摘要:
A method of coating a metallic article having an at least part-metallic surface comprising a first metal, with a surface having a pre-determined wettability, the method at least comprising the steps of: (a) coating at least a part of the metallic article with a layer of a second metal to provide a metal-metal bonded surface, said surface being rough either prior to or because of step (a); and (b) contacting the metal-metal bonded surface of step (a) with a material to provide the surface having the pre-determined wettability. The first metal may be one or more of the group comprising: iron, zinc, copper, tin, nickel and aluminum, and alloys thereof including steel, brass, bronze and nitinol for example. Preferably, the second metal is coated onto the first metal using electroless Galvanic deposition. The nature of the coated metallic article is non-limiting, as the ability of the present invention is to provide a tailored surface with a pre-determined wettability thereon, including superhydrophobic and superhydrophilic wettability. This allows the invention to be capable of application to a wide range of metal types used in different fields.

摘要:
An emergency stopping system for track mounted movable targets used divergent cables to stop a target trolley which has not been otherwise stopped before coming to the end of a track. As the trolley passes over the diverging cables, the cables are forced together, causing the trolley to dissipate kinetic energy.

A lancet has a generally tubular body (1). A hollow insert (4) with a closed end plugs one end of the body (1), and it has a co-axial projection (5) forming a sharp tip proud of that end of the body. The body (1) and insert (4) are simultaneously formed by twin shot moulding, the body being of polyethylene and the insert being of a liquid crystal polymer which will create a sharp tip of adequate strength.

A portable anchorage assembly comprises an extension member interconnecting a counterweight assembly and a base. The counterweight assembly has a cavity configured and arranged to receive at least one weight. The extension member has a first end and a second end. The first end is pivotally connected to the counterweight assembly. The base is connected to the second end of the extension member and includes a wheel and at least one anchorage point. The base is pivotable about the counterweight assembly on the wheel to position the at least one anchorage point in a desired location.

Enabling virtualization in a SAS expander is disclosed. For each SAS address to be virtualized through one or more physical or virtual Phy, a reference Phy associated with each SAS address is created within the expander. Next, a route table is generated that includes an entry for each of the SAS addresses being virtualized, each entry associated with one or more of the physical or virtual Phy through which the SAS address is being virtualized. With the route table so established, requests for a virtualized SAS address are routed to a particular one of the one or more physical or virtual Phy associated with the virtualized SAS address in the route table.
摘要:
A method of forming a solid matrix for use with surface-enhanced Raman spectroscopy is described. The method comprises the steps of: admixing a colloidal metal solution with a polymeric support medium to form a suspension; optionally depositing said suspension on a surface; and then drying the suspension to form the matrix. The polymeric support medium provides a plymer/sol suspension in which the sol particles are resistant to aggregation and precipitation. Upon drying the suspension shrinks to provide a mechanically-hard film subsequently usable to provide a sample for spectroscopic analysis.

A discoidal brushless DC motor having a stator (507) carrying windings (503) arranged in slots which radiate out from the center of the stator to the periphery. The depth of each slot increases towards the center of the stator. The slot, therefore, is wider (from side to side) and shallower towards the periphery of the stator, and narrower (from side to side) and deeper towards the center of the stator. This arrangement ensures that the windings are contained below the surface (504) of the stator (507). The magnetic circuit includes a backing of a ferromagnetic material (509). This ferromagnetic material (509) can be a watch spring core made from a long strip of soft iron tape.
