Abstract: 729,242. Inks. NATIONAL CASH REGISTER CO. Oct. 15, 1952 [Oct. 20, 1951], No. 25849/52. Class 146(3). [Also in Group XVI] Printing, writing, or marking fluids adapted to assume different colors when applied to suitably sensitised surfaces comprise a colorless fluid containing two different organic adsorbate substances both of which give a coloration on adsorption contact with one kind of inorganic absorbent substance whereas only one thereof gives a coloration with another kind of inorganic adsorbent substance. The record surface may be partly sensitised with an inorganic adsorbent substance sensitive to one of the adsorbate substances while the remainder of the surface is sensitised with an adsorbent sensitive to both the adsorbates and the marking fluid is applied selectively to either portion of the record material. Adsorbate compounds specified are malachite green lactone, N-p-nitrophenyl rhodamine B lactam, and 3, 3-bis-(p-ethylaminophenyl) phthalide while the preferred record material sensitising adsorbent substance is attapulgus clay which may be applied to paper by coating processes normal to the paper coating industry ; calcium silicate may also be used. In use with account forms the portions thereof corresponding with columns can be sensitised with different adsorbents and thus on application of the marking fluid the entries in the respective columns will appear in different colours. The adsorbate compounds are applied in solvents e.g. chlorinated diphenyl or toluene. When a marking fluid containing a mixture of malachite green lactone and N-p-nitrophenyl rhodamine B lactam is used in conjunction with attapulgus clay, which is color sensitive to both these compounds, a purplish lavender color is obtained which is the resultant of the red and blue-green colors produced by the indi. vidual compounds ; when calcium silicate is used as adsorbent the lactam compound is not changed to colored form and the resultant color is the blue-green obtained from the lactone. Specification 666,450 is referred to.

Title: Voltage-to-digital converter

Filed: 1974-06-11
Abstract: 1436852 Analogue to digital converter GENERAL ELECTRIC CO 11 June 1974 [11 June 1973 27 July 1973] 25947/74 Addition to 1436851 Heading H3H In an analogue to digital converter including a voltage to frequency converter and a phase detector operating in a phase locked loop and generating a time duration signal proportional to the unknown input voltage, a two level control signal connects either the unknown voltage or a reference voltage to the converter input and switches a counter which counts clock pulses during the duration signal to count down when the reference voltage is applied and up when the unknown voltage is applied. Preferably, after changing the input, the phase locked loop is allowed to settle before the count is made. The reference is preferably zero volts. The control logic 48 initially sets switch 42 to terminal 43. Zero reference voltage is supplied via resistor 12, and combined with a (fed back via resistor 28) at 45. The combined voltages are filtered and drive voltage controlled oscillator 14. The oscillator output is squared and divided by counter 14 and compared in the phase detector 18 with the output of oscillator 20 divided by counter 22. The phase detector output is a train of mark/space signals with the mark duration related to input voltage. When the loop has been allowed to settle, clock pulses from oscillator 20 are fed to the down input of the counter 30 for the duration of one mark pulse. The control logic then moves switch 42 to 41 connected unknown voltage V x  to the input and, after the settling period. The clock pulses are fed to the up input of the counter. The resulting count represents the difference between V x  and the reference voltage and is transferred to holding register 32 for display.
Patent GB-407935-A (GB)
Title: Improvements in or connected with variable reactances and circuits including variable reactance
IPC: H03C1/52
Filed: 1934-09-19
Abstract: 407,935. Valve modulating circuits. DEHN, F. B., 103, Kingsway, London.- (Elwell, C. F., and Terman, F. E. ; Stanford University, California, U.S.A.) Sept. 19, 1932, No. 26057. [Class 40 (v).] The input reactance of a thermionic valve is varied in a cyclic manner by imposing similar variations on a positive or negative resistance connected in its plate circuit. The resistance may take the forms described in Specifications 407,933 and 407,934 and it may be varied at a carrier frequency. If a modulating frequency is applied to the valve input, side-frequencies without the carrier may be picked up from the input circuit. Fig. 1 shows the principle of the invention, the grid and plate of a valve 5 being coupled by a condenser 7, and the plate voltage being applied through a choke 10. The variable resistance 11 is connected across the plate and filament in series with a blocking condenser 12. As the resistance 11 varies, the effective input reactance between the terminals 1, 2 is varied ; and if a signal voltage is applied at the terminals 1, 2 and the resistance 11 is varied cyclically at carrier frequency, side-bands or side-frequencies will be produced in the input circuit. In Fig. 2, the grid and anode of the valve 5<1> are connected by an inductance 15 in series with a condenser 16. The variable resistance in the plate circuit of valve 5<1> comprises the plate-filament path of a dynatron valve 17. This valve has an outer grid 22 maintained positive by connexion to a battery 8<1>, and the plate voltage has a mean zero valve maintained by the coil 19. The carrier wave is applied to its control grid 25, thus varying the slope-resistance of the plate-filament path, and so varying the reactance across the terminals 1<1>, 2<1>. A block condenser 20 may be connected between the plates of the valves 5<1>, 17, or they may be directly connected so as to operate at the same battery voltage. The specification states that if the dynatron is adjusted to give a negative resistance in its plate-filament path, then the reactance at the terminals 1<1>, 2<1> will be negative, and will be either inductive or capacitative according as the coupling between the grid and plate of the valve 5<1> is predominantly inductive or capacitative. These negative reactances may be such as to balance any positive reactance in the input circuit, and thus give the input circuit zero reactance over a range of frequencies.
