Abstract: Photometric analysis apparatus in which a sample to be optically measured is stirred by a rotating magnetic stirring element within a container holding the sample. An optical path through the container and through the sample therein intersects the rotational path of the stirring element and is hence obstructed by the stirring element in one or more rotational positions. Rotation of the stirring element is controlled in a manner which stops rotation thereof in a position out of the optical path thereby allowing optical measurement of the sample material unobstructed by the stirring element.

Abstract: Combination and method for mixing a blood sample and an anticoagulant within a collection tube and for then capturing, removing and discarding the mixing element without danger of direct contact between the blood sample and the technician. The full combination includes a blood collection tube, at least one resilient end cap for the tube having a cavity which extends well beyond that tube when the cap is in place, a magnetic element slidable within the tube and receivable in the cap, and a magnet for shifting the magnetic element. After being directed into the cap following a mixing operation, the blood-covered magnetic element may be held within the cavity by finger pressure on the cap and discarded along with the cap.

Abstract: The present invention utilizes high magnetic flux materials to substantially increase the power which can be transmitted from a magnetic driver, disposed outside of a vessel containing a fluid being processed, to a magnetically responsive agitator means disposed inside the vessel. This invention now enables the agitation, e.g., mixing, blending, etc., of fluids processed in the pharmaceutical, chemical and food processing industries, where relatively high torques are encountered, by non-contaminating magnetic drive means heretofore precluded in such applications. Means for producing vibrational agitation, and for reducing wear of the internal agitator bearing are also disclosed.

Abstract: A synchronous motor is employed to orbit one end of a stirring rod the other end of which is suspended by a flexible diaphragm in a liquid filled container. The synchronous motor includes a stator connected to a source of regular alternating current and a cylindrical permanent magnet rotor. A drive plate is connected across one end of the rotor. The stirring rod is received in an eccentrically located aperture in the plate so that one end of the rod is driven in a circle. The motor is connected to a mounting plate on the cap of the container by a pair of threaded studs. Springs surround each of the studs so that the distance between the motor and the cap can be altered by screwing up or down on a pair of wing nuts received on the studs. The diaphragm acts as a fulcrum for the stirring rod so that the linear velocity of the orbiting free end of the rod can be controlled by altering the distance between the motor and the cap.

The cabinet includes drawers in which the specimens are held and includes numerous holes in these drawers and in the sides and base to permit substantially free flow of a decalcifying liquid. The edges of the top of the cabinet extend laterally outwards from the cabinet sides so as to enable the cabinet to be suspended in a container of decalcifying solution. The cabinet top provides a closure to prevent the escape of fumes and the cabinet is suspended such that a stirring magnet, for stirring the solution, can be positioned directly under the base of the cabinet.

Abstract: A method for producing plastic and liquid lubricants characterized by conducting a dispersion of the starting components, such as thickeners or reagents for the formation thereof, additives and fillers and base liquids into a vortical bed of ferromagnetic particles formed under the action of a rotating magnetic field.The proposed method makes it possible to reduce the duration of chemical reactions between the dispersed components of lubricants by thousands of times as compared to the known batch processes and by dozens of times as compared to the known continuous processes. The method provides continuous conduction of technological processes with high productivity, reduces by 10-20% specific consumption of expensive components, by 2-3 times the consumption of energy, and allows the process to be conducted at lower temperatures and pressures.

Abstract: An oscillatory mechanism, designed particularly for use in a laboratory shaker, includes a member, or a system of members, arranged to perform oscillatory movements, the transmission of power to that member or system, whereby its oscillation is caused or maintained, being by means of fluid pressure, the mechanism comprising means defining one or more chambers each having an inlet connectible to a source of pressurized fluid and an outlet through which, when open, pressurized fluid supplied to each chamber can escape; the respective chamber being expansible under the action of said pressurized fluid when each said outlet is closed; and wherein the motion of the oscillatory member or system in operation cyclically opens and closes each said chamber outlet, the consequent expansion of the respective chamber upon closure of the outlet delivering an impulse to said member or system whereby the oscillation thereof is caused or maintained.

Abstract: Apparatus for and method of preparing reference mixture gas samples for use with analytical instrumentation and small scale chemical reactions and processes, having a motor-driven magnetic stirrer with the motor and driving magnet mounted externally of the mixing chamber. Such structure together with the mass of the mixing chamber, which is large in comparison to the mass of the samples, helps to stabilize the temperature of the mixing chamber.

Abstract: A damper for use with a high pressure pumping system, such as a liquid chromatography system, which incorporates a reciprocating pump. The device is a generally enclosed canister including an internally formed flow volume. Inlet and outlet passages through the canister communicate with the flow volume, the inlet passage being connectable to receive the high pressure flow. A compressible body, e.g. of Teflon is positioned in the flow volume. The dimensions of the body are slightly smaller than those of the surrounding volume, whereby the high pressure flow passing between the inlet and outlet flows through the space between the body and the internal canister walls. The compression and decompression of the body in response to the pulsations in the flow dissipate the energy carried by the pulses, thereby damping same.
