Abstract: Device for use in adding or dropping light signals at predetermined center wavelengths to or from a wavelength division multiplex, fiber optic transmission system. The device includes an evanescent wave coupler having a coupling region formed from two single mode waveguides, the coupling region being formed so that there is substantially complete evanescent field coupling of light from one waveguide to the other in a predetermined wavelength band. Further, the device has a Bragg grating disposed in the coupling region in each of the waveguides.

Abstract: The present invention relates to a coupling (10) for connecting railing members (170, 171) to post (14, 15). The coupling (10) has a mounting portion having two parts (16, 117) pivotally movable relative to one another and capable of being locked against pivotal movement by a fastener (35, 113). Railing connection members (22, 25) are pivotally coupled to parts (16, 17) about axes (24, 26) extending transversely of the members and to an axis (20) about which the parts (16, 17) may pivot relative to one another.

Abstract: Isolation of a new taxane having pharmaceutical activity, 1a 14-beta-hydroxy-10-deacetyl-baccatine III and hemisynthesis of some derivatives useful as antitumor agents and intermediates.

Abstract: The present relates to laminates which are waterproof blood-proof and virus-proof with a very high moisture vapor transmission rate. The laminate includes a woven or non-woven fabric and an extruded film of 60-70% butylene terephthalate units and the balance a polyester glycol.

Abstract: The present invention relates to the enhancement of suntanning following exposure to sunlight or other source of UV light by topically applying pseudocatalase compounds.

Abstract: A key and lock system is provided for enabling circuits of a vehicle. A key including a plurality of male contacts is inserted into a lock. Predetermined pairs of male contacts are connected to each other. A plurality of female contacts are arranged to receive the male contacts. Circuits of the automobile are connected to the female contacts. If a pair of male contacts is properly mated to a pair of female contacts circuits of the automobile are enabled. The lock can be reversed wire so that either side of the key can be inserted into the lock.

Abstract: Pharmaceutical dosage forms having a linear release rate of the 0.sup.th order for the once-daily oral administration of 20-120 mg of nifedipine or of another calcium antagonist of the dihydropyridine type, characterised by a homogeneous matrix containing 2-50% by weight of hydroxypropylmethylcellulose having an average molecular weight of 20,000-250,000, 5-60% by weight of a calcium antagonist of the dihydropyridine type, as well as customary excipients compatible with the formulation, such as lipophilic or hydrophilic liberation controllers, fillers, flow-regulating agents, lubricants and, optionally, film coatings.

Abstract: This invention relates to a highly tacky pressure sensitive adhesive having superior high temperature properties. The adhesive is formed of about 50-100 parts of a diblock copolymer and about 0-50 parts of a linear or radial triblock copolymer, a tackifier and a curing agent. The adhesive thus formed can be coated on a backing to form a tape and then vulcanized in situ to provide a precured or prevulcanized adhesive tape having high temperature properties and superior tack properties.

Abstract: A method and apparatus is capable of high-speed transportation of passengers and/or freight. Vehicles are operated along a guideway as a result of the interaction between vehicle lift, steering and propulsion apparatus, each of which includes coil assemblies that are mounted on the vehicle, and magnet assemblies mounted on the guideway. Vehicle propulsion is provided by the interaction of currents on the vehicle with time-varying magnetic fields that are generated along the guideway. The coils and magnets interact in accordance with the magnitude of electric current passing through the coils and the strength of the magnets' fields, to give lift and directional control to the vehicle. The lift and steering magnets provide substantially uniform magnetic fields so that the interaction between the lift coils and lift magnets, and respectively between the steering coils and steering magnets is substantially independent of positioning of the corresponding coils.

Abstract: An insect net for screening off at least one air passage which can be opened and closed in variable degree by a shutter. The net is produced from fabric, which is drapeable to a variable extent in dependence of the opening degree of the shutter. In the warp and/or weft direction of the fabric at some distance from each other are inlaid control threads, which are provided at equal intervals to form loops for receiving the control bars of the shutter.

Abstract: Vitiligo and other tyrosinase-positive depigmentation disorders are treated by topical application of a pseudocatalase and subsequent exposure to a sub-minimal erythema dose of UVB light. After a course of treatment, pigmentation of the affected areas can be maintained by treatment with the pseudocatalases without UVB light treatment. The preferred pseudocatalases are transition metal co-ordination complexes, especially manganese (II) bicarbonate.

Abstract: Film-forming flexible collodion compositions can be improved by including one or more topically acceptable polymers in an amount sufficient to increase the resilience of the film formed. Suitable polymers include polyalkylenes and (meth)acrylate homo- or copolymers. The compositions can further include salicylic acid and a topically acceptable crystallization inhibitor in an amount sufficient to suppress the crystallization of dissolved salicylic acid from the composition.

Abstract: A golf putter having an adjustable head with at least one post extending therefrom. A plurality of annular washers are interchangeably secured to the post for changing the center of gravity of the putter head. A hub assembly attaches a shaft to the post. A novel hub locking mechanism locks the hub to the posts in which tapered male portion engages a tapered female portion. Also, a pin and groove arrangement prevents the shaft from rotating further than a predetermined angle from the vertical axis.

Abstract: A rehabilitation system employs a force feedback system, such as a force feedback glove, to simulate virtual deformable objects. Prior to rehabilitation, the patient places his or her hand in a sensing glove which measures the force exertable by the patient's digits. Information from the sensing glove is received by an interface and transmitted to a computer where the information can be used to diagnose the patient's manual capability. The computer generates rehabilitation control signals for a force feedback glove. The patient places his or her hand in the force feedback glove and attempts to bring the digits together as though grasping the virtual object. The force feedback glove resists the squeezing movement of the digits in a manner that simulates the tactile feel of the virtual object. The force exerted by the fingers of the patient is fed back to the computer control system where it can be recorded and/or used to modify future rehabilitation control signals.

Abstract: L-alanyl-L-proline is stereoselectively prepared catalytically hydrogenating an N-(2-iminopropionyl)-L-proline in the presence of a metal hydrogenolysis catalyst and at a pH of less than about 4. Also disclosed are improved processes for production of N-pyruvyl-L-proline in which L-proline and a 2,2-disubstituted propionyl halide are allowed to react at a pH of at least 9 to produce an L-proline intermediate which is hydrolyzed at a pH range of from about 6.5 to about 8.5 to yield N-pyruvyl-L-proline.

Abstract: This invention relates to a method and apparatus for robust delay fault testing of integrated circuits (IC) with built-in self-testing. For the method, hazardous nodes of the IC are determined. Thereafter, the topology of the IC can be modified to include a cut-point at hazardous nodes of the circuit. Input of the IC to the cut-point is diverted to an observation point. An out-put multi-input signature register (MISR) at the observation point generates a first signature. An output MISR provides a second signature for outputs to the IC. During testing, a hazard-free input pattern is applied to the IC and the generated first and second signatures are compared to known correct signatures.
