Title: Processing c4 olefin streams for the maximum production of propylene
Inventor: GREENE MARVIN I
IPC: C07C6/04
Filed: 2004-07-12
Abstract: In order to maximize the production of propylene when the external supply of ethylene is limited, the C4 cut from a hydrocarbon cracking process is first subjected to autometathesis prior to any isobutylene removal and without any ethylene addition. This favors the reactions which produce propylene and pentenes. The ethylene and propylene produced are then removed leaving a stream of the C4~s and heavier components. The C5 and heavier components are then removed leaving a mixture of 1-butene, 2-butene, isobutylene, and iso-and normal butanes. The isobutylene is next removed preferably by a catalytic distillation hydroisomerization de-isobutyleneizer. The isobutylene-free C4 stream is then mixed with the product ethylene removed from the autometathesis product together with any fresh external ethylene needed and subjected to conventional metathesis producing additional propylene.

Title: Efficient method and apparatus for text entry based on trigger sequences
Inventor: GUTOWITZ HOWARD ANDREW
IPC: G06F/
Filed: 2004-09-09
Abstract: Languages based in whole or in part on ideographic characters such as Chinese, Japanese, and Korean, are often are entered in a computerized text-entry system in a two-phase process. In the first phase, symbols from a first pre-conversion set are entered (200), then in the second phase, these pre-conversion symbols are converted into a second set of post-conversion symbols (202). The method and apparatus is to automatic convert of pre-conversion symbols into post-conversion symbols without requiring an explicit conversion signal to be input by the user. It accomplishes this goal though the design of trigger sequences of keystrokes which are substantially functionally equivalent to an explicit conversion signal input by the user (210). An apparatus constructed according to the trigger sequence method is particularly well adapted for use on reduced keyboards, and in conjunction with predictive text-entry methods.
