Title: Infusing preoxidized carbonaceous fibres with non-polar plasticizer
Inventor: NELSON DANIEL C
IPC: C08J5/04
Filed: 1987-01-21
Granted: 1991-03-26
Abstract: ABSTRACT OF THE INVENTION     A carbonizable body is formed by infusing a plura-liyy of preoxidized (preferably stabilized by known pro-cessing to have about 17 to 30 weight percent oxygen) fibers prepared from pitch, in a non-polar liquid plasticizer, typically quinoline, capable of extracting a tarry leachate from the fibers.  The infusion of the fibers in the plasticizer is continued for a sufficient time for a substantial amount of leachate to form on the surface of the fibers.  The treated fibers are then con-solidated or diffusion-bonded to one another or other fibers, as by orienting the treated fibers in a mold and subjecting them to isostatic pressing at relatively low temperatures and pressure.  Further processing of the consolidated fibers with appropriate heat treatment in an inert atmosphere will produce a carbonized bulk pro-duct with higher values of Young's modulus for the car-bonized material than have been previously achieved at such carbonization temperatures.  This carbonaceous pro-duct can be truly graphitized by subsequent heat treat-ment to obtain material with a modulus of at least 40 x 106 psi, and a tensile strength of at least 20 x 103 psi.

A spring-loaded hollow annular piston (30) is slideably mounted on the exterior of central tubular cylinder (10) and within upper cylinder (28) for a downward movement against compression spring (32) to initially force a back-flow of filtered fluid through filter element (14), lifting contaminant particulate solids from its filtering surface (15).  Inlet valve opening (64) is opened to fluid flow when piston (30) attains a compressed position.          Filter element (14) is closely spaced to canister enclosure inner wall surface (9) for rapid flow of fluid over the inlet surface (15) of the filter element (14) to scour solids to sump (5) in the lower portion of the canister enclosure (3).  A lower spring-loaded piston (18) communicates with sump (5) and is forced upward by entering contaminated fluid until an attached sleeve valve piston (23) slideably mounted in tubular cylinder (10) opens to permit filtered fluid to exit the filter (1), resulting in normal filtration flow of fluid through filter element (14).

Abstract: HIGH STRENGTH CERAMIC HONEYCOMB STRUCTURE                 Abstract of the Disclosure A high strength ceramic honeycomb structure includes a number of quadrilateral cells arranged adjacent to each other.  Triangular cells are arranged in a zone in the proximity of an outer circumference of the honeycomb structure.  Partitions of the triangular cells are oblique to partitions forming the quadrilateral cells and extending substantially toward a center of the honeycomb structure.  The oblique partitions of the triangular cells serve to improve the isostatic strength of the honeycomb structure and to decrease the pressure losses.

Title: Fixing system for fastening catheters, cannules or the like to the skin surface and process for the sterile fastening thereof
Inventor: BECHER FRANK
IPC: A61M15/06
Filed: 1987-05-27
Granted: 1993-08-03
Abstract: ABSTRACT OF THE DISCLOSURE           A  fixing  system  is disclosed  for  fixing catheters, cannulas and the like.   The system includes a skin film coated with a skin adhesion layer and having a cover  film  and  an overplaster  finished with  a  contact adhesive layer adhering to the skin film and having an overplaster  cover  layer.    A  process  for  the  sterile fastening of a cannula to the skin is also disclosed which includes the steps of application of a bacteria-tight skin film with skin adhesion layer to the skin in the insertion region of the cannula, passing the cannula through the skin film, applying to the underplaster region surrounding the insertion point an adhesive forming an elastic, bacteria-tight film adhering to the underplaster with the cannula portion  projecting  out  of  the  skin,  and  sticking  the overplaster over the cannula.

Title: Continuous preparation of dialkanesulfonyl peroxide
Inventor: WHEATON GREGORY A
IPC: C25B3/29
Filed: 1987-06-16
Granted: 1992-07-14
Abstract: ABSTRACT    Dialkanesulfonyl peroxide (RSO2-O-O-O2SR) is prepared in a continuous process by electrolyzing the corresponding alkanesulfonic acid at an elevated temperature (to keep the peroxide product in solution) in a continuous-flow electrolysis cell, removing the solution from the electrolytic cell, cooling the solution to precipitate the peroxide product, and recycling the supernatant alkanesulfonic acid back to the cell.

Title: Low mass piston for aerosol can
Inventor: MALEK EDWARD J
IPC: B65D83/14
Filed: 1987-07-10
Granted: 1992-02-25
Abstract: ABSTRACT An injection-molded piston for an aerosol container has a face portion for contacting and ex-erting pressure on material to be dispensed, and a thin, flexible skirt depending axially from and cir-cumscribing the face portion for forming an effective seal against the inside wall of the container.  The outer wall of the skirt is continuous, while the cir-cumference of the inner wall has alternating areas of constant thickness along said areas and areas of minimum thickness, the curved portions forming with the outer wall a plurality of sections, the thickness and circumferential extent of each of which decrease axial-ly along the skirt toward its distal end.  The piston includes a depending extension on the skirt which aids sealing.

Title: Durable melt-blown sheet material
Inventor: EIAN GILBERT L
IPC: D04H1/56
Filed: 1987-08-05
Granted: 1991-02-12
Abstract: ABSTRACT           A durable fibrous sheet material comprised of a melt-blown fiber web having a plurality of reinforcing fibers extending therethrough is provided.  The reinforcing fibers are needled through the web of melt-blown fibers and are then bonded to fibers on the opposing faces of the layer of melt-blown fibers to hold the reinforcing fibers in position. Solid particles can be dispersed in the layer of melt-blown fibers.  Such particles are preferably vapor-sorptive particles, e.g., activated carbon, so that the sheet material will sorb vapors passing therethrough.  The sheet material is particularly useful as a component of a chemical protective garment.
