Title: Heat source for a smoking article
Inventor: SCHLEICH DONALD M
IPC: A24D1/22
Filed: 1989-12-06
Abstract: ABSTRACT         (Fig.2) HEAT SOURCE FOR A SMOKING ARTICLE    A heat source 20, when ignited, produces hot gases which release flavourant vapours from a flavourant bed 21.  The mixed gases pass through an expansion chamber 12 to a mouthpiece 13.       The heat source comprises metal carbides, preferably iron carbides Fez C and/or Fe5 C2, which ignite at relatively low temperatures (less than 550°C) and liberate substantially no carbon monoxide.  The carbides are preferably in particulate form and may be mixed with carbon and held together by a binder.  The heat source 20 is preferably cylindrical with air passages 22 running through it.

Title: Enhanced efficiency valve actuator
Inventor: RICHESON WILLIAM E JR
IPC: F01L9/20
Filed: 1990-01-03
Abstract: PHA 40.554                              30-06-1989 ABSTRACT      A bistable electronically controlled fluid powered valve actuator for use in an internal combustion engine of the type having engine intake and exhaust valves has a piston reciprocative in a cylinder housing for driving the engine valves to open and close.  Control valves are mounted separately from the piston for reciprocative movement in the housing and are used to selectively direct air pressure to drive the piston.  The control valves are magnetically latched in closed positions with the magnet force used to also close ends of the valves.  Abutments are affixed to ends of the piston shaft to aid the control valves in their closing movements, especially if the valves have a transitory retardation; another aid to valve closing movement is the capture of air in a chamber that is sealed on opening valve movement so that the compression of air in the chamber acts as an air spring to aid in the valve closing movements.

One embodiment includes a constraint chute below said the heat sealing jaws of the machine. The constraint chute comprises two vertical walls which axe adapted to permit a material-filled pouch to travel therebetween, the pouch being formed by transversely heat sealing a material-filled tubular film at intervals, using the jaws to form the seals, one of the walls being adapted to move away from the other wall under tension and to return to its original position, the degree of tension and the friction of the walls being sufficient to squeeze the pouch therebetween and to permit the pouch to travel therebetween without undue restraint, the plane of both of the walls being perpendicular to the direction of closing of the jaws. Another embodiment includes a) a pair of transverse heat sealing jaws with at least one of the jaws being capable of transverse motion and adapted to collapse a tubular film, horizontally, passing between the jaws, b) a pair of spreader fingers adapted to be inside the tubular film and to shape the tubular film towards a layflat configuration, such layflat configuration having longitudinal edges, thus spreading the longitudinal edges of the tubular film outwardly, one of the spreader fingers being fixed, the free ends of the spreader fingers being located close to and above the jaws, and c) one or two pairs of detucker fingers which are adapted to act in unison with the transverse motion of the heat sealing jaws, located close to the heat sealing jaws and adapted i) to pinch a longitudinal edge of the tubular film such that when the tubular film has been pinched by the detucker fingers, the detucker fingers are close to such longitudinal edge of the tubular film, and ii) to urge the pinched tubular film transversely in a direction substantially para11e1 to the closing surfaces of the jaws and away from the other longitudinal edge of the tubular film.

Abstract: An improved pressure swing adsorption process is disclosed for the recovery of high-purity primary and secondary components from a multicomponent gas mixture.  The process utilizes a first group of adsorbent beds selective for the secondary component and a second group of adsorbent beds selective for retention of tertiary impurities in the mixture.  The gas mixture is passed through a first and second bed in series, very high purity primary component product is discharged from the second bed, and high purity secondary component product is recovered by desorption from the first bed.  A low-pressure purge of the first bed with high-purity secondary component product is utilized to minimize compression power and improve purity of the secondary product component.  Several novel pressure equalization steps improve primary product recovery and reduce power consumption.  Further increased product recovery is realized by recycling depressurization and purge streams from the first bed. The process can be used to recover high-purity hydrogen and carbon dioxide from a gas mixture containing these components along with minor amounts of methane, carbon monoxide, and nitrogen.

Title: Method and apparatus for fast generation of warping coefficients
Inventor: WALTZ FREDERICK M
IPC: G06T3/00
Filed: 1990-03-26
Abstract: ABSTRACT           A polynomial warp of a first image for comparison with a second image is performed by precalculating and storing a matrix for use in determining the warping coefficients.  A group of control points is preselected in the second image and located in the first image.  The matrix products of the precalculated matrix and each of two column vectors containing the coordinates of the control points in the first image are calculated.  The results of this matrix multiplication are two column vectors containing the warping coefficients.  Those coefficients are then used to perform the image warping.

Title: Weaving process
Inventor: ROSSMAN CHRISTOPH
IPC: D03C13/00
Filed: 1990-11-09
Abstract: ABSTRACT OF THE DISCLOSURE           In a weaving process the weft threads are positioned into the warp of the fabric by means of at least one small shuttle.  This allows the shed-forming displacement of the warp threads for the insertion of the weft thread by the forward motion of the shuttles themselves, as well as ensuring a high process rate, high product quality, and a quiet and dust-free operation.  To this end, the shuttle is equipped with sensors for the detection of the warp thread position and with an arrangement for displacing the warp threads.  It can thus determine its own path through the warp for the insertion of the weft in order to form the weave.

Abstract: According to this invention, a plurality of recognition candidates are obtained through continuing a segmentation to a numeral recognition realized by segments, an optimum one is selected from among the candidates by means of connection information, thereby preventing the continuous numerals from being recognized erroneously.  This invention is a method of correctly recognizing the handwritten characters, especially the numerals written in such as a checks, said method which comprises the steps of: performing a line drawing analys is of the character set to be recognized in order to extract a characteristics of the arrangement of blocks, proposing a hypothesis about the monetary unit type, and finally verifying the above hypothesis to display the result of the character recognition.  Further, this invention method can surely distinguish handwritten characters from a bar which is either printed for entry of characters or  handwritten, and eliminate the bar from the object of character recognition to extract the characters alone.  In detecting the bar, six formulas for under-bar, middle-bar, upper-bar, inclined bar, inclined under-bar and inclined upper-bar as relative to the characters are used to determine certainty factor of a bar, and the bar having the highest linearlity is extracted.

Abstract: A body implantable electrode (20,68) includes a platinum wire or filament (28,40,46,52,70) compressed and bundled into a serpentine configuration and retained within a platinum screen (30), thus to form a highly porous electrode. The electrode body is then surface treated by vapor deposition or vapor deposition in combination with electroplating, to provide an adhesion layer (38,48,54), a texturizing layer (38,50,56), and one or more catalytic cover layers (44,58,60). The texturizing layer, which can be titanium, carbon black or aluminum, is formed with multiple nodules and depressions which substantially increase the reactive surface area of the electrode. The catalytic layer can be platinum, platinum-black or platinum followed by a layer of carbon. The combination of macro porosity and micro texture provides an electrode that promotes tissue ingrowth after implant and maintains a low chronic stimulation threshold due to its large reactive surface area in proportion to its geometric size. <IMAGE>
