Patent number: 4083774Abstract: After an initial separation of paper, plastics and the light fibrous types of materials, as well as magnetically removable ferrous metals, from refuse material, the remaining mixed solid materials are projected outwardly in a generally horizontal path and subjected to a "flight-path" type of segregation where a magnetic field is used to influence and lessen the length of the trajectory of the conductive metals in the mixture of materials. The magnetic field induces a retarding force related to the size, conductivity and to some extent to the shape of the fragments which, in combination with the force of gravity, modifies the trajectory of different materials. As a result, fragments of different types of materials will tend to "drop out" at different distances along the general flight path according to their individual electrical conductivity properties.Type: GrantFiled: February 3, 1976Date of Patent: April 11, 1978Assignee: UOP Inc.Inventor: Jack A. Hunter

Patent number: 4070278Abstract: After an initial separation of paper, plastics and the light fibrous types of materials, as well as magnetically removable ferrous metals, from refuse material, it is subjected to a "time-of-flight" type of segregation where a magnetic field is used to influence the downward free-fall of the remaining mixed solids materials. In combining a magnetic field with gravity fall, there is a retarding force on each conductive piece of material which is related to its conductivity and volume. As a result, different types of material fragments of about the same size will have different descent times in the drop zone which will depend primarily upon density and electrical conductivity and a rotatable diverter means, which is properly timed and synchronized in its movement with respect to the releases of unsegregated material, can provide for the deflection of the different types of materials into appropriate collecting zones.Type: GrantFiled: February 3, 1976Date of Patent: January 24, 1978Assignee: UOP Inc.Inventor: Jack A. Hunter

Patent number: 4047895Abstract: A catalytic converter system for engine exhaust gases provides an auxiliary moving bed of SO.sub.2 adsorption material such that the SO.sub.2 content of the exhaust stream can be continuously adsorbed into a segmental portion of the bed prior to reaching the catalytic conversion zone. At the same time, the higher temperature treated gases from the catalyst zone are continuously passed through another portion of the SO.sub.2 adsorption material to effect the removal of sorbed SO.sub.2 therefrom, and the energy of the exhaust gas stream flow is utilized to contact vanes or turbine type blades to provide the continuous rotational movement of the bed of SO.sub.2 adsorbing material so that it, in turn, is rotated or cycled through the adsorption zone and through the desorption zone and then back to the adsorption zone in a continuous operation as long as there is exhaust gas flow in the system.Type: GrantFiled: October 30, 1975Date of Patent: September 13, 1977Assignee: UOP Inc.Inventor: Peter Urban

Patent number: 4023928Abstract: An electric lamp bulb or electric resistance coil is provided to radiate heat to one or more adjacent surfaces which have an active oxidation catalyst such that fumes and odors in the confines of a room that are drawn over the catalytic surface will be converted to less objectionable products. A catalytic device with an incandescent light bulb type of heating element is of particular advantage in that it can readily be screwed into a lamp base or mounted in other forms of current supplying receptacles and, in addition to a light source, will provide a heat emitting surface for heating the catalyst surface and inducing natural air convection current flow past the catalytic surface. Also, a fume control device which utilizes a resistance heating coil can readily provide both radiant heat and convection heat so that there will be the dual function of fume oxidation from air flow past a heated catalyst surface and radiant heat into a room area.Type: GrantFiled: September 19, 1975Date of Patent: May 17, 1977Assignee: UOP Inc.Inventor: Vladimir Haensel
