Abstract: A wellbore system includes a tubing hanger positioned within a wellhead and a Christmas tree (XT) coupled to the tubing hanger. The wellbore system also includes an annulus isolation device (AID). The AID includes a manual actuator configured to drive a wedge in a linear direction. The AID also includes a mating wedge arranged within an annulus flow path, the mating wedge configured to receive a force responsive to movement of the wedge. The AID further includes a stab coupled to the mating wedge, the stab configured to move in an axially downward direction responsive to movement of the mating wedge, the stab having a slotted portion moveable into alignment with an annulus passage to permit flow into the annulus flow path.

Abstract: The emergency shower includes a discharge outlet pivotable between a first non-use position and a second deployed position about a rotary union, for dispensing water therefrom. A ball valve is positionable between a first flow restricting position and a second flow permitting position, when the discharge outlet pivots between the first non-use and second deployed positions. A linkage system actuates ball valve movement when the discharge outlet pivots, by way of a first link pivotally coupled relative to the discharge outlet and movable therewith and a second link pivotally coupled with the ball valve and responsive to movement of the first link, the second link positions the ball valve in the first flow restricting position when the discharge outlet is in the first non-use position and commensurately moves the ball valve to the second flow permitting position when the discharge outlet pivots to the second deployed position.

Abstract: A computer-implemented method for generating a test set for testing a subject using a computer system comprising logic-based processing circuitry is provided. The method includes the step of selecting one or more features from among a plurality of features, wherein a measurable effect on the subject of each feature selected is based on a predetermined threshold. The method also includes generating one or more classes of stimuli based on the selected features. The method further includes selecting stimuli from one or more of said classes for presenting to the subject.

Abstract: The tempered portable wash unit generally includes a container having an interior for selectively receiving and retaining a select quantity of fluid. A dispenser may be coupled with the container and be in fluid communication with the fluid retaining interior, the dispenser being actuable between a first closed position restricting outflow of fluid from the container and a second open position permitting dispensing fluid from the container. A heat trace cable may couple with the container and be positioned therewith for generating variable heat along its length thereof in response to changes in localized temperatures to generally maintain the temperature of the fluid within the container within a desired threshold temperature comprising a range of 60° F. to 100° F. in ambient atmospheric temperatures as low as ?30° Fahrenheit (“F”) and in compliance with an ANSI Class 1 Div. 1 classification.

Abstract: A method of assessing hearing characteristics of a subject is provided. The method includes determining a hearing capability of the subject based on responses of the subject to a series of sounds presented to the subject. Each sound corresponds to a presence, absence or irrelevance of a predetermined plurality of features. The method further includes assigning the subject to one of a predetermined plurality of classes based upon the responses of the subject, each of the plurality of classes being derived from hearing tests performed on a plurality of other subjects.

Abstract: An exhaust component is provided including an inlet portion for accepting an exhaust stream entering therein from an exhaust system, two or more separator components fixed to the inlet portion for separating the exhaust stream into two or more streams at the point of egress from the inlet portion, two or more chambers fixed to the separator components, the chambers for muffling sound of the exhaust stream, two or more collector components fixed to the chambers opposite the separator components for collecting the separated exhaust streams upon egress from the chambers, and one or more outlet portions fixed to the collector components at the end opposite the chambers for carrying separated or merged exhaust streams out of the exhaust component.

Abstract: Soda lime silica float glass in ribbon form is produced at reduced cost by replacing at least part of the soda ash conventionally used as a source of sodium fluxing agent by calcined trona ore. The invention may use calcined trona ore from the deposits in the Green River Valley area of Wyoming, USA.
