Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
56 words
A water inlet device adapted for liquids flowing therethrough and subject to becoming clogged comprising an enclosure including a top and a bottom associated therewith, means to connect a pipe to said enclosure, a source of pressurized substance, and means to connect said source to said enclosure and discharging therein to blow out any clogged materal.
Claim 2
Dependent Claim
56 words
A water inlet device adapted for liquids flowing therethrough and subject to becoming clogged comprising an enclosure including a top and a bottom associated therewith, means to connect a pipe to said enclosure, a source of pressurized substance, and means to connect said source to said enclosure and discharging therein to blow out any clogged materal.
Claim 3
Dependent Claim
40 words
A water filter means of the type having an inside screen, having a means to rotate at least one internal propeller blade within said filter to pulverize sediment caught in said filter thereby being unrestrictive to the flow of liquids.
Claim 4
Dependent Claim
40 words
A water filter means of the type having an inside screen, having a means to rotate at least one internal propeller blade within said filter to pulverize sediment caught in said filter thereby being unrestrictive to the flow of liquids.
Claim 5
Dependent Claim
24 words
Apparatus as in claim 1 having said pressurized substance connected to a seperate pipe attached to the water inlet discharging into the inlet means.
Claim 6
Dependent Claim
13 words
Apparatus as in claim 1, wherein said source is a hand operated pump.
Claim 7
Dependent Claim
27 words
Apparatus as in claim 2 having a plurality of propeller blades spaced apart within the water filter, connected to a rotating shaft, operated by hand turning means.
Claim 8
Dependent Claim
27 words
Apparatus as in claim 2 having said propeller on a shaft connected within said filter and turned by electric motor means mounted on to said water filter.
Claim 9
Dependent Claim
81 words
A water inlet device adapted for liquids flowing therethrough and subject to becoming clogged comprising an enclosure including a top and a bottom associated therewith, means to connect a pipe to said enclosure, a source of pressurized substance, and means to connect said source to said enclosure and discharging therein to blow out any clogged material having a signal responsive electrical alarm means connected to said enclosure and a warning light that indicate a warning system when said inlet is clogged.
Claim 10
Dependent Claim
81 words
A water inlet device adapted for liquids flowing therethrough and subject to becoming clogged comprising an enclosure including a top and a bottom associated therewith, means to connect a pipe to said enclosure, a source of pressurized substance, and means to connect said source to said enclosure and discharging therein to blow out any clogged material having a signal responsive electrical alarm means connected to said enclosure and a warning light that indicate a warning system when said inlet is clogged.
Claim 11
Dependent Claim
38 words
Apparatus as in claim 1 having a vacuum gauge and switch connected electrically to said water inlet device that operates at a preset vacuum condition when said inlet device is clogged releasing said pressurized substance to unclog it.
Claim 12
Dependent Claim
43 words
Apparatus as in claim 1 having an electric valve connected to a pressurized means operated by a vacuum control that controls the release of said pressurized substance electrically, opening in one position and closing said valve in another position when said clogging occurs.
Claim 13
Dependent Claim
20 words
Apparatus as in claim 1 having pre-filled pressurized matter in throwaway and refillable means for pressurizing said water inlet means.
Claim 14
Dependent Claim
33 words
Apparatus as in claim 1 having a propeller in the inlet strainer attached to a turning shaft secured to an inlet device electrically and hand driven to discharge foreign matter from said inlet.
Claim 15
Dependent Claim
24 words
Apparatus as in claim 2 having a signal responsive electrical alarm means and a warning electrical lamp actuate when said water filter becomes clogged.
Claim 16
Dependent Claim
29 words
Apparatus as in claim 2 having a vacuum gauge and switch connected electrically to said water filter means that operates said internal propeller when said water filter becomes clogged.
Claim 17
Dependent Claim
30 words
Apparatus as in claim 2 wherein said water filter is connected to an electrically operated valve that opens when said water filter becomes clogged permitting the ejection of clogged material.
Claim 18
Dependent Claim
48 words
Apparatus as in claim 2 wherein said water filter means is connected to a vacuum control and a pressurized substance so that when said water filter becomes clogged the vacuum control will release the pressurized substance into said water filter to clean and unclog it internally and externally
