Latest Patents
One of his latest inventions is a propellerless scuba propulsion vehicle powered by a compound piston motor. This innovative design features opposing water thrusters that provide divers with air without limiting their dive time. The scuba tank's compressed air powers a dual piston compound motor, driving dual water thrusters for steady underwater propulsion. The motor's exhaust supplies breathing air to the diver through a demand regulator, allowing for continual and powerful thrust without curtailing normal tank dive time. This lightweight vehicle can be strapped to the scuba tank for hands-free operation or held by the diver for maneuvering through the water. The diver can control the on/off function and variable speed with a simple throttle control, eliminating the need for a propeller or battery.
Another significant invention is a tire repair apparatus. This device features a tire repair plug that is stretched in an insertion tool and inserted into a bored-out tire injury. The plug includes a cylindrical stem and a conical head at the leading end. A circular transverse opening is located slightly axially interior to the leading end of the stem, with a bearing surface at the bottom to prevent the plug from sliding off the insertion tool. A transverse slit extends from the transverse opening to the trailing end of the stem, bisecting it into two halves with semi-circular cross-sections. The outer surface of the cylindrical stem and the inner walls are covered with a cushion gum sheet, which is protected until the plug is ready for use.
