Title: Enciphering and deciphering apparatus for secret telegraph systems
IPC: H04L9/18
Filed: 1958-12-01
Abstract: 878,645. Code telegraphy. OLIVETTI & C. S.p.A., ING. C. Dec. 1, 1958 [Nov. 30, 1957], No. 38609/58. Class 40(3) In a start-stop secret telegraph system clear code signals are ciphered by mixing with cipher signals, the ciphered signals being further mixed with the cipher signals to provide deciphered signals which are compared with the original clear code signals. An alarm system is actuated if the signals compared differ. The ciphering is of the form in which two like inputs to the ciphering circuitry give a positive output while unlike inputs give a negative output, the supply of pulses being controlled by a distributer. The deciphered signal is taken to a local receiver for translation into intelligence at the transmitter. On presentation of a clear code signal at terminal 40 the start pulse causes the distributer 55 to make one revolution, the rest position of the brush 56 being shown dotted. As the brush contacts R the flip-flop 53 is caused to send a start pulse over the line 42, while at R<SP>1</SP> the flip-flop 54 sends a start pulse to the local receiver over line 45. The unit 50 comprises five cipher keys set to mark or space positions according to the cipher signal to be used with any one clear code signal. The first code element of the clear code signal switches relay 39 to either mark or space (a mark as shown in the Figure). Assuming the first cipher code element to be a space as indicated at 50<SP>1</SP>, when a is contacted potentials appear at points 77 and 81 in an adding circuit 51 which causes flip-flop 53 to be triggered, relay 41 to be energized and a space pulse to be sent over the line 42. Relay 85 is also energized and when a<SP>1</SP> is contacted potentials are applied at points 92, 93 in a second adding circuit 52. The output pulse of this circuit triggers flip-flop 54 and relay 44 moves its tongue to the position shown to pass a mark pulse, corresponding to the original mark pulse, to the local receiver over line 45. The pulse in line 45 is also fed to a comparator bridge circuit 97 and should this pulse and the original pulse not be the same relay 98 is actuated. This may operate an alarm or stop the apparatus working. The remaining code elements cause the apparatus to work in a substantially similar way and after the last code element the distributer contacts S and finally S<SP>1</SP>. This results in a stop signal being sent both to the line 42 and to the receiver on line 45.
Patent GB-928794-A (GB)
Title: Low temperature hydrocracking process
IPC: C10G65/12
Filed: 1960-11-10
Abstract: In the hydrocracking of a hydrocarbon distillate feed low in nitrogen compounds and containing aromatics, the feed is first hydrogenated catalytically to saturate at least 50% of the aromatics and thereafter is hydrocracked by contact with hydrogen and an acidic cracking catalyst having hydrogenating characteristics at 350 DEG -700 DEG F. and at least 400 p.s.i.g. to consume at least 250 SCF of hydrogen per barrel of the feed to product fractions boiling below the initial boiling point of the feed.  The feed may be a heavy naphtha, kerosene, light or heavy gas oil, light or heavy coker distillate, light or heavy cycle oil, heavy catalytic reformate or aromatic extracts from various fractions.  The total nitrogen content is first reduced to below 10 p.p.m. by conventional hydrofining followed by removal of hydrogen sulphide and ammonia. Hydrogenation of aromatics is effected over a metal of Group 6, 7, or 8 or oxide thereof, preferably platinum, supported on alumina, silica or kieselguhr, at 300 DEG -700 DEG F. at least 300 p.s.i.g. and LHSV of 0,3-5 using at least 2000 SCF of hydrogen per barrel of feed.  The total effluent can be passed to the hydrocracking which may be effected in a separate part of the same apparatus or hydrogen can be separated and various products separated.  The cracking catalyst is preferably a solid siliceous material, e.g. silica-alumina, silica-magnesia,silica-alumina-zirconia, acid treated clays or a synthetic chabazite, or may be alumina-aluminium chloride, fluorided magnesia, charcoal-alumina, or liquids, e.g. hydrogen fluoride-boron trifluoride, titanium tetrachloride, or aluminium chloride-hydrogen chloride-hydrocarbon.  With this is associated a hydrogenating component which may be a metal or oxide or sulphide thereof of Group 1b, 2b, 5, 6, 7 or 8 in an amount of 0,1-35% of the composition. Preferred are cobalt and/or nickel sulphide on silica-alumina.  At least 500 SCF of hydrogen per barrel of feed (including recycle) is present.  The pressure may be 500-2000 p.s.i.g. and the LHSV 0,2-5. The product is separated into hydrogen, C1-C3 or C4, gasoline which may be reformed and jet fuel, bottoms being recycled.
