Title: Efficient guest physical address to host physical address remapping engine utilization
Inventor: SARIPALLI RAMAKRISHNA
IPC: G06F9/455
Filed: 2009-12-23
Abstract: A hardware remapping engine maps guest physical addresses to host physical addresses for input/output requests. When the number of requests to a first engine 114 exceeds a threshold, requests are diverted to a second engine 116 by reallocation logic 118. The available capacity of the second engine may be checked before the requests are diverted. The number of requests to each engine may be the same proportion of the total capacity of the engine. All the requests from a particular device may be diverted. When the number of requests falls below a threshold, all the requests are sent to the first remapping engine and the second engine is placed in a low power mode. Further remapping engines may also be used.

Abstract: 568,192. Treating solids with liquids. WILKS, K. H. June 23, 1943, No. 10152. [Class 82 (i)] [Also in Groups III and VI] Apparatus for extraction with a hot solvent, comprises a condenser, an extraction vessel and a still characterised in that both the condenser and the extraction vessel are directly in communication at their lower ends with the still, means to shut off the condenser from the still, and a tube opening at one end into the lower part of the still and at the other end into the extraction vessel, being provided, so that on shutting off the condenser, the vapour pressure in the still forces liquid up into the extraction vessel. When a volatile solvent is used, an additional condenser may be connected to the extraction vessel. In Fig. 1, the solid to be extracted is placed in a thimble 6, and the solvent is brought to the boil in still 2, taps 4 (leading to the condenser) and 7 being open and tap 9 closed. , Tap 9 is then opened and taps 4 and 7 closed, and boiling solvent is forced through tube 10 into the extractor 5. When sufficiently full, the extractor is emptied by opening taps 7 and 4. The extract drains back into the still, tap 9 is closed and the operation repeated as many times as necessary. The extraction thimble may be replaced by a porous stone situated in the lower part of the extractor. Fig. 2 shows communication between the still 11 and the condenser formed as a jacket 16 round the extractor 12. Solvent is brought to the boil in the still with the hollow stopper 14 closed and the tap 17 open, liquid being forced up the tube 15 through the filtering disc 13 into the extractor. Tap 14 is then opened, vapour passes into the condenser, heating the extractor, and the extract filters back into the still.

IPC: C01D15/08
Filed: 1954-04-07
Abstract: In the production of lithium carbonate by precipitation from a saturated aqueous solution containing potassium and lithium sulphes, at potassium hydroxide is added to the solution in a molar proportion equivalent to the lithium sulphate present whereby potassium sulphate is precipitated and lithium hydroxide is dissolved as it is formed; the precipitated potassium sulphate is removed by filtration and gaseous carbon dioxide is passed in to precipitate the lithium as carbonate which is filtered and recovered.  The initial solution is preferably treated with potassium hydroxide at room temperature and allowed to stand for a few hours before filtration and the carbonating with gaseous carbon dioxide is then preferably effected in a pressure vessel.  The saturated aqueous sulphate starting solution may be obtained from micaceous silicate minerals known as zinnwaldite.

Filed: 1937-04-14
Abstract: Furs, pelts and hair are dyed, preferably after treatment by a chrome tannage process, with monoazo dyes obtained by coupling an aminonaphthol or an N-derivative thereof with a diazotized amine of the formula <FORM:0493781/IV/1> where X is NH2 or m- or p-NH2.C6H4.NH-and the ring may carry other substituents, e.g. nitro or halogen, but is devoid of sulphonic acid groups.  The materials may also be previously submitted to treatment with alkaline agents and/or other agents capable of increasing the dyeing capacity of the hairy portions, e.g. hypochlorites or phosphates.  The dyeing is preferably commenced under neutral conditions with subsequent addition of acids such as formic or acetic acids.  The usual dyeing assistants may be used.  The temperature of the dyebath is dependent on the materials, varying between 40 and 100 DEG  C.  In example (1) chrome-tanned white rabbit fur is dyed with anthranilic acid --> (alkaline) 1-N-b -hydroxyethylamino-5-naphthol at 70 DEG  C., acetic acid being added during the process.  In further examples and in a table, the above dye is replaced by m-aminobenzoic acid --> (alkaline) 1-acetamino-7-naphthol, 1 : 5-aminonaphthol or 1 - N - b - hydroxyethylamino - 5 - naphthol or --> (acid) 1 : 5 - aminonaphthol; p - aminobenzoic acid --> (alkaline) 1-N-b -hydroxyethylamino-, 1-acetamino- or 1-amino-7-naphthol, or 2 : 7-aminonaphthol, or --> (acid) 1 - N - b  - hydroxyethylamino - 5 - naphthol or 2 : 7-aminonaphthol; 4-amino-21-nitrodiphenylamine-41-carboxylic acid --> (alkaline) 1-N-b -hydroxyethylamino- or 1-amino-5-naphthol.  4 - Amino - 21 - nitrodiphenylamine - 41 - carboxylic acid is obtained by condensing p-phenylenediamine and 3-nitro-4-chlorobenzoic acid.
