Patent CA-2220219-A1 (CA)
Inventor: METZGER DONALD LYNN
IPC: H01R4/24
Filed: 1996-04-04
Abstract: An electrical connector which provides compensation for crosstalk includes a number of conductors positioned at least partially within an internal cavity defined by a housing. The elongate conductors are generally substantially parallel and laterally spaced and include a resilient contact portion at a first end and an insulation displacement contact portion at a second end. The elongate conductors include a pair of conductors, at least a portion of which are positioned in an overlapping, vertically spaced relationship. The portions of the pair of conductors which overlap are generally wider than the substantially parallel, laterally spaced portions of the conductors so as to thereby define respective compensating segments. The length of the compensating segments as well as the width of the portion of the compensating segments which overlap can be selected to establish capacitive coupling between the compensating segments so as to thereby compensate for crosstalk between the conductors. The elongate conductors can also include first and second conductors which extend in a substantially parallel, laterally spaced relationship from the respective first and to a predetermined crossover location. At the crossover location, the first and second conductors laterally cross without establishing electrical contact therebetween.

Title: Apparatus for igniting a propellant charge in a tool
Inventor: BOOTHBY TERRY A
IPC: B25C1/16
Filed: 1996-06-03
Abstract: A tool for driving a nail or other fastener is actuated by a caseless propellant charge (62) formed of combustible material that is transported into a combustion chamber (44) on a strip (64). The propellant charge (62) is ignited by striking a sensitizer portion (90) of the charge at an oblique angle. The ignition member (66) intermixes the sensitizer material (90) with an oxidizer layer (88) of the surface of the propellant charge (62), resulting in combustion of the charge. When ignited, the propellant charge (62) is compressingly interposed between an orifice plate (74) and a movable portion (80) of the combustion chamber. The orifice plate (74) includes a pedestal (78) with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge (62); insuring that ignition gases are forced through the charge (62). An annular C-shaped ring (82) is interposed between the orifice plate (74) and the movable portion (80) of the combustion chamber (44). When the charge (62) is ignited, the resulting gas pressure resiliently expands the annular C-shaped ring (82) and urges opposite axial ends of the C-shaped ring (82) into sealing relationship between the relatively movable components of the combustion chamber. Combustion gases are communicated through orifices (76) in the orifice plate (74) to a cylinder (40) where the gases force movement of a driver (42), which driver strikes and drives a fastener such a nail. The driver (42) is reciprocally movable within the cylinder (40) and is returned to its precombustion position by a gas spring return cylinder (17). The gas return cylinder (17) is mechanically interconnected to the driver (42) and contains a sealed gaseous fluid that is independent of and segregated from fluids in the combustion chamber (44). An assembly (60) for deaccelerating the driver includes a series of spaced and aligned progressively sized metal cup members (110, 112, 114) of progressively increasing mass, contact surface area and interface angles.

Inventor: MOSTER VINCENT M
IPC: A01D45/02
Filed: 1997-12-09
Abstract: A combine and corn harvesting head of the type for removing ears of corn from their associated stalks are disclosed herein.  The harvesting head includes a row unit for each row to be harvested by the combine while following a path through a field of corn to be harvested. The row units each include a stationary vertical surface and a continuous belt rotatably supported to provide a moving surface parallel to the vertical surface.  The row unit removes ears of corn from their respective stalks when the ears are engaged by both the moveable and the stationary surfaces.  More specifically, the movement of the moveable surface relative to the stationary surface rotates the ears relative to the stalks (i.e. rolls the ears along the stationary surface) to remove the ears and to convey them to the conveying auger of the harvesting head.  The ears are then conveyed into the combine where they are threshed to remove the kernels of corn from the cobs of the ears.

Filed: 1996-10-10
Abstract: A wooden desk incorporates computer parts in the space normally occupied by the top drawer of a pedestal, disc drive slots being concealed by a drop-down false drawer front (14). A further false drawer front (15) in the centre of the desk conceals a keyboard (4) on a sliding shelf. Rear hinging of the continuous (uninterrupted) desk top allows easy access to the computer parts when the top is unlocked. When the computer is not in use, substantially all parts are concealable. Not only is it difficult to recognise that the desk contains computer parts, e.g. power supply, CPU and disc drives, but these are individually mounted to the wood of the desk, and not incorporated in a steel case, making removal of the computer correspondingly difficult. External connections may be by concealed hard wires, or wireless (e.g. infrared or radio). A touch sensitive pad may be incorporated immediately below the desk surface. Concealed connectors for a flat panel display (2) and mouse (1) may be provided.

Title: Co-channel interference canceler and driving method therefor
Inventor: LEE MYEONG-HWAN
IPC: H04N5/21
Filed: 1998-04-20
Abstract: A co-channel interference canceler and a method therefor. The co-channel interference canceler includes: a co-channel interference rejection filter for outputting a second signal by performing co-channel interference rejection filtering on a first signal including co-channel interference; a selection signal generator for generating a selection signal which selects the signal with less error by calculating the error of each of the first and second signals with respect to a reference signal; a selection corrector for outputting a corrected selection signal by correcting the selection signal such that a predetermined one of the first and second signals is selected in a predetermined error region; and a selector for selecting one of the first and second signals according to the corrected selection signal. Therefore,unlike the selection signal whose state is easily changed even when the channel condition changes only slightly, the selection signal for driving the NRF is maintained in a predetermined error region to select a predetermined path, thereby improving stability and performance of the system.

Title: An ultrasonic apparatus and method for increasing the flow rate of a liquid through an orifice
Inventor: JAMESON LEE KIRBY
IPC: B29C48/475
Filed: 1996-12-04
Abstract: An ultrasonic apparatus and method for increasing the flow rate of a pressurized liquid through an orifice by applying ultrasonic energy to a portion of the pressurized liquid. The apparatus (100) includes a die housing (102) which defines a chamber (104) adapted to receive a pressurized liquid and a means for applying ultrasonic energy (116) to a portion of the pressurized liquid. The die housing (102) further includes an inlet (110) adapted to supply the chamber with the pressurized liquid, and an exit orifice (112) defined by the walls of a die tip (136). The exit orifice (112) is adapted to receive the pressurized liquid from the chamber (104) and pass the liquid out of the die housing (102). When the means for applying ultrasonic energy (116) is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip (136). The method involves supplying a pressurized liquid to the foregoing apparatus (100), applying ultrasonic energy to the pressurized liquid but not the die tip (136) while the exit orifice (112) receives pressurized liquid from the chamber (104), and passing the pressurized liquid out of the exit orifice (112) in the die tip (136).
