Abstract: A very simple and economic method and closure for quickly repairing a puncture in a vehicle tire utilizes a screw having a concave slot beneath its head. A sealing material such as an adhesive rubber is placed in the slot and is used to seal the hole when the sealing screw is threaded into the hole. The design provides easy, quick, efficient and very low cost repair for a puncture in a tire, not only for temporary repair but for long term repairs. The design is simple and includes only two parts: a screw having a spiral convex, or thread which affixes the screw in the tire and which further includes a concave slot under the screw head, and a sealing material such as adhesive or sticky rubber which is secured in the slot. The screw body is fixed in the tire hole and the head presses the sealing material onto the hole.

Abstract: A cooking device, comprises a base; a fulcrum mounted on the base; a support for carrying a pan, the support being mounted on the fulcrum and including first and second portions extending respectively from each side of the fulcrum a substantial distance; device for mounting the pan on the first portion; and an actuator operably associated with the second portion for periodically accelerating and decelerating rapidly the first portion about the fulcrum between first and second positions, thereby causing the pan to move upwardly and downwardly with the first portion and propel food placed therein into the air upon rapid upward deceleration and downward acceleration of the first portion and causing the food to be turned for uniform heating of different portions of the food.
