Abstract: The Condiment Sprinkler is a spoon- or spatula-shaped device which provides a way for dry salt-type condiments to be evenly and effectively sprinkled onto food (in contrast to the “shaker” method). The Condiment Sprinkler comprises a generally convex bowl or open-ended shovel-shaped spoon and a handle, the shallow bowl (which may be round, ovate, or elongated) being somewhat flattened on the bottom and having raised ribs therein. The raised ribs may form a cross design. The raised ribs—whether they be in a cross design or some other appropriate design, such as ribs or bumps—serve to interfere with or dampen the centripetal and/or centrifugal forces generated when the sprinkler is waved, thereby impeding dumping or clumping of the salt-type condiment on the food. With use of the Condiment Sprinkler, the user can gain precise control over the salt-type material he/she is applying.

Abstract: A vehicle sensitive retractor control system having reduced sensitivity to Z-axis acceleration experienced during normal driving. The retractor control system incorporates a rolling mass and a locking lever which, in a resting position, are arranged such that the locking lever does not engage a ratchet wheel of a seat belt retractor spool. In response to accelerations in the horizontal plane, the rolling ball mass becomes unseated from its resting position and engages the locking lever, causing it to pivot and lock the retractor. In response to Z-axis acceleration, the rolling mass is prevented from contacting the locking lever by a mass restrictor. A soft damping spring is also provided to bias the locking lever against a lever rest. The spring is sized to overcome the inertia of the locking lever and prevent it from “bouncing up” and engaging the ratchet wheel in response to Z-axis accelerations.

Abstract: An aircraft 1 with a spiral inducing assembly 2 which is capable of inducing the aircraft to travel in a continuous spiraling motion without the aircraft rolling. A ramjet 6b is attached to a tube 3 that is able to rotate around the encircled part of the fuselage. The ramjet 6b is able to rotate in a pivoting manner on the rotate-able tube 3 with respect to the rotate-able tube 3, thereby changing their pitch relative to the longitudinal axis of the rotate-able tube 3. Ramjet 6b is smaller than another ramjet on the right side of the tube 3. The difference in size between the ramjets makes the ramjet 6b exert a weaker force on the rotate-able tube 3 than the ramjet on the right side when the ramjets are rotated in the same direction. The imbalance between the rotational forces thus causes the rotate-able tube 3 to rotate. A fin 6c is also able to cause the rotate-able tube 3 to rotate during flight. When rotated, the ramjets would exert a lateral force on the rotate-able tube 3.
