1. A diving lip projecting from the front of a fishing lure having a longitudinal axis and a fishing line connecting loop, said diving lip comprising:
rear, intermediate and front sections, each of said sections having an upper surface;
the fishing line connecting loop being disposed between the rear and intermediate upper surfaces;
said rear upper surface being disposed at a downwardly inclined angle \u03b1 relative to a first plane, said first plane being approximately parallel to the longitudinal axis of the lure;
said intermediate upper surface being disposed at a downwardly inclined angle \u03b2 relative to a second plane, said second plane being approximately parallel to said longitudinal axis;
said angle \u03b2 being larger than angle \u03b1; and
the front section of the diving lip being disposed approximately parallel to the longitudinal axis of said lure.
2. The diving lip according to claim 1, wherein at least one of the upper surfaces of the rear, intermediate and front sections is concave.
3. The diving lip according to claim 1, wherein the upper surfaces of the rear, intermediate and front sections may comprise between 45 and 50%, between 15 and 20% and between 30 and 40%, respectively, of the longitudinal extent of diving lip.
4. The diving lip according to claim 1, and further comprising a convex transition zone disposed between the rear and intermediate upper surfaces.
5. The diving lip according to claim 4, wherein the fishing line connector loop projects from the convex transition zone.
6. The diving lip according to claim 1, and further comprising a concave transition zone disposed between the intermediate and front upper surfaces.
7. The diving lip according to claim 1, and further comprising a keel extending from the lure along lower portions of the rear and intermediate sections of the diving lip.
8. The diving lip according to claim 1, wherein the angle \u03b1 is between 25\xb0 and 35\xb0, and the angle \u03b2 is between 45\xb0 and 55\xb0.
9. The diving lip according to claim 1, wherein the rear upper surface is between 45 and 50% of a total side profile length of the diving lip.
10. The diving lip according to claim 9, wherein the intermediate upper surface is between 15 and 20% of said side profile length.
11. The diving lip according to claim 9, wherein the front upper surface is between 30 and 40% of said side profile length.
12. The diving lip according to claim 1, wherein the longitudinal axis of the fishing lure is generally horizontally disposed as the lure moves through water.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for producing a multi-amine functional oligomer, comprising
copolymerizing carbon monoxide and at least one olefin by a free-radical mechanism to form a copolymer which comprises at least one carbonyl group,
reacting the at least one carbonyl group of the resultant copolymer with hydroxylamine to form a multi-oxime functional oligomer, and
reducing the multi-oxime functional oligomer to a multi-amine functional oligomer;
wherein the reduction proceeds by hydrogenation using molecular hydrogen and wherein the hydrogenation proceeds in the presence of ammonia.
2. The method as claimed in claim 1, wherein the at least one olefin is an olefin mixture comprising
A) an olefin selected from the group consisting of ethylene, propylene, and mixtures thereof, and
B) at least one further terminal andor internal olefin different from A).
3. The method as claimed in claim 2, wherein component (A) is ethylene.
4. The method as claimed in claim 2, wherein component (B) is selected from the group consisting of 1-butene, 2-butene, butadiene, the isomers of pentene, hexene, heptene, octene, isooctene, nonene, decene, undecene, dodecene, styrene, alpha-methylstyrene, 3-methylstyrene, 4-methylstyrene, and mixtures thereof.
