Abstract: ABSTRACT OF THE DISCLOSURE     An improved valve system for obtaining access to a container of fluid.  In a container of fluid, and particularly a keg for beer, a valve assembly receiving member or keg neck extends from the top of the container.  A sealing mechanism is provided to secure the valve assembly in sealed relationship with the keg neck and to allow access to the fluid contained by actuation of the valves.  More specifically, the valve neck has a groove in its inner surface to receive a resilient retainer ring which maintains the valve assembly in place.          In addition, a safety feature is provided to prevent inadvertent expulsion of the valve assembly should the retainer ring be dislodged while the keg is pressurized.  A siphon tube extends from the valve assembly to a position adjacent the bottom of the keg when the valve is secured within the keg neck.  The bottom portion of the tube is configured to enhance the flow of fluid into and out of the tube as well as carry a spring member for cooperating with one of the valve members in the valve assembly.  An improved coupler mechanism is employed in operating the valves while avoiding inadvertent opening and closing of the valve assembly.  A handle is provided on the coupler for moving the valve actuating elements between an open and a closed position.  A locking mechanism on the coupler prevents engagement and disengagement of the coupler while it is in the open position.

Abstract: A B S T R A C T           This invention is concerned with a pneumatic seeder of the type having a container for seed and a source of compressed air, each connected to a tubular conduit to cause seed from the container to be conveyed through the tubular conduit by a flow of air.  A distributor head joined to the tubular conduit distributes the seed to a plurality of smaller conduits extending in directions which are radial extensions to the tubular conduit.  These smaller conduits in turn communicate with one or more seed outlets.  The purpose of the invention is to provide a more even distribution of the seed as between the smaller conduits by not only deflecting the seed inwardly but also imparting a swirling motion to the seed.  This is achieved by providing means such as a helical ridge or a spring within the tubular conduit adjacent to the distributor head to provide both the inward deflection and the swirling motion.

Abstract: METHOD AND APPARATUS FOR ARRANGING   SCANNING HEADS FOR INTERLACING     Abstract of the Disclosure For any selected total number of scanning heads and a required minimum spacing between the scanning heads, the scanning heads are arranged in one or more arrays to read or write substantially parallel lines on a medium or surface at closer distances than the center to center distance of adjacent scanning heads in the indexing direction.  The scanning heads in any array do not have to be spaced uniform distances from each other.  When the scanning heads are arranged in more than one array, each of the arrays is spaced an arbitrary distance from the adjacent array in the pass direction.  To arrange the scanning heads for interlace scanning, they are initially arranged in a single line in the indexing direction with their centers spaced from each other the same distance as the centers of the parallel lines, which are being read or written.  Then, some of the scanning heads are shifted in at least one of the pass and indexing directions with any shifting in the indexing direction being a pitch distance or a multiple thereof.

Title: Coal liquefaction process employing  multiple recycle streams
Inventor: CARR NORMAN L
IPC: C10G1/00
Filed: 1979-06-14
Granted: 1982-10-05
Abstract: ABSTRACT OF THE DISCLOSURE         In a coupled coal solvent liquefaction-gasification system wherein a recycle mineral residue-containing slurry is mixed with the raw coal feed slurry for the liquefaction zone, the resulting feed slurry is under a pumpability total solids level constraint.  Where a coupled system is operating under such a total solids level constraint for the feed slurry, any increase in the mineral residue recycle rate relative to the coal feed rate advantageously provides a catalytic activity and selectivity advantage in favor of liquid coal product at the expense of higher and lower boiling products.  It is shown herein that this activity and selectivity effect is enhanced with decreasing liquefaction zone residence times.  In accordance with the present invention, the ratio of recycle mineral residue to feed coal is enhanced by recycling a second mineral residue-containing slurry to the liquefaction zone independently of the raw coal feed slurry.  The amount of solids in the second recycle slurry can be established to compensate for a progressive reduction in solids level in the process slurry due to the dissolving of feed coal so that the process slurry continues to maintain the maximum total solids constraint in spite of progressive coal solvation.

Abstract: (Case No. 7035) ABSTRACT OF THE DISCLOSURE    A pair of on-board processing units, operating in parallel, are supplied with input signals representing actual train speed, advance traffic conditions, and selected train parameters.  Each unit continuously calculates a maximum train speed from which emergency braking will stop the train within the indicated clear track distance ahead.  Each unit also compares the calculated maximum speed with actual train speed and emits a preselected distinctive frequency signal or a d.c. signal as actual speed is less than, or equals, or exceeds maximum  speed, respectively.  A logic network with parallel filter-rectifier circuit paths passes the unit outputs, if of the preselected frequencies, to a two-input AND gate whose output holds emergency braking released.  If a preselected frequency output is absent from either or both units, due to actual speed equaling or exceeding maximum speed or to a fault condition in the apparatus, the corresponding lack of an AND gate output actuates emergency braking.  Each processing unit monitors operation of the other unit so that, if a malfunction is detected, the operable unit, when input speed signals are within limits, also emits a second signal of the other unit frequency.  This is passed through a separate filter rectifier circuit within the logic network and applied to the second input of the AND gate to maintain train movement.

Abstract: ABSTRACT                "FIRESAFE FLUID CONTROL VALVE"     A valve member 17 when positioned so as to prevent fluid flow through a passage 11 in a valve body 10 engages a ring 14 made of flexible resilient fluorocarbon synthetic resin material, the ring 14 providing a fluid-tight seal between the valve member 17 and a seat 12 on the body 10.  In the event of the ring 14 failing, the valve member 17 engages a back-up ring 15 made of a high temperature, non-metallic material which is non-galling, such as graphite.  The high temperature properties of the ring 15 thus enable the valve to remain fluid-tight when shut even if the flexible ring 14 is destroyed by fire.  The ring 15 can be compression-formed in situ into a shape which ensures close contact with the valve member 17.  In the event of the ring 15 also failing, the valve member 17 comes into contact with a metallic ring 13 from which it is normally spaced and thereby restricts the flow of fluid through the valve. This arrangement can be applied to butterfly-type valves (Figure 1) as well as to ball-type valves (Figure 4).

Abstract: Iron rich dusts created during steelmaking, as in the basic oxygen and open hearth processes, are useful for scavenging hydrogen sulfide.  For example, basic oxygen furnace dusts, which are in more abundant supply, are found to consist of fine, nearly spherical particles of iron oxide whose crystalline composition comprises Fe3O4 (major portion) and Fe2O3 (minor por-tion) as seen by X-ray diffraction.  Their great surface area makes them highly reactive to hydrogen sulfide gas.  Their reaction yields unexpected products, namely, free sulfur and iron hydroxides.  According to the present invention such iron rich dusts are used in water based drilling muds to scavenge hydrogen sulfide encountered in well drilling.
