Abstract: A bias current servo loop for a magneto-resistive recording head detects distortion in the read signal from the MR head, and adjusts the operating point for the head to minimize the distortion. The distortion is detected by monitoring the second harmonic of a digitized sample of the read signal. A running average of the digitized amplitude of the second harmonic is generated by a digital bandpass filter. The root mean square of the running average of the digitized amplitude of the second harmonic is estimated. The estimated RMS value is compared against a reference value indicative of minimum distortion and the difference between the estimated RMS value and the reference value is used to adjust the bias current.

Abstract: Apparatus for stabilizing a test specimen in a compression/tension testing machine. The apparatus supports the test piece along its lengthwise edge or edges to prevent unwanted Euler buckling, however in a manner so as not to prevent sublaminate buckling.

Abstract: Apparatus and method are described for controlling thickness of plastic films produced by the blown film process. The apparatus is an air cooling ring modified to include devices for locally modifying the temperature of the air discharged from the air ring onto the blown bubble. Local variations in the temperature of the cooling air applied to the surface of the bubble result in variations in the bubble cooling rate and viscosity, with consequent variations in thinning during transverse bubble expansion. The method includes controlling the location and extent of local temperature variation applied to the bubble in response to comparison of measured film thickness with a desired film thickness.

Abstract: Color change devices which are capable of undergoing a color change on bending. The devices comprise a flexible substrate having a color generating metal (e.g. a valve metal such as Ta or Nb) at at least one surface and an intimately contacting optically thin anodic film covering the color generating metal and generating a visible color by light interference and absorption effects. The thin anodic film is produced by anodizing the color generating metal in the presence of an adhesion-reducing agent (e.g. a fluoride) for weakening the normally tenacious bond between the anodic film and the metal. Devices of this kind capable of being activated by bending, as well as by separation of the constituent layers, are produced by carrying out the anodization step in the presence of a particular concentration of the adhesion reducing agent from a narrow range (e.g. 40-350 ppm of fluoride).

Abstract: Disclosed is a process for improved removal of contaminants including oily wastes and other organic hydrocarbonaceous materials from ground waters and areas adjacent to or in the vicinity of ground water locations. Ground and ground water contamination due to its unique nature, as being below ground and often not readily removable, has presented unique challenges to efforts seeking to render contaminated sites safe for habitation and/or contain and prevent contaminants to other, non-contaminated areas. The present process presents a viable solution to the problem of removing hydrocarbonaceous contaminating materials from ground and ground water. The process includes the use of at least two injection wells and at least one extraction well. One of the injection wells is being used for introduction of steam into a subsurface saturated zone.

Abstract: Curable polycycloolefin resin solutions having particular utility in the fabrication of printed circuit boards are disclosed. A solvent soluble polymer is typically solution polymerized from norbornene-type monomers in the presence of a metathesis catalyst package. This polymer may then be purified by precipitation and redissolution. A curing agent, such as a high activation temperature peroxide can then be added to the solution and then this curing agent containing solution can be used to impregnate a suitable substrate such as a fiberglass cloth. The impregnated substrate can then be dried, preferably at temperatures above the glass transition temperature of the polycycloolefin but below the activation temperature of the curing agent. Then one or more prepregs can be stacked and laminated to conductive foil at a temperature high enough to activate the curing agent.

Abstract: A camshaft in an internal combustion engine encounters various torques during operation which produce torsional vibrations leading to excessive noise and reduced gear life. An active inertia absorbing system includes a camshaft gear integrally formed with a carrier. The carrier has a plurality of bores having a predetermined diameter. A plurality of weights are positioned within the bores and have a predetermined diameter less than the predetermined diameter of the bores so that the weights are free to move within the bores. The mass of the carrier and the weights establish an inertia which acts in opposition to the torques applied to the camshaft for absorbing the torsional vibrations of a camshaft.
