Title: Glucagon antagonists and methods for detecting glucagon antagonists
Inventor: SMITH ROBERT A
IPC: G01N33/53
Filed: 1993-08-27
Abstract: Methods for detecting glucagon antagonists through the use of recombi-nant DNA techniques are provided. Briefly, subsequent to the expression of glucagon analogs within suitable host cells, the analogs are exposed to a glu-cagon receptor coupled to a response pathway in the presence of native glu-cagon. A reduction in the stimulation of the response pathway resulting from the binding of the glucagon analog to the glucagon receptor relative to the stimula-tion of the response pathway by native glucagon alone indicates the presence of a glucagon antagonist. Glucagon anta-gonists identified and isolated through the methods are also provided.

Title: Method and apparatus of providing time sensitive message over a variable delay channel
Inventor: GROB MATTHEW S
IPC: H04B7/26
Filed: 1994-11-14
Abstract: An apparatus and method of providing communications between standard unmodified terminal equipment over a telephone link that includes a digital wireless link. The digital wireless link introduces substantial time variable delay. In order to pass time sensitive messages over the link, time sensitive messages are recognized and translated into time insensitive messages for transmission over the wireless link. The time insensitive messages indicate the information contained in the time sensitive messages and in the timing of the time sensitive messages. At the receiving end, the time insensitive messages are recognized and the time sensitive messages reconstructed with the appropriate timing.

Title: Method of assessing cardiovascular function
Inventor: PEREL AZRIEL
IPC: A61B5/02
Filed: 1995-07-18
Abstract: Disclosed is a method of analyzing changes in continuously measured hemodynamic parameters in response to a set of predetermined changes in airway pressure or tidal volume.      The method is generally called "respiratory systolic variation test" (RSVT). The analysis of the change in the hemodynamic parameter in response to such airway pressure maneuver serves as a non-invasive or minimally invasive method of assessing the cardiovascular status, particularly the volume responsiveness of the patient.
Patent CA-2155682-A1 (CA)
Inventor: B TH LARS B
IPC: G01S13/36
Filed: 1994-02-03
Abstract: A measuring technique and method are provided to simultaneously determine the positions of the surfaces of slag and metal bath in metallurgical processes. In the metallurgical process industry, e.g. in converter processes, it is important to measure the thickness of the layer of slag on top of the metal bath as well as determine the actual volume of metal in order to determine the weight of the charge. A large number of various methods have been tried, but no method is known to result in fast and accurate measurements of both surfaces from a distance and without mechanical means. The herein presented invention describe a method whereby radio waves are transmitted over a frequency band perpendicular towards the surfaces and how a receiver is used to compare the phase of the reflected waves relative the transmitted wave. The phase-change is measured for a number of frequency channels and a transform is then used to transform from the frequency space to the time delay space which gives the positions. The method is suitable for measuring overlapping surfaces at large distances from the reference level and which arc separated by large distances.  The estimated errors of the method are as low as 2 mm. If an interferometer is used as antenna then the data will also be sampled in the aperture plane and the three dimensional structure of the surfaces can be reconstructed.

Title: Apparatus and method for automatically achieving and maintaining congruent control in an industrial boiler
Inventor: GUNTHER JOHN C
IPC: G05D21/02
Filed: 1995-08-24
Abstract: A control system for automatically achieving and maintaining a desired sodium/phosphate ratio and phosphate concentration of the boiler water in an industrial boiler for minimizing corrosion. The system uses an adaptive controller that models the boiler which enables the system to predict boiler pH and phosphate concentrations at any future time given the feed rates, feed concentrations of high and low sodium/phosphate stocks, blowdown rate, mass of the boiler water, initial boiler phosphate concentration and initial pH. Once these future concentrations are determined, the controller then determines which feed rates will return the current boiler water state to, and then maintain the boiler water at, the desired sodium/phosphate congruency ratio in the least amount of time. Where the controller determines that it is not possible to move the current boiler water state to the desired congruency setpoint, the controller determines a feed rate program that will move the current boiler water state to the attainable steady state point closest to the desired setpoint. An alternative embodiment fixes the phosphate concentration by ratioing the phosphate feed with the blowdown rate while continuously monitoring blowdown pH. This arrangement allows for the control of sodium by switching between the high and low ratio sodium/phosphate stocks based on the measured pH with respect to the pH setpoint.

IPC: C08F4/6592
Filed: 1994-08-15
Abstract: The invention concerns a certain class of polymers, their production into films and applications for their use.  These polymers have unique properties which make them particularly well suited for use in polymeric films.  These films are very useful in applications requiring heat sealability, particularly those applications containing  an ionomer film. It has been discovered that polymers derived from metallocene catalyst systems surprisingly heat seal extremely well, as compared to polymer produced by conventional  Ziegler-Natta catalysts, to a class of polymers known as ionomers.
