Abstract: 1470774 Electric analogue calculating FOXBORO-YOXALL Ltd 2 July 1974 [27 June 1973] 30598/73 Heading G4G An electric analogue circuit for calculating D=A.B/C comprises an operational amplifier integrator circuit A1, 4 which receives through resistor R A  a continuous input signal representing A and through resistor R B  an input signal representing C only when f.e.t. 3 is conducting, the A and C signals being of opposite polarities and C being greater than A so that the integrator output will ramp in opposite directions depending on whether f.e.t. 3 is on or off. A comparator A3 detects when the integral of A alone reaches a reference level determined by a resistor 5 and causes a pulse circuit A4 to deliver a pulse of fixed duration to turn on f.e.t. 3 for such duration to integrate A and C in A1, A4. It is shown that the ratio pulse duration/repetition time on line 10 represents A/C and this line is connected to the gate of f.e.t. 11 allowing a signal representing B to be integrated in integrator A2, A13, R D  whose output represents D=A.B/C. Further final integrators may be provided to multiply other signals by the same ratio A/C, Fig. 3 (not shown) and also by having A=B squares can be calculated and other powers and roots can also be derived by apparatus including the above circuit. In practice, a f.e.t. (7) Fig. 2 (not shown) is interposed between A3 and A4 with its gate connected to line 6 to prevent A3 from switching off circuit A4 until the pulse on line 3 is completed.

Abstract: 244,275. Mond, A. L., (American Shale Reduction Co.). Dec. 22, 1924. Hydrocarbons, cracking.-In distilling oil shale, bituminous coal, lignite, &c. to obtain light oils, the shale &c. is preheated to a temperature just below that at which volatile substances are evolved, and is then suddenly heated to a temperature at which the whole of the volatile substances are driven off. The vapours are condensed fractionally. The material, fed through a counterweighted valve 2 and by a conveyer 4 passed down an inclined rotary retort 5 in which it becomes heated to about 750‹ F.. and falls into an enlarged end chamber 6 provided with a jacket 10 containing molten metal, in which it is heated to about 1000-1100‹ F. The spent shale &c. is discharged through a valve 18. The vapours generated in the chamber 6 become hydrogenated by the action of steam from the shale in the presence of the spent shale. The vapours are drawn by a pump 31 through baffled chambers 22, 28 maintained at temperatures of about 740‹ F. and 620‹ F. respectively by the heat of the furnace gases and controlled by thermostatic devices which regulate entry of cold air through passages 25. Wax, pitch, &c. are deposited in chamber 22 and lubricating oil in chamber 28. Gasoline is separated from the vapours in a condenser 32, and the uncondensed gases may be used for heating the retort. In a modified form, the chamber 6 contains a drum closed at both ends, which leaves only a narrow annular passage in which a more intimate contact betwen the shale and the vapours is obtained.
