Title: Method and apparatus for purifying gaseous fluids
Inventor: GUTERMUTH PAUL SR
IPC: B01D46/04
Filed: 1994-03-21
Abstract: Abstract The invention relates to a method and an apparatus for purifying gaseous fluids by separating the media such as  oils  present  therein  and  contaminant  particles present  therein.   To  permit  on  the   one   hand problem-free cleaning of the separator area (14, 16, 18,  20)  and on the other hand an increase in the separating degree,  it is proposed that the gaseous fluid to be purified is cooled and/or that a gas or fluid  is  sprayed  into the  fluid before  it  passes through the separator area (14, 16, 18, 20).
Patent CA-2122214-A1 (CA)
Title: Reinforced concrete tiles and methods of making same
Inventor: THOMAS JOHN F
IPC: B28B7/34
Filed: 1994-04-26
Abstract: Abstract of the Disclosure A reinforced concrete tile is provided with substantially increased tensile strength and lightness in weight by a lightweight substrate layer of reinforced resinous material which has been applied while wet to the lower surface of a layer of concrete so as to integrally bond itself to the layer of concrete.  The substrate layer may comprise a resinous mixture reinforced with fibers or with a mesh of fiberglass or other appropriate composition.  In a first method of making reinforced concrete tiles, a concrete tile which has been formed has the bottom surface thereof treated such as by sandblasting so as to roughen the surface and remove any loose debris therefrom.  A layer of reinforced resinous material is then applied to the bottom surface of the concrete tile.  In a second method of making a reinforced concrete tile, wet concrete is extruded onto a pallet having an upper surface, which may be formed by a liner of appropriate configuration to impart a wood shingle appearance, and which defines the top surface of a tile to be formed.  After shaping the wet concrete tile on the pallet, a layer of reinforced resinous material is applied to the surface of the wet concrete tile opposite the pallet, so as to form a reinforced substrate layer on the base of the concrete tile being formed, before curing and removing the tile.  The layer of reinforced resinous material may be applied by application of layers of resinous slurry before and after application of a layer of mesh, or by pressing the mesh into a layer of slurry using a roller. The layer of mesh can be offset to form the base of a molded side lock portion of the tile and to help secure the tile to an underlying roof structure.  In accordance with still further methods, reinforced tiles are formed by disposing a layer of mesh between concrete layers of different thickness and by placing a layer of mesh on the upstanding pegs of a pallet and forming the concrete tile thereover.

Filed: 1994-05-27
Abstract: A process for the direct production of sponge iron particles and liquid pig iron from lump iron ore is described, in which the iron ore is reduced as a loose bed in a direct reduction unit by means of hot reducing gases to sponge iron and is subsequently melted in a melting gasifier by means of the introduced carbon and blown in oxygen-containing gas, accompanied by the production of reducing gas.  At least part of the reducing gas, after cooling to the temperature necessary for reduction, is introduced into the reduction zone of the direct reduction unit.  A considerable part of the carbon and reducing gas is provided by a mixture of hydrocarbon-containing plastic and petroleum coke and/or coke (fines).  The reducing gases are primarily at least partly obtained by cracking from the plastic and by thermal gasification from the coke.

Abstract: COMMUNICATIONS SYSTEM FOR THE GAME OF FOOTBALL     ABSTRACT OF THE DISCLOSURE A navel communications system for the game of football allows the quarte-r back to be heard by his teammates over crowd noise.  The communications system comprises a plurality of loudspeakers positioned on opposite sidelines of the playing field in the approach to the goal lines at each end of the field, preferable between the 10 and 20 yard lines. The speakers are aimed or focused at ground level toward the players for selective use whenever the crowd noise is excessive as the team is approaching the goal line. A receiver and amplifier and appropriate circuits are associated with the speakers a small microphone, transmitter and switch are car-ried by the quarterback, preferably on his helmet and the safety padding, i.e., shoulder pads. The quarterback may selectively operate the switch whenever the crowd noise becomes excessive to activate the transmitting and receiving equipment to his call of the plays to be transmitted from the microphone to the speakers which direct the calls along the surface to be heard by his teammates. The system is activated only for a short time, on demand by the quarterback, to allow his call of the plans to be heard by the team. The quaterback's calls emitted by the speakers are heard mainly at the level of the playing field and do not interfere with the fans enjoyment of the game.

Title: Process for dividing the sulphide content of the green liquor for the production of white liquors having high and low sulphidity
Inventor: PETTERSSON BERTIL
IPC: D21C11/00
Filed: 1993-09-29
Abstract: The invention relates to a process for dividing up the sulphide content of green liquor into a sulphide-rich part and a sul-phide-poor part by crystallizing out sodium carbonate (Na2CO3). The crystallization of the sodium carbonate is effected by evaporating green liquor with a ratio of hydroxide ions [OH-] and sulphide ions [HS-] such that the liquor which is obtained after evaporation and separation of the solid phase has high sulphidity and an acceptably low content of carbonate ions [CO32-]. Prior to evaporation, the hydroxide ion content in the liquor is increased by adding quicklime (CaO). The solid phase (sodium carbonate and calcium carbonate) which has been separated off is diluted with water so that the sodium carbonate crystals go into solution and at the same time the solution is given a cation content which favours the causticiza-tion which is subsequently undertaken. The causticization is carried out in a conventional causticization plant. After separat-ing off the lime sludge (CaCO3) which is formed during the causticization processes, a white liquor of low sulphidity and low carbonate content is obtained for use in the cooking process and, after oxidation, also in the oxygen gas delignification prior to final bleaching of the pulp.
