Title: Generation of xenogeneic antibodies
Inventor: KUCHERLAPATI RAJU
IPC: A01K67/027
Filed: 1993-07-23
Granted: 2010-05-04
Abstract: The subject invention provides non-human mammalian hosts characterized by inactivated endogenous Ig loci and functional human Ig loci for response to an immunogen to produce human antibodies or analogs thereof. The hosts are produced by multiple genetic modifications of embryonic cells in conjunction with breeding. Different strategies are employed for recombination of the human loci randomly or a1 analogous host loci. Chimeric and transgenic mammals, particularly mice, are provided, having stably integrated large, xenogeneic DNA segments. The segments are introduced by fusion with yeast spheroplasts comprising yeast artificial chromosomes (YACs) which include the xenogeneic DNA segments and a selective marker such as HPRT, and embryonic stem cells.

Abstract: Full directional pickup coverage is realized by employing a pickup arrangement which provides a plurality of audio polar directivity patterns, i.e., directional beams. These polar directivity patterns are formed in a unique embodiment of the invention by generating a plurality of frequency independent time-delayed versions of a corresponding plurality of spatially sampled signals and by combining each of the plurality of spatially sampled signals with one or more selected ones of the time delayed versions to generate at least a similar plurality of polar directivity patterns. More specifically, the spatially sampled signals are combined with the delayed versions in such a manner that a greater number of polar directivity patterns can be considered than the number of spatially sampled signals. In a specific embodiment, the spatially sampled signals are acoustic (audio) and a plurality of microphones arranged in a predetermined spatial configuration

Abstract: Carrier stock for beverage cans or other cans of a type having a chime at an upper end and having a frusto-conical wall below the chime is formed from a single sheet of resilient polymeric material, such as low density polyethylene, with outer band segments defining can-receiving apertures and including outer band segments and inner band segments, which include a pair of substantially linear edges connected by a relatively small radius at an apex, with webs separating the can-receiving apertures in each longitudinal row, with finger-gripping straps, and with a strut-producing strap.  The finger-gripping straps are arranged in pairs and configured such that each finger-gripping strap of each pair extends generally transversely between two of the inner band segments and is curved inwardly toward the other finger-gripping strap of the same pair when the carrier stock is in a flat, unstressed condition.  The strut-producing strap is intermediate the finger-gripping straps and aligned with the apexes of opposed inner edges and is at least twice as wide as any pair of the finger-gripping straps and as the radius of the apex.  Each finger-gripping strap of each pair has an outer edge, which has an indentation curved inwardly toward the other finger-gripping strap of the same pair and extended transversely in opposite directions from the longitudinal midline when the carrier stock is in a flat, unstressed condition.

Title: A transcoder
Inventor: MORRISON DAVID GEOFFREY
IPC: H04N11/20
Filed: 1994-03-25
Granted: 1999-08-24
Abstract: A transcoder (400) for converting a received data stream encoded according to a first coding scheme to a data stream coded according to a second coding scheme, which schemes specify a first and a second maximum amount of jitter that may be present in the encoded data streams, respectively. The transcoder includes a decoder section (204) and an encoder section (206) and is operated such that the data stream received by the encoder section (206) has a non-zero amount of jitter and the encoder section produces a coded data stream having an amount of jitter which is less than or equal to the second maximum amount of jitter. By operating the transcoder to provide a decoded video data stream to the encoder section (206) which retains a degree of jitter relative to the original video signal, the buffer requirements can be minimised therefore providing reduced buffer delay and hence a transcoder with smaller buffer delay than previously obtainable.

Title: Method for instrument determination of a measured variable which changes with time
Inventor: PATZKE JURGEN
IPC: G01N33/86
Filed: 1997-09-26
Granted: 2008-12-30
Abstract: The present invention relates to a method for instrument determination of measured variable L(t) which changes with time, the intention being to determine the maximum value of L(t) in a region with a linear reaction profile, and the time as well as the duration of the reaction time window being variable with the linear region and depending on the nature of the reaction and the reaction conditions. Specifically, the present invention relates to the determination of protein concentrations with the aid of light scatter, which is produced by specific antibodies, in homogeneous solutions. In particular, the invention relates to reactions which take place slowly and have a largely linear profile over a relatively long time, the rate of formation of antigen-antibody complexes in the linear section of the reaction (V MaxLin) being determined as the measured variable.
