  • Reflected three dimensional display
    Patent number: 4180930
    Abstract: Half of two symmetrical portions of an object to be displayed, is cut or embedded in one surface of a block of transparent material. The surface of the block in which the symmetrical half of the object is cut or embedded, is made reflective, so that a person viewing the block of transparent material sees the cut or embedded half together with reflections of that half to obtain a view of the composite halves of the symmetrical object. The arrangement is such that when the profile part of a human portrait is cut or embedded in the block, a viewer will see the entire head of the portrait, and not only the profile part. The reflections providing the image of the other symmetrical half of the portrait which is not cut or embedded in the block.

  • Perforated stencil sign panel
    Patent number: 4180934
    Abstract: A marquee false front consists of a sheet of pennant cloth of one color, e.g. yellow, of dimensions equal to those of the desired marquee false front.

  • Bubble blowing wand
    Patent number: 4180938
    Abstract: A bubble blowing wand for use with a bubble blowing liquid comprising two substantially concentric rings for providing a bubble or bubbles formed within a bubble. The concentric rings are substantially in the same planar relationship with respect to each other. The rings can be substituted with any closed geometric form so long as the peripheries are implaced within each other in a substantially spaced concentric relationship. The preferred concentric rings are formed as a larger outside ring and a smaller inner ring. The larger outside ring is attached to a handle at its outer edge, while the inner surface thereof supports a stem to which the inner ring is connected. Both of the rings have relieved or cut surfaces providing a larger surface area on the rings to accommodate greater amounts of bubble blowing liquid.

  • Lighted and sounding toy
    Patent number: 4178714
    Abstract: A lighted and sounding yo-yo is provided with a single heavy duty battery in a first hollow shell section, and a lamp in both hollow shell sections. Flexible electrical conductors connect the lamps to the battery. A centrifugal switch is joined with the conductors in the second shell section so as to actuate the lamps only during rotation of the yo-yo. An audible electrical signal device is also located in the lighting circuit of the second shell. A second modification of the centrifugal switch is also shown. The heavy weight of the battery shell as compared with the light weight of the other shell causes the battery shell to dominate the yo-yo in the manner of a gyroscopic action to obtain rotational stability.
