Filed: 2000-05-29
Abstract: A two component chemically thermoset composite resin matrix for use in composite manufacturing processes includes a solvent free polyisocyanate component and a solvent free polyol component. The solvent free polyisocyanate component is either an aromatic polyisocyanate, an aliphatic polyisocyanate or a blend of both. The solvent free polyol component is either a polyether polyol, a polyester polyol or a blend of both. The polyisocyanate component and the polyol component are in relative proportions in accordance with an OH/NCO equivalent ratio of 1:1 to 1:2.

Title: Crash barrier and barrier elements
Inventor: ENGLUND GUNNAR
IPC: E01F15/08
Filed: 1999-02-05
Abstract: The present invention relates to a crash barrier which is adapted to be arranged in the middle of a dual carriageway and which is composed of a plurality of elongate barrier elements (1), preferably made of concrete, which are arranged successively with the short sides of the respective barrier elements neighbouring each other. Neighbouring barrier elements (1, 1') are interconnected by means of articulated connections (5, 6, 5', 6', 8), which prevent lateral displacement of the interconnected short sides relative to each other, but permit force-absorbing deformation of the crash barrier by pivoting of the barrier elements relative to each other in case a vehicle collides with the crash barrier. Each barrier element has at least two projecting connecting elements (5, 6) from each short side, which are connected with corresponding connecting elements (5', 6') of a neighbouring barrier element (1') by means of a rod (8) which is passed through holes (7) in each connecting element. A sleeve (9) cast into the barrier element (1) permits limited displacement of the connecting elements (5, 6) between two end positions.

Title: Method of compensating for erroneous reading in a mass flow meter
Inventor: YOUNG GARY C
IPC: G01F1/66
Filed: 2000-10-05
Abstract: A method of correcting reading of a non-contact solids flow meter measuring solid particulate flow where the solid particulate product enters the flow tube at one end and flows past a sensor and then exits the flow tube. The sensor for the flow meter is very sensitive and not only can sense particulate flow, but can also pick up system machinery motion such as the rotation of a screw conveyor or other moving machinery parts as product flow and provide a system output reading in excess of the actual flow rate. In addition, if the product flow creates dust during the initial calibration process, and the dust is controlled at the actual installation, the system output reading may indicate a flow rate substantially less than the actual flow. The calibration method of this invention uses the original calibration or performance curves to accurately correct the output readings.

Filed: 2000-03-03
Abstract: By clarifying the properties of OmpT protease, a novel use thereof as a protease and a novel method of producing a target polypeptide are provided. More particularly, the present invention relates to a method of controlling cleavage of a polypeptide by OmpT protease which comprises converting a sequence site consisting of two arbitrary consecutive amino acids and/or amino acid(s) in the vicinity of said site in said polypeptide into other amino acids, characterized by (1) setting lysine or arginine as the amino acid at the -1-position concerning said site and setting a specific amino acid as the amino acid at the +1-position; and/or (2) setting specific amino acid(s) as the amino acid(s) at the -4-position and/or the -6-position relative to said site; so that desired parts of said polypeptide are cleaved by OmpT protease and/or undesired parts of said polypeptide are not cleaved by ompT  protease. For example, the present invention provides a method of treating by OmpT protease a fusion protein having an amino acid sequence wherein the amino acid at the +1-position is X (wherein X is an amino acid other than glutamic acid, aspartic acid or proline); and a method of controlling cleavage by converting the amino acids at the -6-position and the -4-position concerning the cleavage site into amino acids other than acidic amino acids.

Title: Function block apparatus for viewing data in a process control system
Inventor: BROWN LARRY K
IPC: G05B19/406
Filed: 1999-03-24
Abstract: The present invention is directed to a method of and a device for monitoring, from a central location, the current operating conditions (such as values of process parameters) in a process control network having distributed control functions. In one embodiment, the method and device of the present invention use scheduled periodic communications to send signals containing, for example, measured values of process parameters developed by field devices to a centralized viewing device.  The viewing device receives the signals and stores at least one value of the process parameters, and maybe more values if necessary to monitor and control the process. To retrieve the stored process parameters for viewing, the viewing device processes messages from humain interface devices requesting the stored values of one or more of the stored parameters and then transmits response messages containing the stored values. The humain interface device may be the same device as the viewing device, or may be a separate device that communicates with the viewing device using either the same or a different communication protocol as that used by the field devices to communicate with the viewing device. Additionally, the request and response messages may be sent between the devices using unscheduled queued communications.
Patent CA-2338826-A1 (CA)
Title: The copy protection of digital audio compact discs
Inventor: EDWARDS ROGER
IPC: G11B20/12
Filed: 2000-05-25
Abstract: Digital audio compact discs (CD-DA) which carry audio can be played and read by CD-ROM drives. Thus the data on the CD-DA may be read into a computer by way of its ROM drive and copied onto another disc. The increasing availability of recorders able to write to CD's poses an enormous threat to the music industry. To copy protect a digital audio compact disc (6), where control data useable by a data reader is encoded on the disc, selected control data is rendered incorrect and/or inaccurate. The incorrect data is either inaccessible to, or not generally read by, an audio player such that a legitimate audio CD which has been copy protected can be played normally on an audio player. However, the incorrect data renders the CD unplayable by a data reader.

IPC: H04W28/18
Filed: 1999-09-21
Abstract: Des systèmes téléphoniques cellulaires sont susceptibles d'avoir à traiter des communications de données à débit élevé pour lesquelles de multiples voies à plein débit sont utilisées. Il est important d'augmenter la disponibilité du système pour ces communications de données à débit élevé et de conserver simultanément la qualité des liaisons radio dans le réseau radiocellulaire. Un premier tri (310) est assuré pour la recherche des voies à plein débit (FR) correspondant à un type de service de communication (300) demandé, situé au-dessous du seuil de coût autorisé par l'opérateur, en fonction des conditions radio. Parmi les voies FR triées, un deuxième tri (320) est assuré pour la recherche des combinaisons de voies à plein débit multiples qui correspondent à un débit de service de communication demandé (300). La communication est ensuite attribuée (340) à la combinaison de voies trouvée, occasionnant le coût le plus faible. Autrement, le système réduit le débit de service demandé (360) de la communication (300) et essaie à nouveau de passer la communication (300) dans une voie de la combinaison de voies plein débit multiples. Si la communication (300) a atteint le débit de service acceptable minimum (350), le système réduit la communication à débit élevé existante (380), et essaie de passer la communication (300) dans une combinaison de voies plein débit multiples. Une fonctionnalité supplémentaire permet au système d'assurer des transferts (334) intra-cellule ou intra-fréquence.
