  • Patent number: 4211537
    Abstract: A system for supplying hydrogen to an apparatus which utilizes hydrogen, contains a metal hydride hydrogen supply component and a microcavity hydrogen storage hydrogen supply component which in tandem supply hydrogen for the apparatus. The metal hydride hydrogen supply component includes a first storage tank filled with a composition which is capable of forming a metal hydride of such a nature that the hydride will release hydrogen when heated but will absorb hydrogen when cooled. This first storage tank is equipped with a heat exchanger for both adding heat to and extracting heat from the composition to regulate the absorption/deabsorption of hydrogen from the composition. The microcavity hydrogen storage hydrogen supply component includes a second tank containing the microcavity hydrogen supply. The microcavity hydrogen storage contains hydrogen held under high pressure within individual microcavities. The hydrogen is released from the microcavities by heating the cavities.

  • Patent number: 4198049
    Abstract: A toy game of skill between two players is described wherein a track having a first end and a second end includes at least one surface extending between the first and the second end. Located at each end of the track and integrally mated with the track is a projectile launcher. At least one projectile, a small heavy spherical object, is ejected forcibly by the projectile launcher along the surface of the track. Resting on the track is an object member. The object member includes a self-propelling internal locomotion device which moves the object member back and forth reversibly between the projectile launchers located on the ends of the track.

  • Patent number: 3948886
    Abstract: Described herein are novel 6-alkylthio and 6-arylalkylthio purine 3',5' cyclic nucleotides variously exhibiting adenyl cyclase and (in animal studies) tumor inhibitory properties, interferon potentiation, antiviral activity, and the ability to activate adenosine 3',5'-cyclic phosphate-dependent protein kinase while enjoying resistance to phosphodiesterase hydrolysis superior to that of its naturally occuring analog. The compounds are obtained by alkylation of the corresponding 6-thio nucleotide, which is in turn provided by a novel synthetic route.
