Abstract:
The present invention provides plasmonic crystals comprising three-dimensional and quasi comprising three-dimensional distributions of metallic or semiconducting films, including multi-layered crystal structures comprising nanostructured films and film arrays. Plasmonic crystals of the present invention include precisely registered and deterministically selected nonplanar crystal geometries and spatial distributions providing highly coupled, localized plasmonic responses in thin film elements and/or nanostructures of the crystal. Coupling of plasmonic responses provided by three-dimensional and quasi-three dimensional plasmonic crystal geometries and structures of the present invention generates enhanced local plasmonic field distributions useful for detecting small changes in the composition of an external dielectric environment proximate to a sensing surface of the plasmonic crystal. Plasmonic crystal structures of the present invention are also useful for providing highly localized excitation and/or imaging of fluorophores proximate to the crystal surface.
Abstract:
Apparatus for powering devices, comprising a power supply having inputs from two or more different power sources; means for combining the power sources and providing a power supply to one or more end devices; means for comparing the two input power sources and generating an index representative of the relative proportions of each at any time and means for using the index to determine how the power is utilised.

Abstract:
A fluid resistant plastics zip (202) for use on wet suits, wet weather clothing, bags, safety wear and sports equipment plastics zip for clothing capable of providing longitudinal stretchability has two mutually engagable zip tracks (203, 204). A slotted female zip track (204) is capable of merging with a complementary male zip track (203) within a slider (215). The female and male elongate zip tracks each being of constant and complementary cross section (205, 206) so that the male profile fits within the female profile when merged to provide a fluid barrier across the zip when the zip is closed.
Abstract:
The present invention is directed to articles comprising smudge-resistant anti-reflective surfaces, and products and devices comprising the articles.

A plastics zip for clothing capable of providing longitudinal stretchability has two mutually engagable zip tracks (203, 204). A slotted female zip track (204) is capable of merging with a complementary male zip track (203) within a slider (215). The female and male elongate zip tracks each being of constant but different cross section in identical segments separated by gaps along a tape to enhance flexibility and stretchability of the zip
Abstract:
A zip end stop for a jacket type zip has a pin box 161 attached to the bottom end of a female zip track 104 and has a rebate 165 or recess for the purposes of receiving a resilient latch attached to the bottom end of a tape or flange attached to the male zip track 103. When engaged the latch will be securely held in the rebate and resists longitudinal movement of the male profile relative to the female profile.
Abstract:
A plastics zip for clothing has two mutually engagable male (203) and female (204) zip profiles of generally uniform cross section along the whole or part of their length and merged or demerged within a special slider (115). The slider has two guide slots (116, 117) which join to create a Y-shaped passageway within the body of the slider and side slits (118, 119) to allow the slider to move along the fixed tapes or flanges (108, 109) of the zip profiles. One of the guide slots contains an expansion element (226) which opens the jaws of the female profile allowing it pass over and capture the smaller male profile so that the zip is merged. Movement of the slider in the opposite direction allows the two profiles to be demerged and exit from the slider.
Abstract:
A replaceable shim (28) is provided for a planetary gear arrangement (10) of the type having planetary gears (20) each of which is rotatably mounted to a frame (12) by a shaft (18). The shim (28) includes an elongated flat body (30) having a generally U-shaped recess (32) at one end and which is adapted to be inserted in between the planetary gear (20) and the frame (16) so that the shaft (18) is positioned within the U-shaped recess (32). The opposite end of the shim is then pivotal to a position in which the opposite end (36) abuts against a portion of the frame (24) thus locking the shaft in the U-shaped recess on the shim body. A bendable locking tab (40) is then bent to a position in which the bending tab abuts against a second surface (44) on the frame and prevents further pivoting of the shim. In doing so, the bending tab (40) locks the shim to the frame with the planetary gear shaft (18) positioned within the shim recess.
Abstract:
The present invention is a method of producing a lanthanum carbonate hydroxide or lanthanum oxycarbonate which has improved properties. The method involves the use of a water soluble lanthanum and a water soluble non-alkali metal carbonate or bicarbonate. The resulting material can be used as a phosphate binder individually or for treating patients with hyperphosphatemia.
