Abstract: A system receives information for a plurality of invoices having invoice amounts owed by a debtor-buyer to a plurality of creditor-suppliers, a cash pool amount for a cash pool available by the debtor-buyer for early payment of at least some of the invoice amounts, and a desired return rate, receives a plurality of offers, each offer from a corresponding creditor-supplier and comprising an offer return rate, determines whether each of the plurality of offers is eligible for acceptance based on each offer return rate from each offer and the desired return rate for the buyer and selects one or more invoices each having an invoice amount, and transmits award information to the debtor-buyer.

Abstract: An oxygen sensor comprising an oxygen sensing compound and configured to substantially mitigate leaching of the oxygen sensing compound from the oxygen sensor to an outer surface thereof is provided. The oxygen sensor may comprise one or more layers. A first portion of the oxygen sensor is configured to be permeable to gas and comprises an oxygen sensing material. A second portion is disposed with or on the first portion and is configured to be permeable to gas and substantially impermeable to the oxygen sensing material.

Abstract: A rivet setting tool having a motor driven hydraulic pump is disclosed. The rivet setting tool incorporates a fastener setting verification system configured to monitor changes pump drive motor current to determine if a particular fastener set is acceptable.

Abstract: A riveting system is operable to join two or more workplaces with a rivet. In another aspect of the present invention, a self-piercing rivet is employed. Still another aspect of the present invention employs an electronic control unit and one or more sensors to determine a riveting characteristic and/or an actuator characteristic.

Abstract: A rivet monitoring system is provided which has a micro-strain or micro fluid pressure sensor that measures strains or pressures within a tool component. These measured signals are compared to a number of tolerance bands formed about median strain or pressure versus time curve. Various techniques are provided to analyze the measured data with respect to the tolerance bands to determine if a particular rivet set is acceptable.

Abstract: The magnetized punch of the tool breaks off the tang and holds the tang until the punch is withdrawn into an opening in a vacuum conduit. The tang is thereby removed from the punch and it becomes entrained in a vacuum flow, detected and accounted for before passing into a collection chamber.

Abstract: A gate latch for use with a gate mounted for pivotal movement relative to a stationary fence includes a transversely extending latch bar secured to the gate and a latch member pivotally mounted on a mounting plate secured to the fence. In a first embodiment, a safety latch attachment includes an adapter plate configured for partial overlying attachment adjacent the latch mounting plate and having a reciprocal spring biased plunger in alignment with a transverse aperture formed through a latch frame on the mounting plate. When in a latched position, the plunger prevents the pivotal latch member from being unlatched. A pulley guided cable is connected to retract the plunger to allow the gate to be unlatched. In a second embodiment, the safety latch attachment mechanism is provided as an integral unit on a common mounting plate with the pivotal latch member.

Abstract: A nail polish display stand is formed from a cylindrical housing having an open top end and a hollow interior defined by an interior side wall and an interior floor. A plurality of steps are formed in the interior side wall and form perpendicularly intersecting horizontal annular and vertical cylindrical surfaces. The steps increase in diameter from the interior floor to the open top end of the housing. A plurality of various different shades of nail polish color samples are displayed on the horizontal and/or vertical surfaces of the steps. The color samples may be individually provided on artificial nails secured on the steps. The nails may be mounted on a plurality of spaced arcuate mounting surfaces or may alternatively be secured within a plurality of pairs of spaced slots on the steps. The display stand allows an extremely large number of different color shades to be displayed in a small space.

Abstract: A freight pallet may be formed in a wide variety of user determined configurations by assembly of a plurality of interlocking construction units. Each of the units has a square thin support plate with a projecting rib extending along a first pair of adjacent perpendicular side edges. A complementary formed groove extends along a second pair of adjacent perpendicular side edges of the support plate. A right angle corner support member is perpendicularly attached at each corner on a bottom surface of the support plate. Each pair of adjacent corner support members are connected by a support brace. The construction units may be assembled adhesively or through thermoplastic bonding by forming portions of the projecting ribs and complementary grooves from a thermosetting plastic material.

Abstract: A tool sharpening apparatus is set forth particularly for use in combination with grinding wheels wherein multi-adjustment and angularly displaceable supports cooperate to present a desired complex presentation of tool faces to be sharpened. Particularly a base supports a first protractor support by an associated tongue and groove arrangement wherein a second pivotal support is angularly displaceable relative to said first protractor support. A third laterally adjustable support cooperates by a further tongue and groove arrangement with said second pivotal support to secure adjustably a fourth depth adjustment support to orient a tool face relative to a grinding wheel. A fifth protractor support is secured to said fourth depth adjustment support wherein a sixth tool holder support is angularly adjustable relative to said fifth protractor support. Accordingly, any desired grinding of a secured tool may be effected.
