Abstract: METHOD AND APPARATUS FOR PROCESS CONTROL OF      VERTICAL MOVEMENT OF SLURRIED PARTICULATES            ABSTRACT OF THE DISCLOSURE    A process control system for use in movement of slurry material from a first lower level through a vertical flow way to an upper or surface level.  In particular, this system is utilized for moving slurried particulate from a subterranean mine level upward through a vertical flow way such as an earth borehole to a surface pumping station or the like.  The vertical pump system includes series-connected pumps having variable speed capabilities at the lower level, and the pumps then direct the slurried material through the vertical flow way to an upper level receiving station.  The process control monitors the upper level volume, the slurry line pressure in the pipeline underground, and the flow rate in the pipeline underground thereby to select a controller output signal.  The output signal is then utilized to control a hydraulic servo mecha-nism which adjusts the variable speed drive to one or more of the series-pumps thereby to maintain a proper flow rate and pressure through the vertical flow way.

Abstract: "BIMETALLIC WELL SCREEN FOR USE IN INJECTION WELLS AND METHOD OF MAKING SAME"                            ABSTRACT           Mounting arrangement for a bimetallic pipe base well screen which must operate at elevated temperatures includes a pair of expand-able end boss rings at the ends of a cylindrical screen member.  The end boss rings overlie unperforated portions of the outer surface end portions of an internal pipe member which has perforations along a portion of its length which underlie the well screen.  The screen mem-ber and the end boss rings have a greater temperature coefficient of expansion than the pipe base.  At room temperature, the end boss rings have a smaller inner diameter than the outer diameter of the pipe base.  The boss ring portions are heated and shrunk-fit onto the pipe base to a degree that at operational temperatures they will either expand slightly out of contact with the pipe base, or at least become substantially unstressed, thus preventing damage to the screen member while also blocking out the entry of particles.  The arrangement is particularly useful where many screen sections are used in a string since the screen members can remain fixed in position in a gravel packed well while the pipe base sections can move up and down inside them in response to temperature variations.

Abstract: TIEBACK CONNECTION METHOD AND APPARATUS            Abstract of the Disclosure A   tieback   connection   apparatus   effects metal-to-metal  type  seal  between  a  riser  run  from  an overhead vessel and a subsea well casing suspended from a casing hanger in a subsea wellhead member.   The apparatus includes a  tubular mandrel  connected  to  and  run  by the riser into the wellhead, and a metal-to-metal type annular seal mounted at the lower end of the mandrel.  The end  of the mandrel  is positioned  in coaxial  alignment  with  the casing  hanger  with  the  seal  ring  position  between  the mandrel and the hanger to effect a seal between the riser and  the casing when compressive force  is applied  to  the seal  ring.   A seal activating mechanism, associated with the mandrel and  operated  by a tool  run from  the vessel, engages the casing hanger and applies the compressive force to effect the seal.  The seal activating mechanism includes a locking collet, a reaction sleeve, and a drive sleeve. Rotation of the drive sleeve by the operating  tool moves the  reaction  sleeve  into  contact  with  the  collet  to maintain locking engagement between the casing hanger and the collet.   The collet also prevents further movement of the reaction sleeve whereby further rotation of the drive sleeve causes the reaction sleeve to apply the compressive force  to  the mandrel,  seal  ring  and  casing  hanger.   A method is also provided for effecting a metal-to-metal type seal between the riser and the casing.

Abstract: A seam for joining the ends of a fabric to form an endless belt which can be used for paper making, is created by attaching a continuous coil to each fabric end, the loops of the coils being preformed so that when the loops are intermeshed each loop of one coil engages or creates an interference fit, with two loops of the opposite coil. To strengthen the seam, a pin is inserted in the tube formed by the intermeshed loops. The loops are joined by using a tool which has two channels through which the ends are brought together. The channels are formed between two plates attached to the ends of scissor arms.

Abstract: SWITCHED-CAPACITOR CIRCUIT                ANALOG-TO-DIGITAL CONVERTER                Abstract of the Disclosure A switched-capacitor analog-to-digital converter implements a conversion scheme involving execution of an algorithmic technique of successive-approximation compris-ing a number of iterations dependent upon the conversion resolution desired.  The algorithm used requires analog processing to produce an output voltage that is two times the output voltage resolved to realize the previous bit.          The "times two" function is realized by adding the voltage of the last iteration to itself (i.e., V + V = 2V).  This is accomplished by storing the output voltage resolved into the previous bit and separately storing a voltage corresponding to that voltage.  Both stored voltages are then transferred to an integrator circuit which adds the two voltages and produces the output voltage to be resolved into the next bit.

Abstract: ABSTRACT OF THE DISCLOSURE            Device for stabilising and aiming an antenna, more particularly on a ship.  The device, which can be used on merchant vessels having only a course reference, comprises on a base a mounting having bearing orientation means and supporting a gyroscopic assembly with two degrees of freedom, whose outer cardan transmission has an axis X of rotation per-pendicular to the bearing axis, its inner cardan transmission having an axis Y of rotation at right angles to the axis X and being connected to the antenna during aiming.  The gyroscopic assembly comprises a single flywheel of conside-rable kinetic force in relation to the inertia of the antenna. Each cardan transmission has a torque motor controlled by a loop whose feedback signal is delivered by an orientational pickup of the other cardan transmission.  The means for orien-tation around the bearing axis are adapted to ensure substan-tially the aiming of the antenna in bearing, and therefore to retain the gyroscopic assembly close to the canonical position.
