Abstract: The present invention relates to a method for manufacturing a preform for optical fibers, wherein deposition of glass-forming compounds on the substrate takes place. The present invention furthermore relates to a method for manufacturing optical fibers, wherein one end of a solid preform is heated, after which an optical fiber is drawn from said heated end.

Abstract: A chain link for a track of a mobile machine includes a pin, and a retention ring coupled to the pin at a mechanical joint. A portion of the retention ring fills imperfections of the pin at the joint and the pin remains substantially metallurgically separate from the retention ring. The chain link also includes a first track link defining a hole having a step. The first track link is mounted on the pin such that the retention ring is disposed substantially within the step.

Abstract: Disclosed is a method of heat treating quartz glass deposition tubes at between 900° C. and 1200° C. for at least 115 hours. The resulting deposition tubes are useful in forming optical preforms that can yield optical fibers having reduced added loss.

Abstract: Certain embodiments of the present invention provide a system for medication management including an order entry component and a pharmacy component. The order entry component is capable of writing an advanced order. The advanced order includes one or more related at least one of sub-orders and additives. The pharmacy component is capable of automatically processing the advanced order. The processing occurs without the intervention of a user.

Abstract: Driver training methods, systems, and computer readable media are disclosed. A training method receives sensor information from a vehicle driven along a driving route by an individual, assesses performance of the individual based on the sensor information and an individual mastery level, and adjusts the individual mastery level based on the assessed performance of the individual. The method may be embodied in a computer readable media. A driver training system includes a receiver that receives vehicle sensor information associated with a vehicle being driven along a driving route by an individual and a processor coupled to the receiver that assesses performance of the individual based on the received sensor information and an individual mastery level and adjusts the individual mastery level based on the assessed performance of the individual. Driver training protocols and systems and methods for implementing and transforming driver training protocols are also disclosed.

Abstract: An enclosure cover for collecting and disposing of unwanted moisture within honeybee hives during periods of temperature and humidity conditions that promote alternate freezing and thawing. An internal cover surface collects and condenses moisture produced by the bees' metabolism which otherwise may be deposited on the internal surface of the cover as frost and later thaw, causing droplets of cold water to fall on the clustered bees. The enclosure cover is arranged to direct and channel collected water from the condensation surface and discharge the same outside of the hive.

Abstract: An apparatus configured to a downhole tubular to a pump. The apparatus comprises: a body portion having a bore; a locking assembly comprising at least one locking member pivotally mounted to the body portion so as to permit the locking member to be pivoted between an open position in which the downhole tubular can be inserted into the bore of the body portion, and a closed position in which the locking member engages the downhole tubular so as to lock the downhole tubular in the bore of the body portion. Fixing means is provided for fixing the looking member in the closed position. A method of drilling a wellbore using a borehole casing.

Abstract: The present invention provides a reference solution for use in instruments that determine hematocrit levels in biological samples by measuring the resistance and/or conductivity of the biological samples. A reference solution according to the invention achieves conductivities representative of known hematocrit levels in blood, while maintaining tolerable levels of interference with the measurement of other analytes in the reference solution.

Abstract: A device for applying, in use, electromagnetic microwave radiation in a plasma cavity. The device includes a plasma cavity present within a housing, being substantially cylindrically symmetric about a first axis, and which plasma cavity includes a cylindrical wall provided with a circumferential slit. The plasma cavity is in communication, via the slit, with a first end of an elongated microwave guide having a longitudinally extending second axis. The device is in communication in use with a microwave generating device via the other end of the microwave guide, in which the electromagnetic microwave radiation being generated may include several modes, where the device can, in use, generate microwave radiation in the slit, which microwave radiation has only one electromagnetic field distribution at least in one direction perpendicularly to the propagation direction of the microwave radiation in the microwave guide.

Abstract: A one-way valve (10) is disclosed which comprises a body portion (12) defining a passage through which fluid is able to pass during use, a support member (22) disposed in the passage, a seat member (28) disposed in the passage and provided with at least one aperture (32), a shaft (24) extending between the support member (22) and the seat member (28) and a membrane (26) disposed on the shaft (24) such that the membrane (26) is rotatable relative to the shaft (24). The seat member (28) cooperates with the membrane (26) such that a first predetermined pressure differential across the membrane (26) causes the membrane to cover the at least one aperture (32) and thereby prevent fluid flow past the seat member (28), and such that a second predetermined pressure differential of opposite polarity to the first predetermined pressure differential causes the membrane (26) to not cover the at least one aperture (32) and thereby permit fluid flow past the seat member (28).

Abstract: A preform for manufacturing an optical fibre or an optical fiber, where the variation in the refractive index contrast of the preform does not exceed an absolute value of 2%, measured for a preform having a length of at least 60 cm, or the deviation of the preform in relation to the average value of the profile parameter ? does not exceed an absolute value of 0.03, measured for a preform having a length of at least 80 cm.
