摘要： An optimization technique is provided that optimizes data access by mapping each table, or row and/or column in a table, to a particular query, depending on whether the data in said table, row or column is ‘hot’ or ‘cold’ data. In one aspect, the invention features a method for optimizing the access time of an SQL query to a database including data. The method includes receiving, for each query type, a data frequency access measure and associating each query type with a processing rule set, according to the received data frequency access measure.

摘要： A mulching mower mechanism, having an inverted U-shaped channel member positioned within the outer periphery of a cutting chamber of a mower deck for generally confining the clippings circulating at the outer periphery of the cutting chamber. The channel member extends generally across the mower deck's discharge outlet for generally diverting the stream of clippings away from the outlet and thereby serves to maintain the clippings within the deck to be re-cut by the blade. The channel member includes an upper and outer wall portions positioned adjacent the discharge outlet for generally blocking the clippings and air within the channel from exiting the discharge outlet. The channel member also includes an inner wall portion which separates the stream of clippings from the relatively clean air circulating within the inner portion of the deck. The discharge outlet is in fluid communication with the inner portion of the cutting chamber for allowing the clean air to exit the cutting chamber via the discharge outlet, thereby maintaining an updraft within the cutting chamber.

摘要： A closed granular chemical handling system comprising a dispensing valve and a receiving valve. The dispensing valve and the receiving valve are automatically opened when the valves are coupled together, and are automatically closed when the valves are uncoupled from one another. The valves are configured so that the receiving valve always is the first to open and the last to close. The valves are driven together by a camming structure having a neutral portion that acts as a delay between the opening and closing of both values so as to allow granular material to flow from between the valves through the receiving valve.

摘要： A spider wheel for a rotary incorporator for one pass incorporation of chemicals or small grains in previously tilled soil. The incorporator includes two rows of aggressive, large diameter spider wheels supported from a toolbar for rotation in the soil about axes offset at an acute angle to the transverse direction. The spider wheels are to provide good incorporation and a smooth seed bed without hilling or chemical banding. A smaller diameter, depth limited spider wheel on each outermost end of the implement feathers the effect of the angled wheels. The spider wheels include tines having soil working surfaces for good mixing and soil moving action and a large gullet area for good trash shedding and throwing characteristics. The tines on the spider wheels adapted for use in firmer soils, for example, the forwardmost wheels on the incorporator, have end portions which are oriented to reduce scrubbing of the soil for easier entry and reduced vertical force requirements while the inner portions of the tines help to limit depth of penetration of the wheels.
