Title: Improvements in or relating to an arrangement for producing electric signals controlling the typing of typewriter signs defined by coordinates
IPC: H04L17/30
Filed: 1961-07-17
Abstract: 964,109. Electric selective signalling systems. PAILLARD S. A. July 17, 1961 [Aug. 10, 1960], No. 25811/61. Heading G4H. In a typewriter of the kind in which a stylus or jet of ink is moved so as to trace a character on depression of a corresponding key, the movement is controlled by means of one or more of a plurality of voltages having various waveforms, all the waveforms being generated continuously and the appropriate waveforms being selected by the key. Generator G provides continuously fifteen different waveforms which feed units x/A, y/A, x/B, y/B &c. there being a pair of such units for each character to be typed. The units x/A, y/A &c. modify, e.g. by amplification, and if necessary combine the waveforms to produce x and y deflections of the stylus. Upon depression of character key A switch Ak is closed and the signals from x/A, y/A are fed to gate circuits x/I, x/II, y/I, y/II. A unit F produces a signal first on line I and next on line II to open x/I, y/I, and then x/II, y/II (since some characters require two pairs of waveforms in order to be synthesized) each for one cycle of the fundamental frequency from G. At the same time a signal on line III causes unit L to move the stylus into contact with the recording medium, and the character is thus traced thereon.

Filed: 1971-04-19
Abstract: 1285315 Diversity reception system LICENTIA PATENT-VERWALTUNGS-GmbH 19 April 1971 [2 July 1970] 26586/71 Heading H4L A signal combiner for a diversity reception system has the output transistor TK1 &c. for each of the N channels controlled in its collector current according to the respective S/N ratio to vary its amplification, and the output at A derives from the summed signal currents. The total current available for the transistors TK1- TKN is the sum of that supplied by control transistors TS1-TSN (of the same conductivity type) which each receive a control signal such as ST1 derived from the noise level of the respective channel. The currents are adjustable by suitable choice of the Zener diode bias voltages UD, so that the current to be shared by the output transistors is made dependent on the noise levels, so that these transistors may operate at optimum operating conditions without risk of overload of one if all but one signal channel fails.

Abstract: 514,600. Valve circuits. PHOTOSWITCH INC. May 9, 1938, No. 27092/39. Convention date, Sept. 16, 1937. Divided out of 514,528. [Class 40 (v)] In a system, in which a relay M is controlled in accordance with the illumination of a photoelectric cell P through valve T, the valve heater is connected across the supply in series with impedance 7 and the cathode is connected to impedance 7. The apparatus is connected to an alternating supply AB and is arranged so that with the cell dark and the terminal A negative, the anode 31 is positive and the adjustment of slider 3 on potentiometer 7 is such that the potential of cathode 4 is higher than that of grid 6, the potential of which is determined by impedance 1. Under these conditions no current flows through the valve. When the terminal A becomes positive, anode 31 is negative, and the valve is blocked. When the cell is illuminated, the impedance of cell P is reduced so that when plate 31 is positive the control grid 6 becomes more positive than cathode 4 and magnet M is energised. During the negative half cycle the valve is again blocked but sufficient energy is stored in impedance I to hold the magnet M energised during the half cycle and the magnet remains energised so long, as the cell is illuminated. The potential of screen 21 is adjusted to prevent the collection of positive ions on the control grid 6. Embodiments in which the magnet is de-energised when the cell is illuminated and in which amplifier valves are provided directly coupled to the valve T and having their heaters also in series with resistance 7 are also described in the specification.
