Abstract

A centrifugal potting apparatus has one or more rotators for holding housings filled with hollow semi-permeable filaments. Potting agent containers with radially-directed outlets are mounted on the rotators. Tubing connects the container outlets to potting case inlets at the ends of the filament-filled housings. Centrifugal forces during rotation force the potting agent through the tubing and into the ends of the housings.

Claims

1. Centrifugal potting apparatus comprising:

a rotator adapted for rotation about an axis of rotation;

a housing mounted on said rotator and disposed essentially symmetric with respect to said axis of rotation,

said hausing being provided with a pair of potting cases each spaced from said axis of rotation and adapted to receive a potting agent therein upon rotation of said rotator;

a pair of individual container means respectively associated with said pair of said potting cases and each adapted for holding a separate source of a potting agent to be delivered to the corresponding potting case under centrifugal force produced by rotation of said rotator, each of said container means being secured to a side of said rotator and in spaced relationship to said axis of rotation; and

tube means operably coupling said pair of container means with the respectively associated potting cases for delivering potting agent from the former to the latter upon rotation of said rotator.

2. The apparatus of claim 1, wherein:

said pair of potting cases and said pair of individual container means are disposed essentially coplanar, and

each of said pair of container means are provided with an opening therein having the longitudinal axis thereof extending in a direction radially outward from said rotation axis of rotation.

3. The apparatus of claim 1, including:

a plurality of said housings and a plurality of said pairs of container means respectively associated with the corresponding ones of said potting cases,

said rotator including a longitudinal slot therein extending in a direction essentially aligned with said rotation axis of rotation and having each of said housings mounted therethrough in aligned side-by-side relationship to each other.

4. The apparatus of claim 1, including:

a plurality of said rotators;

first and second spaced apart support means for rotatably mounting the opposite extremities of each of said plurality of rotators,

said first and second support means being mounted for revolution about a reference axis spaced from each of said rotational axis of said plurality of rotators; and

means operably coupled with at least one of said first and second support means for selectively driving each of the latter to revolve about said reference axis.

5. Centrifugal potting apparatus, comprising:

a rotator adapted for rotation about an essentially vertical axis;

at least one potting housing mounted on said rotator and provided with a pair of potting cases radially spaced from said vertical axis;

at least a pair of individual containers respectively associated with said pair of potting cases and each adapted for holding a separate quantity of a potting agent therein to be delivered to the corresponding potting cases under centrifugal force produced during rotation of said rotator, said pair of containers being respectively secured to opposite sides of said rotator in radially spaced relationship to said vertical axis and in angularly offset relationship to the respectively associated potting cases about said vertical axis, each of said containers including an aperture therein extending radially outward from said vertical axis; and

tube means operably coupling each of said apertures with the respectively associated potting cases for delivering potting agent from the container to the corresponding potting cases upon rotation of said rotator.

6. The apparatus of claim 5, including:

circularly shaped turret structure adapted for rotation about a central axis of rotation; and

a plurality of said rotators mounted at circumferencially spaced positions along the periphery of said turret structure for rotation about their corresponding vertical axis, said plurality of rotators also being rotatable about said central axis upon rotation of said turret structure.
