Title: A Speech Recognition Accelerator Circuit and Speech Recogniser
Inventor: LARRI GUY
IPC: G10L15/28
Filed: 2005-09-14
Abstract: An accelerator circuit for a speech recognition system, the accelerator comprising: calculating means for calculating a distance indicating the similarity between a feature vector and a predetermined acoustic state of an acoustic model, wherein the feature vector comprises a plurality of extracted and/or derived quantities from an audio signal during a defined audio time frame; means for receiving or storing compressed data representing said acoustic model; a decompressor for decompressing said compressed data for all states or selected states of the acoustic model, wherein the decompressed data is sent to the calculating means; and output means for outputting calculated distances to another part of the speech recognition circuit. The speech recognition system may comprise a lexical tree and an acoustic model and dual processors. Various hardware configurations are envisaged including the use of dual processors or multiple processors, at least one of which is in the accelerator circuit. The distance may be the Mahalanobis distance.

Title: Recovery of high purity isoprene from a hydrocarbon fraction containing acetylenes
IPC: C07C7/08
Filed: 1960-03-22
Abstract: <PICT:0892470/III/1> Isoprene of high purity is recovered from a hydrocarbon fraction containing also a - and b -acetylenes by a process wherein the mixture is subjected to extractive distillation using acetone or acetonitrile as the solvent, and the isoprene-rich fraction is further fractionated, the a -acetylenes being removed by withdrawing a stream from an intermediate point of the extractive distillation column and the b -acetylenes being removed as a side-stream from the final fractionation column.  As shown, a mixture containing olefins and diolefines of 4-9 carbon atoms, such as may be obtained from a light steam-cracked distillate, is fed through line 1 and heater 2 to a vessel 4 in which it is left at 180 DEG -240 DEG F. under pressure for 1-30 hours to effect the selective dimerization of cyclodienes.  The mixture is then passed to a primary fractionator 6, from which an overhead stream containing C4 and C5 hydrocarbons is passed through line 8 to the upper part 9 of an extractive distillation column to which acetone or acetonitrile is supplied, whereby an isoprene-rich fraction is obtained as bottom product, the olefins and any paraffins which may be present being removed as top product and passed to a washing tower 11 before they are withdrawn through line 12 for further processing.  The bottom product from the extractive distillation column is passed to a stripper 16, from which the hydrocarbons pass overhead to a washing tower 19 and solvent passes back through line 17 to the extractive distillation column.  A purge stream containing a -acetylenes is withdrawn from the extractive distillation column through line 27 in a proportion of 3-10% by weight, based on the extract stream passed to the stripper 16.  The isoprene-rich fraction from the top of the wash tower 19 passes to a fractionator 24, from which isoprene of high purity is withdrawn through line 28.  A purge stream containing b -acetylenes is taken from the top of the fractionator 24 through line 25 in a proportion of 5-15% by weight, based on the isoprene product. Comparative data are given for a process according to the invention and a known extractive distillation process for recovering isoprene.

Title: Improvements in a method of applying a veneer lining upon the inner wall of hot tops
IPC: B22D7/10
Filed: 1956-04-06
Abstract: 817,869. Coating and lining moulds and cores. FERRO ENGINEERING CO. April 6, 1956 [April 12, 1955], No. 10555/56. Class 83 (1). A veneer of refractory material is applied to the inner wall of an annular open-ended hot-top by providing, in association with one of the open ends of the hot-top, an annular inwardlydirected projection, telescopically moving, relative to each other, a mandrel and the hot-top so that the mandrel is disposed in the hot-top, and introducing plastic-refractory into the space between the mandrel and the inner wall of the hot-top, the mandrel being withdrawn before the material has set. A hot-top 10, Fig. 2, which includes a refractory-ring 12 forming said annular projection is moved on a conveyer 1 to beneath a fluid-pressure ram 2. The ram is moved into the hot-top and a quantity of plastic granular refractory 13, placed within the hottop, is caused to flow upwardly between the ram head and the inner surface of the hot-top. The ram is then withdrawn and the hot-top moved to a position where the coating is dried and excess material on the supporting-plate 9 removed. In a modification, Fig. 3, the hot-top rests on a base 14 having an upstanding hollowmandrel 15, and the coating material is blown into the hollow interior of the mandrel and through holes 17, 18 therein into the gap between the mandrel and the hot-top. In a further modification, Fig. 4, a coating material receptacle 24 is supported on a stationary floor 23 and a mandrel 29, having a hollow portion 30, depends from the underside of said floor. A hot-top 36 is moved upwardly over the mandrel on a fluid-actuated platform 33 forming part of a conveyer 32. The coating material is forced by a plunger 27 through the conduit 26 and radial passages 31 in the mandrel, into the gap between the mandrel and the hot-top. The hot-top refractory ring 38, held to the hot-top casing by clips &c., is engaged by a metal ring 39, connected to guide-rods 40, and when the coated hot-top is lowered, the inner wall portion of the ring 38 acts as a stripper, the ring 39 following the downward movement until halted by stops on the guide-rods 40. In a further modification, Fig. 7, the hot-top 80 is brought on an overhead rail and lowered over the mandrel 70. The coating-material is injected through passages 73 which are aligned with notches 83, Fig. 8, in the lower part of the hottop casing.
