Title: Negative resistance logic logic circuit reset system
IPC: B22C21/00
Filed: 1961-08-16
Abstract: 963,600. Tunnel diode logic circuits. RADIO CORPORATION OF AMERICA. Aug. 16, 1961 [Sept. 14, 1960], No. 29641/61. Heading H3T. Resetting of a tunnel or like diode logic circuit is effected by changing the state of a further negative resistance diode which thus applies a reset voltage through a coupling diode to the logic circuit. A germanium tunnel diode 12 which may be switched from its normal voltage state to the other state by logic signals applied to point 20, is reset by a reset wave applied to terminal 38. During the positive-going part of a reset wave a silicon diode 46 is non-conductive but during the negative-going part a gallium arsenide tunnel diode 60 switches to its high voltage condition causing the diode 46 to be rendered conducting and so reset the tunnel diode 12. The tunnel diode 60 will return to its low voltage state after a time determined by inductor 62 or, where the inductor is omitted, at the end of the reset pulse. The reset wave may be obtained from a further logic circuit when the logic operation has been completed or from a sine wave " clock " source, in which case the diode 60 is located close to the logic element. A single tunnel diode 60 may serve a block of logic elements which may be coupled together through backward diodes (Fig. 1, not shown).

Title: Semi-conductor direct current stabilization circuit
IPC: H03F1/44
Filed: 1953-10-28
Abstract: 743,824. Transistor amplifying circuits. RADIO CORPORATION OF AMERICA. Oct. 28, 1953 [Nov. 15, 1952], No. 29834/53. Class 40 (6). In an earthed emitter circuit an impedance capable of passing D.C. is coupled between the collector and the base to stabilize the operation of the circuit with semi-conductor devices having various characteristics. A signal from source 15, Fig. 1, is applied to the base 12 of a transistor with grounded emitter 13 and collector 14 having a feed resistor 19 and output load 21. The base is connected over a stabilizing resistor 23 so that when a transistor is substituted needing a greater collector current, the collector voltage would become more negative, carrying the base voltage more negative. The fall in base voltage increases the base current and hence the collector current which stabilizes at a new value. In a modification, Fig. 2, further stabilization is provided by resistor 33, by-passed at signal frequencies by a capacitor 34, the current through resistor 23 being increased by resistor 35. The collector feeds over coupling capacitor 20 the base of a second transistor 36 with D.C. stabilization over resistors 44, 45. In order to prevent degeneration, the junction is held at earth potential for signal frequencies over capacitor 46. In an R.F. or I.F. amplifier, Fig. 3, the coupling from collector 50 to base 56 is over series circuit 54, 55, degeneration through resistor 23 being at a minimum at the resonant frequency when no appreciable signal voltage appears at the collector. An inductor 65 is arranged in series with resistor 66 to present a high impedance at signal frequency and thus reduce degeneration.

Title: Process for the manufacture of tetrakisazodyestuffs containing copper
IPC: C09B45/01
Filed: 1936-11-07
Abstract: Azo dyes, copper compounds of.-Tetrakisazo dyestuffs containing copper are obtained by treating dyestuffs of the general formula <FORM:0484597/IV/1> (wherein R1 represents the residue of an initial diazo component, R2 and R3 represent residues of amines of the naphthalene series coupled in p-position to the amino group, R4 represents the residue of a component coupled in o-position to a hydroxy group and Hal represents a halogen atom), which dyestuff contains at least 3 solubilizing groups, with an agent yielding copper in a caustic alkaline medium at an elevated temperature until, with substitution of Hal by hydroxy, the copper complex compound of the corresponding o : o1-dihydroxyazo dyestuff is formed.  The products give grey dyeings, very fast to light, on fibres of natural or regenerated cellulose.  In examples, (1) the sodium salt of the dyestuff, aniline-2 : 5-disulphonic acid --> 1 - 7-aminonaphthalenesulphonic acid --> 1 : 7-aminonaphthalenesulphonic acid --> 1-chloro-2 : 5 : 7 - aminonaphtholsulphonic acid --> 2-naphthol, is heated for 4 hours at 85-90 DEG  C. in an aqueous solution containing copper sulphate, glycerol and caustic soda; the product, obtained by salting out, dyes cotton greenish grey from a Glauber saltsodium carbonate bath; the first component may be replaced by aniline-2 : 4- or 3 : 5-di-sulphonic acid or 4- or 5-sulpho-2-aminobenzoic acid and either the second or the third component by 1-aminonaphthalene; alternatively, the first component may be replaced by aniline-3-sulphonic acid and the end component by 1 : 4- or 2 : 6-naphtholsulphonic acid; (2) the sodium salt of the dyestuff, 2-aminonaphthalene-5 : 7-disulphonic acid --> 1-aminonaphthalene --> 1-aminonaphthalene-7-sulphonic acid --> 1-chloro2 : 5 : 7 - aminonaphtholsulphonic acid --> 2-naphthol is converted into a copper complex compound as in (1); the product dyes cellulose fibres reddish grey.  The glycerol in these examples may be replaced by other agents yielding soluble compounds with cupric hydroxide in an alkaline medium, e.g. tartrates.  In the case of difficultly soluble dyestuffs, coppering is advantageously effected in presence of a solvent such as pyridine.  In some cases an alkali metal salt is added to keep the dyestuff partly out of solution.
