Abstract: A method and apparatus for joining an end of a flexible membrane to a rigid backing. A sleeve is used which plants a portion of the membrane and a resilient member in a seat, preformed along an edge of the backing. A punch associated with the sleeve then forms the edge over the resilient member to capture the member and membrane in the seat and at the same time severs any excess portion of membrane along the edge. In one embodiment the membrane is a tube having an end joined to an annular backing about the opening in the backing.

Abstract: A method of attaching a metal shaft (10) to a ceramic shaft (12) having a first diameter (d.sub.1) is characterized by the following steps. A shaft portion (16) is formed on the ceramic shaft with a second diameter (d.sub.2) less than the first diameter. The shaft portion extends from a free end (18) thereof along a portion of the length of the ceramic shaft to a terminal end (20) thereof. A circular shaped metal lock nut (22) is placed on the shaft portion in an encircling relationship therewith. This lock nut has threads (24) on an outer facing surface thereof and a back end (26) which contacts the terminal end of the shaft portion. A circular shaped expansion sleeve (28) is placed on the shaft portion in an encircling relationship therewith, the expansion sleeve extending from the metal lock nut to the free end of the shaft portion.

Abstract: For the attachment of a flare composition sleeve in a bore at the tail of a projectile body it was heretofore necessary to maintain very exact fabrication tolerances in order to provide a reliable sealing action against the propellant gases. To avoid this drawback the invention contemplates, in a first method step, pressing the flare composition sleeve, with the aid of a pressing plug or pin, into the bore at the tail or rear portion of the projectile body and, during a second method step, a ring-shaped edge of the flare composition sleeve is enlarged by means of an elastically deformable, such as a plastic or rubber plug until the ring-shaped edge bears against a ring-shaped groove of the bore wall of the projectile body. The flare composition sleeve possesses at the aforementioned end confronting the projectile body a smaller or at most the same wall thickness as at the remaining region.

Abstract: A unique building wiring system is disclosed. When the building framework is completed and the studs and ceiling joists are exposed, the workman places a mark on the floor directly beneath where an electrical outlet box or the like is to be placed. The workman then drills a vertical hole in the horizontal top plate and directly above the floor mark. A visual locator tool is positioned in the hole so that it is hangingly supported by the top plate. The wall and ceiling panels may then be installed by other workmen. Subsequently, the electrician enters the closed crawlspace where he can easily find the locator by visual observation. He attaches his electrical wiring to the locator and releases the latter so that it drops down from the hole by gravity, carrying the wiring with it in a generally vertical line.

Abstract: The disclosure concerns a smooth continuous steel trough, free of longitudinal weld joints except for a flanged frame attached to its open top for supporting a cover grating. The apparatus for performing these steps comprises a conveyor table for moving and clamping a parallel edged sheet of steel while it is cut, such as by a torch, to predetermined length sides, and angled ends corresponding to the flow pitch for the resulting trough. The resulting isosceles trapezoidal section is then conveyed and aligned under an oscillatable convex mandrel or roller having a longitudinal clamping rib axially along its periphery for clamping the trapezoidal sheet near its center at the bottom of what is to be one of the equal side walls of the resulting trough. The conveyor and/or support for the sheet at the mandrel is vertically adjustable to compensate for different size mandrels and thicknesses of the sheets.

Abstract: A method and apparatus for feeding sliders to a slider pocket are disclosed. Sliders taken from the pocket are assembled on the fastening element sections of an uncut fastener chain which is moved and stopped intermittently to allow the assembly of the sliders wherein sliders longitudinally aligned and delivered by a slider chute are fed into a slider holder one at at time. The slider holder carrying a slider received from the chute is transferred to a slider assembling station from a direction at right angles to the direction of fastener chain transfer, and the slider is loaded at the slider assembling station into the slider pocket which is provided at the upper end of a slider pocket block raised from the direction at right angles to both the fastener chain transfer direction and slider transfer direction, and the slider holder is returned to the exit of the slider chute. These steps are repeated in synchronism with the stopping of movement of the uncut fastener chain.
