Title: Production of aromatics-rich gasoline with low benzene content
Inventor: HARANDI MOHSEN N
IPC: C10G63/00
Filed: 1990-08-16
Abstract: PRODUCTION OF AROMATICS-RICH GASOLINE      WITH LOW BENZENE CONTENT                      Abstract A process for the production of high octane gasoline rich in aromatics but containing a relatively low concentration of benzene comprises the separation of C6 fraction of the gasoline feedstock into n-hexane and other C6 isomers.  The n-hexane and C7+ streams are catalytically reformed to produce a reformate with a diminished yield of benzene.  The reformate is separated and the C6- reformate fraction containing benzene is alkylated employing a zeolite catalyst such as ZSM-5 and preferably methanol or propylene as the alkylating agent.  The alkylate comprises high octane C7+ alkylaromatics.

Title: Method and apparatus for improving the accuracy of fire
Inventor: PICCOLRUAZ HEINZ
IPC: F41G3/14
Filed: 1990-01-24
Abstract: ABSTRACT            A method for improving the accuracy of fire of shots from a firing installation is described, in which a surveying means surveys the trajectories of pilot shots and the thus determined pilot trajectories are used for correcting the firing elements of the real shots.  One or more pilot shots are fired in the direction of possible and/or known targets and from the pilot trajectories are calculated and stored trajectory-influencing, predetermined parameters and subseq-uently or directly are incorporated into the calculation of the firing elements.  A simplified method variant determines by surveying only the initial portion of the shot trajectory, the departure error of the effector and which is incorporated into the calculation of the firing elements.

Abstract: PARALLEL PROCESSING SYSTEM                 ABSTRACT OF THE DISCLOSURE         A parallel processing computer system is describes.  The system includes an arbitrarily large number of processing elements hierarchically connected to each other.  In operation, when a program executes a parallel do instruction statement, parallel tasks are created, one for each iteration of the parallel do instruction.  Each newly-created task is the child task of the task that executed the parallel do statement. Each child task inherits the memory state of the parent task, and while each child task executes, the parent task is suspended,  When the child tasks complete, their memory states are merged to form the new memory state of the parent task which then resumes execution.

Such device includes a shift register for receiving input data; and data processing means, including a pseudorandom nonlinear sequence generator, for executing the following data processing routine a selected number of cycles to provide output data: processing the contents of said shift register with a key signal to provide initially processed data:  initializing the pseudorandom nonlinear sequence generator with the initially processed data;  running the pseudorandom nonlinear sequence generator to generate a keystream;  segregating portions of the keystream; processing said segregated portions of said keystream with a portion of the data in the shift register, to provide a block of processed data; and shifting said block of processed data into the shift register. To further increase the randomness of the pseudorandom keystream generator, and hence the encryption security, the data processing routine segregates the keystream in accordance with a routine wherein the beginning of said segregated portion is provided at a time related to the beginning of the keystream in response to a duration indication; segregates ovary nth bit of the keystream from said beginning of said segregated portion for a selected number of segregated bits in response to a frequency indication; and provides said initially processed data by first processing said shift register contents and said key signal and then rotating data produced by said first processing in response to a rotation indication.  The duration indication, the frequency indication and the rotation indication are each separately provided for each of the cycles and may be different for each of the cycles.
