Patent GB-945454-A (GB)
Title: Improvements in or relating to automatic telephone systems
Inventor: BROWELL LESLIE JAMES
IPC: H04M3/54
Filed: 1962-08-14
Abstract: 945,454. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Aug. 14, 1962, No. 31137/62. Heading H4K. A subscriber having two numbers, e.g. business and residental, may cause incoming calls to be directed from one substation SSN to the other SST by looping the line, operating a locking key KD to connect in a rectifier MRA and then hanging up. This is accomplished by means of a relay set interposed between the line and equipment terminals DIR, EQ of the I.D.F. The looping of the line at SSN causes the line circuit SLCN to return earth on terminal S to energize relays TA, TC. If the subscriber dials, these relays produce no effect, but if he now operates key KD the line relay releases followed by TA and relay OT (which is fed from negative battery) energizes and holds TC. When the subscriber is called, a marking on wire MKR is extended to the line circuit SLCN which applies earth to terminal S to energize relay TS and thus direct the call to the substation SST. Moreover, earth is connected to terminal K to energize the cut-off relay of the line circuit SLCT, which holds relay OT for the duration of the call even though the key UD may be restored. Specifications 890,235 and 909,237 are referred to.

Title: Process for purifying phenols
IPC: C07C37/86
Filed: 1965-07-27
Abstract: Phenols which have been prepared by the partial oxidation of a secondary alkyl aromatic hydrocarbon followed by acid-catalysed cleavage of the hydroperoxide so formed may be purified at least partially of carbonyl compounds by neutralizing the cleavage reaction mixture, separating from the neutralized mixture a fraction containing the phenol and carbonyl impurities, mixing this with water and contacting the resulting mixture at elevated temperature with a catalytic composition consisting of silica-alumina, silica-zirconia, alumina-zirconia or silica-alumina-zirconia, thus converting the carbonyl compounds to compounds having lower boiling points and distilling these compounds from the phenol.  The process is particularly suitable for the purification of phenol itself, obtained by the acid cleavage of cumene hydroperoxide, but may also be used for the purification of phenols obtained by the acid cleavage of the peroxides of o-isopropyltoluene, m - isopropyltoluene, p - isopropyltoluene, p-diisopropylbenzene, sec.-butylbenzene and b -isopropylnaphthalene. The temperature used for carrying out the treatment with the catalyst is in the range 150-250 DEG  C.
