    Abstract: A guide rail or track system for guiding test tube holders or racks from one station to another, e.g., in a mono-channel analyzer, for presenting test tubes in such holders in sequence to one or more servicing operations at a plurality of stations. The rail system may comprise a main linear guide rail along which a holder having a row of test tubes supported therein is adapted to be moved longitudinally stepwise to present each test tube in the holder in sequence to a given station, or a given position therein, where an operation is to be carried out with respect to each test tube as it is presented in the station. Arranged at right angles to the main rail, one or more branch rails leading to or from other service stations are provided at spaced intervals and the main rail at each juncture or intersection of these rails is constructed to allow a lateral shift of the holder (also specially constructed to allow such shift) to or from the main rail respectively from or to the branch rail along which the holder moves laterally, i.e., the lengthwise dimension of the holder extends across the branch rail at right angles to it as the test tube holder moves along the branch rail, which may terminate at a junction or intersection with another or subsidiary rail or guideway along which the holder moves longitudinally in a direction parallel to the main rail. Means is provided for moving the holder along the main rail and means is provided at the junction of a branch rail with an intersecting rail such as the main rail, for laterally shifting the holder from the junction.

    Abstract: An incubation apparatus for use in automated biochemical analyzer system which comprises a block of thermoconductive material having rows of wells for the reception of sample carriers to be incubated with temperature control attached to the block; the block resting with well openings facing downward upon a pair of insulating plates so arranged that by movement of one of the plates, a row of wells is exposed so as to allow a number of sample carriers, equivalent in number to the number of wells in a row, to be loaded into that row of wells, the sample carriers being in alignment with and directly below the row of wells; and a means for lifting the sample carriers up into the wells or lowering sample carriers down out of the wells.

    Abstract: 1487775 Absorbance change measurement MICROMEDIC SYSTEMS Inc 23 Dec 1974 [19 Feb 1974] 55541/74 Heading G1A The change in absorbance per unit time of sample is measured by periodically developing digital signals, each comprising a pulse train having a length proportional to the logarithm of the ratio of the intensities of radiation passed through the sample and a standard, respectively, and utilizing counting apparatus to compare the numbers of pulses generated in two consecutive time intervals forming two sequential digital signals. Photo-electric absorption measurement system, Fig. 1. A wide band optical source 104 illuminates a mono-chromator section 200, including inlet and outlet apertures 215, 216 and a diffraction grating 201. The selected wavelength is displayed on monitor 800. When red, infrared or ultraviolet light is used, an extra filter appropriate to the radiation is introduced by slide 205, so as to prevent stray or second order diffraction light reaching the sample. The sample and reference cuvette section 300 may be supplied intermittently or continuously with fluids. The optical beam is switched between illumination of the sample and the reference by a pair of quartz, plastics or glass cross-mounted elongated prismatic elements 401, 402. A synchronization 600 coupled to sense which of the sample and reference is being illuminated controls delivery of the signal developed by photo-multiplier 501 sensing transmitted beam to the evaluation circuit 700. A prism 52 directs the alternate beams on to the detector 501. Detector and counting circuit, Fig. 2. A clock 806 periodically stimulates generation of an exponentially decaying signal from circuit 808. Applied to inputs 810, 812 are voltages representing the detector output for the reference and sample transmissions respectively. As the exponential signal falls below these negative voltage levels, as sensed by comparators 802, 804, a constant height pulse of duration logarithmically proportional to the difference between the voltages is produced from Exclusive -OR gate 818. This is converted into a digital signal i.e. a pulse train by oscillator 902 and gate 904. Depending on which is greater of the sample and reference voltages, up or down counting is initiated in counters 912, 914. Except for the first timing interval, the counters operate as follows:- counter 912 counts the currently supplied pulses in a digital signal and at the end of the interval transfers this number to counter 914, after which it is cleared; counter 914 counts in the opposite direction to counter 912 and so effectively subtracts the current member from the number for the previous digital signal, timing interval; thereby at the end of the timing interval, having accumulated therein an absorbance difference representative number. If there is a difference, this is printed out at 916. Other parts of Fig. 2 circuit are for scaling so that the printer provides the required units. Variations on the repetition rate and length of timing intervals are possible. Counters 912, 914 may be arranged to subtract alternately, the other counter storing the number for the current digital signal.

    Abstract: Response time for the adjustment of temperature for spectrophotometric cells is reduced by direct temperature control of the cell. A spectrophotometric temperature control (10) comprises a cell (12) with two light transmission chambers (14) which form receptacles for reference and sample materials. A thermistor (16) is placed in a hole (18) in the cell to be in physical contact with the cell and is placed between two thermoelectric cells (28, 30) with thermal masses (32, 34) permitting stable heating or cooling in response to a signal from an electronic control circuit with two channels. One channel senses temperature changes from the thermistor (16) while a second channel senses ambient temperature changes from a second thermistor (36) placed in the photomultiplier tube compartment.

    Abstract: The invention is concerned with a novel container for receiving a liquid material having a fitting at one end adapted to provide a discharge port for the liquid within the container and having at its other end a plunger or piston adapted to be moved within the inside wall of the container to discharge one or more predetermined "aliquots" or "doses" of liquid from the container through the port. The invention also comprises a novel device adapted to receive a liquid-containing cartridge or package of the type just mentioned and having means for coacting with the package to move the plunger within the container during dose-dispensing or -discharge in such a manner as to gradually accelerate movement of the plunger from a position of rest within the container through a maximum rate of motion and then gradually decelerate the motion of the plunger to a final position at the end of the dose-discharge. The device also comprises means for accurately predetermining or "measuring" the amount of liquid discharged during each individual movement of the plunger. The device may comprise means for repeatedly actuating the piston with an accelerating-decelerating movement to discharge a plurality of measured samples repeatedly under non-spurt and non-splash conditions.
