Between the drive sleeve and the ball screw there is a control arrangement, c...

The infusion of fluid from the formation being drilled into a borehole (30) is detected by modulating the drilling fluid stream in the drill pipe and detecting pressure variations commensurate with the modulation at the surface in the annulus (28) between the drill pipe (12) and wall of the well. The detected pressure variations are compared in phase and/or amplitude with their own near term past ...

In a brake actuator device, wear of brake lining, which results in the increase of stroke of the brake actuator device consisting of piston and cylinder, is compensated by an adjuster which functions automatically when the brake is operated. The adjusting process takes place continuously and preferably at the onset of the actuation of the brake. A slip clutch turns the adjuster member which is con...

PURPOSE: To lengthen the working service life by separating a part of an inflow fluid containing no drilling object as a working medium of a hydraulic system, and preventing a polluted drill fluid from flowing in a housing. CONSTITUTION: A rotor of a generator 23 rotates together with a drill shaft 2 to generate electric energy. A pressure pulse generator 25 is driven by a clean drill rod fluid, a...

A resonant tag circuit having at least one resonant frequency is operative in an electronic security system in which the tag circuit is sensed and electronically deactivated to destroy the resonant characteristics of the tag circuit at the detection frequency. The tag circuit is electronically deactivated by a breakdown mechanism operative within the resonant structure of the tag to cause vaporiza...

PURPOSE:To well perform the cleaning of a pipe by mixing a polishing agent consisting of washing water and crushed stone with the air stream advancing through the pipe from one end thereof while performing revolving motion to allow said air stream to pass. CONSTITUTION:A cylindrical body 15 is connected to one end of a pipe 90 at first and a dust collector receiving a polishing material 93 or a re...

The present invention relates to cooling oils which are free of salt, alcohol, halohydrocarbons and halocarbons and have a low viscosity at low temperatures and which consist of mixtures of hexamethyldisiloxane and/or octamethyltrisiloxane and/or linear decamethyltetrasiloxane and/or octamethylcyclotetrasiloxane and/or decamethylcyclopentasiloxane.
