Title: Processing audio input signals
Inventor: VERNON CHRISTOPHER DAVID
IPC: H04S1/00
Filed: 2007-04-18
Abstract: A method and apparatus for processing an audio input signal represented as digital samples to produce a stereo output signal (having a left field and a right field) such that said stereo signal emulates the production of said audio signal from a specified audio source location relative to a listening source location. An audio input signal is received. An indication of an audio source location relative to a listening source location (an indicated location) is received. A broadband response file for each of the left field and the right field is selected from a plurality of stored files derived from empirical testing, dependant upon said indicated location. The audio input signal is convolved with each of the selected left field response file and the selected right field response file.

Title: Gas turbine engine with nozzle and porous Coanda surface
Inventor: SMITH ANTHONY GREGORY
IPC: F02K1/00
Filed: 2007-07-25
Abstract: A nozzle 1 is attached to a gas turbine engine 2 and accepts exhaust flow 3 from the engine 2. The nozzle 1 directs the flow at an initial angle to an axial direction of the engine 4 and over a Coanda surface 5 fitted downstream of the exit plane of the nozzle 1. The Coanda surface 5 is porous such that it can allow a tertiary flow 6 to pass from beneath the surface 5 under control of surface valves 7 to separate the exhaust from the surface 5. By rapidly opening and closing the surface valves 7 the exhaust flow can be made to attach and detach repeatedly at high frequency producing significant transfer of momentum and energy from the exhaust to the surrounding ambient flow. The detaching and attaching of the exhaust flow is a thrust vectoring technique for direct transfer of momentum and energy from the exhaust of a gas turbine engine to the surrounding ambient flows in order to improve on propulsive efficiency.

Title: Aseptic container filling
Inventor: SHIPWAY MALCOLM AUSTIN
IPC: B65B3/04
Filed: 2007-08-22
Abstract: Aseptic filling of containers, for example bags 26 of bag-in-box container assemblies is achieved by sealingly engaging an inlet fitting 24 of the bag 26 in a collar 30, which is clamped by a clamp 32 against a housing member 2 to form a sealed chamber 18. Steam under pressure is admitted to the chamber 18 while the inlet fitting 24 is closed, both before and after the contents are dispensed to the bag 26 through a filling tube 6. The steam may be admitted through a plurality of nozzles 20 distributed around the inlet fitting 24. Means 12 may be provided to close and open the inlet fitting by removal and replacement of a cap. The collar 30 may comprise pivotable jaws to engage the inlet fitting. Because tube 18 is relatively small, the steam pressure and temperature can rise rapidly, enabling the sterilising operations to be of short duration. The incoming steam may be directed at the inlet fitting 24 so as to dislodge accumulated bacteria and other contamination.

Title: Incremental annular choke
Inventor: UNGER MICHAEL
IPC: E21B34/00
Filed: 2008-06-23
Abstract: An annular choke mechanism is incorporated into a flow path within the outer housing of the sleeve valve to the interior flow ports of the sliding sleeve member. As the sliding sleeve member is moved axially within the housing, the lateral fluid ports of the sliding sleeve member are aligned within particular bore portions so that the size of the annular space between the fluid ports in the housing and the fluid ports in the sleeve is varied. The annular flow area through the annular space governs the rate of fluid flow through the valve.

Abstract: 297,042. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). April 13, 1927. Ethers and esters of 2-amino-9: 10-anthrahydroquinones and their acyl derivatives. - 2- Acylamino-9 : 10-anthrahydroquinone ethers and esters, in which the acyl group is the residue of an aliphatic carboxylic acid such as acetic or formic acid, are prepared by the catalytic hydrogenation of a 2-acylaminoanthraquinone, and etherifying or esterifying the resulting leuco compound. The hydrogenation is effected under pressure at a low temperature, in solution or suspension, and in presence or absence of an alkali. The products are useful in intermediates for the manufacture of dyestuffs. By treatment with hot alkali, the acyl groups may be split off. According to the examples, 2-acetaminoanthraquinone is first hydrogenated by treatment with hydrogen under 20 atmospheres pressure at ordinary temperature using a nickel catalyst; the starting material is dissolved or suspended in alcohol, caustic soda, pyridine or other tertiary base, or chlorbenzene. The resulting 2-acetamino-9 : 10- anthrahydroquinone is then treated without separation either with dimethyl sulphate to produce the 9: 10-dimethylether, or with chlorsulphonic acid to give the 9 : 10 disulphuric acid ester or with sodium chloracetate to yield the 9 : 10-diacetic acid.
