Abstract: ABSTRACT OF THE DISCLOSURE A protective fuse comprising a fusible element disposed within an enclosure formed by a gas generating fiber tube connected at one end to a conductor rod and at the other end to an arc intercepting member. The arc intercepting member is connected to an elongated tubular resistor element which in turn is connected at its opposite end to a cap comprising a conductor connected to the fusible element. Upon parting of the fusible element an arc established by the fault current comes into contact with the arc intercepting member so that a circuit is established through the resistor element thereby momentarily reducing the fault current to a level which can be extinguished by the deionizing gases generated within the interior of the fuse. The conductor rod is formed of a magnetic material which is capable of generating a substantial magnetic flux which functions to bias the arc against the interior wall of the fiber tube to enhance the generation of deionizing gases. The resistor element is soldered to the arc intercepting member and the conductor cap with solders having different melting points whereby the cap may be blown off the resistor to lengthen the distance between conductor elements.

Abstract: ABSTRACT        The specification describes composite metallic structures and more particularly inflated structural articles and methods of making such articles.  Sheets of malleable metal, either of the same or different metals, are solid-phase bonded one to the other in a conventional manner.  Prior to bonding a pattern of stop-off material which includes thermally decomposable material is applied to one or more interfacial surfaces to inhibit bonding of the metal sheets contiguous with the pattern.  The composite is then sintered to improve the metallurgical bond and then formed, as by cutting, stamping, bending, drawing, and the like into a selected configuration which can range from a generally planar element to a complex shaped element which includes com-pound reentrant surfaces.  Finally, the formed composite is raised above a predetermined temperature to decompose the stop-off material thereby generating a gas which inflates the composite along the areas defined by the pattern.

Abstract: ABSTRACT OF THE DISCLOSURE:         A first piston having a passageway for hydraulic fluid and a second piston slide within a cylindrical body of a jack for crown or disk brakes.  An extension of the first piston slides within a guide and actuates a movable pusher.  A closure seal closes the passageway when the first piston touches the second piston.  The sum of the axial fric-tion forces of the first piston on the cylindrical body and of the extension on its guide is less than the sum of the axial friction forces of the second piston on the cylindrical body and on the extension.  The displacement of the second piston takes up the wear of the brake linings while the dis-placement of the first piston effects the clamping of the brake linings on the crown or disk.
