  • Activated carbon material
    Patent number: 4111833
    Abstract: Activated carbon particles for use as iodine trapping material are impregnated with a mixture of selected iodine and potassium compounds to improve the iodine retention properties of the carbon. The I/K ratio is maintained at less than about 1 and the pH is maintained at above about 8.0. The iodine retention of activated carbon previously treated with or coimpregnated with triethylenediamine can also be improved by this technique. Suitable flame retardants can be added to raise the ignition temperature of the carbon to acceptable standards.

  • Joining wire-like members
    Patent number: 4057187
    Abstract: A device for use in joining wires such as electrical conductors is disclosed. The device comprises a ferrule, the exterior surface of which is covered with a coat or layer comprising an explosive composition. The method of joining includes coaxially aligning the end portions of two wires within the ferrule and then detonating the explosive composition to produce a metallurgical bond between the ferrule and each wire end. Apparatus for forming the novel splice is also disclosed.

  • Fiber distributed feedback laser
    Patent number: 3958188
    Abstract: Utilizing round optical fibers as communication channels in optical communication networks presents the problem of obtaining a high efficiency coupling between the optical fiber and the laser. A laser is made an integral part of the optical fiber channel by either diffusing active material into the optical fiber or surrounding the optical fiber with the active material. Oscillation within the active medium to produce lasing action is established by grating the optical fiber so that distributed feedback occurs.
