摘要： A compact, on-axis telephoto lens camera includes an arrangement of mirrors which receives incident light, and compresses and redirects the light, the arrangement having a primary mirror which receives the incident light, compresses and redirects the light toward a focal point of the primary mirror and has an opening defined at a central portion thereof, and a secondary mirror which receives light from the primary mirror and further redirects same. The camera also includes a cavity which extends into the camera from the opening of the primary mirror, aspheric lenses disposed at least partially within the cavity which receive the light from the multiple-mirror arrangement, and progressively expand and redirect the light received from the mirror arrangement, and an image sensor which receives the light from the aspheric lenses. The image sensor is disposed closely adjacent to the cavity such that a back focal length is substantially zero.

摘要： An optical cloaking system which optically cloaks/hides an object in the visible light spectrum such that the object appears invisible, while permitting a background behind the object to be viewed substantially without distortion. The system includes at least one optical device manufactured using common optical materials in the form of prisms, lenses, mirrors, and the like, which is placed between an observer an the object to be cloaked, and the optical device bends and/or compresses light such that the light passes around a cloaked space in which an object is disposed, and the observer viewing a larger space including the cloaked space will not see the object, but will see a background behind the object in full view substantially undistorted in relation to the rest of the larger space.

摘要： The object of the present invention is to provide a catalyst regeneration process which can improve catalyst selectivity. A first aspect of the invention is characterized in that a spent catalyst from a reactor is introduced into a first fluidized bed regenerator and contacted with an oxygen-containing gas stream and optional steam to carry out a coke combustion reaction, wherein the resultant mixture of the partially regenerated catalyst and flue gas is introduced into a second fluidized bed regenerator and contacted with steam and an optional oxygen-containing gas stream to carry out a further regeneration reaction, and then the regenerated catalyst is introduced into the reactor. A second aspect of the invention is characterized in that a spent catalyst from a reactor is introduced into a fluidized dense bed regenerator and contacted with an oxygen-containing gas stream and steam to carry out a coke combustion reaction, and then the regenerated catalyst is introduced into the reactor. The inventive processes result in a more uniform distribution of the regenerated catalyst activity; due to the exposure of the catalyst to a low temperature for a long time, a part of the heavy metals are buried by the matrix and the remaining are passivated. Thereby dry gas and coke yields decrease sharply when hydrocarbons are subjected to a catalytic cracking reaction on the regenerated catalyst.

摘要： A rail gun launcher consists of an armature where a magnetic core with a multiple turn conductive coil, two parallel conductive rails on which terminals of the coil contact and slide, and a non-magnetic conductive barrel enclosing the rails and the armature. The coil partially encloses the magnetic core to shift magnetic equilibrium. When an AC power source is connected to the rails, the coil generates a source magnetism around the coil as well as an induced magnetism on the conductive barrel in an opposite direction through the magnetic core. The source magnetism and the induced magnetism are shifted in magnetic equilibrium and in opposite direction thereby repelling the armature forward. This repulsive force travels with the armature and is continuous from breech to muzzle and propels the armature forward to a high velocity without control circuitry or commutation.

摘要： This invention discloses a bend insensitive single mode fiber, which is composed by a bare glass fiber with a round cross section and two resin protective layers with circular cross sections surrounding the outer of the bare glass fiber. It is characterized in that the bare glass fiber is composed by a core layer with a round cross section and two claddings with circular cross sections. The refractive index of the core layer is higher than the index of the two claddings and the refractive index difference between the core layer and the first cladding is larger than the difference between the first and second claddings. The second cladding is made of pure SiO2. The refractive index profile of the core layer follows a power function, and the refractive index profile of the two claddings follow a ladder-type distribution. The loss of the invented fiber is insensitive to the bending of the fiber, which meets the requirements of ITU.T G.657.A and G.657.B standards, respectively. It is applicable to the Fiber To The Home (FTTH) and other local area network and the access network systems.
