Patent CA-2241638-A1 (CA)
Title: Ntsc video signal receivers with reduced sensitivity to interference from co-channel digital television signals
Inventor: LIMBERG ALLEN LEROY
IPC: H04B1/68
Filed: 1998-06-23
Abstract: A video signal receiver with reduced sensitivity to interference from co-channel digital TV signals includes circuitry for selecting a vestigial sideband amplitude-modulation signal descriptive of a video signal, converting the selected VSB AM signal to an intermediate frequency signal, and amplifying the IF signal to provide an amplified IF signal. The VSB AM signal is selected from any single one of a plurality of channels which can contain co-channel interference from a digital television signal. The amplified IF signal is synchronously detected with respect to video carrier frequency for generating an in-phase synchronous detection response and for generating a quadrature-phase synchronous detection response. All frequency components of the quadrature-phase synchronous detection response above a prescribed frequency are phase shifted substantially 90° and are linearly combined with in-phase synchronous detection response for recovering lower frequency portions of the video signal, substantially free of artifacts from any co-channel interfering digital television signal. In some embodiments of the video signal receiver higher frequency portions of the video signal described in the full sideband of the VSB AM signal, but not in its vestigial sideband, are recovered by synchronously detecting the VSB AM signal after selective filtering to remove the pilot carrier signal component of any co-channel digital TV signal. The selective filtering avoids any artifact of such pilot carrier signal being generated when recovering higher frequency portions of the video signal. The lower and the higher frequency portions of the video signal are combined to obtain a fullband video signal.

Each summation unit (20) performs an addition on its two inputs while preserving the magnitude of their sum. Depending on the sign of one of the inputs, the two inputs are either added to each other or subtracted from each other. The sign bit of both inputs are checked in order to determine to add or subtract.

Title: Method for forming full-length cdna library
Inventor: HAYASHIZAKI YOSHIHIDE
IPC: C12N15/09
Filed: 1997-10-31
Abstract: Disclose is a method for making full-length cDNA  libraries, which is for making libraries of cDNAs having lengths corresponding to full lengths of mRNAs and comprises the following steps of; forming RNA-DNA  hybrids by reverse transcription starting from primers using mRNAs as templates, chemically binding a tag molecule to a diol structure present in the 51 Cap (7me G PPP N ) site of a mRNA which is forming a RNA-DNA hybrid, and separating RNA-DNA hybrids carrying a DNA  corresponding to a full-length mRNA from the RNA-DNA  hybrids formed above by using a function of the tag molecule. The present method is a method for preparing full-length cDNA libraries utilizing a method for labeling the 5' Cap site more efficiently than protein enzyme reactions, which is avoidable a decrease of a full-length cDNA synthesis efficiency caused by cleavage of mRNA, and can synthesize a full-length cDNA  more efficiently.
Patent CA-2271722-A1 (CA)
Title: Surface static reduction device
Inventor: MILES PETER
IPC: H05F3/06
Filed: 1997-11-14
Abstract: A radioactive static eliminator gun has a cartridge (7) connected to a high pressure air supply (8). Within the cartridge (7) a radioactive source (6) which generates alpha particles is located coaxially along the central longitudinal axis. The alpha particles collide with the high pressure air stream passing through the cartridge thereby generating ions. With this arrangement the ion concentration is greatest at the core of the air stream which ensures that the greatest number of ions is delivered to the surface requiring static elimination. The radioactive static eliminator gun provides improved efficiency in removing static and is particularly suited to use in paint spraying of metal surfaces where the electrostatic forces at the surface of the metal may not be strong enough to attract ions in the air stream emerging from the gun.

Title: Il-9 receptor variants, useful in treating and diagnosing atopic allergies including asthma and related disorders
Inventor: LEVITT ROY CLIFFORD
IPC: C12N15/11
Filed: 1997-12-02
Abstract: This invention relates to the diagnosis, treatment and methods for discovery of new therapeutics for atopic asthma and related disorders based on variants of Asthma Associated Factor (2). One embodiment of the invention is a variant of AAF2, wherein codon 173 is deleted resulting in the loss of glutamine 173 from the mature protein precursor. This single amino acid deletion results in a non-functional AAF2 protein and therefore the presence of this phenotype should be associated with less evidence of atopic asthma. Correspondingly, the lack of susceptibility to an asthmatic, atopic phenotype is characterized by the loss of glutamine at codon 173. The invention includes isolated DNA molecules which are variants of the wild type sequence as well as the proteins encoded by such DNA and the use of such DNA molecules and expressed protein in the diagnosis and treatment of atopic asthma.

Title: Premixing fuel injector with improved secondary fuel-air injection
Inventor: KORZENDORFER JOHN J
IPC: F23D14/02
Filed: 1999-06-07
Abstract: A premixing, tangential entry fuel injector (10) for a gas turbine engine features a secondary fuel-air injection insert (40) positively secured to a centerbody shell (38) by a braze joint (98). A secondary fuel supply tube (42), positively secured to both a centerbody base (36) and to the insert (40), is curved in at least two dimensions. In an exemplary embodiment, the tube is coiled into a spiral shape covering a single 360° cycle. During engine operation, the centerbody expands axially in response to elevated temperatures in the engine's interior, causing the insert (40) to be displaced away from the base (36). The curvature of the tube allows the tube to flex slightly to accommodate the displacement. Ideally the curvature of the tube is such that the tube's natural frequency is well above the maximum vibratory frequency that the tube will experience during engine operation.
