Patent number: 4864852Abstract: Method and apparatus for measuring the cut resistance of flexible materials, such as films, fabrics, felts and papers. A flexible material is wrapped around a mandrel that is rotated at a predetermined speed. A cam attached to the rotating mandrel allows a cutting edge, such as a razor blade, to repeatedly fall on the material covering the mandrel. The cutting edge repeatedly contacts the material, in the same location and with the same predetermined force, until the cutting edge penetrates the material and makes electrical contact with the mandrel. When edge-to-mandrel contact is made, the rotation of the mandrel is automatically stopped. The number of rotations (i.e. cutting cycles) required to penetrate the material is noted and used as a measure of the relative cut resistance of the material.Type: GrantFiled: July 25, 1988Date of Patent: September 12, 1989Assignee: Allied-Signal Inc.Inventor: Mark B. Boone

Patent number: 4802268Abstract: A tow of continuous filaments is fed by aspiration into a stream of compressible fluid. The stream containing the filaments is directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the compressible fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass of the tow and emerge from the chamber in crimped form.Type: GrantFiled: November 19, 1982Date of Patent: February 7, 1989Assignee: Allied-Signal Inc.Inventors: Hsin L. Li, Hendrikus J. Oswald, Alfred L. Liland

Patent number: 4764607Abstract: Method and improved apparatus for recovering a volatile organic material, such as caprolactam, from a liquid mixture of organic and inorganic materials are disclosed. The method features the step of mixing the liquid mixture with superheated steam for 0.005 to 1.0 second to vaporize a large portion of the volatile organic material without degrading the organic materials. The steam and vaporized organic materials are then separated from the liquid mixture remaining, followed by separation of the vaporized organic material from the steam. The vaporized organic material subsequently is condensed. The improved apparatus features means for introducing superheated steam into a vaporizer feed pipe, as well as means for mixing the superheated steam with the liquid mixture in the pipe for 0.005 to 1.0 second so that a large portion of the volatile organic material is vaporized and feeds with the steam and remaining liquid mixture into the vaporizer for separation.Type: GrantFiled: December 22, 1986Date of Patent: August 16, 1988Assignee: Allied CorporationInventors: Laszlo J.
