Abstract: An assembly system for assembling microcomponents of semi-conductor or other electronic devices includes on a unitary machine frame the tooling for precision excising tape mounted microcomponents, precision forming their electrical leads, placement of the components in correct registration with conductors on a pre-positioned substrate, and bonding the formed leads to the conductors. Bonding is conducted by clamping the leads to the conductors at the bond site, moving a heated anvil into contact with a heat conductive path to the bond site and withdrawing the heated anvil while maintaining the clamping.

Abstract: A spindle for an axle is capable of supporting a vehicle wheel which is rotatably mounted thereon. The method for forming such a spindle includes providing a hollow tubular blank having a generally uniform external diameter and wall thickness and forming the blank to generally reduce its diameter to thereby provide a pair of axially separated wheel bearing mounting regions for supporting the vehicle wheel. A portion of the blank inwardly of the inner bearing region is provided a frusto-conical outer surface. A collar having an inner surface to match the taper of the frusto-conical surface is installed thereon for providing an axial stop for the adjacent bearing. Several alternative methods are provided for securing the collar thereon.

The apparatus includes a fixture in which at least one and preferably a plurality of laterally oriented grooves are disposed in the upper face of a heat resistant fixture which in turn is adapted to move longitudinally with respect to a frame which supports the fixture. In addition to the laterally oriented grooves, at least one and preferably a pair of longitudinally oriented grooves are disposed in the face of the fixture in intersecting relation to said lateral grooves.

Abstract: A wire vibration damping device for use in coil winding machines of the wind and shed type. The device comprises a guide rail which partially or completely encircles the coil form and is connected to the structure which supports the coil form by means of a plurality of downwardly depending guide posts. The guide rail is supported from above the winding plane and includes a downwardly facing lower edge which is located slightly above the winding plane yet sufficiently close to it that it deflects excursions of the wire above the winding plane as it is fed from the flyer thereby damping oscillations of the wire which would otherwise cause improper shedding off the coil form. The support posts for the guide rail are clamped within a bracket mounted to the lower portion of the support structure for the coil form and are vertically adjustable relative thereto so that the position of the guide rail can be fine tuned to ensure optimum damping of the wire oscillations.

Abstract: A chip carrier (5) having a plurality of first ends (21--21) is aligned with and bonded to mating lands (34--34) on a PCB substrate (31) by positioning the carrier in a recess of a nozzle (66) on the tool and directing individual streams of hot gas horizontally onto the terminals and lands to cause previously deposited solder thereon to reflow to bond the articles together. Alternatively, articles bonded with reflowable material may be de-bonded in a like manner.

Abstract: In order to provide a method of producing magnetron anode at a good mass-produceability, according to the invention, so-called straight type steel cylinder blank the inner peripheral surface of which is not tapered is used and, at the same time, the step of quench-hardening of the steel cylinder blank is omitted. After fitting a copper block to the inside of the straight type steel cylinder blank which has not been quenched, both members are compacted to each other. Then, a press working is effected on the copper blank such that the steel cylinder blank and a back-up punch are forced to move relatively to each other, when a press-working shaping punch is forced into the copper block, thereby to form a copper anode. In order to avoid the bursting of the steel cylinder blank, the press work on the copper block is effected at a temperature of 200.degree. to 650.degree. C.

Abstract: An apparatus for joining and cladding pipe sections has a cradle which holds two cylindrical pipe sections with their ends abutting axially and their axes coaxially horizontally aligned. A carriage is displaceable axially adjacent the cradle and carries a primary welding tool which can weld the ends of the pipe sections together as they are rotated in the cradle. Metal strip can be pulled of a supply of strip on the carriage, bent into a U-section, arced, and helically applied to the pipe sections as they rotate. Meanwhile a second welding tool on the carriage welds the arced U-section strip to the pipe sections as they rotate to form a helical passage therealong.

The apparatus incorporates successively arranged entry guide rollers with an inductor in-between, bending rollers, a cooler and exit guide rollers. An additional inductor with cooler is provided between the exit guide rollers to enable surface-hardening of spring leaves. The cooler, additional inductor with cooler and the exit guide rollers are arranged along a circular arc whose radius is that of a specified radius of curvature of the spring leaf.

Abstract: A method of and apparatus for continuously hot rolling steel slabs. Separate pieces of steel slabs are continuously fed from a slab yard and delivered to a carriage which is adapted to move reciprocatingly along the line of path of the steel slab pieces. The carriage carries a welder which can move transversely of the path of the slab pieces, and also clamp devices for clamping preceding and succeeding slabs to fix them to the carriage, as means for keeping the preceding and succeeding slab pieces in abutting condition. As a steel strip including a plurality of slab pieces welded together is moved at a predetermined rolling speed into a rolling mill, the carriage moves substantially at the same speed to keep the succeeding slab in abutment with the trailing end of the last slab piece of the steel strip, to permit the welder to weld these slab pieces at their abutting end. This welding is performed only over a part of the cross-sectional area of these slab pieces.

Abstract: Ferrous parts are bonded together in a copper brazing furnace under suitable temperatures and a furnace atmosphere which, in the absence of parts, is comprised of at least 90% nitrogen, up to 7% combined hydrogen and carbon monoxide with hydrogen being greater than 50% of the total of CO and H.sub.2 and having a dew point between approximately -40.degree. to +10.degree. C. In the preheat section of a continuous belt furnace or the like, the dew point may range between -20.degree. to +10.degree. C. while in the furnace hot zone, the dew point is maintained between approximately -40.degree. to -10.degree. C. A brazing paste which is preferably a combined copper and 25-75% copper oxide paste is utilized. With such furnace atmosphere and paste composition, clean part surfaces, which permit superior wetting by molten copper and thus acceptable copper flow and penetration into the joint being bonded, are obtainable.

The pin cam is remote from the torch and probe assembly and is electrically synchronized with it. Means are also disclosed to permit a single pin cam wheel to store horizontal and vertical deviation information and gap width information simultaneously.

Abstract: The following specification discloses a parts handling and storage system that can be directed toward the handling and storage of electronic components. The storage portion comprises a movable cabinet on wheels having a plurality of elongated tubular members or channels that receive components or parts along the length thereof. The tubular members or channels are driven on a linked basis parallel to each other by a gear movement and chain drive. In this manner, the channels themselves in their linked relationship form a chain of axially elongated links. Each respective channel or tubular member can be indexed at a given point for exposing the parts therein, so that they can be moved therealong into an adjacent track or channel or other handling means. The storage cabinet and tubular channel members when combined with an extended track can be associated at the end of the track with a second storage cabinet for receiving the parts after they have been processed from the first storage cabinet.
