Title: Use of dna-dependent rna polymerase transcripts as reporter molecules for signal amplification in nucleic acid hybridization assays
Inventor: URDEA MICHAEL S
IPC: C07H21/00
Filed: 1991-01-10
Abstract: A polydeoxynucleotide construct is disclosed for use, in conjunction with a DNA-dependent RNA polymerase, as a signal amplifier in nucleic acid hybridization assays. The construct contains a recognition sequence for a target oligonucleotide, a promoter sequence for a DNA-dependent RNA polymerase, and a polymerase template.  A method of use for this construct in hybridization assays is also disclosed. The method involves formation of a hybridization complex comprising the construct and the target sequence; addition of a polymerase which is specific for the promoter in the construct; and quantification of the resulting RNA transcripts.

Title: Methods and compositions for flavoring orally-delivered products
Inventor: WILLIFORD JOHN H
IPC: A23L27/00
Filed: 1990-10-24
Abstract: Flavored food and pharmaceutical compositions include one or more flavor additives incorporated within polymeric particles, usually within an internal pore network defined by individual polymeric particles. The polymeric particles are, in turn, dispersed within and/or over a surface of an orally-deliverable matrix material, which is usually a solid or semi-solid substrate. In the case of chewable compositions, the flavor additives will be released into the orally-deliverable matrix material as the composition is chewed and held in the mouth, thus prolonging the flavor of the composition. In the case of dried powders and mixes, the flavor will typically be made available as the product is consumed or be released into the matrix material as the composition is further processed. When two flavors are combined with the polymeric particles, the relative amounts of the additives can be selected to provide simultaneous release and exhaustion of the additives.

Title: Method and apparatus for access control and/or identification
Inventor: NACCACHE DAVID
IPC: G06F21/62
Filed: 1992-01-11
Abstract: The present invention relates to a method and to an apparatus for access control and identification which requires no public key directory. For many applications, e.g. smart cards for pay TV  purposes, credit cards, passports, dongles or other kind of electronic keys, unforgeable systems for access control or digital signature are required. Such access control and systems may include public keys. But in many of such public key systems the key management becomes very complicated when the number of users increases.  The invention uses the fact that it is difficult to compute square roots mod n when factoring of n is unknown. The invention is based on the identity: x2 r(x+x-1) 2 = r2 1+x2 2 mod n which is computed and compared using a user unit and a verifier unit. The public key directory is replaced by a unique transmission between a sender and a receiver R of a 'seed' which will give after a proper processing both the identity information for R and public keys.

Title: Coupling Assembly
Inventor: COLLINS MARCUS H
IPC: F16D25/10
Filed: 1993-09-23
Abstract: An improved coupling assembly includes a combined clutch and brake assembly. Springs are provided to urge the brake assembly to an engaged condition. A first pressure chamber holds fluid pressure to assist the springs in urging the brake assembly toward the engaged condition.      A second chamber holds fluid pressure to urge the clutch assembly toward the engaged condition and to urge the brake assembly away from the engaged condition. Fluid is supplied at a relatively low pressure through the first chamber to provide for a controlled actuation of the brake assembly to the engaged condition under the combined influence of the springs and the pressure in the first chamber and to provide for the transmission of a controlled amount of braking torque when the brake assembly is engaged. Fluid is supplied to the second chamber at a higher pressure to overcome the influence of the springs and operate the clutch assembly to the engaged condition.      A quick release valve arrangement is provided in association with the second chamber to enable the fluid pressure to be quickly exhausted from the second chamber and the brake assembly engaged.

Title: Stable Double Emulsions Containing Finely-Divided Particles
Inventor: THILL FRANCIS L
IPC: A01N25/06
Filed: 1992-06-15
Abstract: A preferred method of producing an aqueous, stable double emulsion is disclosed. The first step of the method is the production of an "inner" emulsion. The inner emulsion is produced by combining water, a liquid hydrocarbon solvent, and an emulsifier, in an agitated mixing vessel, along with an effective amount of finely-divided particulate material, to produce an oil-in-water emulsion having a viscosity of no more than about 200,000 centipoises, wherein the finely-divided particulate material is substantially homogeneously-dispersed throughout the thus-produced oil-in-water emulsion. The second step of the method is the production of an "outer" emulsion. The outer emulsion is produced by combining a liquid hydrocarbon solvent, water, and an emulsifier, in an agitated mixing vessel, to produce a water-in-oil emulsion. The third step of the method is the production of a "dual" emulsion. The dual emulsion is produced by combining the water-in-oil emulsion with an effective amount of the oil-in-water emulsion, in a mixing zone, thereby to produce the aqueous, stable double emulsion.
