Title: Method of discovering patterns in symbol sequences
Inventor: UNDERWOOD DENNIS JOHN
IPC: G16B30/00
Filed: 2001-05-09
Abstract: A method of discovering one or more patterns in two sequences of symbols S1 and S2 includes the formation, for each sequence, of a master offset table that groups for each symbol the position in the sequence occupied by each occurrence of that symbol. The difference in position between each occurrence of a symbol in one of the sequences and each occurrence of that same symbol in the other sequence is determined and a Pattern Map is formed. For each given value of a difference in position the Pattern Map lists the position in the first sequence of each symbol therein that appears in the second sequence at that difference in position. The collection of the symbols tabulated for each value of difference in position thereby defines a parent pattern in the first sequence that is repeated in the second sequence. A computer readable medium having instructions for controlling a computer system to perform the method and a computer readable medium containing a data structure used in the practice of the method are also disclosed.

IPC: A61F2/24
Filed: 2001-06-20
Abstract: An anatomically designed atrioventricular valve is made of biologically compatible synthetic membrane or biological membrane of autologous, homologo us or heterologous origin. A single piece of the selected membrane material is trimmed so as to form two unequal sheaths similar to the normal anterior and  posterior mammalian mitral valve leaflets with a wide upper base to be sutur ed to the host's mitral annulus. These two leaflets are prolonged and tapered into two thin bands to be connected to the papillary muscles serving as replacements for the natural marginal chordae tendinae of the normal mitral valve. The two lateral sides of the membrane are joined to form a truncated cone with a wider upper circular base and a narrow extremity formed by the thin chordal bands. A set of sutures are placed between selected points at t he base of the cone and the two thin prolongations serving as replacements for the strut or stay basal chords of the natural mitral valve. Thus, the mitral  valve prosthesis is anatomical because it is stentless, bicuspid and support ed by marginal and basal chordae. Obturators and sizers in the configuration of  rods of varying diameter, to measure the host's valve annulus diameter and select the appropriate size of the prosthesis are used during implantation o f the prosthesis. A rod shaped holder maintains the prosthesis during implantation, and a curved bodied measuring instrument is used to determine the precise location where the chordae tendinae of the prosthesis are to be sutured to the papillary muscles of a recipient mammal.

Abstract: The present invention relates to an NH3 injection rate control technique for suppressing an NO X concentration to below a desired NO X concentration through the use of an NH3 injection rate reaching a minimum. In the NH3 injection rate control method for an NO X removal apparatus according to the invention, an operating area of the NO X removal apparatus is divided into a first area in which a molar ratio of an NH3 injection rate with respect tc an NO X flow rate at an inlet of the NO X removal apparatus is smaller than a molar ratio at a minimum point where an NO x concentration assumes a minimum value and a second area in which the molar ratio vs equal to or larger than the minimum point molar ratio, and a virtual NO X concentration with respect to the molar ratio is set according to a virtual characteristic line which varies monotonicallv to stride across a desired operating point without rising with an increase of the molar ratio from the first area to the second area. Moreover, feedback control is implemented for adjusting the NH3 injection rate with respect to the NO X flow hate on the basis of a deviation between a desired NO X concentration and the virtual NO X concentration in a direction that the virtual NO X concentration is brought close to the desired NO X concentration.

Abstract: Axially spaced, pressure-energized seals in a sealing assembly are carried in a conventional seal assembly housing. The seals surround a rod that reciprocates through the housing to power a fluid pump. The seals are pressure-energized by a flowable sealant that is injects through the housing into a confined annular area defined between the seals. The sealant maintains warn seals in close scaling engagement with the reciprocating rod to prevent fluid or pressure loss from the pump. The sealant pressure resists the repeated flexing stresses exerted by the axial rod movement to minimize seal fatigue wear. Components of the seal assembly may be split to permit seal repair or replacement without requiring the removal of the rod from the assembly. The pressure and composition of the flowable, injectable sealant cooperate with the split seal assembly components to prevent leakage across the seal component splits.

Abstract: A bucket elevator conveyor system of the straight horizontal, "C" and "Z" configurations. In these bucket elevator conveyor systems, loading of the buckets can occur anywhere along the horizontal run adjacent the take-up end and discharge of the buckets can be made at the drive area or along the bottom run of the upper horizontal sections of the "Z" and "C" configuration. This provides not only for discharge of the product from the buckets traveling along the lower path of the conveyor, but also provides for simple, intermediate discharge. In addition, there are provided relapping mechanisms to assure proper relapping of the buckets, This is accomplished by reason of a unique bucket design having a cam on one end combined with the front and rear flanges angled to assure proper operation and lapping of the buckets.

IPC: C01B33/158
Filed: 2002-04-16
Abstract: A method is described for enhancing mass and heat transport of fluids in a fine pore structure through an appropriate modulation of the fluid pressure. For example, in an air drying process for a porous material that contains liquid, the air pressure is modulated throughout the volume of the drying chamber. Alternatively, the fluid pressure is modulated in a process stream. As an example, this method can be used for rapid drying of any open porous substances ranging from small pored materials such as aerogels and xerogels, to larger pored substances or articles such as industrial articles, agricultural articles (e.g., densely stacked vegetables, coffee beans, hops and other grains), paper-based products, thin, films, pharmaceuticals, cloth , and clothing.
