A dental block for producing a dental prosthesis comprises a green body including zirconia and having a chemical composition including increasing amounts of yttria through a thickness of the green body. The green body is substantially opaque with a substantially consistent optical characteristic of non-translucency with respect to visible light across the thickness, and is subsequently millable and sinterable to form the dental prosthesis with an optical characteristic of increasing translucency through a thickness of the dental prosthesis.

A mattress has a main sleep area surrounded by a perimeter trim. Both the main sleep area and the perimeter trim are formed from wire springs contained within pockets of soft material. The wire springs in the sleep area are arranged in honeycomb nested rows. The wire springs of the perimeter trim, which are of different wire construction with different flex characteristic from the wire springs in the main sleep area, are arranged in side by side rows which are not honeycomb nested. In addition, the wire springs of the perimeter trim are pivotally linked directly to one another across the perimeter trim, both widthwise and lengthwise of the mattress which produces an essentially non-feelable flex transition between the perimeter trim and the main sleep area of the mattress.

A system and method for switching data packet traffic distribution across diverse transmission medium according to detected quality of service characteristics for a given data packet rate from server to client. It should be recognized that diverse medium are not interdependent with regard to fading or signal strength considerations. One mode of switching comprises switching all the data packets from transmission on a first medium to transmission over a second diverse medium. In a second mode of switching the distribution is changed according to a media-time coding mechanism in which typically data is being transmitted simultaneously across more than one of the multiple diverse medium. The data packet transmissions preferably comprise audio-video data packet streams, such as MPEG-2 streams. By way of example, the diverse transmission medium may comprise a wireless connection (i.e. WiFi) used in combination with a power-line network connection, such as within a home network.

A flat panel X-ray imager using an amorphous selenium detector which uses a polymer grid structure within the X-ray conversion layer to form an interface between the X-ray conversion layer and the pixel electrodes. The grid structure provides an additional physical barrier between pixel electrodes that reduces electrical bridging due to crystallization of the amorphous selenium due to temperature increases while also reducing the delamination temperature by providing a good anchor to the selenium, as well as a “cushion” for thermal expansion or contraction of the pixel electrodes. The grid can further include one or more grid electrodes for effecting avalanche-gain within the X-ray conversion layer while minimizing dark current entry into the selenium layer from the pixel electrode.

An image pickup apparatus comprising an array of unit cells, vertical signal lines, and a control circuit. The unit cells are arranged in rows and columns. Each unit cell has a light-receiving device for receiving light and generating an electric charge corresponding to the light, a charge-accumulating section for accumulating the electric charge generated by the light-receiving device, a transfer device for transferring the electric charge from the light-receiving device to the charge-accumulating section, and a charge-limiting device for limiting the electric charge accumulated in the charge-accumulating section. The vertical signal lines extend along the columns of unit cells, respectively, each for receiving a electric data item corresponding to the electric charge accumulated in the charge-accumulating section of any unit cell of the associated column. The control circuit controls each of the unit cells, causing the charge-limiting device to limit the charge generated by the light-receiving device during a first period and transferred to the charge-accumulating section through the transfer device. The charge generated by the light-receiving device during a second period following the first period and transferred to the charge-accumulating section through the transfer device is added to the electric charge accumulated in the charge-accumulating section.

Gas oil components, coking process recycle, and heavier hydrocarbons are cracked or coked in the coking vessel by injecting an additive into the vapors of traditional coking processes in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack or coke these components. The quenching effect of the additive can be effectively used to condense the highest boiling point compounds onto the catalyst(s), thereby focusing the catalyst exposure to these target reactants. With a catalyst to crack these highest boiling point materials, this mechanism can effectively increase the catalyst's selectivity, thereby increasing its efficiency and reducing catalyst requirements and costs. Selective, catalytic conversion of the highest boiling point materials in the coking process product vapors (coker recycle and/or ‘heavy tail’ of the heavy coker gas oil) may be accomplished with an exemplary embodiment of the present invention in varying degrees. Exemplary embodiments of the present invention can also provide methods to control the (1) coke crystalline structure and (2) the quantity and quality of volatile combustible materials (VCMs) in the resulting coke. Pet coke from this process may have unique characteristics with substantial utility.

Gas oil components, coking process recycle, and heavier hydrocarbons are cracked or coked in the coking vessel by injecting an additive into the vapors of traditional coking processes in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack or coke these components. Modifications of the catalysts in the additive improve performance for certain desired outcomes. One exemplary embodiment of the present invention uses the olefin production capabilities from newly developed catalysts to increase the production of light olefins (e.g. ethylene, propylenes, butylenes, pentenes) for alkylation process unit feed, the production of oxygenates, and petrochemical feedstocks, such as plastics manufacture. Another exemplary embodiment of the present invention is the use of the olefin production from newly developed catalysts to improve the coker naphtha quality. A third exemplary embodiment of the present invention uses the cracking characteristics of newly developed catalysts to optimize the production of light gas oils, naphtha, and gases from the coking process.

A Lundell type rotor core with a pair of side cores and a magnetic-pole cylindrical portion has a structure in which the magnetic-pole cylindrical portion is mated between both the side cores (also referred to as “pole cores”) in a radial direction at an outside of a field coil wound on a boss portion in the side cores. The magnetic-pole cylindrical portion is made of plural magnetic steel sheets laminated in the axis direction, and is easily deformed rather than both the side cores. The easy deformation characteristic of the magnetic-pole cylindrical portion prevents generation of a gap during the assembling process of the magnetic-pole cylindrical portion and the side cores. Without paying strict dimension control of the components for the rotor core, it is easily possible to prevent any generation of a gap between the side cores and the magnetic-pole cylindrical portion while assembling. It is thereby possible to prevent a deterioration of a magnetic flux flowing in the rotor core.

In accordance with the present invention a mono-wheel vehicle is provided. The vehicle includes a housing with an inner circumference. A wheel is connected to the housing such that the wheel is able to rotate independently of the housing. The wheel has an outside portion that makes contact with a surface. A motor mechanism is provided for rotation of the wheel.

A platform connected to the inner circumference of the housing is pivotable in relation to the housing to causes a change in a center of gravity. The change in center of gravity causes the gyroscopic forces acting on the vehicle to turn the vehicle towards the changing center of gravity in order to maintain the vehicle in a more upright position.
