Abstract: The electronic winterizer is a device that is installed in the interior of a boat. It winterizes an inboard/outboard engine without the use of a person knowledgeable of this process. It can be accomplished in or out of the water. The invention allows a boat owner to operate his inboard/outboard engine in cold temperatures without having to employ a person to winterize the engine each time he uses it. Thus it is made useful all winter. To operate, the inboard/outboard engine is first started. After the engine reaches an acceptable temperature, the thermostat is opened. While the engine is running the operator turns on a switch that is mounted in the dash of the driver's console. The switch activates an electronic timer that operates a DC powered valve and pump. At the time of operation the valve opens and the pump starts. The pump drains antifreeze from a holding tank that is also installed in the boat's interior. The pump dispenses antifreeze through the open valve and into the injector.
Abstract: A minesweeping system, self-contained within the water vessel sought to be rotected against contact-actuated moored mines, effective against moored mines which are directly in the path of the vessel, featuring a beam-and-float arrangement. A ruddered float is maintained by a control system in virtually forward position with respect to the vessel and is attached at the fore end of a long boom beam, the aft end of which is pivotably attached to the bow of the vessel. A depressor for maintaining submergence of the lower end of the tow wire and the inward ends of the sweepwires is attached at the lower end of the tow wire, the upper end of which is attached to the beam near the float. Port and starboard sweepwires are attached to the tow wire near the depressor, each sweepwire projecting generally horizontally and backwardly obliquely. Diverters attached at the outward ends of the two sweepwires maintain their proper orientation. Cutters are situated along the outward ends of the sweepwires.

Abstract: A roller skate wheel is constructed for rolling in both the forward and lateral directions of the skate. A plurality of rollers are mounted on the wheel hub, each roller rotatable about an axis tangential to a circle on the wheel axis. The rollers conform to a second circle on the wheel axis for contact with a skating surface. Application of friction to the rollers controls the resistance to lateral rolling, thus providing a braking action to the skater.
Abstract: An improved flexible boot 20 is provided for protecting aircraft operating mechanisms such as bearing 18 from foreign objects such as sand and dirt. The boot 20 has a slit 30 and an associated resealing arrangement 39 which allows the slit 30 to be resealably closed. The resealing arrangement 39 thus enables the protected mechanism or bearing 18 to be inspected without removal of, or damage to, the boot 20 while still allowing the boot to retain its ability to protect the bearing 18 from foreign object damage. The preferred resealing arrangement 39 is of the hook and loop type which is sold under the registered trademark Velcro.RTM..
Abstract: An amphibious vehicle has a hull with a seat portion formed on its upper side. An operator seated upon the seat would straddle the hull. The hull has a flotation body for buoyancy and four hollow, cylindrical wheels also contribute to the buoyancy. Handlebars are used to steer the wheels and to operate a rudder so that the amphibious vehicle may be operated on firm, sandy, soft, and liquid surfaces. The wheels have vanes which radiate outwardly and curve counterclockwise, viewing each wheel in the foreground and the hull in the background. This causes the vaned wheels to grip soil or mud and to channel water rearwardly to propel the amphibious vehicle forwardly. The vehicle is propelled by a pedaling mechanism.
