Title: In-line detector system for real-time determination of impurity concentration in a flowing gas stream
Inventor: TOM GLENN M
IPC: G01N33/00
Filed: 1991-12-13
Abstract: An in-line detector system (100) for real-time detection of impurity concentration in a flowing gas stream in which purified and unpurified volumes of gas from the flowing gas stream are subjected to concentration sensing, to determine a corrected impurity concentration value for the flowing gas stream. The system in a preferred embodiment employs a manifold (222) in flow communication with a purifier unit (208), a main flow conduit (202) through which the flowing gas stream is passed, and a sensor port (212), with a selectively positionable valve (230) to flow gas through a purifier loop (210, 224) of the manifold to the sensing port (212), and alternately through a bypass loop (226, 228) of the manifold without passage through the purifier unit, for comparative imputiy sensing of gas in the respective loops. The system may utilize hygrometric sensors in the case of water as a critical impurity, or surface acoustical wave (SAW) devices coated with suitable impurity-affinity coatings. The system has particular utility in monitoring low impurity concentration levels (e.g., from about 0.1 ppm to about 100 ppm) in gas streams employed in vapor-phase processes such as chemical vapor deposition in the manufacture of semiconductor devices.

Title: Polyoxypropylene/polyoxyethylene copolymers with improved biological activity
Inventor: EMANUELE R MARTIN
IPC: A61K31/765
Filed: 1992-03-18
Abstract: The present invention comprises novel preparations of polyoxypropylene/polyoxyethylene copolymers which retain the therapeutic activity of the commercial preparations, but are substantially free from the undesirable effects which are inherent in the prior art preparations. The preparation entails first condensing propylene oxide to produce a polyoxypropylene polymer and then condensing ethylene oxide with the polyoxypropylene polymer to produce a polyoxypropylene/polyoxyethylene block copolymer of the general formula:      HO(C2H4O)b(C3H6O)a(C2H4O)b H wherein a and b are integers. Because the preparations of polyoxypropylene/polyoxyethylene copolymers which comprise the present invention are a less polydisperse population of molecules than the prior art polyoxypropylene/polyoxyethylene copolymers, the biological activity of the copolymers is better defined and more predictable. The polydispersity of the copolymer is very low, average less than 1.07.

IPC: H04B1/04
Filed: 1992-04-08
Abstract: Power control circuitry (100) uses two attenuator in the transmit path to achieve wide dynamic range. An intermediate frequency (IF) attenuator (200) is placed before a mixer (212) in the IF section of the transmit path and a radio frequency (RF) attenuator (221) is placed after the mixer (212) in the RF section of the transmit path. Power control circuitry (236) controls setting of the two attenuators in response to a magnitude control signal (102) related to an RF output signal at a desired power level. To conserve battery power of the subscriber unit, only the RF attenuator (221) is adjusted when the desired power level is to be within a given range below the maximum transmission level. For ranges below the given range, the RF attenuator (221) is set for maximum attenuation and the IF attenuator (200) is adjusted.

Patent CA-2114675-A1 (CA)
Inventor: FOGARTY RICHARD
IPC: G01N27/407
Filed: 1994-02-01
Abstract: The investigation of indoor air quality (IAQ) complaints is complex since, unlike industrial settings, there is no obvious source of contaminants. In general, though, the sources of contamination fall into one of three categories - gases/vapours, particulates and microbial material. This patent application relates to the investigation of contamination by gases and vapours.   The most popular, current investigative techniques for addressing gas and vapourcontamination are:   i) to test for carbon dioxide as an estimation of fresh air supply, and ii) to postulate what gas is present and may be causing the problem and test for that gas. Once the presence of the gas is verified, attempts are made to identify and eliminate the source.   This new technique uses a different logic. Rather than postulating the identity of a specific gas, this technique uses a detector sensitive to minute quantities of numerous chemicals to track sources of any chemical so that they may be addressed.            The key points of the technique are:   1) it does not focus on any particular gas or vapour. Anything which is detected by the instrument is tracked to its source and eliminated. In most investigators there is usually no determination of the actual identity of the offending gas;   2) it relies on a meter with both a fast response time and a sensitive detector; 3) the evaluation is usually completed within a matter of hours.

Patent CA-2117871-A1 (CA)
Inventor: KEMPSTER ROBERT W
IPC: G01N27/74
Filed: 1994-10-11
Abstract: A device to detect the presence of particles, principally metallic particles, in fluid lines.  The fluid to be sampled flows through a former on which is wound a coil assembly comprising a sensor coil flanked upstream and downstream by two field coils.  The former is constructed with a double wall and air gap such that pressure fluctuations in the fluid are not transmitted to the coil assembly to adversely affect the positions and readings of the coils.  The field coils are driven by a high frequency signal derived from a crystal oscillator and the upstream and downstream sections are wound in opposite directions such that the magnetic field from each section is cancelled out in the plane of the sense coil.  When a ferromagnetic or conductive particle passes through the winding structure, the coupling in the sense coil is disturbed as the particle first interacts with the field in the upstream section of the field coil and later with the field in the downstream section of the field coil as it passes through the Sensor Coil Assembly (SCA).  A characteristic signature is generated in the sense coil which results from the vector summation of these transient imbalance signals with the steady-state signal from the opposed field coils.  Analysis of the phase of this signature can be used to detect and distinguish between the presence of ferromagnetic and non-ferromagnetic conductive particles.  Since ferromagnetic and non-ferromagnetic conductive particles interact with the field via permeability and eddy current effects respectively, the transient phase signature has a characteristic lag-lead or lead-lag sequence depending on the nature of the particle.

Title: Methods for administering biological agents and microparticle compositions useful in these and other methods
Inventor: CRAFT LIBBEY S
IPC: A61K9/127
Filed: 1994-05-25
Abstract: ABSTRACT     A method for administering biological agents to eggs is disclosed which comprises providing the agents in a particulate carrier and injecting the carrier into the air cells of the eggs.  The egg is preferably maintained in a vertical position with the air cell on top to facilitate migration of the particulate carrier between the inner and outer membranes which define the air cell, to the lower end of the egg.  The particulate carrier releases the biological agent to the surrounding fluid and blood vessels.  In addition, the carrier is embodied in the bird upon hatching from the egg, and therefore is available to continue to release the biological agent to the bird posthatch.   Also disclosed is a composition of polyester microparticles containing bioactive polypeptide agents and methods for preparing the composition and administering bioactive agents.  The composition comprises biocompatible, biodegradable microparticles having a polyester matrix and from about 5% to about 25% by weight of a biologically active, water-soluble polypeptide dispersed throughout the matrix, the polypeptide selected fom the group consisting of growth hormone releasing factor, synthetic analogs of growth hormone releasing factor, and pharmacologically active fragments thereof.  The method for preparing the composition includes dissolving polyester in an organic solvent; suspending a biologically active agent in the polyester solution; emulsifying the suspension into an aqueous medium in which the agent is insoluble and evaporating the solvent from the emulsion to produce microparticles.  The method for administering a bioactive agent to an organism involves suspending the microparticles in a suitable liquid and injecting the organism.
