Abstract
Abstract An air cooling equipment for cooling containers stacked in ships' holds comprises an upright column attached to a bulkhead or some other part of the ship's structure and provided with connections adapted to cooperate with corresponding connections provided on the containers in the stack for the supply of cold air and the withdrawal of exhaust air. The column is mounted in a manner which permits its horizontal displacement towards and away from the stack of containers. Each column connection is provided with a sealing ring which can be pressed on the cooperating connection of a container to create a tight seal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
192 words
An air-cooling arrangement for cooling a single stack of containers in a hold of a ship wherein each container includes at least two connecting fittings on one side thereof to permit entry of cooling air and exit of exhaust air, said arrangement comprising: a. a vertically disposed column, b. means mounting said column for movement along a horizontal path, c. a plurality of connecting mouthpieces fixedly arranged along and projecting from one side of said column, each of said mouthpieces including a flexible sealing ring for pressing against a connecting fitting of a container to create a tight seal, d. a plurality of ducts arranged within said column for directing cooling air and exhaust air through respective of said connecting mouthpieces, and e. means for displacing said column towards and away from a single stack of containers along said horizontal path, f. whereby said mouthpieces may simultaneously be pressed against all of said connecting fittings of all of said containers in a stack to circulate cooling air through said containers when said column is moved towards said stack and disconnected from said fittings when said column is moved away from said stack.
Claim 2
Dependent Claim
192 words
An air-cooling arrangement for cooling a single stack of containers in a hold of a ship wherein each container includes at least two connecting fittings on one side thereof to permit entry of cooling air and exit of exhaust air, said arrangement comprising: a. a vertically disposed column, b. means mounting said column for movement along a horizontal path, c. a plurality of connecting mouthpieces fixedly arranged along and projecting from one side of said column, each of said mouthpieces including a flexible sealing ring for pressing against a connecting fitting of a container to create a tight seal, d. a plurality of ducts arranged within said column for directing cooling air and exhaust air through respective of said connecting mouthpieces, and e. means for displacing said column towards and away from a single stack of containers along said horizontal path, f. whereby said mouthpieces may simultaneously be pressed against all of said connecting fittings of all of said containers in a stack to circulate cooling air through said containers when said column is moved towards said stack and disconnected from said fittings when said column is moved away from said stack.
Claim 3
Dependent Claim
46 words
An air-cooling arrangement as defined in claim 1 further comprising resilient biasing means interposed between said column and said displacing means whereby said column may be biased in the direction of said stack to maintain said sealing rings pressed against said connecting fittings on said containers.
Claim 4
Dependent Claim
29 words
An air-cooling arrangement as defined in claim 1 wherein said displacing means comprises at least one captive nut, a feed screw passing through said captive nut and drive means.
Claim 5
Dependent Claim
54 words
An air-cooling arrangement as defined in claim 3 further comprising a pair of spring members on opposite sides of said captive nut and means for retaining said spring members whereby said column may be biased in the direction of said stack to maintain said sealing rings pressed against said connecting fittings on said containers.
Claim 6
Dependent Claim
28 words
An air-cooling arrangement as defined in claim 1 wherein said displacing means comprises at least one cylinder and a piston contained within said cylinder operable by pressure fluid.
Claim 7
Dependent Claim
46 words
An air-cooling arrangement as defined in claim 5 further comprising a pair of spring members on opposite sides of said piston whereby said column may be biased in the direction of said stack to maintain said sealing rings pressed against said connecting fittings on said containers.
