Patent EP-0611972-A3 (EP)
IPC: G02B6/12
Filed: 1993-12-03
Abstract: An improved method for forming a Bragg grating in a photosensitive, 
optical waveguiding medium (e.g. optical fiber) by exposure to an 
interference pattern formed by 
overlapping beams of actinic radiation. When Bragg gratings are formed 
according 
to methods of the prior art, these gratings tend to exhibit 
reflectivity spectra having, 
in addition to a central peak, a generally undesirable series of 
subsidiary peaks (sidelobes). 
These subsidiary peaks are caused by a wave interference effect. The 
inventive 
method modifies or eliminates the subsidiary peaks by spatially 
modulating the 
average refractive index of the grating, or by spatially modulating the 
grating period.

Title: Fibre optic force measuring procedure
IPC: G01L1/24
Filed: 1993-01-18
Abstract: In order to obtain unique non-modulo-2 pi -independent measurement results, the fibre optic force measuring procedure, which is based on the voltage-induced birefringence of a monomode optical fibre (4), provides a compensation procedure for the phase differences, caused by the action of the force on the optical fibre (4) and the change in birefringence following therefrom, in the two linear modes of the light waves at the outlet end. According to one variant procedure, use is made as a compensation element of a liquid crystal cell whose birefringent effect is electrically controllable. The maximum of an autocorrelation function produced as an image and of the voltage value, associated therewith, at the liquid crystal cell is evaluated as a measure of the birefringence to be compensated, and consequently of the force acting. 
<??>In another basic variant procedure, the two component waves are guided by an optical component (15) having linearally spatially-dependent birefringence transverse to the direction of propagation of the wave fronts. As a result, the autocorrelation function can be obtained as a spatial coordinate and electronically recorded using a linear detector (16), for example a linear array. Under specific, defined preconditions, the location of the maximum in the autocorrelation function is a measure of the birefringence caused in the optical fibre (4) by mechanical stress, from which it is possible, in turn, to calculate the magnitude of the force acting on the force sensor (3).

Title: Improved sprayable portland cement-based fireproofing compositions.
Inventor: PERITO RICHARD P
IPC: B05D1/36
Filed: 1995-05-05
Abstract: Sprayable fireproofing compositions for structural members such as steel columns are provided, as well as a method of applying multiple coatings thereof. The compositions comprise a Portland cement-based material, stucco, a high density aggregate and an accelerator. The compositions eliminate the long setting times typical of Portland cement-based materials, and improve the hangability thereof. The product is produced by dry blending a mixture of Portland cement, a high density aggreagte, stucco (calcium sulfate hemi-hydrate) and optionally, a stucco set retarder and shredded polystyrene aggregate. Upon the addition of water, sprayable slurries are formed which can be pumped to the point of application. An accelerator is added in close proximity to the point of injection. The slurries adhere to the structural member in the slurried state and after setting to provide excellent fire and heat protection. Because of the relative quick setting time of the slurry upon spray application, multiple coatings can be applied within the same working day.

Title: Method of making a hollow fibre membrane
Inventor: JACOBS EDMUND PETRUS
IPC: B01D69/08
Filed: 1996-06-06
Abstract: A method of making a hollow fibre membrane comprises extruding a membrane-forming polymer solution through the annulus of the tube-in-orifice spinneret (12) to form a nascent hollow membrane (32), there being a lumen coagulant in the lumen of the nascent membrane, and the outside of the nascent membrane being contacted with an external coagulant (34) . The external coagulant has a solvent content which is such that, at the interface between the nascent membrane and the external coagulant, liquid-liquid phase separation rather than gelation is thermodynamically the favoured process, and the membrane is then subjected to a vapour-phase non-solvent environment to induce precipitation of the phase-separated polymer.

then notified of the available pre-paid return call through periodic callbacks to the
intended recipient or by alerting the recipient the next time the recipient makes a
call. The receiver of the message has the option of returning the call immediately or
at a later time within a time duration set by the caller.

Abstract: The regulator regulates an medium flow fed from a medium supply to a hydrostatic or aerostatic pocket of a bearing, threaded spindle or a guide. The regulator has pressure chambers separated from a control element moved against the force of a spring element. A first pressure chamber actuated with a first pressure level (p1) is connected directly to the medium supply. A second pressure chamber actuated by a second, lower pressure level (p2) is connected to the supply via a first resistor. A third pressure chamber actuated by a third pressure level (p3) corresponding to that in the hydrostatic or aerostatic pocket is connected to the pocket. The control element forms a variable second flow resistance between the second and third pressure chambers, which affects the flow fed to the pocket. The size of this second resistance is increased by the force of a first pressure chamber but is reduced by the effect of the spring force as well as the force of the second and third pressure chambers. A bypass (29) is provided with a third, preferably fixed, flow resistor (33). The third resistor is connected to the hydrostatic or aerostatic pocket and also, via the first resistor (21), to the medium supply.

Abstract: Described herein is a printing system for rendering marks on a recording medium receives a
multi-level grey scale pixel value representing a pixel having a first resolution. A processing circuit
(401, 402, 403, 404, 406, 407) generates a screened multi-level grey scale pixel value equal to
(G L  - V i ) + (S i  - Th)*Dmp Vi *Mod Eff  wherein G L  is the maximum grey level value of the pixel, V i  is equal to
the multi-level grey scale pixel value of the first resolution, S i  is equal to a screen value corresponding
to a position of the pixel, Th is the threshold value, Dmp Vi  is a video dependent dampening factor, and
Mod Eff  is a modulation multiplication factor, where G L  = 255 and Th = 128. An interpolator converts the
screened multi-level grey scale pixel value to a second resolution which is higher than the first
resolution, and a binarization circuit binarizes the converted multi-level grey scale pixel value so as to
output a binary signal and an error value, the error value having a resolution equal to the first
resolution. The error value is diffused to multi-level grey scale pixel values corresponding to pixels
adjacent to the pixel having the first resolution, and the binary signal is converted into a mark on the
recording medium.

IPC: G01M11/02
Filed: 1997-07-08
Abstract: A system and method in which the chromatic dispersion
characteristic, as a function of distance along a section of transmissive fiber, is
measured. First and second optical signals are launched into a fiber under test
to thereby generate, by a four-wave mixing process in the fiber, a probe signal.
Because of a wave-vector phase mismatch, the probe signal power oscillates
with a spatial frequency that can be measured as a function of distance in the
fiber. The intensity oscillations are measurable as, for example, temporal
variations in the Rayleigh backscattered light detected at the input end of the
fiber. According to the present invention, the dispersion parameter at one or
both of the first and second optical signal wavelengths, as a function of length
along the fiber, is derived directly from these intensity oscillation
measurements. From this information, it is possible to further derive maps at
other wavelengths of interest.
