Title: Improvements relating to the recovery of pure phenol from crude phenol
IPC: C07C39/04
Filed: 1956-07-10
Abstract: Crude phenol obtained by oxidation of cumene by way of cumene hydroperoxide is purified by passing it over a dehydration contact at 200-400 C., in order to convert hydroxyl containing compounds, present in the crude phenol into decomposition products boiling below the boiling point of phenol, and separating said decomposition products from phenol by fractional distillation. Suitable dehydration contacts are activated aluminium oxide, activated bleaching earth and phosphoric acids.  The bleaching earths are preferably activated by means of hydrochloric acid before use, and a suitable phosphoric acid contact may be prepared by applying orthophosphoric or polyphosphoric acid to a carrier such as activated carbon or infusorial earth.  The treatment of the crude phenol may be carried out batchwise or continuously. If the reaction is carried out continuously the dehydration step is preferably carried out in a reaction vessel arranged in advance of and connected with a distilling column for continuously separating pure phenol from the crude product. Substances formed by dehydration such as water, mesityl oxide and a -methylstyrene, and a small amount of phenol can be discharged as the head product, while the pure phenol is discharged laterally at a suitable point of the column.  In the batchwise process the crude phenol which has been separated from the acetone, cumene and a -methyl styrene is dehydrated, and then subjected to fractional distillation.  Examples are given using dehydration contacts of Al2O3 precipitated on infusorial earth, bleaching earth and phosphoric acid precipitated on granulated active carbon.  Specification 745,343 is referred to.

Title: System of remote control
IPC: B62D1/28
Filed: 1943-12-30
Abstract: 593,572. Remote control. SKILLMAN, T. S. Dec. 30, 1943, No. 21876. Convention date, Dec. 10, 1942. [Class 40 (i)] In a system in which control is exercised by varying the frequency of a transmitted current, currents derived by beating the received signals with the output of a local oscillator tuned in accordance with the position of the controlled object are passed in parallel to high- and lowpass filters having the same cut-off frequency and to a filter tuned sharply to the same frequency and a servomotor is controlled by relays operated respectively by the outputs of these filters to keep the beat frequency equal to the filter frequency. Preferably, the resistance of the remote apparatus to control is felt by the operator. As shown, the control wheel 7, Fig. 1, adjusts a condenser 11 to vary the frequency of a generator 38, Figs. 5 and 6, the output of which is heterodyned at the receiving end and passed to filters 54 ... 56 having the characteristics shown above them in the drawing. When the positions of the control wheel and the controlled shaft 25, Fig. 2, are in agreement, the resultant frequency is that of filter 55 and relay 60 disconnects the armature of a servomotor 35 geared to shaft 25. At other times, either 61 or 62 is operated to connect up one or other of two field windings 65, 66 and energize a relay 67 to connect up the armature. The motor then drives the shaft which adjusts the frequency of the heterodyne oscillator until the beat frequency is the frequency of filter 55. Shaft 25 is coupled to the controlled object through a resilient connection 28 and the amount of " give " determines the frequency of a reverting signal generator, the output of which is led to filters 72, 73 at the sending end with the characteristics indicated on the drawing. The extent to which this frequency differs from a standard frequency determines the degree of energization of one or other of two clutch magnets 21, 22 which control friction wheels tending to drive the control wheel in one direction or the other. The tendency to rotate is resisted by a brake 13. The servomotor 35 can be hydraulic or electric and the reverting control on the wheel 7 may be exercised by solenoids acting directly or by hydraulic means. The devices shown for responding to the variable frequency signals at the receiving end may be used at the sending end and vice versa.
