    Abstract: The instant invention relates to an apparatus for metering at least two flowable reaction components, such as polyurethane-forming components, in a predetermined ratio into a mixing chamber. The apparatus broadly comprises a metering unit for each component, which is made up of a piston and cylinder, a feed pipe leading from a storage container into the cylinder, a delivery pipe leading from the cylinder to the mixing chamber and optionally a return pipe, and a drive unit. Each drive unit is in the form of an electro-hydraulic linear amplifier which comprises a stepping motor for a control mechanism which is coupled to a hydraulic piston and cylinder, wherein the drive unit is capable of driving the metering piston. Control electronics are provided for controlling the metering units. The controls comprise at least one adjustable control frequency generator for generating signals to be fed to the electro-hydraulic linear amplifiers to control the movements of the metering pistons. A first signal path is provided for conducting signals to at least one of the electro-hydraulic linear amplifiers from a control frequency generator and a second signal path is provided for conducting the control frequency generator signals to all other electro-hydraulic linear amplifiers via an adjustable frequency reducer.

    Abstract: A system and method is disclosed for continuously producing and dispensing foam material including storage containers with respective delivery lines for delivering, via separate motor driven pumps, a foaming agent solution and curable synthetic resinous material to a mixing gun. An air compressor supplies compressed air which is first heated and then directed to the mixing gun wherein the components are mixed in the proper proportions to produce and dispense foam to the point of placement. The system includes an electric motor which conjointly drives the separate pumps which supply the constituent materials to the mixing gun under predetermined constant pressures and continuous flow conditions so as to produce a homogeneous and continuous foam product of desired density generally free of streaks and inconsistencies. In one embodiment, pumping of the materials is accomplished by conjointly driven diaphragm piston-type pumps connected to a gear box of desired gear ratio and driven by the electric motor in a manner to provide high torque with relatively low motor power. In a second embodiment, pumping is accomplished by conjointly driven gear pumps in which at least one gear is of a type having internal teeth for pumping.

    Abstract: There is disclosed a novel dispensing unit and system for the controlled, metered dispensing of one or more liquid products. The unit which serves to provide an important part of the system is designed for use with an arrangement wherein pressurized liquid products are delivered to the unit for controlled, metered dispensing. The unit is characterized primarily by the employment of metering chambers defined partially by flexible diaphragms. In conjunction with each said chamber, there are provided an inlet and outlet passage arrangement and a valve arrangement for controlling the supply and discharge of liquid product from said metering chamber. The unit includes a selectively operable control arrangement provided for opening and closing the valving arrangement, and also alternately pressurizing and venting the metering chamber diaphram with respect to a pressurized medium. When pressurized the metering chamber diaphragm will move relative to the remainder of the metering chamber to expel a predetermined quantity of liquid product from said chamber. The liquid product thus expelled will correspondingly replace liquid product in the discharge passage of the unit and will ultimately result in dispensing of a similar quantity of product from the dispensing head or outlet ports for the unit.

    Abstract: The apparatus comprises a turntable carrying, in a circular array centered on a central rotational axis of the turntable, a plurality of vials extending below the underside of the turntable. A stepper motor imparts stepwise rotational motion to the turntable so that during dwell periods of the turntable, specimens in the vials can be investigated optically.Air in a space below the turntable and bounded laterally and at the bottom by an enclosure is circulated by a rotating vane, and a thermistor, responsive to the temperature in the region of the vials, controls a heater in the space below the turntable so as to maintain the temperature of the vials substantially at a predetermined value.In order to dispense liquids into the vessels at predetermined temperatures, the apparatus additionally includes a liquid dispenser mounted adjacent the turntable and comprising a tubular body with an electric heating coil and a dispensing device which dispenses liquid from the outlet of the tubular body in predetermined quantities, the heating coil being supplied with the necessary quantity of power to maintain the temperature of the dispensed liquid substantially at a predetermined value.Preferably, the apparatus is used for analysing blood specimens.

    Abstract: A plug type valve for use in handling the flow of particulate catalyst is disclosed. In catalytic cracking equipment, it is necessary to regenerate the catalyst. The flow of catalyst to and from the regenerator must be controlled. A plug valve is disclosed for control of the flow of catalyst and the valve includes a tapered spear-like plug formed of a sacrificial material mounted on a stem. The stem is protected against the abrasive action of the particulate catalyst by means of a cylindrical spaced shield below the valve element and a circular jet of steam ejected downwardly below the shield and parallel to the stem.

    Abstract: A liquid chemical storage and dispensing unit is disclosed in which a mobile cart supports upper and lower groups of pressure sealable storage tanks containing liquid chemicals. Conduits couple a pressure distributing gas manifold to the upper tanks. Tank pairs comprising one tank each of the upper and lower groups are serially coupled by conduits of equal effective internal dimension extending between an open end within a lower region of the upper tanks and inlet fittings on the lower tanks. An open end in the lower tanks communicates liquid chemical therein via conduits of equal effective internal dimension to a nozzle receiving liquid chemical collecting manifold. A plurality of tank pairs are thereby coupled in parallel between the gas manifold and the liquid chemical collecting manifold providing simultaneous emptying of the tank pairs at an enhanced potential liquid chemical flow rate. In operation, tanks are individually filled with liquid chemical and the cart is transported to a point of use. A gas pressure source coupled to the gas manifold forces liquid chemical through the upper tanks to the lower tanks and from the lower tanks to an outlet coupled to the liquid chemical collecting manifold. Thereafter the pressurized tanks successively feed chemical on demand to coupled sprayers until the last tank is empty.
