IPC: C09J7/38
Filed: 1995-09-15
Abstract: A method and apparatus for simultaneously coating multiple thin layers of relatively viscous fluids, including pressure sensitive adhesives (PSAs), onto a moving substrate. The method of the present invention comprises the adjustment of the pressure gradients in the interface region between two confluent flows so as to avoid recirculation therein. In particular, the pressure gradient along the middle lip is regulated so as to not be excessively positive, in order to position the separating line between the top and bottom flows at a particular point on the die lips, thus enhancing stable flow. In the apparatus of the present invention, a step configuration is formed on the die lips so that the downstream lip steps away from the web in the direction of web travel. In another aspect of the invention, the pressure gradient at various locations in the bead is controlled by beveling the upstream and downstream lips. In yet a further aspect of the present invention, the viscosities of the two liquids being coated are matched at therelevant shear rates to promote good coating quality.

Title: Method of generating electrical energy from regenerative biomass
Inventor: JOHNSSEN WOLF
IPC: H01M8/06
Filed: 1995-08-29
Abstract: The invention concerns a method of generating electrical energy from biomass which is produced in a biomass-production module. The biomass is gassified in a reformer module to form a hydrogenous crude gas from which a purified fuel gas with a high hydrogen content is formed in a crude gas processing module, electrical energy being generated from the purified fuel gas in a converter module. In this case, biomass with low sulphur and chlorine contents is produced by suitable fertilizing of plants. The reformer module operates with at least one allothermic reformer, the dwell time of the biomass and/or crude gas in the reformer and the pressure and temperature therein being set so that alkali compounds can be removed from the reformer with any ash produced. Tar is gassified in the reformer to form carbon monoxides and hydrogen. A purified fuel gas containing fewer than 1 % carbon monoxides is produced in the crude gas processing module. The purified fuel gas is converted into electric current by at least one PEM fuel cell, the operating temperature of the fuel cell, the water content of the purified fuel gas and the pressure of the purified fuel gas being adapted to one another so as to produce an optimum flow density.

Title: Method to improve data obtained by a radar
Inventor: HELLSTEN HANS
IPC: G01S13/90
Filed: 1995-11-10
Abstract: The present invention relates to a method of improving data obtained by radar by interpolation over frequency bands jammed by narrow-band interference, at which the following steps (A)-(J) are carried out. (A) it is determined what frequency values are affected by narrow-band interference. (B) Every radar return which is continuously connected in time and represented by a time-discrete real or complex signal f(t i), containing N sample, i=1,2,...,N, is Fourier-transformed into a frequency-discrete function F(.omega.i), given by N sample. (C) A series of integers N1, N2,...,N M is fixed, such that 1<=N1<N2<...<N M<N. (D) The signal processing device sets F k(.omega.i)=F(.omega.i) outside narrow-band interference and F k(.omega.i)=H k(.omega.i) within intervals having narrow-band interference. (E) H1(.omega.i) is equated to 0 and H k(.omega.i) for k>=2 is constructed according to the following steps (F)-(H). (F) F k-1(.omega.i) is inversely Fourier-transformed into a time-discrete function f k-1(t i). (G) The signal processing device sets h k(t i)=f k-1(t i) for i=1,2,...,N k-1, wherein ¦f k-1(t i)¦ constitute the N  k-1 greatest values of ¦f k-1(t i)¦ and h k(t i)=0 for the remaining N-N k-1 values of the function. (H) h k(t i) is Fourier-transformed into a frequency-discrete function H k(.omega.i). (I) Steps (D)-(H) are repeated M times, wherein 1<=k<=M. (J) F NM(.omega.i) is inversely Fourier-transformed to give the finally filtered radar return f NM(t i).

Title: Sand exclusion liner for use in a wellbore
Inventor: BOHME CALVIN G
IPC: E21B21/00
Filed: 1997-08-13
Abstract: A conventional screened liner is modified to enable fluid circulation through its length when working it toward a landing position in a horizontal wellbore. At surface, a sleeve of heat-liquefiable sealant (such as wax or tar) is formed internally in each perforated liner joint to blind the liner openings. The sleeve may have a central longitudinal bore formed therethrough or alternatively the sleeve is bored out to fully re-open the joint bore. In either case, the bore through the blinded joints enable circulating the liner into the wellbore. Once the liner is in place, the sealant can be removed by circulating steam past it to liquefy it. By providing bore-forming blinded screen joints, it is now possible to circulate through the entire length of liner to remove sand blockages without reversing fluid flow through the liner openings.
