Abstract: 926,494. Neutralizing transistor circuits. BLONDER-TONGUE ELECTRONICS. June 12, 1961 [Dec. 19, 1960], No. 21141/61. Class 40 (6). In a transistor circuit, feed-back caused by the internal collector/true-base capacitance Cb<SP>1</SP>e, acting in series with the emitter/true-base capacitance Cb<SP>1</SP>e is neutralized by capacitances C 4 , C 5 connected in series between the collector and emitter, the signal input terminal I, II being connected respectively to the junction of capacitances C 4 , C 5  and to the physical base terminal b of the transistor. For neutralization, the ratio of C 4  to C 5  is made equal to the ratio Cb<SP>1</SP>c to Cb<SP>1</SP>e. External stray capacitance represented by Cbc is neutralized as by inductance L 1 . In the circuit shown, Rbb represent the base spreading resistance and Rb<SP>1</SP>e represents the base to emitter internal resistance and when Rb<SP>1</SP>e cannot be ignored, e.g. at the lower signal frequencies, resistance R 1  is provided to effect compensation. Other stray capacitances, e.g. Cs may be neutralized by slightly detuning L 1 , Cbc. A further resistance R 2  may also be provided in order that the product Cs R 2  should equal the product C 5 R 1 . The stray capacitance Cbc may also be neutralized by C 1  (in parallel with Cs) (Fig. 2, not shown) in which case inductor L 1  is omitted. A pair of stages similar to that shown in Fig. 1 may form a push-pull circuit (Fig. 3, not shown) is the stray capacitance being compensated by cross-connected capacitors. The basic circuit may be re-arranged so that input terminals I or II are earthed (Figs. 4 and 6, not shown) or so that the collector is earthed (Fig. 5, not shown). When input terminal I is earthed, C 4  may be the stray capacitance between collector and earth and C 5  the emitter resistor by-pass capacitance.

The hydrogen chloride may be generated in situ, and preferred solvents are benzene, chloroform and dioxan. The starting materials are prepared by selective ethynylation of the 3,17-diones and this accounts for their presence in them.  After the 5a -chloro-compound has been separated the 3,17-diones remaining in solution can be recycled to the ethynylation step.  In a modification of the above process the required product is separated from reaction mixtures obtained by the Oppenauer oxidation of 17a -ethynyl-19-nor - D 5(10) - androsten - 3b ,17b  - diol, such mixtures comprising the unreacted starting material, and the corresponding 3-one and 3,17-dione and their D 4-isomers, by acylating to give the 3-acylate of the starting material, and then using the resulting mixture as the starting material in the hydrochlorination step.

Abstract: In the Fischer Tropsch synthesis using an iron catalyst obtained by precipitation by an alkali metal compound, and containing as a result of incomplete washing out, 3-20 per cent of alkali metal calculated as potassium monoxide, of the iron present, calculated as metallic iron, a synthesis gas rich in carbon monoxide is employed to offset the excessive carbon monoxide consumption consequent upon the high alkali content of the iron catalyst.  The product has a high content of oxygenated compounds, in an example 30-40 per cent, mainly alcohols.ALSO:Iron catalysts for Fischer Tropsh synthesis, prepared by precipitation from aqueous salt solutions by an alkali metal, are incompletely washed so as to leave 3-20 per cent of alkali metal compond calculated as potassium monoxide, of the iron present calculated as metallic iron.  Further quantities of alkali metal compounds may be added subsequently.  The precipitation may be effected in the presence of small quantities of compounds of copper, zinc, calcium, vanadium, cerium, tungsten and of the elements in the fourth to seventh groups of the periodic system. An example relates to an iron catalyst containing copper and calcium precipitated by sodium carbonate in the presence of kieselguhr from a solution of the nitrates and washed so as to leave an alkali metal content calculated as potassium monoxide of 8 parts per 100 parts of iron.  The filter cake is dried and reduced at 300 DEG C.
