摘要： Method of extracting dinitrogen pentoxide (N2O5) from its mixture in nitric acid, which consists of providing a solution of the mixture in an inert organic solvent, stripping out the N2O5 from solution in a carrier gas stream containing ozone, and subsequently condensing the N2O5 out of the gas stream by contact with further inert organic solvent. The presence of ozone suppresses the dissociation of the N2O5 transferred to the gas stream into dinitrogen tetroxide (N2O4). In a preferred embodiment the stripping and absorbing steps take place continuously in adjacent stripping and absorbing columns respectively having organic solvent recirculating through each.

摘要： Process for producing dinitrogen pentoxide (N2O5) consists of reacting a solution of dinitrogen tetroxide (N2O4) in a volatile organic solvent, with a stream of an ozone-containing carrier gas. N2O5 produced by reaction between the N2O4 and ozone is transferred into the gas stream, and is thereafter condensed out of the gas stream by contact with further inert organic solvent. The latent heat of formation of N2O5 is absorbed by the heat of vaporisation of the solvent, so limiting increases in reaction temperature and suppressing the dissociation of the N2O5. In a preferred embodiment the reaction and absorption steps are performed in separate columns having organic solvent recirculating continuously through each with carrier gas flowing continuously from the reaction column to the absorption column.

摘要： A two-stage method of producing N2O5 in nitric acid from N2O4 in nitric acid consists of a first production stage in which the anodic oxidation of N2O4 in nitric acid and cathodic reduction of nitric acid are separated by a non-ionic or anionic ion exchange membrane, and a second production phase in which the product of the first stage anodic reaction is subjected to further anodic oxidation, the anodic and cathodic reactions being separated by a cationic ion exchange membrane. The use of a cationic membrane in the second stage promotes, through leakage of N2O4 to the catholyte, an increase in N2O5 concentration and decrease in N2O4 concentration within the anolyte acid whilst avoiding a significant loss of current efficiency. The two stages may be connected in series and operated continuously to produce a nitric acid solution containing typically 32 wt % N2O5 and less than 2 wt % N2O4.

摘要： A method of separating N2O5 from its solution in nitric acid which comprises the steps of: (a) preparing, by the electrochemical oxidation of N2O4 in nitric acid, a nitric acid solution at a temperature of at least 10 °C containing at least 45 wt % of dissolved (N2O4 + N2O5) and having a dissolved N2O5: nitric acid ratio by weight of at least 1:3, and (b) cooling the acid solution to less than 8 °C until an N2O5 solvate precipitates from solution. The main advantage of the invention is that it enables electrically-efficient electrochemical methods to be employed in the production of the acid solution from which the solute is recovered.

摘要： A cross axis actuator (1.1) for reducing the transmission of vibration along elongate members (1.2) comprising a series of windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) wound helically at 30 pitch around the member (1.2) along part of its length in clockwise and anti-clockwise fashion and are anchored at two or more points (1.3, 1.4) to the member (1.2), the windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) being able to be subjected to strain which causes deformation of the member (1.2) between attachment points (1.3, 1.4). The member (1.2) can be either a steel pipe or a rod. The windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) can either be in the form of steel wires or be strips of material. The numbers of windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) wound around the member (1.2) in a clockwise and anti-clockwise direction should be equal. Ideally, the windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) are attached to the member (2) on a continuous basis except for the ends which are left free. The strain is generated from actuators, preferably made from piezo electric materials, which can either be attached to the ends of the windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) or form part of the windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10). The actuators can be controlled by control signals which are calculated by a control unit based on signals produced by vibration sensors (1.13, 1.14). Ideally, part of the member (1.2) is formed to produce an impedance mismatch with the rest of the member (1.2). This can be achieved by having a flexible section (1.2a) within the member (1.2). The windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) are usually attached across this section (1.2a).

摘要： A radiation coupling device (10) incorporates a rectangular multimode beamsplitter waveguide (20) connected at one end to a set of input waveguides (18). The input waveguides (18) have inserted within them respective fibre optic waveguides (22). The input waveguides (18) are connected at periodic positions across the beamsplitter waveguide's transverse cross section. The beamsplitter waveguide (20) is also connected at its other end to retroreflecting mirror (24). Radiation propagating in fundamental mode in any one of the input waveguides (18) passes along the beamsplitter waveguide (20) and is retroreflected at the mirror (24). On return, it becomes divided between the input waveguides (18) by virtue of modal dispersion (multimode interference) in the beamsplitter waveguide (20). The device (10) therefore acts as a star coupler.

摘要： A digital beamforming array for use in radar applications and particularly in radar applications that used phased array technology. The array receives an incoming signal at a plurality of sensor modules, converts them to intermediate frequency, and then converts the intermediate frequency signals to n-bit (preferably 1-bit) digital signals at an oversampling rate, where n is less than the number of bits required to represent the dynamic range of the intermediate frequency signal. The n-bit digital signals are then beamformed by altering their relative phases and combining them to form a resultant n-bit digital signal which is then converted to a digital signal of the number of bits required to represent the dynamic range of the intermediate frequency signal. An advantage of the present invention is that it reduces the complexity and thus the cost of the digitising hardware required.
