Title: An associative memory
IPC: G11C15/04
Filed: 1969-09-08
Abstract: 1278664 Associative memory COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 8 Sept 1969 [9 Sept 1968] 44363/69 Heading G4C An associative memory comprises a matrix of storage cells, first means for enabling the cells along at least one column of the matrix for associative search interrogation, said means defining for each read or write operation the cells which are to contain associated bits; second means for applying a search bit to the cells along said at least one column; and third means interconnecting all cells of a row to enable the cells of the row, when the cell of the row relating to said column holds a bit in agreement with the search bit, to provide read-out of the contents of at least some of the cells of the row. The matrix comprises a number of columns of modules 5mo to 5mn (Fig. 2) and a number of rows 5mo to 500, each module comprising a unit as shown in Fig. 1 but arranged at right angles, the module including 8 bi-stables 20 which may be formed as one integrated circuit chip. Each column of bi-stables is connected to a write line Wi, an associative search line I i  and a bit value line L i , and each row is connected to a control line Y k . Each word is stored in the matrix along one bi-stable row memory location, the word comprising data bits and associative address bits. The address bits may be in fixed or non-fixed positions within the word, the non-fixed positions being defined by program control. For an associative search if a search bit (or bits) equals the specific address bit (or bits) the word of that address bit is read out. If a number of words are to be read out a priority unit 60 intervenes. Associative Search (see Fig. 1).-A signal goes down line I i  followed shortly after by a signal down line L i . If the bit in line L i  and the bit in the bi-stable 20 do not coincide, a true signal goes to line 17. If the bits do coincide a false signal goes to line 17, as is the case if the bi-stable in that column is not searched. If all the signals in lines 17 give false signals (i.e. the bits coincide or they are not searched) inverter 31 gives a true signal to line Y k . If any one line 17 of a row gives a true signal (non-coincidence of bits) a false signal goes to line Y k . If Y k  is true, feedback through AND gate 23 reads out the bit down line D i  simultaneously with all other bits of the word to a D register 63 (Fig. 2). Data Recording.-Line Wi is enabled then line L i . The inverters 33, 34 allow writing by one source of one location to the exclusion of those with a raised Y line. Erasure.-The W wires are energized and the I and L wires left unenergized. Other circuits include a write control circuit 61, an I register 61 for holding the control word and an L register which acts as a general input register for the memory connected to the computer. It is possible to search for an empty location using flag bits.

Title: Method of annealing and decarburising electrical steel
IPC: C21D3/04
Filed: 1962-12-11
Abstract: Scale-free electrical steel laminations containing 0-4.5% silicon are treated by (a) heating in an oxidizing atmosphere, e.g. one containing water vapour and having a dewpoint of 100 DEG C. at a suitable temperature, e.g. 200-600 DEG C. to produce an oxide film, (b) heating further to an annealing temperature, which may be 700-900 DEG C., in an inert atmosphere, e.g. nitrogen, to cause decarburization and to develop the desired magnetic properties, (c) cooling, (d) applying an insulating coating. The latter may be brought about by interrupting the cooling at a suitable temperature, e.g. 200-500 DEG C., and holding the steel in an oxidizing atmosphere.  The process may be continuous or batchwise.

Title: Data transmission systems
IPC: H04L1/00
Filed: 1962-12-13
Abstract: 1,021,563. Data transmission. TELETYPE CORPORATION. Dec. 13, 1962 [Dec. 28, 1961], No. 47064/62. Heading H4P. In an error-correcting data transmission system in which character signals are sent in blocks of several signals a check signal is transmitted, this signal being indicative of the number of bits of one kind in each of the levels of the block. At the receiver the check signal is compared with a signal derived from the received block, and if the signals are not identical the receiver cancels the recording of the block and the transmitter repeats the block. To permit detection of inversion of two like bits a second check signal is transmitted. The embodiment described uses a block of 288 characters. The code signals are read from punched (or magnetic) tape and converted to serial form by way of a shift register before transmission. At the receiver the signals are converted to parallel form for operating a tape punch. Both the transmitter and the receiver include a bi-stable unit for each of the character levels so that each of the units indicates, over the block of signals, whether the total number of marks in its level is odd or even. These bistable units feed a second set of such units to form a second check signal. When the 288 signals have been transmitted the states of the two sets of bi-stable units are transmitted. The receiver derives check signals which should be identical to the received check signals. If they are not, the transmitter repeats the block and check signals. If the block is now correctly received it is recorded in the tape and, simultaneously, the faulty data which preceded it is cancelled by overpunching. Reference is made to the addition of a parity bit to each character. The receiver includes means for suppressing short start signals, and if it detects a short block it causes that block to be repeated. A dirty contact monitor is provided at the transmitter.
