Abstract
Abstract A switch includes an orifice connected to a fluid source, which supplies a fluid to the orifice, and an opening spaced from and substantially aligned with the orifice, The opening is connected to a device adapted to be actuated as a result of a fluid flowing from the orifice to the opening. A movable member is in the path of a gaseous flow and is adapted to respond to the gaseous flow. An apertured, displaceable element is adapted to be displaced by movement of the movable member. The displaceable element is position between the orifice and the opening in an interference path with the fluid flow. Displacement of the displaceable element to a position so that the aperture is substantially aligned with the orifice and the opening allows fluid to flow between the orifice and the opening permitting actuation of the device.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
212 words
An article of manufacture comprising, a housing including a passageway for a gaseous flow, means including spaced-apart first and second openings, the first opening adapted to be supplied with a fluid under pressure, the second opening substantially aligned with the first opening, the second opening adapted to be connected to a device adapted to be actuated from one state to another state as a result of fluid flow from the first opening to the second opening, a movable member in the path of the gaseous flow in the passageway and adapted to respond to the gaseous flow, and a displaceable element including means for allowing a fluid to pass from the first opening to the second opening and connected to the movable member and adapted to be displaced by movement of the moveable member, the displaceable element being positioned between the first opening and the second opening in an interference path with the fluid flow between the first and second opening, predetermined displacement of the displaceable element causing displacement of its means to a position of substantial alignment with the first opening and the second opening allowing the fluid to flow between the first and sEcond openings thereby allowing the device to be actuated from the one state to the other state.
Claim 2
Dependent Claim
212 words
An article of manufacture comprising, a housing including a passageway for a gaseous flow, means including spaced-apart first and second openings, the first opening adapted to be supplied with a fluid under pressure, the second opening substantially aligned with the first opening, the second opening adapted to be connected to a device adapted to be actuated from one state to another state as a result of fluid flow from the first opening to the second opening, a movable member in the path of the gaseous flow in the passageway and adapted to respond to the gaseous flow, and a displaceable element including means for allowing a fluid to pass from the first opening to the second opening and connected to the movable member and adapted to be displaced by movement of the moveable member, the displaceable element being positioned between the first opening and the second opening in an interference path with the fluid flow between the first and second opening, predetermined displacement of the displaceable element causing displacement of its means to a position of substantial alignment with the first opening and the second opening allowing the fluid to flow between the first and sEcond openings thereby allowing the device to be actuated from the one state to the other state.
Claim 3
Dependent Claim
49 words
The article of manufacture as claimed in claim 1 for providing a switching function, wherein the movable member is a pivotal member substantially perpendicular to the direction of the gaseous flow, the gaseous flow pivoting the pivotal member an amount substantially proportional to the amount of the gaseous flow.
Claim 4
Dependent Claim
33 words
The article of manufacture as claimed in claim 2 for providing a switching function, wherein the pivotal member includes means for providing a pivot axis removed from the axis of the pivotal member.
Claim 5
Dependent Claim
29 words
The article of manufacture as claimed in claim 3 for providing a switching function, the pivotal member being positioned so as to at least partially extend across the passageway.
Claim 6
Dependent Claim
50 words
The article of manufacture as claimed in claim 1 for providing a switching function, further including bias means adapted to store energy upon movement of the movable member in response to the gaseous flow and adapted to release stored energy upon at least a partial cessation of the gaseous flow.
Claim 7
Dependent Claim
21 words
The article of manufacture as claimed in claim 5 for providing a switching function, wherein the bias means is a spring.
Claim 8
Dependent Claim
24 words
The article of manufacture as claimed in claim 6 for providing a switching function, wherein the spring is in the form of a coil.
Claim 9
Dependent Claim
53 words
The article of manufacture as claimed in claim 6 for providing a switching function, further including means for adjusting the tension of the spring. 9 The article of manufacture as claimed in claim 1 wherein the displaceable element means includes a void area which is capable of allowing the fluid to flow therethrough.
Claim 10
Dependent Claim
22 words
The article of manufacture as claimed in claim 9 for providing a switching function, wherein the void area has an adjustable length.
Claim 11
Dependent Claim
50 words
The article of manufacture as claimed in claim 10 for providing a switching function, wherein the movable member includes a rod member connected thereto for providing a pivot axis, the displaceable element being connected to the rod member and adapted to be arcuately displaced by displacement of the rod member.
Claim 12
Dependent Claim
42 words
The article of manufacture as claimed in claim 11 for providing a switching function, the movable member extending at least partially across the passageway, and the displaceable element fixedly attached to a portion of the rod member projecting externally of the housing.
Claim 13
Dependent Claim
31 words
The article of manufacture as claimed in claim 12 for providing a switch function, further including a stop means carried by the housing for limiting pivotal movement of the movable member.
Claim 14
Dependent Claim
26 words
In combination, a booth and the article of manufacture as claimed in claim 1, the article adapted to respond to a gaseous flow through the booth.
Claim 15
Dependent Claim
