Abstract: A mechanism for straightening bent terminals on an integrated circuit package comprises a base having a pair of spaced apart arms pivotally coupled thereto. Rollers attach to the arms to support and move a plate when the arms are pivoted. The plate has a first set of holes which are tapered to accept bent terminals and to straighten them when they are forced into the taper. A plurality of pins extend from the base between the arms and stop parallel to the plate. The plate has a second set of holes through which the pins move when the arms are pivoted. A plurality of intermeshed gears couple to the base and the arms to pivot the arms in synchronization and move the plate perpendicular to the pins which push the integrated circuit package straight out of the first set of holes.

Abstract: A method of tying a wire tie about two crossed reinforcing steel sections and a portable machine, used for automatically installing wire ties on the steel reinforcing bars used in concrete building structures. The machine includes a fixed upper stop piece, two lower jaws, a wire feeding device, a wire guide which includes a spiraling channel divided into several complementary sections cut from a number of independent pieces, a hinged pair of tongs, a rotating pair of tongs and a cutting edge. The wire tie holding together two reinforcing steel sections has the general shape of a "figure 8" loop which is bent perpendicularly to its plane, both loops of the "figure 8" face each other, the locking twist being located at the center crossing of the "figure 8". This machine may be readily adapted to various dimensions of steel cross-sections.

Portions of a short handle member and a pivoted clamping member have cooperating jaws to receive a battery terminal between them. The handle member carries clamping means adapted to engage the clamping member to force the jaws together sufficiently to swage a terminal onto a cable end inserted into a bore in the terminal.

Abstract: A method and apparatus for manufacturing wire link bands, for example for use in paper making machines, are disclosed. Several wire links or helices are arranged parallel to each other, adjacent helices having opposite pitch. The helices are simultaneously fed through a closure slot while under tension. The closure slot is so shaped as to cause each turn of each helix to be engaged between two adjacent turns of an adjacent helix, thereby to form a wire link band. The closure slot may be held stationery while the wire links are pulled therethrough, or the wire links may be held stationary under tension while the closure slot is moved along their length. A plurality of closure slots may be used to form several wire link bands in parallel, and at least one additional closure slot may then be used to combine the wire link bands into a larger wire link band or sieve. Connecting rods may also be inserted into the wire link bands and may be heat fixed before insertion.

It also features, in cooperation with and in opposed relation to the punch, an assembly providing a rotary bending tool comprising a notched rotor contained for rotation in and with respect to a saddle, which is contained, in turn, by and for movement relative to a base member in a construction and arrangement wherein the relative position of the saddle and the rotor may be precisely and quickly gaged by a segment of the sheet material to be worked between the punch and the rotor of the opposed rotary bending tool.

Abstract: Packaging of certain products like cheese is usually done in a vacuum without the presence of heat. Heretofore, a first vacuum was necessary to knit the curds together and to compact the cheese. A second vacuum was then employed to remove air which returned to the package. The present method eliminates the need for the second vacuum. A heat sealable package, containing cheese, and having a tortuous vent passage is subjected to a vacuum. As a full vacuum is achieved, air within the chamber and the package is exhausted. When the chamber is returned to atmospheric pressure, the tortuous seal collapses to form a temporary seal. At the same time, the plastic bag collapses around the cheese which causes the curds to knit together, and compact the cheese. While still in the sealed condition, a permanent heat seal is made across the tortuous vent passage.

Abstract: The invention relates to a device for producing and removing shaped wire material pieces wherein said device comprises a frame which is supplied with bars, said bars being supplied to measuring, cutting and shaping means mounted on the frame, which latter rests on the ground by way of supporting legs defining a space under the frame to allow the passage of a moving tray on which the pieces are unloaded for removal after shaping.

Abstract: A holder is provided to retain the closure flaps of a carton or container in an open configuration. The holder has three projecting prongs extending in parallel, spaced-apart relation from a spine portion. In using such holder, the central prong is extended downwardly at the inside of a corner of the carton while the two outer prongs extend downwardly at the outside of the carton adjacent the corner. When the holder is thus used, closure flaps of the carton, which are hinged to respective sides of the carton at the top, are held in downwardly folded open positions by the outer prongs of the holder.

Abstract: A nitrogen die cylinder is disclosed having an upright post threaded at its lower end into the wall of a manifold containing nitrogen at high pressure. The post has a central vertical passageway extending therethrough and communicating with the manifold. A cylindrical sleeve having a top wall is telescoped over the post. A seal at the upper end of the post engages the bore of the sleeve to form a chamber between the seal and the top wall of the sleeve which, when pressurized, urges the sleeve upwardly on the post. The top wall of the post has a noncircular socket therein which is accessible through an opening in the top wall of the sleeve which is normally closed and sealed by means of a threaded plug.

Abstract: A method of transporting uncured RTV silicone rubber is the subject of this invention. The silicone rubber is placed in a container and a quantity of argon gas is then added to the container before it is sealed to prevent escape of the gas.

Abstract: A machine for use in shaping the leads of electronic components has a component transporter which comprises a pair of discs each having a resiliently flexible outer peripheral portion in which a plurality of lead receiving notches are formed. Edge separation slots subdivide the peripheral edge portion into a plurality of independently flexible segments. Magnets are arranged to deflect successive segments laterally away from one another during passage through the loading station to widen the gap between the segments to receive the body of a component therebetween and thereafter permit the successive segments to move toward one another to clamp in the body of a component therebetween. A transfer wheel has a peripheral edge formed with a plurality of component recesses. The transfer wheel is mounted to rotate with its peripheral edge overlapping a length of the outer peripheral portion of the discs during passage through the loading station.

Abstract: A power driven wire twister is suitable for twisting relatively heavy multi-strand wires. The strands are twisted by means of a chain and sprocket drive. The wire twister housing and output sprocket are suitably slotted to allow placement of the wire at the axis of rotation of the twisting sprocket. A tooth carried by the output sprocket separates the strands of the wire into two approximately equal groups prior to twisting. A large angle of contact between the chain and slotted output sprocket insures that a sufficient number of sprocket teeth are always in mesh with the chain for heavy duty continuous operation.

Abstract: The watt loss of a grain-oriented electromagnetic steel sheet can be reduced by known methods in which serrations or scratches are locally formed on the steel sheet or a small ball or disc is rolled or rotated over the steel sheet. The known methods are disadvantageous in that the rate of production is low and in that the steel sheet has a marked unevenness.In the present invention, particles, e.g., steel shots, are projected onto substantially linear selected portions of a grain-oriented electromagnetic steel sheet, thereby producing strain in spot-formed regions. An apparatus according to the present invention comprises an endless conveyor and a means for projecting particles. Slits are formed in the endless conveyor, and particles are projected through these slits onto the substantially linear selected portions.
