Patent ES-8201200-A1 (ES)
Title: Catalytic steam reforming of hydrocarbons.
IPC: C01B3/38
Filed: 1981-01-21
Abstract: The hot effluent from the catalytic steam reforming of a major portion of a fluid hydrocarbon feed stream in the reformer tubes of a primary reformer, or said effluent after secondary reforming thereof, is mixed with the hot effluent from the catalytic steam reforming of the remaining portion of the feed discharged from the reformer tubes of a primary reformer-exchanger. The combined gas steam is passed on the shell side of the reformer-exchanger countercurrently to the passage of feed in the reformer tubes thereof, thus supplying the heat for the reforming of the portion of the feed passed through the reformer tubes of the reformer-exchanger. At least about 2/3 of the hydrocarbon feed stream is passed to the reformer tubes of said primary reformer, heated by radiant heat transfer and/or by contact with combustion gases, at a steam/hydrocarbon mole ratio of about 2-4/1. The remainder of said feed stream is passed to the reformer tubes of said reformer-exchanger at a steam/hydrocarbon mole ratio of about 3-6/1. The reformer shell of the reformer-exchanger is internally insulated by a refractory lining or by use of a double shell with passage of water or a portion of the feed material between the inner and outer shells. There is no significant difference between the pressure inside and outside of the reformer tubes of said primary reformer-exchanger.
Patent ES-8202439-A1 (ES)
Title: Bar code reader system.
IPC: G06K7/10
Filed: 1981-02-02
Abstract: A reader system for optically scanning a bar code and processing the resulting video signals to produce corresponding digital signals is disclosed. The scanner comprises a camera having an image sensor which converts the varying black and white bar code image into a corresponding analog video signal. This signal is fed to a dynamic threshold detector which tracks the midpoint voltage value of the video signal and applies this value to a comparator, where it is compared to the analog video signal. The output of the comparator provides a train of logic states "0" and "1" representing video levels below and above the midpoint voltage value, respectively, thus producing a digitalized video signal corresponding to the bar code. The digital signals are filtered to mask single bit aberrations, with the filter producing a series of logic "0"'s and "1"'s at the clock rate of the system, each of which represents the output of a single "pixel", or picture element, of the image sensor, the output level indicating whether the pixel has sensed a black or white bar. The number of consecutive pixels having "0" or "1" output levels are counted and compared to preset values to determine whether wide or narrow code bars are being sensed, and this information is stored in digital form in one of two serial memories. At the same time, the total number of bars scanned is counted, and the memory is inhibited when the count equals the number of bars in the code. At the completion of a first scan of the bar code image, the storage of informatiion is switched to the other serial memory and the bar code scanning process is repeated while the data just stored in the first memory is processed, for example, in a conventional bar code-to-numeric or alpha-numeric converter for display. Multiple scans of the bar code insure an accurate readout.
