A color shifting interference structure is provided. The color shifting interference structure comprises: a magnetic layer, a reflector layer, a dielectric layer over the reflector layer, and an absorber layer over the dielectric layer. The interference structure exhibits a color shift such that the interference structure has a first color at a first angle of incident light or viewing and a second color different from the first color at a second angle of incident light or viewing. The interference structure further comprises an insulator layer over the magnetic layer and the reflector layer is disposed over the insulator layer. The insulator layer has a thickness for preventing corrosion of the interference structure.

An amusement ride (10) involving riders (17) being conveyed through the air. The amusement ride (10) comprises a tower (11) having a column (23) of framework construction, typically of a height of at least 30 metres. A hub structure (33) is supported on the column (23) for rotation with respect thereto and for displacement therealong. A first drive means (51) is provided for rotating the hub structure (33) with respect to the column (23). A second drive means (61) is provided for displacing the hub structure (33) along the column (23). Rider carriers (81) are suspended from the hub structure (33) to undergo motion in response to movement of the hub structure (33) with respect to the column (23), involving the riders (17) being conveyed along a path around the column (23), with the elevation of the riders changing during the ride through displacement of the hub structure (33) along the column (23). The amusement ride (10) is of a design which is conducive to construction on a large scale.

Mounting apparatus for gates used in association with scaffolding comprises means for cooperating with a known scaffold fixing system, a hinge and means for attachment to a gate (7). The apparatus may be adapted for in either the Cuplok or Kwikstage systems. A method for reclaiming damaged scaffolding comprises the steps of truncating the tubular component (1) to produce a relatively long portion and an end portion (4). The end portion (4) may be used as part of mounting apparatus in association with scaffolding.

An apparatus and a method are described for facilitating the fabrication of a closing spool for installation between two pipe end sections. The apparatus comprises a positional offset measurement instrument suitable for connecting to, and determining the spatial relationship between, two end cap flanges of the pipes. In an alternative embodiment the apparatus further comprises a centre finder flange suitable for connecting a flexible arm of the instrument to an open flanged pipe. A simulation rig is also described which allows for the positional offset measurement instrument to reproduce the recorded measurement data at a location suitable for fabrication of the closing spool. Thereafter, the positional offset measurement instrument can test and verify the dimensions of the closing spool such that these dimensions can be confirmed to lie within predetermined tolerance levels.

A method and an apparatus for authenticating communication of a client (110) to a content server (120). A ticket authority (225) generates a ticket associated with the client (110). The ticket comprises a first ticket and a second ticket. The ticket authority (225) transmits the first ticket to the client (110) and the client (110) uses the first ticket to establish a communication session (135) with a content server proxy (115). The ticket authority (225) then transmits a second ticket to the content server proxy (115) and the content server proxy (115) uses the second ticket to establish a communication session (145) with the content server (120).
摘要:
Disclosed are methods and materials for preparing metal matrix composite (MMC) components that have low weight, good thermal conductivity and a controllable in-plane coefficient of thermal expansion. One embodiment of the invention features a metal matrix composite that includes a metal alloy and random in-plane discontinuous fibers. In some embodiments, the metal alloy includes aluminum, copper or magnesium. In certain embodiments, the metal matrix composite includes additives that enable solution hardening. In other embodiments, the metal matrix composite includes additives that enable precipitation hardening. Another embodiment of the invention features a method of manufacturing a metal matrix composite. The method includes contacting random in-plane discontinuous fibers with a binder, and pressurizing the random in-plane discontinuous fibers and the binder to form a bound preform. The preform is pressurized to a pressure greater than the molten metal capillary breakthrough pressure of the bound preform. Subsequently, the bound preform is placed in a mold, infiltrated with a molten infiltrant, and the molten toform infiltrant is cooled the metal matrix composite.
摘要:
A delivery system for placement of a stent within a body of a patient includes a stent, a retaining structure, and an elongated member. The stent includes a coil which defines a lumen and has an initial length when in an expanded rest state. Adjacent turns of the coil are positioned to substantially prevent tissue ingrowth through the turns and into the lumen when the stent is placed within the body. The retaining structure is sized for insertion into the body and includes one or more pins. The pins collapse and deform the stent while the stent maintains substantially its initial length. The elongated member is coupled to the retaining structure and enables insertion of the retaining structure with the stent into the body such that the stent can be deployed from the retaining structure and placed into the body while maintaining substantially its initial length.

A substance distribution apparatus has a receiver for receiving a signal containing at least a substance component. The apparatus further has a substance generator for producing a plurality of desired substances. A processor communicates with the receiver and the substance generator to interpret the desired substance signal and causes the substance generator to generate and release selected of the desired substances which correspond to the desired substance signal. The apparatus may further include tactil features such as a water mist generator and temperature regulation.
