Title: Electrically conductive compositions and methods for the preparation and use thereof
Inventor: CAPOTE MIGUEL A
IPC: H05K3/46
Filed: 1992-10-01
Abstract: Electrically conductive adhesive compositions and methods for the preparation and use thereof; in which a solder powder, a chemically protected cross-linking agent-with fluxing properties and a reactive monomer or polymer sue the principal components. Depending upon the intended end use; the compositions comprise three or more of the following: a relatively high melting metal powder; solder powder; the active cross-linking agent which also serves as a fluxing agent; a resin; and a reactive monomer or polymer. The compositions are useful as improved conductive adhesives, such as for attaching electrical components to electrical circuits; the compositions comprising metal powder are ideally suited for creating the conductive paths on printed circuits. The compositions for forming conductive-paths may first be applied to a substrate in the desired pattern of an electrical circuit, and then heated to cure it. During heating, the action of the cross-linking agent and optional reactive monomer or polymer within the mixture fluxes the metals, enabling sintering to occur between the metal powder and the solder powder.

Title: Optical character recognition and item matching assisted by progressively decreasing match criteria
Inventor: THOMPSON RALPH E
IPC: G06V10/98
Filed: 1994-09-08
Abstract: An assisted character recognition process is described which utilizes the relative position of an amount from a negotiable instrument,  such as a check or credit card receipt,  in a sequence of such amounts and compares its relative position to the relative position of an identical amount in a sequence of amounts on a second source, such as an adding machine tape, in order to determine the order of the items; the process also establishes  matching  elements  which  may  be  varied  in stringency  during  sequential  iterations  of  the  matching process whereby the relaxation of the matching criteria will sequentially result in increased matches to allow the largest possible number of matches between the "courtesy" amounts on the checks and the amounts or entries on the second source or adding machine tape. This process is especially useful for matching handwritten entries to similar entries on a second source list such as an adding machine tape, or other such printout.

Title: Flat line boom
Inventor: VANASSCHE CHARLES R
IPC: A01K91/08
Filed: 1994-10-20
Abstract: ABSTRACT OF THE DISCLOSURE           A flat line boom apparatus holds a fishing rod on a boat and guides a fishing line laterally outward from a gunwale of the boat so that the line resists entanglement with other fishing lines also extending from the boat.  The apparatus includes a cylindrical sleeve which slides into a conventional fishing rod holder mounted in the gunwale of the boat.   The sleeve is secured within the rod holder utilizing a bayonet lock to engage the cross pin of the rod holder.  an annular collar is detachably connected to the sleeve so as to allow rotation of the collar about the sleeve.  An elongate boom is attached to the collar so as to extend laterally outward from the gunwale of the boat.  A fishing line clip is attached to the end of the boom for releasably retaining the line near the surface of the water. The line guide releases the line when a fish strikes.   A shock cord extends between the boat and the end of the boom to provide additional support for the boom.  The sleeve is normally inclined when installed in the rod holder so that rotation of the collar and boom about the sleeve will vary the height that the boom is held above the water.   This arrangement allows the boat to turn without entangling fishing line because the lines are positioned at different heights.

Title: Wide-angle polarizers
Inventor: HANNAN PETER W
IPC: H01Q15/24
Filed: 1994-09-09
Abstract: The usable range of incidence angles for electromagnetic wave polarizers using arrays of polarizer elements (10) is increased by introduction of a dielectric medium (18) having a dielectric constant large enough to reduce the angle of wave incidence upon the polarizer elements. For example, arrays (10, 11, 12) of 45 degree inclined meander-line polarizer elements (14) are encased in a dielectric medium (18) having a dielectric constant of about 3. The polarizer (16) includes impedance matching layers (24, 26) at the surfaces of the dielectric medium (18) to reduce reflections at those surfaces. The resulting polarizer is indicated to be usable to reciprocally convert an incident polarization to a desired polarization (e.g., from linear to circular polarization) for waves with incidence angles from 0 to 70 degrees in any play. Polarizers, antennas and methods for changing polarization are described.

Title: Process for continuously controlling the heat content of a partial oxidation unit feed-gas stream
Inventor: SUGGITT ROBERT MURRAY
IPC: G05D21/02
Filed: 1995-06-01
Abstract: A process is provided for continuously controlling the hydrocarbon heat content and flow rate of a partial oxidation unit feed-gas stream under conditions where the composition and hence the hydrocarbon heat content of the feed-gas stream is subject to variation. The hydrocarbon heat content of the incoming gases is continuously measured and compared against a design hydrocarbon heat content. An evaluating means calculates whether a moderator is required to decrease the hydrocarbon heat content to the design hydrocarbon heal content or a supplemental high hydrocarbon heat content gas is required to increase the hydrocarbon heat content to the design hydrocarbon heat content. The process utilizes recycle synthesis gas as a moderator. Once the determination is made, the process automatically adjusts flow rates of the recycle synthesis gas stream, the supplemental high hydrocarbon heat content gas stream and the incoming feed- gas stream to provide a partial oxidation unit feed-gas stream with a constant optimum hydrocarbon heat content and flow rate.
