Abstract: A device to make the insertion of a beach sun umbrella into the sand easier and faster, by adding a second piece of metal tube, of slightly larger diameter than main stem A, about 25 inches in length and placed over the lower part of the main stem A, like a sleeve. The bottom of this tube B is cut, to form teeth that will cut the sand, when this tube B is rotated by a hand held cordless electric motor and secured in place by the brackets, which also hold tube B secure and cushion (i) of stem A support A conical gear ring (d) is secured at the top of tube B and a ring (f) also secured in main stem A, which with the brackets (h), (j) and (k) hold all the parts in place, for good operation.

Abstract: A device for enhancing the maneuverability of motorboats and motoryachts includes a high velocity water jet pump (HVWJP) attached to the main engine through an electromagnetic clutch. High velocity water flows from the HVWJP's outlet to bow and stern side nozzles, through solenoid valves, individually controlled from the cockpit. The benefits of the device are that turns and lateral movements will be easier and faster, and extra power for fire fighting and emergency bilge water pumping are also available. Further, if the yacht, while speeding, strikes a rock or other submerged obiect and the propellers and shafts are destroyed, the crew will use the U section pipe to connect the NVWJP's outlet to an auxiliary propulsion pipe, demonstrate to the tug's skipper that his yacht is not a dead ship on the water, and legally claim and pay the towage fee, instead of the far more expensive salvage fee.

Abstract: A device that will automatically energize an Alarm Box, when an Over Navigable Water Bridge Section (ONWBS) collapses, said devise comprising two electric switches, each having two contact legs, one leg embedded steady on the base and the other leg free swinging on a pin. A spring is properly attached to keep the two legs closed, when free.

Abstract: An adjustable length bar to replace the rigid bar, the one connecting the two outboards or the two outdrives of a boat, for steering purposes, said adjustable bar being electricly operated through a switch on the boat's dashboard, said switch having two operating positions, one to keep propellers creating two parallel thrusts (cruising mode), and a second to shift the propellers to create a vee configuration (maneuvering mode), by which the boat's maneuverability will be enhanced.
