Title: Separation of pollutants in the incineration of municipal solid waste
Inventor: NEWBY RICHARD A
IPC: F23G/
Filed: 1992-05-19
Abstract: 56,682 ABSTRACT OF THE DISCLOSURE Incineration of municipal solid waste (MSW) produces pollutants including hydrochloric acid, hydro-fluoric acid, sulfur compounds particularly sulfur oxides, nitrogen oxides, carbon monoxide and flyash.  Disposal of MSW by incineration is not acceptable unless these pollu-tants are eliminated or reduced to a very small fraction. There is disclosed a method of processing the products of combustion of the incineration of MSW in whose practice the products of combustion are passed through a fluid-bed filter contactor including ceramic candle filters.  The products of combustion are reacted with sorbents either in the contactor or in the channel through which the products are passed to the contactor to convert the acids and the sulfur compounds into solid particulate and reacted with reactants in the presence of catalysts in the contactor to decompose the nitrogen oxides into atmospheric gases.  The particulate is filtered out by the filters and deposited as ash together with the flyash which is also filtered out. The carbon monoxide is oxidized by the air in the contactor to carbon dioxide.  The atmospheric gases are vented to the atmosphere together with the filtered products of com-bustion.

Title: Conductive fabric and method of producing same
Inventor: JOBE ANTHONY
IPC: D06M101/16
Filed: 1992-06-05
Abstract: CONDUCTIVE MELTBLOWN MATERIAL AND     METHOD OF PRODUCING SAME          Abstract of the Disclosure Conductive meltblown fabrics are disclosed which have improved strength and hand over conventional conductive meltblown fabrics. Also disclosed is a process for spraying a solution containing a conductive agent into a molten stream of meltblown fibers before they are deposited onto a forming wire. By applying the solution onto the fibers before they are deposited onto the forming wire, the heat of the molten stream vaporizes the solvent carrying the conductive agent and thereby eliminates the need to subsequently dry the formed material. By eliminating the drying step, degredation of the strength and hardening of the hand of the material normally resulting from the wetting and drying of meltblown fabrics is avoided. There is also disclosed a conductive SMS laminate having a conductive meltblown layer sandwiched between two untreated and nonconductive spunbond layers.

Abstract: L'invention se rapporte à un procédé et à un dispositif servant à contrôler et à surveiller les votes majoritaires dans un sélecteur temporel numérique et à plans multiples, chacun des trois plans au moins (A, B, C) fonctionnant en parallèle, étant équipé de façon identique. Un flux de données d'entrée est réparti entre les plans et est admis à traverser l'équipement contenu dans chacun de ces plans pour générer des flux de données de sortie. Ces flux de données de sortie sont comparés les uns aux autres et un flux de données de sortie de vote majoritaire se basant sur la comparaison, est produit par le système. On introduit périodiquement une erreur correspondant à un schéma prédéterminé dans les trois plans et on compare les flux de données reçus et le flux de données de vote majoritaire. Si on trouve une erreur dans l'un des flux de données, une alarme est émise. Si une alarme (LARM1) est censée avoir été provoquée par une erreur introduite en fonction du schémaprédéterminé, celle-ci est identifiée en se basant sur la connaissance du schéma prédéterminé afin de la distinguer des alarmes résultant d'erreurs qui n'ont pas été introduites selon le schéma.

Patent CA-2088183-A1 (CA)
Inventor: NOE OSKAR
IPC: B21B15/00
Filed: 1993-01-27
Abstract: A strip is displaced longitudinally with its edges parallel to a stationary machine centerline at a predetermined travel speed through a monitoring station and through a trimming station spaced downstream from the monitoring station and equipped with a pair of transversely offset trimming heads.  The transverse offset of the strip edges relative to the machine centerline is continuously monitored at the monitoring station and respective outputs corresponding to the transverse offsets between the respective edges and the machine centerline at the monitoring station are produced.  The time the strip takes to travel from the monitoring station to the trimming station is calculated based on the strip travel speed and the longitudinal spacing between the stations.  The trimming heads are transversely displaced in accordance with the calculated time and the respective transverse edge offset such that the heads remain in contact with the strip.  Continuous edge portions are thus cut from the strip with the heads.

Abstract: A stearate-matrix, pre-spotter composition in solid stick form to be applied by direct contact to stained areas of fabric, thereby transferring the composition to the stained areas of the fabric.  The composition includes an alkyl aromatic sulfonic acid and/or sulfonate, at least one nonionic surfactant, and an enzyme uniformly dispersed throughout a semi-hard stearate matrix.  By the addition of sodium bicarbonate, the composition optimizes the pH to promote enzyme action, while simultaneously achieving a satisfactory drop point for shipping and warehousing.  At pH levels from 8.2 to 9.0, acceptable hardness and transferability are still achieved, which was previously thought not to be possible without the addition of a critical amount of certain salts.

Title: P-N Junction Devices with Group IV Element-Doped Group III-V Compound Semiconductors
Inventor: KOPF ROSE F
IPC: H01L29/812
Filed: 1993-07-14
Abstract: This invention embodies p-n junction devices comprising Group III-V compound semiconductors in which the p or n or both p and n regions are formed by a superlattice selectively doped with an amphoteric Group IV element dopant selected from carbon, germanium and silicone. The superlattice includes a plurality of periods, each including two layers. Depending on the conductivity type, only one of the layers in the periods forming the superlattice region of said type of conductivity is selectively doped with said dopant, leaving the other layer in these periods undoped. The superlattice is formed by Molecular Beam Epitaxy technique,and the dopant is incorporated into respective layers by delta-doping as in a sheet centrally deposited between monolayers forming the respective layers of the period. Each period includes 5 to 15 monolayers deposited in the two layers in a numerical ratio corresponding to a cation compositional ratio in the compound semiconductor. Low growth temperatures, e.g. ranging from 410 to 450°C lead to mirror-like surfaces. For a compound semiconductor Ga0.47In0.53As, the GaAs/InAs ordered superlattices with eight monolayers per period are grown in a ratio of 0.47/0.53. At free carrier concentrations of 1016cm-3, carrier mobilities of 200 and 2300 cm2 /Vs for p-type and n-type are obtained with carbon as the amphoteric dopant.
