Title: Process for producing clean distillate pitch and/or mesophase pitch for use in the production of carbon fibers
Inventor: ROMINE HUGH E
IPC: C10C3/06
Filed: 1990-01-12
Granted: 1999-09-21
Abstract: A clean pitch suitable for the manufacture of carbon artifacts is obtained by distilling from an aromatic feedstock a distillate material free from mesophase and mesophase forming resins.      The distillate is heated to obtain a heat soaked distillate free from mesophase but containing mesophase forming resins. The heat soaked distillate is further heated with inert gas sparging to convert it to mesophase pitch suitable for manufacturing carbon fibers. The heat soaked distillate also finds use as a binder or impregnation pitch.

Title: Method of depositing directly activated species onto a remotely located substrate
Inventor: PEEDIN LESTER R
IPC: C23C14/32
Filed: 1990-08-13
Granted: 1998-07-07
Abstract: A method of depositing high quality thin film at a high rate of deposition through the formation of a high flux of activated precursor species of a precursor deposition gas by employing a substantial pressure differential between the pressure adjacent the aperture in a conduit from which said precursor deposition gas is introduced into the interior of a vacuumized enclosure and the background pressure which exits in said enclosure.  As the precursor deposition gas is introduced into said enclosure, a high density plume of said activated precursor species are formed therefrom due to an electromagnetic field established in an activation region adjacent said aperture.  The pressure differential is sufficient to cause those activated precursor species to be deposited upon a remotely positioned substrate.  In order to obtain a sufficient pressure differential, it is preferred that the flow of the precursor deposition gas reaches transonic velocity.  And in order to obtain a high quality thin film, it is preferred that the plume of activated precursor species is spaced from the substrate; without structural or electrical confinement, a distance from the activation region greater than the mean free path of undesired activated precursor species and within the mean free path of desired species.

Title: Method of reprocessing zinc- and lead-containing residues from metallurgical plants
Inventor: HIRSCH MARTIN
IPC: C22B7/02
Filed: 1990-12-20
Granted: 2002-02-12
Abstract: Zinc- and lead-containing residues from metallurgical plants are reprocessed by a thermal treatment in a circulating fluidized bed system. A major part of the heat demand is satisfied by a com-bustion of solid carbon in the fluidized bed reactor of the circulating fluidized bed system. A reducing fluidizing gas, which is virtually free of free oxygen, is fed to the lower part of the fluidized bed reactor, A solid carbon content from 5 to 30 % is adjusted in the fluidized bed in the lower portion of the fluid-ized bed reactor, which is supplied in its upper por-tion with oxygen-containing gases and in which CO2 is formed only at such a rate that zinc metal is not reoxidized. Substantially all solids are removed in a recycling cyclone from the suspension which bas been discharged and are recycled. The gas is cooled to a temperature at which zinc metal is oxidized to ZnO.      The dustlike zinc compounds and lead compounds are removed from the gas,

Abstract: A device for separation of air from fiber suspensions of flotation devices which are heavily air- and foam-lades or represent a mixture of fluid and foam features a hydrocyclone whose inlet opening is arranged least 2.5 m below the outlet opening of the flotation device for the air-laden fluid or mixture.  The separation section of the hydrocyclone is a slender, truncated cone-shaped body on whose pointed (thin) end the deaerated fluid is withdrawn.  In this outlet opening there is a back pressure maintained, so that the inlet opening is not completely covered by the vortex of the fluid, leaving still a sufficiently free entrance cross section for the foam.  Above the entrance section of the hydrocyclone a mechanical foam eliminator with a rotor is arranged, the rotor comprising an impeller wheel which is provided with radial blades.  A funnel-shaped suction sooket feeds the foam-air mixture to the impeller wheel.

Title: Sub-micron device fabrication
Inventor: WHITE DONALD LAWRENCE
IPC: G03F1/28
Filed: 1992-02-21
Granted: 1998-09-22
Abstract: Expedient fabrication of phase masks providing for many values of phase delay for exiting pattern delineating radiation depends upon a two-step procedure. Such masks offer improvement in ultimate device fabrication relative to that offered by prior binary-valued masks. In the first step, which may be carried out coincident with introduction of device feature information, apertures of appropriate size and distribution are produced in the relevant mask layer; in the second step material surrounding such apertures is heated to result in backflow-filling. Theconsequential layer thinning is such as to introduce the desired local change in phase delay.

Granted: 2001-12-25
Abstract: New stable, concentrated aqueous solutions of tetra-hydro iso-alpha acid (THIA) and hexahydro iso-alpha acid (HHIA) are disclosed. These solutions depend upon the presence of a second kind of iso-alpha acid to increase the solubility of both iso-alpha acids to a point outside of the ranges of their normal solubilities... in the case of THIA and HHIA, to a point above their solubility ranges and, in the case of unreduced iso-alpha acid (UIA) and dihydro iso-alpha acid (DHIA), to a point below their commercial prior-art solubility ranges. This "inversion" of solubility and stability behavior in water, which requires the presence of two different kinds of iso-alpha acids, is new to the art, and provides a novel approach for making commercially- desirable concentrates of THIA and HHIA available to the brewer.
