Patent CA-2304699-A1 (CA)
Title: Visual display
Inventor: POTHOVEN FLOYD
IPC: H01J9/24
Filed: 1998-10-01
Abstract: The apparatus for sealing face plates (753) and cathodes (754) has three stations (701, 702, 703). The first (701) is a preheater, the second (702) is an alignment and irradiation station and the third (703) is a controlled cooling station. Beneath each station, a vacuum pump (710) capable of drawing ultra-low pressures is provided. The preheater is equipped with upper and lower banks of radiant heaters and reflectors (712). The upper heaters are provided above a quartz window (713) of a chamber (714) constituting the station. The pressure in the preheater is pumped down to that in the alignment and irradiation station prior to opening of the gate valve between them and transfer of the face plate and cathode. At the alignment and irradiation station, further heaters (716) are provided. Those above the face plate and cathode, the face plate being uppermost, are mounted on frames (717) about hinges (718), whereby they can be swung up to clear this station's top quartz window, exposing the face plate to the view of an optical system (719) and a laser (720). Manipulation controls (722) are provided for manipulating the position of the face plate to be in pixel alignment, as measured by the optical system (719), with the cathode. The laser is traversed around frit between the face plate and the emission device to cause the frit to melt into contact with both and freeze off once the laser has traversed further. The cooling station (703) has meanwhile been pumped down and the sealed device is transferred to it. The temperature of the device is allowed to rise very slowly, in order to reduce the risk of thermal cracking to as great an extent as possible. As the temperature slowly falls, air is slowly introduced, so that the finished device can be removed to the ambient surroundings.

Title: Two-piece hub extension
Inventor: RADKE GREGORY DEAN
IPC: B60B3/16
Filed: 2000-08-15
Abstract: A two-piece hub extension for adding dual wheels to a mechanical front-wheel drive axle of an agricultural tractor has an inner extension ring that surrounds the final drive cover of the front axle and an outer extension member of reduced diameter that extends outward from the inner extension ring. The inner extension ring only extends outward far enough to clear the axle final drive cover. The inner ring is mounted by bolts that extend entirely through ring so that the bolt heads are external of the inner ring and can be easily reached. The outer extension member is mounted to the inner extension ring by long bolts extending through the inner extension ring and into the hub. The dual wheel is mounted to the outer wheel hub.    The reduced diameter of the outer extension member results in improved crop clearance between the two tires.
