Abstract: A fising jig using a chemiluminescent capsule. The jig includes an elongated, weighted fish shaped body having a longitudinal extending cavity for receiving and holding the chemiluminescent capsule therein. The cavity has a pair of light emitting openings in the opposite sidewalls of the body communicating with the cavity. A continuous bore extends longitudinally and fully through the body from the forward to the rearward end, and a resilient tubular line guide is disposed in the bore. The line guide is a resilient Teflon tube having a lengthwise bore with a low friction, nonchaffing interior wall surface. The line guide bore is sized to loosely receive a fishing line and allows the free sliding of the jig along the line and the free rotation of the jig about the line during usage. The line guide has a resilient forward end portion extending out of the body bore at the body forward end by a distance sufficient to provide a shock absorbing action as the jig wobbles on the line during usage.

Abstract: A tool for use in ultrasonically bonding a wire to a metal surface has a tip having a compound curved channel having a central concave surface and a peripheral non-convex surface along each edge of the central surface. The central surface has a cross-sectional shape similar to that of a portion of the wire's cross section. The total cross-sectional area of the channel should be at least 50% and less than 100% of the wire's cross-sectional area. In a preferred embodiment, the cross section of the central surface is an arc of a circle approximately centered on a line drawn between the outer edges of the peripheral surfaces of the channel. The preferred embodiment also has a beveled surface intersecting an end of the channel to provide a gradual transition for the wire shape from the bond to the undistorted wire.The tool when used to bond an appropriate wire by an ultrasonic bonding machine produces a wire whose outer shape in the bond area conforms to the shape of this tool's channel.

The hoops are normally in positions in which the net openings interset to form an enclosure for capturing of birds and other small animals. The distal edges of the hoops may be forced, through opposing arcs, from normal positions to set positions, in which the distal edges are displaced less than one hundred eighty degrees for engagement with a release assembly. The release assembly is remotely operable to release the hoops for self imposed return to the normal positions.

Abstract: A pistol-grip, elastic-operated insect swatter is disclosed which comprises a supporting hand gun member with a pistol hand grip and an elongated barrel extending outwardly therefrom. The outermost end of the barrel is downturned or, if straight, has a downwardly curved surface at the end. An elongated flat band of elastic material has one end secured to the downturned end portion of the barrel is substantially shorter than the length of the barrel. An insect-swatting pad has one side secured on the other end of the band of elastic material. A firing and retaining trigger, is positioned adjacent to the handle and is operable in one position, upon stretching of the band, to receive and secure the swatting pad. The firing and retaining mechanism, i.e. trigger, is operable upon movement to another position to release the pad for movement by the stretched band with a snapping movement to swat at an insect.

Abstract: A novel and improved monitoring and detecting circuit is provided for an automatic wedge wire bonder. The detecting circuit is initiated at the second wire bond while the bonding tool is pressing the bonding wire on the pad or electrode. If the fine wire is missing under the working face of the bonding tool, the sensing circuit initiates a signal which is detected by control means so as to initiate an interrupt signal stopping the operation of the wire bonder. Sensing of the presence or absence of a wire under the bonding wedge at a bond may take place at a first or a second wire bond. At the second wire bond, the novel sensing and detecting circuit is actuated to determine the amount of longation that takes place in the bonding wire between the bonding wedge and the wire clamps so as to correct the movement of the wire clamps when supplying a tail under the working face of the bonding tool and to ensure that a uniform tail length is supplied unaffected by the elongation of the bonding wire.

The trigger portion of the trigger structure is an injection molding product made of plastic so as to give an excellent touch feeling, whereby there is no fear that such trigger portion does some damages to the user's finger and hand even when such trigger portion hits the user in his finger and hand strongly at time when he performs his rapid hand changing operation in the fishing rod.

Abstract: A fishing lure is described which lure is constructed of a treated sheepskin material which treatment keeps the sheepskin soft and flexible when the lure is placed in water even though it has been previously used an allowed to dry. The lure is shaped according to the present invention in a way which is especially effective in catching fish. Further, a tubular sleeve is used in combination with the hook and the lure body to hold the lure body in the proper effective position, and a clasp is used for mounting the lure body to a weighted head secured to the hook.

Abstract: The present invention is directed to a novel device for reducing the friction which is generated when a trawl net is dragged along the ocean bottom. A trawl net, as it is being dragged in a forwardly direction, comes in contact with not only debris on the ocean floor but also with the substrate comprising the ocean floor, thus increasing the friction being applied to the net, which reduces the life of the net. The novel device contemplated herein is a device which is generally spherical in configuration, although somewhat elongated in one direction resembling a bobbin. The device is made of at least two parts which can be easily placed on the net webs or net lines, preferably at a rearwardly location with respect to the forward movement of the net. As the net is being pulled, the device, which is in contact with the ocean bottom, rolls, thereby reducing the contact between the net and the ocean bottom and also maintaining the net at a distance certain from the ocean bottom.

Abstract: An improved automatic wire feed system for supplying a fine wire to a capillary bonding tool or to a wedge bonding tool is provided. The wire feed system includes a novel wire feed slack loop device which is mounted on the wire bonder between the bonding tool and the source of fine wire. The novel wire feed slack loop device comprises a pair of sector plates which are closely spaced apart from each other to provide an air space therebetween for receiving the fine wire. Compressed air is supplied to the air space between the sector plates and is directed radially outward by a diffuser shim plate which forces the wire to form into a uniform circular shape in the air space. Sensor means are provided at the outer perimeter of the sector plates which sense the position of the fine wire and supplies a signal to control means which turns off the rotation of the drive motor.

Abstract: A hollow, elongated tubular member, constructed of flexible resilient material and including an inlet-outlet for admitting and discharging fluid under pressure, is adapted to be disposed in a hole in a layer of ice so that the top and bottom ends extend upwardly and downwardly above and below the layer of ice such that, when inflated, the top and bottom ends expand to seal the hole and to retain the hollow tubular member as an easily removable plug to displace water within the hole and thereby prevent reformation of the ice therein. The method of temporarily plugging a hole in a layer of ice includes the steps of providing an elongated, resilient inflatable tube, inserting the tub partially through the ice hole and inflating the tube to expand the top and bottom so as to retain the tube in the hole.
