  • Patent number: 8479678
    Abstract: A bird repelling apparatus to repel birds from plants including a hanger, a round eyelet on a hanger second end, an initial ring loosely attached thereto, a thin diameter greater than 3 inches and 2 gauge thick first disc with a 0.2 inch diameter top aperture attached to the initial ring and a bottom aperture to which a round 0.75 inch diameter first memory wire ring is loosely engaged, and a 0.4 inch diameter jump ring loosely engaging the first memory wire ring. A second memory wire ring loosely engages the jump ring and a 0.2 inch diameter second disc upper aperture and has a 0.2 inch diameter lower aperture. The dimensions and the high gloss finish of the stainless steel discs are critical to the bird repelling function. Loose connectivity between the jump and memory wire rings and the discs provides liberal, relatively independent and unimpeded disc movement in a slight breeze.

  • Patent number: 6279254
    Abstract: A fan advertising device has a portable barrel with a fan, a pivotable or tiltable stand and a modified exterior fan housing. Metal fittings on the inside of the barrel, near the output end of the fan, allow for connection of metal inserts for accessories. The sock is held in place by a shock cord that fits into a groove on the exterior of the fan housing near the output end. A circular opening is located below the groove but above the fan to allow various objects, such as ping pong balls, to be placed into the airstream inside the sock. Those objects act as noise makers, attracting attention to and adding to the visual effectiveness of the sock. A light may be attached to the grate on the inside of the fan allowing for illumination of the entire sock. Illuminating the sock is useful for increasing visibility during darker hours.

  • Patent number: 5426878
    Abstract: An amusement device which includes a transparent tank filled with a liquid medium such as water. Contained within the tank is a plurality of uniform diameter, positive and negative buoyant spheres. Disposed inside the tank is a downward directional tubal system and an upward directional tubal system which are used to move the spheres in opposite directions of their buoyancies. Located beneath the floor of the tank is an air pump which feeds air into the tubal systems to create currents which forcibly move the spheres through the tubes. Also disposed in the tank are downward and upward directional tracks which route the spheres to their respective staging areas, depending upon their buoyancies. For example, positive buoyant spheres travel upward in the liquid medium along the underside of the upward directional track while the negative buoyant spheres travel downward in the liquid medium along the top side of the downward directional track.

  • Patent number: 5027539
    Abstract: Kites and airfoils designed in such fashion that the possibilities to observe the process by which the kite or airfoil is made airborne are maximized.Each time a gust of wind appears, the kite or airfoil rises automatically up a fixed pole which passes through it, without further direct intervention. When the airflow or wind abates, the kite or airfoil descends the pole, and rests on a restraining device located on the pole at a level higher than its lower-most level until the next gust of wind or an increase in the airflow lifts the kite or airfoil up again, and so on. The restriction of the pole also keeps the kite or airfoil within a short distance of the observer who can have a closer and better view of the process of ascension of the kite or airfoil up the pole.The applications of this invention include scientific instruments, childrens's toys and advertising devices. One embodiment of the invention is a kite which is designed to use the radio antenna of an automobile as its pole.

  • Patent number: 4928993
    Abstract: A splash guard for vehicles having a main panel of conventional splash guard form. The main panel is mounted on a vehicle behind the wheels to control splash. In association with the main panel is a secondary panel that is hinged on the back face of the main panel. The secondary panel is shorter and wider than the main panel so that the projecting ends act as wings and catch the air passing the main panel when the vehicle is in motion. The two panels carry separate indicia, with indicia on the main panel being normally hidden by the secondary panel until the air passing the main panel lifts the secondary panel to expose the indicia on the main panel. The splash guard may be used for displaying advertizing, slogans, humorous sayings or illustrations.

  • Patent number: 4864752
    Abstract: The invention concerns an improvement in a display member of the type comprising a plurality of reference members (14) accommodated within a common chamber (11) filled with an opaque fluid wherein each reference member is independently movable between a display position at which it is in face to face engagement with a display face (12) of the chamber (11) and a non-display position at which it is out of engagement with the display face. The improvement comprises each reference member (14) being associated with a boundary wall (19) which surrounds the sides of the reference member when at its non-display and/or display position. The function of the boundary wall (19) is to direct fluid entering or escaping from the space between the reference member and a face of the chamber adjacent the boundary member.

  • Patent number: 4693025
    Abstract: A display element including a sealed housing filled with an opaque, translucent or colored transparent liquid and having a screen therein colored on its front side and movable back and forth within the housing. The housing has a front transparent panel such that, when the screen is displaced in one direction, the colored front side of the screen is visible through the transparent panel. When the screen is displaced in the other direction, the colored front side of the screen is obscured or hidden from view by the liquid, which may be white or a color different from that of the screen. In one alternate embodiment, the transparent panel of the housing includes colored message indicia therein, which color matches either the liquid color or that of the colored front side of the screen, the other color contrasting. When the screen is moved in one direction, the message indicia disappears; in the other direction, the contrasting background color makes the message indicia readily visible.
