Abstract: Apparatus for injecting a reagent into a stream of pressurized rinse fluid delivered to a vacuum toilet. The apparatus is pressure-operated in response to the flow of pressurized rinse fluid, thereby eliminating the need for electric outlets or controls. The apparatus includes an orifice located in a main conduit upstream of a reagent discharge outlet. The orifice reduces the pressure of the rinse fluid thereby to unload a check valve which controls injection of the reagent into the rinse fluid stream.

Furthermore, the piping leading into the pump chamber has a relatively uniform inside surface and a tapered insert is used to reduced the cross-sectional area of the reagent extreme, thereby directing air bubbles through the pump chamber.

Abstract: A fluid mixing valve has a canister which defines a chamber divided into an upper additive subchamber and a lower carrier subchamber by a plunger and diaphragm. A pressurized carrier liquid enters the carrier subchamber through an inlet and exits the carrier subchamber through a restriction, which produces a pressure differential across the plunger piston to pressurize a supply of additive liquid held within the additive subchamber above the piston. The pressurized additive liquid is injected past an adjustable metering valve into the flow stream of carrier liquid downstream of the restriction. As the additive liquid is depleted, the volume of the additive subchamber diminishes and the extension of the plunger out of the canister increases, to provide an indication of the amount of additive left in the additive subchamber. When the supply of additive liquid is exhausted, the plunger can be manually returned so as to enlarge the additive subchamber to prepare it to receive a new supply of additive liquid.

Abstract: A lime feeder includes a metering driving vessel divided into two chambers arranged below a water inlet so that, alternatively one and the other chamber is filled with water and tilts between two end positions. The tilting movement is conducted by a carrier bar fastened in the metering vessel, to carriers that, in turn, drive a disk back and forth. The disk, in turn, feeds lime from a lime hopper with a movement back and forth. The lime powder is thereby brought to fall into the chamber of the metering vessel that has already been emptied. In this way, the lime will be wetted so that when it arrives in the stream of water, it is already suspended, which results in a more efficient dissolving of the lime.

Abstract: A pair of flapper valves are mounted in parallel to control the flow of a fluid into a reservoir. The flapper valves are opened by a first rotatable cam which is rotated through one or more complete revolutions when a float control switch in the reservoir is opened thereby indicating a drop in the level of fluid in the reservoir. Each complete revolution of the first cam actuates an impulse switch for a short duration. The impulse switch energizes a low speed memory motor and increments the output shaft of the motor. Each increment corresponds to one complete revolution of the first cam and, therefore, one unit of a fixed quantity of fluid passing through the valves. The output shaft of the memory motor rotates a second adjustable cam that controls the actuation of a switch which in turn controls a dispenser for dispensing a chemical additive into the fluid added to the reservoir.

Abstract: A funnel shaped conveyor receives containers of powdered materials and is coupled to the containers. A screen support member within the funnel receives granules from the container and supports the same above a spray nozzle. The nozzle directs a spray of liquid, such as water, against the underside of the support screen and wets the granules resting thereon, dissolving the same and causing the solution to pass through the screen.
