    摘要: Powders having contact biocidal properties comprise a polysaccharide carrying atomic/metallic silver. The preferred polysaccharide is chitin, although other polysaccharides including chitosan, carboxymethyl celluloses and carrageenans can be used. The chitin may be obtained from deproteinated crustacean shells without demineralisation, thus being admixed with calcium carbonate and other naturally occurring minerals present in the shells, and may be enzyme deacetylated. The powders of the invention can be used as biocidal dusting powders, formulated into pastes, gels, hydrogels, creams, foams and aerosol sprays for pharmaceutical applications, or dissolved to form solutions for coating substrates such as skin, fabrics, glass, leather and paper to give a bactericidal surface. A particular application of such a solution is as a protective, post-wash treatment for workwear in a laundering process. The powders of the invention may be prepared by slurrying a polysaccharide, which is capable of interacting with silver ions and which is in powder form, in a liquid in which the polymer is insoluble, which liquid contains silver ions, filtering off the powder, washing the powder, reducing the silver ions which have interacted with the polysaccharide to atomic/metallic silver, and drying the powder. According to the polysaccharide chosen, the liquid is suitably water or aqueous ethanol. The silver ions may derive from silver nitrate. The reduction of the silver ions which have interacted with the polysaccharide to atomic/metallic silver can be effected photochemically through exposure to light. To hasten the reduction, however, the washed powder is preferably slurried in a solution of an alkali metal halide, irradiated under stirring with natural or artificial light containing an ultraviolet component, and again filtered off and washed, before drying it.

    摘要: In a process for the preparation of an article having a contact biocidal property, there is provided a polymer solution which contains atomic/metallic silver in suspension or complexed with the polymer and/or which contains a silver compound in solution, in suspension or complexed with the polymer. This polymer solution is applied to a substrate by impregnation or surface deposition, thus coating the substrate. Alternatively, it is possible to convert the polymer solution to a fibre, film, powder or foam, effectively forming the article from the polymer solution instead of coating an existing article. In either case, any silver compound present is reduced to atomic/metallic silver, and the resultant article is dried.Chitosan is preferably used as the polymer, although poly(vinyl alcohol) and sodium alginate can also be used. The polymer may be cross-linked at a suitable point in the process to insolubilize it.

    摘要: A joining member for bridging a gap between a first and at least one second panel wherein the joining member comprises a flange member, one or more extension members extending from the flange member, and at least one retaining member connected to the extension member. The retaining member is moveable relative to the extension member between a first configuration and a second configuration, the retaining member in the second configuration being insertable in use through the gap between the first and at the least one second panel. When inserted through the gap, the retaining member is engageable with a rear surface, relative to the flange member, of each panel and the flange member substantially bridges the gap between the first and second panels.

    摘要: A system and method for improving performance and fuel efficiency of a combustion engine by providing an oxygen enriched gel which is inserted near an air intake, where the gel is stored within a container formed from a gas permeable membrane which is sufficiently porous so as to enable the gel to gradually evaporate. The evaporating gel releases oxygen, which is drawn into the air intake, resulting in reduced emissions and improved performance of the engine. No modifications to the combustion engine are required to use the system. The gel is inexpensive, and the gel container is preferably replaced or refilled approximately as often as an oil change is performed.

    摘要: In order to optimize the utilization of resources (e.g., technicians) in performing a number of jobs, each job is assigned a cost time-dependent function and each resource is assessed for the time at which it will be available. For each combination of jobs with resources, an actual can be determined. The combination giving the lowest overall cost is then determined. Additional features are disclosed to ensure incompatible job/resource combinations are not allocated, and to reduce the complexity of the calculation by prioritizing the jobs and resources.
