Charge oil characteristics sensed may be (8), flow rate; (17), refractive index; (18) flash point; (19), viscosity; (20), gravity. Sensing means 8A, 8B, 8C may measure flow rate, means 17A the refractive index of the refined waxy oil. At start up, the charge oil flow rate and extract oil temperature are controlled using signals dependent on predicted values of a process condition characteristic A pred and desired refined oil quality a pred, the predicted A pred and a pred being calculated from charge oil properties and solvent flow rate and passed through switches 186, 166 respectively to computers 160, 162, 185 and summing device 161 for calculation of the control signals.

Abstract: 1,149,557. Aminoalkyldihydroethanoanthracenes. CIBA Ltd. 12 Dec., 1966 [10 Dec., 1965], No. 55554/66. Heading C2C. Novel ethano-anthracenes of the formula where A represents a dimethylamino or diethylamino group and the ethano-anthracene is substituted in the 2- or 3-position by chlorine, and salts thereof, are obtained from a compound of the formula which is substituted in the 2- or 3-position by a Cl atom, and in which X represents a dimethylaminomethyl or diethylaminomethyl group in which at least one of the methylene groups vicinal to the nitrogen atom is replaced by a carbonyl group, by selective reduction of the carbonyl group to a methylene group, for example by means of LiAlH 4  or an analogous amide reducing agent. Alternatively a compound of the second formula above in which X represents a dimethylaminomethyl or diethylaminomethyl group which contains either a hydroxy group in the α-position to the nitrogen atom or a C-N double bond is reduced to convert X into the dimethylaminomethyl or diethylaminomethyl group, for example by means of a metal hydride, such as an alkali metal borohydride, or of catalytically activated hydrogen with catalysts such as platinum oxide and Raney nickel. A further modification comprises reacting the corresponding ethanoanthracene in which the 9-position contains an aminomethyl, methylaminomethyl or ethylaminomethyl group with formaldehyde or acetaldehyde in the presence of a reducing agent. The free bases may be converted to salts, especially to physiologically tolerable salts. A list of suitable acids is given. Intermediates are prepared as follows: A mixture of 2-chloroanthracene, N-methylformamide, POCl 3  and dichlorobenzene is heated to form 2-chloro-anthracene-(9)-aldehyde which is saturated with ethylene and heated in an autoclave, then heated with methylamine, hydrogenated and acidified to form 2 - chloro- 9 - methylaminomethyl - 9: 10 - dihydro - 9: 10- ethano - (1:2) anthracene - hydrochloride. Similarly, using ethylamine in place of methylamine, there is obtained 2-chloro-9-ethylaminomethyl - 9,10 - dihydro - 9,10 - ethano - (1,2)- anthracene which is reacted with acetic anhydride to form the corresponding N-acetyl compound. Pharmaceutical and veterinary compositions, useful as psychotropic, sedative medicaments, comprise a compound of the first formula above in admixture or conjunction with a suitable diluent. The compositions may be in forms suitable for oral or parenteral administration or may be in the form of animal fodder or additives to animal fodder.

In Figs. 4 and 5 (not shown) transistors (Q15 or Q9<SP>1</SP>) detect the emitter-base voltage of the output transistor (Q14 or Q11<SP>1</SP>) and in Figs. 2 or 3 (not shown), transistors (Q10 or Q12) connected to the collectors of the output emitter followers (Q9 or Q11) detect which emitter follower is conducting. Figs. 2-5 and 8 show operational amplifiers suitable for use in the selecting circuit and which provide an indication if the amplifier is cut off by the common feedback as described above. The amplifiers have erect and inverting inputs B, H (Fig. 2) to Darlington type emitter coupled pairs Q1, Q3 and Q2, Q4 diodes being provided to stabilize the operation. The analogue output is provided in Fig. 2 by transistors Q8 and Q9, the amplifier being suitable for use in a minimum level selector.

Title: A method for semiquantitative automatic measurement of colour intensity of turbidity of a liquid solution
IPC: G01N21/59
Filed: 1978-08-29
Abstract: A method of photometric semi- quantitative measurement of colour or turbidity of solutions is suitable for indicating reactions taking place in the solutions which give rise to a colour or turbidity change. The method uses a light beam passing vertically through a sample to make a successive series of absorption measurements upon a number of samples which together form a dilution series and are thus of different colour or turbidity. Each successive measurement is analysed by a computer and expressed as a single digit number from a series 0, 1, 2... representative of the measured absorption values. There may be only two, or up to ten steps in the absorption range. A suggested application is detection of hemolysis inhibition of added erythrocytes by measurement of antistreptolysin titre.
