Title: A random signal generator
Inventor: TAIT DAVID ADAMS GILMOUR
IPC: H03K3/84
Filed: 1963-06-05
Abstract: 1,071,154. Random pulse generators. SOLARTRON ELECTRONIC GROUP Ltd. Sept. 3, 1964 [June 5, 1963], No. 22435/63. Heading G4D. [Also in Division H3] In a signal generator noise signals are applied to a plurality of bi-stable circuits which are gated periodically so as to be set in one state or the other in dependence upon the polarity of the random noise signals, with the result that in operation a random combination of states of the bi-stable circuits is set up the outputs of which produce when summed, a signal whose level is a random one of a finite number of possible levels. Random noise signals, Fig. 1, are passed from primary noise sources 10, 24 to 29, to a plurality of random square pulse generators 14 which produce at their outputs when gating signals at a frequency determined by generator 15 are applied to gate 11 a signal of predetermined magnitude when bi-stable circuit 12 is in one state when polarity of the noise signal is one sign and no signal when circuit 12 is in its opposite state when the polarity of the noise signal is the opposite sign. Each square pulse generator 13, 34 to 39 thus produces a train of square pulses of constant magnitude, the presence of a pulse in each gating period being determined on a random basis. The combined currents are alternately fed over changeover switch 30 to capacitors 31, 32, and to amplifier 40 over switch 33. The switches 30, 33 are controlled by driver circuit 42 to change at the lowest frequency of generator 15 and divider chain 16 so that after a number of gating signals the switches are changed to allow one of the capacitors to discharge through 40 to provide an output voltage proportional to the sum of the random binary levels and the other capacitor to be charged by the random pulses. In the arrangement of Fig. 5 and Fig. 4 (not shown), the output from a broadband noise source 50 is applied through a set of gating circuits opened sequentially by ring counters 58, 59 forming part of a control pulse source 54 to first and second adders 52, 53 in alternate gating periods. The control pulse source 54 also opens gates 55, 56 in alternate integrating intervals so that during one interval in which an output from adder 52 is provided through gate 55 the adder receives in each of the gating periods a random binary number. At the end of this integration interval the adder 52 is cleared, the gate 55 is closed, the gate 56 is opened and the noise signals are applied through the gating circuits 51 to the adder 52. In the arrangement of Fig. 6 (not shown), one of the adders is omitted and the output from the remaining adder is passed via a multiway switch and gate to a staticizer or register.

Filed: 1933-08-17
Abstract: 422,285. Electromagnetic interrupters. GREENHAM, C. H., 209B, Great Portland Street, London. Aug. 17, 1933, No. 22968. [Class 38 (v)] A device for controlling therapeutic electric current of the type which includes a pendulum operated by a solenoid and a variable resistor actuated by the pendulum and included in the electrotherapeutic circuit has an interrupter in the solenoid circuit controlled by means of a wiper mounted for movement with and with respect to the pendulum and adapted to engage a spring switch blade to close the solenoid circuit once in each vibration. As shown in Figs. 2 and 3 the device comprises a pendulum 1 on which is secured a pivoted insulating block 2, the pendulum carrying at its lower end a solenoid 7 adapted to move over curved cores 7. The interrupter mechanism for the solenoid 7 consists of a contact blade 14, normally resting against a fixed stop 17 and carrying a U-shaped block 19. The pendulum carries a switch-actuating wiper arm 12 pivoted on a horizontally-extending arm of a bracket 11, a spring 13 pressing the arm 12 against a shoulder of the bracket so that it tends to remain in any set position. The motion of the depending arm 12 is arrested by stops 20, 21 so that at the end of a swing of the pendulum it is set at an angle to the pendulum axis. In the succeeding swing it clears the opposite projection of the member 19 and engages the opposite stop 20 or 21. Thus, after the pendulum has passed the mid-position consequent downward movement of the arm 12 due to its engagement with the stop depresses adjacent projection of the bracket 19 and carries the switch arm against the contact 18 so momentarily closing the circuit of solenoid 7. A reverse movement occurs in the following swing and the oscillation of the pendulum is maintained by attraction of the solenoid to alternate fixed cores 10. The rate of oscillation may be varied by adjustment of a balance weight 22. The pendulum carries a balanced arm 24 from the upper end of which depends a pivoted dipper rod 25 which is alternately raised and lowered into a container 26 containing resistance liquid in the therapeutic circuit. Interruption and /or reversal of the therapeutic current may take place at contacts 31 the movable pairs of which are carried by blades engaged by an insulating roller 27 mounted on a crank-arm 23 secured to the oscillating pendulum.

Filed: 1958-07-17
Abstract: The invention comprises metallized azo dyes of formula: <FORM:0864276/IV(c)/1> wherein R is the residue of an amino-naphthalene coupling component in which the nitrogen atoms are in o-position to one another.  R1 is the radical of an azo component which may contain further azo groups having the -O-Me-group in o-position to the azo group, Me is copper, chromium, manganese, iron, cobalt or nickel, n is 1 or 2 and the group <FORM:0864276/IV(c)/2> is an azo or azoxy group, in admixture with the corresponding symmetrical dyestuffs.  The copper complexes of the dyestuff mixture may be prepared by reductive linkage, to form an azo or azoxy group, of a nitrotriazole compound prepared by coupling a diazotized 2-amino-6-nitro-naphthalene-sulphonic acid with an o-coupling naphthylamine and then triazolizing, and a nitroazo dye prepared by coupling a diazotized 2-amino-6-nitronaphthalene-sulphonic acid with an azo component coupling ortho to a hydroxyl group and subsequent oxidizing coppering.  The triazolation and/or oxidizing coppering steps may be carried out at the end of the process.  The copper complex may be demetallized and the other metal complexes formed by treating the dyestuff mixture with suitable metallizing agents in substance or on the fibre.  The dyestuffs give green shades on cellulose fibres.  In an example an equimolar mixture of the triazolation product of 2-amino-6-nitro-naphthalene -4 : 8-disulphonic acid --> 2-amino-naphthalene-6-sulphonic acid (I) and the copper complex obtained by the oxidizing coppering of 2-amino-6-nitronaphthalene-4 : 8-disulphonic acid --> 2-naphthol-3 : 6-disulphonic acid (II) is reduced using glucose and aqueous sodium hydroxide solution.  In further examples the azo component of (I) is 2-aminonaphthalene-5-mono- or -3 : 6-disulphonic acid or 1-aminonaphthalene-4-sulphonic acid and the azo component of (II) is 1-chloro- 2-acetylamino- 5-naphthol- 7-sulphonic acid, 1-naphthol- 4-sulphonic acid, phenol- 4-sulphonic acid, 1-(41 : 81-disulphonaphthyl-(21))-3-methyl- 5-pyrazolone and 1-chloro- 2-amino-5-naphthol- 7-sulphonic acid --> 2-naphthol-3 : 6-disulphonic acid.
