Title: Method and apparatus for continuously separating mercury from flowing gases
Inventor: SCHERER VOLKER
IPC: B01D53/64
Filed: 1995-05-30
Abstract: A method and apparatus for the continuous separation of mercury from flowing gases, in particular from exhaust gases from thermal processes, e.g. melting of mercury containing glas shards from fluorescent lamps.  At least one halogen, in particular iodine and/or bromine, is added to the gases when they flow into a reaction vessel.  The halogen reacts with the mercury to form mercury halide, which is separated in the solid state from the gases prior to their outflow from the reaction vessel, for example by deposition on a cooled metal surface or by filtration. Excess halogen is separated by means of adsorption.  A regulating device is optionally provided which readjusts the feed rate of the halogen in such a way that a predetermined small mercury concentration is set in the outflowing gases, e.g. less than 0.2 mg per m3 of gas.
Patent CA-2153590-A1 (CA)
Inventor: HALDENBY GEORGE A
IPC: F17C1/10
Filed: 1994-01-21
Abstract: The present invention provides a method for coating the interior surface of a cylinder (13) with a uniform, relatively thick layer of a polymeric material (37). The method includes the steps of dispers-ing a particulate polymeric material into the interior cavity of a cylinder. Any openings in the cylinder are then closed. The cylinder is then subjected to rotational movement while at the same time subject-ing the cylinder to oscillation in a verti-cal plane. The polymeric material is then heated to a temperature above the melting point of the polymeric material, and main-tained at that temperature for a time suf-ficient to coat the polymeric material onto the interior surface of the cylinder. The rotation and oscillation of the cylinder is then halted and the polymeric material is cooled.

Title: Ignition compositions for inflator gas generators
Inventor: POOLE DONALD R
IPC: C06B33/10
Filed: 1994-10-03
Abstract: Autoigniting compositions containing a hydrazine salt of 3-nitro-1, 2, 4-triazole-5-one for the gas generator of a vehicle occupant restraint system result in rapid autoignition at temperatures from approximately 150 ·C (302 ·F) to 220 ·C (428 ·F) thereby allowing the gas generator to operate at lower temperatures to facilitate use of an aluminium canister. The autoignition compositions of the present invention are relatively insensitive to shock or impact, are safe to manufacture and handle, and are advantageously classified as Class B materials.

Title: Methods of affecting the growth of living tissue in mammals and compounds and compositions therefor
Inventor: BARNATHAN ELLIOT
IPC: A61K31/715
Filed: 1994-03-31
Abstract: Methods and compositions for affecting the growth of cells of living tissue in mammals. The compositions comprise a metabolic inhibitor of a glycolytic pathway of cells and/or an agent which causes an increase in the concentration of intracellular sodium, and a physiologically acceptable carrier. The compositions are administered to the patient either alone or in combination with a growth factor. Depending on the desired route of administration the compositions are formulated to have either a very high water solubility or low water solubility. The highly water soluble compositions may be orally administered, whereas the low water soluble compositions may be applied directly to the location of a wound. The compositions are administered to deliver growth factor to a wound or to absorb growth factor present in the body to prevent overstimulation of the wound response. The compositions are useful as wound healing materials, including wounds associated with abnormally proliferating and/or migrating cells, for example, smooth muscle cells, which are associated with restenosis.

The raw batch is then molded/shaped into a green body and heated to carbonize any carbonizable materials and to decompose and volatilize the organic filler to form a matrix of interconnected pores. The green body is pressureless sintered to densify the matrix. The interconnected pores may then be impregnated with a resin, carbon, metal, TEFLONTM, compound or other material selected for desired tribological characteristics.

Title: Apparatus and method for diagnosing vehicle electrical system
Inventor: KERCHAERT ROBERT B
IPC: G01M17/007
Filed: 1995-12-08
Abstract: An apparatus for diagnosing the presence and location of faults within a vehicle's electrical system includes a signal generator for generating an a.c. test signal; a switching circuit connected to an interface between the system's ECU and the system's components for selectively and sequentially applying the a.c. test signal into each electrical lead therein; and a first detector connected to the system's common ground for detecting the system's response to the applied signals, thereby obtaining a set of transitory characteristics for the vehicle's electrical system.  The apparatus further includes an EPROM within which a set of reference characteristics for the vehicle's electrical system is stored; a comparator means for comparing the detected transitory characteristics with the stored set of reference characteristics; and a diagnostic processor responsive to the comparator means for diagnosing the presence of a fault when the detected transitory characteristics of the vehicle's electrical system deviate significantly from the stored set of reference characteristics therefor.  Upon diagnosing the presence of a fault within the vehicle's electrical system, a d.c. test signal is injected under the control of the diagnostic processor using the switching circuit only into the lead or leads of the interface deemed responsible for the deviant system output.  A second detector likewise connected by the switching means only to those leads deemed responsible for the deviant system output detects the reflection of the d.c. test signal for use by the diagnostic processor in determining the location of any existing fault relative to the interface.

Title: Oscillometric blood pressure monitor which automatically determines when to take blood pressure measurements
Inventor: RAMSEY MAYNARD III
IPC: A61B5/0225
Filed: 1996-01-02
Abstract: An automated sphygmomanometer which automatically determines when a blood pressure determination needs to be made.  During a "guard mode" determination, a cuff on an appendage of the patient is frequently inflated to a check pressure, which is preferably below the patient's mean arterial pressure ("MAP"), and the signature (shape, amplitude, pulse period, etc.) of the measured oscillometric signal is compared to a stored signature of a portion of an oscillometric signal at a corresponding portion of the oscillometric envelope determined during a previous blood pressure determination.  If these signals differ by some predetermined amount, it is determined that the patient's blood pressure has changed significantly and that a new blood pressure determination needs to be conducted immediately.  These guard mode determinations are made in addition to the normal blood pressure determinations made at predetermined intervals typically selected by the user.  In addition, the shape of the oscillometric signal is quantified during guard mode so that it is possible to discriminate oscillations on the diastolic side of a patient's oscillometric envelope from oscillations on the systolic side of the patient's oscillometric envelope, thereby preventing a large shift in the oscillometric envelope from going undetected.

Title: High speed self-adjusting clock recovery circuit with frequency detection
Inventor: BUCHWALD AARON W
IPC: H04L7/027
Filed: 1994-07-21
Abstract: A clock recovery circuit based upon an early-late gate approach is applied to high speed serial communication links using NRZ data. The circuit has no systematic phase offset and therefore requires no external phase adjustment circuits or mechanism.  The circuit is used in high speed integrated receivers for applications including fiber optics, disk-drive read/write electronics, mobile communications and high rate twisted pair data transmission in multimedia systems. Quadrature samples (50) are obtained and held which follow the shape of the NRZ data transition as a function of phase offset. The data signal is passed through the limiter (52) giving rise to a sawtooth shaped phase error signal. A derivative of the error function is taken to provide a frequency error signal to provide for frequency detection and assistance in frequency acquisition of the phase lock loop circuit (54, 58, and 60) generating the recovered clock signal (Clock) from a variably controlled oscillator (60).
