Patent CA-2179210-A1 (CA)
Inventor: BLODGETT JAMES RUSSELL
IPC: H01P1/161
Filed: 1996-06-17
Abstract: Disclosed is a cross-polarization cancellation apparatus and method particularly useful in a frequency reuse system, including a dual-polarized receiving system that receives a first electromagnetic signal having frequencieswithin a given frequency channel, which signal is transmitted from an external source at a first polarization. The receiving system also receives a second signal having frequency components within the given frequency channel which was transmitted at a second, different polarization. Received cross polarized energy of the second signal is cancelled by employing an antenna for receiving the first and second signals and for providing first and second antenna output signals containing received energy arriving at the antenna at the respective first and second polarizations. A novel circuit arrangement applies the antenna output signals to a combiner at an optimized relative amplitude and phase to substantially cancel the received cross polarized energy of the second electromagnetic signal.

Inventor: FERRARI FRANCO
IPC: F16B13/04
Filed: 1996-07-05
Abstract: A unit (10) for fastening iron fittings (43) to furniture parts, comprises an expansion plug (11) which axially receives a pin (12) rotatable between an insertion position and an expansion position of the expansion plug. The pin has a radial surface (34) designed to imprison an iron fitting between it and an opposing top end of the expansion plug. The radial protrusion defines a flat surface (34), substantially perpendicular to the axis of the pin, which extends partially over a coupling seat (35) formed in the opposing top end (14) of the expansion plug around the passage (13) for insertion of the pin in the expansion plug, the bottom (36) of the seat forming a surface facing the flat surface of the radial protrusion, the slot (35) having a side wall (38) facing a corresponding side wall (39) of the pin. The seat (35) can thus receive a substantially complementary portion provided on the iron fitting in correspondence with a hole in the latter for the passage of the pin.

Title: Colour printing process and product
Inventor: BERNASCONI MATTHEW
IPC: B41J2/525
Filed: 1995-04-05
Abstract: A seven colour separation process is provided in which, as well as the conventional Cyam, Magenta, Yellow and Black (CMYK) separations traditionally used in the four colour printing process, additional Red, Green and Blue (RGB) separations are produced on a conventional scanner. The additional separations are produced using the Cyan, Magenta and Yellow channels of the scanner to measure Red, Green and Blue absorption characteristics of the source and to compensate the measured densities such that the separations represent a range of print densities from 0.0D to 2.0D corresponding to densities in the source m the range 1.0D to 3.0D. The transfer duration is also compensated for the compression which takes place in the preparation of the CMYC separations.

Filed: 1996-12-20
Abstract: Pour confiner un éventuel déversement d'hydrocarbures lors d'un transbordement d' hydrocarbures entre un navire et un quai, ou de navire à navire; la présente invention propose une barrière à être montée sur une poutre en H fixée au quai, le long de laquelle la barrière peut se déplacer verticalement selon le niveau d'eau, à l'aide d'un flotteur. Cette barrière est mobile et amovible; de type mécanique, pneumatique ou hydraulique, pouvant être opérée et déclenchée par un seul homme. A la barrière mécanique est fixée une toile imperméable permettant de contenir les hydrocarbures; un ressort pousse un sabot à se coller à la paroi du navire à l'aide d'un aimant, ou coulisse sur la paroi du navire à l'aide de billes. Une alternative hydraulique bloque la diffusion d'hydrocarbures par la création d'un courant. Une alternative pneumatique utilise un rideau de bulles qui, lorsqu'elles  éclatent à la surface maintiennent prisonniers les hydrocarbures; en formant une barrière de courant. Il est ensuite facile d'enlever la nappe d'hydrocarbures emprisonnés.

Patent CA-2194637-A1 (CA)
Inventor: TOLEDO GEORGE F
IPC: E05F3/10
Filed: 1997-01-08
Abstract: A door closer having a spindle and cam arrangement for driving a cam plate longitudinally within a housing filled with oil, and dual rods connected to the cam plate at one end and to two pistons respectively at an opposite end. The pistons are reciprocal within cylinders having speed valves in flow communication to opposite sides of the pistons. Dual springs are arranged, one around each rod and compressed between the pistons and a fixed compression plate within the housing. A single adjusting screw extends from a front end of the housing to a threaded central aperture of the compression plate. Rotation of the adjusting screw sets the initial spring compression force of the return springs which influences the rate of closure of the door and the preload force of the door to the door frame.

A second distance, denoting the distance between outer edges of the complimentary pads is selected as the maximum distance btween outer edges of the terminals of anticipated surface mount components.  Manufacturing tolerances may be incorporated into each of these dimensions.  A design process is described which considers the dimensions of surface mount components which are likely to be substituted and manufacturing tolerance which may be added to or substracted from the dimensions of the uni-pad.

Patent CA-2200875-A1 (CA)
Inventor: STEWART BARBARA J
IPC: C09D11/00
Filed: 1995-10-03
Abstract: Provided is an ink-jet ink comprised of water, a pigment, a polymeric electrolyte, preferably a sodium, potassium or lithium salt of a polymeric carboxylic acid, a polyhydric alcohol and a stearate, preferably aluminum stearate. The presence of the stearate, particularly in combination with the polymeric electrolyte, provides one with an ink-jet ink which upon printing makes a perfectly round dot located only on the surface of the paper. The image also dries very quickly, is of high density and is waterfast. Printing problems are also avoided, such as plugging. The process for preparing the foregoing ink-jet ink comprises comminuting a formulation containing the components followed by a separation step. The separation step is important to provide a stable dispersion of the ink formulation.

Title: A wide band video signal denoiser and method for denoising
Inventor: HWA CHEN
IPC: G01S7/02
Filed: 1997-07-02
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.
