Patent number: 4234788Abstract: Disclosed is an fiber optic scanning device that includes an optical fiber of predetermined length having one unsupported end for scanning, and having another end rigidly supported in a cantilevered fashion. The disclosed device operates to allow the movable end to be positioned with voltages that are substantially reduced over the prior art. To that end, an electrically conductive film lies on the fiber extending from the unsupported end to the supported end; and a transparent conductive plate lies in a plane perpendicular to the length of the fiber spaced apart from the unsupported end. This conductive plate forms a capacitance C with the conductive film. A voltage source V couples between the transparent conductive plate and the conductive film on the fiber to produce an electrostatic charge Q on the movable end of the fiber, where Q=VC. The movable end is positioned with a force F=QE by generating an electric field E transverse to the length of the fiber.Type: GrantFiled: April 6, 1979Date of Patent: November 18, 1980Assignee: General Dynamics Corporation, Pomona DivisionInventors: John P.

Patent number: 4232605Abstract: A warhead orientation device and its use in a directional attack mine are disclosed. The device includes a warhead launchable in a "pop-up" mode from a launch tube. The launch tube and warhead have a cooperating pin and helical groove system which imparts spin to the warhead during ejection from the tube. A stationary "fly wheel" type mass is attached to the spinning warhead. A cooperating pin and straight groove system on the mass and tube prevent rotation of the mass during ejection. This combination of spinning warhead and decoupled stationary mass provide a stable platform in one axis. Thus, suitable sensors and firing mechanisms may be used to cause a directional firing mechanism in the warhead to fire in a selected direction after pop-up.Type: GrantFiled: July 22, 1971Date of Patent: November 11, 1980Assignee: General Dynamics Corporation Pomona DivisionInventor: Clair K.

Patent number: 4178854Abstract: A system which disperses a payload in a sequential manner. The payload may consist of a number of discrete individual payload units which are composed of two or more sections. The illustrated and described embodiment of the system is utilized in a rocket for dispersing decoy material, such as aluminum chaff, in a sequential burst pattern so as to produce a more uniform, widespread distribution of the decoy material. This is accomplished by sequential bursts of each unit which throw outwardly the payload sections of each unit, whereafter each of the payload sections are exploded. This concept may readily be applied to mortor type decoy rounds, other types of decoy material, or to other types of applications, requiring a sequential dispersion of the payload thereof.Type: GrantFiled: December 22, 1967Date of Patent: December 18, 1979Assignee: General Dynamics Corporation, Pomona DivisionInventor: George H.
