Title: Deflection system with a controlled beam spot
Inventor: GROTE MICHAEL DENTON
IPC: H04N9/285
Filed: 1991-07-19
Granted: 2001-01-30
Abstract: A deflection apparatus comprising a cathode ray tube produces a field gradient that reduces a tendency of a major axis of a beam spot to become elongated at each corner, at each end of a horizontal axis and at each end of a vertical axis of a display screen (22) relative to the beam spot at the center of the display screen. A beam spot stigmator (24) causes the beam spot to be substantially anastigmatic at each of the corners, the end of the horizontal axis and the end of the vertical axis of the display screen. In an embodiment of the invention, means (11) are provided for producing a first non-uniform field providing a lensing action containing a time varying field portion not produced by the deflection coils (10, 99), said means (11) comprising a quadrupole doublet.

Patent CA-2117561-C (CA)
Inventor: SCHWINGHAMMER PATRICK ALLEN
IPC: H04W88/02
Filed: 1993-12-29
Granted: 1998-04-28
Abstract: A nondirectional antenna assembly, and associated method, for a radio operative at high frequencies, such as at frequencies of approximately 1.8 Gigahertz. A first antenna portion, formed of a one-half wavelength, helical winding is supported at a distal side of a nonconductive whip. A second antenna portion, comprised of a helical winding supported at a proximal side of the nonconductive whip, and a one-quarter wave helical winding, connected to radio circuitry of the radio transceiver, couples the first antenna portion to the radio circuitry. Because the first antenna portion is positioned at a distal side of the nonconductive whip, shadowing occurring as a result of positioning the radio transceiver proximate to a user during operation thereof is less likely to interfere with operation of the radio transceiver.

Abstract: A roller dispenser includes a pair of counter-rotating cylindrical grid die rolls disposed adjacent a bottom opening in a hopper containing material to be dispensed. The grid die rolls have openings therein which assist in separating the material within the hopper prior to depositing the material on receiving articles or products passing therebeneath. Within the grid die rolls are shields or deflector plates which prevent the material entering the grid die rolls through openings in the upper surface of the grid die rolls from completely filling up the interior of the grid die rolls. Pin rolls within the grid die rolls push the material beneath the shields or deflector plates out through openings in the lower surface of the grid die rolls, making the grid die rolls self cleaning. An agitating bar assembly within the hopper keeps the head pressure or weight of the mass of the material within the hopper from forcing the material between the grid die rolls and allowing the grid die rolls to separate the material at a controlled rate.
