We claim:
1. The combination comprising a plastic-bonded ring magnet and a ring-shaped basic body adapted to fix the magnet onto a shaft which penetrates through the magnet and the basic body, wherein
each of said ring magnet and ring-shaped basic body respectively includes an outer surface which establishes an outside diameter, and an inner surface which establishes an inside diameter, and a pair of separated fronts;
said ring magnet being located at a first one of said fronts of said basic body;
said inside diameter of the basic body being smaller than the inside diameter of the ring magnet, and the respective outside diameters of the basic body and the ring magnet being substantially identical to one another, and wherein
the basic body includes at least one axially oriented channel-shaped recess extending between both said fronts of the basic body and which defines an inside wall; and wherein
said recess is filled with magnetic material.
2. A pole wheel including a first component that is produced in the form of a hollow magnet body of magnetic powder with thermoplastic binder, the first component having at least one north pole and one south pole in the circumferential direction and surrounding a shaft in a manner free of tensile and compressive stress, and a second component in the form of a retaining part of thermoplastic material seated solidly by press fit on the shaft and axially adjusting the first component, and connecting means for retaining the hollow magnet body axially and in a manner secure against relative rotation on the retaining part, the connecting means being embodied integrally with one of the two components, the improvement wherein the connecting means (5) are embodied integrally with the first component (3), and that the second component (4) has recesses (17) into which the connecting means (5) are formed by injection molding, wherein the second component (4) has a first face end (12) and a second face end (13), with the second face end (13) being positioned adjacent the first component (3), wherein the recesses (17) are in communication with both face ends, and the recesses, where they communicate with the first face end, have a cross section which is larger than their cross section at the second face end.
3. The pole wheel of claim 2, wherein the recesses (17) are embodied as longitudinal grooves that are partly open toward the circumference of the second component (4).
4. The pole wheel of claim 1, wherein the first opening cross sections and the second opening cross sections are positioned and located with respect to each other so that they form an opening angle which enables easy removal of the second component from a mold.
5. The pole wheel of claim 3, wherein the second component (4) has a first face end (12) and a second face end (13), with the second face end (13) being positioned adjacent the first component (3), wherein the recesses (17) are in communication with both face ends, and the recesses, where they communicate with the first face end, have a cross section which is larger than their cross section at the second face end.
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 can end configured to be attached to a can body, the can end comprising:
an end panel including a movable portion;
a score line in the end panel defining an openable panel portion;
a pull tab including a nose, a handle capable of being actuated such that the pull tab ruptures the score line, the pull tab is coupled to the end panel at a rivet that is disposed between the nose and the handle such that the handle overlays the movable portion of the end panel;
the entire movable portion is disposed on a side of the rivet opposite the nose, the movable portion is deformable between:
an up position in which the movable portion is convex, as viewed from above the can end, such that a portion of the movable portion contacts a portion of the handle, and
a down position in which the movable portion is concave, as viewed from above the can end, such that the movable portion is spaced apart from the handle forming a gap between the handle and the movable portion to facilitate access by a user’s finger to the handle for actuating the handle;
wherein the movable portion is deformable from the up position to the down position before the handle has been actuated and the score line is ruptured.
2. The can end of claim 1, wherein a periphery of the end panel defines a reference plane, the movable portion in its up position extends upwardly relative to the reference plane and the movable portion in its down position extends downwardly relative to the reference plane.
3. The can end of claim 1, wherein the movable portion is deformed from its up position to its down position after manufacturing of the end.
4. The can end of claim 3, wherein the movable portion is deformed from its up position to its down position by the user.
5. The can end of claim 1, wherein the deformation of the movable portion is elastic.
6. The can end of claim 1, wherein the movable portion, after being deformed to the down position, remains in the down position after the handle has been actuated and the score line is ruptured.
