TODAY’S PATENT- TOWING DEVICE
Today’s patent was invented by Nigel Axford on July 13, 2010 bearing patent no. US7752988B2.
The present invention relates to an apparatus that has improved stability during underwater towing and which helps to oppose destabilizing forces acting on the towed body. The invention proposes that the pivotable device with a wing generates a force on the body. By varying the orientation of the yoke relative to the body, the magnitude of the resultant force may be varied.
The resultant force tends to reduce the displacement of the tether relative to the pivot point in at least one plane, thereby generating a force to counter the buoyancy of the apparatus and so stabilize the apparatus when it is being towed. It is known for diving and stability of a buoyant underwater body using a yoke that is attached to the body approximately at its center. This helps to provide stable towing. The known towing devices do not counteract forces on the towed body that tend to destabilize the towing operation.
