Antiballistic Missile Targeter

Relates to the alteration movements of mounting tables, for use in targeting missiles, aircraft, and targeting of robotic appendages.

Numerous proposals for positioning targeting tables have been developed using electromagnetic fields to change table positions, and spring loaded teeth upon gear teeth to eliminate slack in mechanical drive trains.

A need to target distant moving objects, and those within immediate proximity such as artificial limbs are considered imperative to use such methods where the drive train has no moving parts, and hence no play between driving mechanism and driven mounting plate.

Accordingly there exists a need to combine rigid direct motion with rapidity in change of attitude of mounting plate repeatedly. The device of the present invention fulfills these three foregoing objectives.

The present invention takes advantages of the qualities of nitinol alloy wire stretched near the limit of its breakdown; and has the two ends of its length attached one end to the base of a cylinders rim edge, the other end of its length is attached to a disk with a hole in its center within which the convex end of the cylinder protrudes so as to allow the disk to pivot upon the convex lip end of the cylinder. Whereupon the plurality of wires stretched longitudinally around the cylinder, each wire termination being fastened with an insulator to prevent wire contact to the cylinder and disk so forming individual conductors, are then connected to individual rheostats ultimately controlled by computer coupled microwave radar. Each wire's rheostat input voltage correlates with target position integrated from computer coordination; thereby causing resistive contraction in length of particular wires in concert with all other wire inputs thus causing divergence of the disk mounting plate appropriately. The nitinol alloy which returns to original length when heated and associated mechanism of mounting plate ideally is within an enclosure partially evacuated with residual appropriate gas mixture combinations to cause efficient dissipation of heat from wire into gas molecules moving within the partial vacuum, or liquids to conduct heat away.

It is therefore an object of the present invention to eliminate freeplay slack from the drive train of movable targeting tables.

It is another object to cause divergence of a mounting table through resistive heating of suspension elements.

It is another object to directly correlate position into linear corresponding resistance.

The novel features which are believed to be characteristic of the invention, both to its organization and method of facilitating targeting together with further objectives and advantages thereof will be better understood from the following description considered in connection with the accompanying drawings in which a presently preferred embodiment of the invention is illustrated by way of example. It is to be expressly understood that the drawings are for the purpose of illustration and description only, and are not intended as a definition of the limits of the invention.

FIG. 1 is an illustration of a device embodying the present invention from a side perspective view showing the stationary cylinder and movable pivot disk with plurality of stretched nitinol wires arranged longitudinally between the disks outer edge and the end of the cylinder; and the terminations of all wires connected to the rheostat controller radar computer.

FIG. 2 shows alternative embodiment with levers between the nitinol wire end and the movable table disk edge.

While this invention is susceptible of embodiment in many different forms, there are shown in the drawing and will be described in detail, preferred embodiment of the invention. It should be understood, however, that the present disclosure is considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated.

The precise shape and sizes of the components described are not essential to the invention unless otherwise indicated. The apparatus of this invention may utilize certain conventional cable tension control mechanisms, the details of which will be apparent to those having skill in the art and an understanding of the necessary functions of such mechanisms.

FIG. 1 shows stationary cylinder 4 with disk 2 sitting upon it, and convex end l protruding through it as its pivot; stretched nitinol wire 3's are connected to insulator point 9's at the edge of disk 2 and the end of cylinder lip 5. Individual rheostat connections from computer are 6's, and 10 represents the common ground lead for 's connections to computer voltage controller 7 and microwave sensing mechanisms 8.

FIG. 2 shows a side cutaway view where a base for mounting the device is letter F and a central pivot B holds up movable mounting plate A, flanking each side are fulcrums C with their pivots E; letter G details point of intersection where fulcrums leverage is communicated to movable table A, nitinol wires D actuate the movement of the fulcrum to multiply the force upon the movable table A, connection leads H ultimately lead to individual rheostats resistive heating for contraction and alternate relaxation of wire length, table I is stationarily attached to table A that they may move together as one; radius J serves as a seat upon which o-ring K travels upon, o-ring K is a direct extension of table I's perimeter in serving as a vacuum seal to containers L ability to retain the partial vacuum within it labeled M.
