Abstract: Seen against the direction of casting, the narrow width dimension of a mold is widened through appropriate surface contour, at least in the mold center, to facilitate charging of the mold whereby the lower portions of the longitudinal walls of the mold are essentially parallely curved while in the upper portion at least one of the walls tangentially merges into the pour-in portion of the mold.

Abstract: A metal, e.g. in the form of a shaped article, is made by atomizing a stream of molten metal and directing the atomized stream at a collecting surface to form a deposit of the metal. Fine, solid particulate material of different composition from the metal, e.g., nonmetallic particles, and of mean particle size less than 20 micrometers, preferably less than 10 micrometers, is applied to the stream or spray so that it becomes incorporated into the deposit. The particulate material is applied by generating a fluidized bed thereof and feeding it from the bed into the stream or spray. Uniform dispersion of material such as SiC at a high volume percentage (e.g. greater than 15%) may be achieved.

Abstract: The present invention provides a hinge construction of two mounting plates and a substantially U-shaped center link which connects the axes of pivot of the two plates. The link and plates contain stop mechanisms which determine their respective limits of pivot. In addition, the hinge contains a means for restraining the rotation of only one of the mounting plates around its corresponding link arm to insure a pattern of motion that is always consistent, and allows for the hinge to be mounted with a very narrow gap between the members being joined. The hinge of the present invention can be variably constructed to conform to a number of alternative uses.

Abstract: A brazing process is disclosed for joining two or more metal parts. The metal parts are brazed by interposing between the parts to be joined a brazing paste composed of a homogeneous microcrystalline rapidly solidified alloy powder having a composition consisting essentially of about 15 to 40 weight percent copper, 0 to 32 weight percent zinc, 0 to 24 weight percent cadmium, 0 to 3 weight percent nickel and 0 to 10 weight percent tin, the balance being silver and incidental impurities, and a phase structure such that the largest dimension of any precipitated phase ranges from about 0.01 to 0.1 micrometer, heating the powder to melt the powder, and thereafter cooling the parts to produce a brazed product. The brazing process can be carried out at lower temperatures as compared to prior art processes employing conventional BAg-alloy powders.

In order to create a simple, operationally safe, low maintenance dummy bar the flexible sheet includes recesses corresponding to the projection of the free projections of the contact elements.

Abstract: A soldering method is disclosed as adapted for attaching semiconductor devices such as transistors to their lead mounts. A layer of a solder paste, premixed with rosin flux, is first printed or otherwise formed on each of a series of interconnected semiconductor mounts which may be in the form of a sheet metal punching. The semiconductor devices are placed on the respective solder layers. Then the solder layers are heated to a prescribed temperature higher than both the melting point of the solder and a flux activation temperature at which the flux starts bubbling within the solder. For thus heating the solder layers, the series of semiconductor mounts with the semiconductor devices placed thereon via the solder layers may be fed longitudinally over a suitably heated surface.

Abstract: An ergonomic handle for a kitchen article is provided permitting three distinct holding positions.

The handle is formed of two successive non aligned sections.

Abstract: A snag-proof safety fishing lure includes a J-shaped hook having a barb at a curved end and an eyelet at the other end. A shield is pivotally connected to a shank of the hook below the eyelet to cover the lure when it is not submerged. When the hook sinks, submersion of the shield is limited to effectively lift the shield from the sinking barb. When the lure is lifted from the water, the weight of the shield causes it to be lowered onto the barb, effectively covering it to prevent snagging.

Abstract: A T-shaped animal trap having entry ports and sliding doors at opposite ends of its head portion and a platform resting on a dowel in its leg portion. A magnet is on each end of the dowel outside of the trap which can magnetically hold to each magnet a flexible metal wire when the entry ports are open, which wire extends into the head portion and is attached to one sliding door. When the platform is moved over the dowel, the dowel partially rotates and the wires are released from the magnets, thereby permitting the sliding doors to close the entry ports. Atlernatively, the animal trap may be tunned shaped with entry ports and sliding doors at opposite ends and a platform resting on a dowel near the middle of the tunnel.

Abstract: A quick glide lure has in a vertical longitudinal cross section a shape which corresponds to the shape of half of a falling water drop with a front downwardly convex portion and a rear downwardly concave portion of a lower edge.

Abstract: A ball bonding method and apparatus is disclosed including gold wire bonding. The steps include positioning and lowering a bond capillary (10) with a bond wire (11) including a flame-scarfed bond wire ball (12) downwardly onto a first bonding pad (17). The bond wire ball (12) is welded by heating and applying a bonding pressure or ultrasonic, or both. The bond capillary (10) is raised and moved to form a loop (21), followed by the step of welding the bond wire (11) to a second bonding pad (16) using heating and applying pressure, ultrasonic or both. The bond capillary (10) is raised to a tail-length position (29) and the bond wire (11) is broken by a vertical pulling force created by closing a clamp (13) onto the wire and raising the clamp (13) engaging the bond wire (11). The end of the free bond wire is flame-scarfed to form a bond wire ball (12).

Abstract: An improved means and method for bonding closely spaced parallel wires for applications in electronic devices, circuits and assemblies is described herein. A wire guiding means is provided located between a bonding wedge and a releasable wire clamp of a conventional wire bonder. The wire guide means has a slot which constrains motion of the wire during bonding to a plane perpendicular to the plane of the bonding pad and substantially prevents motion of the wire transverse to this perpendicular plane. This prevents the bonding from introducing minute variations in the transverse displacement of the wires, such variations being absorbed by small variations in the wire loop height.

Abstract: A removable and replaceable weed guard may be added to a fish hook to prevent the hook from becoming entangled with weeds. The weed guard may be made of wire or other spring material and a set of weed guards may be used to calibrate a hook so that the depth and speed of motion of a lure to which the hook is attached may be controlled. The weed guard of the invention is a bait saver, since it prevents live bait from accidentally falling off the hook.A connecting loop for securing to a lure and a figure-eight connector for attaching a fish hook to a lure are also described. A hand tool is useful for attaching the connector.

Abstract: A two-piece door handle for refrigerators and freezers is mounted on the edge of the doors by two fasteners. The handle includes a plastic molded part and a metal stamping. The plastic molded part provides a recess in which the entire metal stamping is positioned. Shoulders surrounding the recess engage all of the edges of the metal stamping, obscuring them from view and preventing user contact with such edges. The recessing of the metal stamping eliminates the need to provide a finish coating on the edges of the metal stamping. The molded plastic part provides a mounting flange portion positioned between a mounting flange portion on the metal stamping and the associated door. Therefore, metal-to-metal contact is prevented. The two pieces of the handle are easily snapped together as an assembly and are easily installed on the associated door.
