Patent GB-1514555-A (GB)
Title: Data processing systems
IPC: G06F12/1081
Filed: 1975-09-16
Abstract: 1514555 Data processing system SIEMENS AG 16 Sept 1975 [17 Sept 1974] 38092/75 Addition to 1447680 Heading G4A] The Parent Specification is modified to enable larger storage systems to be handled by dividing the data in the chain list store into pages in a conventional hierarchical manner using a higher order segment table providing the base addresses of a group of pages each storing chain list entries. Thus the chain list pages can be treated within the virtual memory system in exactly the same way as other pages of stored data, i.e. they can be transferred in and out of the working store as required. Input/output operations between peripherals and the working store DM of a virtual memory system proceed as in the Parent Specification by incrementing or decrementing (depending on signal DTB) the byte address part DR1 of a real address comprising byte DR1 and page DR2 parts for each byte of data transferred until a page boundary is crossed indicated by a carry PCR from register DR1. Since the next page into or from which data is to be transferred is not necessarily stored in the next real page address the old page part DR2 of the address is transferred to register CR4 which, in combination with the current chain list page PCT base address in register CR3, addresses the appropriate chain list entry. Each such entry, as in the Parent, provides the real page address of the next page which is to be used in the I/O operation which is fed to register DR2 to enable the operation to continue. Each entry however also includes a four bit indication (bits 5-8) and a bit S which is "1" when the next chain list entry is not within the same page. In such a case the four bits are fed at any time during execution of the I/O operation in the newly selected page to register CR2 which, in combination with register CR1 which contains the fixed base address of the higher order segment table SPT, addresses the segment table. Each entry in the segment table contains two addresses one of which is selected in unit SC, in accordance with whether the I/O operation was proceeding with incrementing or decrementing of the byte addresses, and fed to register CR3 where it provides the base address of the next chain list page. This page is accessed when the next page boundary is crossed during execution of the I/O operation at an entry determined by the contents of register CR4, transferred from DR2 as before, to provide the real page address of the page which is to be used in the I/O operation. This arrangement allows any access to the chain list store to be completed in a single store access since even when a chain list page boundary is crossed the address of the next chain list page is obtained during execution of the I/O operation before the access to the chain list is required. The hierarchy of the chain list may be extended by providing three or more levels depending on the number of entries required and the size of a page.

Title: Iron ore magnetic roast process
IPC: C21B13/14
Filed: 1960-11-08
Abstract: <PICT:0922019/III/1> Magnetic particles containing Fe3O4 are formed from non-magnetic iron ore particles, e.g. haematite, Fe2O3, by contacting the ore in a preheating zone with p  gases from a reducing zone which have been passed via a combustion zone to raise their temperature to, e.g. 1500 DEG -1700 DEG F., contacting the preheated ore in a reducing zone with a reducing gas, at preferably 1100 DEG -1500 DEG F., which contains a major proportion of steam mixed with H2 and CO2 and contacting the reduced ore in a cooling zone, at preferably 750 DEG -1500 DEG F., with a gas at lower temperature than the reducing zone, containing steam, CO, CO2 and hydrocarbon, which is then used as the reducing gas. Crushed haematite ore (e.g. containing 30-35% Fe) is fed through 19 to fluidized fines drier 3 and thence through 4 and hopper 2 to a refractory lined steel rotary kiln 1.  The ore passes by gravity through the three zones of kiln 1 in countercurrent to the gases. Steam, at 212 DEG -400 DEG F., entering at 14 and hydrocarbon vapours, natural gas or liquid hydrocarbons, e.g. naphtha, kerosene or heating oil, entering at 15, pass through the cooling zone where part of the hydrocarbons and CO2 react with the steam to form H2 and CO2.  Other reducing gas, e.g. producer or water gas, may be added through 16.  The resulting reducing gases pass through the reducing zone and the remaining reducing constituents are burnt with air injected at 11 before entering the preheating zone.  Fuel may be added at 11 to increase the temperature.  A portion of the gases from kiln 1 may pass through 18 to drier 3 and thence through cyclone 21, the remainder of the gas passes through 23 to waste at 25 through waste heat boiler 24 forming steam which is fed to the kiln at 14.  In an alternative apparatus (Fig. 2 not shown), the preheating is carried out in a separate kiln from the reducing and cooling.  Fe3O4 is withdrawn at 13 for further cooling and processing, e.g. grinding, magnetic separation, briquetting or pelletizing.  Fixed vertical kilns and fluidized beds may be used in place of a rotary kiln.

Title: Method of and apparatus for producing artificial filaments by wet spinning
IPC: D01D5/06
Filed: 1960-11-10
Abstract: 965,660. Wet spinning apparatus. Z. RYBICKI, M. KOPA, E. WEJNER, J. KLEKOT, and Z. WROCLAWSKI. Nov. 10, 1960 [Nov. 18, 1959], No. 38599/60. Heading B5B. In a wet-spinning process for the production of artificial filaments, particularly by the viscose process, the bundle of filaments withdrawn from the bath passes directly through a liquid seal continuous with the bath to a closed space maintained at subatmospheric pressure, is then passed through a degassing bath contained in this space in which degassing bath both gases and vapours are removed from the filaments under subatmospheric pressure, and is finally withdrawn from the space through a further liquid seal. As shown in Fig. 1, viscose supplied to a spinneret 1 submerged in the spinning bath 2 in the container 3 is extruded to form a bundle of filaments which is drawn up a barometric pipe or column 4 the bottom of which is submerged in the bath 2 and the top of which terminates in an evacuated chamber 5 containing filament storage and forwarding rolls 6. The spinning bath liquid drawn up the pipe 4 is discharged into the chamber 5 to form a degassing bath which is maintained at a temperature above that of the spinning bath in the container 3 by means of a heater 14. The filament bundle which has been drawn up the pipe 4 by the storage and forwarding rolls 6 is then drawn down a second barometric column 7 and through a water seal 12. The degassing bath overflows from the evacuated chamber 5 down the barometric column 8 into the vessel 17 in which it forms a liquid seal before overflowing therefrom. The spinning bath drawn up the pipe 4 passes through the overflow 13 to the degasifier 9 containing Raschig rings and then through the hydraulically sealed conduit 18 into the receiver 15 to which fresh spinning bath liquid is added to make up for loss of bath liquid due to the carrying away of liquid by the bundle of filaments. The bath liquid is then returned to the container 3 by the pump 16. The gases and vapours removed from the filaments and spinning bath liquid in the chamber 5 and degasifier 9 are drawn off through the conduit 9 by means of vacuum pump 11 and delivered to condensing and absorbing devices. For the complete removal of volatile sulphur compounds from regenerated cellulose filaments produced from viscose, it is necessary to provide a sufficient period of residence of the filament bundle in the chamber 5 by means of the storage rolls 6 over which the filament bundle is caused to pass the appropriate number of wraps. Instead of rolls 6, fixed guide members of, for example, semi-circular cross-section and consisting of smooth-surfaced porcelain or other acid resisting material may be provided. Two other embodiments of the apparatus of the invention are described and illustrated. The method and apparatus of the invention enables all the volatile sulphur compounds formed during the spinning of viscose to be recovered.
