摘要:
A gas vent valve assembly may be attached or incorporated to a disposable fluid transfer set used with a fluid warmer to administer an infusate to a patient. The gas vent valve assembly has a housing having a fluid inlet, a gas outlet and a fluid outlet. The gas outlet is located at the top of the housing while the fluid outlet is located at the bottom of the housing. The fluid inlet is located at a side lower portion of the housing. Inside the housing is an actuator float that has an upper seal and a lower seal. The dimension of the float relative to the chamber of the housing is such that the float is freely movable within the housing to an upper position whereby its upper seal closes the gas outlet while the fluid outlet is opened, and to a lower position whereby its lower seal closes the fluid outlet and the gas outlet is opened. The movement of the float is dependent on the respective amounts of air and fluid in the housing, and the buoyancy of the float relative to the fluid in the housing. When a predetermined volume of air gets inside the housing, the float sinks to its lower position to close the fluid outlet and open the gas outlet, so that the air inside the housing is vented to atmosphere while fluid is prevented from being output to the patient. When the amount of gas in the chamber has been reduced to a given volume, with a corresponding increase in the amount of fluid in the housing, the float is raised to open the fluid outlet, thereby enabling the fluid inside the housing to be output to the patient. At that time, the gas outlet is shut to prevent any reverse inflow of air into the housing.

A connector assembly for a heat exchanger has a fitting and a mount to which the fitting couples. The fitting has an elongate body having a proximal portion and a distal portion. At the proximal portion there is a crossbar, and at the distal portion there are an inlet and an outlet that protrude away from the body. Two wings extend from the body in a direction opposite to that of the inlet and outlet. There is formed on each of the wings a locking protrusion. The mount has a top portion where there is a groove dimensioned to accept the crossbar of the fitting. A longitudinal channel is formed orthogonal to the groove in the mount. Two sidewalls extend from the mount each for accepting a corresponding one of the wings, when the fitting is coupled to the mount. Apertures are provided at the sidewalls to engage the protrusion at the wings so that, once the fitting is coupled to the mount, it is secured thereto, until a force is exerted to compress the wings towards each other to disengage the protrusions from the apertures. To couple the fitting to the mount, a user first positions the crossbar of the fitting onto the groove of the mount, with the body of the fitting at an angle relative to the mount. With the crossbar resting on the groove, a pivot point is established between the fitting and the mount, so that the body of the fitting can be pivotally positioned within the channel of the mount. At that time the inlet and outlet of the fitting are mated to an output port and an input port, respectively, of the mount; and the protrusions at the wings of the fitting are engaged to the apertures at the sidewalls of the mount. An infusate line and a heat exchanger are connected to the proximal end and distal end, respectively, of the fitting.

An internally insulated exhaust aftertreatment device with a converter body, an end cone assembly and a sealing device inserted in an annular area between the external shell and the substrate of the converter body. The sealing device is sealingly engaged between an inner end cone and the insulating material. The sealing device comprises a wire-mesh ring-shaped device conformable to the annulus between the substrate and the shell, and may have a substantially round cross-sectional area, a C-shaped cross-sectional area, or an L-shaped cross-sectional area.

In one embodiment, a method for duplex scanning includes: illuminating a first side of an object with light of a first color from a group of colors; sensing the first color light reflected from the first side; illuminating a second side of the object opposite the first side with light of a second color from the group of colors simultaneously with the act of illuminating the first side with the first color light; and sensing the second color light reflected from the second side. In another embodiment, a duplex scanning method includes simultaneously illuminating each side of a document sequentially with each of multiple colors of light but in different color sequences for each side of the document so that the same color light does not illuminate both sides of the document at the same time.

A method and system for matching a knowledge worker to a selecting entity's needs according to a system of codes corresponding to pre-defined rules of engagement. The rules of engagement include, but are not limited to, experience levels, salary, geographic location, job starting date and duration, and industry sector. If a search of knowledge workers fails to match an available worker with a job need of the selecting entity, the selecting entity posts a job posting on a website maintained by a third party administrator who maintains webpages that are accessible only to screened job applicants.

A system including a user computer is configured to generate an electronic document file, and an imaging apparatus is configured to form mirror images on a side of a transparency media in correspondence to the electronic document file. The system also includes an overhead projector configured to support the transparency media with the imaged side in contact with the overhead projector, and to project the mirror images in proper viewing orientation onto a surface. A method of imaging transparency sheet media includes detecting a transparency media designation associated with an electronic document file, and determining a mirror imaging status in response to detecting the transparency media designation. The method further includes deriving an electronic mirror image corresponding to the electronic document file in accordance with the status, and forming an image on a sheet of transparency sheet media in accordance with the electronic mirror image.
