摘要： Method and apparatus are provided for reducing vibration in bearings. There are provided first and second bearing rings with races, rotating members rollingly engaging both first and second bearing races, a cage for aligning the rotating members between the first and second bearing races, and vibration reduction means coupled to the cage. The vibration reduction means preferably comprises one or more resonant spring-mass combinations mounted in or on the cage. Damping means is preferably included with the resonant spring-mass combinations. The resonant frequencies of the unmodified bearing cage are first determined and then the spring-mass combinations tuned so that the spring-mass combinations when attached to the cage absorb vibrational energy that would otherwise excite cage vibrations. By selecting the type of spring-mass combination different vibrational modes can be suppressed and/or controlled.

摘要： A lens array and a method for fabricating the lens array are described herein. The lens array is made from a photosensitive glass plate containing a relatively small amount of a photosensitive agent (e.g., silver, gold or combination thereof) such that when the photosensitive glass plate is subjected to an exposure step, a heat treatment step and an optional ion exchange step it becomes a glass composite plate that includes glass regions which are lenses and also includes an opaque opal region located around each of the lenses. The lens array has clear, colorless lenses exhibiting greater sag heights than those yellow lenses found in a traditional lens array made from the traditional photosensitive glass plate which was subjected to similar exposure, heat treatment and ion exchange steps.

摘要： Fluoropolymers consisting of alternating perfluorocyclobutane and aryl ether linkages possess suitable properties for optical waveguides and other devices using refractive properties of the polymers. Perfluorocyclobutane (PFCB) polymers having aryl groups alternating on an ether chain have shown useful physical properties for optical waveguide applications. Processes for micromolding such polymeric films by replicating a pattern or image directly from a silicon master, rather than from a polydimethyl siloxane (PDMS) mold) are disclosed.

摘要： A rotating, conductive, heat transfer device is provided. The device includes an outer race having an axis, an inner race coaxial with the outer race, and a plurality of bearing balls disposed in a radial direction between the inner race and the outer race. The device also includes a plurality of separators disposed alternately in a peripheral direction between the bearing balls. The device has a first track and a second track, supported by the inner race, for supporting the separators. The inner race has a first, fixed, inner ring portion with a first bearing surface, and has a second, separable, inner ring portion with a second bearing surface. The outer race has a third bearing surface, disposed in a radial direction opposite to the first bearing surface. The outer race also has a fourth bearing surface, disposed in a radial direction opposite to the second bearing surface. The first and second and third and fourth bearing surfaces are in contact with a spherical surface of each bearing ball. The device also has a plurality of coil springs, which urge the second inner ring portion in an axial direction toward the first inner ring portion, thereby applying first and second and third and fourth forces normal to the respective first and second and third and fourth bearing surfaces, for providing heat conduction from one race to the other race.

摘要： This invention is directed to a method for modifying the coloration produced in a silver halide-containing photochromic glass when heat treating the glass at a temperature not exceeding 450.degree. C. under reducing conditions. The method comprises subjecting such a glass having a base composition which contains at least 1% by weight Li.sub.2 O, at least 2% by weight Na.sub.2 O, and at least 6% by weight Li.sub.2 O+Na.sub.2 O+K.sub.2 O to an ion exchange reaction, wherein lithium ions, and potassium ions, when the latter are present in the composition, in the glass surface are exchanged with sodium ions from an external source, prior to the reduction heat treatment.

摘要： A Type I Traffic Barricade is described having a reflective panel mounted between a pair of leg supports. Each leg support has two legs pivotally secured together at an upper end and in a spaced relationship by a pair of brackets on opposing sides of the leg support. The brackets are placed into slots formed on an underside of the reflective panel and, with the legs spread for the widest possible stance at their lower end, the upper end is biased against the reflective panel for complete and stable vertical and lateral support, while allowing easy set-up and knock down with minimum space requirements for storage.

摘要： This invention is concerned with the production of composite articles comprising a glass or glass-ceramic matrix containing long fibrous single crystals of rutile (TiO.sub.2) of very high aspect ratios grown in situ. The glass articles are formed via the heat treatment of a molten batch consisting essentially, by weight on the oxide basis, of about 45-65% B.sub.2 O.sub.3, 5-30% Al.sub.2 O.sub.3, 5-30% TiO.sub.2, and 3-30% alkaline earth metal oxides and can exhibit greatly improved mechanical strength and toughness when compared with the original, or fiber-free, glass. The glass-ceramic articles are formed by heat treating the fiber-containing glass in a particular manner to cause the development of fine-grained crystals in situ, resulting in a highly-crystalline article containing long fibrous single crystals of rutile exhibiting verh high aspect ratios.

摘要： The present invention is generally directed to a process for producing lactide-based polymers and the polymers produced by this process. The polymers of the present invention are terpolymers formed by the copolymerization of a lactide monomer, a linking monomer and an epoxy-terminated monomer. In one embodiment of the invention, the polymers may be formed from fluorine-containing monomers or aromatic ring-containing monomers. The disclosed materials may display improved hydrolytic and thermal characteristics as compared to previously known lactide-based materials. For example, the lactide based terpolymers may have a glass transition temperature over 60° C. For instance, lactide-based thermoplastic terpolymers of the present invention can have a glass transition temperatures of about 80° C. or higher. Lactide-based thermoset networks of the invention can have glass transition temperatures of up to about 200° C.

摘要： Crystalline colloidal arrays (CCA) which have been encapsulated in a polymer matrix to produce more robust polymerized crystalline colloidal arrays (PCCA) are provided. The PCCA's of the present invention can be in the form of a hydrogel which can be compatible for use with a biological system. The polymer matrix of the PCCA is formed of polymerized poly(ethylene glycol) based monomer units which can provide a desired functionality to the PCCA. The PCCA can be formed to exhibit a photonic bandgap at a certain wavelength. The photonic bandgap can be capable of shifting upon some form of environmental stimulation rendering the PCCA suitable for many optical applications, including active photonic switching and sensory applications.

摘要： A signal transfer assembly that is configured to transfer one or more electrical signals between two or more conductive paths that are rotating relative to one another includes two substrates or more substrates and one or more interface assemblies. The substrates each include one or more conductors on one or more surfaces. Each interface assembly is disposed between two substrates and is configured to allow relative rotation between the two substrates. Each interface assembly also electrically couples selected ones of the conductors on each of the substrates together, thereby allowing electrical signals to pass through the assembly.
