An adjustable clothes hanger includes a shaft and a plurality of arms slidably positionable therealong. Such a plurality of arms include core sections provided with grooves for receiving the shaft therethrough, respectively. The grooves extend along a length of the arms, thereby making the arms movable between retracted and extended positions for adjusting a length of the hanger. Advantageously, each core section is provided with a closed end portion laterally spaced from the center of the hander for defining a maximum distance along which the plurality of arms can be transferred. The hanger further includes a hook for engaging a support surface so that the hanger can conveniently be maintained at a stable position during operating conditions.

The filter segments of each part group adjoin each other in a lengthwise axial manner. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

The invention provides a method for measuring internal force of a guy cable in active service, which comprises the following steps: selecting two points on a guy cable to be measured, and fixing the two points so that a cable section to be measured between the two points is formed into a string pattern; selecting a point on the cable section to be measured between the two points, jacking a height at the point, and measuring the height and the jacking force required for jacking the height; and according to the height, the jacking force and the distance between the two points, using the stress rigidization effect of the guy cable and a principle of statical equilibrium to evaluate the internal force of cable section to be measured. The method has the advantages of convenient measurement, high precision and low measuring cost. The invention also provides a measuring device using the method.

An electromagnetic borehole telemetry system for transmitting information between a borehole transceiver and a surface transceiver located at or near the surface of the earth. Tubulars, such as steel casing and liners, are typically set within the well borehole to stabilize the wall of the borehole and to assist in hydraulically isolating penetrated formations. The invention utilizes these tubulars cooperating with one or more signal wires to reduce attenuation and noise in signals transmitted between the borehole and surface transceivers. The one or more signal wires are typically disposed within an annulus formed by the borehole wall and the outside surface of the casing. The one or more signal wires are connected at one end to one or more connection terminals positioned preferably near the bottom a tubular string. Opposing ends of the one or more signal wires are connected to one or more terminals of the surface transceiver. By minimizing signal attenuation and noise, the telemetry system can be effectively used at greater depths in the borehole. The telemetry system can be embodied in a measurement-while-drilling system, a formation testing system, a production monitoring system and other system requiring communication between a downhole assembly and the surface of the earth.
