  • Patent number: 5240206
    Abstract: An acrobatic airship capable of making a perfect somersault, and a 360 degree roll in a limited small air space, without utilizing high-powered thrusters or sophisticated automatic control mechanisms. The airship has a rather thick and round axi-symmetrically shaped hull equipped with a pair of reversible thrusters on each side of the hull's nose area. Each thruster is also equipped with a tilting mechanism, which enables the thrust vector orientation to be changed independently. The airship has a set of tail fins as attitude stabilizers which do not have movable control surfaces. This acrobatic airship can be designed as a manned or unmanned craft, and is ideal for use in advertising and also as a camera platform, an observation vehicle for hazardous environments, and in various other industrial applications.

  • Patent number: 5240129
    Abstract: A traveling crane incorporates a self-retracting/erecting live mast or the like, pivotally mounted on the base unit and capable of moving to and from a flipped, stowed position on the opposite side of vertical from the positions of the normal operating mode. A cable and winch is provided to raise and lower the mast during the normal operating mode and to move the mast toward the stowed position. A power cylinder operates to control the mast during retraction and to erect the mast from the stowed position. A control system operates the power cylinder to controllably move the mast during retraction/erection. Flexible pendants and telescopic guide links interconnect the cylinder with the mast and the base unit. Optimum operating angles are provided. The control system includes an electrical circuit and a hydraulic circuit, the hydraulic circuit having a restricted orifice to resist movement of the mast by gravity during retraction.

  • Patent number: 5238433
    Abstract: The present invention provides an improved outer surface for an upper region of an encasing arrangement for the outboard unit of a watercraft inboard-outboard propulsion system. Particularly, an independent casing is disclosed which has a relatively smooth, even and continuous outer surface and which is mountable upon a portion of such an outboard unit. The casing mounts in such a manner that its outer surface locates so that it is substantially flush with the outer surface portions of the outboard unit encasement which lie adjacent to the mounted casing. The lack of uneven surfaces, according to the arrangement of the present invention, makes the unit particularly useful in connection with activities which employ a line which is utilized to tow someone or something behind the watercraft, as the line will not snag upon the upper region encasing arrangement.

  • Patent number: 5238206
    Abstract: The rear hanging structure by which a turbojet engine is suspended from a mast under the wing of an aircraft includes a brace which is fixed to the mast and to which the engine is attached by at least three suspension links, the brace includes two parts which are fitted one within the other and are dimensioned in such a way as to ensure that each is able to take all of the suspension stresses independently of the other, the pins by which the brace is connected to the mast and to the suspension links passing through both parts of the brace. The redundancy thus achieved increases considerably the reliability of the suspension.

  • Patent number: 5236154
    Abstract: An improvement in an aircraft of the type having a passenger cabin, a wing with a wall defining a leading edge and having a vent/air intake opening therein and a conduit communicating between the vent/air intake opening and the cabin to provide ventilating air from externally of the aircraft to the cabin. The improvement is an air flow blockage plate that is removably fixed to the wing wall so that in its operative position the air flow blockage plate intercepts and deflects the flow of onrushing air directed towards the vent/air intake opening away from the vent/air intake opening as an incident of the aircraft moving forwardly relative to an air mass.

  • Patent number: 5236150
    Abstract: A way to make model/experimental planes crash proof by a shock absorbing harness mounted over the body of the plane, which does not significantly affect the flying abilities and qualities of the model/experimental.The harness protects against collision with ground or other objects by strategically placing shock absorbing structures on the body of the aircraft. These structures are protruding from the overall outer dimension of the model/experimental aircraft and are the ones to first hit external objects and the ground. These shock absorbing structures are made of material that is light and provides the resiliency and cushion against the impact to the model/experimental body. The design is such that they add very little weight and drag to the model/experimental aircraft. The structures are made of thin wires and resemble an inverted question mark in its basic configuration.

  • Patent number: 5235926
    Abstract: A pair of pivotally attached fins depend into the water below the hull of the boat. When turning maneuvers are executed the tendency of the boat to skid sideward is resisted by the downwardly engaged fin panels. The device provides improved steering control to all boats so equipped, but especially to outboard jet powered boats traveling in shallow water. When underwater objects or the bottom of a body of water are encountered, the leading edge of the fins strike the object(s), causing the fins to pivot upward to clear the obstacle(s) and then return automatically to the water to provide an extra measure of boating safety.

  • Patent number: 5236060
    Abstract: The invention is a conversion kit for converting a two-wheeled motorcycle into a three-wheeled motorcycle providing for increasing both the lateral and longitudinal stability of a conventional motorcycle while maintaining the conventional positioning of the motorcycle rider. The invention replacing the front wheel with a pair of opposed wheels connected to the conventional front fork by an elongated kit frame. The kit frame is narrow and does not provide for enclosing the driver within the frame. The elongated frame provides for greater longitudinal stability and the opposed front wheels provide for greater lateral stability. The kit frame is directly mounted to the conventional motorcycle front fork, requiring limited modification to the conventional motorcycle and eliminating special connectors required by prior designs.

  • Patent number: 5234181
    Abstract: A seat belt for a pilot seat or flight attendant seat in an aircraft includes a belt tightener with a reversible energy storage member in the form of a helical compression spring and a rod-shaped energy converter coupled to the energy storage member. The energy converter is at least indirectly connected to a belt member of the seat belt. After the belt member has been tightened and the energy converter has been displaced as a result with an at least partial regeneration of the energy storage member, a cutting chisel penetrates the surface of the energy converter and dampens the movement of the belt member. A renewed activation of the energy storage member after the deceleration phase is prevented by the penetration of a clamping edge of a clamping member in the surface of the energy converter.

  • Patent number: 5232184
    Abstract: A self-staging parachute apparatus including a drogue parachute and a main parachute each encapsulated in a respective packing bag with the main parachute packing bag defining a side pocket through which a specialized retention bridle extends from the suspension lines of the drogue chute directly to a load line connected to the load. The load thus utilizes a single point of attachment for both the drogue parachute and the main parachute with the retention bridle of the drogue parachute in movable engagement extending through the pocket of the main parachute deployment bag. The main parachute and drogue parachute when packed are designed to form a generally cylindrical shape which is adapted to be easily placed within cylindrical payloads such as flares or the like to facilitate deployment thereof after the rocket motor has been separated.
