Title: Method of treating flue gases and combustion residues
Inventor: ZECHNER FRANZ
IPC: B01D53/64
Filed: 1988-08-18
Granted: 1992-09-29
Abstract: ABSTRACT OF THE INVENTION                A METHOD OF TREATING FLUE GASES AND       COMBUSTION RESIDUES     The alkalinity of the solids, slag and ash, which occur in a combustion plant such as an incinerator is utilized for the flue gas scrubber, whilst at the same time the storability and the alkaline flue gas washing stage are improved.  For this purpose, the scrubbing liquor is removed from the tank of a flue gas scrubber for SO2, so that it can be used for the separate scrubbing of slag and ash in, for example, stirrer vessels. Subsequently, the slag is separated in a sieve according to particle size, and the fine portion, together with the ash, is supplied to a dewatering stage, from which they pass to a stirrer vessel, in order to be re-washed there with scrubbing liquor from tank emanating from a flue gas scrubber for HCl.  In a subsequent washing stage, the solids are freed of chlorides.  The scrubbing liquor from the dewatering stage is returned to the tank, while the scrubbing liquor from the settling tank is returned to another tank.  To separate mercury and the other heavy metals, additional stages are provided.

Abstract: ABSTRACT An emergency vent for use on a tank for storing or transporting fuel or the like has a housing with a cover thereon.  The housing has an upper portion and a lower portion with a screw thread on the outer surface of the lower portion for affixing the vent to a tank opening.  Alternatively, the lower portion can have a plain end for welding to the tank. The upper portion has a larger diameter than the lower portion and contains a support having a passageway with a bolt extending through the passageway and being connected to the cover.  The bolt has a head which is too large to pass through the passageway.  The cover has a circular groove on an inner surface thereof, the groove being sized so that a top edge of the housing fits within the groove when the cover is in a closed position.  The bolt limits the distance that the cover can be raised above the housing.  In a variation of the vent, the groove contains a gasket and there is a spring located on the bolt between the support and the head, the spring exerting a force to hold the cover on the housing.  A disc that is concave upward can be mounted on the bolt between the cover and the support to make pilferage more difficult.  Previous emergency vents do not reduce the chances of pilferage or they are continuously open resulting in the loss of fuel vapours or they do not prevent dirt or other contaminants from entering the tank.

Abstract: ABSTRACT OF THE DISCLOSURE A method of forming a gasket with an accurately aligned and deposited sealing bead and embossment arrangement.  The method comprises providing a deformable gasket body having two spaced apart major surfaces.  The next step involves applying a relatively incompressible sealing material against one of the major surfaces on the gasket body with sufficient pressure and in a manner deforming both of the major surfaces of the gasket body.  The deformation of the gasket body defines an embossment comprising a projection extending outwardly from one major surface and a substantially corresponding indentation extending inwardly from the other major surface.  Besides creating an embossment, sealing material remains in and fills the indentation to provide support for the embossment.  Another step in the process involves curing the sealing material filling the indentation in the gasket body.

Abstract: ABSTRACT         There is described retroreflective material comprising a transparent surface layer having a front side and a back side and an array of cube-corner reflective elements, each of the reflecting elements including:  a rectangular base on the back side of the surface layer; two rectangular faces approximately perpendicular to each other, each one being joined to an edge of the rectangular base to form a reflecting element having a triangular cross section; and two triangular faces that are approximately parallel to each other and approximately perpend-icular to the rectangular faces, and forming the ends of the reflecting elements.  The triangular and the rectangular faces define a pair of cube-corners therebetween; the reflecting elements being formed by two approximately perpendicular sets of parallel grooves, a first set of V-shaped grooves, and a second set of grooves having a pair of faces nearly perpendicular to the rectangular base.  At lease one of the sets of grooves includes more than one groove having a groove side angle that differs from another groove side angle of the same set by a small amount less than 3°.  The array of cube-corner retroreflective elements is characterized by small variations in at least one of the dihedral angles between the faces from one reflecting element to another, the variations existing in at least some but not necessarily all of the reflecting elements.

Abstract: Abstract In a multiprocessor system, the processors are interconnected by a non-blocking communication medium such as a crossbar switch. Each processor is connected to a dedicated port circuit at the switch by an optical link. Each port circuit is connected to the crossbar switch by an electrical link. The port circuits are interconnected by a contention medium. A port circuit sends an access request by its connected processor to the destination processor over the contention medium. Circuitry at each port circuit receives requests, for access to the connected processor, prioritizes conflicting requests, and grants them sequentially. The circuitry interleaves grants of access to the connected processor with grants of outgoing access requests made by the connected processor. The circuitry grants an access request by causing the crossbar switch to establish the corresponding connection.

Granted: 1993-04-20
Abstract: ABSTRACT     An improved polarized electromagnetic relay comprises a base of magnetic material mounting thereon a contact assembly and an electromagnet with an armature which is pivotally supported at its end to the base and operatively connected to said contact assembly for opening and closing a relay contact.  Included in the electromagnet is a pair of first and second pole members which are magnetized to opposite polarity by a permanent magnet coupled thereto and which define therebetween a magnetic gap into which the other end of the armature extends.  The first pole member and the armature are magnetically coupled to the base so as to cause a magnet flux of the permanent magnet to circulate through the second pole member, the armature, the base, and the first pole member for attracting the armature to the second pole member.  Upon energization of the coil, a resulting coil flux circulates through the armature, the base, and the first pole member in opposing direction to the magnet flux for attracting the armature to the first pole member.  A cover of magnetic material is included to fit over the base and be magnetically coupled thereto.  The second pole member is disposed adjacent to the inner wall of the cover so as to define therebetween an air gap which is cooperative with the second pole member, the armature, base, and the cover in order to circulate an additional coil flux in the opposing direction to the magnet flux across the second pole member and the armature upon energization of the coil, weakening the magnetic flux and therefore expediting the armature movement by the coil flux to thereby improve response sensitivity.

Abstract: In a computer implemented system for composing lines of text the spacing between each adjacent pair of characters is uniquely determined by processing, in accordance with a pregiven program, a number of digital "space" values related to the shapes of the facing sides of the involved characters. Starting with a uniform or near-uniform fundamental spacing between all adjacent pairs of characters the processing of the space values of a given pair of adjacent characters results in possible adjustments in this fundamental value to achieve a more aesthetically pleasing line of text. For each pair of adjacent characters the processing is a two-stage one with the first stage making an adjustment in the fundamental spacing if it is possible to overlap portions of the two characters and with the second stage making an adjustment which, aside from the possibility of overlapping, is dependent on the degree of openness or empty space present between the characters when fundamental spacing is used.
