Title: Improvements in and relating to the production of potassium nitrate with simultaneous obtaining of dimagnesium phosphate
IPC: C05B9/00
Filed: 1929-10-11
Abstract: 329,939. Chemieverfahren-Ges. Nov. 28, 1928, [Convention date]. Magnesium phosphate; potassium nitrate.-A process for producing potassium nitrate with the simultaneous production of dimagnesium phosphate is characterized by decomposing crude phosphate with nitric acid, and potassium sulphate, and adding to the solution obtained bv the removal of gypsum, magnesium carbonate, hydroxide or oxide, or a mixture or compound of these to such an extent that the bulk of the phosphate is precipitated as pure, crystalline dimagnesium phosphate. The remaining solution containing, say, 1 per cent phosphorus pentoxide is treated with more magnesium carbonate to precipitate completely the phosphoric acid as trimagnesium phosphate, which may subsequently be used to precipitate dimagnesium phosphate, Potassium nitrate is obtained from the resulting solution by evaporation and cooling, or by cooling alone.

Title: Photo-conductive targets for television pick-up tubes
IPC: H01L31/08
Filed: 1975-07-24
Abstract: 1516122 Image-tube targets; image pick-up tubes ROBERT BOSCH GmbH 24 July 1975 [1 Aug 1974] 30950/75 Headings H1K and H1D A photoconductive target for a television pick-up tube comprises a photoconductive layer 2 (Fig. 1) having on one surface a layer 4 capable of injecting charge carriers into the layer 2 and, between the layers 2 and 4, a barrier layer 3, containing trapping centres which, except in the presence of incident light on the photoconductive layer 2, prevents the charge injection from occurring. Photoinduced carriers from the layer 2 can fill the trapping centres, allowing injection to take place to a degree determined by the strength of the photocurrent, which is thus amplified in a manner analogous to the operation of an openbase phototransistor. The trapping centres may, if both layers 2 and 4 are N-type, e.g. respectively of CdSe and ZnSe, ZnS, As 2 S 3 , Sb 2 S 3 , calcium fluoride, magnesium fluoride or silicon oxide, be acceptors, e.g. oxygen or a halogen absorbed into the surface of the layer 2 prior to deposition by vacuum evaporation of the layer 4 or incorporated into the layer 2 during a recrystallization step following vapour deposition thereof. If both layers 2 and 4 are P-type the trapping centres may be donors. The layers 2 and 4 may be of opposite conductivity types, or the layer 4 may be insulating. In Fig. 1 the injecting layer 4 is located at the electron-beam scanned side of the layer 2, whereas in Fig. 2 it is located at the incidentlight side. In the latter case a P-type layer 6 may be provided to prevent the injection of electrons from the electron beam 5 into the photoconductive layer 2<SP>1</SP>. In the Fig. 1 embodiment a semi-conductor layer of greater energy gap than the layer 2 (e.g. ZnSe) may be provided between the layer 2 and the transparent signal electrode 1 to increase the blue resistivity.

Title: Coincident-current memories
Filed: 1964-08-04
Abstract: 1,062,618. Circuits employing bi-stable magnetic elements. RADIO CORPORATION OF AMERICA. Aug. 4, 1964 [Aug. 22, 1963], No. 31548/64. Heading H3B. [Also in Division H1] A memory element in a coincident current memory comprises a magnetic sheet having first and second parallel conductors embedded therein in different parallel planes, and third and fourth parallel conductors embedded in the sheet in a plane crossing the first and second conductors. In Figs. 4 and 5, x and y conductors define, in the regions where they are parallel to each other, word locations (e.g. x 1 , y 1 ) and digit conductors d and return digit conductors d<SP>1</SP> define bit storage locations. Coincident positive half-currents in an x and a y conductor select a word, and a flux #xy is set up in the magnetic material surrounding the conductors (Fig. 3). Positive or negative currents are simultaneously passed through the digit conductor to write a " 1 " or a " 0 " and set up fluxes # d  and # d <SP>1</SP> which together with #xy produce resultant fluxes #r and #r<SP>1</SP>, as shown. Read-out is achieved by passing negative currents through the x and y conductors to rotate the remanent flux loops and induce output currents in conductors d, d<SP>1</SP>. In a modification the joined ends of conductors d, d<SP>1</SP> are earthed so that the conductors can be used for storing different bits of information. The device is constructed by allowing thin layers of ferrite slurry to dry on substrates, printing conductors on the layers, assembling the layers in a sandwich, then subjecting the assembly to pressure and firing at 1200 C. to produce a homogeneous sintered ferrite sheet with its embedded conductors.
