Abstract: A tilting projectile game that can be played by 1 to 4 people and consists of a base, 4 paddles, 4 paddle tilting assemblies and a spherical projectile. The paddle tilting assemblies connect the paddles to the base in a closely grouped 2×2 array and enable each paddle to be individually tilted in any direction while preventing the paddles from touching each other. 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. A control knob attached to each paddle is used to maneuver the paddle and control the motion of the projectile and can cause the projectile to roll or jump from one paddle to another.

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.
