Patent CA-2055714-A1 (CA)
Inventor: ALVES JAMES F
IPC: G06V10/426
Filed: 1991-11-15
Abstract: Image data is processed by a low level feature detection processor that extractslow level features from an image. This is accomplished by converting a matrix of im-age data into a matrix of orthogonalicons that symbolically represent the image scene using a predetermined set of attributes. The orthogonal icons serve as the basis of pro-cessing by means of a high level graph matching processor which employs symbolicscene segmentation, description, and recognition processing that is performed subse-quent to the low level feature detection. This processing generates attribute graphs rep-resentative of target objects present in the image scene. High level graph matching compares predetermined attributed reference graphs to the sensed graphs to produce a best common subgraph between the two based on the degree of similarity between the two graphs. The high level graph matching generates a recognition decision based on the value of the degree of similarity and a predetermined threshold. The output of the high level graph matching provides data from which a target aimpoint is determined, and this aimpoint is coupled as an input to a missile guidance system that tracks identi-fied targets.

Title: Fetal cell recovery method
Inventor: SIMONS MALCOLM J
IPC: C12N5/073
Filed: 1991-03-27
Abstract: The present invention provides a method for selectively recovering fetal cells from a maternal blood sample. The method is performed on a blood sample from a pregnant woman having different first and second cell surface antigens expressed by a first allele of a polymorphic genetic locus and a second allele of a polymorphic genetic locus. The method separates maternal and fetal cells based on differential reactivities of the cells to antibodies specific for polymorphic cell surface antigens, particularly the HLA antigens. In particular the fetal and maternal cells are separated based on the non-reactivity of the fetal cells to an antibody specific for a cell surface antigen encoded by a non-transmitted maternal allele. The method can be performed using solid phase-affixed antibody and recovering non-bound cells or using fluorescent labeled antibody and recovering unlabeled cells by fluocescence-activated cell sorting. In a preferred embodiment, the cells are also contacted with a second antibody specific for the second cell surface antigen. Fetal cells are separated based on their reaction with, at most, one of the antibodies.

Title: Method and apparatus for manufacturing and repairing molten metal containment vessels
Inventor: CONNORS CHARLES W JR
IPC: F27D3/00
Filed: 1992-03-11
Abstract: A method of manufacturing an open top, walled member (11) for containing a molten metal, especially a flowing molten metal or repairing or reconstructing a worn or damaged member includes the step of forming the inner walls (19) or a mold which define the inner surfaces of the walled member of an open metal mesh screen (21) which is meltable by the molten metal which is to be contained and transferring, usually by pumping, an alumina-silicon carbide casting compound (37) into the space between the open mesh metal screen and the outer walls (15) defining the mold, which outer walls may be in situ structures. If an existing walled member is being repaired or reconstructed, any damaged or worn portions of the existing walled member are removed and the casting compound is poured in to replace these portions. The next step is to apply heat to dry the casting compound while the open mesh screen of the mold remains in place in contact with the casting compound. The final step involves removing the open screen mesh by flowing hot molten metal into the open top, walled containment member. <IMAGE>

Inventor: MOURE WILLIAM B JR
IPC: H01M10/54
Filed: 1992-03-19
Abstract: A  method  and  apparatus  for  recovering  lead  from  scrap lead/acid batteries involves first mechanically breaking up the batteries into small pieces, then feeding the small pieces into a substantially vertical,  upwardly diverging  separation/leaching column through which ammoniacal ammonium sulphate solution (AAS) passes upwardly at a speed that allows the removal of metallic lead and lead alloys as sinks from the bottom of the column,  with comminuted case material floating up and out of the column, while the lead compounds remain in suspension in the column for lead sulphate dissolution.  The insoluble lead dioxide from the pastes is removed from the AAS downstream of the column and is slurried with sulphuric acid to convert the lead dioxide to lead sulphate, which is then returned to the separation/leaching column.   The clarified AAS is fed to an electrowinning tank where metallic lead is plated out.  Make-up anhydrous ammonia is fed into the bottom of the column, while ammonium sulphate being produced from sulphuric acid neutralization and lead sulphate reduction is recovered for fertilizer.

Abstract: An apparatus for filtering liquids, such as fibre pulp suspensions or polluted water, includes annular hollow filter discs (5), each of which has two annular liquid pervious, opposed walls (5, 7) covered with filter material, spray nozzle means (15-17) for cleaning the filter material, and means (12) for providing relative movement between the filter material and the spray nozzle means. The annular opposed walls of each filter disc are only attached to each other at their radially outer ends, whereas they are spaced from each other at their radially inner ends, such that an annular opening is defined between the interior of the filter disc and a filtrate chamber (11) extending centrally through the filter discs. The spray nozzle means (15-17) extends from the filtrate chamber through the annular opening into each filter disc. As a result, an extremely pure fine fraction can be produced, clogging of the filter material is efficiently counteracted, and the operative part of the filter material can be increased.

Patent CA-2077427-A1 (CA)
Inventor: SAKAI ICHIRO
IPC: F16H59/48
Filed: 1992-09-02
Abstract: In a system for controlling  a gear ratio of a multi-step geared or continuously variable automatic transmission of a vehicle, the gear ratio is determined through fuzzy production rules each having one of an ATF temperature, a steering or an engine coolant temperature.  For example, the rule regarding the ATF temperature defines such that the gear position should be shifted down if the ATF temperature is high.   With the arrangement, when the ATF temperature is high, the gear position is determined in the downshifting direction so that the amount of torque converter slippage can be reduced, whereby avoiding temperature rise in the transmission.  And since the engine speed is relatively high at that situation, motive force could be sufficient even climbing a hill.

Abstract: An atrial defibrillator (30) reliably detects a depolarization activation wave of the heart and delivers cardioverting electrical energy to the atria of the heart in synchronism with a detected depolarization activation wave. The atrial defibrillator includes a first sensor (53,52) for producing a first electrical output having a duration substantially equal to the duration of the depolarization activation wave sensed between a first pair of spaced apart locations (38a,40a) of the heart. The atrial defibrillator further includes a second sensor for producing a second electrical output having a duration substantially equal to the duration of the depolarization activation wave sensed between a second pair of spaced apart locations of the heart. The spacing between the second pair of locations is greater than the spacing between the first pair of locations. A microprocessor (60) is responsive to the first and second electrical outputs for providing an indication signal indicating the occurrence of the depolarization activation wave when the second electrical output is longer in duration than the first electrical output. A pulse generator (66) coupled to the microprocessor applies electrical cardioverting energy to the atria of the heart in response to the indication signal. <IMAGE>
