Abstract
Abstract The automatic weaving looms of a textile plant are individually enveloped by hoods of acoustical insulation material suspended from hoists and sealingly engaging the floor about the associated machines. Air at controlled temperature and humidity is supplied to the interior of each hood and exhausted from that interior through a system of manifold pipes having orifices in the floor under each hood, and valves in the orifices which open automatically as the hood descends into the operative position and close when the hood is lifted.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
203 words
In an arrangement for operating a machine under controlled atmospheric conditions, the machine being supported on a floor and capable of substantially automatic operation, in combination: a. a downwardly open hood essentially consisting of acoustical insulating material and dimensioned to receive said machine therein, said hood having an annular rim about the downwardly directed opening thereof; b. hoist means for moving said hood in a vertical direction toward and away from an operative position in which said rim sealingly engages said floor; and c. atmosphere control means for maintaining in said hood an atmosphere of air at a temperature of 15* to 50* C., a relative humidity of a least 50 percent, and a pressure higher than that of the ambient atmosphere, said atmosphere control means including 1. a source of air at said temperature, humidity, and pressure, 2. a supply conduit connecting said source to the interior of said hood in the operative position of the same, 3. an exhaust conduit leading outward of said interior, 4. a valve in each of said conduits, and 5. valve-operating means responsive to movement of said hood for opening and closing said valves when the hood moves toward and away from said operating position thereof.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
19 words
a supply conduit connecting said source to the interior of said hood in the operative position of the same,
Claim 4
Dependent Claim
19 words
a supply conduit connecting said source to the interior of said hood in the operative position of the same,
Claim 5
Dependent Claim
52 words
In arrangement as set forth in claim 1, at least one of said valves being biased toward the closed position, and said valve-operating means including an abutment member positioned for engagement with said one valve when said hood approaches said operative position and for displacing the engaged valve toward the open position.
Claim 6
Dependent Claim
55 words
In an arrangement as set forth in claim 2, mounting means for securing said abutment member to said hood in each of a plurality of positions offset relative to each other in the direction of hood movement toward the operative position, and for thereby varying the displacement of said one valve toward said open position.
Claim 7
Dependent Claim
8 words
an exhaust conduit leading outward of said interior,
Claim 8
Dependent Claim
8 words
an exhaust conduit leading outward of said interior,
Claim 9
Dependent Claim
8 words
a valve in each of said conduits, and
Claim 10
Dependent Claim
8 words
a valve in each of said conduits, and
Claim 11
Dependent Claim
72 words
In an arrangement as set forth in claim 1, said source of air being effective in supplying air of a relative humidity close to 100 percent at said temperature, the atmosphere control means further comprising another source of air at said temperature and at a relative humidity of not substantially more than 50 percent, and another supply conduit connecting said other source to said interior in the operative position of said hood.
Claim 12
Dependent Claim
24 words
In an arrangement as set forth in claim 4, said conduits being located in said floor and having upwardly directed orifices in the same.
Claim 13
Dependent Claim
26 words
valve-operating means responsive to movement of said hood for opening and closing said valves when the hood moves toward and away from said operating position thereof.
Claim 14
Dependent Claim
26 words
valve-operating means responsive to movement of said hood for opening and closing said valves when the hood moves toward and away from said operating position thereof.
Claim 15
Dependent Claim
50 words
In an arrangement as set forth in claim 1, a light source mounted on said hood in said interior of the same, said hood being formed with an aperture, and a window movable relative to said hood toward and away from a position in which said window seals said aperture.
