Abstract: An improved method for fastening thermoplastic bristle tufts (40) to a thermoplastic bristle carrier (4). The bristle carrier (4) includes premolded holes (5) with outwardly extending generally concentric collars (6) to receive the bristle tufts (40). The bristles (41) in each of the tufts (40) to be secured to the carrier (4) have their fastening ends melted and fused together to form a thickened fastening end portion (42). The thickened fastening end portion (42) of each tuft (40) has a cross-section which is no greater than the corresponding cross-section of the premolded hole (5) and outwardly extending collar (6) on the carrier (4). The premolded collars (6) and the adjacent side wall portions (8) of the premolded holes (5) in the carrier (4) are softened by non-contact heating means, the thickened fastening end portions (42) of the bristle tufts (40) are inserted into the premolded holes (5) and their associated collars (6) substantially without interference therebetween, and the softened collars (6) are swaged about the thickened fastening end portions (42) of the bristle tufts (40), thereby securing the bristle tufts (40) to the carrier (4) when the swaged collars (6) cool and harden. Because the collars (6) comprise only a small amount of thermoplastic material, heating and cooling requirements to effect joinder are minimized, thereby reducing the overall cycle time for the present process. In addition, the small amount of logicalized heating in the collars (6) avoids unsightly damage to or distortion of the carrier (4).

Title: Partial oxidation process for producing a stream of hot purified gas
Inventor: LEININGER THOMAS F
IPC: C10J3/54
Filed: 1994-05-20
Abstract: A partial oxidation process for the production of a stream of hot clean gas substantially free from particulate matter, ammonia, alkali metal compounds, halides and sulfur-containing gas for use as synthesis gas, reducing gas, or fuel gas. A hydrocarbonaceous fuel comprising a solid carbonaceous fuel with or without liquid hydrocarbonaceous fuel or gaseous hydrocarbon fuel, wherein said hydrocarbonaceous fuel contains halides, alkali metal compounds, sulfur, nitrogen and inorganic ash containing components, is reacted in a gasifier by partial oxidation to produce a hot raw gas stream comprising H2, CO, CO2, H2O, CH4 NH3, HCl, HF, H2S, COS, N2, Ar, particulate matter, vapor phase alkali metal compounds, and molten slag. The hot raw gas stream from the gasifier is split into two streams which are separately deslagged, cleaned and recombined. Ammonia in the gas mixture is catalytically disproportionated into N2 and H2. The ammonia-free gas stream is then cooled and halides in the gas stream are reacted with a supplementary alkali metal compound to remove HCl and HF.      Alkali metal halides, vaporized alkali metal compounds and residual fine particulate matter are removed from the gas stream by further cooling and filtering. The sulfur-containing gases in the process gas stream are then reacted at high temperature with a regenerable sulfur-reactive mixed metal oxide sulfur sorbent material to produce a sulfided sorbent material which is then separated from the hot clean purified gas stream having a temperature of at least 1000°F.

Abstract: ABSTRACT OF THE DISCLOSURE Leak-detection system and method for detecting a leaking  container.    The  system  includes  an  enclosure defining a cavity therein surrounding the container, which container may be a nuclear fuel rod having fission products leaking through a breach in the exterior surface of the fuel rod.  The fission products are capable of adhering to the exterior surface of the fuel rod as the fission prod-ucts leak through the breach in the fuel rod.  A radiation detector is in communication with the cavity for detecting the fission products leaking through the breach.  Moreover, a gas injector is in communication with the cavity for injecting a multiplicity of carrier gas bubbles into the cavity to remove any fission products adhering to the exterior surface of the fuel rod and to carry the fission products removed thereby to the radiation detector.   In this manner,  the detector detects the leaking  fission products even though they may tend to adhere to the exteri-or surface of the fuel rod.  In addition, an elevator is connected to the fuel assembly for elevating the fuel assembly in the cavity,  so that the external pressure acting against the exterior surface of the fuel rods is reduced in order to relieve the internal pressure in the fuel rods.  As the fuel assembly is elevated, any fission products tending to "hide-out" in the fuel rods expand and migrate through the breach.  As the  fission products migrate through the breach, they are carried by the carrier gas bubbles to the radiation detector where they are detected by the radiation detector.    In this manner, otherwise undetectable leaking fuel rods become detectable.

Title: Conversion of doped polycrystalline material to single crystal material
Inventor: SCOTT CURTIS E
IPC: C30B1/02
Filed: 1995-01-26
Abstract: A solid state method of converting a polycrystalline ceramic body to a single crystal body includes the steps of doping the polycrystalline ceramic material with a conversion-enhancing dopant and then heating the polycrystalline body at a selected temperature for a selected time sufficient to convert the polycrystalline body to a single crystal. The selected temperature is less than the melting temperature of the polycrystalline material and greater than about one-half the melting temperature of the material. In the conversion of polycrystalline alumina to single crystal alumina (sapphire), examples of conversion-enhancing dopants include cations having a +3 valence, such as chromium, gallium, and titanium. The polycrystalline body further can be inhomogeneously doped to form a first portion of the polycrystalline body that is doped to the selected level of the conversion-enhancing dopant and a second portion that is not doped such that heating the doped polycrystalline body causes conversion of first portion to a single crystal structure and the second portion retains a polycrystalline structure.
