Patent number: 5368751Abstract: The present invention pertains to a filter press which includes a plurality of filter units arranged in tandem. Each unit has a filter plate and filter elements in the form of sheets at either side. Adjacent filter elements of adjacent units form pairs of elements. A working fluid containing liquid and solid components to be separated is charged at positions in between pairs of elements. The liquid filters through the elements into the plates to be exhausted. The solids build up in cakes intermediate the elements of the respective pairs. Each pair of elements is resiliently suspended from an eccentric rotor or shaft. When the cakes are to be dislodged, the press is opened, the units being parted. Rotation of the shaft cyclically slackens the filter elements and snaps them taut, thereby dislodging the cakes.Type: GrantFiled: September 8, 1992Date of Patent: November 29, 1994Assignee: Baker Hughes IncorporatedInventor: Peter H. Glendinning

Patent number: 5038873Abstract: The present invention comprises a drilling tool including a retractable pilot drilling unit driven by a fluid operated motor, the motor comprising a stator mounted on the interior of a tubular outer housing and a rotor mounted on the exterior of a tubular inner housing axially supported in said outer housing and rotationally free with respect thereto. The pilot drilling unit is rotationally fixed within the inner housing, but axially moveable therewithin so that pressure of drilling fluid used to drive the motor will also act on reaction surfaces of the pilot drilling unit to urge it axially forward. The top of the pilot drilling unit includes a fishing head for retracting the pilot drilling unit from the drilling tool, and reinserting it therein.Type: GrantFiled: April 12, 1990Date of Patent: August 13, 1991Assignee: Baker Hughes IncorporatedInventor: Rainer Jurgens

Patent number: 4995058Abstract: In a wireline data transmission system for passing data between downhole and surface locations in a wellbore, a system for transmitting data at a frequency above the relatively low roll of frequency of a wireline permits higher data rates to be transmitted over the wireline than would be possible using standard digital data formats. The present system utilizes short duration pulses which are placed on the wireline in conformity to the transition edge between voltage levels in a typical digital data format, and thus transmits the digital data over the wireline in a manner which is not adversely affected by the phase shifting which normally occurs when bi-level voltage data formats are used for data transmission over a wireline.Type: GrantFiled: February 7, 1989Date of Patent: February 19, 1991Assignee: Baker Hughes Inc.Inventors: Terry B. Byers, Vladimir Vaynshteyn

Patent number: 4979112Abstract: The flow rate of the drilling mud within a drill string is measured by measuring the doppler frequency shift in an acoustic signal propagated from a first acoustic transducer to a second acoustic transducer laterally separated from the first acoustic transducer. Each of the transducers are disposed within the principal flow of the drilling mud. The degree of doppler shift is a measure of the flow rate of the drilling mud between the two transducers. Variations in the flow rate of the drilling mud as measured by the transducers downhole are used to transmit information or commands from the well surface to a downhole microprocessor coupled to the output of the transducers.Type: GrantFiled: July 17, 1990Date of Patent: December 18, 1990Assignee: Baker Hughes IncorporatedInventor: Carl C. Ketcham

Patent number: 4969528Abstract: The present invention comprises an improved method and apparatus for taking core samples, wherein a core drilling assembly driven by a downhole fluid motor is retrievably housed within a drilling tool of larger diameter, and wherein a plurality of cores may be cut and retrieved to the surface by withdrawal of the core drilling assembly by including an extender in the core drilling assembly each time it is brought to the surface and returned to the drilling tool, and sequentially cutting another core without postdrilling the previously cored formation section. The extenders may be included either above or below the motor used to drive the core drilling assembly, and are preferably of tubular configuration with screw-threaded connectors at their ends for rapid insertion in and removal from the core drilling assembly.Type: GrantFiled: July 18, 1989Date of Patent: November 13, 1990Assignee: Baker Hughes IncorporatedInventor: Rainer Jurgens
