    摘要: A solar energy collector system which includes n groups (13, 14) of arrayed reflectors (15) and n 1 target receiver systems (10, 11, 12) which present absorbing surfaces to solar radiation that is reflected by the reflectors (15) within the groups. The receiver systems (10, 11, 12) are elevated relative to the reflectors (15) and the reflectors are pivotally mounted to support structure (19) in a manner such that they may be positioned angularly to reflect incident radiation toward one or the other of the receiver systems (10, 11, 12). The collector system is characterized in that at least some of the reflectors (15) within each group (13, 14) are arranged to be pivoted to an extent such that they may be oriented selectively to shift the direction of reflected incident soar radiation form one to another of the receiver systems.

    摘要: A method for moulding multiple castings in which each mould is fed from a source of molten metal through a thin slit the width of which lies in the range 1.25 mm down to 0.25 mm. The cast articles can easily be removed from the runner and riser system after casting without a machining operation so that the casting moulds can be packed closer together and more castings can be produced from each mould assembly. The thin slit also acts as a filter. A particular mould assembly seen in FIG. 2 is cylindrical and comprises a plurality of wedge-shaped mould segments 2 having mould cavities 4 in abutting faces. A central runner passage 6 is formed when the mould segments are assembled and the metal flows into the mould cavities through narrow slits 10 in one edge of each mould. After casting and removal of the mould the narrow flashing formed in the slits can easily be broken to remove the cast articles from the metal formed in the central runner passage.

    摘要: In Titanium casting the surface of the casting is usually contaminated with a brittle oxide layer which has to be removed. Physical or chemical machining reduces the dimensions of the casting and adds to its cost. Chemical reagents may remove fine surface detail.In accordance with the invention the oxygen in the oxide layer is removed by contacting the surface of the casting with an oxide scavenge agent, notably Titanium, for a sufficient time and at a sufficient temperature to allow diffusion of the oxygen from the surface into the scavenge agent.

    摘要: In a process for making refractory articles, such as cores and moulds for use in casting metals, the articles are formed from dies using a refractory material mixed with a thermosetting resin. The articles are formed with the mixture heated to a softened state and the resin is cured. Thereafter the article has to be fired and problems have arisen with deformation of the articles during the firing process.With the present invention, the articles, 8, which as can be seen in FIG. 2 are mould segments, are bound into an assembly with a flexible refractory tape (15) which shrinks on firing to a greater extent than the articles, and thus pulls the assembly tightly together whereby each article provides support for the adjacent article and prevents distortion. The joint faces between the mould segments are thus held in tight abutment and for pouring metal into the mould, the firing cup is fitted and a coating of refractory slurry is brushed on without removing the tape to seal the assembly.The process is also applicable to the manufacture of cores to prevent bending during firing.

    摘要: An augmented ceramic composite including aluminosilicate nanotubes may be added to a biocompatible polymer matrix. Aluminosilicate nanotubes have a surprisingly high biocompatibility, radio opaqueness, and suitability for storing therapeutic compounds for release over time. These surprising advantages make aluminosilicate nanotubes, such as halloysite nanotubes, a good candidate for use in various medical applications from bone and dental prosthetics to cancer treatment and prevention. Furthermore, unlike other additives, the addition of certain quantities of halloysite nanotubes increases the strength of the polymer matrix to which it is added.
