Abstract: A multi-step process for purifying an immune serum globulin fraction from a crude plasma protein fraction involves precipitating non-serum globulin proteins from an aqueous suspension of the crude plasma protein fraction using a protein precipitant, adding a virus-inactivating agent to the clarified immune serum globulin-containing liquid, absorbing the immune serum globulins onto a cation exchange resin and washing non-serum globulin contaminants from the resin, subjecting the eluate to ultrafiltration to concentrate the immune serum globulins and separate them from low molecular weight species, contacting the concentrate with an anion exchange resin to absorb non-serum globulin contaminants, passing the immune-serum globulins through the anion exchange resin under conditions that leave non-serum globulin contaminants bound to the resin, and subjecting the filtrate to a molecular washing step to produce a purified immune serum globulin fraction. This process results in products substantially free of active viruses and contaminating lipids, activated complements and low molecular weight peptides. In addition, the process is advantageous in terms of efficiency and adaptability to large-scale production.

Abstract: A method for on-line reconstruction of a failed storage unit in a redundant array system. After providing a replacement storage unit for the failed storage unit, reconstruction begins for each data stripe in the array. General reconstruction consists of applying an error-correction operation (such as an XOR operation on data blocks and a corresponding parity block) to the data blocks from the remaining storage units in the redundancy group, and storing the result in the corresponding block of the replacement storage unit. If a Read operation is requested by the CPU for a data block on the replacement storage unit, then a concurrent Read task is executed which reconstructs the stripe containing the requested data block. If a Read operation is requested by the CPU for a data block not on the replacement storage unit, a concurrent Read task is executed which performs a normal Read. If a Write operation is requested for any data block, then a concurrent Write task is executed which performs a Read-Modify-Write sequence in the general case (the Read operation being performed in accordance with the above rules).

An impact tagret (12) is mounted within the grinding chamber (2) and centered on the chamber's central axis (51). Multiple sources (10, 11) of high velocity gas are mounted in the peripheral wall (3) of the grinding chamber (2), are arrayed symmetrically about the central axis (51 ), and are oriented to direct high velocity gas along an axis intersecting the center of the impact target ( 12). 
     There is also described a fluidized bed jet mill in which each of the gas sources has a nozzle holder (10), a nozzle (11) mounted in one end of the holder (10) oriented toward the grinding region, and an annular accelerator tube (15) mounted in line with the nozzle holder (10). The end of the accelerator tube (15) closer to the nozzle (11) is larger in diameter than the nozzle holder (10) and the opposite end (19) of the accelerator tube (15). The accelerator tube (15) the nozzle holder (10) define between them an annular opening (30) through which particulate material in the grinding chamber can enter and be entrained with the flow of gas from the nozzle (11) and accelerated within the accelerator tube (15) to be discharged toward the central axis.

Abstract: An electrical circuit for producing a digital value which is representative of instantaneous phase of an electrical input signal (18) relative to a reference frequency signal (10). The circuit includes a digital counter (12) for continuously generating a stored count representing a value resulting from dividing the reference frequency signal by a repeating count cycle frequency which is of the same order as an expected center frequency of the electrical input signal. A trigger unit (14) produces a trigger pulse in response to the trigger unit receiving a sampling pulse (16) and a transition edge of the electrical input signal. An intermediate register (22) stores a momentary state of the counter circuit (12) in response to receiving the trigger pulse. The momentary state of the counter circuit corresponds to an instantaneous phase value of the electrical input signal. A correcting circuit (23,25) is provided for correcting a resulting numerical value in the intermediate register by removing an accumulating phase offset value. An output register (24) is provided for storing the corrected resulting numerical value of the counter circuit.

Abstract: A resource oriented host computer-printer system is disclosed in which the host computer and printer share information and data processing duties. A system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real-time. The inventive system sends a series of test instructions to the printer at the time the printers is installed on the host computer. A timer is used to time a predetermined period of time during which the draw primitives are sent to the printer for execution. Based on the number of draw primitives executed and the type of draw primitives executed, the system constructs a printer model. A log file is used to store the acquired cost metric data. In one embodiment of the invention, a clumping procedure is used to classify cost metric data. A series of cost tables stores the classified cost metric data. A map table provides a map to the cost table to speed up the process of cost metric data retrieval. At run time, a resource assembler calculates the cost of executing each draw primitive within a band to determine if the printer can render the draw primitive in real-time. If the band is too complex for the printer to render in real-time, the host computer will render the band and transmit the bit-map of that band to the printer. If too many bands on one page are complex, the host computer may render the entire page and transmit the bit-map for all bands on the page.

Abstract: A video signal encoder uses an encoding system such as that developed by the Moving Picture Experts Group (MPEG). Apparatus according to the present invention filters out high diagonal frequencies in the spatial domain of a video signal. Specifically, two dimensional (2-D) filtering is performed on frames of a video signal to filter out high diagonal spatial frequencies before the video signal is separated into blocks. These blocks may be encoded in fewer bits due to the elimination of image components having high diagonal frequencies.
