Abstract
Abstract A fluid distribution system including a main conduit and one or more branch conduits communicating therewith, each of the branch conduits having at least one normally closed nozzle with a solenoid actuated valve, the solenoids being connected by means of a circuit through a timer to an associated source of electrical power together with an aerosol container containing a pressurized fluid and connected to the main conduit so that the conduits are filled with the pressurized fluid under equilibrium conditions with the container contents whereby periodic actuation of the solenoids is obtained simultaneously through the timer for opening all of the nozzles simultaneously to spray areas adjacent the nozzles with a quantity of the fluid.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
196 words
A distribution system for a combination of liquid and gas comprising: a. a main conduit through which said combination may flow; b. a plurality of branch conduits through which said combination may flow connected to said main conduit at one end and closed at the other end; c. a plurality of spray nozzles connected on each of said plurality of branch conduits; d. a plurality of valve means, one on each of said plurality of spray nozzles, operable to control flow of said combination through each of said plurality of spray nozzles; e. flow control means for introducing said combination of a liquid and a gas into said main conduit and thereby to said plurality of branch conduits including a supply source, and for maintaining said combination of a liquid and a gas in similar proportions in said main conduit and said plurality of branch conduits as it is in said supply source; and f. condition responsive means operative to respond to a predetermined condition by opening a pre-determined number of said plurality of valve means thereby allowing flow of said combination of liquid and gas through a pre-determined number of said plurality of spray nozzles.
Claim 2
Dependent Claim
196 words
A distribution system for a combination of liquid and gas comprising: a. a main conduit through which said combination may flow; b. a plurality of branch conduits through which said combination may flow connected to said main conduit at one end and closed at the other end; c. a plurality of spray nozzles connected on each of said plurality of branch conduits; d. a plurality of valve means, one on each of said plurality of spray nozzles, operable to control flow of said combination through each of said plurality of spray nozzles; e. flow control means for introducing said combination of a liquid and a gas into said main conduit and thereby to said plurality of branch conduits including a supply source, and for maintaining said combination of a liquid and a gas in similar proportions in said main conduit and said plurality of branch conduits as it is in said supply source; and f. condition responsive means operative to respond to a predetermined condition by opening a pre-determined number of said plurality of valve means thereby allowing flow of said combination of liquid and gas through a pre-determined number of said plurality of spray nozzles.
Claim 3
Dependent Claim
18 words
A distribution system according to claim 1 wherein said combination of liquid and gas is a fire retardent.
Claim 4
Dependent Claim
38 words
A distribution system according to claim 1 wherein said flow control means furTher comprises a check valve on said main conduit located near said supply source whereby flow of said liquid back into said supply source is prevented.
Claim 5
Dependent Claim
97 words
A distribution system according to claim 1 wherein said plurality of branch conduits are closed at said other end by a normally closed valve which is operable to be opened when said combination of a liquid and a gas is introduced into said main conduit and said plurality of branch conduits by said flow control means whereby any air or vapor trapped within said main conduit or said plurality of branch conduits may be expelled therefrom, thereby permitting a similar proportion of said combination of a liquid and a gas to be established throughout said distribution system.
Claim 6
Dependent Claim
43 words
A distribution system according to claim 2 wherein said condition responsive means comprises a plurality of thermal relays controlling said plurality of valve means and thereby controlling flow of said combination of liquid and gas through each of said plurality of spray nozzles.
Claim 7
Dependent Claim
97 words
A distribution system according to claim 3 wherein said plurality of branch conduits are closed at said other end by a normally closed valve which is operable to be opened when said combination of a liquid and a gas is introduced into said main conduit and said plurality of branch conduits by said flow control means whereby any air or vapor trapped within said main conduit or said plurality of branch conduits may be expelled therefrom, thereby permitting a similar proportion of said combination of a liquid and a gas to be established throughout said distribution system.
Claim 8
Dependent Claim
38 words
A distribution system according to claim 5 wherein said flow control means further comprises a check valve on said main conduit located near said supply source whereby flow of said liquid back into said supply source is prevented.
Claim 9
Dependent Claim
97 words
A distribution system according to claim 7 wherein said plurality of branch conduits are closed at said other end by a normally closed valve which is operable to be opened when said combination of a liquid and a gas is introduced into said main conduit and said plurality of branch conduits by said flow control means whereby any air or vapor trapped within said main conduit or said plurality of branch conduits may be expelled therefrom, thereby permitting a similar proportion of said combination of a liquid and a gas to be established throughout said distribution system.
Claim 10
Dependent Claim
42 words
A distribution system according to claim 1 wherein said flow control means further comprises a plurality of trap means located in the interior of said plurality of branch conduits and operative to prevent the flow-back of said mixture of liquid and gas.
Claim 11
Dependent Claim
78 words
A distribution system according to claim 9 wherein said plurality of valve means comprises a plurality of solenoid actuated valves, a plurality of circuit means for connecting said plurality of solenoid actuated valves to a source of electrical power, and wherein a timing means is located in said plurality of circuit means for periodically energizing said plurality of solenoid actuated valves in order to allow flow of said combination of liquid and gas to said plurality of nozzles.
Claim 12
Dependent Claim
87 words
A distribution system according to claim 10 wherein said plurality of circuit means includes a plurality of switches operatively associated with all of the plurality of solenoid actuated valves in each of said plurality of branch conduits for disconnecting the plurality of solenoid actuated valves in a selected branch conduit from said source of electrical power and a valve in each of said plurality of branch conduits for interrupting the flow of said combination of liquid and gas between a selected branch conduit and said main conduit.
