Title: Memory device with error correction capability and efficient partial word write operation
Inventor: KOHLER ROSS A
IPC: G06F11/10
Filed: 2007-04-26
Abstract: A memory device comprises a memory array and error correction circuitry coupled to the memory array. The memory device is configured to perform at least a partial word write operation and a read operation, with the partial word write operation comprising a read phase and a write phase. The write phase of the partial word write operation occurs in the same clock cycle of the memory device as the read operation by, for example, time multiplexing bitlines of the memory array within the clock cycle between the write phase of the partial word write operation and the read operation. Thus, the partial word write operation appears to a higher-level system incorporating or otherwise utilizing the memory device as if that operation requires only a single clock cycle of the memory device.

Title: Continuous process of producing esters
Inventor: GEDDES KENNETH WILFRED
IPC: C07C69/24
Filed: 1959-03-26
Abstract: A continuous process for the preparation of an ester comprises heating an acid reactant which is less volatile than water with excess of an alcohol which is more volatile than water and the ester produced and which is capable of forming an azeotrope with water, in a reactor to which the reactants are fed separately in countercurrent flow to form an ester, passing a mixture of the vapours of the alcohol and water from the reactor to a distillation column wherein the vapours are fractionally distilled, removing any excess water from the base of the distillation column, recycling the alcohol-water azeotrope in vapour form from the head of the distillation column to the reactor at a point adjacent to that at which the acid reactant is fed thereto, removing a liquid mixture of the ester and the alcohol from the reactor, separating the ester from the alcohol and returning the separated alcohol to the distillation column. The acid reactant is a carboxylic acid, e.g. stearic, maleic, adipic, sebacic, isosebacic, phthalic, isophthalic or terephthalic acid, a carboxylic acid anhydride, e.g. phthalic or maleic anhydride, or a carboxylic ester-acid.  The reactor may be in the form of a series of zones each being heated by independent heating means, and so may be similar to a bubble cap fractionating column.  The alcoholwater azeotrope obtained on fractioning the vapours from the reactor may be returned to several points in the column reactor.  The liquid mixture of ester and alcohol withdrawn from the reactor may be stripped of the alcohol by fractional distillation, if desired, with the aid of steam.  The esterification may be effeced at 110 DEG -250 DEG C., and a catalyst may be present, e.g. sulphuric or toluene sulphonic acid. The preparation of diethyl phthalate is described in detail with reference to a suitable form of apparatus.  The process described in the Provisional Specification is not restricted to the feeding of the reactants in countercurrent flow and includes the use of esters as acid reactant.

Abstract: 557,048 Knitting. KAUFMAN, C. A. July 30, 1942, No. 10666. [Class 74 (ii)] A run-resisting fabric comprises a basic yarn A interlooped in plain knitted courses 1 ... 5 and a separate binder yarn a<SP>1</SP> extending substantially from edge to edge in selected pairs or in every pair of adjoining courses. Both legs of every needle loop and sinker loop are engaged by the binder yarn which is looped around both legs of a needle loop in one course and around both legs of an adjacent sinker loop in the adjoining course. The binder yarn is thinner than the basic yarn. In any pair of courses, e.g., 1, 2, the sinker loops wrapped by the binder yarn are on the same side of the corresponding wrapped needle loop so that the loops of binder yarn extend in the same direction ; in other pairs of courses, e.g., 2, 3, the binder yarn loops extend in the opposite direction. The fabric is knitted by laying a course of loops of the basic yarn A upon the needles, forming a series of loops of the binder yarn a<SP>1</SP> upon the same needles, drawing a binder yarn loop through each basic yarn loop without casting off the latter, transferring each basic yarn loop to the next adjacent needle while retaining the binder yarn loops upon the original needles, and finally knitting another course of basic yarn loops through the previously formed basic yarn and binder yarn loops. Straight-bar machines. The basic yarn loops are transferred to the adjacent needles by points p which can be moved laterally in either direction. The operation of transfer can be effected by a series of cams upon the main cam shaft additional to the usual knitting and fashioning cams, and the cam shaft can be shogged by the timing mechanism to either of three positions.
