Title: Production of phenols
Inventor: POEHLER GUENTER
IPC: C07C37/06
Filed: 1961-12-06
Abstract: Phenol itself and phenols substituted by one or two alkyl radicals containing from 1 to 4 carbon atoms are produced by dehydrogenating the corresponding cyclohexanols and/or cyclohexanones at temperatures between 200 DEG  and 500 DEG C. by means of a catalyst comprising as active metallic component cobalt and/or nickel in an amount of 3 to 50% by weight with reference to the whole catalyst, on a carrier which contains at least 20% of iron oxide with reference to the carrier and calculated as ferric oxide, the throughput being 0.1 to 5 Kg of the cyclohexanols and/or cyclohexanones per litre of catalyst per hour.  The carrier may contain only iron oxide but preferred carriers are those containing 30 to 80% by weight of iron oxide with the remainder being made up of aluminium oxide, silicon dioxide, titanium dioxide, zinc oxide or magnesium oxide or mixtures of these oxides. The additional oxides may enter into combination with the iron oxide. Advantageously the catalyst also contain 0.2 to 10% by weight with reference to the carrier of an alkali metal oxide or an alkaline earth metal oxide and 1 to 20% by weight with reference to the active metallic components of the catalyst of a catalyst promoter, e.g. the oxides of chromium, manganese, molybdenum, tungsten and vanadium. The dehydrogenation reaction may be carried out with an addition of hydrogen and preferably in the presence of steam. For each mole of initial material it is advantateous to use 0.5 to 10 moles of water but when the initial material contains cyclohexylamines it is desirable to use in addition 12 to 100 moles of water per mole of cyclohexylamines. The process is usually carried out in the vapour phase at atmospheric pressure although increased and reduced pressures may be employed. Specification 640,363 is referred to.ALSO:A catalyst used for dehydrogenation comprises as active metallic component cobalt and/or nickel in an amount of 3 to 50% by weight with reference to the whole catalyst, on a carrier which contains at least 20% of iron oxide with reference to the carrier and calculated as ferric oxide.

Abstract: 1,096,808. Semi-conductor timer circuits. MALLORY TIMERS Ltd. Oct. 11, 1966 [Oct. 11, 1965], No. 45349/66. Heading H3T. [Also in Division H2] A timer comprises a semi-conductor switch which becomes conductive when an input path is energized and causes a multivibrator to provide pulses to a timing circuit which, after the desired delay, terminates the conduction. Upon operating a switch 15 an SCR 13 becomes conductive to energize a D.C. motor 59. The SCR also supplies a free running multivibrator 21 to produce pulses which through rectifier 31 and timing resistor 31 progressively charge an adjustable capacitor 33. When the voltage across the capacitor is sufficient the combination of a PNPN diode and SCR 44, 43 breaks down so that the capacitor discharges through the SCR 13 and extinguishes it, so terminating the timing period. In Fig. 1 (not shown), a PNPN diode (35) takes the place of the breakdown combination 43, 44 while in Fig. 3 (not shown) the timer controls separate SCR's (13, 13<SP>1</SP>) feeding forward and reverse windings of the motor, the direction of running being determined by the direction in which the timing initiating switch (15) is operated. In this embodiment full-wave rectification of the multivibrator output is effected.

The matrix composition of alloys consisting entirely or predominantly of a stoichiometric TiNi phase e.g. near-stoichiometric Ti Ni and Co- or Fe-containing Ti Ni ternary alloys is ascertained by determining a characteristic of the internal friction of the alloy and comparing such characteristic with predetermined values indicative of matrix composition. The method may be applied during production of the alloy by removing a sample of molten alloy from the crucible, e.g. by way of a vacuum -lock system, solidifying the sample and then measuring, for example, the temperature at which its acoustic damping properties undergo a drastic change. The latter may be performed by torsion, or by striking a suspended bar and judging by ear whether or not the bar "rings", the bar "ringing" above the transition temperature and sounding leaden-like below this temperature. The results of such test will indicate that either Ni or Ti should be added to the melt to produce the desired matrix composition in the final alloy product.
