Abstract
Abstract A sealed and pressurized housing for a TV camera. The camera is mounted on a cradle which includes the sealing mechanism for both ends of the housing. Both ends are sealed with conventional "O" ring seals and end plates which are secured to the cradle. Since pressure is always equalized against both end plates and they are mechanically connected, when the housing is opened, no parts can be dangerously propelled upon release of the pressure. The cradle is also mounted so that, despite the internal pressure, it can be rotated relative to the fixed outer casing in order to adjust the angle of the camera to the horizontal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A pressurized camera housing which permits safely opening the pressurized housing comprising: a leak tight casing with at least two separated closable openings; an internal structure which fits within the casing and to which are attached closure means for each of at least two separated openings, the closure means being located on the internal structure with a fixed separation so that they move together and act to simultaneously close and open the openings with which each closure means is associated; sealing means to seal the closable openings; and means to pressurize the housing with a gas when the closable openings are sealed.
Claim 2
Dependent Claim
102 words
A pressurized camera housing which permits safely opening the pressurized housing comprising: a leak tight casing with at least two separated closable openings; an internal structure which fits within the casing and to which are attached closure means for each of at least two separated openings, the closure means being located on the internal structure with a fixed separation so that they move together and act to simultaneously close and open the openings with which each closure means is associated; sealing means to seal the closable openings; and means to pressurize the housing with a gas when the closable openings are sealed.
Claim 3
Dependent Claim
30 words
The camera housing of claim 1 wherein one of the openings is constructed and located to serve as the access opening through which a camera is placed within the housing.
Claim 4
Dependent Claim
18 words
The camera housing of claim 1 wherein the internal structure is constructed to accept and hold a camera.
Claim 5
Dependent Claim
23 words
The camera housing of claim 1 wherein the internal structure is constructed so that it may be removed and separated from the casing.
Claim 6
Dependent Claim
21 words
The camera housing of claim 1 wherein one closure means is adjacent to a transparent window attached to the internal structure.
Claim 7
Dependent Claim
18 words
The camera housing of claim 1 where the closable openings are located at opposite ends of the casing.
Claim 8
Dependent Claim
47 words
The camera housing of claim 1 wherein the casing is an elongated structure with circular closable openings at opposite ends of the casing; the sealing means are seals constructed with "O" rings; and the internal structure is a rotatable cradle to which a camera can be attached.
Claim 9
Dependent Claim
94 words
A camera housing comprising: a leak tight casing with at least two separated closable openings; and an internal structure which fits within the casing and to which are attached closure means for each of at least two separated openings, the closure means being located on the internal structure so that they each act to close and open the openings with which each closure means is associated; wherein the internal structure is constructed so that it can be rotated relative to the casing while the closable openings are sealed and while maintaining the sealed condition.
Claim 10
Dependent Claim
94 words
A camera housing comprising: a leak tight casing with at least two separated closable openings; and an internal structure which fits within the casing and to which are attached closure means for each of at least two separated openings, the closure means being located on the internal structure so that they each act to close and open the openings with which each closure means is associated; wherein the internal structure is constructed so that it can be rotated relative to the casing while the closable openings are sealed and while maintaining the sealed condition.
