Abstract: Abstract of the Disclosure A discharge gate arrangement for railroad hopper cars having longitudinally extending discharge openings arranged in a horizontal plane beneath the hopper.  Gate members arranged in pairs swing in opposite directions trans-versely of the car.  Each gate member is pivotally hung and attached to an operating mechanism that includes a trans-versely extending shaft having two oppositely threaded por-tions.  The operating mechanism includes split nuts located on the threaded shaft portions with attached links connected to the gate members in order that rotation of the shaft in one direction moves the split nuts in opposite directions and causes the cooperating gates to open and close simultaneously.

Abstract: ABSTRACT OF THE DISCLOSURE           A double bypass, variable cycle gas turbofan engine is provided with a variable area bypass injector which varies the area through which the inner bypass stream is injected into the outer bypass stream.  The bypass injector comprises an upstream variable area, double bypass selector valve, the position of which determines whether the engine will operate in the single or double bypass mode, and a downstream static pressure valve which defines an optimum flow path for injecting the inner bypass stream into the outer bypass stream.  The ability to vary the area through which the inner bypass stream is injected into the outer bypass stream permits the static pressure valve to operate as an ejector and permits control of the two bypass air streams through creation of a static pressure balance at the exit of the variable area bypass injector.  The ability to control the bypass operating mode and the static pressure balance at the confluence of the two bypass streams eliminates the necessity for one exhaust duct and one exhaust nozzle, thereby reducing complexity and weight, and improves the engine-aircraft integration by reducing engine and nozzle diameters.

Abstract: ABSTRACT OF THE DISCLOSURE A strip of heated thermoplastic material is extruded from a die past first and second stations while the strip is drawn down between the die and the first station.  Initial cooling of the strip is performed at the first station and further drawing down of the strip is effected the first and second stations.  The strip is thereafter guided through a plurality of spaced convolutions about a journaled cylindrical member driven at a peripheral speed substantially equal to the linear speed of the strip as it enters the second station.  Substantial full cooling of the spiral strip is performed at the second station by a bath of cooling liquid through which the strip is linearly advanced and the strip is subsequently driven, at a linear speed substantially equal to the peripheral speed of the cylindrical member, from the second station into a third station in which the coiled strip is cradled between parallel rollers driven at peripheral speeds substantially equal to the linear advancing speed the coiled strip.  The cradled strip is subsequently  an-nealed during its movement through the third station by both internal and external sprays of heated liquid thereon.

Abstract: METHOD AND APPARATUS FOR IN-FLIGHT COMBUSTION OF CARBONACEOUS FUELS     ABSTRACT OF THE DISCLOSURE     An apparatus and method for combusting carbonaceous fuels includes a reaction chamber defining a reaction zone and means for inject-ing fuel and oxidizer gas in a manner to produce in the reaction zone a wheel-type flow of the fuel-gas mixture. In preferred embodiments, the high velocity wheel-type flow operates to suspend fuel or other reactant particles in the swirling gas for residence times required for substantially complete reaction of the particles prior to the particles impinging against the walls of the reaction chamber. High angular velocities and the resulting centrifugal forces operate to remove substantially all slag from the gas as it approaches the downstream end of the reaction chamber.          Operating temperatures are maintained at a level to avoid excessive volatilization of slag and thereby promote separation of liquid slag from the gaseous reaction products. Dense phase flow is employed for transporting pulverized reactants such as coal to the reaction chamber and injecting the reactants through a pintle fuel injector.

Abstract: ABSTRACT OF THE DISCLOSURE   A composition is provided herein which, when cured, provides an elastomer capable of conducting electrically.  It contains a particular class of cross-linkable organopolysiloxane and an electrically conductive lamp black.  The electrically conductive lamp black comprises from 15 to 60 percent by weight, based on the weight of the organopolysiloxane, of furnace black having a surface area of from 40 to 100 m2/g, and from 5 to 25 percent by weight of acetylene black, based on the weight of the organopolysiloxane.  The electrical resistance of the elastomer increases substantially faster with increasing temperatures, i.e., they exhibit a so-called PTC behaviour.  Since the steep increase in electrical resis-tance which takes place at lower temperatures can be predetermined, it is possible to attain a higher specific power density.

Abstract: ABSTRACT           A swimming pool wall is formed of inter-connected panels extending a substantial distance along the pool wall and upward for only part of the height of the wall which is formed of at least 3 tiers of panels.  The panels are formed of resin material to have an inward facing wall and flanges extending outward along top, bottom, and end edges.  The top and bottom flanges have mating tongues and grooves extending along the length of each of the panels to interlock the tiers together, and the flanges are connected to hold the tongues and grooves together. The flanges at the ends of the panels are intercon-nected and arranged so that the end joints in one of the tiers are located in central regions of panels in an adjacent tier.  A strengthener is fitted into a tongue and groove relationship with the lowermost of the bottom flanges to shape so that their substantial length cooperates when the panels are interlocked in tiers to conform the panels accurately to a pre-determined configuration of the pool wall.  For a cylindrical pool, the panels can be identical with the connected bottom and top flanges forming strong hoops of material extending around the pool wall.

Abstract: TITLE:    GAME HAVING MOVABLE OBJECT AND OBJECT STRIKING       MEMBER                          ABSTRACT            A game which can be used by either a sole player or preferably two players using the game in a competitive spirit is constructed to include within a housing a movable member.  Upon activation, preferably by the first player, the movable member travels down a guide path from a first position to a second position.  The second player then attempts to strike the movable member with a striking member.  If the second player's movements are coordinated with the motion of the movable member and the movable member is struck at the appropriate time, a chance wheel is activated.  The first player then controls the chance wheel by depressing a chance wheel stopping button which stops the chance wheel such that one of a plurality of indicia is exposed indicating the outcome of the second player's effect on the movable member.  This outcome is then recorded on an accumulator for maintaining a record of the game.  The movable member and the striking member are operatively connected such that the striking member is only capable of effectively striking the movable member when the movable member is in a predetermined striking position.

By controlling the addition of hydrogen peroxide with the variation of the pH value it is assured that sufficient hydrogen peroxide is added to attain a complete detoxication of the effluent  but that hydrogen peroxide is not wasted.
