Patent GB-971946-A (GB)
Title: Digital information storage apparatus
Inventor: LANIGAN MICHAEL JOHN
IPC: G11C11/38
Filed: 1962-02-20
Abstract: 971,946. Matrix stores. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 19,1963 [Feb. 20,1962], No. 6633/62. Heading G4C. [Also in Division H3] A matrix store includes at each cross-point a tunnel diode and resistor in series and has non- destructive read-out means. As shown, each matrix row W 1 , W 2  &c., comprises an upper and a lower word line, between which are connected n storage elements comprising a tunnel diode such as N 1  and resistor such as R 1  in series. The junction of each tunnel diode and resistor is connected via an ordinary diode such as D 1  to one of the n column lines 1,2,... n, each line being capable of being pulsed via a diode P 1 , . . ., Pn. Reading. To read a row, the potentials of both word lines of the selected row are raised equally by an amount V R/w  and each colum line is pulsed via a negative strobe S thereby drawing a current through the associated tunnel diode insufficient to change its state from "0" to " 1" (ensuring non- destructive read-out), the value of the voltage depending on the value of the digit stored. These voltages may be measured directly or may be compared in voltage comparators VC 1 , . . ., VC n  with the voltage produced by a "dummy" storage element such as N D , R D , a "dummy" element being provided for each row to store a "0" permanently. Writing. To write data in a storage element the lines of the selected row are pulsed by voltages V R/w , a common line C is made more negative, and a strobe pulse S is applied to the selected column line 1,2,..., n. If this storage element is in the "0" state, it is thereby transferred to the one state.  Erasing. To erase a row, unequal pulses V c  are applied to the respective word lines of that row to reduce the voltage across any tunnel diode in the "1" state sufficiently to reset it to the "0" state. Producing row potentials. Each row is supplied with a circuit comprising tunnel diodes A 1 , A 2  connected as shown for the first row. In practice each of A 1 , A 2  may comprise several tunnel diodes in series, or Zener diodes may be employed. Normally, tunnel diodes A 1 ,A 2  are in the "1" state. To produce the read/write pulse V R/w , a current pulse I R/w  is applied to connection C 1  thereby setting tunnel diode A 1  to the "0" state to raise the potential on both the upper and lower word lines. To produce the clear pulse V c , a current pulse I c  is applied to connection C 2  to replace the current flowing through diodes A 1 , A 2  thereby bringing both the upper and lower word lines effectively to earth potential.

Title: Recovery of dicarboxylic acids from mixtures thereof
IPC: C07C51/44
Filed: 1963-02-19
Abstract: Succinic, adipic, and glutaric acids are recovered from a liquor containing them in admixture with one another by fractionally distilling the liquor under reduced pressure and collecting two fractions, the first containing substantially all of the succinic acid and a portion of the glutaric acid, and the second substantially all of the adipic acid and a portion of the glutaric acid; recrystallizing the individual fractions from water to isolate pure succinic acid from the first fraction and pure adipic acid from the second fraction; and obtaining glutaric acid from the combined mother liquors by evaporating them to dryness. Pure glutaric acid may be obtained by distillation of the residue obtained on evaporating the mother liquors and subsequent recrystallisation of the distillate. Pressures of and below 10 mm. Hg. are preferred for the fractional distillation and the temperatures at which the fractions are collected vary with this pressure, being, for example, up to 160 DEG C. for the first fraction and 160 DEG  C. to 275 DEG  C. for the second fraction at 10 mm. Hg.  The initial liquor to be separated may be that obtained by denitrification of the adipic acid mother liquor from the oxidation of cyclohexanol with nitric acid in the presence of an oxidation catalyst.

Abstract: 1,169,822. Copying by scanning. DAINIPPON INK & CHEMICALS Inc. 15 Feb., 1967 [16 Feb., 1966], No. 7300/67. Heading H4F. In a system for reproducing the pattern of a specific colour from a multicolour original, the original on a rotating drum 3 is scanned by a light source 1 or 1<SP>1</SP> and the reflected or transmitted light is separated by means of semireflecting mirrors 7, 8 and colour filters 9, 10, 11 into the three primary colours and the coloured beams focused on to photomultiplier tubes 15, 16 and 17. The resulting electrical signals are amplified in amplifiers 18, 19 and 20 arranged to have amplification factors so that their respective outputs are equal when the specific colour is scanned. The outputs of the amplifiers are compared in differential amplifiers 21 and 22, and their outputs are fed to an AND gate 23 which controls a gate 24 which connects (or disconnects) a power source 25 with a reproducing means 26, e.g. a glow tube, discharge tube, electric etcher or arc etcher. The system preferably operates so that the gate 24 is set open when there is no difference between the outputs of amplifiers 18, 19 and 20, i.e. when differential amplifiers 21 and 22 do not operate, the glow tube 26 lighting when the specific colour is scanned. Image receiving drum 30 rotates and moves in the axial direction synchronously with drum 3. Light sources 1 and 1<SP>1</SP> may be continuous or intermittent light sources, D.C. or A.C. amplifiers being used respectively. If the multicoloured original has variations in tone, i.e. brightness, the intensity of the reflected or transmitted light for the same colours varies but not in direct proportion to the variation in brightness. To reproduce the tonal variations the output of amplifiers 18, 19 and 20 is fed to logarithmic amplifiers 31, 32 and 33 and the voltage of the power source is amplified 34 in accordance with the brightness of the original.
