Abstract: A fishing lure including a membrane extending from the lure body dimensioned to fill the gap between the lure and a fishing hook rigged on the lure.

Abstract: A bait securing means comprised of a helical wire coil including a means for securing one end of the helix to a fish hook eye by snap fit deformation of the wire. The dimension of the helix is calculated to allow the shank of a hook to pass coaxially through the coils and to permit a bait such as an artificial worm to be screwed onto the unsecured end of the helix so the helix will be completely enclosed within the end of the bait and a web of bait material greater than the diameter of the wire is present between the coils of the helix.

Abstract: A platen roll core member including an axle part, an external tube part coaxially disposed around the axle part and webs extending therebetween having a plurality of projections formed by at least one surface extending rectilinearly in the axial direction and integrally formed on either the outer surface of the axle part, on the inner surface of the external tube part or on both the outer surface of the axle part and the inner surface of the external tube part. Striking sounds generated as the platen roll core member is struck from outside make irregular reflections within a cavity of the core member due to the plurality of projections which results in quieter operation of the platen roll.

Abstract: A positioning system is provided in which command and feedback signals are processed to develop an analog error signal for application to a servo drive to position a controlled element. The command signals are in the form of pulses each of which corresponds to a certain incremental distance of movement. The feedback signals are developed from phase shifts of a low frequency resolver signal, such phase shifts being proportional to movement of the element. Such feedback signals are applied to a resolver digitizer circuit which develops a train of resolver pulses in response to the phase shift represented by each feedback signal. Each such resolver pulse corresponds to the same incremental distance of movement as a command pulse and both the resolver pulses and the command pulses are applied to a comparator and error signal circuit in which any cumulative error in either direction is stored as a digital number and is converted to an analog error signal of the proper polarity.

Abstract: A method and apparatus for producing fishing lures incorporating hook hangers which utilize a bore formed in the lure body as part of the connection mechanism. Injection molding techniques are utilized to fill cavity molds having removable inserts therein.

Abstract: A fishing system is presented wherein a fishing lure may be made to operate at predetermined optimum depths as a function of changes in the effective density of the fishing lure assembly which is accomplished by the selective use of hooks, having predetermined weights, attached to the lure by hook hangers which utilize a bore formed in the lower body as part of the connection mechanism.

Abstract: A connector for securing an object having a loop or eyelet affixed thereto is provided by an open loop of rigid, spring wire or similar material which is secured to a body so that one leg of the opened loop enters, and essentially traverses a bore within the body.

Abstract: Fly fishing apparatus including a double-ended special connector having horizontal and vertical eyes at each end between the fishing line and a leader connected to a fishing hook also having a horizontal and vertical eye whereby the cutting of lines and tieing of knots is eliminated. In modifications the upper end of the double-ended special connector is provided with a horizontal eye only for receiving the knob of a plastic fishing line resulting from the application of heat or for receiving the fishing line with a knot therein.
