Patent GB-748959-A (GB)
Title: Improvements in the production of alcohols
IPC: C07C29/04
Filed: 1953-07-21
Abstract: Alcohols are produced by reacting an olefine in the gas phase at a raised temperature and superatmospheric pressure with steam using a catalyst on a porous carrier substance, the direction of flow of the reaction mixture over the catalyst being periodically reversed.  The preferred reaction temperatures are in the range 240 DEG  and 320 DEG C. and the preferred pressures are between 20 and 80 atmospheres. Suitable carrier materials for the catalyst are, for example, active carbon, kieselguhr and silicic acid.  The migration of phosphoric acid from the reaction chamber can be prevented by, in addition to reversing the flow of the reactants, arranging in front of, behind and, if desired, between the catalyst, layers of porous substance initially free from phosphoric acid.  In the example ethylene and steam are passed through a catalyst consisting of phosphoric acid supported on silica gel at elevated temperature and pressure, the direction of flow being periodically reversed to give crude alcohol. Specification 651,275 is referred to.

Title: Improvements in or relating to radar display apparatus
Inventor: BOLLARD DAVID ROOKSBY
IPC: G01S13/70
Filed: 1959-07-01
Abstract: 937,846. Analogue calculating. DECCA Ltd. Sept. 30, 1960 [July 1, 1959], No. 20287/59. Class 37. [Also in Group XL (c)] Relates to an automatic tracking system which generates a D.C. voltage representing the predicted co-ordinate position of a moving echo on a pulse radar display and in which said predicted position voltage is periodically corrected by an error voltage representing the difference between the predicted co-ordinate and the actual co-ordinate as determined by the radar. According to the present invention the predicted position voltage is produced as the output from a linear integrating circuit having a feed-back loop with a differentiating circuit therein to form a self-sustaining waveform generator with the output from the integrating circuit varying linearly at a rate maintained constant by the output from the differentiating circuit, a correction voltage derived from the error voltage being applied periodically to reset the signal amplitude in the loop. As shown, the differentiating circuit comprises a high gain amplifier 25 with a feed-back resistor 27 and input capacitor 26 and the integrating circuit comprises a high gain amplifier 22 with a feed-back capacitor 24, the output from the differentiating circuit being applied via a long-time-constant CR network 28, 29 and cathode follower 30 to an input resistor 23 and the error voltage being applied to an input resistor 42 of lower resistance than resistor 23 so that the error signal is integrated much more rapidly than the rate of signal from the differentiating circuit. The initial level of the integrator output is set by applying an initial shift voltage to the integrator 22 via a capacitor 90 and a switch 91 which is ganged to a switch 92 to short out the feed-back resistor 27 in the differentiating circuit. When the apparatus is inoperative the integrator output is returned to a predetermined level by placing the switches 91 and 92 in the initial shift position and then closing a switch 94 to discharge the capacitor 93 through a low resistance 93. The initial rate of change of the integrator output may be set by applying a voltage from a rate potentiometer 95 to the input of the cathode follower 30 and the rate may be subsequently corrected by alternately connecting one plate of a capacitor 98 to the input and output of the cathode follower 30 by means of a switch 99, the other plate of the capacitor 98 being connected to the potentiometer 95.
