A fertilizer derived from an organic source and a method of making are provided. The fertilizer of the present invention advantageously has a nitrogen content greater than 4%. The method of making the fertilizer also produces potable water.

Organic liquid fertilizer

A fertilizer derived from an organic source and a method of making are provided. The fertilizer of the present invention advantageously has a Nitrogen content greater than 4%. The method of making the fertilizer also produces potable water.

Organic liquid fertilizer and process of making

The subject invention described herein is directed to an improved fluid powered system for dispensing a selectively variable proportion of additives into a primary fluid supply line such as is commonly encountered in the firefight industry where it is desirable to proportion foam concentrates into a water line. The subject invention features a water driven motor that is integral to a variable displacement additive pump. A proportioning adjustment allows the solution % to be adjusted. Once set, the additive percent varies in direct proportion to the water flow rate in order to maintain a nearly constant solution percentage over a broad flow range.

Additive proportioning system

A fire fighting nozzle for extinguishing industrial scale fires including improved automatic pressure regulating features, enhanced educting features including central and peripheral channeling for foam concentrate, and combining with a capacity to throw dry chemical. Improved pressure regulating features include a double acting baffle and preferably a relief valve. Method and apparatus for automatically metering an additive such as foam concentrate into a conduit having a variably flowing fire fighting fluid therethrough, the conduit including a discharge device, proximate or downstream.

Fire fighting nozzle and method including pressure regulation, chemical and eduction features

A selectively automatic fire fighting nozzle a method of use including adjustable means (ST) of limiting a range of automatic adjustment (B) of a discharge orifice of the nozzle, providing an option of selecting a constant pressure for a first fraction of a discharge window and selecting a relatively constant flow for a second fraction.

A self-metering, automatic (i.e. pressure regulating) industrial-scale fire fighting nozzle, with or without self-eduction, for self-metering a concentrate in accordance with varying liquid flow through the nozzle occasioned by the pressure regulating, with additional features of having a 'ratio selectable' means for self-metering for different selected additive concentrations or mixing ratios and of having a mechanical flowmeter.

Ranger/hybrid automatic self-metering nozzle, with ratio-selectable and flow meter features

An industrial scale fire fighting nozzle and method, the nozzle having a selectively adjustable discharge gap and providing for gap coordinated, independently selectable additive proportioning ratio selection, the method including discharging fire fighting fluid at a selectively adjustable flow rate with an independently selectable, gap coordinated adjustable additive proportioning ratio, and use of reinforced high temperature polymer for at least a barrel element or a bafflehead element component.

Selectable fixed flow large scale fire fighting nozzle with selectable additive proportioning and light weight cost effective construction

System for automatic self-proportioning of foam concentrate into fire fighting fluid variable flow conduit

A fire fighting nozzle for extinguishing industrial scale fires including improved automatic pressure regulating features, enhanced educting features including central and peripheral channeling for foam concentrate, and combining with a capacity to throw dry chemical. Improved pressure regulating features include a double acting baffle and preferably a relief valve.

A fire fighting nozzle for extinguishing industrial scale fires including improved automatic pressure regulating features, enhanced educting features having central ( ) and peripheral channeling ( ) for foam concentrate, combined with a capacity to throw dry chemicals. The improved pressure regulating features include a spring ( ) loaded double acting baffle ( ), that is positioned by fire fighting fluid in communication with a hydraulic chamber, the hydraulic chamber is preferably controlled by a relief valve ( ).

Fire fighting nozzle and method including pressure regulation, chemical and education features

A fire fighting fluid proportioning system and method including a fire fighting fluid conduit in fluid communication with a fire fighting fluid regulating valve and a venturi, the venturi in fluid communication with a valve source of fire fighting foam concentrate, and having a pilot valve connected directly or indirectly to the regulating valve and the concentrate source valve and adapted to adjust, directly or indirectly, the regulating valve and the source valve in response to a sensed indicia of fire fighting fluid pressure in the conduit.

Self metering foam proportioning system

An additive supply mechanism and method for fire fighting mechanisms, such as fire fighting trucks, including an additive supply conduit, an additive pump means, a recirculation line having a balanced pressure valve throttling the line, at least one sensor measuring recirculation line flow and an additive pump output control apparatus responsive to measured recirculation line flow.
