  • Pivoting target array game
    Patent number: 4116443
    Abstract: A game apparatus includes an array of paddle-type display elements rotatably mounted in a housing, with the paddles of the display elements having suitable indicia thereon. The game may be played by actuation of selective display elements in tic-tac-toe fashion, with actuation of the paddle elements being preferably effected by tossing small bags against selective paddles. The array of display elements is arranged in a series of rows and columns in a body structure, with each display element being rotatably mounted about a shaft secured to the body structure. Each display element preferably comprises three radially extending planar portions radiating from a central hub, and an aperture is provided in the hub to which the associated shaft extends. Each aperture defines in cross-section an isosceles triangle.

  • Devices for probing by ultrasonic radiation
    Patent number: 4117446
    Abstract: N elementary transducers are distributed regularly along a line of scanni An ultrasonic frequency receiver is associated with phase lag means. The distribution over n successive elementary transducers of the phases corresponding to focusing at a predetermined distance or several successive distances from the line is stored. That distribution corresponds to several Fresnel zones. Switches first connect a generator to a group of n' transducers corresponding to the central Fresnel zone of said stored distribution and later connect a group of n transducers to the receiver direct and via the phase lag means according to the stored distribution(s). The groups of n' and n elementary transducers are shifted along the line at intervals of time. The phase lag means may consist of inverter means causing a phase angle of .pi..

  • Apparatus for producing high-melting-metal-oxide-based crystalline materials
    Patent number: 4116598
    Abstract: Apparatus for producing high-melting-metal-oxide-based crystalline materials by melting a charge under the effect of a high-frequency electromagnetic field with the charge melting zone being maintained constant, the charge being loaded continuously and obtained crystalline material being withdrawn also continuously. The apparatus is a cooled mould, whose body is shaped as a truncated cone with an angle between its generatrix and cone height ranging from 2.degree. to 10.degree., and an induction coil encompassing the body of the cooled mould in the region of location of the constant melting zone.

  • Secondary lead smelting process
    Patent number: 4115109
    Abstract: A process for producing metallic lead from lead battery plates and other types of lead scrap in a secondary lead smelting operation has been developed which comprises adding from 1% to 8% moisture and 0.5% to 5% oxygen to the air which is used to react with carbonaceous material such as coke to maintain the temperature in the melting region from about 1100.degree. C. to about 1300.degree. C. The moisture is added to the air to react with the coke to form carbon monoxide and hydrogen, and the oxygen is added to maintain the temperature in the melting zone. Increased amounts of lead are produced using smaller quantities of coke and iron when the moisture and the oxygen are added to the air.

  • Rotary harrow with pivotable coupling assembly
    Patent number: 4114695
    Abstract: An implement has an elongated frame that extends transverse to the direction of travel and soil-working members rotatably mounted on a portion of the frame that depends from spaced apart, forward and rear frame beams. A coupling assembly having coupling points for auxiliary implements is pivoted to the forward frame beam by two beam members that extend rearwardly and rest on top of the rear frame beam to limit the downward movement of the assembly when the implement is raised. The rear ends of the beam members are connected to a tubular beam and further beams extend rearward from the tubular beam. A transverse beam interconnects the further beams centrally thereof and coupling points such as hooks are adjustably connected to plates that depend from the further beams. A central coupling point is fastened to the transverse beam and the further beams are adjustable to vary the width of the assembly.

  • Apparatus for conninuting solids in liquids
    Patent number: 4114815
    Abstract: A homogenizing mechanism for a manure slurry in combination with a supply container and blades adapted to penetrate about fifteen centimeters under the soil surface for injecting manure into the soil by an injection pipe carried by the blade. The mechanism is disposed between container and the injection outlet so that the injected slurry must pass therethrough. An air displacement pump selectively places the container under pressure (up to about one atmosphere) or vacuum for moving the slurry out of or into the container, respectively. The homogenizing mechanism has a substantially cylindrical casing with an inlet from the container on one end and an outlet leading to the injector at the other end. The inlet may be a conduit or an open end of a casing mounted in part within the container.
