Abstract: ABSTRACT OF THE DISCLOSURE           A portable, table type miniature golf game consisting of a game board made of easily and quickly assembled sections to take up minimum room when not in use.  The game board has the configuration of a cross with the and of the main leg remote from the cross leg defining the starting zone of the play.  Upstanding side walls are fixed to the edges of the panel and confine the golf ball to the playing surface.  There are three cups made in the cross leg.  One cup is visible from the starting zone, while the two remaining cups are not visible, the side walls forming an obstacle.  The cups can be selectively plugged so that only one is used at anyone time.         Various hazards of different shapes can be removably positioned from the playing surface and their positions can be changed.  Ball deflectors are also removably attached to the walls.  A fortune wheel is associated with the game and determines by chance the number ofr points to be scored if the player sinks the ball in the cup in the indicated number of strokes.

Abstract: ELECTRONIC TONE-GENERATING SYSTEM     Abstract of the Disclosure A tone-generating system for an electronic musical instrument of the percussion type is provided wherein an audible tone closely approximating the corresponding tone of a conventional instrument is generated electronically,  A single-pole, double-throw switch is actuated by a key to ini-tiate generation of the tone and a tri-level detecting circuit coupled to the switch is utilized to determine which of the three states the switch is in; that is 9 the two "throws" or positions of the switch which correspond to the released and depressed positions of the key, and the state in which the switch is between the other two positions. By detecting the three states and developing corresponding control signals, counting circuitry may be utilized to determine the intensity with which the key is depressed to enable generation by a read-only memory of digital scaling signals representative of the variations in amplitude of the initiated tone with respect to the intensity with which the key is depressed.          An envelope control counter responds to the control signals and a variable rate clock to drive an envelope generating read-only memory to generate a digital envelope signal,  A master frequency generator comprising an oscillator and divider circuitry is used to generate a digital pulse train representative of the frequency spectrum of the initiated tone,  The digital scaling signal and digital envelope signal are combined in a multiplying digital-to-analog converter to obtain a corresponding composite signal.  The composite signal is integrated to improve its analog characteristics and then it is applied to an output gate wherein it modu-lates the oscillating signal to produce an electrical signal representative of the initiated tone.  The composite signal may be filtered and amplified by appropriate circuitry and then audibly reproduced by a loudspeaker.  In the multiple-tone embodiments of the invention, multiplexers are utilized to reduce the amount of circuitry duplication and inter-connecting wiring.     -1a--

Abstract: POWER INFEED FOR CHIPPERS                   ABSTRACT OF THE DISCLOSURE A chipper infeed spout incorporating two surfaces disposed to form a V-shape having one side formed by a pair of support means (an anvil member and preferably a roll).  A driven power roll is moveable across the direction of travel of the log along said spout and tends to align the log and force it against the pair of support means whereby the log forms a beam freely supported (by the support means) and having a concentrated load (power roll) interposed between the supports.  Preferably the power roll is oriented to apply forces to a log not only to tend force it against the two spaced supporting means but also to force it toward the apex of the V of the V-shaped supporting surfaces.  When the chip-per is used as a slab chipper it is preferable to form one of the support means by a driven roll that is arranged at an angle and driven in a direction to tend to lift the side of the slab that contacts the roll whereby the movement of the power roll tends to align the major dimension of the slab flat against roll and thus the anvil number.

Abstract: METHOD FOR THERMALLY KILLING      ROOTS IN SEWER LINES               Abstract of the Disclosure This invention relates to a method for using a heated fluid as a thermal herbicide for scalding and killing roots growing within sewer lines.  The process includes the steps of heating a fluid, isolating a length of a sewer line, and then filling the isolated length of sewer line with the heated fluid for a lethal period of time required for the heated fluid to act as a thermal herbicide for killing the roots within the length of sewer line.  When treating an adjacent length of the sewer line, the preheated fluid is removed from the preceding section, reheated, and then inserted into the adjacent isolated length of the sewer line.

Abstract: ABSTRACT           A hydraulic coupling of the temperature responsive type and particularly adapted to couple the engine to the radiator fan of an internal combustion engine.  The specific improvement resides in a rolling dam adjacent the dump hole which connects the outer portion of the drive chamber con-taining the drive rotor with a shear liquid reservoir passageway.  The dam rolls between two abutments carried by the housing cover so as to assume either of two positions with respect to the dump hole.  One position of the dam relative to the dump hole accommodates relative rotation between the drive rotor and coupling housing in one direction, the other position of the dam relative to the dump hole accom-modating such relative rotation in the other direction.  The rolling dam automatically moves to the proper position relative to the dump hole upon either direction of relative rotation between the drive rotor and coupling housing.

Abstract: ABSTRACT OF THE DISCLOSURE     Copper, iron, and lead impurities are removed from molybdenum flotation concentrates by mixing the feed concentrates with a nonvolatile chloride salt, heating the mixture to a temperature of from about 200°C to 350°C for a time sufficient to activate the lead impurities in the concentrates so that they can be leached therefrom during the subsequent leach step, and leaching copper, iron, and lead impurities from the heat-treated concen-trates with a mildly oxidizing leach solution containing chloride ions and having a pH of no more than 4.  Prefer-ably, the mixing of the chloride salt and the feed concen-trates is achieved by thoroughly mixing an aqueous solu-tion of the salt with the feed concentrates.  It is advan-tageous to use an aqueous ferric chloride solution to leach the heat-treated concentrates inasmuch as the lead values leached from the concentrates are readily crystallized from the pregnant leach solution and the resulting spent solution can be recycled without further treatment to be mixed with the feed concentrates, or it can be treated to oxidize ferrous values therein to ferric and then recycled for repeated use as regenerated leach solution.

Abstract: ABSTRACT OF THE DISCLOSURE   A method of measuring the amount of substance associated with a material in the presence of a contaminant comprises choosing a first band of radiation which lies outside the absorption band of the substance but within the abosrption band of the contaminant.  The first band is directed at the material; a first detector is positioned to receive the radiation after impinging the material.  The first detector converts the radiation received into a first electrical signal.  A second band of radiation, which is chosen to lie within the absorption band of the substance, is also within an absorption band of the contaminant.  The second band is directed at the material;  a second detector is positioned to receive the radiation after impinging the material.  The second detector produces a second electrical signal in response to the radiation received.  The second electrical signal is subtracted from the first electrical signal.
