Abstract: A solid product static brake (10) is provided which is employed in cast solid chemical block dispensing systems for slowing a generally downward gravitationally driven movement of the solid chemical block when placed or installed in a chemical dispenser. The brake provides the ability to prevent the destruction of the cast solid during installation due to mechanical shock. The static brake comprises a horizontal base frame (12), and a plurality of rigid blade members (18) extending from the base frame in a generally perpendicular direction. When a new solid block is installed, the blade members contact and slow the solid block as it falls into the dispenser.

The dispenser (10) is comprised of a container (11) and lid (12), the dispenser containing a solid detergent composition (13). A slot (23) in a side wall (17) and baffle (26) allow for controlled drainage of the detergent solution. The lid (12) has a plurality of openings (18) through which water from the dishwashing machine enters, so as to dissolve the solid detergent (13). The dispenser (10) is positioned within the washing chamber (20) of a dishwashing machine (19).

Abstract: A controllable dispenser which dispenses an aqueous solution of a soluble substance. The dispenser has an inlet to accept a supply of water and an outlet to discharge the solution. The dispenser includes a container having a chamber, where the soluble substance is placed, and a passage surrounding the chamber. The chamber is longitudinally in line with the inlet and outlet. The water entering the device is able to flow through both the chamber and the passage. The fluid flowing through the passage functions as a carrier of the solution to the outlet. The chamber is defined at both ends by an orifice. Various chambers may be used, each having a different diameter and different size orifices, one allowing a greater rate of flow than another, thereby increasing the level of concentration or the rate of solubility. The device is preferably constructed of a transparent material which enables the user to observe the amount of soluble substance remaining in the chamber.

Abstract: A process and apparatus for extracting ingredient substances from natural products by means of a pressurized fluid, particularly for decaffeinating tea leaves by means of carbon dioxide, wherein the ingredient substances are bound by an adsorbent, preferably activated carbon. The fluid is conducted through a product layer, the thickness of which in flow direction is small in comparision with that transversely of the flow direction and the fluid is passed through the product layer with changing, especially increasing, velocity. The apparatus includes a cylindrical high-pressure vessel with annular cylindrical baskets for accommodating the natural product and/or the adsorbent, and the gas flows from a cylindrical outer range to a cylindrical inner range. The time required for the treatment of leafy natural product is reduced, the flow paths of the fluid are shortened, thus diminishing the risk of clogging, and the fluid flow velocity is reduced.

Abstract: Method and apparatus for dispensing detergent from within a container comprises directing a water spray transversely of the container vertical orientation to dissolve and remove detergent in solution from the container.

The volume of solution dispensed is varied at times when the liquid pressure is varying by selection of an aperture from a plurality of apertures at varying axial positions, for placing the interior of the pipeline in communication with the interior of the enclosure above the solution level, at times when the level drops axially to the selected aperture; or, at time when the liquid pressure is substantially constant, by adjustment of the amount of liquid permitted to enter the device.

Abstract: A fertilizer applicator for solid fertilizer is provided, and is inserted into a sprinkler line system. The applicator comprises a container component which encloses and suspends a fertilizer holder component and spaces the two conponents to define a water pressurization chamber therebetween. Water is fed from the container through the pressurization chamber and into the bottom of the fertilizer container where it dissolves some of the fertilizer and forms a leached, concentrated solution. This leached solution rises through the fertilizer and into overflow tubes where it drains downwardly through the bottom of the fertilizer holder. The concentrated solution is then diluted with water draining from the bottom of the water pressurization chamber, and the diluted solution of fertilizer is passed into the sprinkler system for application to vegetation. The applicator has no moving parts, and has a simplified design.

Abstract: A method and apparatus for hydraulically macerating and recovering soluble component from a solid material such as waste solid propellant that is semihard. The solid material is fed into a perforated enclosure where it is held until it is macerated such that it can pass through perforations in the enclosure. While held in the enclosure, the solid material is agitated and exposed to jets of liquid solvent under a pressure which is equal to at least about 1000 psig to thereby macerate the solid material and force it through the perforations and to dissolve soluble component such as ammonium perchlorate from solid propellant. In one embodiment, the propellant residue is conveyed to a residue discharge end of the apparatus by a sloping helical conveyor. The helical conveyor provides individual contact stages for counter-current extraction and washing of ammonium perchlorate from the residue with recycled solvent.

Abstract: A specially shaped vessel containing a mixture of solid matter and liquid in which fresh liquid and fresh solid matter are introduced at one end and the processed liquid and solid matter are extracted at the other end. When such a vessel stands, both ends act as the two sides of a communicating vessel arrangement. The liquid levels are always the same on both sides of said vessel. Liquid is poured out from only one end through a spout equipped with a strainer to prevent the solid matter from leaving the vessel. Both ends are covered by a separate lid. To add fresh liquid and solid matter and to extract steeped solid matter, the lid covering the proper end is taken off, while the vessel is standing. To pour liquid fully processed, the lids are left in place, but the outlet lid needs only be turned slightly. As needed, both fresh liquid and solid matter to be steeped are introduced through the inlet end.

Abstract: A device for controlled feeding of a water-soluble chemical into a water line having a pressure varying between a minimum and a maximum in the line. Water flows from the water line into an air impervious chemical mixing tank through a first one-way check valve. When the pressure in the line is less than the air pressure in the tank, an air reservoir in the mixing tank forces the mixture of water and chemical back into the water line through a control valve which is set at a restricted flow value with respect to the first check valve. A second one-way check valve located in the water line between the one-way check valve and the control valve prevents the contents of the mixing tank fed through the control valve from backing up toward the first one-way check valve.

Abstract: A degassing/brine tank, for use in a chlorine generator system for swimming pools, for providing a fresh saturated brine solution continuously to the electrolytic chlorine generator cells of the system and to minimize escape of chlorine gas circulating in the system. The tank, fabricated of synthetic plastic material, has a plurality of vertically separated chambers, including, at its lower end, coaxially arranged inner and outer brine pick-up chambers. The outer annular chamber, open at its lower end, communicates with a salt and water reservoir within which the tank is immersed and a filtered supply of the brine is received by the inner, lower chamber. A check valve coupled to this inner chamber controls the supply of the brine solution into a helical coil by which the saturated brine solution is furnished to the electrolytic chlorine cells.
