Abstract: A stabilized antenna system is disclosed. The stabilized antenna platform includes an acceleration displaceable mass which compensates for linear acceleration forces to inhibit tipping of the antenna platform. The stabilized antenna system may include in combination a gimbal mounting and one or more gyros.

Abstract: An interconnect system from a combination gyro and pendulum weight passive stabilization system unit and an equipment platform, such as an antenna platform, whereby the platform is position stabilized in pitch and roll as controlled by the passive stabilization system unit. The interconnect system may take the form of a selsyn system used with a generator and a motor interconnected by multiple wire circuitry to permit location of a passive stabilization system unit at an ideal location in an ocean-going ship, such as in the epicenter region of the ship, with minimized pitch and roll acceleration forces, and with the antenna platform stabilized thereby ideally located for antenna purposes as much as hundreds of feet away from the passive stabilization system unit.

Abstract: A multi-axis antenna pedestal with two controlled axes configured with elevation over azimuth on a gravity and gyro stabilized platform. The assembly is suspended with right-angled pivotal axes in substantially the same horizontal plane, and structure pivoted about the upper two controlled axes is statically balanced and the center of gravity of the entire pivotally mounted assembly is on the vertical axis and below the gimbal plane. The platform structure includes at least one gyro motor and rotor system pivotally mounted in the platform structure on an axis parallel to one of the right angled pivotal axes of the platform pivotal mounting. The center of gravity of the one gyro motor and rotor system is below its pivotal mounting in the platform structure, and when two such gyro motor and rotor systems are employed the pivotal mounting axes of each parallels an individual axis of the platform pivotal mounting.

Abstract: A plankton harvester includes a surface float adapted to be secured to face tidal flow with an open subsurface cylinder secured to the flat and with the fore/aft axis parallel to the axis of said cylinder. A rotatable conical net structure is coaxial with the cylinder with the apex thereof at the mouth of the cylinder and the cone base engaging the opposite end to force fluid passing through the cylinder to pass through the net and deposit solids from the fluid on the surface of the net. Vanes in the conical structure rotates the cone at a rate dependent upon flow. Powered suction means adjacent to a linear surface segment of the net removes solids from the net surface. A storage chamber associated with the float is flow coupled to the suction means to store solids removed from the net surface.

Abstract: The specification discloses a transmission for varying the mechanical advantage in the power train of a bicycle. The transmission includes a drive sprocket attached to one wheel of the bicycle for driving the wheel and a fixed pitch sheave mounted on the bicycle frame. An endless chain is entrained between the drive sprocket and fixed pitch sheave. A rotatable variable pitch sheave is mounted to move relative to the fixed pitch sheave and is operatively connected to the fixed pitch sheave by a V-belt passing therebetween.A pedal sprocket is rotatably mounted on the bicycle frame and connected by way of a chain to the variable pitch sheave for rotating the variable pitch sheave. The rotation of the variable pitch sheave by the pedal sprocket causes the movement of the variable pitch sheave relative to the fixed pitch sheave to vary the mechanical advantage therebetween.
