Title: Purification par voie chromatographique du chlorhydrate de vancomycine a l'aide de la clhp de preparation
Inventor: GRAHEK ROK
IPC: C07K1/16
Filed: 1996-02-06
Abstract: Nouveau procédé de purification du chlorhydrate de vancomycine par la chromatographie liquide à haute performance (CLHP) de préparation (procédé de chromatographie par déplacement), afin d'obtenir un produit ayant une pureté chromatographique essentiellement améliorée. La chromatographie s'effectue sur une phase stationnaire inverse avec une phase mobile constituée d'un acide organique ou minéral ou d'un tampon avec d'éventuels additifs et avec différents agents de déplacement, le pH et la température étant déterminés, tout comme la quantité et la concentration du chlorhydrate de vancomycine. Ce procédé est caractérisé par le rendement excellent et la pureté chromatographique exceptionnelle (95,5 %) du produit obtenu. De plus, ce procédé est irréprochable sur le plan écologique. Le chlorhydrate de vancomycine purifié selon ce procédé convient à toutes les applications car sa teneur en impuretés est inférieure d'un tiers à celle des produits connus jusqu'à présent et disponibles dans le commerce.

Inventor: TURNER JAMES ARTHUR
IPC: D21F9/00
Filed: 1997-08-11
Abstract: A twin wire former has a lower wire extending between an open mesh forming roll and a turning roll. An upper wire joins the lower wire over the forming roll and the upper and lower wires follow a curved generally downwardly extending path or forming zone. The top ply is formed between the upper and the lower wires. A headbox supplies a stream of stock onto the lower wire as the lower wire wraps around the open mesh forming roll. As the lower wire approaches the apex of the forming roll it is joined by the top wire. The upper side of the web is dewatered solely by wire tension and centrifugal forces whichprevent fines and filler materials from being removed in the dewatering process.The turning roll brings the upper side of the web into engagement with a base ply on a base wire.

Patent CA-2240414-A1 (CA)
Title: Isolated electrical power supply
Inventor: CARLSON CURT S
IPC: H02H9/04
Filed: 1996-12-10
Abstract: An isolated power supply for protecting electrical devices from transient voltages and currents is disclosed. Specifically, the filter has a toroid (110) and resistor (102) which are used in conjunction with an isolator transformer (30). The transformer's secondary windings (124) are coupled to the electrical load (12) sought to be isolated. The primary windings (122) of the transformer are tied to an alternating current source (14) with an earth ground lead (18). The primary shield lead (138) of the transformer is tied to the earth ground lead. The secondary shield lead (134) of the transformer is also tied to the earth ground. A toroid inductor and resistor in parallel are coupled between the secondary neutral lead (68) and the secondary ground lead (70) to shunt off current or voltage spikes. The earth ground is part of a chassis which prevents spark jump insuring the isolation of the power source.  The isolator thus provides equal voltage potential between the secondary lead and the primary earth ground at frequencies of less than 1 kHz.

Patent CA-2242184-A1 (CA)
Inventor: NORWOOD JOHN V
IPC: G09F7/18
Filed: 1998-07-03
Abstract: A sign adapted to be quickly and easily attached to and removed from a rope. The sign has a split-T portion defining flexible arms. The arms are bent to allow the rope to slide through transition slots to ultimately enter rope engaging channels. The arms are then released so that the transition slots have a width which restricts passage of the rope, thereby confining the rope to the rope engaging channels. The deflecting portions of the arms are located near the center of the sign to correspond with the natural position of a person's thumbs when holding the sign. The sign allows a new method for attaching a sign to a rope to be used, in which both arms are simultaneously bent from the center of the sign to insert the rope in the rope engaging channels.

Title: Process for sequentially applying sagd to adjacent sections of a petroleum reservoir
Inventor: GOOD WILLIAM KEITH
IPC: E21B43/24
Filed: 1998-10-26
Abstract: Steam assisted gravity drainage ("SAGD") is practised in a first section of a reservoir containing heavy oil. When production becomes uneconomic, steam injection into the first section is terminated. Non-condensible gas is then injected into the section to pressurize it and production of residual oil and steam condensate is continued. Concurrently with pressurization, SAGD is practised in an adjacent reservoir section. As a result, some of the residual oil in the first section is recovered and steam loss from the second section to the first section is minimized.

Title: Method and apparatus for forward link rate scheduling
Inventor: ODENWALDER JOSEPH P
IPC: H04B7/26
Filed: 1998-02-10
Abstract: In a communication system capable of variable rate transmission, scheduling of high speed data transmission improves utilization of the forward link and decreases the transmission delay in data communication. Each remote station (6) is assigned one primary code channel for the duration of the communication with a cell. Secondary code channels of various types and transmission capabilities can be assigned by a channel scheduler (12) for scheduled transmission of data traffic at high rates. Secondary code channels are assigned in accordance with a set of system goals, a list of parameters, and collected information on the status of the communication network. Secondary code channels can be grouped into sets of secondary code channels. Data is partitioned in data frames and transmitted over the primary and secondary code channels which have been assigned to the scheduled user.

Title: Process for monitoring patients with chronic congestive heart failure
Inventor: FELDMAN CHARLES L
IPC: A61N1/362
Filed: 1997-04-22
Abstract: In a process (10) for monitoring patients with chronic congestive heart failure, a high frequency current is passed between electrodes (20) applied to two limbs of a patient. The current, voltage and phase angle between the measured current and voltage are measured (18) to enable the calculation of congestive heart failure (CHF) indicia values. The calculated CHF indicia values are then compared with baseline values established when the patient is in a known, stable condition. Intervention is initiated if the differences between the calculated CHF indicia values and the baseline values are outside of established tolerances. The CHF indicia values may include resistance, reactance, impedance, total body water and extracellular water. Moreover, the indicia values may include a figure of merit indicative of the hydration status of the patient.
