Title: Method of selecting propagation delays retained for receiving messages transmitted by spread spectrum radio communication
Inventor: WILK HEINZ
IPC: H04B1/707
Filed: 1996-07-19
Abstract: The signal received in a CDMA system is sampled at a rate greater than the chip rate of the spreading sequences. In order to assign the propagation delays to the arms of a rake receiver, consecutive delays are tested within a time window by evaluating, for each delay tested, an energy of the correlation between the signal received and a reference spreading sequence to which said tested delay is applied. A selection threshold is determined from the largest of the energies evaluated. A first list is compiled containing delays from the window for which the histogram of the evaluated energies exhibits a local maximum greater than the selection threshold, and a second list is compiled containing delays neighbouring the delays of the first list. The delays assigned to the arms of the rake receiver are selected initially from the first list and then, if this is insufficient, from the second list.

Inventor: JOHNSTON VICTOR JAMES
IPC: C07C19/045
Filed: 1996-11-14
Abstract: An improved process is disclosed for manufacturing chlorinated hydrocarbon by way of oxychlorination which yields reduced levels of environmental toxins such as, chlorobenzenes, polychlorinated biphenyls, polychlorinated dibenzodioxins and polychlorinated dibenzofurans.  The process involves fixed bed or fluid bed catalyzed oxychlorination of a hydrocarbon reactant containing from 1 to 3 carbon atoms.  The oxychlorination process consists of contacting the hydrocarbon reactant with oxygen or oxygenated gas and at least a portion of externally obtained hydrogen chloride in the presence of the oxychlorination catalyst in a heated reaction zone operated at from 150~C to 600~C and recovering chlorinated hydrocarbon from the effluents of the reaction zone.  The improvement consists of the use of at least a portion of the hydrogen chloride from an external source other than from recovery of hydrogen chloride from the thermal pyrolysis of the product from the operated oxychlorination process, wherein the external hydrogen chloride, containing aromatic hydrocarbons, is pretreated before use in the operated oxychlorination process by a means for removal of the aromatic hydrocarbons.

Patent CA-2193362-A1 (CA)
Inventor: CUNDELL DIANA R
IPC: A61K31/00
Filed: 1995-06-19
Abstract: La présente invention se rapporte à des compositions et des procédés permettant de prévenir l'infection par pneumocoques. L'invention se rapporte plus particulièrement à l'identification du site de réception majeur de Streptococcus pneumoniae sur des cellules humaines activées, ainsi qu'à des compositions et procédés diagnostiques et thérapeutiques fondés sur cette identification. L'invention porte notamment sur la découverte que le récepteur du facteur d'activation plaquettaire (PAF) est un ligand adhésif entraînant l'adhérence des pneumocoques aux cellules endothéliales vasculaires et épithéliales pulmonaires activées (en d'autres termes des cellules hôtes). En conséquence, un procédé de prévention ou de traitement d'une infection par Streptococcus pneumoniae, selon la présente invention, consiste à administrer un antagoniste du récepteur du facteur d'activation plaquettaire. Il a été en outre reconnu que l'adhérence à des cellules activées implique également un ligand glucidique que l'on trouve sur de telles cellules activées. Ainsi, un procédé d'inhibition de l'adhérence des pneumocoques peut comprendre l'administration d'une certaine quantité d'un glucide contenant une unité N-acétyl-D-glucosamine. Il a été démontré que les cellules épithéliales pulmonaires et endothéliales vasculaires au repos contiennent deux classes de récepteurs comprenant différentes unités glucidiques. Ainsi, un procédé selon l'invention consiste à administrer une certaine quantité d'un second glucide choisi entre un glucide contenant une unité disaccharide N-acétyl-D-galactosamine .beta.1-4Gal, un glucide contenant une unité disaccharide N-acétyl-D-galactosamine .beta.1-3Gal, et un mélange de ceux-ci. L'invention concerne également des compositions pharmaceutiques comprenant de tels agents inhibant la liaison des pneumocoques aux cellules humaines. Dans un exemple spécifique, il est démontré que des antagonistes du récepteur du facteur d'activation plaquettaire et des disaccharides inhibent in vitro la liaison des pneumocoques aux cellules épithéliales pulmonaires et aux cellules endothéliales vasculaires activées, ainsi qu'aux cellules transfectées avec le récepteur du facteur d'activation plaquettaire.

Patent CA-2213240-A1 (CA)
Title: Probes for nucleic acid analysis and method using these probes
Inventor: EBATA KATSUYOSHI
IPC: C12Q1/68
Filed: 1996-02-13
Abstract: A probe for detecting nonradioactive nucleic acids by the hybridization technique, and a highly sensitive and highly selective method for the detection. The probe comprises a set of two or more oligonucleotide probes that can hybridize perfectly complementarily with the specific portion of the sequence of the consecutive bases of the target nucleic acid, each oligonucleotide probe being labeled at the 5' or 3' end thereof with a chromophoric group having a suitable spatial arrangement so that adjacent chromophoric groups can yield an excimer or the like when each probe hybridizes with the target nucleic acid. More specifically, although the probe of the invention comprises a set of two or more labeled probes and the labeling groups to be detected are present each on a different probe, the labeling groups take such a spatial arrangement that the two chromophoric groups present on the two probes which have come to exist adjacent to each other only after the hybridization with the target nucleic acid induce unique phenomena such as excimer fluorescence, thereby enabling the target nucleic acid to be detected with a high recognizability. Thus the probe of the invention enables the erroneous recognition which has been problematic heretofore to be reduced remarkably and the types of utilizable labeling groups to be varied widely. Further it is possible to improve the detection sensitivity remarkably because it is possible to reduce the background noise remarkably. In addition, it is possible to discriminate a number of (single-base variation) nucleic acids that are different from one another in only one base present at a specific position to be detected, which has been difficult heretofore.

Title: Improved locking mechanism for blade of coping saw
Inventor: CHEN RUEY-ZON
IPC: B23D51/14
Filed: 1997-09-24
Abstract: The present invention relates to an improved locking mechanism for blade of coping saw. The free ends of the upper and lower swinging arms of the coping saw is removably disposed with an upper and lower fixing blocks respectively for mounting and bridging a blade therebetween. The blade of general type can be readily bridged and supported between the slits of the upper and lower fixing blocks in usual manner: In assembling, the blade can be suitably disposed between the slit of the upper fixing block and the slit of the lower fixing block. Then a locking screw is suitably passed through the traverse hole of the slit and engaged into the threaded hole. As a result, the upper end of the blade is fixedly attached to the upper fixing block. Similarly, another locking screw is applied and which is passed through the traverse hole of the slit and is finally engaged into the threaded hole. As a result, the lower end of the blade is fixedly attached to the lower fixing block. In case a variant of the blade which has a cross portion at both ends is used, it can be also attached to the upper and lower fixing blocks. In mounting, the upper end of the blade is disposed within the slit such that the cross end is firmly seated onto the upper concave portion. Then a locking screw is applied and which passes through the through hole of the upper block and finally locked into the threaded hole. As a result, the upper end of the variant blade can be suitably supported and locked. Similarly, the lower end of the variant blade is also attached to the lower fixing block in the same manner as the upper end. By this arrangement, the variant blade is fixedly bridged between the upper and lower fixing blocks. By this arrangement, since the variant blade can be fixedly and firmly supported between the upper and lower fixing blocks, the oscillated cutting movement of the variant blade can be more efficiently and smoothly performed without any possibility of removing therefrom. As a result, the existing blades can be suitably disposed and supported between the free ends of the upper and lower ends of the upper and lower swinging arms for cutting movement.
