Abstract: A viscous products pumping machine meters the volume of product that it dispenses by simultaneously displacing a proportionate amount of fluid through a separate metering circuit. The fluid of the metering circuit also serves as the medium for driving the pumping pistons of the machine, and provision is made for obtaining an accurate measurement notwithstanding any product of fluid leakage that might occur between the pistons during operation. A pneumatic logic control system governs sequencing of the machine operations, including control of a shut-off valve in the product discharge line that can be used to portion the pumped product according to the amount of fluid that has been displaced in the metering circuit.

Abstract: A liquid dispenser for dispensing liquid from an inverted bottle into a tank at times when water in the tank drops below a buoying level. A hollow annular stationary member closes off the bottle's neck and has an annular diaphragm leading to a tube with seats at its upper and lower ends. A movable member has two portions that are slidable in the said tube and are joined by a measuring portion. It seats against one seat in its upper position with the measuring portion then wholly above the tube and against the other in its lower position, with the measuring portion then wholly below the tube, and it is moved between them by the change of water level in the tank. This movement is aided with a buoying skirt having an annular chamber that is normally filled with water and drains only after falling; the same chamber helps to dispose the measured charge of the other liquid.

Abstract: A metering system is described for metering quantities of particles, such as fissile, fertile and shim particles for nuclear fuel elements. Predetermined volume discharges from three particle reservoirs are collected and two of them are weighed in comparison with a predetermined standard. A small amount of particulate material is added to each of the two weighed containers dependent upon the difference between the weight of the volumetrically dispensed particles therein and the predetermined standard. All three intermediate containers are then discharged into a volumetric chamber which is then brought to a standard volume by the addition of further particles. The resultant charge in the volumetric chamber is comprised of a fixed volume in which the weight of particles from two of the three reservoirs is standardized.

Abstract: An improvement in an apparatus for treating seeds or other particles with a liquid. The apparatus includes a receiving chamber for receiving particles and liquid, and means for conveying consecutive batches of particles and liquid to the receiving chamber. Liquid is metered in batches through a liquid metering means which includes a container and a cyclic container transport. The latter is responsive to the conveyance of batches of particles to the receiving chamber and cycles the container between a dip position in a supply of treating liquid and a dumping position in which a batch of liquid is conveyed to the receiving chamber. The transport orients the container in its dip position so as to drain the container when the level of treating liquid recedes below the container. The retention of treating liquid in the container when the apparatus is not in use is thus avoided.

The above is provided by means of a pump operated by the rise of water in the tank, operation of the pump causing a measured amount of sanitizer/deodorant to pass through a tube into the bowl through the overflow tube after the stopper ball has closed off the exit from the tank to the bowl. The metering is provided by the controlled amount the bellows is allowed to expand and compress.

Abstract: A vertical stack of tablets is disposed in a tubular container extending upwardly from an opening in the top wall of a housing. The tablets are dropped one-by-one in front of a reciprocable pusher, which is driven by a rotary impeller and is effective to eject the lowermost tablet out from under the stack and into a sump in the housing, where it may be dissolved by water in the sump. The impeller is driven by a jet of water from a nozzle which receives water under pressure from a conduit leading into the housing. Water under pressure from this same conduit operates a settable ratchet device and a jet-deflector so that, when the desired number of tablets have been dispensed, the jet is deflected and the impeller is stopped to stop the reciprocation of the tablet-dispensing pusher.

Abstract: A wetting apparatus and method for mixing water with a powdery dust generated from a foundry or other operation. In order to prevent dust from becoming airborne, and thus an environmental nuisance, it must be wetted before disposal. The wetting apparatus includes an elongated housing, a mixing screw, and a spray system in addition to inlet and outlet gates for metering the dust. The mixing screw load may be used to control water, while the weight of the dust itself may be used to meter its input into the housing. Alternatively, a moisture sensor or indicator for automatically controlling the quantities of dust and water may be used.

Abstract: A fluid metering device mixes a predetermined quantity of a first fluid with a larger quantity of second fluid supplied to the device at a higher pressure on each cycle. The pressure of the second fluid provides the force necessary to motivate a first pumping means which on movement to an `outlet` position within a housing displaces the mixed fluids on an outlet side of the first pumping means to their destination. Movement of the first pumping means actuates a second pumping means which pumps a predetermined quantity of the first fluid into the housing on each cycle. On the maximum pumping stroke of the first pumping means being reached at the `outlet` position, a passage is opened in the first pumping means which is then restored to an `inlet` position, the second fluid in the housing passing through the passage during such restoration and thus being available for dispatch on the next pumping stroke.
