Patent CA-2035381-A1 (CA)
Inventor: LITTLE MELVYN
IPC: C12N15/70
Filed: 1991-01-31
Abstract: The invention relates to the preparation and use of gene banks of human antibodies (Ab). Starting from a mixture of human B-lymphocytes, their mRNA is translated into the cDNA using oligo-dT primers. Subsequently, an amplification of the Ab-specific cDNA by means of polymerase chain reaction (PCR) takes place using suitable oligonucleotide primer sequences. Expression of this amplified Ab-specific cDNA in a bacterial expression vector, e.g. the vector pFMT described below, in E. coli thus makes available a human-antibody library with a comprehensive repertoire for screening selected antigens in vitro.
Patent CA-2036990-A1 (CA)
Inventor: GRIFFIOEN WILLEM
IPC: G02B6/44
Filed: 1991-02-25
Abstract: The invention comprises an improved method for installing a cable (4) in a tubular cable conduit (6) with the aid of the drag forces of a flowing medium and a pulling plug which can be used in this method. Coupled to the foremost end (8) of the cable in the conduit is a partially leaky pulling plug (10) which is provided with a flow opening (12)  for the flowing medium. Said flow opening (12) is so dimensioned that, on the one hand, no harm is done to the drag forces of the flowing medium along the cable  (4)  but,  on the other hand,  a small pressure difference is maintained across the pulling plug, with the result that the pulling plug (10) energised in this way exerts additional tensile forces on the foremost end (8) of the cable (4) which compensate at least at that point for compressive forces arising as a consequence of intrinsic curvatures. Said flow opening is preferably such that during the installation of a cable the flow velocity in the flow opening (12) is essentially equal to that of sound in the flowing medium (shock wave condition). The flow opening (12) can be chosen as constant, but may also be regulated in a pressure-dependent manner to maintain the said shock wave condition better. Three embodiments of such a partially leaky pulling plug (10) are described, namely one having a constant flow opening, one in which the size of the flow opening varies with an essentially constant pressure difference across the pulling plug and one in which the size of the flow opening varies with the pressure at the position of the pulling plug. The pulling plug preferably has a circumferential suction seal with the inside wall (11) of the conduit (6). Advantages are reduction of the risk of upsetting and buckling, generally greater installation lengths in one stroke, and a lower compressor power.
