Title: Automated system for providing liquidity to securities markets
Inventor: LUPIEN WILLIAM A
IPC: G06Q40/04
Filed: 1990-05-14
Abstract: Abstract of the Disclosure An automated system for managing one or more large investor portfolios containing both cash and numerous, diversified securities in a real time environment provides added liquidity to the securities markets while maintaining predetermined portfolio objectives for each portfolio.  The disclosed system uses data processing equipment to place buy and sell orders on securities markets and with automated brokers to execute trades directly between users of the system and external markets.  Holders of such large, diversified portfolios have usually been long-term investors.          The system allows active market participation by such investors whereby they provide added liquidity and depth to the securities markets while overcoming problems caused by trader identification and the inability to enter, change or execute orders in a real time environment.  The system monitors and analyses a variety of factors which effect trading decisions in a vast number of securities. Such factors include other security trades, price and size quotations and financial ratios for particular securities. This information is further analyzed in relationship to each investor portfolio using the system to determine what transactions might benefit the portfolio by seeking to provide an incremental return while accommodating the basic portfolio objectives. These objectives may be changed at the election of the investor at any time. Orders representing such transactions are entered by the system and executed in real time either internally between system users or externally with computerized brokers and/or stock exchanges and markets.

Title: Method for determining dynamic flow characteristics of multiphase flows
Inventor: HUNT ANDREW
IPC: E21B47/10
Filed: 1990-05-23
Abstract: METHOD FOR DETERMINING DYNAMIC FLOW CHARACTERISTICS                OF MULTIPHASE FLOWS ABSTRACT      The present invention relates to a method for determining at least one dynamic flow characteristic of a multiphase flow circulating in a pipe, said flow being composed of at least a lighter dispersed-phase and a heavier continuous-phase.  A tracer is discharged (or activated) into the flow at a chosen first location in the pipe by mixing (or activating) at least a portion of the tracer with the continuous-phase therein.  The tracer concentration at at least a chosen second location in the pipe is measured with a detector as a function of time t, so as to obtain at least one signal S(t).  Then a relationship is fitted to the signal S(t) so as to derive the values of the velocity U of the continuous phase and/or of a dispersion coefficient k.  The slip velocity vs of the dispersed phase relative to the velocity of the continuous phase is also advantageously determined.      From the values of velocities U and vs and from the volume fraction y1 of the continuous phase in the pipe (obtained by an ancillary measurement), the volumetric flow rates of the continuous and dispersed phases are determined.

Title: Method and apparatus for heterogeneous chemiluminescence assay
Inventor: KHALIL OMAR S
IPC: G01N33/576
Filed: 1990-07-19
Abstract: Apparatus and method for performing a chemiluminescence assay involving the immobilization of a chemiluminescent reaction complex to a solid, porous element. The solid, porous element is preferably treated to provide an immobilizing interaction with the chemiluminescent reaction complex wherein the chemiluminescent reaction complex is thereby immobilized to the solid, porous element. The activating and reading of the chemiluminescent reaction are separately performed by evenly distributing a concentrated chemiluminescent activating solution to form a puddle on the surface of the porous element to which the chemiluminescent reaction complex is immobilized.

Title: Method and apparatus for processing calls entered in elevator cars
Inventor: AIME MICHEL
IPC: B66B1/20
Filed: 1990-08-30
Abstract: In an elevator system with the immediate allocation of the floor calls, car calls are processed according to an algorithm implemented in a process computer. A preliminary processing of the car calls occurs upon entry of each of the car calls and a final processing occurs before the car call destination floor. A car call with a destination floor which coincides with the destination floor of an allocated call is allocated immediately during the preliminary processing. If there is no coincidence, the car call is shortened by one floor and registered. A car call registered during the preliminary processing is allocated with its original trip length during the final processing if there is coincidence with a destination floor of an allocated call. If no coincidence exists, the car call is allocated with a new destination floor which depends upon the allocated calls before and/or after the original car call destination floor.

Patent CA-2033240-A1 (CA)
Inventor: VANDERVAART GERRY
IPC: F25B30/00
Filed: 1990-12-27
Abstract: A  condensing furnace which includes an outdoor coil of  the type having aluminum fins pressed to copper tubes through which a refrigerant is conducted.   Heat is generated,  preferably from a flame,  and  the relatively intense  temperature  (approximately 2200°F.) is  de-intensified before reaching the aluminum fins  by generally sinusoidal de-intensifier tubes positioned between  the flames and the fins of the coil.   Since the de-intensifier tubes reduce  the temperature of the flue of gases virtually  instantly to approximately 50°F.,  condensation forms not only upon the de-intensifier  tubes  but also upon the aluminum fins of  the  coil which prevents acidic deterioration and corrosion thereof,  while at the same time maintaining extremely hight Btu abosorption.

Patent CA-2038613-A1 (CA)
Inventor: NAPPHOLZ TIBOR A
IPC: A61N1/362
Filed: 1991-03-19
Abstract: Abstract A rate-responsive dual-chamber pacemaker and pacing method for supporting the heart with electrical stimulation at a pacing rate driven by the heart's sinus node or, altenatively,by a sensor adapted to determine the patient's metabolic demand (ametabolic demand indicator). The pacemaker automatically selects between the indicated rates to determine the best pacing rate for appropriately satisfying metabolic demand at all times. The natural rate, driven by the sinus node, takes precedence over the metabolic indicator rate provided the natural rate meets a standard determined by the metabolic demand indicator rate. The pacemaker upper rate response mechanism allows atrioventricular synchrony at natural sinus rates ranging from low rates to high excercise rates, even up to the programmed maximum rate, but maintains ventricular rate stability during pathological atrial tachycardias by reverting to pacing in a rate-responsive VVI mode.

Title: Purification of hydrogen peroxide
Inventor: FEASEY NEIL DAVID
IPC: C01B15/013
Filed: 1990-04-06
Abstract: ABSTRACT OF THE DISCLOSURE     The electronics industry demands that hydrogen peroxide for use therein be purified to very low levels of impurities, currently at the level of a few ppb for some impurities, or even lower.  However, existing methods are either inherently unsafe because they bring concentrated hydrogen peroxide into contact with a concentrate of transition metal decomposition agents for peroxide and a purification resin which acts as a source of carbon, or are unable to attain the desired impurity level.  The instant purification process first makes a concentrated suspension of stannic oxide particles in an aqueous medium, which can include aqueous hydrogen peroxide, by subjecting the mixture to high shear mixing, introducing an effective amount of the dispersion into the peroxide solution and filtering the mixture so as to remove the stannic oxide particles that now are loaded with ionic impurities, and particularly with transition metal ions.  Purification to very low impurity levels can accordingly be made with improved safety.
