Abstract
Abstract A termite protection system (10) for a wooden foundation structure (12) is disclosed having a plurality of perimeter pipe sections (34) which include integral nozzles orifices (66), and a plurality of interior pipes (38) with non-integral nozzles (44), for distributing a delivering termite control fluids. The pipes (34) and (38) each have a plurality of male ends (50) which can be permanently inserted into a female end (48) of another pipe (34) or (38) or accessory fittings such as "T" fittings (40) and elbow fittings (32). Longitudinal ridges (56) and (58) within each of the male ends (50) fit into receiver grooves (62) in each of the female ends (48) as an aid to orientation of the (34) and (38) and other components. The female ends (48) have interior locking teeth (64) for locking into ridge indentations (60) on the male sections (50) such that components snap together and cannot be easily disassembled. Fluids are introduced into the termite control system (10) through a service access unit (26) having a front plate (106) which has thereon data obtained from an initial system calibration such that service personnel will be informed as to the quantity of fluid and delivery pressure required to adequately protect the structure from termite infestation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A spraying system for spraying fluids, comprising: a plurality of fluid carrying tubes and a plurality of connectors for connecting said tubes together; a plurality of hanger brackets for hanging said fluid carrying tubes from a plurality of structural members of a building; a fluid introduction means through which the fluids are put into the fluid carrying tubes; and a plurality of sprayer means, connected to said carrying tubes, for spraying the fluids onto a foundation portion of said building, wherein; at least some of the sprayer means are nozzle passages through a raised external ridge portion of at least some of said fluid carrying tubes.
Claim 2
Dependent Claim
106 words
A spraying system for spraying fluids, comprising: a plurality of fluid carrying tubes and a plurality of connectors for connecting said tubes together; a plurality of hanger brackets for hanging said fluid carrying tubes from a plurality of structural members of a building; a fluid introduction means through which the fluids are put into the fluid carrying tubes; and a plurality of sprayer means, connected to said carrying tubes, for spraying the fluids onto a foundation portion of said building, wherein; at least some of the sprayer means are nozzle passages through a raised external ridge portion of at least some of said fluid carrying tubes.
Claim 3
Dependent Claim
81 words
The tubing system of claim 1 wherein: said fluid carrying tubes include a pair of diametrically opposed external ridges for adding rigidity to the fluid carrying tubes and further for aiding of alignment of the fluid carrying tubes within said connectors; and said connectors include a pair of diametrically opposed internal grooves such that said external ridges must be aligned with said internal grooves in order to insert a male end of said fluid carrying tubes into one of said connectors.
Claim 4
Dependent Claim
39 words
The tubing system of claim 2, wherein: said external ridges are of equal cross sectional size and shape such that said male end of said fluid carrying tube may be inserted into said connector in either of two orientations.
Claim 5
Dependent Claim
38 words
The tubing system of claim 2, wherein: said external ridges are of unequal cross sectional size and shape such that said male end of said fluid carrying tube may be inserted into said connector in only one orientation.
Claim 6
Dependent Claim
76 words
The tubing system of claim 7, wherein: said hanger brackets include; a holding portion adapted for at least partially encircling one of said fluid carrying pipes; a nailing hole by means of which said hanger bracket may be attached to said structural members; and a positioning collar for abutting against said structural members such that each of the plurality of said hanger brackets can be readily positioned in like fashion in relation to said structural members.
Claim 7
Dependent Claim
87 words
The tubing system of claim 5, wherein: at least some of said hanger brackets further include; a protruding ball adapted for fitting within a socket of a hanger adaptor such that said hanger bracket may be hung from said hanger adaptor, said hanger adaptor being a means for lowering said hanger adaptor such that each of the plurality of hanger brackets, if desired, may be positioned at equal heights even if each of said structural members to which said hanger brackets are attached are at unequal heights.
Claim 8
Dependent Claim
78 words
The tubing system of claim 1 wherein: said fluid carrying tubes include a plurality of male end sections with a divisional notch between each of the male end sections such that the fluid carrying tubes may be shortened, as required, by cutting at the divisional notch, thus assuring that each of the fluid carrying tubes terminates on at least one of its two ends with a male end section, even after said fluid carrying tube is thus shortened.
Claim 9
Dependent Claim
72 words
The tubing system of claim 1, wherein: said connectors include a plurality of female apertures having therein a plurality of locking teeth for fitting into a plurality of ridge indentations on a male end section of said fluid carrying tubes, such that when said male end section of said fluid carrying tube is inserted within one of said female apertures of said connectors said male end section may not be easily withdrawn.
