Abstract: 1,191,758. Solvent-extracting oils. TEXACO DEVELOPMENT CORP. 5 Dec., 1968 [22 Dec., 1967], No. 57714/68. Heading C5E. The process relates to the solvent-extraction of a hydrocarbon oil 1 with N-methyl-2- pyrollidone (NMP) to produce a raffinate phase 5 and an extract phase 4, similar to the process described in Specification 1,153,099. In the present process, the raffinate is contacted with water to separate a solvent phase 12 from an oil phase 13 which is distilled at 17 and the bottoms 25 vacuum steam stripped at 26 to produce a stream 30 of NMP and water which is delivered through 9 to be mixed at 8 with the raffinate. The extract 4 is similarly treated at 37, 54, 57 to produce a water/NMP stream 60 for mixing with the stream 30. Dried NMP is returned from tower 68 to the extractor 2 through line 3, and dried NMP may be delivered at 70 to the tower 68, e.g. where gas oil is being treated.

Abstract: 1372217 Code converting V D O ADOLF SCHINDLING AG 14 Dec 1971 [15 Dec 1970] 58088/71 Heading G4H A code converting system comprises counters 1, 2 which are fed from a pulse generator 4 and which accumulate respective counts in the old and the new codes, a coincidence circuit 5 which compares the count ZA1-ZA11 in the old code with input data E12-E22 in that code, and a control circuit 3 which stops the count and resets the counters when the count is the same as the input data. As shown, input data from a barometric altimeter is converted by a shaft encoder into Gillham code and fed to the comparator 5; when the count ZA1-ZA11 reaches the value of this data, an output signal 16 inhibits a gate 10 and sequentially triggers two monostable devices 11, 12. Output A1 of device 11 opens a store 6 so that the output of counter 2 (which represents the value of the input data in BCD code) may be subsequently fed to a digital display 8 via a decoder 7; output A2 of device 12 then resets the counters. Each of the eleven pairs of bits fed to comparator 5 is applied to an EXCLUSIVE-OR arrangement of NOR-gates 13-15, Fig. 2 (not shown), the outputs of which are connected so as to form a WIRED-AND circuit. The counter 1 comprises a synchronous counter 18, Fig. 3 (not shown), for the Srst three pulses (outputs ZA1-ZA3) and a counting network (19) connected thereto (for outputs ZA4-ZA11), both counter 18 and network 19 comprising bi-stable trigger stages. Suitable choice of the counters 1, 2 make it possible to convert between codes other than Gillham and BCD.
