2. [ss] John York Cabot's "The Last Analysis": "Forbes & Barton had the discovery of the century; a machine that could foretell a crminal's acts!"

   I haven't read it, but this description sounds like Henry Kuttner & C L Moore's "What You Need".
5. [ss] Charles R Tanner's "The Stillwell Degravitator": "Stillwell saw only good in his machine that overcame gravity - until he put it to practical use!"
6. [ss] Gordan A Giles' "The Winking Lights of Mars": "Communication between two worlds, space travel to Mars - & it all depended on the Winking Lights."
