Abstract: 1479739 Positive dye images from diffusion transfer material FUJI PHOTO FILM CO Ltd 18 Sept 1974 [18 Sept 1973] 40757/74 Heading G2C At least one secondary positive dye image is formed from a film unit having a primary positive image on a white background and obtained by spreading an alkaline processing composition as a layer between (a) an image-receiving element having a transparent support through which the primary positive image to be formed may be observed, and (b) an imagewise exposed negative light-sensitive element comprising a transparent support having thereon at least two negative-type silver halide emulsion layers, each emulsion layer being sensitive to a different spectral region, and having associated therewith a first dye-providing material capable of providing, upon development, a diffusible dye or a precursor thereof in a positive imagewise distribution and a second dye-providing material capable of providing a complementary negative imagewise distribution of a non-diffusible dye, by (i) delammating the negative element after development from the receiving element, (ii) oxidizing the silver image in the developed negative element, (iii) dissolving out the oxidizing silver together with residual silver halide to prepare a colour negative, (iv) imagewise exposing to light, through the thusprepared colour negative, a multi-colour photographic print material containing at least two incorporated coupler negative-type silver halide emulsion layers and (v) developing the exposed print material with an alkaline aqueous solution containing an aromatic primary amine colour developer. The first dye-providing material may be a diffusible dye releasing coupler and be used together with a second dye-providing material which is a coupler capable of forming a non-diffusible dye. The diffusible dye releasing coupler may be present in a layer, adjacent the negative-type silver halide emulsion layer, containing physical development nuclei, see Ex. 1, 2 and 4. Each silver halide emulsion layer may contain a development inhibitorreleasing coupler and a diffusible dye releasing coupler may be present in an adjacent layer containing spontaneously reducible silver salt which is slightly soluble in water, see Ex. 3 and 5. In Ex. 2 the image-receiving element comprises a white, light-reflecting layer treated with a 1% acetone solution of polyethylene glycol (1000) monocetyl ether to form a layer 0.1 micron thick.

Abstract: 1357648 Photo-electric colour printing registration monitoring SIEMENS AG 2 Sept 1971 [8 Sept 1970J 41087/71 Heading G1A The edges of coloured areas of a printed web in a rotary colour printing machine are monitored for colour registration by a photo-electric arrangement comprising photo-cells 10, 11, 12, 16 to which light reflected by the web is applied, the first three being made responsive to yellow, red or blue by filters 7, 8, 9, and 16 being responsive to low intensity reflection by black. Colour signals are selectable by switch 18 and white light which includes the three colours provides an output via "AND" gate 19. The system compares one such signal developed at the edge of a coloured area with another similar signal or with a roller position signal. The black signal from 16 raises the gain of amplifiers 13-15 but not to a level which would operate switch 20.

Abstract: 1,028,767. Semi-conductor devices. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Sept. 16, 1963 [Oct. 31, 1962; March 22, 1963; April 23, 1963; July 31, 1963], Nos. 41189/62, 11420/63, 15945/63 and 30342/63. Heading H1K. A semi-conductor device with reduced field at the periphery of a PN junction comprises a semi-conductor slice with a PN junction having a mid-portion near one surface and a second portion near the other surface, the depletion layer adjacent the junction extending further at the surface region than it does at the midportion of the junction. Fig. 3 of Specification 1,028,767 shows junction element comprising a high resistivity N-type silicon crystal with a peripheral P-type region 4 produced by diffusing gallium into the surface of a crystal and then cutting it into slices. The crystal is soldered to molybdenum disc 6 by means of an aluminium-silicon alloy resulting in the production of P-layer 10 and tungsten contact 9 is soldered to the N-region of the crystal by means of gold alloy 8. Fig. 7 of Specification 1,028,767 shows a gate controlled PNPN device in which an N-type silicon crystal is subjected to diffusion of gallium to produce a surface P-type layer 36, part of the material then being removed to expose the N-type surface at 34 while leaving a central portion 40 containing PN junction 42. A further N-type region 46 is produced to form another PN junction, ohmic electrodes 48 and 45 being provided to N-type region 46 and P-type region 41. The crystal is soldered to base contact 31. Removal of the material to expose surface 34 may be by etching or grinding and jet etching may be used to undercut region 41 and so decrease the electric field at the surface adjacent the PN junction by increasing the surface length of the depletion zone. Figs. 1 and 2 of Specification 1,028,767 show alternative arrangements in which the P-type region extends along the opposite surface (5a in Fig. 1) or possesses a thickened portion, 5b in Fig. 2. These configurations are said to extend the surface length b of the depletion zone at the region adjacent the exposed end 7 of the junction, compared with the width a of the depletion layer in the central portion.

Title: Data storage circuits
IPC: G11C15/04
Filed: 1974-09-23
Abstract: 1486843 Transistor memory circuits SIEMENS AG 23 Sept 1974 [24 Sept 1973] 41282/74 Heading H3T A data-storage cell comprises two arms connected in parallel between supply terminals 7, 17 via a common load resistor 6, each arm comprising an MNOS storage transistor 1 or 2 and a respective switching transistor 3 or 4, information to be written in, or compared with previously stored information being applied to the control inputs 9, 10 of the switching transistors and write-in pulses being applied to the gates of the MNOS transistors. To write a "1" into the circuit, a negative pulse is applied to line 9 at the same time as a large negative "write" pulse is applied to line 8. This causes the inversion layer of transistor 3 to take up earth potential, so that the negative write pulse is effective to switch the threshold of transistor 1 from - 2 v. to - 12 v. Transistor 4 receives at its input 10 the complement of the signal at input 9 and is not turned on, so that the threshold of transistor 2 remains at - 2 v. To read out the stored data, line 8 is supplied with a read signal which is the mean of the two threshold signals. If now signals the same as those stored in 1, 2 are applied to inputs 9, 10 transistors 3, 4 are not turned on and output 5 remains at the potential of point 7. If they differ, either branch 1, 3 or branch 2, 4 conducts (depending on the stored data) and output 5 takes up the potential of point 17. In a first modification, Fig. 2 (not shown) connections are made to the substrates of transistors 1, 2 and the "write" pulse is applied between the respective gate and substrate of the transistor whose threshold is to be switched. In a second modification, Fig. 3 (not shown) the two arms use transistors of opposite conductivity type, reducing the number of input connections.

Title: Improvements in the separation of liquid mixtures into their components
Inventor: POEHLER GUENTER
IPC: B01D3/14
Filed: 1958-12-30
Abstract: <PICT:0900457/III/1> A liquid mixture, which contains material of low volatility, is separated into fractions by introducing it through pipe 1 into distillation column 3 the base of which is connected, by pipes 7 and 9, to a tubular evaporator 8; the base of the column and/or the tubular evaporator being also connected to a film-evaporator 12.  Non-volatile material is withdrawn from the film-evaporator via pipe 13; and the volatile fraction is removed from the head of the column via dephlegmator 6 and pipe 10.  In the embodiment shown, the vapour withdrawn from the film-evaporator via pipe 14 is condensed; and the condensate is introduced via pipe 22 into the column with fresh feed.  The film-evaporator may be maintained at low pressure by a vacuum pump connected to pipe 19. The level of the liquid in the base of the column is maintained constant by valve 15.  The operation is preferably conducted so that the bottoms product contains 40 to 60% of the low-volatile material. The process is suitable for fractionating the crude products of organic syntheses; and the heat of reaction may be used to preheat in heat-exchanger 2 the feed to the column.  There are five examples, which relate to the production of cyclohexanol, dicyclohexylamine, dichlorbutane, adiponitrile, and beta-naphthol.
