Abstract: This is an improvement to the tilting projectile game of U.S. Pat. No. 7,543,818 B2, in which the tilting assemblies that connect the paddles to the game's base and allow the paddles to tilt in every direction while preventing the paddles from touching one another, have been strengthened, simplified and made more efficient by replacing relatively complex parts with a single, stronger and simpler piece. By enclosing the space between the paddles and base, this improvement also ensures that players cannot put their fingers between those moving parts when the game is being played, whereas in the game's original design, if a player did not hold the paddles in the proper manner, they could misplace their fingers into that space.

Abstract: An electronically controlled water clock designed to visually display the passage of hours, minutes and seconds by the gravitationally induced flowing away of liquid material inside transparent vessels, with each unit of time displayed in a separate vessel. Each vessel consists of an upper and lower chamber and an air tube connects the 2 chambers to equalize air pressure between them and to serve as an overflow drain for the upper chamber. The bottom end of the upper chamber has a small drain tube through which the liquid drains out. The front of the upper chamber is inscribed with a uniform scale and its interior shape is such that the upper surface of the liquid drops in equal vertical intervals over equal time spans throughout the entire time required to drain the upper chamber from the top to the bottom end of the scale.

Abstract: A tilting projectile game that can be played by 1 to 4 people and consists of a spherical projectile, 4 rectangular paddles, 4 paddle tilting assemblies and a base. The paddle tilting assemblies connect the paddles to the base in a rectangular, 2×2 array, with a narrow gap separating the interior edges of the paddles. The paddle tilting assemblies enable each paddle to be individually tilted in any direction while preventing the paddles from touching each other. Rails on the outer edges of the paddles form a rail along the perimeter of the 2×2 paddle array that is used both to control the movement of the spherical projectile and to prevent the projectile from falling off the outer edges of the paddles. Each paddle has one or more holes, which are large enough for the projectile to pass through, and the base is shaped to channel the spherical projectile into retrieval areas at the ends of the base after the projectile has fallen below the paddles.
