Abstract:

In the vertical corner transition arrangement for semi-membrane tanks disclosed in the specification, curved horizontal sides plate of a semi-membrane tank wall are welded to one side of a vertical extruded aluminum modified I-beam with a vertical tapered stiffening corner block projection on the opposite side of the extruded aluminum I-beam, and the edge of a vertical unstiffened curved cylinder section is butt-welded to the projecting edge of the vertical tapered stiffening corner block. The curved plates of an orthogonally oriented semi-membrane tank wall are welded to one side of another vertical extruded I-beam member having a projecting vertical tapered stiffening corner block welded to the opposite side with a projecting edge which is welded to the opposite edge of the vertical stiffened curved cylinder section to complete the corner of the tank.

US Classification:

22056007, 22056008, 22056011, 22056012, 22056015, 220 15, 220562

Abstract:

In the typical embodiment of the invention described in the specification, a prismatic semi-membrane LNG tank is assembled within a support carriage surrounding the top and side walls of the tank and is connected to the tank by a plurality of load bearing insulating support blocks affixed to T-shaped beams on the tank and received in channel shaped members on the support carriage. The tank is assembled within the carriage which is slidably received within a temporary supporting structure and, when the tank has been completed, the integrated carriage and the tank are transferred to the hull of a ship or other permanent support structure. A pipe tower within the tank is affixed to the bottom wall of the tank and slidably connected to a tank dome at the top of the tank which is welded to the top wall of the tank. Stop members limit downward motion of the tank tower with respect to the top wall of the tank.

International Classification:

B63B 25/08

US Classification:

114 74A, 137376, 22056008, 22056007, 62 532

Abstract:

The invention pertains generally to manufacturing and installing a semi-membrane tank for liquefied natural gas (LNG). Specifically, the invention relates to a method and apparatus for facilitating off-hull manufacturing of a completed semi-membrane LNG tank and installation of the tank in a permanent supporting structure, such as a ship's hull. Embodiments of the invention include attaching a support structure to the top and the sides of an LNG tank and attaching a support net to the support structure. The support net may be configured to support the bottom of the tank including any insulation that may be applied to the bottom. Once the support structure and support net are attached to the tank, the tank may then be moved from an assembly location to a permanent support structure where it may be permanently attached.

US Classification:

220565, 220 234, 220 232, 220 2383, 220 94

Abstract:

Embodiments of the invention relate to support arrangements for semi-membrane tank walls and, more particularly, to a universal support assembly for tanks that experience thermal expansion and contraction. One embodiment of the invention may include a tank assembly having at least one tank wall, a support structure at least partially adjacent to the wall, and a link member coupling the tank to the support structure. The link member may be configured to accommodate relative movement between the tank and the support structure through rotation. The link member may be coupled to the tank wall by a ball and socket joint and coupled to the support structure with another ball and socket joint, allowing substantially unlimited in-plane movement of the tank wall relative to the support structure.

International Classification:

US Classification:

Abstract:

A substrate for an alkaline battery separator is made of a light weight, porous, heat bonded, synthetic organic sheet material having a basis weight of less than about 35 gsm and a thickness of less than about 200 microns. The major fibrous component is synthetic pulp comprising thermoplastic polyolefin fibers having a prefused microfibrillar structure similar to wood pulp. The minor fibrous component is a high tenacity polyamide fiber having a fiber length greater than about 6 mm. The heat bonding by partial fusion of the microfibrillar polyolefin is sufficient to impart to the sheet material a wet tensile strength of at least 400 g/in. width while permitting retention of air permeability of about 100 liters per minute and more. The substrate exhibits excellent receptivity to impregnation by pore-forming battery separator coatings and is particularly well suited for use in nickel-zinc batteries.
