  • Patent number: 5330625
    Abstract: There are disclosed an ISE slide element and potentiometric measurement of assaying, using a slide element that is positionally insensitive about an axis of symmetry. This is achieved by accessing one of the electrodes in the center of the slide element, and the other in an annular groove centered on the element center, both for liquid contact and electrometer contact. Preferably, electrometer contact occurs at a side of the electrode opposite to the side contacted with liquid.

  • Patent number: 5329686
    Abstract: A novel slide test element and method of making are described. Both feature a lip coined in the sidewall of a recess shaped in a frame member to hold the reaction member bearing the detecting reagents. The lip then overhangs the reaction member, once assembled. Assembly occurs by bending the frame member with the lip facing outwardly, thus forcing the lip to part a distance sufficient to allow the reaction member to be inserted. An optional stacking and fusing procedure is also described to facilitate shipment of frame members prior to assembly.

  • Patent number: 5330716
    Abstract: A pusher blade and its housing are described, in which the blade has a stiff front end for engaging slide-type test elements, and a flexible body portion and back end. The housing forces the blade to curve through an angle, preferably about 90.degree. C., to minimize the extension in one direction the blade would have if it were entirely rigid.The housing can provide for separate stacks of elements in separate environments to be engaged by the blade, since sealing means are provided for preventing substantial intermixing of the environments when the blade is activated.

  • Patent number: 5310059
    Abstract: A cassette for a photographic element of the kind used in computed radiography comprises a first cassette portion and a second cassette portion that are telescoped together during assembly to form the cassette. The first portion has a rectangular panel and edge walls extending around three side edges of the panel. The second cassette portion comprises a rectangular panel on which the photographic element is permanently secured. An edge wall is attached to one side edge only of the rectangular panel of the second cassette portion and it extends between the edge walls of the first cassette portion when the two portions are assembled together. A locking mechanism carried by the cassette portions holds them together in assembled relation but is easily released by an actuator for removing the second cassette portion and the photographic element so they can be delivered together to a computed radiography reader.

  • Patent number: 5303912
    Abstract: On a suction device (4, 5, 6, 21) for separating sheet films (3a) from a sheet-film stack (3), a thickness sensor (10, 11, 15, 17, 19) is mounted so as to be pivotable together with said suction device. The suction device (6, 21) releases the sheet film (3a) to be removed from a sheet-film stack (3) by bending its front section. The thickness sensor (10, 11, 15, 17) which has a forklike design is spring-biased to move onto the bent area of the sheet film (3a) still located on sheet-film stack (3). The thickness sensor comprises two levers (10, 11) with rollers (15, 17), one lever (11) being pivotable relative to the other lever (10). Depending on its path of pivotal movement the pivotably mounted lever (11) actuates a switch (19). If there is more than one sheet film (3a) between the rollers (15, 17) of the levers (10, 11) switch (19) is actuated which interrupts the sheet-film removal operation and causes its repetition.

  • Patent number: 5294943
    Abstract: Positioning of a scan line (L) relative to a recording medium drum (15) of a polygon printer is established by independently adjusting blocks (35, 36) mounted on a scan line generating optics module (10). The blocks (35, 36) have inverted V-notches (38) that nest in two-point tangential contact onto cylindrical surfaces of drum bearings (33, 34). X, z, .theta..sub.x and .theta..sub.z positions are set by x and z direction adjustment screws (44, 45, 49, 50) mounted on frame (11) that move against blocks (35, 36) against the bias of springs (61) and the weight of the frame (11). Clamping screws (56, 57) pass through oversized holes (58) and z direction elongated slots (59) on blocks (35, 36) to releasably lock blocks (35, 36) after adjustment. Alignment of holes (58), slots (59) and notches (38) maintains a constant angle of incidence during adjustment. A notch (41) of projection (40) of frame ( 11) engages with a pin (42) on printer body (29) to set y and .theta..sub.y positioning.

  • Patent number: 5288463
    Abstract: A containment device, such as a cuvette, for use in amplifying and detecting nucleic acid material at a contained detection site. A waste compartment provided downstream from the detection site is provided with fold lines that give the compartment a bi-stable configuration, so that it can expand to relieve back-pressure that otherwise builds up in such a containment device. Also, optimal locations of flow paths between compartments are described to minimize back-flow of upstream reagents into the feeder paths that are yet to be used by subsequent compartments.

  • Patent number: 5283195
    Abstract: An incubator useful in an analyzer, and a method for locating a slide element properly in the incubator. The incubator and the method are provided with a referencing mechanism and step, respectively, effective to push back on the datum surface or edge of a slide element that has been inserted too far into a station of the incubator, to move the portion of the slide element that produces a detectable signal, back a distance which is predetermined for that station to be the one that gives the most effective reading of the slide element.

  • Patent number: 5273717
    Abstract: A proboscis and method of use that automatically detects whether or not a disposable tip has been properly picked up. The proboscis features a probe supported on a base movable within a driven housing, a sensing flag with multiple signalling stations being fixed to the base. These allow the sensor cooperating with the flag to be fixed to the frame of an analyzer using this proboscis, rather than to be adjustably attached, so that no adjustment is needed of the sensor's position for recalibration.
