No. 19848.—8th August, 1905.—EDWARD JOHN CHAMBERS, of Manor House, Tettenhall, near Wolverhampton, England, Civil and Mechanical Engineer. Improvements in or additions to pipes or tubes and the like for containing underground electrical cables or conductors.

Extract from Specification.—In carrying this part of my invention into effect I bridge or connect the ends of the pipes projecting into the junction or like box by means of an electrical conductor, preferably a copper, lead, or other soft and not readily oxidizable metallic strip, the electrical connection of the ends of the metallic strip conductors with the ends of the pipes being effected preferably in one of the ways described constituting a further part of my invention. In applying my invention to cable-containing pipes in junction and other boxes already in position or use I take a metallic strip having preferably a width of about three-quarters of an inch and a thickness of about one eight of an inch; I clamp the ends of the strip on to the collars of the spigot ends or on the barrel part of the pipes in the junction and other boxes by clips in two or more parts, closed on the said collars or barrels by means of screw-bolts, pins, cotters, rivets, or other equivalent means of fastening.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

Claims.—(1.) A vacuous vessel having in it two conductors adjacent to but not touching each other, one of them being heated, these conductors being connected by a circuit outside the vessel, such circuit being exposed to some influence tending to produce an alternating current in it and which contains a galvanometer or other instrument for detecting a continuous current, substantially as described. (2.) In instruments such as are covered by claim 1, heating the conductor by means of a continuous electric current passed through it, substantially as described. (3.) The application of the instruments covered by claims 1 and 2 to wireless telegraphy, substantially as described. (4.) Duplicating the instruments covered by claims 1, 2, and 3 by connecting the two coils of a differential galvanometer respectively to the heated conductor in one vessel and the unheated conductor in the other, the connection between the two coils being connected to the other pair of conductors, substantially as described. (5.) Instruments for converting alternating electric currents into unilateral currents, substantially as described.
