Abstract: 1,231,618. Voltage detecting. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. July 31, 1968 [Aug. 1, 1967], No. 36550/68. Heading G1U. Also in Division G4] In an arrangement for determining which of several leads carries a voltage of greatest, magnitude, the leads are connected to the inputs of amplifiers Vl-Vj whose outputs are connected as a diode OR gate (D12, D22 &c. R3) to provide the greatest voltage at a common output SP. Each amplifier has a negative feedback branch between the common output and its input, over an attenuating arrangement (e.g. R14, R12). A second negative feedback path, with the same attenuation factor and containing a diode e.g. D11 poled oppositely to that in the OR gate, is provided for each amplifier. The effect of these feedback paths is that any amplifier which does not receive the highest input voltage delivers an output of inverse polarity related to the difference between its input voltage and the highest voltage. The system is used in association with a character reading system, wherein a character to be identified is scanned by a photo-electric matrix arrangement which is arranged to give an output on one particular line corresponding to the character. Due to imperfections in the system, outputs of different magnitude appear on several lines and the system of the present invention is used to determine which is the largest and thus identify the character. The output lines d 1 , d 2  &c. of the amplifier channels are connected each to one input of trigger circuits S 1 , S 2 , .. Sj, to the other input of each of which an adjustable negative bias Ud is applied. Only the (almost zero) output on the line corresponding to the largest input voltage should trigger its related trigger circuit. However, if other channels are producing signals almost as large, they also may trigger their related circuits. The outputs from all the triggers are applied to a test circuit DP, which delivers a reject signal if it receives more than one input. The largest signal, which appears at SP, is compared with a reference U 2  to trigger a circuit S 2  if it exceeds U 2 . A gate 71 is designed to operate if it receives no output from DP and an output is applied to AND gates GF and GR. When timing pulses are applied GR delivers a pulse to open the gates G 1 -G 2 , so that the line corresponding to the operated trigger S 1 -S 2  may be identified.

Acrylonitrile polymer-pigment concentrates containing 20-80% by weight (based on the total amount of polymer and pigment) of a disazo, quinacridone, phthalocyanine, anthraquinone, pyrazolone or thioindigoid pigment are prepared by forming an intimate suspension of said pigment in a solution of the acrylonitrile polymer, dissolving a base in the suspension in an amount of 1-10% by weight of the pigment, and then contacting the suspension with a non- solvent for the pigment and polymer in order to precipitate the said concentrate, the non- solvent being miscible with the solvent of the acrylonitrile polymer solution. In a preferred embodiment, the suspension is extruded into the non-solvent, whereby the concentrate is obtained in the form of a continuous strand. The concentrates are particularly useful in the preparation of dope-dyed acrylonitrile polymer fibres. The polymer component of the concentrate may be acrylonitrile homopolymer or a copolymer of acrylonitrile with a comonomer such as methyl methacrylate, vinyl chloride or vinyl acetate. Suitable solvents for the acrylonitrile polymer include di- (lower alkyl) sulphoxides and lower alkyl derivatives of acetamide or formamide. The base which is dissolved in the suspension may be, for example, an alkali metal hydroxide or carbonate, ammonia, an alkylamine, an alkanolamine or an alkylenediamine. Examples of suitable non-solvents are water, lower alkanols, ketones, esters and hydrocarbons (aliphatic or aromatic). The concentrate can be used together with other pigments, e.g. carbon black or titanium dioxide, in the preparation of coloured fibres.
