Patent CA-2121889-C (CA)
Title: Production and use of multimeric hemoglobins
Inventor: ANDERSON DAVID C
IPC: C12N15/12
Filed: 1992-11-06
Granted: 2001-08-21
Abstract: The present invention relates to multimeric hemoglobin-like proteins wherein two or more tetramers or pseudotetramers are covalently bonded. Between any pair of covalently linked tetramers, the covalent linkage may take the form of a crosslink between two cysteine residues of different polypeptide chain, or of a peptide linker connecting the "carboxy most" residue of a globin-like domain of one tetramer with the "amino most" residue of a similar domain of a second tetramer. Preferably, the multimeric hemoglobin-like protein-containing composition is at least 50% monodisperse, more preferably, at least 95% monodisperse. Although free hemoglobin purified from natural sources may be polymerized by chemical crosslinking to increase halflife via increased molecular weight, and to reduce oncotic pressure, all such preparations are heterogeneous. Monodispersability can be achieved only by laborious purification. The present invention provides means of exerting strict control over the degree of polymerization of hemoglobin tetramers. The ability to strictly control formation of multimers will greatly facilitate purification and characterization of the final product and will reduce the chance of adverse reaction to minor components. It is also believed that a more mono-disperse composition will have greater consistency of clinical effect.

Title: Method and apparatus for configuring computer programs from available subprograms
Inventor: HURLEY DANIEL F
IPC: G06F9/06
Filed: 1994-07-20
Granted: 1999-12-28
Abstract: A graphic program configuration system is described that allows a user to create complete computer programs. In particular, the present invention improves on the prior art by providing a system and process that permits a subprogram to have an arbitrary number of outlets that may be defined at program configuration time by stimulating the subprogram to create new outlets that facilitate connecting the subprogram to other subprograms. In particular embodiments of the invention the names for the new outlets may either a) be obtained by virtue of the attempted connection of a subprogram to other subprograms or b) be provided direct entry of the outlet name by a user of the program configuration system, e.g., by typing the outlet names on the keyboard. Additionally, in accordance with an aspect of the invention, outlets can be augmented to have one or more constraining parameters that can be used to ensure that only appropriate relationships are established by connections. Such constraining parameters include: a) number of connections allowed, b) types of connections allowed, c) destination object class, and d) destination object operations required. Thus, a non-programmer or a person with only rudimentary programming skills can configure a collection of one or more subprograms into a complete computer program.

Filed: 1993-09-08
Granted: 1999-02-23
Abstract: A method and an apparatus (30) for removing mercury from contaminated soils and industrial wastes are provided. The removed mercury may be recovered. A furnace (8) vaporizes the mercury containing portion and the vapors are condensed. In one embodiment, an initial heating stage volatilizes water vapor and other volatile contaminants, such as hydrocarbons, with substantial vaporization of the mercury-containing portion, subsequently, a second temperature higher than the first is employed to vaporize the mercury containing portion. In one embodiment, a metallic salt reacts with sulfur in the material to form a stable solid sulfur compound to reduce sulfur content in the gaseous effluent. The addition of a metallic salt may also be employed to react with mercury halides to release elemental mecury therefrom. The contaminated material is thereby converted from one which is hazardous due to mercury contamination to one which is non-hazardous. The effluent is treated to reduce environmental hazards in the same. The system (30) is preferably provided on or in a vehicle (11, 12, 13, 14) so as to facilitate treatment of the contaminated materials at the site of the same.

Abstract: A loadbreak switch is provided that utilizes a pivotally mounted movable jaw contact and a main stationary contact that is positioned in the middle of an arc runner. For operation at voltages 15kV and above, the switch utilizes a shunt contact that bridges the arc runner and that is above and coplanar with the main stationary contact. A magnetic field is developed by the current that flows through a coil of wire disposed around the arc runner. This configuration when utilized in an environment of insulating gas, provides efficient extinguishing of arcs upon opening of the contacts. Further, the open jaw contact is easily visible to establish an open gap.

Title: Method and apparatus for measuring the flow rate of a medium flow
Inventor: HUIBERTS ALBERTUS THEODORUS
IPC: G01F1/684
Filed: 1993-10-29
Granted: 2000-01-11
Abstract: A method and apparatus for measuring the flow rate of a medium flowing through a channel, which medium may be a gas or a liquid, comprise the provision inside the channel of a number of measurement sites along which the medium flows continuously at different velocities. The flow of the medium is measured at a number of measurement sites, the flow measurement comprising heating of the medium at the measurement site and measurement of the temperature change at the measurement site as a result of the heating. A rule is established beforehand wherein calibration information is processed for the flow measurement for each measurement site. The calibration information for the predetermined rule comprises, for each measurement site, information about the measurement accuracy over the measurement range of the measurement site. The flow rate to be measured is established on the basis of the measurement result of a measurement site which gives the greatest measurement accuracy according to the predetermined rule. In particular, measurement of the flow at a measurement site comprises heating the medium during a first interval and, during a second interval which follows the first interval, monitoring a temperature reduction at the measurement site. The flow rate is established on the basis of the temperature reduction.  The apparatus comprises no moving components.

Title: Bellows type air spring and method of making same
Inventor: BURKLEY THOMAS EDWARD
IPC: F16F9/05
Filed: 1995-08-29
Granted: 2005-04-12
Abstract: A bellows type air spring having a circular lobed body member with an inner an outer rubberized fabric reinforcing ply and a bead ring at each end. The turn up portion at each end of the fabric layers is wrapped around the bead ring with the turn up portion of the inner ply extending axially inwardly from the bead ring a substantial distance beyond the end of the turn up portion of the outer ply on both ends of the spring to provide longer flex life and prevent premature cracking of the body member in the areas of the end bead rings. The manufacturing method involves the use of an inner fabric ply that is substantially longer in the axial direction than the outer ply instead of using both inner plies of the same axial length.

Title: System and method for generating precise position determinations using gps and pseudolites
Inventor: COHEN CLARK EMERSON
IPC: G01S19/11
Filed: 1994-03-22
Granted: 2000-05-16
Abstract: A GPS system for determining precise position, for example of an aircraft during its final approach to landing.      The GPS system (20) includes a ground based GPS reference system which receives, with a reference receiver, GPS signals (25) and makes carrier phase measurements. The GPS reference system generates and broadcasts one or more pseudolite signals (27) each having a carrier component and a data link signal (30) having data representing the phase measurements made by the GPS reference system. The GPS system includes a GPS mobile system which receives, with a position receiver, the same GPS signals as were received by the reference receiver and the data link and pseudolite signals broadcast by the GPS reference system. In response to the phase measurements made by both the reference receiver and the position receiver during an initialization period, the position receiver resolves the integer wavelength ambiguities associated with the phase measurements. The resolved integer wavelength ambiguities are used by the position receiver after the initialization period to generate precise position determinations for the GPS mobile system.
