Abstract: Abstract of the Disclosure A controlled gas environment is provided against a surface area of a semiconductor wafer for performing processes on the area in the fabrication of integrated circuits thereon, including processes of deposition, impurity implantation, etching, ablation, and other radiation induced chemical processes involving the gas atmosphere by maintaining a continuous gas flow over the area and a portion of the surrounding area of the wafer surface covered by an enclosure that is suspended on the surface on a film of the flowing gas, the pressure, temperature and composition of the gas atmosphere against the surface area being controlled to meet the requirements of each processing step and/or to carry away particles while the gas seal is maintained.  In a particular embodiment, intense ultraviolet (UV) laser radiation is focused by an optical system on a target on the semiconductor wafer surface through the suspended enclosure while the wafer is held on a table that moves in the plane of the wafer surface in order to expose different selected areas of the surface to the combined effects of the UV radiation and the gas atmosphere.

Title: Spiral wound filter element
Inventor: BAYERLEIN RICHARD E
IPC: B01D27/06
Filed: 1988-01-19
Granted: 1992-06-23
Abstract: ABSTRACT OF THE DISCLOSURE     A filter element is formed by spirally winding at least two layers of filter material about a central, per-forate supporting core.   The layers include a relatively fine porous filter material and a relatively coarse porous filter material.   The layers may be formed from blankets of material,  or one or both layers may be pleated.  The fine filter material extends beyond the edges of the coarse filter material to overlie and close the longitudinal ends of the layers of the coarse material.  Fluid to be filtered passes radially through the element until  it encounters a clogged or plugged area.   The fluid will then take a circumferential spiral route until it again finds an open area of the filter and can pass radially toward the core.

Abstract: ABSTRACT OF THE DISCLOSURE          This publication discloses a method and an apparatus for the utilization of the heat value of a water-bearing fuel in a gas turbine power plant. The apparatus comprises a high-pressure combustion unit (7), a gas turbine (15), a generator (16), and heat recovery units, the latter connected the system close to the gas turbine (15) outlet. According to the invention the water-bearing fuel is dried in a high pressure by the heat energy of the turbine exhaust gases, and the steam generated in the dryer stage is fed to the high-pressure section of the combustion process, at a point between a compressor (9) and the turbine (15), that is, for instance, into the combustion or gasification unit (7). The system in accordance with the invention provides for the utilization of the heat value of fuels having a high moisture content.

Abstract: ABSTRACT OF THE DISCLOSURE:               In the described process of simultaneously removing nitrogen oxides and sulfur dioxide from an oxygen-containing exhaust gas, the exhaust gas is mixed with NH3 and is then supplied as a fluidizing gas to a fluidized bed, which consists of a catalyst for effecting a reduction of NO with NH3 to form N2 and an oxidation of SO2 with O2 to form SO3. The catalyst consists of a carrier and of catalytically active substances consisting of V205 and of Fe203, FeSO4 and/or Fe2(SO4)3, and alkali sulfates. The SO3 formed by oxidation may be recovered as sulfuric acid or may be combined with a desulfurizing agent, which consists of Na2CO3, MgO, MgCO3, CaO, CaCO3 and/or Ca(OH2).

Title: Mass polling system
Inventor: WALKER ROBERT W
IPC: H04M3/46
Filed: 1988-02-23
Granted: 1991-03-19
Abstract: ABSTRACT OF THE DISCLOSURE           A mass polling system is situated in a central office of a telephone system, and does not employ toll machines or trunk lines leading to toll machines.  The mass polling system ensures that a charge record is generated before the beginning of a recorded announce-ment, during the period while the caller is receiving an audible ring signal.  Preferably, the charge record is generated at the initiation of the audible ring signal.  In this way billing errors due to early caller disconnect are reduced or eliminated.  The mass polling system is responsive to a billing disable command which prevents the mass polling system from causing charge records to be generated when the mass polling system is out of service.

Granted: 1992-06-23
Abstract: Abstract of the Disclosure FLUID BED REACTOR AND PROCESS     Undesirable conversion of a silicon source, such as silane, in the freeboard above a fluidized bed of silicon particles in a fluidized bed reactor, can be reduced by cooling the gas within the freeboard.  Preferably, the reduction in temperature is achieved by introducing into the freeboard a stream of relatively cool quench gas such as hydrogen, which also reduces the concentration of silane in the freeboard.  As a result of these two factors, the invention improves the service factor of the fluidized bed apparatus and reduces the amount of silane conversion to undesired by-products.

Abstract: A method of manufacturing a  portion of a seat is  disclosed.    A cover member is shaped to a predetermined shape and placed in  a foam molding  tool into  which is  injected an  expandable  liquid foaming material to mold a foam pad which is integrally bonded  to the cover member.  In the  manufacturing of seat backs, the  cover member consists  of  a  tubular envelope  cover positioned  on  a cantilever forming tool.  Once the  foam pad is molded, the  cover member is turned inside out to enclose the foam pad with the cover member.   The  cover  is  then  telescoped  over  a  seat   frame.          Alternatively, the  foam pad  can  be molded  to a  shaped  fabric sheet, the envelope cover formed  by sewing a second cover  member to the fabric sheet.   A seat cushion is  made by shaping a  cover member, placing the cover member in a foam molding tool which also holds the seat  frame and injecting  an expandable liquid  foaming material into the mold to mold the foam cushion, bond the  cushion to the cover and embed the seat  frame in the foam.  The edges  of the cover are  then wrapped around  the side of  the foam pad  and attached to the frame.  Alternatively, a side panel can be sewn to the cover and attached to the frame.
