Patent ES-387789-A1 (ES)
Title: Apparatus for converting a decimal code into multifrequency code
IPC: H04W88/18
Filed: 1971-01-20
Abstract: Apparatus for converting n parallel decimal digits into K (less than n) tones, comprises in series: a converter for converting the n parallel digits into K parallel digits, a serializer, a repetition converter for identifying with a mark signal each digit which is repeated in sequence in the succession K digits, and a transcoder for translating the output digits of the repetition converter into control signals applied to a tone generator. Six of seven input decimal digits in 2-out-of-5 form are decoded to 1-out-of-10 form then 1-out-of-5 form (the latter conversion effectively taking each digit mod 5). The 1-outof-10 indications are used to indicate, for each digit, whether or not it is less than 5, and these indications together with a decoded version of the seventh input digit are combined logically to select, for each of the 6 decimal digits, either the 1-out-of-5 or the 2-out-of-5 representation. The selected representations are serialized &c. as mentioned above, to give a series of 6 tones, one per decimal digit, each tone being one of 16 frequencies, a particular one of these frequencies being used if the digit has the same value as the previous digit. The serializer is inhibited and an alarm tone emitted if the input is an invalid combination. The series of tones is used for paging a radiotelephone system subscriber.

Patent ES-456068-A1 (ES)
Title: Fractionation of aromatic streams
IPC: C07C1/00
Filed: 1977-02-18
Abstract: A fractionation scheme applicable to a transalkylation process in which an admixture of toluene and C9 alkylbenzene is converted to benzene and C8 alkylbenzene is disclosed. Transalkylation zone effluent containing C6 to C10+ alkylbenzene is passed into a fractionation zone wherein an admixture of benzene and toluene is withdrawn as a lower boiling fraction, and C8+ alkylbenzenes are withdrawn in admixture as a higher boiling fraction. The benzene and toluene fraction is introduced into a fractionator and separated therein. The C8+ fraction is fractionated into xylenes and C9+. The C9+ fraction is fractionated into a C9/C10 overhead fraction and C10+ bottoms fraction. Toluene and C9/C10 are then fed to the transalkylation zone. Significant savings in utilities are realized by using a xylene vapor fraction to reboil the column fractionating transalkylation zone effluent, and by using the C9/C10 vapor fraction to reboil the column fractionating benzene and toluene.
