Abstract: The uniform distribution of mixed phase fluid stream on to the top of a contact bed (18) in a reactor chamber (10) is provided by a horizontal tray (22) with a plurality of spaced-apart vertically disposed chimneys (24) extending through the tray (22). These chimneys (24) have a first end to receive liquid and gas above the tray and a second end (30) for distributing the liquid and gas downwardly below the tray. Importantly, the second end is provided with a spray generating device (23) located below the tray (12) for producing a conical downward spray of the mixed fluid phase onto the top surface of a bed of contact material positioned below the tray (22). The spray generating devices (23) for producing the conical spray are located at positions so that the spray of the mixed fluid stream from one spray generating device as it impinges on the top surface of the fixed bed (18), will overlap the spray from an adjacent spray generating device (23).

Abstract: The invention concerns a certain class of polymers, their production into fi lms and applications for their use. These polymers have unique properties which make them particularly well suited for use in polyme ric films. These films are very useful in applications requiring heat sealability, particularly those applications containing an ionomer fil m. It has been discovered that polymers derived from met allocene catalyst systems surprisingly heat seal extremely well, as compared to polym er produced by conventional Ziegler-Natta catalysts, to a class of polymers known as ionomers.

Abstract: A radiotherapy appliance having controllable radiation beam(s) which converge on a focus volume wherein an object being irradiated can be movably positioned relative to the focus volume for varying time periods and with varying radiation exposure rates, optimally under control of a computer. The computer controls the focus volume radiation beam size, intensity and exposure time for subareas of the treatment target in response to a radiation dose distribution determined for the treatment target. A determination of the radiation beam size, intensity and dwell time of the focus volume in the target area, is made by initially dividing up the specified treatment area into volume elements or voxels and having biological characteristics of the treatment area assigned to each voxel. The energy deposition incident to each voxel to provide this biological characteristic is then calculated. Finally, from the energy deposition incident on each voxel, the dwell time of the focus volume at particular voxels can be determined. Once the dwell time has been determined, the computer generates a sequence of motor control movements to move the patient with respect to the focus volume such that the focus volume is at a position sufficiently long within the treatment target to deliver the necessary radiation for each voxel.

Title: Counterflow drum mixer for making asphaltic concrete and methods of operation
Inventor: BUTLER THEODORE G
IPC: F26B11/04
Filed: 1997-07-22
Granted: 2005-04-05
Abstract: The counterflow drum mixer includes an elevated virgin aggregate inlet end and an opposite asphaltic product discharge end. A burner lies intermediate the ends and defines a combustion volume. Shield flights surround the combustion volume defining an annular chamber with the drum wall. Recycle material is supplied to the annular chamber at the upstream end of the combustion volume for heating by convection and conduction in the annular chamber. The virgin aggregate material flows through a drying zone, into the combustion volume and between the shield flights into the annular chamber for contact with and conductive heating of the recycle material. Radiant heat transfer from the combustion volume along radii of the drum to the annular chamber is prevented. Virgin aggregate and recycle material in the annular chamber is prevented from entering the combustion volume by the shape of the shield flights and the rotation of the drum which enables the virgin aggregate in the combustion volume to shield the recycle material from radiant heat. The combined virgin aggregate and recycle material is mixed with liquid asphalt in the mixing zone to form the asphaltic product.

Abstract: A nickel powder having a composite oxide layer comprising lanthanum and nickel and, optionally an oxide of chromium, on at least a part of the surface thereof. The nickel powder is produced by a process comprising the steps of: bringing a solution comprising at least one heat-decomposable nickel compound and at least one heat-decomposable lanthanum compound and, optionally containing at least one heat-decomposable chromium compound, to fine droplets; and heating the droplets at a temperature above the decomposition temperatures of these compounds to prepare a nickel powder and, at the same time, to deposit a composite oxide layer comprising lanthanum and nickel and, when present, chromium oxide, in the vicinity of the surface of the nickel powder. The nickel powder is suitable for use in a conductor paste to be co-fired with unfired ceramic green sheets for a multilayer component or the like because the sintering initiation of the powder is effectively delayed to around the sintering initiation temperature of the ceramic green sheets, thereby preventing the problems caused due to excessive sintering.

Granted: 2001-08-21
Abstract: In the present invention, an air pipe extends through a stationary blade between outer and inner shrouds.  Further, an air passage is directed to a lower portion of the stationary blade and is communicated with the air pipe so that a serpentine cooling passage is formed.  The air enters a cavity from the air passage and is discharged to a gas passage through an air hole, a passage and a seal.  Thus, the cavity is sealed at a high pressure.  Cooling air is supplied from the air passage to a rotating blade through a cooling air hole, a cooling air chamber, a radial hole and a lower portion of a platform.  The stationary blade is cooled by the air through the air passage.  The cooling air can be supplied to the rotating blade at a low temperature and a high pressure as they are. Accordingly, the air can be also supplied to the rotating blade when a rotor is cooled by vapor.

Title: Method and apparatus for fast image compression
Inventor: PIGEON STEVEN P
IPC: H04N7/30
Filed: 1998-09-24
Granted: 2002-10-22
Abstract: An image compression scheme uses a reversible transform, such as the Discrete Hartley Transform, to efficiently compress and expand image data for storage and retrieval of images in a digital format.  The image data is divided into one or more image sets, each image set representing a rectangular array of pixel data from the image. Each image set is transformed using a reversible transform, such as the Hartley transform, into a set of coefficients which are then quantized and encoded using an entropy coder.  The resultant coded data sets for each of the compressed image sets are then stored for subsequent expansion. Expansion of the stored data back into the image is essentially the reverse of the compression scheme.
