Title: Colorimetric testing and measuring device for gases
Inventor: EVERS WOLFGANG
IPC: G01N31/22
Filed: 1992-06-26
Granted: 1995-08-01
Abstract: An improved measuring apparatus for the colorimetric indication of gases is disclosed.  The apparatus comprises a carrier that is impregnated with a solution of a moisture retainer and a detection indicator.  A mixture of sulfolane and diethylphthalate is used as the moisture retainer.  To measure hydride gases, such as arsine or phosphine, the indicator con-sists of palladium tetramine chloride.  The impregnating solution may be applied to a paper carrier or to a granular silica gel carrier.  Due to the presence of the moisture retainer, the moisture required for the indicating reaction remains on the indicator carrier for a longer period of time, both during stor-age of the device and during measurements, when the carrier is exposed to the gaseous substance that is to be indicated.

Title: Hydrocarbon fuel and fuel systems
Inventor: TALBERT WILLIAM L
IPC: C10L1/18
Filed: 1990-07-31
Granted: 2003-02-11
Abstract: A liquid hydrocarbon gasoline is provided by rem-oving both the volatile and non-volatile components from C4-C12 gasoline to yield either a C6-C9 ar a C6-C10 intermediate gaso-line. The intermediate gaso-line of this invention can be combusted, in a stndard carbureted engine with less C4 and/or C5 priming than is required in standard C4-C12 gasoline, and thus provides adequate cold en-gine starting ability with lower Reid Vapor Pressure.    The C6-C9 and C6-C10 fuel can be combusted in a mod-ified engine without any pri-ming by gasiying the fuel.    The fuel is gasified by heat-ing it in a chamber in the absence of air; mixing the gas with air and then combusting the mixture. The gasified fuel is advantageous because it doesn't condense into droplets and thereby is combusted more completely in the gaseous state enhancing combustion efficiency. The fuels of this invention better facilitate alcohol addition than current gasolines because of their lower Reid Vapor Pressures.

Granted: 1999-01-26
Abstract: Selective tributary switching is realized in a bidirectional transmission system by selectively switching, in accordance with the same rules governing the set-up and take down procedures of full line-switching, only that portion of the bandwidth of the particular line which has been provisioned to be line-switched. The remaining bandwidth can be left unprotected or, by for the first time combining line-switched ring functionality with path-switched ring functionality in the same ring transmission system, some remaining bandwidth can be path-switched.  Furthermore, another degree of switching freedom is achieved in a four optical fiber bidirectional ring transmission system by selectively span-switching, but not ring-switching, specific bandwidth on the line. To this end, communications circuit provisioning information is provided in the ring nodes as to whether a particular communications circuit should be line-switched or not and, if not, whether it should be span- switched, path-switched or left unprotected.
