    摘要： A method for the preparation of a two-phase magnetic material comprising as the major phase a crystalline alloy of one or more rare earth metals, boron and iron, substantially all of the crystallites of which have a size of less than 35 nanometres, and as the minor phase (alpha)-Fe, which method comprises the steps of (i) melt spinning an alloy consisting of up to 12 atomic percent of one or more rare earth metals, 3 to 7 atomic percent of boron and the balance iron or a mixture of iron and cobalt; (ii) quenching the melt spun alloy from step (i) under conditions such that a mixture of crystalline and amorphous material is produced, (iii) subjecting the material from step (ii) to an annealing treatment under conditions such that controlled crystal growth occurs to provide the crystalline alloy phase, substantially all of which has a particle size of less than 35 nanometres, the resulting materials having a remanence in excess of the theoretical value of 0.8 Tesla.

    摘要： A retroreflecting means has for its objective to provide a simple and inexpensive means thereby to avoid the need for such expensive means as triple screen mirrors or corner cube reflectors, and yet provide a degree of clarity of a reflected image or a degree of accuracy in the retroreflective direction previously obtainable only when employing such expensive means. The objective is met by a construction comprising a fine pitch retroreflective sheet (2) overlaid by an array of optical lenses (5).

    摘要： A method of forming a metal component comprising at least one bulk volume and at least one surface layer. The method comprises: a) depositing a layer of metal powder onto a substrate; b) using a laser array to melt and fuse a first portion of the layer of metal powder; c) using one or more galvanometer mirror deflected lasers to melt and fuse a second portion of the layer of metal powder. The actions in b) and/or c) also fuses said first portion to said second portion. The second portion of the layer of metal powder is the portion which will comprise a surface layer of the finished component. The invention further includes an apparatus capable of performing the method of forming a metal component, a kit for upgrading an existing apparatus to perform the method of forming a metal component and a metal component formed from said method.

    摘要： The present invention relates to a heterotrophic methods of culturing algae, particularly Galdieria species, to produce the valuable pigment phycocyanin. The methods rely on high oxygen saturation and controlled base dosing to provide improved phycocyanin production. The present invention further relates to algal biomass, compositions comprising said biomass or phycocyanin, uses thereof in various products, and a reactor for culturing the algae.
