Title: Regular division of melt flow in extrusion of blown films
Inventor: CREE ROBERT E
IPC: B29C48/34
Filed: 1997-08-26
Granted: 2006-03-21
Abstract: An extrusion die having a plurality of die layers stacked one upon the other in a direction generally parallel to the central axis. Each of the layers has an annular flow distribution ring (40) having an outer generally cylindrical surface and an annular feed ring surrounding and engaging the outer surface of the distribution ring (42, 42d). At the engaged surfaces of the feed and distribution ring, the flow from the feed ring is divided into a number of substantially equal flow portions. Seals (43a, 43b) between adjacent engaged surfaces confine the flow between the circumferential surfaces of the feed and distribution ring. Half of the flow portions are directed to a recombination region (45, 46) on one side of the distribution ring (42d}, and half are directed t o a recombination region (45, 46) on the other side of the ring (42d). In recombining, weld lines are formed in high flow areas minimizing t he deleterious effect of polymer degradation. Subsequently, the flows on the opposite sides of the distribution ring (42d) are recombined su ch that the weld lines from one half are first modified to exhibit lower flow and then are layered with non-weld line portions modified to exhibit higher flow from the other half. This further minimizes the negative effect of weld line areas. Flow from the two sides is regularly divided to yield even distribution of the combined flows.

Abstract: The present invention is a carrier bracket and rack assembly for external cargo carrying by vehicles. The carrier bracket is permanently attached to the vehicle behind the license plate using common fasteners through the existing license plate mounting holes. The license plate then re-attaches to this carrier bracket. The carrier bracket is channel-shaped with the rearward-extending channel sides being wide enough apart to accept a standard-length license plate therebetween and extending rearward enough to clear the vehicle's bodywork.  The outboard ends of the channel sides terminate with fittings suitable for the separate rack assembly to solidly connect to the carrier bracket. The rack assembly is adapted to the particular cargo to be carried. A variety of racks for bicycles, skis, sports equipment and the like, or for hauling small trailers, wagons and the like, may be quickly attached and detached from the carrier bracket. In particular a bicycle carrier rack having supporting members that engage the bicycle wheel at a point behind the front fork is disclosed.

Abstract: A hydro-pneumatic axle spring suspension system for the driven axle of an agricultural utility vehicle, in particular for the front axle of an agricultural tractor, is described, which contains at least one hydraulic cylinder arranged between the vehicle chassis and axle body. The rod end chamber and the piston end chamber of the hydraulic cylinder are each connected with at least one accumulator. Furthermore a valve circuit supplied by a hydraulic pump is provided for the control of the level, which controls the pressure of the accumulators as a function of the load on the axle body. To improve the operating and spring characteristics of the utility vehicle it is proposed that the mechanical and hydraulic components be designed for a spring suspension under maximum load of the axle body. The valve circuit is configured and controlled in such a way that in the accumulators an adequate pressure is constantly maintained in order to make possible a spring suspension of the axle body under all load and operating conditions of the vehicle.

Abstract: Light wave diffraction device formed of a dielectric layer (4), a reflecting structure (12) arranged on one lower face (10) of said layer, and a diffraction grating (8) arranged on one face (6) of said layer. The height (H) of the layer is selected so as to substantially satisfy the resonance condition for a leaky mode in said layer for at least one given incident wave having a wavelength .lambda. and a determined angle of incidence. Next, the diffraction grating has a spatial period selected so that the incident wave is diffracted essentially along the first negative diffraction order and at an angle of diffraction different to the angle of incidence (outside the Littrow condition). In particular, the invention provides that either the angle of incidence, or the angle of diffraction is high, i.e. relatively close to 90° from the direction perpendicular to the diffraction grating. This diffraction device allows a very high diffraction efficiency, of up to 100%, to be obtained, even when the incident wave is grazing.

Abstract: A process for providing a isoflavone rich protein isolate is provided, along with the isoflavone rich protein isolate produced thereby. A vegetable material containing protein and at least one isoflavone compound is extracted with an aqueous extractant having a neutral pH. The protein and isoflavones are extracted into the extractant, and the extractant containing the protein and isoflavones is separated from insoluble vegetable materials to form a protein extract. The pH of the protein extract is adjusted to about the isoelectric point of the protein to precipitate the protein. The extract containing the precipitated protein is cooled to a temperature of from 30°F to 90°F, and then the protein is separated from the extract. The cool separation temperatures unexpectedly significantly increase the concentration of isoflavones recovered in the separated protein, while the neutral extract pH inhibits loss of protein normally observed at cool or cold separation temperatures.

Title: Base station (apparatus and method) with directivity and transmission power control
Inventor: HIRAMATSU KATSUHIKO
IPC: H04B7/04
Filed: 1999-03-23
Granted: 2003-12-23
Abstract: Base station 11 transmits downlink signal A to mobile station 12A with wide directivity and transmits downlink signal B to mobile station 12B with narrow directivity with an overlap with downlink signal A.      Despreader 104 of mobile station 128 measures the reception power of downlink signal A and despreader 105 measures the reception power of downlink signal B. The respective reception power measurement results are carried on uplink signal B by frame assembly section 106 and reported to base station 11. Base station 11 determines whether the directivity orientation is matched or not based on the transmission power ratio and reception power ratio and controls the directivity and transmission power of the transmission signal based on the result. Thus, base station 11 precisely determines whether the transmission power and directivity of downlink signal H are accurate or not and modifies the transmission power and directivity.

Abstract: A method for estimating the optical flow between a plurality of images is provided. The method includes obtaining a motion orientation component and a motion magnitude component. Determining the motion orientation component includes creating, a first graph using spatio-temporal derivatives of the plurality of images, solving for a first maximum-flow in the first graph to thereby obtain a first minimum-cut therefrom, and computing the motion orientation component from the first minimum-cut. Determining the motion magnitude component includes creating a second graph using spatio-temporal derivatives of the plurality of images and the motion orientation component, solving for a second maximum-flow in the second graph to thereby obtain a second minimum-cut therefrom, and computing the motion magnitude component from the second minimum-cut. The motion orientation component and the motion magnitude component together comprise the estimate of the optical flow between the plurality of images. The method properly models errors in the measurement of image derivatives while enforcing a brightness constraint, and efficiently provides a globally optimal solution to the optical flow in the context of the model.
