8. No bulging pockets with shells bumping and bruising your legs when walking and no more shells rattling in your pockets, all quiet and compact.
9. No more transferring shells to empty shooters side pockets from the other side pockets.
10. Release mechanism closes the bottom of the tube preventing loss of shells while readying the next shell for release.
11. Vest will handle a wide variety of shell sizes; 12-gauge, 16-gauge and 20-gauge with equal proficiency.
13. The spring mechanism requires very little movement to release a shell into your palm with simple finger-thumb pressure to compress the springs.
14. You have complete freedom of movement in the arms and shoulders with the vest fully loaded for weight is evenly distributed to the back and shoulders.
15. A woman or young person can easily handle the weight and shell release.
16. Wearing gloves on cold days will not hamper release of shells into your palm.
17. Specially designed stainless steel springs with an eye or circle on each end acts as a ball bearing in the fabric and will not rust or cut the fabric.
18. The most shells (50) carried in a vest on your chest comfortably ever designed. You hardly know you are carrying two boxes of shells.
19. Shells are shielded from the elements in a vest with removable straps or harness that is adjustable for all to use, large or small.
20. This invention provides a shell retainer and dispensing vest that can be worn under or over the shooters favorite hunting jacket or vest if he so desires.

an impaction station for performing impaction testing using the assembled impactor;
a cup manifold recovery station for recovering sample material from the impactor cups in a solvent;
an impactor head cleaning station; and
at least one handling system for assembling the impactor for impaction, and for subsequently disassembling the impactor and delivering the cup manifold and the impactor head to their respective stations.
2. A system as claimed in claim 1 further comprising a nozzle manifold cleaning station, the handling system being adapted to disassemble the nozzle manifold from the impactor head and deliver the nozzle manifold to its cleaning station.
3. A system as claimed in claim 1, comprising an impactor head handling device having a movable support for carrying the impactor head between stations and an engagement device for releasably coupling the nozzle manifold to the impactor head.
4. A system as claimed in claim 3 further comprising a nozzle manifold cleaning station and a handling system for delivering the nozzle manifold to the nozzle manifold cleaning station.
5. A system as claimed in claim 3 in which the engagement device comprises at least one movable finger for engaging a peripheral region of the nozzle manifold, to couple it to the impactor head.
6. A system as claimed in claim 1, comprising an impactor head handling device having a movable support for carrying the impactor head, the support having a first axis of motion for advancingretracting the impactor head with respect to the cup manifold to assembledisassemble the impactor.
7. A system as claimed in claim 6, wherein the impactor head has a second axis of motion for moving the impactor head from one station to another.
8. A system as claimed in claim 6, in which the impactor head handling device is adapted to exert a controlled biasing force upon the impactor head, to urge it toward the cup manifold.
9. A system as claimed in claim 8, comprising an impactor head position sensor for determining when the impactor head is in an acceptable position with respect to the cup manifold.
10. A system as claimed in claim 8 in which one of the impactor head and the cup manifold has a resilient mounting for equalising pressure across the area of contact of the impactor head and the cup manifold.
11. A system as claimed in claim 8 in which the impactor head is fixedly coupled to the movable support and is separated from it by resilient spacers for equalising pressure across the area of contact of the impactor head and the cup manifold.
12. Apparatus for use in an impaction testing arrangement, the apparatus comprising an impactor which has a cup manifold defining multiple impaction cups and an impactor head defining transfer passages each communicating with a respective nozzle, so that in the assembled impactor a route is defined for through-flow via the impaction cups, the nozzles and the transfer passages, the apparatus further comprising an impactor head clean up device having an exposed contact plate provided with multiple fluid outlet apertures connected to a fluid source, the fluid outlet apertures being positioned to correspond to openings of the transfer passages in the impactor head, so that when the impactor head is presented to the seal plate, fluid is able to be output into the transfer passages to clean them.
13. Apparatus as claimed in claim 12, in which the fluid outlet apertures communicate with recess formed in the contact plate.
14. Apparatus as claimed in claim 12, in which the contact plate is provided with a mounting which prevents it from moving.
15. Apparatus for use in an impaction testing arrangement, the apparatus comprising an impactor which comprises a cup manifold defining multiple impaction cups, an impactor head defining transfer passages, and a nozzle manifold which defines multiple nozzles and is disposable between the cup manifold and the impactor head, so that in the assembled impactor a route is defined for through-flow via the impaction cups, the nozzles and the transfer passages, the apparatus further comprising a nozzle manifold wash module comprising first and second wash manifolds shaped to receive the nozzle manifold between themselves, an opening mechanism for moving the first and second wash manifolds with respect to each other between (a) an open configuration which permits the nozzle manifold to be introduced between them and (b) a closed configuration in which each nozzle is contained in a sealed enclosure defined between the first and second wash manifolds, and ports which communicate with the said sealed enclosures formed by the first and second wash manifolds in their closed configuration and which are connectable to a fluid source for passing fluid through the sealed enclosures to carry out washing of the nozzle manifold.
