Patent FI-20031544-A (FI)
Inventor: LEE HENRY J
IPC: D21F7/08
Filed: 2003-10-22
Abstract: A papermakers fabric having a system of flat monofilament machine direction yarns 22,23 (hereinafter MD yarns) interwoven with a system of cross machine direction yarns 21a,21b (hereinafter CMD yarns). The MD yarns 22,23 have an aspect ratio of greater than 3:1. Furthermore the MD yarns are vertically stacked with at least paired upper 22 and lower 23 MD yarns which weave over and under CMD yarns 21a,21b in such a manner that when a lower MD yarn 23 weaves over a CMD yarn 21a an upper MD yarn 22 is weaving (or floating) over the lower MD yarn 23. This ensures that no knuckles are apparent on the upper surface of the fabric. The weave gives rise to a warp-fill in the range of 80-125%.

Abstract: Moving objects are detected with a radar by collecting samples of a received signal over an integration period. The terms of a match function contain a product of a sample of said received signal and a delayed-in-time, Doppler-shifted replica of a transmission and depend on parameters that describe an object that caused a reflection of the transmission. The most probable values of the parameters are found by maximizing the match function through Fourier transforming a vector consisting of terms of the match function. Those of said products that contain a non-zero contribution of said delayed-in-time, Doppler-shifted replica of a transmission are actually computed while the others of said products are zero Only non-zero blocks of the products count as final terms to the vector to be Fourier transformed that have nonzero value while intermittent blocks that have zero value are left out. The most probable values of the parameters are those that result from Fourier transforming the vector consisting of the final terms.

Abstract: 1,009,506. Gyroscopic apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec.19, 1961. [Dec.21,1960], No. 45447/61. Heading G1C. A pendulum, incorporating a gyroscope, is schuler-tuned by an electrical circuit and two of  such pendulums are used to control a horizontal platform which is preferably employed for inertial navigation. A pendulum 2, Fig. 1, is fixed to an input shaft 1 which also has a torquer 4 and gimbal 7 therein, gyroscope 5 having its inner gimbal 6 mounted in gimbal 7 so that its movement is opposed by a spring 8 which may be mechanical or electrical. On rotating shaft 1 and thus gimbal 7,the gyroscope 5 and inner gimbal 6 presses against the action of spring 8, to produce a deflection, as measured by pick-off 9, which is proportional to the angular velocity of the input shaft 1. The signal from pick-off 9 is differentiated at 11 amplified at 12 and fed to the torquer 4 as a signal proportional to the angular acceleration of shaft 1. By suitable choice of proportionality and amplifying factors schuler-tuning is achieved. In an inertial navigation system, Fig. 2, a gimbal mounted platform P is provided with two such pendulum devices P x , Py, having their input shafts at right angles to one another and in one embodiment the input shaft of pendulum P x  is aligned with the local meridian tangent direction whilst that of pendulum Py is aligned with the local parallel tangent direction. The P x  signal from pick-off CX x  representing the angular position of pendulum P x . is fed through resolvers RS 1 , RS 2 , and an amplifier, to servo motor SM 3 , whilst that from pick-off CX y  is fed through resolver RS 1  and an amplifier to servomotor SM 2 .<SP> </SP>The azimuth servo-motor SM 1  is controlled by gyroscope GA z , the latter having a torquer MG z  fed with the signal from pendulum P x  corresponding to that from pick-off 9, Fig. 1, multiplied by tan L where L is the angle of latitude. By integrating the outputs of pendulums P x , P y , allowing for the earth's rotation, and if necessary for the ellipticity of the earth, coriolis acceleration and height of the platform, the latitude and longitude are given. In another embodiment the input shaft of pendulum P x  is aligned with a predetermined meridian tangent or great circle tangent direction and the output is in terms of co-ordinates along the two input axes. Specifications 856, 685 and 945, 302 are referred to.

Abstract: 1,251,526. Freezing liquids; drying frozen materials. WESTERN ELECTRIC CO. Inc. 4 Dec., 1968 [6 Dec., 1967], No. 57508/68. Headings F4G and F4H.  In a method of producing a particulate material, a solution of the material is introduced into the lowermost region of a body of refrigerant liquid so that the solution is frozen and rises towards the surface of the liquid. As shown, solution from a pressurized bath 2 passes through line 6 to an atomizer 5 which injects droplets of solution into a body of refrigerant contained in a chamber 1, and the frozen droplets collect on the surface of the refrigerant beneath a partially immersed apertured screen 18. Chamber 1 has a jacket 1 which may be supplied with a heat exchange gas, e.g. nitrogen, through line 15, and atomizer 5 has a heater 10, the heater and the admission of said gas being controlled so as to prevent the solution from coalescing in or immediately above the atomizer. After completion of freezing, a further screen 17 is rotated by 180 degrees to define a spherical enclosure with screen 18, the refrigerator is drained through line 8 and a drying gas, e.g. air or nitrogen, is introduced at atmospheric pressure through line 8 while the enclosure 17, 18 is rotated about axis 19. The drying gas temperature is initially - 40 C. and is increased to - 5 C. Residual moisture is removed from the frozen material by successively reducing the pressure in the chamber, e.g. to 1 mm. Hg, while maintaining the initial temperature, e.g. -5C., raising the temperature by 5 C., introducing a dry gas to restore atmospheric pressure and repeating the cycle from the new initial temperature of 0 C. In a modification (Fig. 3, not shown) freezing is carried out continuously in chamber 1 which is connected to a plurality of freeze drying chambers, the screens 17, 18 being provided within the latter chambers. The process is suitable for use in the preparation of ferrites and other oxidic materials.
