Abstract: 1,232,000. Transistor bi-stable circuit. INTERNATIONAL BUSINESS MACHINES CORP. 6 Nov., 1969 [5 Dec., 1968], No. 54366/69. Heading H3T. A cross-coupled bi-stable pair of the semiconductor devices such as F.E.T.'s Q1, Q2 are connected through loads Q3, Q4 to a supply source of a first voltage level V1, and are connected through further semi-conductor devices Q5, Q6 to interrogate and sense lines 16 and 12, 14, the latter being raised in voltage above the first voltage level V1 when the bi-stable is interrogated by a pulse at 16, in order not to destroy the information in the bi-stable. The voltage V1 is sufficient to maintain a given state of the bi-stable, but is not itself high enough to provide non-destructive read-out. To read, Q5 and Q6 both conduct due to the read pulse at 16, and current flows into the bi-stable from the lines 12, 14 on of the latter carrying a greater current than the other according to which of Q1, Q2 is on. A differential amplifier (not shown) senses the difference between the currents in the lines 12, 14 to indicate the bi-stable state. To write, Q5 and Q6 are again turned on, and the potential of one of the lines 12, 14 is lowered to set the bi-stable. A matrix of bistables is mentioned (Fig. 3, not shown).

Abstract: 1,232,261. Vehicle identification. "FOKGYEM" FINOMMECKANIKAI ES ELEKTRONIKUS MUSZERGYARTO KTSZ. 10 May, 1968 [10 May, 1967], No. 22423/68. Heading B7N. In a rail vehicle identification system in which a vehicle number defined by the position of a plurality of permanent magnets in a row and column array B, which is disposed in a horizontal plane below the vehicle A, is read by a similar array C of magnetically operated reed switches disposed between the rails and in which the switch signals are re-coded in a matrix E before application to a store F from which the information is fed to a tape punch unit L, the system is arranged to read the information when the vehicle is disposed in either position on the track. The 12-digit vehicle number is decimal coded in an array of 12 columns and 10 rows of magnet positions and is read by the array of switches 20 when a further magnet on the vehicle operates, in dependence on the disposition of the vehicle, either switch K1 or K2. Assuming the significant digit columns correspond switch K2 is operated to apply a positive signal to the switch array so that if the highest significant digit is, e.g. 2 then a positive signal is obtained at output terminal 102 of row 12<SP>1</SP>. A re-coding diode matrix is associated with each column, e.g. matrix 1211 with switch array column 12<SP>1</SP> and when a positive signal is applied to one of its inputs, e.g. input 102<SP>1</SP> then the number coded in a 5-unit ABC code appears at output terminals 121-125 and this number is, in this case, stored in a five element store associated with the highest significant figure. If the vehicle is disposed in its other position switch K1 is operated to supply a negative voltage to the switch array and, e.g. switch column 12<SP>1</SP> now reads the complement of the lowest significant figure. This information is now re-coded by the five lower rows of the matrix which supply the number in five unit code to the output terminals 121<SP>1</SP>- 125<SP>1</SP> from which it is transferred to the five element store associated with the lowest significant number. In turn the twelve five element stores are triggered by the outputs of a ring counter and supply the number with, if required, site and time information to a tape punch unit for recording.
