Patent EP-0286268-A2 (EP)
Inventor: LYON RICHARD K
IPC: B01D53/60
Filed: 1988-03-23
Abstract: The present invention is related to a method for preventing the formation of NH₄HSO₄ during the noncatalytic reduction of nitric oxide by ammonia or ammonia precursors in combustion effluents. The present invention is also related to a method for preventing the formation of H₂SO₄ in the absence of ammonia or its precursors. The formation of these corrosive substances is extremely detrimental. NH₄HSO₄ formation is a limitation upon the usefulness of nitric oxide reduction processes, particularly in boilers, furnaces, and other combustion devices. The formation of H₂SO₄ limits effective heat recovery in combustion equipment. 
     The present invention specifically teaches the use of methanol to reduce SO₃ in the effluent stream to SO₂. The noncatalytic reduction of SO₃ by methanol is selective in that a large fraction of the SO₃ is converted to SO₂, while on a percentage basis very little oxygen is consumed. In addition, the process of the present invention allows the amount of methanol to be limited such that significant amounts of carbon monoxide are not produced and emitted with the effluent stream. By eliminating SO₃, the formation of NH₄HSO₄ and H₂SO₄ can be blocked. 
     The present invention teaches contacting the methanol with the combustion effluent at a temperature ranging from approximately 500°C to about 950°C in order to assure proper   operation of the process. It is also important to limit the reaction time used so that the carbon monoxide produced by the methanol oxidation is not itself oxidized to carbon dioxide.

Abstract: A tamper evident seal for containers (62) having a plastic shrink sleeve placed (80) around the cap (78) and neck (74) and extending over the shoulder (70). A paper label (92) is placed over a portion of the sleeve to prevent the sleeve from being removed intact. The sleeve has zigzag, saw-tooth perforations (86) above and below a median line. The perforations are between the shoulder and cap of the container. When the cap is twisted and removed the plastic sleeve is randomly fragmented making it difficult, if not impossible to match in any attempt to reseal the container.

Abstract: A transdermal detection system for the detection of a target substance which migrates to the surface of the skin of a subject by diffusion comprises detector means and attachment means. The detector means includes at least one detector chemical contained in solution and capable of chemically reacting with the target substance as the target substance migrates to the skin surface of the subject to produce a detectable signal, and a barrier means for substantially preventing migration of the detector chemical into the skin surface of the subject. The attachment means maintains the detector means adjacent the surface of the skin of the subject.

Abstract: The invention relates to a method for detecting polarisation couplings localised in a double refraction guided optical system using a polariser, P, at 45 DEG  to the axes of the optical system, 2, which is placed at its exit, and followed by an interferometer, for example of the Michelson type, S, M1, M2, D in which one of the optical paths has a variable length. As a result of the length variation of an optical path, interference fringes appear over half the energy emitted; the difference in length of the optical paths when such fringes appear characterises the position of a localised polarisation coupling and the fringe contrast measured for this length difference characterises the amplitude ratio of the primary wave to the coupled wave. 
<??>Application, in particular, to the assembly of the components of a double refraction optical system.

Abstract: A charge pump circuit (21) for charging a capacitor (C₁,C₂) in response to a phase difference between first and second input signals comprises a constant current source (Q₃) for providing a first constant current (i₃); a constant current sink (Q₆) for absorbing a second constant current (i₆); circuit (11,12) for substantially equalizing the magnitudes of the first and second constant currents; and a switching circuit (Q₄,Q₅) for providing the first constant current and the second constant current flowing in opposed directions to the capacitor through an output terminal (T₂) of the charge pump circuit in response to the phase difference between the first and second input signals to produce a voltage level across the capacitor corresponding to the phase difference. In a phase locked loop system employing such a charge pump circuit, a phase comparator (4) produces a phase difference signal for controlling the provision of the first and second constant currents by the switching circuit to the capacitor. The capacitor acts as a loop filter (22) supplying the voltage thereacross as a control voltage to a voltage controlled oscillator (7) of the phase locked loop system.

Abstract: A control computation unit (20) includes a delay element (31) in addition to an integrating element (22) and a proportional element (23). The delay time (ε -STd ) of this delay element is selected, following the time necessary for due settling (namely, the time required for rendering a controlled variable to follow changes in a control variable command), or the time necessary to restore the controlled variable to the control variable command when a controlled object involved has incurred a certain external disturbance. In case there exist a computation delay time, a dead time, and/or a detection delay time, respectively in the control computation unit (20), controlled system, and/or a control variable detector, then the delay time is selected equal to one of the computation delay time, dead time, and the detection delay time, or the sum of these times. Additional provision of the delay element (31) with a delay time equal to the time desired for due settling to the control computation unit (20) results in settling within the time equal to the time desired for due settling the response.

Abstract: A communication system in which a plurality of multipoint connected satellite stations are connected via a down line and an up line to a master station. Each of the satellite stations monitors presence or absence of occurrence of an abnormality in the down line, judges whether the abnormality is present or not and, where the abnormality is present, informs the master station of the nature of the abnormality via the up line. In turn, the master station monitors presence or absence of an alarm indicating abnormality from each of the satellite stations, judges whether the alarm is detected or not and, where the alarm is detected, reads past record information concerning abnormality detection in the satellite station concerned and information on retraining execution time, then judges whether the down line is normal or not and, where the down line is normal, sends a training signal again to the down line to retrain a MODEM corresponding to the satellite station concerned. Accordingly, it is possible to quickly restore demodulation processing by each of the satellite stations to a respective normal status after a recovery of trouble in a down line.
