Title: Scientific visualization system
Inventor: RAMANUJAM GOPALAN
IPC: G06T17/00
Filed: 1992-02-11
Abstract: A  3D  scientific  visualization  system  for viewing models composed of polyhedra or other elements having vertices at which analysis results (e.g., temperature or pressure) are defined.  The model is viewed either in a cutting plane or as a contour surface in which a given result assumes a specified value.  Polygons making up an intersection surface formed by the intersection of the cutting  plane  or  contour  surface  with  the  polyhedra forming the model are generated and passed to a polygon processor  for  rendering  and display  on  a  raster-scan device.  A series of intersection surfaces are generated for display by varying either the position of the cutting plane  along  its normal  or the value  that the  result assumes on the contour surface.  The testing of elements for possible intersection by the cutting plane or contour surface is speeded up by presorting the elements into zones, based upon either  the position of each element along the cutting plane normal or the value of the result over  the  vertices  of  the  element,  and  testing  only elements within certain zones for intersection with the plane or surface.   Intersection calculations for edges shared by multiple elements are minimized by maintaining a global list of edges and flagging those edges whose intersection point with the  cutting plane  or  contour surface has been calculated for any element of the model.          The  outer  surfaces  are  identified  for  viewing  in  an alternative mode of operation by counting the elements sharing a given face of the model and flagging as outer faces those faces associated with only a single element.

Title: Method for detection of alien matter contents in gases
Inventor: PUUMALAINEN PERTTI
IPC: G01N27/64
Filed: 1991-10-10
Abstract: The objective of the invention is a method for detection of alien matter contents in gas, in which method the gas and the substances contained in it are ionized in an ionization room (1). By the present methods impurities in gases cannot be determined fast and in small concentrations. In the method of the invention the ions contained in the gas are separated in a separation section (2) into positive and negative ions, of which at least the ions of either sign are led into a narrow analyzer channel (4). There, due to the capillary force, they are be forced to move in the middle section of the channel, from where they are deflected by electric fields of different strength caused by different voltages (U1-U10) into an electrode located at the edge of the channel, where they cause ion current (I1-I10). On the basis of the ion currents a current spectrum is made, on the basis of which different substances are detected and their concentrations determined with the aid of corresponding spectra obtained with standard samples of different substances.

Title: Catalytic converter having a metallic monolith mounted by a heat-insulating mat of refractory ceramic fibers
Inventor: LANGER ROGER L
IPC: F01N3/28
Filed: 1993-05-07
Abstract: A catalytic converter has a metallic monolith that is mounted in a canister by a heat-insulating mat of melt-formed refractory ceramic fibers that have been annealed to provide a Resiliency Value of at least 10 kPa. Previously known melt-blown fibers used in such mats were thought to require a fine-grained crystalline structure to have a higher resiliency value. However, a mat in accordance with the invention having a Resiliency Value of at least 10 does not take a compression set that would allow the monolith to become loose, is made from ceramic fibers which are preferably melt-formed from a mixture of about equal parts by weight of Al2O3 and SiO2.      After being annealed, the ceramic fibers can have a fine-grained crystalline structure, but significant energy savings can be realized by reducing the annealing temperatures and times such that the fibers have an amorphous structure while still attaining excellent Resiliency Values.
