Abstract: An apparatus for heat treating contaminated particulate material and more particularly, an appar-atus for reclaiming foundry sand.  The apparatus includes a heated, inclined rotary drum and an auger projects into the upstream end of the drum and serves to feed material to the drum.  The auger includes a spiral flight carried by a hollow shaft and a blower is connected to the outer end of the hollow shaft so that air is supplied through the shaft into the drum.  A seal is provided between the non-rotating auger housing and the drum, and the seal includes an annular bearing plate mounted on the end of the drum while a sealing ring is connected to the auger housing and is biased against the plate to provide a seal.  The excess air in the heated drum burns off the organic contaminates from the particulate material and calcines the mineral contaminates.  The treated particulate material is transferred from the downstream end of the drum to a second cooling drum and air is passed through the second drum countercurrently to movement of the particulate material to cool the material.

Abstract: Continuous manufacture of 1,1,1-chlorodifluoroethane from 1,1,1-trichloroethane and hydrofluoric acid by liquid phase reaction in the presence of at least one fluorination catalyst. According to the invention the operation is carried out at an absolute pressure of between 6 and 30 bars and at a temperature of between 50 and 120 DEG C, the catalyst content of the reaction mixture, expressed as weight percentage of metal, being between 0.05 and 10% and its content of organohalogen by-products outside 140 series being regulated at a value of less than 40% by weight. This process makes it possible simultaneously to obtain a high degree of conversion of hydrofluoric acid, to minimise the coproduction of 1,1,1-trifluoroethane and of organohalogen by-products, and to make it easier to recover the hydrochloric acid formed.

Abstract: In the method and apparatus of the present invention a file to be added to the database is given a unique name that is dependent upon the contents of the file such that, when the contents of the source file changes, the name of the database component file to be added to the database also changes. Conversely, if two files of the same name have the same information contained therein, the same file name will be generated and the duplication of information in the database is prevented by providing a simple test that checks for the existence of the name of the database file before the generation and addition of the new file to the database. If the file name exists in the database, the information is already contained in the database and the file is not generated and added to the database information. Preferably the name of the file is generated by computing a hash value from the contents of the file and concatenating the hash value to thename of the source file. Because the source file name is used in conjunction with the hash value to construct the database file name, the hash value does not haveto be unique for all files but only for those source files having the same name.

Abstract: Process for the improvement of the sulphur yield of an assembly which produces sulphur from from H2S and which consists of a sulphur plant (1), an oxidation and hydrolysis unit (2) and a purification unit (3). Said sulphur plant (1) in producing sulphur provides a residual gas (17b) which incorporates H2O, COS and/or CS2 and H2S and SO2 in a mol ratio of H2S:SO2  >/=  2:1. Said residual gas passes into the unit (2) on a H2S oxidation and COS and CS2 hydrolysis catalyst which functions between 180  DEG C and 700  DEG C, in the presence of air (47), thus producing a residual gas (38) free of COS and CS2 and incorporating H2S and SO2 in a mol ratio which is kept equal to 2:1 by regulating the air flow (47). The residual gas (38) is introduced into the purification unit (3), in which H2S and SO2 are made to react in order to produce sulphur and to obtain a purified residual gas (45).

Title: Treatment of automobile shredder residue by vacuum pyrolysis
Inventor: ROY CHRISTIAN
IPC: C10B57/02
Filed: 1991-06-21
Abstract: Metals  are  recovered  from  automobile  shredder residue  by  subjecting  the  shredder  residue  to  vacuum pyrolysis  to  produce  non-condensable  gases,  condensable hydrocarbon vapors and water vapor,  and a solid residue containing non-oxidized metals and a carbonaceous material.          The vacuum pyrolysis is carried out at a temperature in the range of about 425 to about 650°C, under a subatmospheric pressure in the range of about 50 to about 200 mmHg so as to thermally decompose and substantially completely vaporize organic matter adhered to the metals. At least one metal is separated from the solid residue, the metal being recovered in non-oxidized and substantially carbon-free form suitable for direct recycling. Significant amounts of valuable metals such  as  iron,  copper,  aluminum  and  zinc  may  thus  be recovered.

Abstract: ABSTRACT OF THE DISCLOSURE An  improvement  in  a  vertical screw  cutter/mixer consisting of an inverted generally conical container and a vertical screw.  The vertical screw is rotatably mounted within the container solely at its base.  The improvement consists of a combination of elements.  A spiral flight is provided  on  the  screw  consisting  of  a  plurality  of convolutions describing a truncated conical shape.  Means is provided for mounting a plurality of blades to the screw such that they extend upwardly past the apex of the shaft of the screw.  At least one of the blades is positioned adjacent a peripheral edge of an upper convolution of the flight  such that a circular path is described by the peripheral blade which is substantially the same diameter as the upper convolution of the flight.  Impaling fingers are positioned adjacent to the top of the container and extend inwardly. The impaling fingers are in substantially horizontal alignment with the upwardly extending blades. The  impaling fingers  are movable  between  an  extended position  and  a  retracted  position.    In  the  extended position the fingers impede the speed of rotation of the bale to less than the speed of rotation of the screw whereupon the blades tear chunks of material from the bale. In the retracted position the fingers release the bale whereupon the  hale  descends  upon by  force  of  gravity further into the container until obstructed by the upper convolution of the flight of the conical screw.
