Title: Content addressed memories
IPC: G11C15/04
Filed: 1966-07-22
Abstract: 1,119,440. Associative stores. RADIO CORPORATION OF AMERICA. 22 July, 1966 [3 Nov., 1965], No. 33062/66. Heading G4C. In an associative store, a control word is derived from the comparison of the tag word and each stored word, control word bits of one value representing stored bits which do not correspond in value to applied tag bits, those control words having a non-zero predetermined number of bits of the one value causing readout of the corresponding stored words in turn. Each tag bit is a marking on one of two lines to represent 1 or 0, or on neither line to represent " don't care ". The two lines are ANDed with the inverse and true outputs respectively of a corresponding storage flip-flop in each storage word location, the two AND gates feeding an OR gate which thus produces a 1 only if the tag and stored bits are unequal and the tag position is not a " don't care " position. For each storage word location separately, logic circuitry responds to the OR gates to detect whether (only) 0, 1, 2, 3, 4 bit positions differ (between tag and stored bits) producing corresponding signals if so. The 0 signal will set a marker flip-flop corresponding to the storage word location, as will any one of the 1, 2, 3, 4 signals, if selected for this purpose at a respective AND gate. The storage words having their marker flip-flops set are read-out and the marker flip-flops reset in turn. Data is initially read-in via the tag lines after locating an empty word location by matching on an all-zeros tag. In a modification, the bits from the OR gates above, representing the results of the bit comparisons, are entered into a shift register, and the 1s shifted along to overwrite the 0s. The shift register and AND gates connected to it then produce the 0, 1, 2, 3, 4 signals.

Title: Remote control for digitally tuned resonant circuits
IPC: H03J1/18
Filed: 1962-08-31
Abstract: 1,006,330. Electric selective signalling. GENERAL DYNAMICS CORPORATION. Aug. 31, 1962 [Nov. 16, 1961], No. 33528/62. Heading G4H. In a remote control system, a plurality of output shafts are rotated via individual clutch means by a common motor, energization of each clutch means being via a circuit in a corresponding open-seeking servo having an encoding switch and a decoding switch, the latter being rotatable with the output shaft, and each circuit feeds a common OR gate to control energization of the motor. Fig. 3 shows one servo, five of which are provided (having the motor in common) to act five output shafts (local tuning shafts) in angular positions corresponding to those of five remote tuning knobs, the five shafts selecting capacitors and inductors in a resonant tank circuit to set the frequency of a radio, each shaft being responsible for one decimal order. Fig. 3 shows two complementary coded-gap wafer switches 50, 60, the first on the shaft of the knob and the second on the output shaft. If the positions of the switches 50, 60 do not correspond, current flows through the switches 50, 60 and at least one of four signalling wires linking them, to energize a clutch 39 so that the output shaft is driven from the motor. The motor is energized via a normally-open switch controlled by a relay coil which is energized by a five-input OR-gate (diodes) as long as at least one of the clutches 39 is energized, one of the OR-gate inputs being connected in parallel with each clutch 39. Two further complementary wafer switches are provided in Fig. 3 to enable the output shaft to go between any two of its ten positions. Fig. 5 shows a modification suitable for use when the output shafts cannot be rotated indefinitely in one direction. Mechanical stops 7b for the output shafts (e.g. 17) are provided. When the output shaft reaches position 9 or position 0, a wiper 100 driven by the output shaft de-energizes clutch 39. Wipers 110, 111 are provided on the shaft of the motor 34 so that when the latter reaches position 0 or 9, one of relays 104, 105 is energized and relay 117 is energized or de-energized, to reverse motor 34 and complete a circuit shunting wiper 100 to allow clutch 39 to be energized. The motor 34 thus turns back and forth until all the output shafts are in the required positions, when the OR gate 90 ceases to provide an output thus stopping the motor 34. Fig. 6 (not shown) shows a modification in which, after all the output shafts have been properly set, the motor 34 continues running until it reaches position 9: this is achieved by connecting an extra input of OR gate 90 to the mutually-connected contacts 0-8 of wiper 110. Fig. 7 (not shown) shows a similar modification in which motor 34 will stop at either position 9 or position 0: this is achieved by connecting the extra input of OR gate 90 instead to the mutually-connected contacts 1-8 of an extra wiper on the motor shaft.
