Title: Process for extracting and rebuffering and/or concentrating dissolved macro-molecules of a macromolecular mixture
Inventor: BARTHOLMES PETER
IPC: G01N30/96
Filed: 1993-10-13
Abstract: The invention pertains to a process for extracting and buffering and/or concentrating dissolved macromolecules of a mac-romolecular mixture using a liquid chromatography apparatus, wherein buffer solutions that promote the separation process are added to the macromolecular mixture to be separated prior to its entering into the liquid chromatography apparatus or during the separation process in the liquid chromatography apparatus, said buffer solutions then being entirely or partially withdrawn and/ or exchanged after the separation for purposes of concentrating or purifying the kind of molecules extracted. To be able to carry out such a process of buffering and/or concentrating more quickly and continuously with less outlay for equipment, the invention proposes that the buffer solution be withdrawn and/or exchanged by means of countercurent dialysis, which is carried out con-tinuously with the eluate of the liquid chromatography apparatus. The countercurrent dialysis proposed as per the invention makes it possible to supply the eluate with specific low-molecular substrates for the enzymatic detection.

Patent CA-2148150-A1 (CA)
Inventor: DRAGOSET WILLIAM H JR
IPC: G01V1/36
Filed: 1995-04-28
Abstract: A method for adaptively creating a filter for removing coherent environmental noise from a multitrace digitized seismic recording requires the presence, on the recording, of a limited sample of pure noise that is uncontaminated by desired signal.  The pure noise sample is used to discover the location of the noise source and from that discovery, to extrapolate and reconstruct the characteristics of the noise envelope as it would appear on the seismic recording. The reconstructed noise envelope is used as a noise reference for input to a conventional iterative adaptive noise cancellation filter loop.  For stability, the loop gain is minimized by temporally and spatially averaging the filter coefficients for each sample interval.

Title: A system and method for tracking a feature on an object using a redundant axis
Inventor: HUISSOON JAN PAUL
IPC: B25J9/18
Filed: 1994-01-11
Abstract: A system and method for seam tracking in real time without path preprogamming uses as least two degrees of freedom and at least one degree of freedom created by a redundant axis.     A robot can be used to weld or apply adhesive or sealant to a workpiece that is mounted on a positioner that it is movable relative to a base of the robot as a movable end of the robot tracks a seam on the workpiece. A sensor expresses a seam trajectory in workpiece coordinates and queues the coordinates in a computer processor so that the coordinates can be extracted from the processor to cause the movable end of the robot to track the seam. The workpiece can remain stationary and the robot base can be moved or the base can remain stationary and the workpiece can be moved or both the workpiece and the robot base can be moved.     Any reasonable number of redundant axes can be utilized so long as there is one control parameter independently defined for each degree of freedom greater than six. Previous seam tracking systems do not have more than one degree of freedom with one of the degrees of freedom being created by redundant axes and previous systems do not automatically move the robot base relative to the workpiece.

Title: Two-step electrochemical process for coating magnesium
Inventor: LEMIEUX BRIAN E
IPC: C25D11/30
Filed: 1993-02-09
Abstract: A two-step process for the coating of magnesium and its alloys is disclosed.  The first step comprises immersing the magnesium workpiece in a first electrochemical solution comprising about 3 to 10 wt-% of a hydroxide and about 5 to 30 wt-% of a fluoride having a pH of at least about 12. By controlling a current density to about 10 to 200 mA/cm2, an increasing voltage differential is established between an anode comprising the pretreated article and a cathode also in contact with the electrolytic solution. Next, the article is immersed in an aqueous electrolytic solution having a pH of at least about 11 and which solution is prepared from components comprising a water soluble hydroxyde, a fluoride source and a water soluble silicate in amounts to result in an addition of about 2 to 15 g of a hydroxide per liter of solution, about 2 to 14 g of a fluoride per liter of solution and about S to 40 g of a silicate per liter of solution. Again, by controlling the current density to about 5 to 100 mA/cm2, an increasing voltage differential of at least about 150 volts is established between an anode comprising the pretreated article and a cathode also in contact with the electrolytic solution. This process results in a superior coating which has increased abrasion and corrosion resistance.

Abstract: A reverse address resolution protocol for use in a communication network which allows resolution logic to provide a higher level protocol information (such as an IP address) to a source of a request (127) for such information (122), independent of the physical network address of such source. The protocol is used in a processor having a plurality of parts, at least one of such ports connected by a point-to-point channel to a remote network device. Reverse address resolution protocol is responsive (129) to a resolution request from the remote network device across the point-to-point channel to supply the higher level protocol information based upon the port through which the resolution request is received (125), rather than the physical network address of the requesting device. Thus, a remote device may be coupled to a network, and connected to a central management site across a point-to-point communication link, in a "plug and play" mode. The person connecting the device to the remote network does not need to determine the physical network address of the device or configure the device with a higher level address protocol.

Title: Dual loop pid configuration
Inventor: DESANTIS ROMANO M
IPC: G05B13/04
Filed: 1995-08-25
Abstract: The    proportional-integral-derivative-controller  produces  a  process  control  signal  in response to a process variable signal and a setpoint signal.   The process variable signal is subtracted from the setpoint signal  to produce a difference signal, and a signal representative of the derivative of the process variable is produced.  In an inner loop the setpoint signal, the difference signal and the derivative  signal  are  amplified  by  respective adjustable gains.    In an outer loop the process variable  signal  and  the  derivative  signal  are amplified by  respective  adjustable  gains  and  the difference signal is integrated.   The amplified and integrated signals are combined and applied to another adjustable  gain  to  produce  an  outer-loop  output signal.    The  amplified  setpoint,  difference  and derivative signals, and the outer-loop output signal are finally combined to produce the process control signal.   The gains of the inner loop affect the input/output characteristics of the controller and the gains  of  the  outer  loop  the  sensitivity  of  the controller to perturbations.  Also, adjustment of the sensitivity through the gains of the outer loop does not change the input/output characteristics of the controller that have been previously adjusted by means of the gains of the inner loop after having set the gains of the outer loop equal to zero.
