Patent GB-1460963-A (GB)
Title: Programme controlled testing system
IPC: G06F11/22
Filed: 1974-02-13
Abstract: 1460963 Programmed test system; testing data stores TAKEDA RIKEN KOGYO KK 13 Feb 1974 [26 Feb 1973] 6522/74 Heading G1U [Also in Division G4] A test system for an addressable device, for example a data store, is characterized in that concurrently in one cycle of the test system (a) data is extracted from an addressed part of the device under test, and (b) the data extracted from the device under test during the preceding cycle is compared with the expected data. Any disagreement, indicating the presence of a fault, causes the test system to enter a fault diagnosis routine. As described a data store 3, Fig. 3, is tested, and cycles of the test system are demarcated by clockpulses P 1 , P 2 ,..., Fig. 4A. At the beginning of cycle P 1  a control portion 1 of the test system emits an address and an item of data. These are stored in registers 2 and 4, respectively, and simultaneously the data is entered, at the specified address, in the store 3 under test. At the instant t 2  the data just entered into the store 3 is read out, Fig. 4F, and at the instant t 3 , Fig. 4H, it is entered into a buffer register 5. At the beginning of cycle P 2  assuming that the comparison (which has not yet been described) that was performed in cycle P 1  was satisfactory, a clockpulse 17 is passed via a gate 19 to enter into registers 13, 14 and 15 respectively, the address, data input and data output of the previous cycle. The data output, in register 15, is then compared 6 with the data input, in register 14, and the result of the comparison, Fig. 4J, sets a JK flip-flop 16 correspondingly at an instant t 4 . The output from the comparator 6 also, via one of gates 20 and 22, prepares the control unit 1 for the cycle P3, so that during cycle P 3  either, as described above, a further address of the store 3 is tested and the output from the store 3 during cycle P 2  is compared with the expected output, or the test system enters a fault diagnosis routine (not described) in respect of the address in store 3 that was tested in cycle P 1 . In a modification, Fig. 5 (not shown) use of the comparison result can be delayed for two cycles. The contents of registers 13, 14 and 15 are displayed in devices 8a, 8b and 8c.

Abstract: 385,793. Electric signalling systems ; luminous colour signals. ORENSTEIN & KOPPEL AKT.-GES., 23, Tempelhofer, Ufer, Berlin. March 7, 1932, No. 6852. Convention date, Oct. 1, 1931. [Classes 40 (i) and 118 (ii).] Lamp signalling - apparatus wherein a danger lamp H light: up automatically, when the clear lamp F is switched out by the changed phase con ditions in a polyphase network which includes an inductance D1 in the common-lead to the lamps F, H, is provided with a substitute danger lamp HN connected in series with an inductance D2 across the main danger lamp H. Condensers C1, C2 are included in the leads to the lamps F, H and are so chosen that when the clear lamp F is lit the voltage drop in the inductance D1 equals the phase voltage across RS so that the danger lamp H will not be lit, while when the clear lamp F is switched out the condenser C2 compensates the new voltage drop in inductance D1 and the danger lamp H therefore lights up. The substitute danger lamp HN will only light if the danger lamp H burns out as otherwise the voltage across the danger lamp H can only produce a small current in lamp HN on account of the series inductance D2. The inductances and condensers may be replaced respectively by condensers and inductances, the connections to the two-phase times S, T thus being interchanged.
