Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed herein is a device for checking that the bands joining filters to cigarettes have been sealed down, wherein through first pneumatic means, the cigarettes placed side by side inside housing defined by transfer means, are thrust towards opening aligned axially with the said housing, the section of which is slightly greater than that of the individual cigarette.  Opposite the said first pneumatic means there are first means for halting the cigarettes that pass through the said openings with only the part around which the filter-cigarette joining band is wound.  Downstream of these there are means for intercepting and ejecting cigarettes having an open band which do not arrive against the said first halting means and after these, second pneumatic means that operate in the opposite direction to the first pneumatic means, opposite which there are second means for halting the cigarettes moving inside the housing defined by the transfer means under the action of the said second pneumatic means,which return the checked cigarettes to their initial alignment.

Abstract: ABSTRACT      A method of mining thick seam materials is performed by forming a pair of generally horizontal, vertically spaced, vertically aligned passes or drifts in one side of the thick seam.  A number of contiguous vertical holes are drilled in the material from the lower to the upper drift to form a relatively large opening extending the length of the drifts. This large opening is then filled with low grade concrete to support the overburden and, after the concrete is set, a second pair of generally horizontal, vertically spaced, vertically aligned drifts are formed adjacent to the first mentioned drifts and the foregoing process is repeated.  The above steps are continued until the entire seam of material has been removed.  Each individual hole between an upper drift and a lower drift is formed by first drilling a relatively small diameter hole from the upper drift to the lower drift, following which a relatively large diameter reamer bit is then coupled to the drill shaft and the drill shaft is raised and rotated to cause the reamer bit to mine the materials from the bottom drift to the top drift, the materials falling into the lower drift and being removed in any suitable manner.

Abstract: ABSTRACT OF THE DISCLOSURE A thermotropic wholly aromatic polyester is provided which is cap-able of forming an anisotropic melt phase.  This novel polyester displays surprising tractability and may be used as a molding resin or may be melt spun into fibers.  The aromatic polyester of the present invention consists essentially of the recurring units (a) 2,6-dioxyanthraquinone moiety, (b) 4-oxybenzoyl moiety, and (c) aromatic diacid moiety. The resulting poly-ester exhibits a melting point below approximately 375°C, and preferably be-low approximately 350°C. Fibers which are melt spun from the polyester ex-hibit unexpectedly good thermal stability.  The desirable tractability prop-perties of the polyester are attributed to its anisotropic melt phase, which is due to the inclusion of the 2,6-dioxyanthraquinone moiety in the polymer.

Abstract: METHODS FOR PREPARING ANISOTROPIC MEMBRANES        AND MEMBRANES PRODUCED THEREFROM              ABSTRACT OF THE DISCLOSURE      Anisotropic membranes are prepared from a solution of a membrane-forming polymer in a liquid carrier.  The polymer solution is provided in the form of a precursor and is then coagulated in a liquid coagulant comprising water to form the anisotropic membrane.  The liquid carrier used in the methods comprises an N-acylated heterocyclic solvent which can be represented by the structure:                          wherein X is -CH2-, -N(R')- or -O-; R is hydrogen, methyl or ethyl; and R' is hydrogen or methyl.  The methods are particularly useful for preparing anisotropic hollow fiber membranes.  In forming anisotropic hollow fiber membranes, the solution of hollow fiber-forming polymer in the liquid carrier is extruded through an annular spinnerette to form a hollow fiber precursor, and the hollow fiber precursor is coagulated in a liquid coagulant comprising water to form the hollow fiber membrane,  The methods are attractive for producing polysulfone hollow fiber membranes which have a homogeneously-formed, thin selective skin on an open cellular support and which exhibit high resistance to collapse.  The membranes are especially useful for the separation of gases,
