Title: Bactericidal vacuum cleaner filter bag
Inventor: URSO JOSEPH P
IPC: B01D46/02
Filed: 1999-10-26
Abstract: A vacuum cleaner filter bag exposes bacteria in incoming dirty air to bactericide throughout the useful life of the bag. Fingers provided on the interior walls of the bag are impregnated with bactericide. Air flow in the bag during vacuum cleaner operation causes the fingers to stand out from the wall, intercepting particles in the dirty airstream and exposing bacteria on those particles to the bactericide. The fingers stand out from the wall, and thus kill bacteria, substantially throughout the useful life of the bag, even after a cake of dust and dirt has formed on the inner walls of the bag.

Title: Drag-type rotary drill bit
Inventor: CARAWAY DOUGLAS
IPC: E21B10/42
Filed: 1999-12-03
Abstract: There is provided a rotary drag-type drill bit comprising a bit body having a leading surface comprising a plurality of pads, at least some of the pads each having a wearable abrasive surface including particles of superhard material and defining an outer profile of the pad, at least a part of the outer profile of at least one of the pads being disposed inwardly or outwardly of the outer profile of the other pads. With this arrangement, during initial drilling through softer formation, most of the removal of formation will be effected by the outermost of the abrasive pads and little or no formation will be removed by the more inward pads. Accordingly, the bit will act as a lighter set bit and good rates of penetration may be achieved. As drilling proceeds and the bit wears, which may occur more rapidly as the bit meets harder formations, the more outwardly disposed pads will wear down more than the inwardly disposed pads so that the inwardly disposed pads will begin to contribute more to the cutting action of the bit, so that the bit effectively becomes heavier set. As drilling progresses to a point where all of the pads wear down to the same level, the bit will then act as a conventional heavy set bit where all the abrasive surfaces lie on the same profile.

Patent CA-2312622-A1 (CA)
Inventor: FERGUSON LARRY PATRICK
IPC: A01B13/02
Filed: 2000-06-26
Abstract: An opener assembly includes a single opener disk rotatably supported from a drawbar and angled approximately five degrees from the forward direction to define a shadow area behind the trailing surface of the disk. A material placement boot and delivery tube are supported adjacent the trailing surface substantially entirely within the shadow of the disk and have profiles conforming to the furrow profile. The boot and the outlet portion of the tube also lie within the periphery of the disk for protection. The tube has an upper portion with a round cross section which changes to an elliptical cross section towards the outlet to remain within the shadow while retaining high throughput capabilities. First and second wheels are supported on opposite sides of the disk to urge soil downwardly behind the outlet of the delivery tube immediately after the material is deposited.  The immediate soil action caused by the closely spaced wheels pushes the material to the furrow bottom and prevents material bounce for more constant material depth. A short, lightweight wheel arm on the trailing side of the opener disk reduces assembly length and weight, and wheel bias towards the soil is primarily by spring action rather than weight for fast response to ground contours. The wheel on the leading side of the angled opener disk is supported behind the disk axis by an arm assembly which provides depth adjustment from the forward end of the drawbar. The wheels and the disk are angled generally in the same direction for handling trash.
