Patent GB-2357505-A (GB)
Title: Process
Inventor: COLLEY STEPHEN WILLIAM
IPC: C07C69/14
Filed: 1999-09-29
Abstract: A process is described for the recovery of substantially pure ethyl acetate from a feedstock comprising ethyl acetate, ethanol and water. This uses a first distillation zone maintained under first distillation conditions effective for distillation therefrom a first distillate comprising ethyl acetate, ethanol, and less than about 10 mol % water. The first distillate is recovered from the first distillation zone and is supplied to a second distillation zone maintained under second distillation conditions which include use of a higher pressure than that of the first distillation zone, which are effective for distillation therefrom of a second distillate comprising ethanol, water, and a minor proportion of ethyl acetate and which yield a substantially pure ethyl acetate bottom product, which is recovered. The second distillate is returned to the first distillation zone. A typical feedstock to the process contains less tan about 20 mol % water which is supplied to the first distillation zone. Typically the first distillation zone is operated at a pressure of less than about 4 bar (2 x 10<SP>5</SP> Pa), while the second distillation zone is preferably operated at a pressure of from about 9 bar (9 x 10<SP>5</SP> bar) absolute to about 15 bar (1.5 x 10<SP>6</SP> Pa) absolute.

Title: Adaptive cellular communication topology
Inventor: SHAKHGILDIAN VAGAN
IPC: H04W16/06
Filed: 2001-07-24
Abstract: In a first time period, eg peak hours, a network is configured with a number of microcells. During a second time interval (off-peak) one of the base stations is used to cover the whole area. The base station providing macro-cellular coverage may transmit at a higher power than during predetermined busy times. Adaptive transmissive arrays may be enabled/ disabled or available antennas allocated to a different number of cell sectors in order to vary the coverage. The macrocell base station may be above roof level, and the microcell below roof level. The set times may be adaptively determined according to traffic levels in the area. Peak hours may correspond to a larger number of users and slower speed and quiet time to a lower number of users and higher speeds. The sleeping base stations may be used to collect uplink information.

Title: An efficient and accurate Pseudo 2-D inversion scheme for multicomponent induction log data
Inventor: KRIEGSHAUSER BERTHOLD
IPC: G01V11/00
Filed: 2002-02-27
Abstract: A fast, efficient and accurate pseudo 2-D inversion scheme (Fig. 4) for resistivity determination of an anisotropic formation (Fig. 3) uses data from a tool (3DEX) (10) comprising three transmitters (101, 103, 105) and three corresponding rereceivers (107, 109, 111) sampling the formation in a plurality of spatial directions. An initial model (311) of the formation including invasion zones is obtained using a conventional multifrequency and/or multispacing logging tool. A pseudo 2-D inversion scheme combines an accurate full 2-D forward solution (313) of the synthetic responses of the earth model with a 1-D approximation (323) of the sensitivity matrix (317) of the horizontally layered anisotropic background model. The timesaving compared to a regular 2-D inversion scheme can be tremendous.

Title: Diver-worn acoustic interrogator-transponder device for locating another diver
Inventor: GOEDEKING PHILIPP
IPC: B63C11/26
Filed: 2004-06-29
Abstract: A device for locating underwater objects, particularly scuba divers in an emergency, comprises an interrogator (transmitter, loudspeaker), a transponder, a receiver having an arrangement of microphones and a microprocessor. The device is integrated into a compact water-resistant housing, worn by each diver. When searching for a second diver, the first diver pushes a button on his device which emits a pulse or pulses of acoustic energy, preferably within the audible range. The transponder on the device worn by the second diver responds with a response acoustic signal, which is received by the microphones on the first diver's device, and the microprocessor calculates the direction of the second diver based on propagation time differences. The location of the diver may be indicated on a display. Only a small amount of current is consumed during normal operation, as the transmitter is only operated in an emergency.

Title: Inspection device for heterogeneous structures
Inventor: ANDREWS DAVID RICHARD
IPC: G01N33/38
Filed: 2005-07-20
Abstract: An inspection device uses sound waves or ultrasound waves to generate images of the interior of structures under test, with particular application to heterogeneous materials, such as concrete. The device has a geometrical arrangement of one of more sonic or ultrasonic transducers 1, 2, 3 which can each transmit or receive waves. The transducers 1, 2, 3 may sense compression or shear sound waves in any polarisation from the structure. The aperture of a transducer is preferably smaller than the wavelength of the sound waves. The transducers may be coplanar or may be profiled to match the surface of the structure, and may have means to register their position on the surface, such as wheels 4 on the housing 7. A coupling means may be used to effectively transmit sound waves into the material of the structure. Images of the interior of the structure under test are created by repeatedly combining and processing echo signals from transducers 1, 2, 3 at a plurality of different locations to reduce the effect of random scattering from the grain particles in the heterogeneous material. The device is preferably portable, handheld and lightweight, with the operator carrying a separate battery in a back pack. The device may create an image of a chosen focal plane within the structure. The linear extent of the transducers 1, 2, 3 is preferably significantly greater than the size of the grains in the material of the structure and greater than the shortest wavelength being used.
