Abstract: A corrosion resistant insert of the present invention is used for fitting at an opening in a metallic liquid tank. The insert has an open end, a radially outwardly extending lip at the open end, a closed end and an axially extending side wall spacing the open end and closed ends from one another. The closed end has a displaceable portion secured to the insert in a preweakened manner which facilitates opening in one direction while resisting opening in the other direction. The use of the insert in the tank enables lining and then pressure testing of the tank ready for fittings after which the closed end of the insert is opened to allow liquid flow through the tank when the tank is in use.

Abstract: The present invention method is carried out with a programmable automatic wire bonder having a linear drive motor. The wire bonder is programmed to bond loose lead frame leads at a second bond position in a novel manner. The lead frame lead to be bonded at second bond is clamped in a work holder that leaves the ends of the lead frame leads loose above the bonding mandrel of the work holder but restrained to a predetermined floating zone that is established within a predetermined distance above the bonding mandrel. The bondig tool is programmed to engage the loose lead frame lead at second bond at a predetermined velocity which permits the bonding tool to simultaneously exert an impact force on the wire to be bonded and to clamp the loose lead frame lead.

Abstract: Crushing or other damage to the hackle of an artificial fishing fly during transport of a fly rod is prevented by a device which includes a base member and a clip engageable by the hook of the fishing fly. A first facility mounts the base member in close proximity to the rod near its handle. A second facility mounts the clip to the base member for selective movement between two positions. In the first position, the clip is retracted and physically proximate to the base member and the rod so that the base member and the clip present a low profile and do not interfere with the line during fly casting. In the second position, the clip protrudes and extends away from the base member and the rod by a distance sufficient to hold the hackle of a fly away from and out of contact with the base member and the rod when the hook engages the clip thereby preventing crushing of the hackle during transport of the rod.

Abstract: In a method for connection of railway point components (1) such as, for example, frogs consisting of austenitic cast hard manganese steel, or manganese steel rails, to rails (2) made from carbon steel, with the utilization of an intermediate piece (3) made from low-carbon austenitic steel, in which method the intermediate piece (3) is first-of-all welded to the standard rail or connecting rail (2), following which, after cutting off the intermediate piece (3) to a length of less than 25 millimeters, in a second welding operation, the intermediate piece (3) is welded to the component (1) consisting of cast hard manganese steel or to the manganese steel rail (1), an intermediate piece (3) consisting of a low-carbon, austenitic, steel, in particular a chromium-nickel-steel, stabilized with niobium and/or titanium, is utilized and, following the first welding operation, a heat treatment, in particular a diffusion-solution at a temperature between 350.degree. C. and 1000.degree. C., is carried out.

The apparatus is preferably constructed of light weight and durable tubular and other molded plastic components.

Abstract: The activator is cut and shaped from sheet plastic and installed on the leader just in front of the lure attached to the leader. Motion of the lure and activator through water causes the activator to oscillate angularly, generating alternating lateral forces on the leader and thereby activating the lure. In a preferred embodiment the planform of the activator is circular with a hole at its center and the activator is creased radially from the hole to its perimeter so that the portions of the activator adjoining the crease are at a shallow angle to each other. Creasing, as different from bending or forming, stretches the material at the open side of the angle at the crease beyond its elastic limit and allows it to take a set. The stretched material is under compression when the part is finished, the compression holding the adjoining portions at an angle. This technique virtually eliminates the tendency of the plastic to resume its preformed shape and allows manual adjustment of the angle.

Abstract: The apparatus is mounted on a deck of a boat and includes an elongated track with an inboard end and outbroad end disposed to at least the waterline for capturing a line having a float on one end and a subsea trap on the other end. A trolley is movably mounted on the track and a funnel-like guide structure is connected to the outboard end to direct the float and line, as the boat moves forwardly, to a capturing hook mounted to the trolley. Upon movement of the trolley inboard the float and line are drawn to permit a hydroslave pulley to pull the trap to the boat above the waterline thereby harvesting the catch therefrom and rebaiting same prior to returning the trap to the sea. A novel method of retrieving the subsea traps is also set forth herein.

Abstract: A spear structure is defined by an elongate truncated conical body formed with a forward section and rear section intercommunicated by a frangible hollow sleeve arranged for separating the forward section relative to the rear section upon impact. A spring member directed through the sleeve and secured at its upper and lower distal ends to the forward and rear sections secures the forward and rear sections together upon such separation to preserve the rear section for reuse.

Abstract: The present invention relates to a new, useful and humane foot-snare trap for trapping of fur-bearing animals. More particularly the invention relates to a unique snare trap design which utilizes a vertically oriented coiled spring which, when triggered, releases vertically to cause constriction of the snare about the leg of the animal in the trap. The vertical arrangement of the coiled spring leads to an upward release of the snare which provides a means to minimize the loss of snared animals while also minimizing the discomfort or injury to the animal and damage to the animal pelt by the recoil spring action.

Abstract: A bait threading device receives a piece of bait on a shank longitudinally mounted to a handle. The shank terminates in a distal tip, preferably canted, that receives the barb of a fish hook, and the handle has an arm member that projects outwardly therefrom and includes structure, such as a notch, to receive a portion of fishing line connected to the hook so that the hook is securely retained with the line held tautly. A piece of bait may be advanced off of the shank and onto the hook and, if necessary, the fishing line. By canting the shank end and by selecting the shank and arm lengths, the end of the shank may be aligned with the barb portion of the hook and the line may be aligned with the shaft of the hook. To this end, the shank may be adjustably mounted to the handle. Either of the shank or the arm may be detachable, and the handle provides a storage compartment for one or both.

Abstract: A solder bump stretch device is disclosed for use in mounting an electronic component to a substrate by a plurality of solder bump interconnections that are produced by reflowing preformed solder bumps carried on the component. the device is fastened to the component, which is in turn assembled with the substrate so that the bumps rest upon the substrate in preparation for solder reflow operations. The device comprises a flexible web that overlies the component outer face and is connected to legs that depend about the component. Prior to solder reflow, the web is held by an expendable spacer in a biased position wherein the legs are raised apart from the substrate. During heating to melt the solder bumps, the spacer is expended, releasing the web, whereupon the legs engage the substrte to lift the component relative to the substrate and thereby stretch the molten solder to form elongated interconnections preferably having hourglass configurations.
