摘要:
A multi-media device interface (18) couples a multi-media device (1:6) to a portable electronic device (10). Multi-media and other information can be loaded into the portable electronic device (10) from the multi-media device (16) or stored in the multi-media device (16) from the portable electronic device (10). The multi-media device interface (18) queues commands to the multi-media device (16) from the portable electronic device (10) while the multi-media device (16) completes a previously-issued command.

摘要:
A process for the double bond isomerization of an olefin, which process comprises contacting a feed comprising the olefin with an isomerization catalyst, wherein prior to contacting the feed with the isomerization catalyst one or more components of the feed are pretreated by contacting with a pretreating material which comprises a zeolite which has a pore size of at least 0.35 nm; a plant which is suitable for carrying out the isomerization process; and a process for treating an olefin mixture which comprises a linear α-olefin and a vinylidene olefin which is isomeric to the linear α-olefin and which is of the general formula CH2═C(R1)R2, wherein R1 represents an ethyl group and R2 represents a linear 1-alkyl group, which process comprises isomerising the vinylidene olefin to form a double bond isomer of the vinylidene olefin by contacting a feed comprising the olefin mixture with an isomerization catalyst, and separating the linear α-olefin from the double bond isomer of the vinylidene olefin, wherein prior to contacting the feed with the isomerization catalyst one or more components of the feed are pretreated by contacting with a pretreating material which comprises a zeolite which has a pore size of at least 0.35 nm.
摘要:
A process for the conversion of C16 and/or C8 alpha olefins to internal olefins encompasses passing the C16 and/or C18 alpha olefins through a bed of solid acid silica-alumina catalyst at a maintained operating temperature of between about 70° to about 140° C. The amount of residual alpha olefin content in the isomerized internal olefin mixture is less than 10 weight percent. The isomerized internal olefin mixture further preferably contains less than about 25 weight percent of the C1 and C6-C8 isomers and, optionally, the C9 isomer when a C18 is being converted, the remainder being the C2-C5 olefinic isomers. Such isomerized internal olefin mixtures have particular applicability as paper sizing compositions and as drilling fluids.
摘要:
The holder comprises a base adapted to be attached to associated apparatus such as a neck harness and two struts extending from the base and shaped and oriented to hold a harmonica by its ends. The holder fits snugly around the harmonica and the structure from the base to the structure which holds the harmonica approaches the harmonica through a narrow lateral space at the center of the back of the harmonica to enable cupping of the musician's hands around the harmonica.
摘要:
In a method for erecting the jacket of a cable net cooling tower which has a center mast, which method includes hoisting the jacket by lifting forces produced by hoisting means located at the top of the center mast, the jacket is suspended from pulling members composed of groups of threaded steel rod units, each unit being composed of a succession of individual steel rods joined together at their ends by threaded sleeves, the lifting forces are transmitted to the steel rod units by setting elements detachably connected to the steel rods, and the uppermost individual steel rod of each unit is removed when it is no longer in force transmitting relation with the hoisting means.
