Patent CA-2008700-C (CA)
Title: Hybrid seed production
Inventor: BRIDGES IAN GEORGE
IPC: C07K14/47
Filed: 1990-01-26
Granted: 2006-01-10
Abstract: Male sterility is imparted to a plant by a cascade of gene sequences which expresses a protein which disrupts the biosynthesis of viable pollen.      Expression of the disrupter protein is restricted to male parts of the plant by an upstream promoter sequence which is specific to male flowers, the male specific promoter being under control of an operator sequence. The cascade also includes a gene encoding a repressor protein specific for that operator. Expression of the repressor protein is under control of a chemically inducible promoter which is inducible by the application to the plant by, spraying or like process, of an exogenous chemical. In the absence of the exogenous chemical inducer, no repressor protein is expressed, resulting in expression of the disrupter protein and, consequently, male sterility. Fertility may be restored to the plant, when required for maintenance of the line, by spraying with the inducer, resulting in expression of the repressor which binds the operator and inhibits expression of the disrupter protein.

Title: Method for continuous casting of steel
Inventor: SUZUKI MIKIO
IPC: B22D11/115
Filed: 1990-03-02
Granted: 1996-12-31
Abstract: A method for continuous casting of steel comprises charging molten steel from a tundish into a mold through exit ports of an immersion nozzle, introducing a magnetic field vertically to a flow of the molten steel from the exit ports by the use of at least a pair of direct current magnets which are arranged on the outer side of copper plates on the wide side of tile mold, the immersion nozzle being placed between the direct current magnets and polarities of magnetisms on the top side of the magnets being the same, and casting the molten steel at a predetermined casting rate. One magnetic pole of the direct current magnet is positioned at an upper end of copper plate on the wide side of the mold and the other magnetic pole being positioned at lower than the exit port of the immersion nozzle and on the outer side of copper plate on the wide side of the mold. The immerison nozzle has two exit ports, each of which has an angle of 15 to 45° downward. The direct current magnetic field is controlled within the range of 1000 to 4000 gauss.

Title: Perceptually-adapted image coding system
Inventor: JOHNSTON JAMES D
IPC: H04N19/94
Filed: 1990-04-19
Granted: 1996-02-06
Abstract: An image-coding system reduces image data redundancies and perceptual irrelevancies through progressive sub-band coding. The image is separated into aplurality of sub-bands. From this sub-band information, a perceptual metric, based on the properties of the sub-band filters, quantizer error distribution, and properties of the human visual system, is determined which provides the maximum amount of coding noise that may be introduced to each pixel in every sub-band without causing perceptible degradation of the coded image. This perceptual metric is used to adjust the quantizer used in encoding each sub-band signal. In addition, redundancy in the output of the quantizer is reduced using a multidimensional Huffman compression scheme.

Title: Time division communication system frame changeover arrangement
Inventor: DRESHER KEVIN M
IPC: H04J3/14
Filed: 1990-09-26
Granted: 1995-03-28
Abstract: A frame organized time division multiplex communication system includes a central office and at least one remote terminal. A time division linkconnected between each remote terminal and the central office carries signals organized in time division multiplex frames. The central office determines the time division multiplex link frame format. Each remote terminal has at least one interface connected to the time division link that multiplexes signals into the time division multiplex frames, demultiplexes signals from the time division multiplex frames and monitors the time division frames from the time division link for in-frame and out-of-frame operation. An interface controller in the remote terminal determines the frame configuration of the interface multiplexing and demultiplexing. The controller identifies interfaces exhibiting out-of-frame operation and automatically switches the identified out-of-frame interfaces to an alternate frame configuration. The remote terminal frame configuration is thereby adjusted to correspond to a change in time division link frame format.

Title: White balance adjusting apparatus for automatically adjusting white balance in response to color information signal obtained from image sensing device
Inventor: HARUKI TOSHINOBU
IPC: H04N9/73
Filed: 1990-11-16
Granted: 1999-02-23
Abstract: 64 regions are set on an image sensed picture of a video camera, where evaluating values r ij, b ij, and y ij are obtained by averaging color difference signals R-Y and B-Y and luminance signal Y obtained from an image sensing signal for over 1 field period by each region.  When determination is made that the difference in the evaluating values between two continuing regions do not exceed a predetermined value according to the obtained evaluating values, that is, when determination is made that continuing regions have the same color, the weighing amount of the color evaluating values of a corresponding region is reduced in producing gain control signals regarding the color difference signals.  As a result, the effect of objects of the same color towards white balance adjustment is reduced.

Title: Cationic resin containing blocked isocyanate groups suitable for use in electrodeposition
Inventor: VALKO JOSEPH T
IPC: C09D175/04
Filed: 1991-06-14
Granted: 1996-05-14
Abstract: A cationic resin containing blocked isocyanate groups which is suitable for use in electrodeposition is disclosed.  The cationic resin is derived from an epoxy resin and contains in the resin molecule cationic salt groups, active hydrogen groups and blocked isocyanate groups.  The blocked isocyanate groups are incorporated into the resin molecule by reacting the epoxy resin with a compound selected from the class consisting of mercapto compounds and acid group-containing compounds where the compounds also contain blocked isocyanate groups.  The resin can be formulated into an electrocoating composition which is free of lead and yet provides outstanding corrosion resistance when electrodeposited over steel substrates.  The outstanding corrosion resistance can be attained when the substrate has not been given a chrome rinse which is conventional in pretreating the steel substrate before electrodeposition.

Granted: 2002-10-01
Abstract: An electromagnetic lock assembly (100) has longitudinally extending interlocking protrusions (22) and recesses (12) in the magnet (20) and magnet housing surfaces.
