Abstract: It is often necessary to manufacture casting masses out of several components which must be homogeneously mixed in a specific ratio. It can thereby happen that such casting masses harden so quickly that they must be processed in the shortest time possible in order not to react with one another or harden already in the mixing area or in the pipelines and thus result in the possible destruction of the device. The components are in the arrangement of the invention each moved by a pump out of the respective storage tanks into a synchronous dosing mechanism which consists of a dosing chamber for each component, from where the respective now dosed amount of each component is moved with the help of a dosing piston into a flow mixer, with the dosing pistons being thereby mechanically connected and operated by a common drive, and the flow mixer moving the now ready casting mass directly into a mold. The mixing ratios can in this manner be well maintained.

Abstract: A trigger actuated dispenser pump for dispensing product from a container, in which a multi-function piston member has a primary piston reciprocable in a pump chamber and a secondary piston reciprocable in an outlet chamber. The primary piston draws product from the container, pressurizes it and pumps it into the outlet chamber. The secondary piston functions to reduce pressure in the outlet chamber during initial movement of the pump, tending to promote flow from the pump chamber into the outlet chamber. A flow restrictor is positioned in the pump chamber and is operative to limit reverse flow from the pump flow into the container. An outlet valve in the outlet chamber functions to prevent dribbling of product at the end of a discharge or pressure stroke, remaining closed when the pressure of product in the outlet chamber is below a predetermined minimum, and a positive shut-off valve may be positioned in the outlet chamber for precluding flow from the pump when it is an at-rest position.

A control device controls displacement of the syringe pump and the piston of the syringe pump, actuation of the supply system and the drainage system, and reads measurement output signals of the weigher.

Abstract: In a flow rate control apparatus, pressure of a primary, or controlled, liquid is reduced without application of shear forces thereto. Each of first and second piston and cylinder assemblies has a first port on one side of the piston and a second port on the other side. A secondary fluid path between the two second ports contains a controlling fluid directed through a pressure reducing valve. The rate of flow of the primary fluid from the discharge cylinder is controlled by the rate of flow of the secondary fluid through the pressure reducing valve. A four way valve couples the controlled liquid at relatively high pressure through the first port in a first cylinder, and the controlled liquid is discharged at relatively low pressure from the first port in the second cylinder. The first and second pistons are rigidly connected to assure synchronized motion and accurate metering of the controlled liquid and to provide for driving of both pistons in response to input pressure of the controlled liquid.

Abstract: An apparatus for forming and dispensing portions of soap foam or lather is provided with a double-acting compressed air membrane pump for generating compressed air and with a soap solution dosing pump. Both pumps are operated by means of a single lever which need only be pressed in a single direction, the return motion to the initial position being effected by a return spring. The forward actuation of the lever causes soap foam or lather to be formed in a mixing chamber. The return motion of the lever dispenses a dose of soap foam or lather through a dispensing aperture. In order to obtain a double-acting pump action of the membrane of the membrane pump, inlet valves and and outlet valves are employed. One of the outlet valves assists in the generation of the soap foam in the mixing chamber. The other outlet valve then assists in ejecting a portion of the soap foam through the dispensing aperture during the return motion of the lever.

Abstract: A hopper is supported above a supporting surface and includes a pair of spaced apart apertures in the base. A metering and dispensing plate is rotatable from one position to another below the base and includes a pair of spaced apart metering apertures each of which aligns alternatively with the apertures in the base of the hopper as the plate is moved from one position to the other. When one metering aperture is aligned with one aperture in the base, the other metering aperture is aligned with a dispensing aperture in a base plate below the metering and dispensing plate. The material from the hopper flows into the aligned metering aperture and the material already in the other metering aperture flows out through the dispensing aperture. The metering apertures are adjustable in volume by rotating the handle extending from the plate which is also used to partially rotate the plate from side to side.
