...that in 1800 ether was first used by partyers as a fun diversion? Sniffing the gas led to hilarious and raucous laughter as people watched each other become more and more intoxicated and silly. Several doctors independently realized the value ether would have to anesthetize surgery patients. Of those who claimed rights to the "discovery," none had a happy ending. One had a seizure and died defending his rights. Another spent his life in an asylum because he had been denied acclaim. A third became addicted to chloroform and, in a New York City jail, he soaked a cloth in the drug, severed an artery and bled to death.

US Patent 6460531 - Toy rocket launcher
Estimated Patent Expiration Date:
November 6, 2020Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractA toy rocket launcher includes a rotatable, air pressurized assembly that allows for a plurality of rockets to be launched in sequence. In particular, the assembly uses a ratchet included in a base supporting member, where the ratchet is rotated by a piston included in a launch tube connected between the base supporting member and a source of pressurized air (i.e., a manually-operated bellows). The rockets are disposed on separate launch tubes, the launch tubes open at their terminations and disposed such that each tube will receive, in sequence, the pressurized air supplied by the bellows. A guard ring structure may be included with the launcher to prevent a launch should an individual get too close and disturb the set up. | InventorsApplicationNo. 706626 filed on 11/06/2000US Classes:124/64, To create surge of pressure124/71With control for discharge of fluid pressureField of Search124/59, Having common supply to plural projector barrels124/63, Provided by movement of user-actuated, projector-mounted pressure member124/64, To create surge of pressure124/65, By plunger moving within cylinder124/71, With control for discharge of fluid pressure124/72For continual projection of successive projectiles (e.g., for "rapid fire", etc.)ExaminersPrimary: Carone, Michael J.Assistant: Chambers, Troy Attorney, Agent or FirmUS Patent References2993297, 3009453, 3628416, 3752082, D248498, 4223472, Toy projectile launching deviceIssued on: 09/23/1980 Inventor: Fekete , et al.4848307, Toy air pistol for launching missile bullet Issued on: 07/18/1989 Inventor: Tsao5323755, Toy gun Issued on: 06/28/1994 Inventor: Hsieh D351432, 5415152, Method of launching multiple fireworks projectiles Issued on: 05/16/1995 Inventor: Adamson, et al.
