Title: Process to extract carbon dioxide from air
Inventor: BENTON DAVID JAMES
IPC: B01D53/22
Filed: 2008-02-28
Abstract: A process where the carbon dioxide concentration in an air mixture may be increased by means of a gas separation membrane, employing either Knudsen diffusion, molecular sieving, surface diffusion, capillary condensation or a solution diffusion permeation mechanism to produce a product gas which may be used as a feedstock for the production of hydrocarbon fuels. The process enables the extraction of carbon dioxide gas from atmospheric air to produce a final enriched product of gas concentration of >90 v/o, (v/o = volume percent). The process may employ a single membrane module or a cascade comprising a plurality of stages of membrane modules arranged in series with a compressor 4 between each stage and recycling of gas between stages. The membrane stages may be the same or different. A membrane/cascade process may also be used to increase the concentration of the carbon dioxide in the product gas to less than 90 v/o followed by a Pressure Swing Adsorption process to complete the carbon dioxide extraction.

Title: Fuel injection nozzle with nano-sized holes and reduction of fuel viscosity
Inventor: ADAMSON JANUSZ
IPC: F02M31/10
Filed: 2008-10-13
Abstract: A fuel injection nozzle is made of perforated, eg ceramic, material 6 with nano-sized holes that can be universally incorporated in all types of fuel injection systems. The holes may be made by inkjet head technology. The fuel injection nozzle acts as the fuel-dispensing nozzle which atomises the fuel into fine droplets of micro or nano size and injects it directly into the engine's air stream. Reducing droplet size increases fuel droplet area for oxygenation, thus improving fuel combustion, and reducing harmful emissions. Further improvements in fuel combustion are achieved by reducing fuel viscosity eg by MEMS atomisation, electrorheology or using heat from the radiator of the vehicle. The purpose of a car fuel injection system is to deliver fuel, primarily petrol or diesel, into the car engine cylinders, whilst controlling the injection timing, fuel atomisation, air supply, and other parameters, and generate power.

Title: Rendering shadows in augmented reality scenes
Inventor: COOPER RICHARD JARED
IPC: G06T15/50
Filed: 2008-11-28
Abstract: Video signals representing a real scene are processed to combine a computer generated object with the video signals with the effect that the object appears within the scene. The scene includes a first real object upon which a virtual model of the real object is mapped (s100) so that the virtual model substantially corresponds with the real object. The virtual model has alterable transparency such that it can be rendered as substantially transparent within the scene. Regions upon the virtual model which are determined to be occluded from a virtual light source by the computer generated object are detected (s105). The occluded regions of the virtual model thereafter have their transparency modified (s110), such that when the scene is rendered (s115), the modified transparency regions appear as shadows upon the object.

Title: Improvements in or relating to the baking of bread
IPC: A21D8/08
Filed: 1950-04-26
Abstract: Heat-hardenable polysilane resins for coating bread-baking tins and containing both phenyl and methyl groups are made by reacting an organo silicon chloride or mixture of two or more such chlorides having the formula or average formula (CH3)n(C6H5)mSiCl4-n-m, where n+m has a value of 1.2 to 2 and m/n+m has a value of 0.2 to 0.7, with an alkali metal.  The metal is preferably in finely-divided form, e.g. wire, small pieces, or dispersed in molten or solid form in a liquid hydrocarbon.  When a mixture of silanes is used, each should preferably contain a phenyl group.  The reaction may be performed under reflux at 50-200 DEG  C.  The starting silanes may be chosen from silanes having the formula (CH3)x(C6H5)ySiCl4-x-y, where x+y are 0, 1, 2 or 3 and (4-x-y) is not less than 1.  Eleven examples of starting materials are given.  The resin product is separated from residual alkali metal and salt by-product and dissolved in a solvent such as benzene toluene, xylene, carbon tetrachloride or methylene or ethylene chloride.  The solution may then be applied to clean bread pans, air-dried for 30-60 minutes and baked at 400-500 DEG  F. to harden the resin.  Alternatively the resin may be hardened during the bread baking.  The curing may be assisted by a catalyst such as tertiary butyl, or lauryl, peroxide.  The coated pans give a perfect release over more than 250 baking cycles.  Specification 675,057 is referred to.
