Impact target capsule and impact compression apparatus
View Patent ↗A target capsule includes (A) a pedestal having a central projection, (B) a pedestal aid attached to the central projection so as to define a sample-loading assembly, and (C) an impact-receiving member, wherein the components (A), (B), and (C) are detachable from each other. The impact target capsule can be readily loaded with a sample, allows the sample to be easily retrieved after application of impact pressure, and can be used repeatedly, and thereby the capsule can be preferably used as an impact compression apparatus in combination with a single-stage powder gun or a single-stage gas gun.
1. A reusable impact target capsule, comprising:
(A) a pedestal having a central projection and an annular groove surrounding the central projection;
(B) a pedestal aid having a ring shape and fitted into the annular groove of the pedestal, so as to define a sample-loading assembly having a cavity for loading a powder sample formed between the central projection of the pedestal and an inner wall of the ring of the pedestal aid;
(C) an impact-receiving member detachably mounted on the pedestal aid;
wherein the elements (A), (B) and (C) are detachable from each other and the inner surfaces of the sample-loading assembly are coated with a coating.
2. The reusable impact target capsule of claim 1 , wherein the impact-receiving member (C) has a non-penetrating cavity in the center thereof at the bottom of the pedestal aid, the cavity having the same cross-sectional area as that of the central projection.
3. A reusable impact target capsule, comprising:
(A) a pedestal having a central projection; and
(B) an impact-receiving member having a central cavity for receiving the central projection of the pedestal, so as to define a sample-loading assembly having a cavity for loading a powder sample formed between the central projection of the pedestal and the central cavity of the impact-receiving member;
wherein the elements (A) and (B) are detachable from each other and the inner surfaces of the sample-loading assembly are coated with a coating.
4. The reusable impact target capsule of claim 1 , wherein (A) the pedestal and (C) the impact-receiving member have the same shape.
5. The reusable impact target capsule of claim 1 , further comprising an impact inducing member.
6. The reusable impact target capsule of claim 5 , wherein the impact-inducing member has gas holes and/or gas grooves to release gas that interferes with transmission of the shock waves.
7. An impact compression apparatus comprising:
the reusable impact target capsule of claim 1 ; and
a single-stage powder gun, a single-stage gas gun, or gunpowder.
8. The impact compression apparatus of claim 7 , wherein the reusable impact target capsule further comprises an impact inducing member.
9. The impact compression apparatus of claim 8 , wherein the impact-inducing member has gas holes and/or gas grooves to release gas that interferes with transmission of the shock waves.
10. The reusable impact target capsule of claim 3 , further comprising an impact inducing member.
11. The reusable impact target capsule of claim 10 , wherein the impact-inducing member has gas holes and/or gas grooves to release gas that interferes with transmission of the shock waves.
12. An impact compression apparatus comprising the reusable impact target capsule of claim 3 , and a single-stage powder gun, a single-stage gas gun, or gunpowder.
13. The impact compression apparatus of claim 12 , wherein the reusable impact target capsule further comprises an impact inducing member.
14. The impact compression apparatus of claim 13 , wherein the impact-inducing member has gas holes and/or gas grooves to release gas that interferes with transmission of the shock waves.
