Patent CA-2319434-A1 (CA)
Inventor: POLLUTRO DENNIS C
IPC: B41J2/385
Filed: 1999-12-20
Abstract: An electron beam printer assembly for operating a standard electron beam print cartridge (such as an eighteen inch 600 DPI print cartridge) includes an RF generator which has a powdered iron core transformer, and a dual pulse width generator operatively connected to the transformer. The RF generator also includes a power driver, control logic, and an oscillator feedback circuit. The dual pulse width generator may comprise a NOR gate, a capacitor, two resistors, and a diode, all connected to an adjustable voltage source. The transformer core may be toroid-shaped, and of carbonyl SF. Using this RF generator it is possible to image a substrate moving at a speed of greater than 200 FPM, and to operate at a frequency of about 5 MHz in an efficient manner, to eliminate print gradients due to an overdriven transformer, to eliminate transformer temperature failures due to core loss, and to provide greater flexibility in transformer construction and design, and less power loss in the transformer drive transistor.

Title: Clamp for an external bone fixation device
Inventor: HEHLI MARKUS
IPC: A61B17/64
Filed: 1998-05-07
Abstract: A clamp for an external fixation device, includes a basic body fitted with a first, continuous borehole for receiving a longitudinal support and a second, continuous borehole disposed perpendicular to the first borehole and partly intersecting it for receiving a tension bolt. The tension bolt includes a transverse borehole for receiving a bone fixation device, such as a bone pin, and further includes threading at one free end for engagement with a nut that forms a stop against the basic body. Tightening of the nut on the tension bolt permits the bone fixation device to be held against the basic body. An additional, threaded borehole is provided in the basic body, terminates in the second borehole, and receives a fixation screw. The diameter of the tension bolt can be less than the diameter of the second borehole and the fixation screw can be used to position the tension bolt so that it lies across a portion of the first borehole and bears tangentially against the longitudinal support.

Patent CA-2332163-A1 (CA)
Inventor: KUHL RONALD R
IPC: A01K97/05
Filed: 2001-01-25
Abstract: A bait container has a housing, a top and bottom which at least partially surround the bait. A nozzle having a funnel portion and a bait-dispensing exit end extends from the top. A flow-inducement chamber permits a flow stream to be created which carries the bait into the bait-restraining exit end of the nozzle when the container is tipped. The fluid will drain through primary flow passages into the flow-inducement chamber and out of the chamber back into the housing through a secondary flow passage. A strap on the bait container permits the container to be suspended from a shoulder or waist of the fisherman. A stopper keeps the bait in the bait-dispensing portion until the fisherman is ready to dispense the bait into her/his hand. An insert for the exit end of the nozzle can permit different size bait to be dispensed one at a time. The bait container of the present invention permits the fisherman to dispense a single bait to be dispensed with a minimum loss of water, or wetting of his/her hand, and without the removal of the container's top.
