摘要： A chemical analyzer providing an analysis slide positioning apparatus and method for properly aligning a test slide relative to a sample dispenser of the chemical analyzer. The slide positioning apparatus is capable of moving the slide in three different planes of movement for effecting alignment of the slide and to control fluid application thereto. The positioning apparatus includes a platform which supports the slide, a mechanism for moving the slide on the support in a first direction, and a drive mechanism for moving the platform and the slide carried thereon in second and third directions extending perpendicular to each other and to the first direction.

摘要： According to one embodiment of the present invention, a print head comprises a print head body defining an interior chamber and an orifice plate. The orifice plate has an outer surface and further defines a cleaning fluid orifice through the orifice plate for conducting a flow of a cleaning fluid through the cleaning fluid orifice and onto an outer surface of said orifice plate. The orifice plate also defines a drain orifice for conducting a flow of cleaning fluid from the surface to the interior chamber. A supply of pressurized cleaning fluid is disposed in said cavity and connected to the cleaning fluid passageway. During cleaning operations, the fluid flow system defines a flow of a cleaning fluid from the passageway and onto said outer surface. The drain orifice receives cleaning fluid from the outer surface and channels the cleaning fluid into the fluid return.

摘要： Self-cleaning printer with reverse fluid flow and ultrasonics and method of assembling the printer. The printer comprises a print head defining a plurality of ink channels therein, each ink channel terminating in an ink ejection orifice. The print head also has a surface thereon surrounding all the orifices. Contaminant may reside on the surface and also may completely or partially obstruct the orifice. Therefore, a cleaning assembly is disposed relative to the surface and/or orifice for directing a flow of fluid along the surface and/or across the orifice to clean the contaminant from the surface and/or orifice. The cleaning assembly includes a septum disposed opposite the surface or orifice for defining a gap therebetween. Presence of the septum accelerates the flow of fluid through the gap to induce a hydrodynamic shearing force in the fluid. This shearing force acts against the contaminant to clean the contaminant from the surface and/or orifice. A pump in fluid communication with the gap is also provided for pumping the fluid through the gap. As the surface and/or orifice is cleaned, the contaminant is entrained in the fluid. A filter is provided to separate the contaminant from the fluid. In addition, a valve system in fluid communication with the gap is operable to direct flow of the fluid through the gap in a first direction and then in a second direction opposite the first direction to enhance cleaning effectiveness. Moreover, an ultrasonic transducer induces pressure waves in the fluid to dislodge the contaminant and thus clean the surface and/or orifice.

摘要： A high efficiency optical mixer includes a source of focused radiant energy. The focused radiant energy is concentrated by a parabolic concentrator onto an exit port. A diffuse reflector, which can be planar or arcuate, is maintained in contact with the output port thereby minimizing optical losses and diffusely reflecting light from the concentrator. The reflected light can be transmitted, by fiber optics, to an optical system. A method is providing for concentrating focused radiant energy onto a selected area and diffusely reflecting same from that area.

摘要： There are described apparatus for collecting used test elements containing possibly hazardous liquids, and a method of collecting them. The apparatus features a container, and preferably a stacking station used with the container. The container can comprise a variety of configurations, and includes side walls, first and second end walls, access means in one of the side walls near the first end wall defining an aperture to allow test elements to feed into the container, and biasing means for biasing a test element against the first end wall or against a test element adjacent to the first end wall. A highly preferred form of the container is one in which one of the noted side walls is constructed to be a leaf spring.As to the method of collecting, it comprises the steps of a) inserting the first used test element into the container adjacent one end and under the biasing means so that a portion of the first element projects from the container; b) inserting the next used test element into the container under the first test element by inserting it under the projecting portion and pushing the first test element against the biasing means; and c) inserting successive used test elements into the container so that they each enter under the last one in, until the container is full.

The printer has a print head defining a plurality of ink channels therein, each ink channel terminating in an ink ejection orifice. The print head also has a surface thereon surrounding all the orifices. Contaminant may reside on the surface and also may completely or partially obstruct the orifice. Therefore, a cleaning assembly is disposed relative to the surface and/or orifice for directing a flow of fluid along the surface and/or across the orifice to clean the contaminant from the surface and/or orifice. The cleaning assembly includes an oscillatable septum disposed opposite the surface or orifice for defining a gap therebetween. Presence of the septum accelerates the flow of fluid through the gap to induce a hydrodynamic shearing force in the fluid. This shearing force acts against the contaminant to “sweep” the contaminant from the surface and/or orifice. Also included is an ultrasonic transducer in communication with the fluid for generating a plurality of pressure waves in the fluid for dislodging the contaminant. A pump in fluid communication with the gap is also provided for pumping the fluid through the gap. As the surface and/or orifice is cleaned, the contaminant is entrained in the fluid.
