Cable lacing tie devices and methods of using the same are disclosed. The cable lacing tie devices include a head assembly and a cable lacing tape. The head assembly being configured to retain a first portion of the cable lacing tape within the head assembly and having a length of the cable lacing tape extending from the head assembly. The head assembly further adapted to retain a second portion of the cable lacing tape extending from the head assembly. The methods of using the cable lacing tie devices to hold together a plurality of objects with a cable lacing tie device include retaining a first portion of a cable lacing tape in a head assembly, looping the cable lacing tape around the plurality of objects and retaining a second portion of the cable lacing tape within the head assembly.

A system includes a knot tying device for tying a filament in a knot around an article and a filament delivery device from which is drawn the filament. The filament delivery device may be in the form of a cartridge having a housing sized and arranged to be releasably attached to the knot tying device where the housing has an opening through which pre-cut or loosely coupled lengths of the filament can be drawn. The knot tying device includes a shuttle attachable to the filament where the shuttle is caused to be moved during a knot tying process around an article to be tied and a device for at least pulling the filament away from the article at appropriate times during the knot tying process.

A fluid handling device includes a body portion defining a flow passage and an impulse chamber extending from the flow passage. The impulse chamber is fluidly coupled with the flow passage and has a pair of opposing ends defining a length dimension therebetween. The impulse chamber further presents a diameter dimension transverse to the length dimension, wherein the length dimension is at least 3 times and not greater than 10 times the diameter dimension. The device further includes at least one sensor operably coupled with the body portion. The sensor is disposed proximate the end of the impulse chamber opposite the flow passage and presents a sensing face facing into the impulse chamber.

The present invention relates to a device with an ultrasonic-based probe for drilling and coring. The invention uses ultrasonic and subsonic vibrations produced by a frequency compensation coupler or free mass to produce the hammering action of a partially disengaged probe, with a relatively low axial force required. The invention can also be fitted with irrigation and aspiration capabilities. The invention can furthermore be furnished with a body sensor-feedback apparatus, which provides feedback to the operator as to the optimal frequency and power use of the generator. One embodiment of the invention also has a cooling mechanism to keep the drill or coring apparatus at an optimum temperature.

A system and apparatus are disclosed for improving safety and hydro-flow thrust from a hydro-drive device. The apparatus may include a shroud having a first opening for the ingress of water, and a second opening for the egress of water, a diverter connected with the shroud and angled in a direction selected to direct water to form a vortex as the water exits the shroud, and a screen connected with the second opening and configured to allow a substantially free flow of water and to prevent marine, plant, animal, and human life from contacting the hydro-drive device. The system may include a motor, a hydro-drive device coupled to the motor, and the apparatus.
摘要:
A percutaneous surgical instrument for de-bulking calculi or drilling bone includes an actuator for generating vibrations at ultrasonic frequencies and a horn coupled to said actuator for amplifying the actuator vibration. A fixed probe is attached to said horn for engaging the calculi and introducing the ultrasonic frequencies thereto. A floating probe is disposed concentric to and under said fixed probe and slidable thereover. A free mass is disposed between the horn and the floating probe for oscillating therebetween, in response to actuator vibration, for causing low frequency impact with the calculi.

A quiet motorized roller shade assembly has a roller tube for reeling and unreeling a reelable shade and an internal electric motor. The motor turns a drive wheel that mates with a the interior of the roller tube so that the roller tube rotates in response to the rotation of the drive wheel. The electric motor disposed within a motor sleeve for reducing sound transmission within the roller tube. A crown is disposed on one end of the roller tube. The drive wheel and the crown maintain a space between the electric motor and the roller tube so that the motor does not directly contact the roller tube. An idler assembly is disposed proximate the end of the roller tube opposite the crown. The idler assembly includes a spring member for reducing vibration between roller shade assembly and the mounting bracket during operation of the electric motor.
