Abstract: Abstract of the Disclosure A spinner transducer tool includes a shaft that is circum-ferentially magnetically coded in two sets of magnetic keys.  A core is equipped with an exciter coil and two pickup coils, and is disposed adjacent the magnetic keys of the shaft.  As the shaft rotates, the keys in each set pass by the core and coil arrangement. An alternating current signal is impressed on the exciter  coil, and  generates  alternating magnetic fields through each of the pickup coils.  As the keys in one set pass by the magnetic circuit associated with one pickup coil, the flux linkage through that circuit is alternately opened and closed.  The resulting amplitude modulation of the magnetic field through the pickup coil may be detected and measured to determine rate of shaft rotation.  Measured, mutual circum-ferential displacement of the two sets of magnetic keys permits analysis of the two amplitude modulated data signals from the pickup coils  to determine both the rate and direction of rotation of the shaft.  The spinner transducer tool shaft may be an impeller shaft in a fluid flow measuring device.

Abstract: ABSTRACT           A method of treating ferromanganese alloys in a suitable reactor wherein the feed material is heated by a transferred-arc thermal plasma and is fed directly to the reactor bath.  Accordingly, the molten bath defines a reaction zone and at least a part of the molten bath define- a lower electrode surface for the arc.  In particular, ferromanganese alloy fines may be remelted to form a physically more massive form of the alloy and additionally may be refined by the addition of suitable metal oxides to yield a product wherein the content of at least silicon or carbon is lowered.

Abstract: ABSTRACT     A bumper jack or a body jack supplied with a vehicle is designed to raise the body of the vehicle high enough that a selected wheel may be changed, but the body must be raised considerably before the wheel leaves the ground. "Do-it-Yourself" mechanics and hobbyists frequently need to raise a vehicle, wheels and all. In this invention the use of bumper jacks is extended by means of an apparatus kit fitted directly to a wheel-and-inflated-tire assembly for lifting. With it, a block fifteen to twenty centimeters high may easily be placed under a wheel in one jacking operation. This-invention offers a safe and simple means of providing under-vehicle access with readily-available inexpensive equipment.

Abstract: SEISMIC EXPLORATION SYSTEM INCLUDING   ANALOG-TO-DIGITAL CONVERTER USING        DELTA MODULATION            ABSTRACT          An analog-to-digital converter for use in seismic data processing applications features variants on delta modulation and delta-sigma modulation methods.  A series of single bits is output by an analog-to-digital converter based on comparison of a predicted analog signal with the actual analog signal.  A low pass filter and subsampling operation is applied to the output digital bits to provide digital words corresponding to the analog signal amplitude. Plural integrator stages are shown which allow reduction of quantization error.

Abstract: ABSTRACT A new digital procedure for generating and processing scanner-images is presented.  The terrain is scanned by an opto-electronic three-line scan camera from aircraft, missiles or spacecraft. Three linear sensor arrays are arranged in the focal plane of the camera objective per-pendicularly to the flight course.  Each sensor array produces an image strip of the covered terrain according to the push broom principle.  Nodes of the digital elevation model (DEM) to be computed are selected in the middle image strip whose object planes are nearly vertical.  The conjugate image points in the other two image strips are determined by area correlation methods.  The coordinates of all these image points and a few control points are inserted into a least squares adjustment for computing the orientation parameters of the camera along its entire flight course and the coordinates of the digital elevation model.  Rasterplots of ortho- and stereo-ortho-photos are produced after the digital rectification of the image strips, utilizing the nodes of the DEM grid.

Abstract: Abstract An NMR imaging method and apparatus are of the type in which a 180-degree RF pulse is applied to generate a spin echo after the selective excitation of a spin by a 90-degree RF pulse. A dummy gradient field that has the same direction and intensity as those of a gradient field to be applied when the spin echo is observed is applied between the 90-degree RF pulse and the 180-degree RF pulse so that the instant of starting application of the gradient field for signal observation is advanced to the extent corresponding to the dummy gradient field.  The resulting method provides compensation for image distortion due to transient response of the gradient field.

Abstract: METHOD OF MAKING ARTICLES USING GAS FUNCTIONALIZED PLASMA DEVELOPED LAYER          Abstract This invention concerns a method of making articles by the use of a resist comprising an organic layer, developed by a plasma atmosphere, for pattern delineation.  The resist is formed by sorption of an inorganic-containing gas into an organic material.  The development of the resist occurs by exposure to a plasma (e.g., oxygen reactive ion etching) that forms a protective compound (e.g., a metal oxide) selectively in the resist. The selected regions can be defined by patterning radiation of various types, including visible, ultraviolet, electron beam and ion beam.  In an alternate embodiment, the selected regions are defined by an overlying resist, with the gas sorption protecting the underlying layer in a bilevel resist.  The protective compound can protect the organic resist layer during etching of any underlying inorganic layer, such as metal, silicide, oxide, nitride, etc. (FIG. 1)
