Title: Method and apparatus for densifying ligno-cellulosic material
Inventor: PETROV YEVGUENIY N
IPC: B27K5/06
Filed: 1996-12-20
Abstract: A method for changing the physical structure of a ligno-cellulosic work piece having a selected grain and a first structural configuration. The first structural configuration preferably includes those structural and physical properties, including density and hardness, that are associated with an unplasticized ligno-cellulosic product. The method includes appropriate stucture for subjecting the ligno-cellulosic workpiece to electromagnetic radiation in the range of about 5 MHz and about 3 GHz to plasticize, e.g., soften, the lignin component of the material. The plasticized workpiece is then compressed along an axis transverse to the grain of the workpiece and stabilizes the workpiece by allowing said softened lignin components to bond together to attain a second structural configuration. The workpiece is compressed only when the moisture content is 30 % or less.

Title: Boitier a blindage electromagnetique avec elements de boitier metalliques verrouillables par une reglette de contacts a ressorts
Inventor: K RBER WERNER
IPC: H05K9/00
Filed: 1997-02-28
Abstract: Ce boîtier à blindage électromagnétique, notamment un bâti, présente des éléments de boîtier métalliques et au moins une réglette de contacts à ressorts. Cette dernière est raccordé à un premier élément de boîtier et est formée de sorte que cet élément puisse simultanément être mis en contact et verrouillé avec un deuxième élément de boîtier. Dans le cas d'un bâti sous forme de boîtier à blindage électromagnétique, une tôle de blindage à étage par exemple peut servir de premier élément de boîtier et un rail transversal peut servir de deuxième élément de boîtier. Le verrouillage sans contrainte de la tôle de blindage à étage et du rail transversal ne nécessite pas de pression supplémentaire. Un vissage de la tôle de blindage à étage est nécessaire uniquement si l'on souhaite obtenir une stabilité supplémentaire par exemple. Il est en outre particulièrement avantageux que les zones marginales, de préférence coudées, de la tôle de blindage à étage ne soient pas recourbées à partir du rail transversal, ne soient donc pas saillantes et permettent un blindage électromagnétique optimal.

Title: Method for permanent emplacement of sensors inside casing
Inventor: MINEAR JOHN W
IPC: E21B47/01
Filed: 1999-02-24
Abstract: An array of sensors is disposed on an umbilical cable attached to tubing extending into a well. The sensor array includes a series of evenly spaced three-component accelerometers individually mounted on biasing members, such as bowspring centralizes fins, which clamp the accelerometers to an outer casing to establish a mechanical coupling between the accelerometers and the surrounding formation. The accelerometers are lightweight such that the biasing members provide sufficient clamping force to ensure mechanical coupling, thereby facilitating the emplacement of the sensor array. The umbilical cable coupling the accelerometers and extending to the surface may include a crush resistant metal coil wrapped around an inner transmission cable which carries power and/or telemetry information from downhole to the surface. The metal coil provides a higher crush resistance and a higher flexibility than comparable solid metal tubing. A wire wrap similar to that used for wireline cables may be provided outside the metal coil for added tensile strength, and an abrasion-resistant plastic coating may also be employed to enhance the longevity of the umbilical cable.

Title: Filterbank structure and method for filtering and separating an information signal into different bands, particularly for audio signals in hearing aids
Inventor: BRENNAN ROBERT
IPC: H03H17/02
Filed: 1998-04-16
Abstract: A filterbank structure is provided which provides a flexible compromise between the conflicting goals of processing delay, filter sharpness, memory usage and band interaction. The filterbank has an adjustable number of bands and a stacking which provides for a selectable shift of band frequencies to one of two discrete sets of center frequencies. The width of the bands and hence the number of the bands is selected depending upon acceptable delay, memory usage, and processing speed required. The flexibility in terms of stacking of the bands provides twice the number of potential band edge placements, which is advantageous for hearing loss fitting, especially at low frequencies. The same filter coefficients can be used for analysis and synthesis, to reduce memory usage.

Title: Process for making particulate compositions
Inventor: BEDELLS ALISON DAWN
IPC: C08J3/215
Filed: 1998-04-01
Abstract: There is described a process for producing a particulate composition comprising the steps of: (a) forming a first dispersion comprising first particles stabilised in a first fluid by a first species in an initial state, the first species changeable between the initial state and a further state, where the initial state provides (directly or indirectly) more stability to the particles within the dispersion than the further state; (b) optionally the step of forming a second dispersion comprising second particles stabilised in a second fluid, miscible with the first fluid, by a second species in the, or another, initial state, the second species also changeable between the, or another, initial state and the, or another, further state, where said initial state provides (directly or indirectly) more stability to the particles within the dispersion than said further state; (c) after the optional step of mixing the first and second dispersions together if the second dispersion was formed in step (b), changing the state(s) of the first and/or optionally second species from the initial state(s) to the further state(s) substantially to induce association between the dispersed particles to form clusters; and (d) binding together the particles within the clusters. A preferred embodiment of the process comprises mixing together two aqueous dispersions of particles (e.g.  pigment particles with particles of latex polymer formed by emulsion polymerisation). The dispersions are stabilised by ionic surfactants of same sign charge. Association of the particles into clusters is induced by adjusting pH to selectively protonate or deprotonate the surfactants. The clusters are grown by aggregation into loose matrices which are fused together to form particles which can be used in electroreprographic toners.
