Abstract

A motion-powered liquid sprayer that can increase the number of rotations of the pump relative to each rotation of the wheel or axle is provided. The sprayer can include a gearing assembly that employs gears to increase the number of pump revolutions as a function of the wheel or axle rotation. The sprayer can also include a gear pump that employs an over-capacity or enhanced gullet together with blow-by spacing to control consistent liquid flow relative to variable motional velocities. Further, the sprayer can include a vertically adjustable nozzle as well as a free reverse rotation wheel hub.

Claims

1. A system that forms a wire harness covering according to a predetermined three-dimensional geometry, comprising:

a wire harness;

an injection mold that includes two mold halves that define a cavity therebetween and that is substantially flat in shape that forms a partially-cured wire harness covering having an intermediate, substantially two-dimensional shape; and

a post-molding fixture that orients the partially-cured wire harness covering in accordance with the predetermined three-dimensional geometry,

wherein the partially-cured wire harness covering is positioned in the post-molding fixture within a first predetermined time after forming the partially-cured wire harness covering.

2. The system of claim 1, wherein the cavity comprises sub-cavities that form a corrugated covering of a predetermined thickness for the wire harness.

3. The system of claim 1, wherein the post-molding fixture comprises a base with a plurality of guide members that project from the base that orients the wire harness in accordance with the predetermined three-dimensional geometry.

4. The system of claim 3, wherein the plurality of guide members are pins.

5. The system of claim 4, wherein the pins are disposed in pin receiving holes in the base.

6. The system of claim 5, wherein a subset of the pin receiving holes are arranged about the base according to a predetermined configuration.

7. The system of claim 3, wherein the guide members are walls.

8. The system of claim 7, wherein the base has a top surface and the walls are upstanding from the top surface.

9. The system of claim 7, wherein at least one of the walls has a tab protruding from the at least one wall.

10. The system of claim 1, wherein the post-molding fixture is made from one of wood, fiberglass, composite, metal, alloy, or cardboard.

11. The system of claim 1 wherein the post-molding fixture comprises a tie that engages two portions of the harness for holding the harness in a fixed position while the covering cures.

12. A system that forms a wire harness, comprising:

a first mold portion and a second mold portion that define a cavity therebetween, each of the first mold portion and second mold portion is substantially flat in shape for forming a partially-cured wire harness covering having a substantially two-dimensional shape; and

a post-molding fixture that orients the partially-cured wire harness covering in accordance with a predetermined three-dimensional geometry.

13. The system of claim 12, wherein the cavity comprises sub-cavities that form a corrugated-like covering of a predetermined thickness that encapsulates the wire harness.

14. The system of claim 13, wherein a subset of the sub-cavities position the wire harness within each the first mold portion and the second mold portion.

15. The system of claim 12, further comprising a plurality of leader pins that facilitate alignment of the first mold portion with the second mold portion.

16. The system of claim 12, further comprising one of interlocking teeth, grooves, slots or channels that facilitate alignment of the first mold portion with the second mold portion.

17. A system of forming a three-dimensional wire harness, comprising:

a two piece mold that defines a cavity therebetween, wherein a combination of a polyol and an isocyanate facilitate a reaction injection molding (RIM) process to form a partially-cured wire harness covering having an intermediate shape; and

a means for post-molding that orients the partially-cured wire harness covering from the intermediate shape into a predetermined three-dimensional configuration.

18. The system of claim 17, further comprising means for corrugating the wire harness covering.

19. The system of claim 17, wherein means for post-molding is a wood, fiberglass, composite, metal, alloy or cardboard fixture.

20. The system of claim 17, further comprising means for establishing a predetermined cure time based at least in part upon the molding process in view of thickness of the wire harness covering.
