Title: Improvements relating to the recovery of selective solvents used in the treatment of oils
IPC: C10G21/28
Filed: 1936-04-30
Abstract: <PICT:0463905/III/1> In the recovery of selective solvents such as phenol, cresols, aniline, nitrobenzene, and furfurol, from the watery solvent recovered from the extract and raffinate obtained by extracting crude oils particularly lubricating oils with a selective solvent, the watery solvent in the vapour form is contacted, at a temperature sufficient to maintain the vapour state, with the original crude oils or with the substantially solvent-free extract thereof.  The solvents specified exhibit definite but limited mutual solubility with water and ready volatility in steam. Vaporized watery phenol is led upwardly in countercurrent to a stream of the original oil in a tower 2 filled with Raschig rings &c., and the phenol-oil solution is then discharged into a stripping tower 6, steam being blown off at 4.  Hot inert gas is supplied to tower 6 through a pipe line 7 to remove any absorbed moisture from the phenol-oil solution and after freeing from moisture and traces of phenol in a condenser 9 is re-cycled to the tower 6.  The dry phenol-oil solution may be vaporized by a preheater 13 and rectified in column 14 with the aid of hot inert gas supplied from pipe lines 7 and 15.  Phenol is recovered from the vapours leaving the tower by means of a condenser 17 and separator 18; the inert gas is recycled as above and the oil from the base of the rectifier is re-supplied to the scrubber 2.  The temperature of the oil entering the scrubber is below 230 DEG  F. and preferably 213 to 225 DEG  F.; the scrubbing may be conducted under reduced pressure.

Filed: 1977-03-28
Abstract: 1524001 Multiplex data transmission A TEXIER 28 March 1977 [31 March 1976] 13016/77 Heading H4M A digital transmission system; whereby one or more main data transceivers 1 can communicate with a plurality, e.g. 3-5 of secondary data transceivers, the latter each in turn being able to communicate with the main transceiver(s) using digital words (octets) at first order, low rate(s) [submultiple(s) of 64 Kb/s], the latter rates occurring in a system as disclosed in Specification 1,501,165, wherein the low rate(s) are multiplexed to an intermediate rate, and further super-multiplexed to a high rate using a pseudo-random multiframing sequence, see Specification 1,498,223; is realized by dedicating a first group (one fifth) of the addresses of the octets in the intermediate rate (80 octet) frame to the main transceiver, the remaining addresses being dedicated to the secondary transceivers. A multipoint unit 8, see also Fig. 3 (not shown) functions to distinguish octets from the main transceiver by means of their addresses and to despatch each one of such octets to the secondary transceivers by replacing the address from the first group, with addresses from the remainder. Inversely, octets from the secondary transceivers are identified, and their addresses replaced by one from the first group corresponding to a main transceiver, see Fig. 2 (not shown). When one main transceiver communicates with S secondary transceivers, 1 + S being a sub-multiple of the number of octets in the intermediate rate frame, the addresses assigned to the main transceiver are those precisely divisible by 1 + S, all other addresses being assigned to the secondary transceivers.
