Title: Associative memory
IPC: G11C15/04
Filed: 1973-11-26
Abstract: 1429702 Digital data storage systems G V VITALIEV A D GVINEPADZE A A KOLTSOVA and R V SMIRNOV 26 Nov 1973 54807/73 Heading G4C An associative store is addressed by a search argument register via code converters which convert respective portions of the argument into constant ratio code signals which are applied to respective groups of memory modules. The arrangement is stated to have the advantage of avoiding the use of codes involving so many 1's that noise on non-selected lines interferes with correct operation of the device. The associative portion of the memory comprises an array of modules 1, Fig. 1, each comprising an array of elements 1<SP>1</SP>. When an associative word is to be written in to the memory the tag word is applied to register 5. Groups of bits of the tag are passed to respective converters 7, each of which provides a marking on a constant number of its output lines 2. At the same time a write pulse is applied to certain of the lines 3 so that a 1-bit (for example) is written in to those elements 1 at the intersection of the energized lines 2 arid 3. When a word is to be read from the memory its search argument is applied to register 8 so that a corresponding constant number of lines 2 in each group of lines is energized. Those elements on these lines that are in the 1-state provide a signal on lines 3. Detectors 4 are each connected to some of the lines 3, and each provides an output when all its inputs are energized, thus indicating the column of the memory in which the required word lies. The converter 7 may each comprise an assembly of AND gates (10, Fig. 2, not shown) to provide an output on one of the lines of a group of lines 2, or such an assembly feeding a read-only store (11, Fig. 3, not shown) or feeding an assembly of modulo-2 adders (14, Fig. 4, not shown) to provide an output on more than one of lines 2. The memory may have a mask register (17, Fig. 5, not shown) whose output is combined in OR gates (19) with the search argument from register 8, the outputs of these gates forming the inputs to the converter 7. Reference is made to the performance of various logical operations on two operands, one in elements 1 and the other in an input register. The detectors 4 may be replaced by units (30) associated with groups of modules 1 (Fig. 6, not shown) in the case where a number of stored words are accessed simultaneously. The detectors represented by such a unit are selected in a required order. The detectors 4 may feed a code converter (44) controlling readout from an assembly (34) of bi-stables (35) storing data associated with the words in modules 1 (Fig. 7, not shown). The assembly includes further bi-stables (41) which store the relevant tags, the outputs of these bi-stables being fed back to the input of register 5.

Abstract: 1,221,627. Oximes. STAMICARBON N.V. 11 Nov., 1969 [12 Nov., 1968], No. 55239/69. Heading C2C. The invention relates to the continuous manufacture of oximes by a process wherein a circulating stream of aqueous liquid is passed (1) through a hydroxylamine salt-forming zone in which hydroxylamine is produced by the catalytic hydrogenation of nitric oxide (NO) and (2) through an oxime-forming zone in which the hydroxylamine salt is reacted with a ketone, the loss of nitric oxide from the system being continuously made good. According to the invention, the ammonium ions formed as by-products in the nitric oxide reduction are eliminated by treating the circulating liquid at a temperature of at least 40‹ C. with a mixture of nitric oxide and nitrogen peroxide, whereby the ammonium ions are converted into nitrogen. The invention is exemplified by reference to the production of cyclohexanone oxime. Apparatus is described in which the nitric oxide required for the process is produced by the catalytic oxidation of ammonia.
