Abstract: An imaging mount and apparatus that reduces or eliminates stress induced in an imaging mask mounted thereto. The mount comprises a support block and a trio of mounting pads connected thereto. At least two of the mounting pads are connected to the support block so that their respective positions are adjustable within a predetermined plane which is preferably substantially parallel to a surface of a substrate to be imaged. Each of the mounting pads including means for securing the imaging mask generally parallel to the predetermined plane. The positions the adjustable mounting pads adjust within the predetermined plane responsive to securing of the lithography mask thereto so that the imaging mask is essentially undeflected due to the securing thereof. The absence of deformation (and, as a result, stress) in the imaging mask due to its being secured to the mount reduces the degree of distortion of radiation passing through the mask and to the imprinted surface.

A luminescent fiber comprising a thermoplastic polymer and metal aluminate oxide pigment, and articles of manufacture comprising such fibers are also provided.

Abstract: The invention relates to an improved method and apparatus for producing paper board structures wherein two corrugated mediums are bonded together at their flute tips. End gears (16a, 16b, 15a, 15b) are provided, at least, on the ends of the corrugating rolls (4,6), which are non-meshing with each other and which assist in aligning the corrugated mediums in tip to tip arrangement and provide precise tip to tip bonding of the mediums. The end gears may be abutting or non abutting and may be provided on both ends of the corrugating rolls, which assist in aligning the mediums to obtain precise tip to tip bonding.

Abstract: Disclosed is an ultrasonic phase aberration correction method and apparatus. One preferred embodiment employs a translating transmit aperture for transmitting two separately transmitted pulses through two different transmit apertures but which are focused to the same predetermined target in the human body. A receiver element measuring a first echo from a first transmit pulse is matched with a receiver element measuring a second echo from a second transmit pulse from a translated aperture, the match corresponding to receivers with a separation equal and opposite to the spatial translations of the translated transmit apertures. The matched elements are compared for signal variations which estimate phase aberrations and especially improve on estimates of distributed aberrations. The transmit or receive signals can then be compensated for or adjusted based on the signal comparison and variation estimates.

Abstract: A mount for rotatably supporting a winding unit which comprises printed products which are wound upon a core and which has a winding band which is connected to the core of the unit and wound with the products. The mount includes a bearing arrangement for rotatably supporting the winding unit and which is elevationally displaceable, and the mount also includes a rest element upon which the winding band rests when the winding unit is lowered. This prevents the winding band from being released and the winding unit from falling apart. The mount can be docked onto an unwinding station, which includes provision for lifting the winding unit off from the rest element so that the printed products can be unwound.

Abstract: The present invention involves isolated nucleic acid molecules encoding the equine herpesvirus-4 (EHV-4) gH or gC polypeptide, the polypeptides so encoded, and antigenic fragments thereof. Vectors and host cells containing these nucleic acid sequences, and uses thereof, are presented.

Abstract: The present invention provides a process for making fluorinated polymers and copolymers having stable end groups. The process includes (1) contacting a fluoromonomer, an initiator capable of producing stable end groups on the polymer chain, and a polymerization medium comprising carbon dioxide, and (2) polymerizing the fluoromonomer. The polymerization medium preferably comprises liquid or supercritical carbon dioxide. Advantageously, the process may also include the step of separating the fluoropolymer from the polymerization medium.The present invention also provides polymerization reaction mixtures useful in the processes of the present invention.

Abstract: An assay for detecting the presence and amount of a hormone in culture media or a biological sample includes the steps of preincubating two antibodies specific for the hormone to be assayed in a preincubation medium that is essentially free of the hormone to be detected, contacting a sample to be tested with the preincubated antibodies, and detecting hormone-antibody complexes formed in the contacting step. This assay reduces or eliminates non-specific interference and thereby increases the sensitivity of the assay.

Abstract: A method of determining strength and related mechanical properties of paper and similar products, both on-line and off-line using a continuous ultrasonic swept frequency wave transmission and reception system. The invention also provides an apparatus for measuring the strength and related mechanical properties of paper.

Abstract: Peritoneal fluid and peritoneal wash fluid provide a source of abundant apolipoprotein E. Methods for isolating apolipoprotein E from peritoneal fluid or peritoneal wash fluid are provided.

Abstract: The present invention provides a multi-phase polymerization process for making a water insoluble polymer. The process includes (1) providing a mixture comprising carbon dioxide and an aqueous phase, and containing a monomer and a polymerization initiator, and (2) polymerizing the monomer in the reaction mixture. The monomer may be a hydrocarbon or a fluorinated monomer. The polymerization initiator may be soluble in the aqueous phase, soluble in carbon dioxide, or insoluble in both the aqueous phase and carbon dioxide, such that the initiator forms a separate phase.The present invention also provides multi-phase polymerization reaction mixtures useful in the process of making water insoluble polymers.

Abstract: Active esters of PEG acids and related polymers are provided that have a single propionic or butanoic acid moiety and no other ester linkages. These polymer acids have a half life in water of from about 10 to 25 minutes. For example, alpha-methoxy, omega-propionic acid succinimidyl ester of PEG ("methoxy-PEG-SPA") has a nearly ideal reactivity with amino groups on proteins and other biologically active substances. The half life of methoxy-PEG-SPA is about 16.5 minutes in water. The invention also provides conjugates with proteins, enzymes, polypeptides, drugs, dyes, nucleosides, oligonucleotides, lipids, phospholipids, liposomes, and surfaces of solid materials that are compatible with living organisms, tissue, or fluid.

Abstract: A conductive strap configured to attach to a circuit board containing a component sensitive to electronmagnetic interference (EMI) and to slidably contact an enclosure having a conductive internal surface can reduce or eliminate EMI in an electronic device. The strap is positioned on the circuit board to shield the sensitive component from EMI. Slidable contact between the shielding strap and the enclosure internal surface renders the strap suitable for almost any enclosure configuration without any design modification.

Abstract: A diamond-based structure includes a substrate, an adhesive material on a face of the substrate, and an array of spaced apart diamond mesas bonded to the substrate by the adhesive material. In particular, each of the diamond mesas can have a growth surface adjacent the substrate and an interfacial surface opposite the substrate, and the interfacial surface can be smooth relative to the growth surface. This structure can be fabricated by providing a sacrificial substrate, forming a plurality of diamond mesas on a face of the sacrificial substrate, bonding the diamond mesas to a transfer substrate, and removing the sacrificial substrate. Accordingly, the interfacial surfaces of the diamond, which are formed adjacent the sacrificial substrate and then exposed by removing the substrate are smooth.
