| 81 | Mixing capsule | US825395 | 1977-08-17 | US4136775A | 1979-01-30 | Saul Zaltsman |
| A mixing capsule for mixing a first material with a second material (e.g. to prepare a dental silver amalgam) comprises a pair of tubular housing sections removably attached to each other and defining between them a first chamber for receiving the first material to be mixed. The second housing section includes a partition integrally joined to its inner surface by a thin connecting web, and a tubular neck above the partition. A plunger is disposed in the neck of the second housing section, the lower face of the plunger defining with the partition a second chamber for receiving the second material to be mixed, the plunger being depressable to cause the partition to be severed along its connecting web from the inner surface of the second housing section and thereby to cause the material in the second chamber to drop into and mix with that in the first chamber. | ||||||
| 82 | Stopper assembly | US527935 | 1974-11-27 | US3991896A | 1976-11-16 | Eduardo V. Miranda |

| 83 | Cartridge for storing and mixing at least two independent ingredients | US571523 | 1975-04-25 | US3951387A | 1976-04-20 | Fuller Warden; Eugene W. Lewis |
| A disposable cartridge or capsule for storing at least two independent ingredients preloaded therein in mutually sealed relationship, and selectively combining and mixing the ingredients to provide a substantially homogeneous compound. The cartridge comprises a sectional housing having mixer means rotatably mounted therein, said mixer means being carried by sealing means which cooperates with the housing for providing at least two sealed compartments therein in one position of the sealing means and opening communication between the compartments in a second position of the sealing means. Subsequent to a mixing operation, one of said housing sections may be separated from the other housing section and released from engagement with the sealing means and mixing means whereby the mixture may be stored in said removed housing section for use. | ||||||
