other than an orthogonal axis.  By sequentially moving the part through the dies, with a bend being performed subsequent to each such movement, a complex array of bends may be formed in a part prior to ejection from the bender.
