Abstract: Particle loading assembly and method for loading particles into a vessel to form a densely packed particle bed comprising an inner layer of particles and an outer layer of particles. The inner layer of particles is arranged radially and concentric with the outer layer of particles. The inner layer of particles contains at least a first type of particle of different granulometry or range of composition or both granulometry and range of composition from a second type of particles contained in the outer layer.

Abstract: A radial U-flow adsorption unit for air purification in a TSA process, having a gas outlet at one end and at least one gas inlet at the side, preferably at the same end of the unit as the gas outlet. The simpler design of the unit facilitates manufacture, installation and transport, and reduces the capital and operating costs.

Abstract: An adsorber vessel for the adsorption of gas contaminants from a gaseous stream comprising a vertical wall baffle positioned on an inner surface of an absorber vessel wall, and a bed support positioned below the vertical wall baffle and affixed to the inner surface of the adsorber vessel wall to support an adsorbent material, where the adsorbent material is interned by the bed support, the adsorber vessel wall, and the vertical wall baffle such that at least 90% of the volume created between the vertical wall baffle and the inner surface of the adsorber vessel is free of the adsorbent material.

Abstract: An adsorbent vessel and process for using the adsorbent vessel subject to thermal swing expansion/contraction is disclosed where the adsorbent vessel comprises a support screen affixed to the adsorption vessel subject to thermal swing expansion/contraction and where a first section of the support screen extends along a portion of the length of the adsorption vessel subject to thermal swing expansion/contraction in the axial direction and comprises apertures permitting gas permeation and where the first section of the support screen has a cross-section in the axial direction that is arcuate.

Abstract: An apparatus for the cryogenic distillation of air includes an assembled unit that has a first distillation column module within which is provided a cryogenic distillation column; a heat exchange module within which is provided heat exchange means for cooling column feed air to a cryogenic distillation temperature; and at least one further processing unit. The or each distillation column, the heat exchange means, and the or each further processing unit are operationally interconnected, and the assembled unit is suitable for transportation to and erection at the site for a cryogenic air separation plant. Construction of a cryogenic air distillation plant is simplified resulting in a reduction in construction cost and time of construction. In addition, as components of the apparatus are self-contained within modules, the risk of contamination of the internal components is reduced, thus improving control of the quality of the construction.

Abstract: An apparatus for generating graphics is connectable in a computer system between a system processor and a system memory by way of a data bus. The apparatus comprises two registers for the storage of X and Y coordinates respectively of a single pixel. The coordinates are applied to an address conversion calculation unit for calculating a linear memory address corresponding to the pixel coordinates and the data representative of the pixel is stored in the system memory at the calculated address. The two registers are memory mapped to appear at two or more locations in memory such that operation of the apparatus is dependent on the memory location used by each register. The apparatus carries out many of the repetitive operations required in the generation of graphics.

Abstract: A data processing system comprising a block move engine, a memory, a register and a reader. The block move engine may be configured to process data. The memory may be configured to store data in the form of a linked list comprising a plurality of items of control data. The register may be associated with the block move engine and configured to control the block move engine, in response to the control data. The reader may be configured to read the control data from the memory and apply the control data to the register.
