Title: Combined magnetic channel signal sensor and servo control track following system and method
Inventor: VINAL ALBERT W
IPC: G11B5/02
Filed: 1985-05-16
Granted: 1992-02-04
Abstract: COMBINED MAGNETIC CHANNEL SIGNAL SENSOR AND SERVO CONTROL TRACK FOLLOWING SYSTEM AND METHOD        Abstract Servoing is accomplished utilizing the same read head and the same data track by utilizing a differentially sensitive magnetic sensor.  The sensor is utilized as the data read back head sensitive element but separate outputs from the differential sensor are supplied to separate track following amplifiers isolated from the data signal amplifier.  The separate amplifiers for the servo information utilize the inherent differential sensitivity of the sensor.  As one-half or the other of the differentially sensitive sensor drifts over the edge of a recorded data track, its signal output level will follow.  This differential between the left and right halves of the sensor in the form of a change in signal level at the output can be amplified, referenced to common ground for high common mode noise rejection, and a differential signal derived from the difference between the left and right halves of the sensor.        The differential is proportional to the distance off track that the sensor has wandered provided that at least a portion of the sensor remains over the track.  A servoing system utilizing the differential output between the left and right and driven by the magnitude of the difference between left and right half signal components is utilized to force the head positioning system back in the appropriate direction to center the head over the data channel.

Granted: 1991-06-04
Abstract: ABSTRACT           A blowout controller is adapted to sit between the well casing and the production assembly of a hydrocarbon well, the controller being mountable over the upper end of the casing.  The controller has a first aperture, through which the drill pipe is adapted to extend, and also has a second aperture.  At the first aperture, the controller has a first sealing means capable of closing around a drill pipe to seal flow through the first aperture except flow within the drill pipe.  The controller has a second sealing means in the first aperture which, if necessary, is capable of crushing the pipe and preventing all flow through the first aperture.  Simultaneous with such partial or full closing of the first aperture, the second aperture is opened; the second aperture is connected to a regulated flow conduit which reduces the flow of the hydrocarbon through the controller at a sufficiently low rate that damage to underground formations is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE A method of producing self-supporting ceramic composite bodies of desired shaped by infiltrating a permeable preform with polycrystalline matrix material consisting essentially of an oxidation reaction product obtained by oxidation of a parent metal precursor, such as aluminum, and optionally containing therein metallic constituents.  The composite body is formed by contacting a zone of a permeable preform, having at least one defined surface boundary spaced from said contacting zone, with a body of molten metal which is reacted with a suitable vapor-phase oxidant to form an oxidation reaction product.  Within a certain temperature region, and optionally with one or more dopants in or on the parent metal or said permeable preform, molten parent metal migrates through previously formed oxidation reaction product into contact with the oxidant, causing the oxidation reaction product to grow into the preform toward said defined surface boundary so as to infiltrate the preform up to said defined surface boundary, and provide the composite structure of desired geometry.
