Abstract: A method of improving a fishing lure by taking an existing fishing lure and adding a powdered metal such as lead or tungsten to the soft material during the re-production phase to add weight, wherein the amount of added weight enables the resulting improved fishing lure to sink to different depths at a faster sinking rate. The subject disclosure contemplates first-time production of fishing lures with added powdered weight as well as re-production, wherein a pre-existing lure of substantially only soft material is melted down, powdered weight is added to the more viscous, melted soft material, which is then allowed to reconstitute through cooling, thereby resulting in a heavier version of the pre-existing lure.

Abstract: A feed-forward amplification circuit, for producing compensated output signals, comprises an amplifier arranged to receive a plurality of input signals including a control signal, within a predetermined frequency range, and to produce a plurality of amplified signals including said control signal, within said predetermined frequency range, wherein said predetermined frequency range lies within the operational range of the amplifier. Phase shift means are arranged to receive said input signals and said amplified signals and to introduce a relative phase shift between said input signals and said amplified signals to produce an error signal. Combination means for combining said error signal with said amplified signals to produce said compensated output signal; and control means for controlling said phase shift means in dependence on the relative phase difference between the control signal in said input signals and the control signal in said amplified signals.
