Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for applying surgical fasteners has an applicator mechanism, with an anvil for applying the fasteners to tissue and a shaft connecting the applicator mechanism to an actuator mechanism.  The shaft is flexible to bend during insertion into a body channel to conform to the configuration of the body channel and is capable of retaining said configuration during actuation.  The shaft transmits a first, relatively small force from said actuator mechanism to the applicator mechanism hydraulically, and comprises a first sleeve within a second sleeve.  The actuator mechanism comprising a slide secured to the first sleeve for moving the anvil. Responsive to the first force, the applicator mechanism produces a second force larger than the first force for applying the fasteners to tissue.

Abstract: Abstract of the Disclosure An improved-steering apparatus includes a piston and cylinder type motor having a hollow piston rod extending out of one end of a motor cylinder.  Since the piston rod extends out of only one end of the motor cylinder; the working area on the head end of the piston is greater than the working area in the rod end of the piston.  The head end working area is exposed to fluid pressure during turns in one direction and the rod end working area is exposed to fluid pressure during turns in the opposite direction. A compensator chamber is provided in the hollow piston rod.  The compensator chamber has a working area on the rod end of the piston.  The compensator chamber working area is exposed to fluid pressure during turns in both directions.  The size of the compensator chamber working area is equal to the cross sectional area of a tubular wall of the piston rod.  Since the compensator chamber working area is the same size as the cross sectional area of the piston rod and is on the rod end of the piston, exposing the compensator chamber working area to fluid pressure during turns in both directions tends to equalize the steering forces in both directions.

Abstract: Abstract:      Microfibrous, polymeric filter sheets and filter elements prepared therefrom comprised of a normally hydrophobic, microfibrous, polymeric web, wherein the surfaces of the microfibers making up the web are coated with a cured, precipitated, cationic, thermo-setting binder resin or polymer.  The filter sheet is further characterized by being hydrophilic and having a positive zeta potential.    The process for preparing such filter sheets comprises four steps:    (1) applying a first solution or dispersion of a precipitating agent to a hydrophobic web to at least partially wet the web;    (2) applying a second solution of the binder resin or polymer to the wetted web of step (1); (3) working the wetted web of step (2) to mix the first and second solutions, thereby facilitating the precipitation of the binder resin or polymer and the distribution of the precipitated binder resin or polymer as a coating on the surface of the micro-fibers making up the worked web; and (4) drying and curing the coated web of step (3) to form the desired filter sheets.    The filter sheets have enhanced mechanical strength, are hydrophilic, have positive zeta poten-tials over the pH range of from about 3 to about 10 and typically have absolute pore ratings of from about 0.5 to about 80 micrometers.

Abstract: ABSTRACT        Apparatus is disclosed which is adapted for connection to a drilling conduit beneath a drilling rig floor for diverting pressurized well bore fluid in the conduit from the rig and sealing the annulus between a pipe or other object and the conduit or closing the vertical flow path of the conduit in the absence of any object in the conduit.  The apparatus includes a housing, an annular packing element and two annular pistons.  The housing is provided with two outlet passages in its wall.          A first piston covers one outlet passage in the housing wall for preventing fluid communication between that outlet passage and the interior of the housing when it is in a nonactivated position and for aligning a first hole in the piston wall with the outlet passage for allowing fluid communication when the piston is in an activated position.  The piston also serves to allow fluid communication between the second outlet wall passage and the interior of the housing via a second hole in the piston wall when the piston is in the normal position and to prevent fluid communication therebetween when the piston is in an activated position.        Sequencing means are provided to insure that the second piston in the housing is moved axially upwardly sufficiently to urge the annular packing inwardly into sealing engagement with a pipe or other object in the bore only after the first piston closes the second outlet wall passage and opens the first passage.        Permanently mounted support members are provided below the rig support structure of the rotary table into which the diverter is inserted.  Cooperative alignment means are provided in the diverter and the support member in order that the outlet passages of the diverter may automatically mate with permanently mounted vent and flow lines.       A seal member in the housing wall seals about the housing outlet to the first piston on the inside of the housing wall and to the permanent support member on the outside of the housing wall.

Abstract: ABSTRACT      An apparatus for packaging cigarettes includes a magazine for supplying cigarette groups to pockets of a first revolver, whereafter they are transferred into foil lined pockets of a second revolver and then into paper lined pockets of a third revolver.  The revolvers are continuously driven, and the groups are always oriented with their wide front or rear faces outermost in the pockets to implement smooth tangential transfer between the revolvers.  A curved stripper and guide bar enters through the sides of the first revolver pockets to transfer the groups to the second revolver.  Transfer between the second and third revolvers is made by simultaneously decreasing the radial depth of the second revolver pockets and increasing the radial depth of the third revolver pockets at a transfer station.

Abstract: Abstract:         For manufacturing trans-1,1,2,3,4,4-hexabromo-2-butene by the bromination of diacetylene, the diacetylene is first dissolved in residual hydrocarbons derived from acetylene manufacture in a solvent containing hydroxyl groups.  In a first desorption stage a mixture rich in vinylacetylene is first separated by means of an inert gas, followed by the desorption of a gas mixture rich in diacetylene with an inert gas in a second desorption stage. The gas mixture rich in diacetylene is brominated into trans-1,1,2,3,4,4-hexabromo-2-butene in a reactor in which excess bromine is provided, dissolved in a halogenated hydrocarbon at temperatures of 20 to 40C.  The discharge gas containing bromine is optionally converted in a post-reactor with excess diacetylene in a halogenated hydrocarbon to render the discharge gas bromine-free.
