Abstract: A method of forming an integral rivet in a sheet metal panel by successively coining portions circumscribing a central portion thereof so that the end panel stock is not stretched and a long shanked rivet is produced. The rivet has a relatively thin wall shank and a relatively thick crown which provides sufficient metal for stacking into a rivet head having a wide formable flange.

Abstract: A method of minimizing scrap loss in making a drawn container in a multi-die set cupping or end shell press which includes monitoring the sheet for defects before entering the press. The monitor is adapted to detect a defect, send a signal to a control when such defect is detected, and the control thereafter interrupts the operation of the punch of at least the die set in line with the defect when the portion of the sheet having the defect therein enters the die set and suspends such operation until the defect passes through the die set.

Abstract: A method and apparatus for measuring the sidewall tension in a workpiece being drawn through a draw die and/or ironing die. A punch is provided which is adapted to measure and continuously monitor the axial load on the punch nose and the total axial load on the punch, the distribution of such loads around the periphery of the punch, and bending of the punch near the base and nose due to lateral and nonuniform forces acting on the punch as the workpiece is forced through a die or dies. Determination of the forces, their distribution, and punch bending enables accurately determining the tensile stress at any portion of the sidewall.

Abstract: A blankholder having a central opening for applying pressure against the flange of a blank being drawn through a die in a draw press. The blankholder is divided into individual segments defined by its inner and outer peripheries, at least one continuous divisional line intermediate the inner and outer peripheries, and radii extending outwardly from the central axis. Each individual segment is provided with a different power source so that each segment can provide a force to the blank flange independent of the force being applied by any other segment.

Abstract: A value for controlling the flow of molten metal which includes a tubular conduit through which the metal flows and apparatus for applying a force against the exterior of the conduit to vary the size of the cross-sectional area of the opening through the conduit and thereby control the volume of metal flowing through the conduit.

Abstract: A system for attaching a bridge deck panel to a bridge structure which allows the panel to expand in lengthwise and sidewise directions independent of a bridge deck support structure. Brackets attached to members of a bridge deck support structure have undercuts on opposing ends which accommodate flanges on the bridge deck panel. Portions of the bracket overlying the undercut and flange prevent the deck panel from being separated from the deck support structure, but do not prevent the deck panel from lengthwise movement independent of the bridge structure due to temperature changes. To enable the panel to move in a sidewise direction, a space is provided between the outermost edge of the deck panel flange and the length of the undercut.

Abstract: Apparatus for casting metal which includes a mold having a central opening with a member attached to the top of the mold in concentric alignment therewith. Also included are at least three elements attached to the mold around the periphery of the member, which elements are selectively movable to be in or out of contact with the member, and when in contact, position the member in concentric alignment with the mold.

Abstract: A method of forming a drawn and redrawn container body which includes forming an inwardly projecting annular bead in the end wall of a drawn cup to be redrawn in order to prevent wrinkling in the end wall when it is subsequently formed into a pressure-resistant profile.

Abstract: A closure for closing the open end of a container having contents therein which dissociate a gas therefrom. The closure is adapted to provide an opening for access to the contents. The opening is adapted for a snap assembly with a plastic cap to effect a substantially gas-tight seal of the opening under high pressures to enable resealing of the container after dispensing a portion of the contents.

Abstract: A method of forming an integral rivet in a sheet metal panel by successively coining portions circumscribing a central portion thereof so that the end panel stock is not stretched and a long shanked rivet is produced. The rivet has a relatively thin wall shank and a relatively thick crown which provides sufficient metal for staking into a rivet head having a wide formable flange.

Abstract: A ventilator for attachment to a building soffit which is opened or closed automatically in response to a critical wind velocity. The ventilator includes a damper hingeably attached thereto which is acted upon by a wind of a predetermined velocity to cover the ventilator opening into the building and thereby prevent the introduction of wind-blown snow, rain or other particulate matter into the building.

Abstract: Apparatus for automatically straightening portions of a rod assembly having stubs extending outwardly from a yoke connected to the end of a rod and which is used in the electrolytic production of metals. A bent portion of the rod portion of the assembly is straightened by opposing anvils adapted for movement toward one another. As the anvils are closed together, a bent rod portion between them is straightened. The stubs which become toed-in during use are straightened by a stub straightening portion of the apparatus which is inserted between the stubs and actuated against the stubs with sufficient force to remove the toe-in. The apparatus is adapted to perform the straightening automatically on bent rod assemblies which are transported through the apparatus.

Abstract: A mechanism for rotating a hollow coil of wound material about its longitudinal axis, the mechanism comprising one or more rollers affixed to a cantilevered support with the mechanism adapted for a telescope fit into the hollow interior of the coil. The rollers are capable of being rotated about their axes and are positioned and attached to the support so as to contact the interior surface of the coil with their axes parallel to the longitudinal axis of the coil whereby the coil may be rotated to wind or unwind material on or off of the coil.

Abstract: A closure for closing the open end of a container having contents therein which dissociate a gas therefrom. The closure is adapted to provide an opening for access to the contents. The opening is adapted for a snap assembly with a plastic cap to effect a substantially gas-tight seal of the opening under high pressures to enable resealing of the container after dispensing a portion of the contents.

Abstract: A gauge having a substantially circular band capable of being deformed out-of-round from the application of a predetermined force and having a specified inner circumferential length to be compared with the length of a circumference around an object. The gauge further includes a support body adapted to connect with the band so as not to enable positioning the band in coaxial alignment with the object circumference and allow the band to flex and deform in circumscribing the circumference when the band is moved axially to accomplish such circumscribing.

Abstract: A preferably aluminum blind setting rivet including a detachable drill tip, preferably of steel, for self-drilling, the drill tip being attached to the rivet mandrel for drilling a hole to receive the rivet and being subsequently ejected from the mandrel during rivet setting.

Abstract: A container capping method and system for applying mechanical lock type tamper-evident closures to containers wherein the closures are heated prior to closure application to temporarily increase the flexibility thereof in a manner that tamper-indicating portions of the closures more readily withstand the closure application process without incurring visible damage or otherwise degrading the tamper-indicating function.
