  • Patent number: 4266360
    Abstract: An artificial bait of the type of a hollow, transparent body having a front, blunt portion, wherein the front or head portion of the bait is of a color distinct from that of the rest of the bait. The main body color of the bait is provided by a sheet-like insert in the body extending from the rear end to a point spaced from the end wall of the head portion. The front end wall is preferably concave and is provided with a paint layer, preferably applied to the exterior. Since both the front wall and the rest of the body is moulded from a transparent plastics material, the color of the paint applied to the front wall is also displayed at the side wall of the body. Accordingly, the color of the front portion, preferably red, is visible not only in front view but also at virtually any angle of viewing of the bait, except the exact rear view.

  • Patent number: 4239421
    Abstract: A blending chamber silo for pulverized bulk material has a main silo chamber with an inlet in its uppermost region, and a centrally located blending chamber on the floor of the silo has a roof and side walls with bottom apertures therein for the influx of the material from the main silo chamber into it. Aeration apparatus and air inlets are provided for the silo floor, and separate homogenization aeration apparatus is provided for the floor of the blending chamber, which operates under a pressure higher than that of the silo aeration apparatus. The roof of the blending chamber is spaced well below the top of the silo, and the blending chamber has a diameter substantially smaller than the diameter of the silo, whereby the lower portion of the silo wall and the wall of the blending chamber define a semi-annular narrow space having a height to width ratio greater than 1:1 and which breaks up material compacted or formed into bridges in its downward path toward the bottom apertures of the chamber.

  • Patent number: 4231250
    Abstract: An apparatus is disclosed for the continuous measurement of the level of liquid in a container, wherein a flexible cable extends into close proximity or engagement with the floor of the container and comprises the oscillation determining element of an oscillator. The cable has a length greater than the distance between its mount to the container and the bottom of the container, and is doubled over at least part of its length to form an arc or loop at the container floor. A support engages the cable adjacent the container floor and holds the cable so that the arc or loop maintains its position relative to the container floor even though the container floor may sag or bulge, or the spacing between the floor and top of different containers varies because of manufacturing tolerances and the like.
