Title: Method for making bicomponent fibers
Inventor: TABOR RICKY L
IPC: D01F8/06
Filed: 1990-08-07
Abstract: A method is disclosed for making thermoplastic bicomponent fibers by contacting under thermally bonding conditions (a) a first component being at least one high performance thermoplastic polymer, such as PET, PBT, nylon or the like, and (b) a second component which is olefinic and which forms at least a portion of the fiber's surface characterized by (b) including at least one grafted linear ethylene polymer having pendant succinic acid or succinic anhydride groups; whereby the fiber is dyeable. The bicomponent fibers made by this process can be in a variety of shapes (e.g., round, oval, trilobal, flat, or hollow) and configurations (e.g., symmetrical sheath/core or side-by-side or asymmetrical crescent/moon). The succinic acid or succinic anhydride groups are provided by grafting, respectively, maleic acid or maleic anhydride onto the linear ethylene polymers especially by a process wherein the grafting is done in a twin-screw, co-rotating extruder with the maleic acid or maleic anhydride being injected into a pressured zone of the extruder. The acid containing grafted linear ethylene polymer or polymer blends are dyeable in contradistinction to ungrafted linear ethylene polymers.

Title: Thermally stable dense electrically conductive diamond compacts
Inventor: BOVENKERK HAROLD P
IPC: C30B29/04
Filed: 1992-09-09
Abstract: THERMALLY STABLE DENSE ELECTRICALLY  CONDUCTIVE DIAMOND COMPACTS                ABSTRACT OF THE DISCLOSURE Broadly, the present invention is directed to a method for making a thermally stable, dense, electrically conductive diamond compact. The method comprises infiltrating a mass of diamond crystals with a silicon infiltrant in the presence of boron under conditions comprising a temperature of not substantially above 1200°C and a pressure of not substantially above 45 Kbars. The resulting compact contains diamond-to-diamond bonding. The boron can be provided in the form of boron-doped diamond. Alternatively, a boron-silicon alloy can be used for infiltrating boron-doped or undoped diamond. Further, boron can be added as elemental boron or B4C with silicon for infiltration. Alternatively, boron metal catalyst plus silicon infiltration can be used for boron-doped or undoped diamond. Combinations of these techniques also can be used. In the HP/HTprocess, the silicon infiltrates the diamond powder mass forming a network composed of silicon carbide by reaction of the silicon with diamond-carbon. The reaction leaves a sintered body composed of boron-doped diamond or boron compounds with diamond or a network of silicon carbide and silicon.

Title: Crystallizer filter
Inventor: COIN RICHARD
IPC: B01D9/00
Filed: 1992-11-05
Abstract: CRYSTALLIZER FILTER                          Abstract The present invention resides in an improved method and apparatus for the crystallization and filtration of a crystallizable material from a solution in which the crystallizable material is dissolved.  The solution is supersaturated with the crystallizable material.  The solution is fed through a filter having a layer of seed material thereon.  The depth of the layer of seed material and the rate of flow of solution through the seed layer allow the crystallization of the crystallizable material to take place within the layer of seed material.  The crystallization is allowed to proceed until a bed of crystals of the crystallizable material is formed on the filter surface.  A preferred filter material is a thin, flexible, polymeric material which is essentially two-dimensional.  The filter is back-flushed removing the bed of the crystallizable material from the filter surface.          Enough crystals remain on the filter surface to function as a seed layer for the formation of a new bed of crystals of the crystallizable material with the flow of additional solution through the filter.

Title: Amorphous adsorbent-based refining methods
Inventor: ESTES JENNIFER A
IPC: B01D15/00
Filed: 1993-03-22
Abstract: Abstract of the Invention The invention improves on the amorphous adsorbent-based processes by overcoming the soap leaching problem without using filtration before vacuum bleaching.  For fatty materials containing only minor amounts of phospholipid and trace metal impurities, simply vacuum drying at least a portion of the soap-containing fatty material prior to contacting with the amorphous adsorbent eliminates the soap leaching problem.  For fatty materials containing higher amounts of phospholipid and trace metals, simply using an acid pretreatment and the vacuum drying step eliminate the soap leaching problem.
