Patent CA-2246376-A1 (CA)
Inventor: HATLO JAN KARE
IPC: A01C23/02
Filed: 1997-02-14
Abstract: In a method for periodic depositing of liquid manure such as slurry in a soil (80) the slurry is injected in a concentrated jet (9) under pressure, with the result that the slurry forms and fills a groove (6) in the soil, which groove (6) is preferably closed after the injection. A device (1) for use in the method comprises at least one nozzle (5) with a breaker element (10) for periodic interruption of or opening for an injection jet (9) in an outlet direction (P2), the nozzle preferably being provided as an opening from a chamber (3, 29, 35, 38, 52, 72) pressurized with slurry. The breaker element (10) may be rotatably mounted about a rotation axis (22) which is parallel to the nozzle's outlet direction (P2) and is located beside the nozzle (5), with the result that during a rotational movement the breaker element periodically interrupts the injection jet (9).

Title: Block copolymers interpolymerized with in situ polystyrene and process for preparation thereof
Inventor: GRAVES DANIEL F
IPC: C08F287/00
Filed: 1998-09-17
Abstract: A process for interpolymerizing a vinyl aromatic hydrocarbon polymer and a block polymer is disclosed. The process includes the following steps: a) forming a block polymer precursor of at least one polymeric block containing conjugated diene monomer contributed units in the presence of an anionic initiator and in an inert diluent, the block polymer precursor having living ends; (b) thereafter adding to the block polymer precursor a charge of a vinyl aromatic hydrocarbon monomer and an additional charge of an anionic initiator to simultaneously form (1) a block polymer having a terminal block formed from the charge of vinyl aromatic hydrocarbon monomer attached to the block polymer precursor and (2) a poly(vinyl aromatic hydrocarbon) polymer interpolymerized with the block polymer. The practice of this process produces a vinyl aromatic hydrocarbon block terminated block polymer, such as SBS, interpolymerized with a polymer formed from vinyl aromatic hydrocarbon monomer, such as polystyrene. The resultant interpolymer has a high Gardner Impact strength and good processibility.

Title: Ku deficient cells and non-human transgenic animals
Inventor: LIM DAE-SIK
IPC: A01K67/027
Filed: 1997-08-07
Abstract: Ku deficient cells and transgenic animals are described that comprise at least one allele of the XRCC5 gene that has been mutated by targeted disruption.  Fibroblasts derived from XRCC5 mutant embryos and mice were found to prematurely age. These cells displayed decreased growth, slow entry into S  phase, altered colony side distribution that favored small colonies, short life span and morphology characteristic of terminal differentiation. Mutant cells were also hypersensitive to .gamma.-radiation. The tissue culture data was at least partly reproduced in vivo because mutant mice grew slower than control littermates. The XRCC5 mutation, designated xrcc5M1, was a deletion of nucleotides 701-964 that shifted the reading frame. xrcc5M1 is expected to be null because the deleted allele produced no detectable transcript and because lymphocyte development and V(D)J recombination was severely disrupted.

Title: Method and apparatus for objective speech quality measurements of telecommunication equipment
Inventor: HOLLIER MICHAEL PETER
IPC: H04M1/24
Filed: 1993-06-24
Abstract: A telecommunications testing apparatus comprises a signal generator (7) which generates a speech-like synthetic signal, which is supplied to the input of a telecommunication apparatus (1) to be tested. The distorted output of the telecommunications apparatus (1) is supplied to an analysis used (8), which derives, for both the undistorted test signal and the distorted signal from the telecommunications apparatus (1), a measure of the excitation of the human auditory system generated by both signals, taking into account both spectral masking and temporal masking phenomena. The difference between the two excitations is then calculated, and a measure of the loudness of the difference, and the statistical distribution of this loudness over pitch and time, is derived which is found to indicate to a high degree of accuracy the human subjective response to the distortion introduced by the telecommunications system.
