Abstract: A method and apparatus for high speed denoising of an input signal received by a radar warning receiver (RWR) system. The novel system digitizes the input signal into sample windows each having a number of sample data points. The novel system includes a signal transformation processor system which convolves Haar wavelet basis functions across individual time segments of the input signal to produce sets of coefficients .      Signal noise is poorly represented by the selected Haar wavelet basis functions while expected pulse signal characteristics are well represented by the basis functions. Within the wavelet transformation process, a plurality of frequency resolution levels are simultaneously determined, each frequency resolution level having a fixed number of correlation coefficients equal to the number of sample points in the sample window. Each coefficient also corresponds to a different basis function, or a same basis function applied to a different time segment. Each level contains a different number of represented frequency bands and a different number of time segments per band. For each level, the level's coefficients are sorted into coefficient maps and the largest coefficients are selected from each map. The coefficient map best packaging the input signal energy is then selected. The coefficients of the best coefficient map can be used to (1) reconstruct a denoised digital or analog signal using a re-transformation for application to a video pulse processor for threat characterization or (2) to produce a digital report indicating vital pulse information including leading edge pulse position, pulse amplitude, pulse duration, etc.

Abstract: L'invention décrit une sonde (10) à compensation de pression du matériau de moulage et de température, destinée à un appareil de moulage par injection (13). La sonde se compose d'un corps télescopique (34, 35) à deux parties, l'espace entre les deux parties (32) étant rempli par un matériau de moulage. La dilatation thermique longitudinale, qui posait auparavant des problèmes d'étanchéité, modifie seulement l'étendue du chevauchement du corps télescopique. La pression du matériau de moulage est appliquée de façon égale sur les deux parties composant la sonde, ce qui tend à améliorer l'étanchéité. L'espace rempli par le matériau de moulage présente une section supérieure à celle de toutes les sorties et de tous les passages.

Abstract: A gas monitor includes an infra-red source 5 enclosed within a housing 2 having inner surfaces which are reflective. Radiation emitted from the source 5 reflects off ellipsoidal surfaces 7 and 8 and intermediate planar surfaces 3 and 9 to be focussed at a sensor 6, being reflected five times. Radiation is absorbed by gas within the housing and a comparison of the source intensity and detected intensity gives a measure of the gas concentration. Use of ellipsoidal reflective surfaces 7 and 8 directs emitted radiation along a plurality of routes having substantially the same path length, hence giving an accurate measure of the gas concentration with a compact device. In another embodiment, off axis parabolas are used to direct the radiation through the gas.

Title: Electrodialysis apparatus
Inventor: MANI K N
IPC: C02F1/469
Filed: 1997-12-17
Granted: 2006-07-25
Abstract: A gasket for an electrodialysis cell assembly has a series flow path comprising a plurality of flow path sections joined by restrictor sections. Each of the flow path sections has a relatively wide width. The restrictor has less than the wide width so that a fluid flowing in the series flow path must increase its velocity as it flows through the restrictor. The result is that the fluid exiting the restrictor cause turbulence and agitation in the flow path sections. Manifold holes are located at opposite ends of the series flow path. A rigid port is positioned between each of the manifold holes and the ends of the series flow path. The successive cells of the assembly are defined by a pair of bipolar membranes with cation and/or anion exchange membranes between them. One of the gaskets is located between each two of the membranes.

Title: Printing press having cantilevered self-driven cylinders
Inventor: KULESZA RADOSLAW
IPC: B41F13/14
Filed: 1998-03-04
Granted: 2007-07-31
Abstract: In order to facilitate removal and replacement of blanket and impression sleeves in a rotary offset printing press, the blanket and plate cylinders are supported in cantilever fashion. The cantilevered cylinders allow axial removal and replacement of the blanket and impression sleeves without temporary support of the cylinder and without removal of any bearings. Each cylinder is rotatably supported on a cantilevered support shaft having a bore therethrough. A drive shaft operatively connected to a drive motor extends through the support shaft bore and engages the inner surface of the generally hollow cylinder. A blanket or impression sleeve mounted on the cylinder is removable using compressed air, which is routed through a bore in the drive shaft and through a plurality of radially oriented passage in a flange on the end of the drive shaft. Each radial passage communicates air to an exit port on the surface of the cylinder, which introduces enough air between the cylinder and the sleeve to permit the sleeve to slide freely for axial removal and replacement.

Abstract: A device is disclosed, for use with a snow blower being of the type having an auger, and allowing it to operate while moving backwards.  The device principally consists of a concave blade mounted on a snow blower, which pivots between an operative position where the blade extends close to the ground and the concave surface of the blade extends in front of the auger in such a way that the blade scrapes the snow and directs it towards the auger when the snow blower is lifted up to let the snow pass under it and moves backwards, and an inoperative position where the blade is raised to a height sufficient to let the snow reach the auger when the snow blower moves forwards.  A snow blower equipped with a device as defined above, for operating while moving backwards, is also disclosed as well as a method for blowing snow with a snow blower equipped with that device.  Although the device has been designed to fit on a removable snow blower mounted on a motorized vehicle, it could be adapted to any type of snow blower having an auger.

Abstract: Antérieurement, les réflecteurs excentrés des antennes paraboliques étaient alimentés par un signal passant par un cornet ondulé de manière à optimiser la distribution du champ et la polarisation au niveau du réflecteur.
