Title: Treatment of bleach plant filtrates
Inventor: HENRICSON KAJ
IPC: D21C9/06
Filed: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE      Filtrates from bleach plants for cellulosic (paper) pulp non-chlorine bleaching sequences are treated to minimize the consumption of ozone in ozone bleaching stages.  Organic material in the filtrate used in a washer just prior to an ozone stage is oxidized to make the organic material less attractive to the ozone.  It may be oxidized by indirectly heating the filtrate, and then reacting it with oxygen gas in a reactor.  Metallic ions are also removed from the system by applying an electrical potential either to the filtrate, an entire washer prior to the ozone stage, or to the pulp line prior to the ozone stage.  Alternately, the filtrate is treated with a fiber filter, and then passes through a magnesium filter, which has magnesium chips with a maximum dimension of about 3 mm or less.  The magnesium removes heavy metal ions, and if any of the magnesium dissolves in the filtrate it provides a beneficial affect on the pulp.  The pH of the filtrate is typically maintained in the 2-6 range to facilitate dissolution of transition metals while the magnesium stays out of solution.  Two filters may be provided in parallel so that if one becomes contaminated the other may be quickly put into service, and any explosive gases from the magnesium filter are vented.

Abstract: A retention bolster for a percutaneous catheter is disclosed having a convexly curved exterior surface which contacts the epidermal surface of a patient.  The retention bolster slides over a catheter until contacting the skin of the patient at the catheter exit site.  When secured in place, the retention bolster rocks along contacting portions between its convexly curved surface and the epidermal surface of the patient in response to movement of the catheter about the exit site, thereby alleviating the added pressure that would otherwise be applied by this movement.  Upon the release of lateral pressure against the catheter device, the bolster returns to its original upright position.  In a second disclosed embodiment, a flange is provided which extends from the main body of the bolster which defines a bore that is also sized for slidably receiving and supporting the catheter, and which provides for angled attachment of the catheter relative to its exit site.

Title: Chemical Ionization Mass Spectrometry Method Using Notch Filter
Inventor: KELLEY PAUL E
IPC: G01N27/62
Filed: 1992-02-11
Abstract: A mass spectrometry method in which notch-filtered noise is applied to an ion trap to resonate all ions except selected reagent ions out of the region (16) of the trapping field. Preferably, the trapping field is a quadrupole trapping field defined by a ring electrode (11) and a pair of end electrodes (12, 13) positioned symmetrically along a z-axis, and the filtered noise is applied to the ring electrode (11) [rather than to the end electrodes (12, 13)] to eject unwanted ions in radial directions [toward the ring electrode (11)] rather than toward a detector (24) mounted along the z-axis.  Application of the filtered noise to the trap in this manner can significantly increase the operating lifetime of such an ion detector.

Title: System and method for removing a volatile component from a matrix
Inventor: MCCABE MARK M
IPC: C02F11/13
Filed: 1992-04-06
Abstract: A system and method is disclosed for removing a volatile component from volatile component-containing matrix. A volatile component-containing matrix, such as a sludge contaminated with volatile organic material or volatile inorganic material, is directed into a housing. The matrix is then directed through the housing by a screw conveyor. A heat transfer medium is conducted through a conduit within the screw conveyor to heat the screw conveyor to a temperature sufficient to volatilize at least a portion of the volatile component. The heat transfer medium can be a molten eutectic salt solution. The volatilized component is transported by a hot gas discharged over the matrix along at least a substantial portion of the length the housing from a gas inlet tube which is disposed above the matrix within the housing and is substantially parallel to the screw conveyor. The hot gas transports the volatilized component into a gas outlet tube which is also disposed above the matrix within the housing and is substantially parallel to the gas inlet tube. The volatilized component is then directed through the gas outlet tube and out of the housing, thereby removing the volatile component from the matrix. The matrix is then discharged from the housing.

Abstract: A clock phase signal of each time slot of a TDM signal is stored into a corresponding memory location and a clock phase signal of a subsequent time slot is read from a memory location corresponding to the subsequent time slot for recovering clock pulses. A decoder is synchronized with the clock pulses for decoding an encoded digital signal of each time slot to produce a decoded signal. The error rate of the decoded signal of each time slot is decoded and compared with a prescribed value. When the detected error rate is determined to be higher than the prescribed value, the write operation of the memory is disabled to prevent the clock phase signal stored in a memory location corresponding to the decoded signal from being overwritten with a subsequent clock phase signal.

Title: Improving muscle tone
Inventor: KALLOK MICHAEL J
IPC: A61N1/36
Filed: 1992-03-24
Abstract: An apparatus for and a method of improving the muscle tone of a patient using chronic subthreshold electrical stimulation. For patients suffering from obstructive sleep apnea, for example, the muscles of the upper airway are stimulated to mitigate or prevent the adverse medical condition, caused, in part, by excessively flaccid muscle tissue around and in the airway. A stimulation generator (160) supplies pulses to the muscle to be treated through insulated leads (66-72), which are coupled to electrodes directly in contact with the appropriate neuromuscular tissue. The output of the stimulation generator is adjusted to an amplitude of sufficiently low level as to prevent fused tetanic contraction of the stimulated muscle. The adjustment may be made manually or automatically using electrodes to sense the tension of the stimulated muscle. In the automatic mode, the sensing system insures the stimulation level is decreased below the threshold of muscle tetanus.   Stimulation may be accomplished at a particular site or may be multiplexed to a number of sites. Chronic stimulation will enhance muscle tone to an individual degree and then will simply maintain the desired status.

Title: Rotor movement sensing system
Inventor: FLUECKIGER DANIEL
IPC: G01P13/00
Filed: 1994-02-02
Abstract: ABSTRACT         A rotor movement sensing system is provided for use in a postage meter to permit detection of the printing of postage even in the event that power is lost during the printing cycle.  A sensor is provided to sense the magnet on a disk when the rotor is substantially past its home position.  This sensor is positioned far enough past the home position that the above-mentioned ratchet will have ensured that the rotor must continue forward to completion of a print cycle.  The second sensor a so-called magnetic memory element ("MME") sensor.  The MME sensor has a magnetic memory element with substantial magnetic hysteresis.  When the disk magnet passes near the memory element, the memory element is magnetized.  A Hall-effect sensor is positioned at the memory element so that it provides a signal to the processor indicative of the magnetization of the memory element.  Preferably the signal is provided to the processor both as a discrete (polled) input and also as an interrupt.  A solenoidal winding is provided around the memory element.  The processor has an output which, when asserted, causes a substantial current to flow through the winding, whereby the memory element is demagnetized.  Alternatively, a reed switch is employed to sense movement of the rotor past a particular angular position. A flip-flop provides a bistable latch backed up by a lithium cell, and the output of the flip-flop provides a datum for the processor.  An interrupt routine is provided responsive to the signal from the second sensor, so that during a routine franking cycle the processor responds to the interrupt, makes record in nonvolatile memory of the occurrence of the printing cycle, and energizes the winding flip-flop reset.  This interrupt routine is executed for each franking cycle when power is continuously available.

Title: Sensor coil for low bias fiber optic gyroscope
Inventor: CORDOVA AMADO
IPC: G01C19/72
Filed: 1994-07-25
Abstract: A sensor coil for a fiber optic gyroscope.  The coil is formed on a spool of carbon composite material or of another material whose coefficient of thermal expansion approximates that of the overlying windings of the glass optical fiber.  The windings are potted in an adhesive material.  Various bias effects are addressed by the coil design.  The close matching of the thermal expansion characteristics of the spool and the fiber windings as well as proper selection of the coil potting material minimizes the Shupe-like bias caused by thermal stress that would be otherwise exerted by a standard metallic spool.  By careful selection of potting material (particularly its modulus of elasticity) vibration-induced bias, coil cracking, degradation of h-parameter and temperature-ramp bias sensitivity are also minimized.
