Abstract: The invention concerns a punch device that includes an actuating member of flat proportions, a penetrating tool with a sharp tip carried by the actuating member, a compressible spacer attached to the surface of the actuating member alongside the penetrating tool and mounting means for mounting the punch device on a glass sheet with the tip of the penetrating tool directed towards the glass sheet. The arrangement is such that a force of sufficient magnitude applied to the actuating member in an axial direction towards the glass sheet compresses the spacer and drives the tip of the penetrating tool into contact with the glass sheet thereby to break the glass sheet. In one application the punch device can be used to break an emergency exit window in a bus.

Abstract: A liquid-cooled armature bar end fitting-to-strand brazed connection. The end fitting is comprised of a main body and a cover, and defines a cavity, a bottom wall of which is defined in part by the cover. An armature winding bar strand package including solid strands and hollow strands arranged in a tiered array extends into the end fitting so that at least the free ends of the hollow strands extend beyond the bottom wall, into the cavity. The side wall of the cavity is spaced from the hollow strands. A braze alloy joins the strands to each other and to the end fitting. The braze alloy forms an isolation layer over the free ends of the solid strands and over the said bottom wall of the cavity to a depth above a horizontal junction between the main body and the cover.
