    Abstract: The digital output of a spectrophotometer is multiplied by a factor to correct for drift in the absorbence of a sample standard. The value of the factor is determined by comparing a standard sample which has undergone drift against a preset value stored in the drift correction circuit. Circuitry is provided to accumulate the amount of drift correction and sound an alarm if it exceeds a predetermined value.

    Abstract: A method and apparatus for providing patient record information on a specimen tube containing a specimen taken from the patient and for reading the information therefrom when the analysis of the specimen has taken place. A typewriter is used in conjunction with encoding and writing circuits to cause a magnetic recording head to provide binary information on an annular magnetic band on the specimen tube. When the analysis of the tube contents have taken place, the tube is placed in a rotating reading device and a magnetic reading head picks up the coded information and through decoding circuitry either prints out the information and/or stores it in a computer along with the results of the specimen analysis.

    Abstract: AN APPARATUS FOR DETERMINING THE COAGULATION TIME OF BLOOD AND OTHER LIQUIDS WHICH HAS A MOTOR DRIVEN ROTATING STIRRER THAT IS MOUNTED FOR VERTICAL MOVEMENT ON A BASE BELOW WHICH IS MOUNTED A ROTATABLE INDEXING SUPPORT MEMBER BEARING LIQUID SAMPLES. A MANUALLY OPERABLE RACK IS USED TO INSERT THE STIRRER IN T HE C ONTAINERS AND TO START THE MOTOR TO ROTATE THE STIRRER. A SLIP SWITCH IS USED TO BREAK THE CIRCUIT WHEN THE STIRRER ENCOUNTERS RESISTANCE CAUSED BY THE COAGULATION. THE TIME FOR COAGULATION IS READ DIRECTLY OFF A COUNTER ATTACHED TO THE MOTOR.

    Abstract: Apparatus for repeatedly metering and dispensing, by means of a piston pump, predetermined quantities of liquid via a switching valve to which are connected inlet and outlet conduits for the liquid. The pump and the valve are actuated in timed relation by a drive mechanism powered by an electric motor which is controlled by selectively operable means that automatically cut off the motor supply once the piston has completed a stroke. There are also provided means for varying the length of the piston stroke to adjust the volume of said quantities and means for displaying to the outside a number indicative of this volume.

    Abstract: The present invention relates to optical instruments, such as photometers including spectrophotometers, and relates more particularly to a light-shifting device of light refracting type for receiving a beam of light used in such instruments and shifting it into one or the other of two parallel paths. An optical instrument having a light source, means comprising a diaphragm for directing a collimated beam of light from the light source in a path along an optical axis, light-refracting means disposed in the path for receiving the light beam and shifting the beam from its incident path thereto alternately to each of two offset parallel paths which are parallel to the incident path, and means for supporting, in the offset parallel paths, sample and comparison objects to be scanned by the shifted light beam in those paths.

    Abstract: A mechanical counter capable of showing values changing continuously and at a high rate of speed, which comprises a series of numbered drums containing e.g. six groups of 10 figures moving angularly in front of a reading window. Each drum after the first has a toothed internal gear, and each drum preceding the last has a pair of circular cams for causing periodic movement of the subsequent drum and then locking it between movement periods. This transfer movement is effected by one of a series of gear means, mounted such that each gear means consists of a first gear continuously engaged with the toothed rim of a given drum, and second and third gears each having a pitch twice that of said first gear and having their teeth alternately aligned with teeth of said first gear, so that the second and third gears are alternately moved and locked by said pair of cams. Each cam has e.g. three arcuate projections, each projection of one cam being opposite an empty space of the other cam.
