Title: Downhole separation of water and solids from an oil mixture
Inventor: NILSEN FINN PATRICK
IPC: E21B43/38
Filed: 1998-02-13
Abstract: An apparatus for separating water and solids from an oil/water mixture is located downhole within the pipework of an oil-well and comprises hydrocyclone 6 and centrifugal device 10. Hydrocyclone 6 achieves separation of the solids from the oil/water mixture and said mixture is then separated using centrifugal device 10. Oil-continuous or water-continuous mixtures can be separated. The separated oil is then pumped to a platform above sea-level/on the surface. Means for causing coalescence such as electrostatic coalescence unit 8 may be included prior to the centrifugal device 10 in order to promote water droplet formation and thus more efficient oil/water separation. A minimum water droplet size of 10-15 Ám is required for effective separation. The speed of centrifuge 10 can be varied depending on the amount of water (10% to 90%) to be separated from the oil/water mixture. A re-injection pump 12 may also be included to return the separated water to the oil source. The separated solids may be returned with the water or they may be transported to the surface with the separated oil.

Title: Method for fabricating low-loss optically active device
Inventor: YOU BYONG-GWON
IPC: G02B6/12
Filed: 1998-02-26
Abstract: A method of fabricating a low-loss optically active device having an optical waveguide the core 140 of which is formed from a optically linear polymer except for one section 150 which is formed from a optically non-linear polymer. An optically transparent lower clad layer 170 is formed on a substrate 100. A layer of optically linear polymer coats the lower clad layer and has refractive index greater than the latter. A metal layer is formed upon the said layer of linear polymer over those regions where the linear sections of the waveguide are to be formed. Etching removes the uncovered section of the linear polymer leaving a space which is then (almost) filled with non-linear polymer. The first metal layer is removed ad a second is formed over those areas of the linear/non-linear polymer which will form the complete waveguide. Etching removes the extraneous non-waveguide areas leaving a waveguide structure (140 and 150) comprising linear and non-linear regions. An upper clad layer is formed over this waveguide using material of a refractive index lower than that of the waveguide.

Title: Method of manufacturing silicon hemispherical grains
Inventor: WATANABE HIROHITO
IPC: H01L21/8242
Filed: 1998-07-14
Abstract: Silicon crystal nuclei are formed on an amorphous silicon layer surface in a silicon-containing gas, eg silane, atmosphere at a temperature of around 560‹C. The wafer is then annealed in vacuum, or in an inert gas atmosphere, for a predetermined time to form hemispherical silicon grains (HSGs) around the nuclei. The grains are formed by the surface migration of silicon atoms from the amorphous layer towards the nuclei. A gas, eg O 2 , N 2 O, O 3 , for preventing the surface migration of the silicon atoms is supplied upon completion of annealing, thereby stopping HSG growth. By stopping HSG growth before removal of many wafers from the anneal chamber the size and shape of the HSGs on each wafer can be made more uniform. The hemispherical grains are used ti increase the surface area of a capacitor electrode used in a DRAM.

Title: Channel characteristic estimation for intersymbol interference reduction using reliable symbols
Inventor: RIESS EILON
IPC: H04L25/02
Filed: 1999-11-04
Abstract: In a multilevel coded signal channel subject to intersymbol interference (ISI), such as a QAM system with a high order constellation, the receiver extracts 'reliable symbols' from the symbols received. Reliable symbols <B>60</B> are those which are closer to their received constellation points <B>30-42</B> and <B>46-58</B>, that is their transmitted constellation points scaled by the channel gain but free from ISI noise effects, than to any other constellation points. These extracted 'reliable symbols' are used to evaluate the channel characteristics, which may then be used to control a compensating channel filter or equaliser. In the embodiment reliable symbols are identified as those that are preceded and followed by a predetermined number of symbols of relatively lower power, as illustrated in Fig. 3. The system negates the need for special training sequences to be sent to initially determine channel characteristics.

Title: Apparatus for compacting an adhesively bonded nonwoven fabric
IPC: D06C21/00
Filed: 1974-08-20
Abstract: A moistened fibre fleece (11), which contains a thermoplastic binder and which is already preconsolidated, is guided over a rotating drum (12), the outer surface of which is covered with a layer (31) of low-friction material, for example Teflon. This outer surface is heated to a temperature which is higher than the softening temperature of the binder in the fibre fleece. A further adhesive binding of the fibres in the fibre-fleece region guided so as to rest on this outer surface thereby takes place. The drum outer surface is part of a device for compressive shrinkage. This includes an elastic band (16) which partially loops round the drum and against which the running fleece bears. As a result of the contraction of this band, the fleece is also moved by adhesion and at the same time shrunk by longitudinal compression. The fleece thereby slips along the low-friction layer (31) covering the drum outer surface. Simultaneously with the further adhesive binding of the fibres of the fleece, an improved shrinkage takes place, since the drum outer surface opposes only slight resistance to the longitudinal compression of the fleece. <IMAGE>

Title: Distributed load sharing in a communications network
IPC: H04L12/28
Filed: 1988-12-26
Abstract: Methods and apparatus for exchanging frames between bridges distribute load sharing in a communications network. The communications network is of the kind in which bridges, and related stations and local LANs, e.g. Ethernet LANs and 802 LANs, can be linked by paths in a plurality of sub-networks and wherein the bridges are linked to support a Spanning Tree Protocol (STP) which elects one bridge as a root and then with respect to said root, computes and utilizes one and only one loop-free set of primary paths between all bridges. Remaining paths, i.e. paths other than said STP primary paths, between the bridges are examined as possible sub-network paths for a Distributed Load Sharing (DLS) configuration in which frames exchanged between certain stations can utilize more than the STP one set of primary paths. Certain ones of the remaining paths are selected as DLS paths under certain conditions and frames are routed over a selected DLS path only when those frames meet certain criteria.
