Abstract: ABSTRACT OF THE DICLOSURE              There is provided in accordance with the invention apparatus and a method for boring holes through carbonaceous deposits.  The method involves the step of introducing combus-tion-supporting gases such as air under pressure through the apparatus installed in a well hole opposite the area to be bored.  The apparatus comprises inner and outer flexible tubes with flexible, jointed armour and a directional nozzle which permits it to be bent and change attitude as necessary.  The adjacent carbonaceous interface after being ignited is main-tained in this condition by the combustion-supporting gas which is supplied under pressure.  As the combustion proceeds, the pressure expels the combustion products and the gas injec-tor is advanced along the channel it has previously formed.

Abstract: GUIDE-CONNECTOR ASSEMBLY FOR JOINING            OPTICAL FIBERS     Abstract of the Disclosure A guide member and an assembly of a guide member and connector for making an optical signal transmissive connection between the ends of a pair of single optic fibers are provided together with the method of making the guide member.  The guide member is in the form of at least three predetermined length glass rods disposed in a side-by-side array and connected together along peripheral portions to form a smooth, cusp-shaped interstitial channel therebetween.          The ends of the guide member's channel are open and preferably are of greater cross-sectional area than the intermediate portion of the channel to facilitate entry of an optic fiber into the channel.  The guide member is disposed within a cavity in the connector.  The connector is formed of a pair of mating connector members.  Each member includes a first and second end with a passageway extending longitudinally therebetween and through which a respective fiber passes entering the guide member.          Each of the passageways includes an enlarged opening adjacent to the first end and tapering downward in cross-sectional area toward the entrance to the cavity.  The cross-sectional area of the passageway at the entrance to the cavity is only slightly larger than the cross-sectional area of the optic fiber to accurately position the fiber extending therethrough and into the guide member.  One or both of the connection members may include an alignment aperture to provide visual access to the interior of the cavity to ensure that each fiber is extended a predetermined distance therein such that when the connection members are connected together the fiber ends abut within the guide member in a good optical signal transmissive joint.

Granted: 1981-11-24
Abstract: ABSTRACT OF THE DISCLOSURE           Instructions which are read from a program memory included in a control computer employing indirect addressing of a data memory are stored temporarily and sequentially in a buffer memory to form an execution queue.  The absolute address to the data memory is generated by an address calculator by means of a base address derived from a reference memory in correspondence to an input address and by means of at least one address parameter which has been recorded in a register memory in connection with the execution of an instruction read from the buffer memory and transferred to a parameter register prior to the address calculation.  In addition to each instruction, information is recorded in the buffer memory to indicate on one hand whether the instruction is of the type which performs a write or read operation in the data memory and on the other hand whether it is of the type which enters address parameters in the register memory.  This additional information is continually monitored and, when it shows that the parameters will not be changed by any instruc-tion in the queue in front of a write or read instruction which has entered the queue, the required address calculation process is initiated.

Abstract: METHOD OF OBTAINING NICKEL COATED FILLED EPOXY RESIN ARTICLE                       Abstract Electroless nickel coating of epoxy resin foundry patterns and core boxes can be carried out without a palladium chloride/ stannous chloride activation of the surface, if the pattern or core box contains a high density of metal particles which act as "keying" sites, and if the metal-filled resin surface is properly prepared.  The preparation steps include a very light abrading with a fine (minus 60 U.S. mesh and preferably even finer) grit and a very brief acid pickling step.  The electroless-plated article has a continuous coating of nickel bonded essentially directly to the resin through the metallic "keying" sites.

Abstract: HOMOPOLAR MACHINE FOR REVERSIBLE              ENERGY STORAGE AND TRANSFER SYSTEMS     ABSTRACT OF THE DISCLOSURE A homopolar machine designed to operate as a generator and motor in reversibly storing and transferring energy between the machine and a magnetic load coil for a thermo-nuclear reactor.  The machine rotor comprises hollow thin-walled cylinders or sleeves which form the basis of the system by utilizing substantially all of the rotor mass as a conductor thus making it possible to transfer substantially all the rotor kinetic energy electrically to the load coil in a highly economical and efficient manner.  The rotor is divided into multiple separate cylinders or sleeves of modular design, connected in series and arranged to rotate in opposite directions but maintain the supply of current in a single direction to the machine terminals.  A stator con-centrically disposed around the sleeves consists of a hollow cylinder having a number of excitation coils each located radially outward from the ends of adjacent sleeves.  Current collected at an end of each sleeve by sleeve slip rings and brushes is transferred through terminals to the magnetic load coil.  Thereafter, electrical energy returned from the coil then flows through the machine which causes the sleeves to motor up to the desired speed in preparation for repeti-tion of the cycle.  To eliminate drag on the rotor between current pulses, the brush rigging is designed to lift brushes from all slip rings in the machine.

Abstract: ABSTRACT OF THE DISCLOSURE         An ultrasonic scanner for producing a sector scan in an object to be examined in which one or more ultrasonic transducers traverse an arcuate path with respect to a reflector which is positioned to receive the ultrasonic waves scanning the surface of the reflector from each of the transducers and coverge such waves at a point a preselected distance in front of the reflector.          In general, the ultrasonic waves are converged at a point outside the scanner and inside the object to produce a sector scan in the object having its center at the convergence point,  In one embodi-ment of the scanner the reflector only partially reflects the ultrasonic waves and an additional stationary transducer is pro-vided which is positioned to produce ultrasonic waves which radiate through the reflector and coincide with one of the lines of the sector scan, thus permitting simultaneous M-mode or pulse Doppler echo information to be obtained in perfect registration with the sector scan lines.  Attenuation, absorbtion and anti-reflection means are provided to suppress echo artifacts.

Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed a liquid velocity measuring apparatus compris-ing an actuable generator for providing a relatively high frequency signal to a transmitting transducer for directing an ultrasonic wave into a conduit through which liquid is directed.  A receiver transducer is disposed to receive the acoustical wave as reflected from the liquid, and to provide an output signal to be amplified and demodulated to provide a train of high frequency pulses, the frequency of which is indicative of the velocity of the liquid directed through the conduit.  The train of pulses is applied to a counter and decoder for respectively counting and decoding the pulses to provide a signal to a display whereby a digital indication of the liquid velocity is given.  Further, a timing circuit is provided for enabling the generator, the counter and the decoder for a first, relatively short period of time, made dependent upon the cross-sectional area (or diameter) of the conduit through which the liquid is directed, and for energizing the display for a second, relatively long period of time to permit reading of the dis-play.
