摘要:
A telescopic leaf blower extension apparatus for extending a leaf blower hose includes a proximal tube that is configured to attach to a flex tube of a leaf blower. A distal tube is coupled to the proximal tube. The distal tube is telescopably coupled to the proximal tube. The distal tube has a retracted position within the proximal tube and an alternate extended position. A clamp means is coupled to the proximal tube and is selectively engageable with the distal tube to prevent the distal tube from moving between the retracted position and the alternate extended position.

A bearing assembly is provided having a roller bearing with an inner race fitted around the journal portion of an axle. An outer raceway combines with the inner raceway to receive roller elements. A backing ring is centered to the shaft fillet. Tapered roller elements are located between and contact the inner and outer raceways. A cage is comprised of an inner ring, and outer ring, and a plurality of pocket bars and support pocket bars extending between the inner and outer rings. The support pocket bars have an overall greater thickness than the pocket bars. The cage is a generally unitary structure comprised of a nylon resin material with a fiber fill.

A hurdle obstacle utilized curved bars of selected sizes each supported in the apex of a standard module conical base such that a main portion of the bar extends parallel to the ground for jumping over or moving beneath. One end of the obstacle bar is swivelably engaged in the base by means of a flanged bushing which receives one end of the bar so that upon impact with a user, the safety obstacle device swivels out of the user's path to prevent tripping or other injury.

A circuit synchronizes the actuation of multi-dimensional separating valves with a system clock also coupled to a data acquisition circuit such that signals from a detector are synchronized and no signal information is lost. The system comprises an acquisition clock coupled to a data acquisition logic system and to a modulator valve control. The modulator valve control is, in turn, coupled to a multi-dimensional separation technique valve unit for controlling the valves for introduction of the eluant from a first separation column to a second, faster column in synchronism with acquisition of data by a detector.

The present invention relates to a system and method of making a verification decision within a speaker recognition system. A speech sample is gathered from a speaker over a period of time a verification score is then produce for said sample over the period. Once the verification score is determined a confidence measure is produced based on frame score observations from said sample over the period and a confidence measure calculated based on the standard Gaussian distribution. If the confidence measure indicates with a set level of confidence that the verification score is below the verification threshold the speaker is rejected and gathering process terminated.

A novel assembly for a railcar axle bearing is presented. The assembly includes a backing ring affixed to the fillet of the journal of an axle and a locking ring for further affixing the backing ring the journal. The locking ring has an inboard end affixed to the dust guard of the axle and an outboard end for engaging the backing ring.

A bearing assembly is provided having a roller bearing with an inner raceway fitted around the journal portion of an axle. An outer raceway combines with the inner raceway to receive roller elements. An improved lubricant seal arrangement is provided between the wear ring and the supporting outer raceway comprising a stator element, a rotor element and a flinger element.
