Title: Potentiometric determination of azide ions or hydrazoic acid
Inventor: HORN GERHARD
IPC: G01N27/403
Filed: 1990-04-09
Abstract: The concentration of azide ions (N3<->) or hydrazoic acid (HN3) in a test solution, is determined by a pH electrode and a reference electrode both surrounded by a hollow body 5, the wall of which is partially formed by a semi-permeable diaphragm 2, which dips into the test solution 1, the interior of the hollow body 5 being filled with an inner filling solution 3, which is produced by dissolving 0.2 to 5 x 10<-3> mol of an easily soluble azide in one litre of water. The test solution has a maximum pH value of 2. Between 5 x 10<-3> and 1 mol per litre of a further salt may be added to the filling solution; the further salt being completely soluble in the solution and unreactive with azides or hydrazoic acid. Its purpose is to render the ionic strengths of the test and filling solution equal. A gas-sensitive sensor of the above construction is also claimed. <IMAGE>

Title: Active clearance control with cruise mode
Inventor: SCHWARZ FRED M
IPC: F01D11/24
Filed: 1990-06-18
Abstract: Flow of cooling air to a thermal clearance control system in a gas turbine engine is selectably scheduled between a normal power level versus clearance schedule 14 and an increased efficiency cruising schedule 26. Selection of the cruising schedule 26 is accompanied by a limitation on the rate of engine power increase during the period when the cruise schedule is selected. Selection and deselection of the cruising schedule 26 may be dependent upon engine speed or power demand setting, ambient air pressure or temperature, altitude, engine pressure ratio, operator input or the time since the last engine power level demand change. <IMAGE>

Title: Testing erbium doped optical fibres.
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G01M11/00
Filed: 1991-01-26
Abstract: In optical fibre systems incorporating a number of fibre amplifiers the latter should, ideally, have the same characteristics, e.g. the same erbium concentration along their lengths. To test the uniformity of erbium concentration of a long length of erbium doped fibre before it is cut up into individual fibre amplifier lengths an OTDR technique is employed. In order that such a long length of erbium doped fibre can be tested the OTDR source wavelength is chosen to be off resonance of an erbium absorption band, in particular on the short wavelength side of the absorption peak.

Title: A method of operating a rapid restrike metal halide lamp
Inventor: HEINDL RAYMOND ALBERT
IPC: H05B41/38
Filed: 1991-04-24
Abstract: A method of operating a rapid restrike metal halide lamp is disclosed which is particularly suitable for sports stadium lighting applications. The rapid restrike metal halide lamp (10) has an arc tube (32) containing constituents which require a waveform (52) having a relatively high voltage and at a relatively high current in order to rapidly restrike the arc tube after the lamp has experienced a power interruption so as to initiate a sustaining arc condition of the arc tube. The waveform (52) comprises a train of pulses each having decaying high frequency oscillations. Such a relatively high waveform (52) is routed to the arc tube by means of a two path arrangement comprising a conductive base (14) at the bottom of the lamp and an insulative cap (22) at the top of the lamp. This two-way path substantially reduces and even eliminates any arcing condition within the confines of the lamp. The rapid restrike metal halide lamp may have a keep-alive heater (46) arranged around at least a portion of the arc tube so as to assist in the rapid restriking of the lamp after the lamp has experienced an extended shut-down or cool-dawn condition. <IMAGE>

Title: Detection and imaging in biochemical assays using phosphorescent screens
Inventor: BERS GEORGE
IPC: G01N33/58
Filed: 1991-07-12
Abstract: Immobilized macromolecules, such as proteins or nucleic acid sequences (12), are tagged with labels (13) which induce a chemiluminescent reaction in a liquid-phase substrate (15). As the reaction is occurring, the substrate is exposed to a phosphorescent screen (16) which absorbs the chemiluminescent emission in an image of the pattern formed by the macromolecules. The absorbed energy is then released and read, providing qualitative and optionally quantitative information regarding the immobilized macromolecules. Distinct labels, which react with a mixture of chemiluminescent substrates to emit light at correspondingly distinct wavelengths, may be used with a phosphorescent screen selectively excitable by light of said distinct wavelengths. By this method different macromolecules can be detected simultaneously. <IMAGE>

IPC: H01Q1/18
Filed: 1992-03-19
Abstract: In a stabilised antenna system, an inclination angle detector (52) is mounted on an AZ (azimuth) frame (26) and detects an inclination angle around an elevation (EL), and the elevation of the antenna (22) is controlled by a successive addition of the detected inclination angle to simplify a control algorithm. Furthermore, the inclination angle detector (52) includes a reciprocal combination filter (142) for combining outputs of an inclinometer (72) and a rate sensor (74). The reciprocal combination filter (142) includes two reciprocal filters (144, 146), and parameters thereof are adaptively controlled depending on frequency and amplitude of the inclination to ensure the reciprocity in a necessary frequency range. <IMAGE>

Title: Fluid-flow control apparatus
Inventor: GORMAN DEREK
IPC: G05D23/19
Filed: 1992-04-24
Abstract: A fluid flow control apparatus (1) for a central heating installation has a single hot water input (2) and two hot water outputs (3, 4). Flow through each output is controlled by two valve elements (8, 9) each having a plurality of slots (7, 22) formed therethrough. Linear movement of one of the valve elements (9) across the other results in the alignment of the slots and thus the opening of the valve. Wax filled chambers (32) (Fig. 2, not shown) are associated with respective ones of the valve elements (9) and are arranged to be heated and cooled such that the resulting expansion and contraction produced the linear movement to open and shut the valves. In a modification, the valve elements (9) are solonoid activated. <IMAGE>

IPC: H04W56/00
Filed: 1992-08-19
Abstract: The present invention presents an apparatus and method for recovering symbols in a data packet (101) transmitted to a receiver from a remote signal source (204) in a time-varying channel using multiple sampling points. In a digital cellular radiotelephone TDMA system, the receiver (202) performs a complex correlation on the desired slot sync word (DSSW) and the coded digital verification color code (CDVCC) in the data packet (101) and on the adjacent slot sync word (ASSW) in an adjacent data packet (102) to produce a first, second and third optimum sampling point, respectively. The data packet (101) is divided into four regions (A, B, C and D). The symbols in each region (A, B, C and D) are serially recovered using one or more of the multiple sampling points depending on the quality of the sampling point adjacent to each region (A, B, C and D). <IMAGE>

Title: Methods of determining triggering of an automatic braking operation
Inventor: RUMP SIEGFRIED
IPC: B60T8/00
Filed: 1995-03-31
Abstract: The invention relates to a method for determining the triggering sensitivity of an automatic braking sequence in a motor vehicle according to the driving situation. During a braking manoeuvre in a motor vehicle an automatic braking sequence is triggered when the rate of operation of the brake pedal exceeds a predetermined threshold. The automatic braking sequence resides in the fact that a brake pressure is generated greater than that corresponding to the brake pedal position. …<??>The object of the invention is to adjust the triggering sensitivity for the automatic braking sequence to the driving situation prevailing at the time of the actual braking manoeuvre and thus to permit a better distinction between emergency braking and deliberate, controlled braking. …<??>The object is achieved in that the triggering sensitivity is adjusted as a function of the nature or the time sequence of pedal operation by the driver. In so doing only the current braking manoeuvre and/or the pedal operations preceding this braking manoeuvre are taken into account.
