Abstract: A method is provided for carrying out an assay using a rotor assembly (220) comprising a rotor body (222) which is rotatable about an axis of rotation. The rotor body (222) has a central chamber (234) and six chambers (236 to 246) which are in communication with and radiate from the central chamber (234), and the rotor assembly (220) includes a shuttle (224) which is movable through said central chamber (234) into operative registry with any of said six chambers (236 to 246). The shuttle (224) comprises a reaction cup (252) carrying an immobilized antigen or an immobilized antibody for transport among said chambers. The method involves introducing an amount of whole blood into the first chamber (238), wash solution into the second chamber (240), an enzyme conjugate into the fourth chamber (240), an enzyme substrate solution into the fifth chamber and a reagent reference into the sixth chamber. The third chamber (236) is used for drying. The shuttle is moved between the chambers in a specified manner, the rotor body being rotated at various stages in the process, and a product is generated in the fifth chamber for comparison with the reagent reference in the sixth chamber.

Abstract: In cryptographic techniques which are based on the discrete logarithm problem, use is made of exponentiation modulo large number. If, in this method, the exponentiation is first carried out completely and the modular reduction is only carried out thereafter, this requires very considerable computation time and a very large memory capacity. It is known that the exponentiation can be accelerated by iteratively multiplying and squaring, with a modular reduction after each step. The invention provides a method of also accelerating the modular reduction at the same time, as a result of which the exponentiation modulo large number can be further accelerated. For this purpose, the invention describes a protocol for a modular reduction of a 2n-digit number x in a number system with base b to obtain an n-digit remainder, in which use is made of a specific modulus p which satisfies p = b<n> - a, where 0 < a < b. The method according to the invention does not reduce the security of the cryptographic system for which the modular exponentiation is carried out. <IMAGE>

Abstract: Methods for fabricating two-dimensional imaged metal articles on webs by electroless deposition of metal onto a catalytic pattern rotogravurely printed onto moving webs travelling at linear speeds of up to 500 meters/minute using low viscosity catalytic ink comprising polymer and compound, complex or colloid of a Group 1B or Group 8 metal. Such two-dimensional imaged metal articles comprise areas or fine lines, e.g. less than 100 micrometers wide, which are useful as electrical devices such as circuit connectors, antennas and the like or as mechanical devices such as levers, gears and the like. With modification of the metal component or addition of other materials, such two-dimensional imaged metal articles can be useful a electronic devices such as diodes, resistors, capacitors and the like or as energy conversion devices such as batteries, sensors or fuel cells. The catalytic inks have appropriate rheological properties of viscosity and surface tension that permit non-sagging, non-spreading images to be printed onto a web which can travel vertically into a drying zone.

Abstract: The invention relates to a process for producing multi-layered carbonless sheets on which indicia can be xerographically produced with little or no non-specific development. The process involves coating a sheet with a CB composition containing a carboxymethyl cellulose polymer, a crosslinker, a salt of a polyvalent metal ion and a small amount of a wall forming acrylic resin. The CB coating formed resists breakage and release of dye when non-specific pressure is applied to the sheet thereby resulting in CF copies having improved brightness and reduced non-specific development.

Abstract: A positioning tool has an elongated cylindrical section for reversibly engaging an acetabular cup which is insertable through a posterior opening in the cup. The outer diameter of a proximal portion of the cylindrical section is expandable to engage the inner wall of the cup in an interference fit to prevent movement of the cup relative to the tool and hold the cup in engagement with the tool to move the cup with movement of tool to place the cup for implanting at a desired position. The expanded portion of the tool may be contracted to release it from the cup after implantation. The proximal portion, which is attached to the distal portion and separated therefrom by a partial transverse slot, is divided into semicircular sections by a diametrical vertical slot therebetween. Diametrically opposite quadrants of the proximal portion further contain elongated slots therethrough which are perpendicular to the vertical slot and spaced from the edge of the cylinder by a thin section. The outer diameter of the proximal portion of the cylindrical section may be expanded or contracted by pivoting the semicircular sections around the thin spaces between the elongated slots and edges of the proximal portions. The tool further comprises means for causing the semicircular sections to move relative to each other to expand or contract the diameter of the cylindrical section.
