  • Patent number: 3970270
    Abstract: An aircraft capable of flying at very low velocities utilizing a wing envelope of an aerodynamic configuration having cells filled with a lighter-than-air gas. In one embodiment the buoyancy of the wing is slightly less than the total weight of the aircraft wherein forward movement is required to provide lift. In another embodiment the buoyancy is greater than the aircraft weight wherein forward motion is required to produce universal control without the release of gas or ballast. The wing envelope is formed of a plurality of trussed members radially extending from an axis producing a plurality of cells covered by a lightweight high strength skin material, the aircraft being characterized by high strength, economy and efficiency of construction and efficiency of lift at low speeds.

  • Patent number: 3953084
    Abstract: An electronic brake control for trailers utilizing solenoid operated electric brakes wherein trailer braking is controlled by sensing the rate of deceleration of the towing and towed vehicle producing an electric signal controlling a voltage controlled oscillator having a fixed frequency output and a variable pulse width, the pulse width increasing proportional to the rate of deceleration. The pulse signals are amplified and energize the towed vehicle electric brakes in an oscillating or pulsed manner to minimize skidding and brake locking. A light sensing circuit selectively shielded by a pendulum produces the automatic deceleration responsive signal, and manual apparatus are employed to produce trailer braking without braking of the towing vehicle. Additionally, the automatic electric brake system control through the brake light circuit is by-passed and isolated by actuation of the emergency warning brake light system.
