Filed:

Mar 3, 2000

Appl. No.:

09/517974

Inventors:

Steven V. Larson - Minneapolis MN, US

Assignee:

A.J. Manufacturing, Inc. - Bloomer WI

International Classification:

E06B 1/04

US Classification:

522041, 49400, 527931

Abstract:

A door and frame combination for an air handling unit consists of a frame, a hinged door with a hollow core filled with insulating material, and a gasket having a flexible gasket wall with anti-roll extensions. The gasket may have a friction-reducing material on its surface to assist in preventing roll-over by the closing door. Optional thermal pockets in the door and frame are filled with high-density polyurethane to provide further protection against air leakage.

International Classification:

E04H 17/16

US Classification:

256 31, 256 24, 256 6514, 256 73

Abstract:

A fencing system operable to define a barrier relative to a foundation. The fencing system includes a mount that is operable to be supported by the foundation. The mount includes an upright portion configured to extend from the foundation. The fencing system also includes a first barrier member having a lower bracket that receives the upright portion such that the mount supports the first barrier member generally upright. The fencing system also includes a second barrier member having an upper bracket that receives the upright portion such that the mount supports the second barrier member generally upright and such that the upper bracket substantially overlaps the lower bracket to limit movement of the first barrier member.

International Classification:

G09F 1500

US Classification:

40610

Abstract:

A collapsible sign, including a fixed frame, a plurality of sections hingedly and movably attached to the frame, the sign being movable the sections between a viewing position and a collapsed position. Adjacent pairs of the plurality of sections are positioned to provide an offset distance between axes of rotation located at each end of each section when the plurality of sections are in the viewing position.

Abstract:

A barrier system is used to block a travel path. The barriers block and direct paths of vehicular and pedestrian travel. The barriers may be shaped substantially as a truncated pyramid with a base surface and planar sides extending from the edges of the base surface to a top portion, where the cross-sectional area of the base surface is larger than the cross-sectional area of the top portion. The angles of inclination between the planar sides and the interior of the base surface are acute angles. The bollard can be cast from heavy dense materials. The bollard includes at least two overhanging lips on the planar sides of the barrier between the base surface and the top portion. The configurations of the bollards provide improved placement, such as with cranes, hand carts, and other devices. Molds to cast the barriers and hand carts to move the barriers are also disclosed.

C25D 11/14
H02K 5/02

Abstract:

A motor assembly including a housing with a motor portion having an opening for receiving a motor housing/stator assembly, rotor assembly, front and rear end caps and bearings, an encoder coupled to the motor, and an rear cover for enclosing the opening of the motor portion of the housing, the rear cover at least partially surrounding the encoder. At least one of an interior surface of the rear cover or an exterior surface of the encoder comprise a material having an emissivity greater than 0.9.
