Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
51 words
A purifier according to claim 1 in which the first tube is led into the container at the upper portion thereof, the second tube is led into the container at the lower portion thereof and the means to vibrate the container includes a bracket secured to the container and the engine.
Claim 2
Dependent Claim
23 words
A purifier according to claim 1 in which a valve is incorporated in the first tube between the container and the engine manifold.
Claim 3
Dependent Claim
51 words
A purifier according to claim 1 in which the engine exhaust manifold includes a conduit into which all the products of combustion from a plurality of cylinders is led and the first tube is connected to the conduit in close proximity to the area where the conduit joins the exhaust manifold.
Claim 4
Dependent Claim
27 words
A purifier according to claim 3 in which the valve is a flap valve whereby the products of combustion coming from the engine cannot enter the container.
Claim 5
Dependent Claim
26 words
A purifier according to claim 5 in which a valve is incorporated in the second tube between the source of gas under pressure and the container.
Claim 6
Dependent Claim
18 words
A purifier according to claim 6 in which the source of gas under pressure is the exhaust manifold.
Claim 7
Dependent Claim
20 words
A purifier according to claim 1 in which the vibrating means includes a diaphragm in the bottom of the container.
Claim 8
Dependent Claim
18 words
A purifier according to claim 1 in which the vibrating means is a vibrator secured to the container.
Claim 9
Independent Claim
80 words
The method of purifying the products of combustion coming from an engine comprising the steps of placing a quantity of a catalytic material within a container, vibrating the container to abrade the catalytic material to form a fine dust of said material, directing the said dust into the exhaust manifold of an engine in an area of maximum temperature of the products of combustion therein whereby the catalitic material reacts with the said products of combustion to render them non-toxic.
Claim 10
Dependent Claim
16 words
The method according to claim 10 in which gas under pressure is introduced into the container.
