Abstract: TITLE:  INJECTION CONTROL DEVICE         FOR SUBTERRANEAN WELL CONDUIT                    ABSTRACT OF THE INVENTION         A downhole injection valve for selectively opening and closing the bore of a tubing string to permit the passage of chemical treatment fluid to a downhole tool comprises a first annular valve element mounted in a valve housing which is connected in a tubing string above the downhole tool.  A slip joint is connected between the valve housing and the downhole tool to permit relative upward and downward movement of the valve housing with respect to the tool.  A second annular valve element is disposed in surrounding relationship to a support rod which is inserted in the tubing string and supported at its bottom end by the downhole tool.  Upward movement of the tubing string will then effect contact of the first annular valve element carried by the valve housing with the second annular valve element carried by the support rod, and thus move such elements into engagement and close all fluid flow through the bore of the tubing string.  Conversely, downward movement of the tubing string will effect axial separation of the valve element carried by the support post.  The support post may be removed by a fishing neck assemblage having a lost motion connection with the support post.  The lost motion connection permits the operation of a bypass valve to equalize fluid pressure across the support post so that it may be conveniently removed by wireline.

Abstract: ABSTRACT OF THE DISCLOSURE    A  vital inserter driver includes can oscillator which, upon energization, outputs a signal of predetermined frequency to two identical parallel-arranged counter circuits, which step down the oscillator output to the desired frequency.  One counter output is fed to an inverting amplifier, while the other is coupled to a noninverting amplifier, thereby resulting in output count signals of identical frequency and amplitude but being 180° out of phase.  A summing circuit, having two series-resistance arrangements with different resistance values for weighting purposes, and a summing transformer passes a signal of a predetermined magnitude through an overload protection device which could be a fuse or a breaker, when the output count signals are 180° out of phase.  When the count signals are other than 180° out of phase, a failure in circuitry or operation has likely occurred, and the signal output from the summing circuit exceeds the predetermined magnitude and activates the overload protection device.

Abstract: Abstract A method for evaluating the in vivo ability of a contact lens to become or remain wet includes the steps of supporting the subject's head to determine a fixed orientation of the lens, illuminating the lens with coherent light, imaging the pre-lens tear film in a manner to form an interference pattern, recording in a time sequence manner the image formed thereby, and determining the tear film thickness by correlating the interference bands of the recorded image.  The classical contact angle is derived, and other measures, such as the time interval from blink until the onset of tear film breakup, or the time until the film evaporates, and the initial or average film thickness are derived. In addition, the nature and evolution of localized dry spots may be directly observed, clarifying the causes of tear film breakdown on worn contact lenses.  The invention includes methods for the evaluation of wetting characteristics as they are affected by lens material, lens aging and lens soiling, as well as the evaluation of solvents, additives and cleaners, for their effects on wetting characteristics.         Apparatus for performing the method include a means for supporting the head so as to determine a fixed location of the contact lens, a coherent light source, and a camera focused at the pre-lens film from a position to image light from the source specularly reflected from the front and rear surfaces of the tear film.  A film motion analyzer provides numerical coordinates of interference bands, and a microprocessor analyses the coordinates to provide a quantitative measure of lens position or wetting characteristics.

Abstract: A method of processing oxide materials by means of a laser beam with a photon energy being less than the band gap of the material. Initially, it might be expected that no absorption would take place. However, experience has shown that the different energy levels in the band gap may be utilized. These energy levels are apparently caused by several types of structural defects and imperfections, each resulting in different energy levels in the band gap and some thereof enable an absorption of photons, the energy of which being less than the band gap energy. This causes the crystal to be heated, which successively may lead to the band gap being less than the photon energy. Subsequent hereto, the photons are absorbed without any difficulties, and an ablation or an etching process may then be initiated in a controllable manner. <IMAGE>

Abstract: A linear motor comprises an armature and a stator each adapted to provide a sequence of North and South poles along the length of the motor. The pole pitch of the stator magnets is different from that of the armature coils such that with appropriate energization of the coils this difference in pole pitch and stator can result in a net thrust of the armature relative to the stator in a desired direction at any location within a range of relative longitudinal positions of the armature and stator. The motor may be subject to closed loop velocity-and/or positional control and means are disclosed to achieve this. Several variations in pole configurations and means of controlling the coil energization are disclosed.

Abstract: It has long been known that a taking of core samples from unclean grain materials by means of a simple stick-in spike does not produce any representative results, and a substantial improvement is already achieved by configuring the spike 2 with an interior suction tube 26 and an outer blowing tube 20, which tubes at the tip of the spike are open to each other via a ring gap 28 so that the material taken in through the tip of the spike is transported away by the suction air to a material separator 12 without there being any corresponding "dust suction effect" outside the mouth of the spike, resulting in uncertainties. In the invention, a very small hole 34 is formed in the outer wall of the pipeline 14 between the pressure side of the blower and the spike, through which a slight air flow will be blown out, so that a corresponding slight intake of air will occur through the open end of the spike, and it has been shown that this will achieve a substantial improvement in the accuracy of the sampling. <IMAGE>
