Abstract
Abstract An indicator which discloses the state of a rolamite which includes a housing, a band wound in reverse bights about a pair of rollers to form a cluster. The cluster moves between two positions in the housing. The present invention incorporates a shield on the side of the housing, the shield including a pair of openings which permit visual inspection of the position of the rolamite. Preferably, the rollers are color coded to enhance visual inspection. A transducer means operates the rolamite.

Claim 3
Dependent Claim
37 words
The invention of claim 1 including a vibration transducer means cooperative with said rolamite cluster means and which moves said rolamite cluster means from a first to a second position on exceeding vibrations above a certain level.
Claim 4
Dependent Claim
56 words
The invention of claim 1 including a pressure transducer means responsive to the pressure of a given source to be monitored, said transducer means including means cooperative with said rolamite cluster means for moving said rolamite cluster means from a first to a second position indicative of the exceeding of pressure of a certain set level.
Claim 5
Dependent Claim
45 words
The invention of claim 1 including pressure transducer means responsive to pressure differential acting thereon, said means cooperative with said rolamite cluster means to move said rolamite cluster means from a first to a second position indicative of exceeding pressure differentials above a certain level.
Claim 6
Dependent Claim
33 words
The invention of claim 1 wherein one of said openings in said shield means permits viewing of the end of said roller meanS when said rolamite cluster means is in the first position.
Claim 7
Dependent Claim
33 words
The invention of claim 1 wherein one of said openings in said shield means permits viewing of the end of said roller means when said rolamite cluster means is in the second position.
Claim 8
Dependent Claim
16 words
The structure of claim 1 wherein said openings in said shield are formed of transparent material.
Claim 9
Dependent Claim
17 words
The structure of claim 1 wherein said shield means is attached to the side of said housing.
Claim 10
Dependent Claim
80 words
The structure of claim 1 wherein said shield means includes two openings located such that the first opening views the end of one of said roller means when said rolamite cluster means is in one position and the second opening views none of said roller means, and wherein said second opening views the end of one of said roller means when said rolamite cluster means is in a second position and said first opening views none of said roller means.
Claim 11
Dependent Claim
18 words
The structure of claim 1 wherein the ends of said roller means are adapted to be color coded.
Claim 12
Dependent Claim
70 words
The structure of claim 1 wherein said housing includes a pair of spaced side walls and said flexible member is selectively positioned adjacent to one of said side walls by operation of said rolamite cluster means, and further including a port means formed in said side wall and so located that said rolamite cluster means controls flow through said port means on movement from the first to the second position.
Claim 13
Dependent Claim
77 words
The invention of claim 11 wherein said port means is adapted to be communicated with a pressure responsive device and a supply of pressure fluid, the elongate band closing said port means in a first condition of the transducer which is achieved by positioning said rolamite cluster means at its first position, and wherein said rolamite cluster means moves to its second position to open or expose said port means to the passage of pressure fluid therethrough.
Claim 14
Dependent Claim
47 words
The structure of claim 11 wherein said flexible member is connected at one end portion to said side wall at a distance from said port means, and said flexible member extends parallel to said wall and passes over said port means to selectively close said port means.
Claim 15
Dependent Claim
29 words
The structure of claim 11 incorporating a surrounding seal means positioned about said port means, said seal means cooperatively closing said port means on co-action with said flexible member.
Claim 16
Dependent Claim
52 words
The structure of claim 1 wherein said flexible member includes a projecting tab portion, and further including an adjustably movable sensitivity control means in said housing cooperatively arranged with said tab portion, said means creating a variable and adjustable bias acting on said flexible member on movement to one of said positions.
Claim 17
Dependent Claim
69 words
The structure of claim 1 wherein said housing includes a chamber closed to the atmosphere, said chamber having a pair of port means selectively opening thereinto with one of said port means being adapted to be connected to a remote pressure to be tested, and the other being adapted to be selectively opened and closed to form a pneumatic signal indicative of the position of said rolamite cluster means.
Claim 18
Dependent Claim
17 words
