Patent number: 6824696Abstract: An oil from water separator has an oil disengagement chamber adapted to receive an oil and water mixture and retain it for a sufficient time in a relatively undisturbed state so that oil in the mixture floats to the top of the mixture. This results in a substantially oil free volume of water having a layer of oil derived from said oil and water mixture floating on the surface of the mixture. The oil disengagement chamber is partially separated from an effluent water chamber by an under flow baffle which ducts said substantially oil free volume of water to the effluent water chamber. The oil disengagement chamber has a low liquid level which is higher than the under flow baffle. The outflow of the substantially oil free volume of water from the effluent water chamber is limited to a rate of outflow which is a function of the head of the liquid in the effluent water chamber.Type: GrantFiled: February 22, 2000Date of Patent: November 30, 2004Assignee: Unisearch LimitedInventors: David Bleasdale Tolmie, Phineas Balantyne Stone

Patent number: 6821875Abstract: In a method for forming a contact on semiconductor surface, a crystalline silicon surface is first oxidized, following which an aluminium layer is deposited onto the oxide layer. A layer of amorphous silicon is then deposited onto the aluminium layer. The structure is then heated to a temperature below the aluminium/silicon eutectic temperature to locally reduce the oxide layer in regions where the quality/density of the oxide layer is lower. Simultaneously, the amorphous silicon penetrates into the aluminium layer, in which it has a high mobility. With continued heating, the aluminium penetrates completely through the oxide layer in localized regions, exposing the crystalline silicon surface. The exposed silicon surface provides a sight for nucleating epitaxial growth, which occurs rapidly as silicon within the aluminium continuously feeds the solid phase epitaxial growth process.Type: GrantFiled: November 5, 2002Date of Patent: November 23, 2004Assignee: Unisearch LimitedInventors: Stuart Ross Wenham, Linda Mary Koschier

Patent number: 6808743Abstract: The present invention relates to a method of growing a ZnO film using chemical vapour deposition (CVD), and to a ZnO film grown according to the method. The method includes providing a precursor in vapour form, the precursor substantially comprising Zn4O(O2CNRARB)6, where RA and RB are any combination of akyl or perfluoroalkyl groups, and decomposing at least some of the vapour at the surface of the substrate such that the film of zinc oxide forms. An advantage of using this precursor material is that, unlike in the prior art, no deliberate introduction of water vapour to improve christallographic orientation is required. Higher purities in oxide films are produced.Type: GrantFiled: April 9, 2003Date of Patent: October 26, 2004Assignee: Unisearch LimitedInventors: Antonella Julie Petrella, Robert Norman Lamb, Nicholas Kenneth Roberts

Patent number: 6760482Abstract: A method for lossy compression of images reduces visual distortion for a given compressed bit-rate or, equivalently, requires a lower bit-rate for a given level of visual distortion. An image is decomposed using a space-frequency transform and frequency bands are then partitioned into small blocks. The blocks are independently quantized and coded using an embedded block coder, so that each block bit-stream contains a large number of finely spaced truncation points. A visual distortion measure is computed for each block at each truncation point, where the metric is sensitive to masking properties of the Human Visual System. The distortion values and bit-stream lengths corresponding to each block's truncation point are used to optimise overall visual distortion at one or more target bit-rates or to minimise the bit-rate corresponding to one or more target visual distortion levels.Type: GrantFiled: March 1, 2002Date of Patent: July 6, 2004Assignee: Unisearch LimitedInventor: David Scott Taubman

Patent number: 6743467Abstract: A method is provided for forming a modified gel capable of forming a hydrophobic surface on which water has a contact angle of at least 150°. Additionally, a method is provided for forming a hydrophobic coating from the modified gel. In some embodiments, the hydrophobic coating has an extremely high hydrophobicity with a contact angle in excess of 165°, and good substrate adhesion. The method involves bonding a gel with particulate matter. It is believed that the chemical hydrophobicity of the gel is enhanced by the physical roughness of the particulate matter.Type: GrantFiled: May 1, 2002Date of Patent: June 1, 2004Assignee: Unisearch LimitedInventors: Ashley Jones, Robert Norman Lamb, Hua Zhang
