Appl. No.:

29/348861

Inventors:

Robert E. Walter - Elk Grove Village IL, US
John Whitworth Engel - Smithville TX, US

Assignee:

Engel Ballistic Research - Smithville TX

International Classification:

US Classification:

D22116

US Patent:

20020000442, Jan 3, 2002

Filed:

Jan 29, 2001

Appl. No.:

09/771076

Inventors:

John Howard - Northwoods IL, US
Charles Nichols - Plainfield IL, US

Robert Walter - Bolingbrook IL, US

International Classification:

A47J027/00
A47J036/00
A47J037/01

US Classification:

220/573100

Abstract:

A nestable, dual-ovenable cooking pan () made of thin, thermoformed plastic sheet material has an interlocking beam and skin structure including a peripheral frame () in its floor () and vertical horizontal ribs () in its walls (). This structure cooperates with integral handles () in a top flange () to enhance strength and rigidity. The handles have uniform or non-uniform undulations () which, in addition to providing rigidity, increase the effective thickness of the handles and allow the pan to be comfortably picked up and carried when hot. The handles cool relatively quickly. The undulations give the handles a purchase and feel similar to those of thicker handles of ceramic permanent cookware. The plastic sheet material is preferably nucleated CPET.

International Classification:

H01F 722

US Classification:

335216

Abstract:

A superconducting magnetic energy storage apparatus comprising a cylindrical superconducting coil; a cylindrical coil containment vessel enclosing the coil and adapted to hold a liquid, such as liquefied helium; and a cylindrical vacuum vessel enclosing the coil containment vessel and located in a restraining structure having inner and outer circumferential walls and a floor; the apparatus being provided with horizontal compression members between (1) the coil and the coil containment vessel and (2) between the coil containment vessel and the vacuum vessel, compression bearing members between the vacuum vessel and the restraining structure inner and outer walls, vertical support members (1) between the coil bottom and the coil containment vessel bottom and (2) between the coil containment vessel bottom and the vacuum vessel bottom, and external supports between the vacuum vessel bottom and the restraining structure floor, whereby the loads developed by thermal and magnetic energy changes in the apparatus can be accommodated and the structural integrity of the apparatus be maintained.

International Classification:

E04B 228
E04B 920
E04H 700

US Classification:

5250606

Abstract:

A method of providing a suspended ceiling in a storage tank involves building a deck on the floor of the storage tank and raising it into place by using an external hoist mechanism. The hoist mechanism is connected to the deck by cutting holes in the roof of the tank and feeding cables through the holes. The cables are attached to a series of extenders, such as metal bars, that are fixed to lift points on the deck. The extenders are long enough so that, once the ceiling is raised to its final position, portions of the extenders project into the holes in the roof. The ceiling is then fixed in position by securing the extenders to the roof. After the ceiling is secured in position, the holes in the roof are sealed.

International Classification:

H01F 722

US Classification:

335216

Abstract:

This invention relates to superconducting magnetic storage (SMES) apparatus made of repetitious modular units or modules which support a superconducting electrical magnet and a fluid and which are capable of efficient load transfer and are mass producible. The invention also relates to a method for making a modular SMES apparatus.
