Title: Capacitive read only memory
IPC: G11C17/04
Filed: 1973-06-12
Abstract: 1400889 Read only memories; code converters BURROUGHS CORP 12 June 1973 [26 June 1972] 27864/73 Headings G4A and G4H A decoder, or read only memory, is so arranged that a respective one of a number of outputs 48 is energized in response to the application of a corresponding parallel n-bit signal to work lines W1-Wn, Fig. 3. Each word line, e.g. W1 is connected directly to a first AND gate, e.g. 32. Each gate feeds a respective sub-word line capacitively coupled to certain of a number of sense lines S1-Sn. The capacitors are so arranged that for any one combination of pulses on W1-Wn all of the sense lines except one are pulsed: for example, if only W1 and Wn are pulsed only S2 will not be pulsed. The sense lines feed inverters 44 feeding bi-stables 46, and consequently only one bi-stable will be set in response to the signal on W1-Wn. The AND gates are enabled by pulses T1 and the bistables are triggered by pulses T2. The output of each bi-stable may be gated by pulses T3 to a second capacitor decoder matrix, Fig. 4 (not shown), which converts the one-outof-n output to a parallel-bit output.

Title: Improvements in or relating to electric signalling systems
IPC: G01F23/44
Filed: 1930-09-18
Abstract: 363,408. Electric signalling systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, and GUNNING, P. F., 10, Fairfield Street, Fairfield, both in Liverpool. Sept. 18, 1930, No. 27955. [Class 40 (i).] In a system for repeating at a remote station the movements of a meter pointer &c., impulses are transmitted corresponding in number to the extent of movement and consist of interruptions or reversals of a steady current according to the direction of movement. The steady current normally flows over the connecting line to indicate the satisfactory condition of the line. The Figure shows a system for the remote indication of the water-level in a reservoir. An impulse wheel 10, driven by a float, alternately operates relays N, M, which being slow to release provide an overlap period during which relay PU is energized. Normally, polarized relay H at the receiving station is energized and in consequence relays Q, C are operated. Relay C illuminates line supervising lamp LP and prepares the stepping magnet DM1 of the receiver LI. When the impulse wheel rotates anticlockwise, relay PU operates intermittently and relays H, Q pulse accordingly to operate the magnet DM1 and step the indicator LI through the appropriate distant. Throughout impulsing, slow-release relay C main. tains the lamp LP operated. When the impulse wheel rotates clockwise, a lever is operated through a friction clutch to close the contacts CS and thereby provide for reversals of current over the line instead of interruptions during the impulsing of relay PU. Current reversals impulse relay P which operates the reverse stepping magnet DM2. Relay Q remains operated throughout impulsing due to the overlap and operation of relays P, H.

Title: Improvements in and relating to impedance matching indicators
IPC: H03H7/38
Filed: 1947-10-20
Abstract: 633,975. Measuring bridges. GENERAL ELECTRIC CO., Ltd., and ROSENBROCK, H. H. Oct. 20, 1947, No. 27996. [Class 37] The output circuit of a source such as a transmitter 10 is coupled through a feeder 12 and matching circuit 13 to a load such as an aerial 11. Circuit 13 includes a bridge composed of an inductor 17, resistance 18, inductor 19 and the input circuit of an auto-transformer 20. A milliammeter 21 is connected across one diagonal of the bridge, and the feeder 12 is connected across the other diagonal. The bridge is arranged to be balanced when the input impedance of transformer 20 is resistive and equal to the characteristic impedance of feeder 12. Any departure from the matched condition will give a deflection on milliammeter 21. As elements 17, 18 are in shunt to feeder 12 they are given high values. Inductor 19 is in series with feeder 12 and its effect is reduced by winding it in an opposed sense to winding 17 on a common dust core 22. This increases the sensitivity of the bridge. By including some reactance in element 18, it is possible to match a corresponding reactance in the load. To reduce power losses the resistance of 18 is made as large as is consistent with maintaining a satisfactory out - of - balance current through meter 21.
