Abstract: ABSTRACT OF THE DISCLOSURE      The method of thermal-mine oil production includes providing a system of mine workpings and at least one operation gallery. Drilling production wells from the gallery into the upper and lower portions of the oil--bearing bed. Drilling from the gallery injection wells into the central portion of the oil-bearing bed. Positively feeding a heat carrier via the injection wells into the central portion of the oil-bearing bed, for uniform distri-bution of the heat carrier throughout the body of the oil-bearing bed and forcing oil therefrom into the said production wells. And then the method includes collecting the oil from the upper and lower portions of the oil-bea-ring bed through the said production wells in the operation gallery and directing the oil from the operation gallery through the mine workings to the ground surface.

Abstract: ABSTRACT OF THE DISCLOSURE           In an integrated fluid coking and gasification process wherein a stream of fluidized solids is passed from a fluidized bed coking zone to a second fluidized bed and wherein entrained solid fines are recovered by a wet scrubbing process and wherein the re-sulting solids-liquid slurry is stripped to remove acidic gases, the stripped vapors of the stripping zone are sent to the gas cleanup stage of the gasification product gas. The improved scripping in-tegration is particularly useful in the combination coal liquefaction process, fluid coking of bottoms of the coal liquefaction zone and gasification of the product coke.

Abstract: ABSTRACT OF THE DISCLOSURE             The invention enables the scoring and breaking out of a pair of glass blanks from a single sheet of glass in a rapid and efficient manner.  Apparatus is provided which carries out a method including the steps of applying first and second score line patterns to a single piece of glass, which patterns define, at least in part, the outlines of glass blanks to be subsequently broken out from the piece of glass. Following this operation, forces are applied to the piece of glass in such a way as to sever the glass along a portion of one of the score lines and to split the piece of glass into two parts each having a respective one of the patterns thereon. The glass parts are then separated a selected distance away from one another and thereafter breakout forces are applied to the glass parts to sever such parts along their respective score line patterns.

Abstract: ABSTRACT     A clamping head carried upon a shaft and mounted rotatably in a frame has a flanged mandrel on which a sleeve carrying a roll of material is adapted to be clamped.  The mandrel carries, between its flange and the end of the sleeve, a ring which is displaceable axially upon the mandrel to strip the sleeve.  The frame carries an actuating mechanism which acts upon the said ring for the purpose of stripping the sleeve from the mandrel.  The actuating device comprises a pressure element, having a drive, which in its inoperative position bears against abutments on the frame.  The collar of the ring comprises at least two points, equally distributed around the periphery thereof, in which the ring is freely rotatable when the pressure element in in the inoperative position.

Abstract: Abstract of the Disclosure A rotary rock bit is constructed having rolling cutter members for forming a borehole in the earth.  Each rolling cutter member includes an annular row of cutting elements for cutting portions of the borehole.  The cutting elements comprise cutting teeth or cutting inserts.  Varied pitches are provided between the inserts/teeth.  The pitches between pairs of inserts/teeth are varied so that the pitches between no two pairs of inserts/ teeth in a row or group are the same.  Since no two pairs of inserts/teeth have the same pitch, the probability  of tracking will be remote.  This increases the rate at which the bit penetrates the formation and generally decreases the probability of insert/ tooth breakage therein.  The present invention reduces or eliminates tracking and stumbling encountered in prior art earth boring bits.     -1a-

Abstract: ABSTRACT           Method and apparatus are disclosed for optically scanning and recording information on railroad cars moving at high speed to facilitate identification of the cars.          The apparatus comprises equipment at track-side and at a remote location (usually, the yard).  At track-side, there may be provided various detectors to sense the approach, proximity, speed, and direction of travel of a train. circuitry is provided to control operation of a camera focused on a passing train in response to information from the detectors.  At the remote location, the optical signal from the camera is viewed immediately or recorded for later playback, at reduced speed if necessary, so that a human operator can read the identifying information on the sides of the train cars.  The apparatus provides a completely automatic economical and reliable method for determining which railroad cars are in a train.  No special coded labels must be put on the cars (as with many other systems) nor must passing trains be slowed to permit accurate reading.

Refraction occurs only for a ray going from the higher to the lower refractive index medium.  Rays entering the higher refractive index medium from the lower are never refracted since the optical surface is always chosen to have its center of radius coincident with the  object or image being optically operated on by the lens.  The system can be used to magnify the image of an object, the object being most any two-dimensional representation such as a negative or a positive print.  The object might alternatively be a light source or an external object whose rays are imaged onto an embedded light sensor so that the functions of the source or sensor respectively can be enhanced by the optical system.

Abstract: RELEASABLE COUPLING            Abstract of the Disclosure A high strength releasable coupling particularly adapted for quick and simple interconnection of pipe or piling sections has mating cylindrical male and female members releasably interlocked by multiple locking pins passing tangentially through the members.  The pins are received within spaced sets of complemental bores in the female member and extend partially through a corresponding annular groove formed in the male member whereby the members may be locked together in axial alignment without requiring rotation about their axes.  The arrangement of the bores in each set is such that the axes of the pins circumscribe the male member when the members are interlocked thereby evenly distributing axial loads on the coupling while also providing superior endurance to bending loads.  In preferred forms each set of bores is angularly offset about the axes of the members relative to the other bore sets for improved loading.

Abstract: ANALOG-TO-DIGITAL CONVERTER                       ABSTRACT      An analog-to-digital conversion system uses a fast analog-to-digital converter having a resolution less than the system resolution to convert the difference between a previously predicted value and the current analog value.  The converted difference is summed with the predicted value to compute the actual value of the analog input signal to a resolution greater than that of the fast analog-to-digital converter  The high resolution digital value thus obtained becomes the predicted value for the next conversion. This predicted value is converted by a digital-to-analog converter, having the same accuracy but not the same resolution as the system output, to an analog signal which is compared with the input analog signal to obtain a differ-ence signal.  This difference signal is sampled and held to provide the input to the fast analog-to-digital converter. The system includes a gain scaling and switching circuit to compensate for errors which would otherwise occur when the difference between the true analog input and the prediction exceeds the range of the low resolution, fast analog-to-digital converter.
