摘要:
A drill pipe mountable wellbore cleaning tool apparatus is of an improved configuration that enables attachment to a drill pipe joint having first and second connector end portions and a cylindrically shaped portion in between the connector end portions. The drill pipe joint with attached debris cleaning tool or tools is made part of a drill string. The apparatus includes a support sleeve that is mounted to the drill pipe joint in between the connector end portions. The support sleeve abuts but does not invade the integrity of the cylindrical portion. Centralizers are attached to the opposing ends of the support sleeve, with each centralizer overlapping a portion of the support sleeve. The support sleeve carries one or more debris cleaning tools in between the centralizers. These tools enable debris to be removed from a wellbore. At least one locking clamp is attached to the cylindrical portion next to a said centralizer. The locking clamp prevents the support sleeve from moving longitudinally along the drill pipe joint.

A tool for suspending in a well retrieves various metal debris from the well, and includes an elongated tool body with a plurality of magnets included in a plurality longitudinal ridges which are circumferentially spaced. In the method a plurality of magnets can be positioned within openings, recesses, or pockets in each ridge, and held in place by one or more retaining plates, the tool being connected to a drill string and lowered into a well.

A method and apparatus for simulating the characteristics of an analog tone control circuit using digital computation means. The desired analog tone control circuit is modeled using initial treble, middle, and bass settings, following which simulation software is used to generate the model's magnitude and phase responses versus frequency, extending over the desired frequency range. Gains, zeroes and poles are then chosen to produce magnitude and phase versus frequency response matching as closely as possible to that of the simulated circuit. A bilinear transformation is then performed to produce a digital filter prototype. Update equations responsive to treble, middle, and bass settings of the simulated tone control circuit are then designed in a specified form, providing for modification of the digital filter parameters as a function of updates in the treble, middle, and bass settings of the simulated tone control circuit.

A tent assembly defining a tent portion for attachment to the bed of a pickup truck is disclosed. The tent topper has a plurality of openings therein at pre-selected locations which permit the tent to engage a plurality of adjustable pins. These pins, with their associated adjustment knobs, provide a means for stretching or making taut the tent to make the tent topper. Also, the tent portion is attached and fixed to a V-shaped roof support. Furthermore, the tent topper may be easily removed from the truck, disassembled, and stored in, for example, a suitcase type container in the truck cab behind the seat, as many truck owners do not like to permanently affix camper type shells on their truck beds.
