Abstract: An improved band seal clamp for clamping of tubular members is disclosed which features a band-like clamping member having slots formed in its ends for interaction with bolts held rigidly in holes formed in a spacing member disposed between the ends of the clamp. The ends of the band are shaped to define surfaces at an angle with respect to the surface of the tubular members which coact with force bars having corresponding shapes. Throughbolts fit through the slots in the band, holes in the force bars and the holes in the spacing member, so that upon tightening of the bolts the ends of the band clamp are forced outward, thus exerting a compressive stress on the tubular member.

Abstract: A wall-like component which is supported at opposite ends and exposed to thermal stresses has an elongated bilateral enlargement extending substantially parallel to a plane in which the component lies. The enlargement is oriented substantially perpendicularly to an imaginary distance line between the opposite ends. An elongated cavity extends within and codirectionally with the enlargement. The cavity is offset with respect to the enlargement in the direction of one of the ends of the component. The cavity further has a dimension--measured in a direction perpendicular to the plane of the component--which is greater than the thickness of a component portion adjoining the enlargement. As a result, upon breakage of parts of the enlargement under the effect of forces derived from heat-caused expansion of the material of the component, there is obtained a free edge of the component portion and a trough-like part formed together by remaining parts of the enlargement and the cavity for receiving the free edge.

Abstract: A heat-expandable tube-like component includes a tubular wall having a length dimension and defining an inner space; and a septum attached to the tubular wall and dividing the inner space into separate, longitudinally extending passages.

Abstract: A sealed, sterile connection may be provided between a pair or more of containers having transparent, flexible, thermoplastic sealed walls, each of which contains an opaque, relatively rigid, hollow sealing member in the general shape of a truncated cone, open at both ends. The containers are brought together into facing contact, and the hollow sealing members are nested together with portions of the transparent walls of the containers positioned therebetween. The nested, sealing member cones are irradiated with infrared or the like through the transparent container walls to heat the nested sealing members. As a result of this, heat is conducted to the portions of the transparent walls between the nested sealing members, to seal the portions of the transparent walls together in an annular area between the sealing means. A portion of the transparent walls retained in the nested sealing members may then be torn away to make a sterile connection between the two containers.
