Title: Process for the production of sulfuric acid
IPC: C01B17/765
Filed: 1966-10-17
Abstract: Sulphuric acid is produced by burning sulphur or sulphur containing compounds in a free oxygen containing gas (generally air) to give a gas stream at a temperature below 1200 DEG  C. containing sulphur dioxide and free oxygen in excess of the stoichiometric amount needed to convert the sulphur dioxide to sulphur trioxide. This stream which preferably contains 10-14% of sulphur dioxide is then cooled to 400-550 DEG  C. and divided into two portions. The first portion may then be diluted with more free oxygen containing gas to a sulphur dioxide content of 6-10% and is fed into a catalytic converter using a catalyst such as platinum or vanadium pentoxide to oxidize the gas to sulphur trioxide.  The converter may be in several stages; external cooling being applied between each stage.  The gas is then cooled to between 100 and 200 DEG  C. and the sulphur trioxide scrubbed out by countercurrent flow with concentrated sulphuric acid. The first portion which contains unreacted sulphur dioxide is then heated to 350-500 DEG  C. by heat exchange with the gases emerging from the catalytic convert of the first portion and is added to the second portion.  The recombined streams are then reacted under the same conditions as the first stream.  In the example 99.1% of the sulphur dioxide formed was converted to sulphuric acid.

Filed: 1973-10-10
Abstract: 1413739 Virtual addressing systems DIGITAL EQUIPMENT CORP 10 Oct 1973 [10 Oct 1972] 47347/73 Heading G4A Apparatus for converting a virtual address to a physical address of a page in a random access memory comprises means for using a first part of the virtual address to read from a store a base page address which is then added to a second part of the address. The resulting sum is concatenated with a third part of the address to provide the physical address. A data processing system employing the apparatus may operate in any of a number of modes, and the related programs are stored in corresponding sections of a random access core memory. The page length is alterable. A set of page address registers is allotted to each mode. When a virtual address is received its first few high order bits e.g. 13-15, Fig. 4, are used to access the corresponding register in the set of registers pertinent to the present mode. The base page address is read from the register to a binary full adder where it is added to the second part, e.g. bits 6-12 of the virtual address. The second part has fewer bits than does the base page address. The resulting sum is concatenated with the third part, e.g. bits 0-5 of the virtual address, so providing a physical address of greater bit length than the virtual address. When a base page address is read from a register a page descriptor is also provided. The descriptor disclosed includes a 3-bit indication of the manner in which the page may be accessed, a page length indicator defining the number of blocks of 32 words comprising the page, and a 1-bit indicating whether the words in the page progress from the top or bottom of the page. By reference to the word direction bit and the page length indicator it is determined whether the block number indicated by bits 6-12 of the virtual address lies within the present page length. If it does not, a new page address replaces that in the selected page address register. This address is that of an unused area in the random access memory sufficiently large to accommodate the required number of blocks of words. The page length word in the descriptor is correspondingly updated.

Abstract: 1482940 Photographic multi-colour material EASTMAN KODAK CO 15 Nov 1974 [16 Nov 1973] 49611/74 Heading G2C Photographic sensitive silver halide multi-colour material comprises a support carrying red- and/or green-sensitive emulsion layers having incorporated colour couplers, and coated thereover a bluesensitive emulsion layer containing the shifted form of a yellow dye bleachable in the presence of image silver by the silver-dye-bleach process. By shifted form is meant the form having its absorption maximum primarily in the U/V region of a dye whose absorption maximum shifts from the U/V at ordinary emulsion pH to the blue region on raising the pH to above about 10. The dye is preferably an azo dye. In preferred embodiments, a support carries in order a red-sensitive emulsion layer  containing a cyan-forming coupler, a green-sensitive layer containing a magenta-forming coupler, a yellow filter layer and a blue-sensitive layer containing the shifted yellow silver-dye-bleachable dye and optionally a minor amount of a yellow-forming coup-. ler. A second blue-sensitive layer containing no yellow dye may be coated thereover. Each of the red- and green-sensitive layers contains higher than usual concentrations of silver halide, e.g. at least 1À5 times the silver halide in the blue layer, overproduction of cyan and magenta dyes in these layers being prevented by using competing couplers in the colour developer. The bleachable yellow dye may be of one of the formulae:- The material is exposed and reversal processed by black and white development, silver-dye-bleaching using a non-fixing bath, e.g. of phenazine, HCl and KBr, to form the yellow image in the blue layer, colour development with a fogging colour developer to form magenta and cyan images in the green and red layers, silver bleaching and fixing. An optional treatment with an alkaline solution which preferably contains a surfactant may be given to produce the yellow form of the dye. A positive colour image having improved sharpness and reduced graininess is obtained.
