Title: Improvements in or relating to data storage apparatus
Inventor: JAMES JOHN BERNARD
IPC: G11C11/06
Filed: 1958-03-03
Abstract: 875,276. Matrix data stores. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Feb. 26, 1959 [March 3, 1958], No. 6718/58. Class 106 (1). A matrix store for an electronic digital computor in which binary data can be read out column by column in parallel form and reinserted where necessary comprises, as shown, a matrix of 80 columns and 20 rows of magnetic cores (the X numbers denoting the columns, and the Y numbers the rows, while each core is referenced by its X and Y " coordinates "), columns 1, 2, 37-40, 79 and 80 and rows 1 and 2 only being shown, and a distributer D producing output pulses successively at D1-80 on receipt of clock pulses from line CL, each such output pulse passing through the "a" primary winding on its corresponding transformer T1-80 and also the "b" (reversewound) primary on the previous transformer. The numbers of turns in these windings is arranged so that the output pulse in the corresponding wire L1-L80 is sufficient in itself to reset any set core, while that in the previous wire is only able to set a core in combination with a pulse in a row wire such as N1A. Considering a pulse from D2, this will reset any set core in column 2, and pulses will occur in the corresponding sense - windings M1B-M20B (each row is divided into two parts A and B containing the odd and even numbered columns respectively) to act through rectifiers RC, gates GC1 and gates GC2 (opened by a signal on S2B which is energized alternately with S2A by clock pulses acting on trigger TC) to set the corresponding temporary store cores TSB1- TSB20, and provide output signals in parallel on lines SOL1-SOL20. At the next clock pulse D3 is pulsed to read out column 3 on to cores TSA (S2A now opens gates GC2 of the A part-rows) and S2A reads out the information from TSB1-TSB20 via line S3B to energize lines N1B-N20B where appropriate and this together with the pulse from "b"-primary of T2 re-enters the information previously read out from column 2 (since GC2 of the B partrows are closed this setting of cores will not affect cores TSB). If new data is to be entered into the matrix the signal on line S1 is changed to close gates GC1 for the appropriate column read-outs and the new data is presented at S1L1-S1L20 for entry into a temporary store and subsequently into the desired columns. Fig. 2 (not shown) illustrates a modification in which the row and write windings M and N are replaced by a single combined winding.

Title: Improvements in photographic developers
IPC: G03C5/305
Filed: 1947-03-14
Abstract: 626,998. Photographic developers. KODAK, Ltd. March 14, 1947, No. 7198. Convention date, March 14, 1946. [Class 98 (ii)] A photographic developer comprises a strong inorganic base such as caustic soda, a developing agent such as pyrogallic acid, hydroquinone, monomethyl p-aminophenol or glycin, and a mixture or addition compound of cyclohexanone or a substituted cyclohexanone such as p-methyl cyclohexanone with a soluble sulphite or bisulphite. The cyclohexanone bisulphite compounds are believed to undergo a partial hydrolysis in solution, yielding a supply of sulphite ions to replace those oxidised by the atmosphere and so permit production of a strongly alkaline developer such as one of pH over 12, but which has a low sulphite ion concentration and is suitable for maximum contrast or tanning development and yet is not readily darkened by oxidation. To form the mixture or addition compounds sodium or potassium sulphite or metabisulphites may be used and to reduce further the sulphite ion concentration an excess of cyclohexanone is desirable. The description enumerates the superiority of developers made according to the invention over similar developers which incorporate acetaldehyde-, acetone-, methyl ethyl ketone-, and ethylacetoacetatebisulphite compounds as regards prevention of atmospheric darkening, and specifies a developer which gives as much contrast as one containing 1 gram of sodium sulphite per litre, but which oxidises as slowly as one containing 5 grams of sulphite per litre. The use of formaldehyde bisulphite compounds in developers is also mentioned.

They may be prepared by reacting at least four molecular proportions of methylamine or ethylamine in the presence of an inert organic solvent with one molecular proportion of O-(3,4-dichlorophenyl) - phosphorodichloridothioate.  The reaction may be effected at from - 10 DEG  C. to 30 DEG  C. and specified organic solvents are acetone, methyl ethyl ketone, carbon tetrachloride, benzene and methylene chloride.  It is preferred to use an aqueous amine and a water-miscible solvent but gaseous amine may also be used by contacting it portionwise with the phosphorodichloridothioate dissolved in the reaction solvent.  Examples are given for the production of O-3,4-dichlorophenyl)-N,N1-dimethyl (and N,N1-diethyl) phosphorodiamidothioates respectively, the reaction being carried out in each case with an aqueous solution of the corresponding amine which is added portionwise to the O-(3,4-dichlorophenyl) phosphorodichloridothioate dissolved in benzene.  The products are stated to be valuable as pesticides (see Group VI).  The O - (3,4 - dichlorophenyl) - phosphorodichloridothioate employed as starting material may be prepared by reacting an excess of phosphorus thiochloride with an alkali metal salt of 3,4-dichlorophenol.ALSO:A pesticidal composition comprises as the active ingredient an O-(3,4-dichlorophenyl)-N,N1-dialkyl phosphorodiamidothioate having the formula <FORM:0800220/VI/1> in which R is methyl or ethyl (see Group IV (b)).  The product may be dispersed on a finely-divided carrier and employed as a dust or may be employed in an oil, in water emulsion or in water dispersion.
