Abstract: Abstract A reel for web material such as magnetic recording tape is disclosed.  The reel may be advantageously employed in a reel-to-reel magnetic tape transport where mag-netic tape is wound under tension that is converted to radial forces which subject layers of the tape disposed over discontinuities associated with the reel hub to adversely affect the transducing relationship between the flux gap and the transducer of the recording sur-face of the tape.            The section of the cylindrical tape receiving surface which is associated with a discontinuity is formed to function as a cantilever beam with the distal end of the beam being aligned with the discontinuity.  The outer portion of the hub is made of relatively com-pressible material, while the inner portion is rela-tively solid.  Compressibility of the outer portion is enhanced by providing a plurality of circumferentially disposed cylindrically shaped openings which also function to relieve radially induced forces on the tape layers.

Abstract: ROY R. VANN, ET AL     BAR ACTUATED VENT ASSEMBLY    AND PERFORATING GUN                     ABSTRACT OF THE INVENTION  A casing gun is suspended downhole adjacent to a hy-drocarbon containing formation by attaching the gun to the end of a tubing string.  A packer device isolates the lower downhole casing annulus from the upper casing annulus.  The casing gun has a firing head located at the upper end thereof which is actuated in response to impact.  A vent assembly underlies the packer and is connected in series relationship respective to the gun firing head and the packer.  A specially constructed bar de-vice is dropped into a lubricator at the wellhead and travels down the interior of the tubing string, where the bar impacts against a sliding sleeve of the vent assembly, thereby moving the sleeve and opening a port which communicates the interior of the tubing string with the lower casing annulus.  The bar continues to travel downhole until it impacts against the firing head, thereby detonating the perforating gun.  Hence, the pre-sent invention comprehends the provision of a special weight which is dropped downhole to sequentially impact against a novel vent assembly and against a perforating gun head in rapid succession, so that a hydrocarbon containing formation can be completed in an unusual manner.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved flexible manufacturing  system comprises a plurality of computer numerically controlled machine tools, each controlled by a machine control system which is supplied with a plurality of sets of machine NC part programs and a program map from a supervisory control computer system.  Each of the machine tools is located about the perimeter of a track which carries a plurality of pallet-carrying transpor-ters, each moving under the control of a material handling system controller.  The supervisory control computer system, coupled to the control system of each machine tool and to the material handling system controller, is provided with input data indicative of production requirements, material resour-ces and system status, that is to say, the type of part car-rying pallet carried by each transporter.  In accordance with the input data supplied thereto, the supervisory control com-puter system supplies routing information to the material handling system controller which, in response, initiates movement of a transporter to a machine tool, shuttling of the part carrying pallet from the transporter to the machine tool, and execution of a selected one of the sets of machine NC part programs by the machine control system in accordance with the program map.  During intervals, when the supervisory control computer system is  inoperative, continued flexible manufac-turing system operation can be maintained by operating the material handling system controller in semi-automatic or man-ual mode.

Abstract: ABSTRACT        A process for selectively absorbing H2S from gas mixtures which contain CO2 and H2S in a molar ratio of 4:1 or greater and in which the gas flow rate varies substantially.  Alkali metal car-bonate solutions are used with absorption under pressure and at an elevated temperature and desorp-tion by steam stripping at about atmospheric pres-sure.  The degree of selectivity of H2S removal is maintained constant despite substantial variations in the gas flow rate by maintaining a constant stripping steam/gas ratio selected to provide the desired partial pressure of H2S in the purified gas and by adjusting the solution/gas ratio to a value in the vicinity of that at which the partial pressure of H2S in the purified gas remains at said selected value while the difference between the partial pressures of CO2 and H2S in the purified gas reaches a maximum value, and by then maintaining such solution/gas ratio as the gas flow rate var-ies.  The process is particularly applicable to H2S removal from hot gases produced by the pres-sure gasification of sulfur-containing coal, oil or the like which are to be used in power generation cycles.

Abstract: DOT PRINTING MECHANISM OR   DOT MATRIX LINE PRINTERS  Abstract of the Disclosure A dot printing mechanism for dot matrix line printers comprising a plurality of hammer modules (45) mounted on a carriage (43) that is shuttled back and forth along a print line is disclosed. Each module includes a plurality of cantilevered print hammers elements (47) formed of a resilient ferromagnetic material. Each of the print hammers includes an anvil (49) on one face of its cantilevered outer end, adapted to print a dot when the associated hammer is actuated. The modules (45) are mounted on opposite sides of the print line and positioned such that the hammers (47) of juxtaposed modules are interleaved and such that the anvils (49) all lie along the print line. Further, each hammer forms part of a magnetic circuit that includes a permanent magnet (51), a post (57) and ferromagnetic paths between the permanent magnet and post. The post supports a coil (59) and is positioned near the cantilevered end of the print hammer (473, on the side opposite of the anvil (49). In the absence of current through the coil (59), the print hammer (47) is attracted to the post by the magnetic field produced by the permanent magnet (51) and, thus, cocked. The cocked hammers (47) are selectively released to create dots by the selective energization the coils. The selective energization is such that the coils (59) produce a magnetic field that counteracts the magnetic post attraction force created by the permanent magnet (51).

Abstract: TOUCH POSITION LOCATING SYSTEM            Abstract A system providing greater accuracy of touch location and better rejection of noise comprises a plurality of force sensing detectors for detecting and generating electrical signals proportional to the applied touch.  Alternating current coupling circuits reshape the electrical signals from each detector for accentuating the common dynamic frequency characteristics of the variety of forces presented to the system.  A sample collection circuit sequentially collects samples from each AC coupling circuit until a predetermined interval of time lapses or until the second zero crossing of one electrical signal sample is detected, whichever event occurs first.  Samples are averaged before calculating the location of the touching force.  An average reference level for each force sensing device is established prior to the collection of the force samples to automatically adjust for any changes in the condition of the system.

Abstract: ABSTRACT OF THE DISCLOSURE An impact printing device having a plunger-type magnet system has an armature consisting of two joined portions which are a cylindrical principal portion and a guide portion which serves as the printing hammer.  The principal portion of the armature consists of material of high magnetic permeability and carries a cylindrical peg thereon which mates with a corresponding receptacle in the printing hammer, which is comprised of non-magnetic material.  The principal portion and the peg thereon terminate at sharp edges which cause the magnetic lines of force to converge at those edges thereby increasing the kinetic energy available for moving the armature during a printing stroke.  A position sensing means is connected to a drive circuit for the magnet system for controlling deceleration of the armature during a return after a printing stroke in accordance with the speed of the returning armature.
