Abstract: A base for use with scaffolding. The base includes side support members and cross members. The side support members have scaffold receiving members provided at ends thereof. The cross members extend between the side support members and are rotatably mounted to the side support members. Wheels are mounted to the cross members. As the cross members are rotated from a first position to a second position, the wheels are moved from an initial position in which the wheels are spaced from a ground or floor surface to a second position in which the wheels are positioned in engagement with the ground or floor surface.

Abstract: A cable management system includes multiple cables, each having a unique identifier associated therewith and each including first and second barcodes including the unique identifier, the first barcode located proximate a first end of the cable, the second barcode located proximate a second end of the cable. The system also includes a barcode scanner to scan barcodes of the cables, the barcode scanner including a clip to receive one of the cables. The system also includes a mobile computing device having a processor, data storage medium, communication unit, and user interface including a display. The mobile computing device is configured to receive via the user interface first end location information for a first cable, receive from the barcode scanner the first barcode of the first cable, and save and display the first end location information in association with the unique identifier of the first cable included in the first barcode.

Abstract: A medical device includes an elongate body, an expandable treatment element, a plurality of flexible shafts, and a plurality of electrodes. The elongate body has a proximal portion and a distal portion opposite the proximal portion. The expandable treatment element is coupled to the elongate body to receive a fluid and, in some examples, is anchored to the plurality of flexible shafts with a plurality of retention elements. In some examples, each flexible shaft of the plurality of flexible shafts has a braided configuration. Each electrode of the plurality of electrodes is attached and electrically coupled to a respective flexible shaft of the plurality of flexible shafts.

Abstract: Disclosed is a laser (10) comprising a lasing cavity with a lasing medium and primary optical feedback means in the form of a facet (17) at either end of the cavity, the laser cavity defining a longitudinally extending optical path; and secondary optical feedback means formed by a plurality of refractive index perturbations (16, 22) in the laser cavity, each perturbation defining two interfaces (20, 21); characterized in that, for at least one perturbation, only one of the two interfaces contributes to optical feedback along the optical path. The present invention relaxes the lithographic tolerances for making single longitudinal mode devices and improves performance characteristics.

Abstract: The present invention relates in general to semiconductor light emitting devices and in particular to methods of altering the spatial emission patterns of such devices. A known problem with these prior art light emitting devices (and laser diodes in general) is that their far-field emission patterns are elliptical and astigmatic in nature. The present invention addresses this problem by refractive index perurbations in the semiconductor device aligned in a direction substantially transverse to the light emission direction to achieve a desired spatial distribution of the emission.

Abstract: A prior art quench-type, direct contact, heat exchanger device used especially between catalyst beds in a reactor vessel, is modified to include a liquid-liquid pre-mixing baffle upstream of a gas-liquid heat exchange section. The pre-mixing reduces the fluid non-homogeneity experienced by current quench type heat exchangers in certain applications. The baffle not only pre-mixes non-homogeneous fluid stream portions, but provides a pair of liquid streams which impinge within the prior art heat exchange device. The pre-mixing and impingement improves the heat transfer process within the prior art device. The relatively low velocity liquid flowrate upon which the baffle operates minimizes any added pressure loss. The pre-mixing baffles also provide some acceleration and increased contact with the quench gas stream to further improve heat transfer with only a moderate effect upon the overall pressure drop across the device.

Abstract: Selenium exists in oil refinery stripped sour water as selenocyanate and can be effectively removed using an acrylic, strong base, anion exchange column or stannous chloride. The acrylic, strong base, anion exchange column can also be employed to remove arsenic, iron, and vanadium from an aqueous fluid.

Abstract: A method for fracturing formations near a shallow horizontal well notches a wellbore at orientations such that later applied hydraulic pressure generates fractures only in preferred directions.

Abstract: An integrated system of non-condensable gas (NCG) and condensate treatment allows geothermal power plant condensate and non-condensable gas effluent streams containing H.sub.2 S and ammonia to be commercially useful for more than for cooling tower makeup. In the preferred embodiment, the pH of the condensate is increased by adding ammonia and the pH increased stream is contacted with NCG to scrub and oxidize the H.sub.2 S constituent of the NCG. By reducing the pH, the condensate or aqueous stream mixture can also be used to further transfer ammonia from the non-condensable gas stream to the aqueous stream, enriching the stream for use as a fertilizer/irrigation water mixture. If other commercial uses are desired for the mixture and/or oxidized NCG streams, they can be resin treated to remove the ammonia constituent. With the ammonia and H.sub.2 S constituents decreased, the condensate may be used for a variety of applications and the NCG can be injected or used as a commercial feed stream.
