Embodies many features representing marked advances. Rugged in construction, simple and convenient to operate, it may be used for routine laboratory work or for research.\nConstant speeds are obtainable by an induction motor drive working from 110 volts, 60 cycle A.C. A gear box in the base permits four speed changes: (1) 2.2 cm. per minutes, (2) 11.0 cm. per minute, (3) 54 cm. per minute, (4) 270 cm. per minute. A 100 vibration per second tuning fork may be conveniently used with the highest speed; one second intervals, with the lowest speed.\nThe aluminum chart drum, 150 mm. high, and 165 mm. in diameter is adjustable in height over a range of 175 mm.

The writing pressure is obtained from the weight of the writing lever itself since it is pivoted at the axis of rotation. The writing lever is pivoted so that it is free to move toward or away from the writing surface, and the axis of this pivot is inclined toward the writing surface. This causes a small fraction of the weight of the writing lever to exert pressure against the writing surface. Such pressure is constant within the limit of the excursion.\nThis method of writing eliminates all special tension adjusting accessories because there is no spring tension to be carefully adjusted and the exact position of the writing lever relative to the kymograph drum does not have to be controlled.\nA 70-320\nPEN STARTING\na.\tPill reservoir two-thirds full of ink, using the dropper furnished.\nb.\tPress writing tip through rubber cap of the pen starter.

The development of gravity writing, whereby writing points are held against the drum by gravity, which is constant, rather than by spring tension, which varies with pen movement, made possible the successful development of Bird Ink Writing Levers.\nThe pens, of corrosion-proof, stainless steel, are inserted into the pivot clamp of the recording instrument at the axis, beneath which an ink reservoir is suspended. An offshoot of the pen dips into the reservoir. The ink flows from the reservoir and through the pen by capillarity, making an easily photographed line comparable to the best tracings. The weight of the pen filled with ink is constant and is so slight that loss in sensitivity is negligible. Friction is less than when writing on smoked drums.\nIf pens are cleaned within a few hours after use, clogging is negligible. A pen cleaner and starter are supplied with each pen.\nA 12-760\nCEMENT\u2014Duco, In Collapsible Tubes.

An improved mercury manometer consisting of a glass U-tube, carefully selected for uniform inside diameter, mounted on a Monel metal backing with an integrally mounted support rod. The U-tube is easily removed for cleaning.\nThe manometer is so designed that it may be mounted at the same level as the kymograph drum. The stylus falls against the drum by gravity rather than spring tension and is so arranged that it is several centimeters below the mercury level. With this arrangement, the float and \u201cwire\u201d tend to remain centered rather than to fall to one side as with the conventional type manometer.\nThe float is concave to fit the mercury meniscus. The \u201cwire\u201d is stainless steel tubing, thus having greater rigidity for the same weight than solid wire. It protrudes through the bottom of the float several millimeters into the mercury. By this means the center of gravity is lowered, and the float tends to remain perfectly centered over the mercury.\nOverall length is 32 cm. Pressures of over 250 mm. may be recorded without danger.

Designed to eliminate the tedious procedure of obtaining the accurate count of each classification by making it a mechanical operation. It does away with the necessity of figuring the percentages of each type of blood cell. A key representing each type of blood cell operates a counting unit. Each time a key is pressed one count is recorded in the counting unit controlled by that key. When a total of 100 counts have been recorded the machine automatically locks, and the percentage of each of the several types of blood cells counted is plainly visible in the window of each counting unit. Machines contain two resets. One on the left resets the tabulating units, the one on the right resets the totalizer\nlock unit. Closer percentages than a total of 100 can easily be made after the first 100 counts by resetting the totalizer lock unit to zero and proceed with the sound count of 100. Since a total of 200 counts have been made the percentages are obtained by dividing the total of counts in each window of the tabulating units by two. Red and white corpuscle counts may be made by clamping down the totalizer operating bar. The totalizer mechanism is then out of operation. Any two or more keys of the machine may be used for this work. Small model containing five tabulating units and a totalizer unit.

It retains the original features of the older models which met with favorable comment.\nThe extraction chamber has a volume of 50 ml., with graduations at % ml., 2 ml., and at 50 ml. At the top is a sample cup graduated to 6 ml. and communicating with the extraction chamber through a stopcock.\nThe extraction chamber is mounted in a cage, directly driven by a universal motor of the highest grade. The upper and lower positions of the leveling bulb are adjustable to suit the user. Complete, glare free illumination of the manometer is provided.\nThe manometer and extraction chamber are certified for accuracy. The Van Slyke specifications are rigidly adhered to.\nThe wash bottle is mounted with special care and cannot be tipped over, and the glass tips of the suction and distilled water lines are held in convenient receptacles. The support is of selected oak, assembled in a workmanlike manner, and finished with durable clear lacquer. The panel which carries the manometer is removable from the support so that it can be used as a protection to the manometer for shipment.\nIn addition to these more or less standard features a tachometer is provided on the drive motor which indicates the shaking rate, an exclusive feature on the apparatus. The tachometer instrument is especially designed for direct use on the motor shaft at high speed. The tachometer is of the magnetic type, individually calibrated for accuracy. The motor shaft itself carries the magnet so that the motor bearings become the tachometer magnet bearings.\nFurnished complete on stand with extraction chamber of highest accuracy enclosed in a water jacket; a thermometer; a manometer; leveling bulb, 250 ml.; adjustable leveling bulb support; direct motor drive with worm-drive reducer; aspirator and waste bottles.
