Title: Fail-safe logic circuits having a combined and/not function
IPC: H03K19/007
Filed: 1965-04-05
Abstract: 1,099,774. Logic circuits. COMPAGNIE DES FREINS ET SIGNAUX WESTING- HOUSE. April 5, 1965 [April 3. 1964], No. 14435/65. Heading H3T. A transistor circuit for producing the A.B function in a form represented by the presence or absence of oscillations uses an integrating circuit in the #A path, the output being zero (i.e. oscillations absent) if a fault develops in any of the components of the circuit. In Fig. 3 the A and B inputs are supplied as oscillations to the bases of transistors 10 and 26 respectively. The A signal is integrated by a long timeconstant RC circuit 40, 4 so that a steady voltage appears on the emitter of transistor 1 which is less negative than the supply 11. Transistor 26 is driven between cut-off and saturation by the B signal and its output is passed via an impedance reducing stage 19 to the base of transistor 1. Both extreme values of the B signal are more negative than the emitter potential of 1 due to the A signal so no signal is passed to the output transistor 33. If the A signal is absent, the emitter of 1 is at the potential of the supply 11 and transistor 1 acts as an amplifier for the B signal. The output transistor 33 is supplied through a capacitor 34 so that faulty D.C. levels in the input stages on transistor I cannot affect the output except by cutting it off altogether. The presence of an oscillatory signal on line 39 can therefore only represent #A.B and cannot be due to faulty operation of the circuit. In a modification (Fig. 5, not shown) the integrated A signal is passed directly to the base of the output transistor (41), to which the B signal is applied also via a capacitor (72) and common-emitter stage (63). If the A signal is present, the base of the output transistor (41) is driven positive and no output is obtained. In the absence of the A signal, the B signal drives the base (41) alternately positive and negative and an oscillatory output is obtained (at 77). As before, any fault in the circuit can only result in an absence of the oscillatory output.

Abstract: 1489329 Recovery of sodium hydroxide values from liquid sodium UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 12 April 1976 [29 May 1975] 14805/76 Heading ClA [Also in Division C7] Liquid sodium or sodium alloys circulating in a system have the impurities Na 2 O and Na hydride removed by depositing the impurities in a cold trap and by heating the trap to react the oxide and hydride to form NaOH, monitoring the hydrogen partial pressure to determine the efficiency of the reaction, and by draining the molten NaOH from the system. Liquid metal is drawn from a circulatory system via pipe 11, through pump 13 to an econimizer 15 wherein the heat of the metal is recovered. The cooled metal feeds through pipe 17 to a cold trap pressure vessel 27, filled with metallic packing material 37 on which the impurities crystallize when the vessel 27 is cooled by blower 39 to say 100-200‹ C. A pressure gauge 30 monitors the hydrogen partial pressure within the tank 27, which may be adjusted as required by either venting or adding hydrogen from supply 65. Tank 27 is also fitted with a drain outlet 31, connected by valve 32 to a second tank 45, which again may be heated or cooled by resistance 53 and blower 55. A level indicator 57 is installed in each 45. In operation, liquid metal withdrawn from the system enters tank 27, passing through economizer 15, to fill the tank, passing outside baffle 35 through packing 37 to the upper tank outlet 19, thence back to the circulatory system, having been cooled to 100-200‹C. in its passage through tank 27, so that the oxide and hydride impurities precipitate out on packing 37. When tank 27 is filled with impurities, it is isolated from the circulatory system by valve 23, and any liquid metal drained via outlet 31 to reservoir 67. The tank 27 is then heated to cause the reaction to occur (temperature of 412-550‹ C.), and the molten NaOH is drained into tank 45. indicator 57 showing when reaction is complete. The partial pressure of hydrogen in tank 27 is then measured to see if excess NaH or NaO is present in tank 27 which may be corrected by altering the H 2  pressure until the level in tank 45 is constant indicating that all the impurities have been removed. The cold trap is then reconnected to the circulatory system for further use.

Patent GB-457139-A (GB)
Title: Improvements in or relating to the recovery of phenols
IPC: C07C37/00
Filed: 1935-05-23
Abstract: Phenols are recovered from oils, tars, and the like by extracting with aqueous ammonia, the density of which has been materially raised by one or more dissolved substances, followed by separation of the ammoniacal liquor from the oil, and removal of the ammonia from the liquor.  Substances specified are the nitrates of lithium, sodium, potassium, ammonium, calcium, and strontium, sodium nitrite, chloride or bromide and calcium chloride.  The formation of a non-volatile residue on distilling the phenols obtained by this process is avoided by stripping the ammonia from the aqueous phenol extract and/or treating the separated phenols with carbon dioxide and removing the solid carbonates.  The most effective concentration of ammonia is 30 per cent or more, and saturated solutions of the salt or salts are preferably used.  The ammonia may be removed by heating, or alternatively by subjecting the liquor to a vacuum or blowing with an inert gas, with or without heating.  By removing the ammonia in stages, the phenols may be fractionated.  The ammonia evolved may be absorbed in stripped liquor from which the phenols have been separated, and the heat of absorption utilized in a heat-exchanger for removing ammonia from a further quantity of ammoniacal phenolic liquor, the whole process being preferably carried out in a continuous manner.  The reaction is preferably carried out at normal temperature to avoid working under pressure, but the latter can be done if desired In an example, a naphtha fraction is washed with three successive washes of an equal volume of sodium nitrate-ammonia solution, the solution separated after each wash, and the three batches of wash liquor heated to drive off the ammonia.
