    摘要: Organic hydrocarbon materials are produced from plentiful inorganic limestone type materials by: (1) reacting the limestone type materials with molten lithium metal to produce Li.sub.2 C.sub.2 (2) hydrolyzing the Li.sub.2 C.sub.2 to produce C.sub.2 H.sub.2, (3) catalytically reacting the C.sub.2 H.sub.2 with steam to produce CH.sub.3 COCH.sub.3, (4) pyrolyzing the CH.sub.3 COCH.sub.3 to provide ketene and methane, and separating the ketene. The ketene may then be decomposed to provide methylene, which can be reacted with an alkane, such as methane in an insertion chain reaction, to provide organic hydrocarbon materials. An in-place nuclear reactor can provide energy for the endothermic reactions of the system.

    摘要: A material is described which is useful in electrical current switching devices and is especially adapted to form the contact surface of the electrodes of electrical current switching devices which are employed in a vacuum environment. The contact material comprises a major component which is characterized by a melting point in excess of 1250.degree. C and a boiling point of less than 3500.degree. C. A small but effective amount of an element which provides antiwelding characteristics and in which said element has only minimum solubility within the major component. The balance is a minor constituent for providing a low resistance path for the electrical current to flow from one electrode to the other. Typical compositions includes a chromium matrix material which comprises in excess of 50% by weight of the contact material, up to about 1.5% of an antiwelding element for example bismuth and the balance essentially a high electrical and thermal conductivity element notably copper or silver. These ingredients are compounded and are formed into the shape of a contact material which is attached to the electrodes in electrical current switching devices.
