Abstract: A method of, and an apparatus for, obtaining double bit error correction capabilities in a large scale integrated (LSI) semiconductor memory system using only single bit error correction, double bit error detection (SEC, DED) logic are disclosed.  The method is based upon the statistical assumption that in a large scale integrated semiconductor memory, substan-tially all errors in the data bits that make up a data word are initially a single bit error and that increasing multiple, i.e., double, triple, etc., bit errors occur in a direct increas-ing ratio of the use or selection of the data word.  In the present invention, all data words are priorly tested to be error free.  Subsequent detection of single bit errors results in the correction of the single bit error and the storage of the single bit error correcting syndrome bits in a syndrome bit memory.  Subsequent detection of double bit errors, in the previously single bit error detected and corrected data words, results in the correction, by single bit error correcting syndrome bits, of the previously detected single bit error.  This single bit error corrected data word is then again single bit error corrected, i.e., two successive single bit error corrections, to provide a twice corrected double bit error data word.

Abstract: "Method and apparatus for folding a cardboard sheet along a straight fold line".             ABSTRACT OF THE DISCLOSURE The problem of loss of strength in cardboard along a line of fold due to stretching and breaking of fibres on the outside of the fold is overcome by providing a machine having a support surface against which the sheet of cardboard which is to be folded is held by an element which has a knife edge.  The support surface is provided by a taut flexible sheet material which extends around a rotatable and movable roller 8.  On operation of the machine, the roller 8 is moved around the knife edge, its longitudinal axis being kept parallel to the knife edge, thereby making a fold in the sheet and the cardboard.  The flexible sheet which contacts the cardboard has a high coefficient of friction with respect to cardboard. This restrains the cardboard fibres on the outerside of the cardboard as the fold is made preventing their stretching and breaking and thereby providing an unweakened fold.

Granted: 1982-11-16
Abstract: ABSTRACT             CONTINUOUS CASTING METHOD FOR DEFINED SHAPES OF THIN SHEET Defined shapes of thin metallic sheet are continuously formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body.  The surface of the chill body where-on the shaped parts are formed is provided with raised or lowered domains corresponding in outline to that of the desired defined shape.  As the metal is cast, as a thin sheet against the chill surface, discontinuities arise in the sheet at the walls of the raised or lowered domains defining the desired shape so that sheet product of defined shape is obtained, as if punched out from a continuous strip of the metal.
