Abstract: 1511750 Production of cement FIVESCAIL BABCOCK 26 Oct 1976 [28 Oct 1975 2 Aug 1976] 44485/76 Heading F4B An installation suitable for cement production comprises a rotary furnace 12, klinker cooler 14, combustion chamber 10 and first and second material preheaters. The second preheater which branches into two parts comprises cyclones 1 1<SP>1</SP>, 2 2<SP>1</SP>, 3 and 4 and receives exhaust gases from the combustion chamber 10 that are drawn through by a fan 24. The first preheater comprises cyclones 32, 36 and receives exhaust gas from the furnace 12 that may later pass to a raw material drying apparatus 40. The whole of the raw materials are initially introduced into the duct 26 on the discharge side of fan 24 and are carried by gases to the cyclones 28, 28<SP>1</SP> where they are separated and pass to the duets 22, 22<SP>1</SP> of the two parts of the second preheater. Materials issuing from cyclone 2<SP>1</SP> of the second preheater combine to be heated in the second preheater before passing to the combustion chamber 10 while materials issuing from the cyclone 2 of the second preheater, pass to a duct of the first preheater and are heated by exhaust gases from the furnace 12 in the cyclones 36, 32 before passing to the combustion chamber 10 and finally into the furnace. Fans 42 and 44 provide through flow of air and exhaust gases in the installation and an electrofilter 46 removes dust from the gases before they are discharged by a fan 48. In a modified arrangement the first preheater may comprise two branches in the upper stages, Fig. 2 (not shown), with the whole of the raw material being supplied initially to the first preheater instead of the second preheater.

Title: Improvements in degassing and alloying steel
IPC: B22D11/11
Filed: 1961-12-15
Abstract: A method of producing alloy steel comprises evacuating a chamber containing the molten metal until turbulence ceases, adding the alloying elements while preventing entrance of the atmosphere, renewing the turbulence by introducing an inert gas into the steel, and removing the degassed, alloy steel from the chamber. As shown, steel may be poured from a ladle 25 into a vacuum chamber 10 in which, after the steel has been degassed, alloying elements may be added from a container 18. An inert gas, e.g. argon, from a tube 41 may be passed into the metal after slightly opening the stopper 13. When alloying is complete, the gas is shut off, the stopper 13 fully opened and the molten steel passed into a heated chamber 31 after melting a plate 39.  The metal may then pass through a side opening 42 into a <PICT:0961610/C6-C7/1> continuous mould 43 and may then pass to rolls 46 before the centr of the ingot has solidified.

Title: Improvements in or relating to oil-vapour diffusion vacuum pumps
IPC: F04F9/00
Filed: 1964-11-06
Abstract: 1,029,457. Diffusion pumps. COMPAGNIE INDUSTRIELLE FRANCAISE DES TUBES ELECTRONIQUES. Nov. 6, 1964 [Nov. 8, 1963], No. 45312/64. Heading F1E. [Also in Division Bl] In a device for reducing oil loss in oil-vapour diffusion pumps during the fitting of evacuated enclosures or during the accidental ingress of air, the oil vapour flowing through nozzle 3 from the pump strikes the cavity wall 1 and passes through orifice a and deflecting vent hole b. The emerging vapour condenses on wall 1, which is cooled by water circulation through pipe 4, and returns in liquid form through orifices d and e to the pump. Separated gas flows through pipe 5 to the primary pump. If the oil is only aerated it flows through a calibrated annular gap between flange 9 and wall 1 into space V 2 , orifice a and space V 3.  The occluded air is released through vent holes b and liquid oil drains through orifices d, e and through notch F.

Title: Data storage system
IPC: G06F12/08
Filed: 1974-10-18
Abstract: 1488043 Hierarchical memory system INTERNATIONAL BUSINESS MACHINES CORP 18 Oct 1974 [23 Oct 1973] 45317/74 Heading G4A A hierarchical memory system is arranged such that it may be operated using any selected one of a set of constraints on the main storage to buffer storage mapping. The memory is formed of a module or chip, Fig. 4, comprising a main store 42 having 2<SP>n</SP> bit locations and a high speed buffer 44 having 2<SP>k+A</SP> bit locations. The arrangement is such that 2<SP>k</SP>-bit blocks may be moved from the main to the buffer store and vice versa under any one of a number of selection constraints. For example any block may be moved from main store into any one of the 2<SP>A</SP> block locations in the buffer (unconstrained mapping), the location of any block so transferred being indicated by an associative directory (Fig. 3) which is searched with the n - k most significant bits of an n bit main store address loaded in register SAR to produce a corresponding A bit address which, together with the k least significant bits of the main store address, is used to address the buffer in the conventional manner. In practice eight similar memory systems are used so that the n bit main store address results in an eight bit byte being accessed. Alternatively the data in the main store may be divided into one, two, four, ..., 2<SP>A</SP> classes with the constraint that data from a given one of the classes may only be stored in a corresponding section of the buffer store. For operation with the selected constraint, i.e. the selected number of classes, the directory is modified so that up to A bits of the buffer address are provided directly by corresponding (CLASS) bits from the main store address, any remaining bits of the A bits being provided by the directory, and the k least significant bits being taken directly from the main store address as before. To effect block transfers the main memory is addressed as shown in Fig. 4 with a 2<SP>k</SP>-bit block being selected by the most significant n - k bits of the main store address by two decoders and the buffer is addressed by A bits provided either by the block replacement section of the directory or by the class bits of the main store address or both as above so that the block may be transferred in a single address cycle of the main store. The arrangement allows a hardware memory module (Fig. 4) to be used in a variety of modes of operation, the only changes for the various modes being the disabling of sections of the directory (Fig. 3) which may be effected permanently or temporarily, by encode logic 30 in response to control signals, such that the mode may be changed as required. Other conventional features are referred to, e.g. marking a block in the buffer when its data is modified to indicate that the copy in the main store is invalid, replacement algorithms &c.
