Appl. No.:

12/327273

Inventors:

Abtar Singh - Kennesaw GA, US
Thomas J. Matthews - Fayette ME, US
Stephen T. Woodworth - Woodstock GA, US

Assignee:

Emerson Retail Services, Inc. - Kennesaw GA

International Classification:

F25B 49/00

US Classification:

62129, 62217, 62225

Abstract:

A system includes a compressor temperature sensor that generates a compressor discharge temperature signal corresponding to a compressor of a refrigeration system, a compressor pressure sensor that generates a compressor discharge pressure signal corresponding to the compressor, and a controller processing the signals over a predetermined time period. The processing includes calculating a discharge saturation temperature based on the compressor discharge pressure signal, calculating compressor superheat data based on the compressor discharge temperature signal and the discharge saturation temperature, accumulating the compressor superheat data over the predetermined time period, and comparing the accumulated compressor superheat data to a predetermined threshold. The controller generates an alarm indicating a compressor fault based on the comparing.

Assignee:

Kawneer Company, Inc. - Norcross GA

International Classification:

E04C 300
E04D 136

US Classification:

52464

Abstract:

A snap-in glazing pocket filler is disclosed for use with a structural frame member having an unused glazing pocket. The glazing pocket filler includes an elongated metal plate having front and rear faces and being dimensioned to cover said glazing pocket. A pair of plastic retaining legs are fastened to the elongated metal plate and extend rearwardly and outwardly thereof to engage the walls of the glazing pocket. In one aspect of the invention, the plastic retaining legs are pivotably fastened to the metal plate such that when the glazing pocket filler is snapped into the glazing pocket, the legs pivot outwardly to facilitate engagement of the legs with the pocket walls. In the disclosed embodiment, the plastic retaining legs comprise rigid stems having flexible barbs projecting outwardly therefrom to engage the pocket walls. The flexible barbs and rigid stems are coextruded of flexible and rigid polyvinyl chloride.

Kawneer Company - Norcross GA

International Classification:

B23B 4902

US Classification:

408 1R

Abstract:

An template positioning jig. In a preferred embodiment, a deformable member is used which is deformed inwardly along a first axis such that it bulges or otherwise deforms outwardly along a second axis, until contacting the sides of a cavity, whereupon it tends to center itself within the cavity. An operably associated template is likewise centered or otherwise positioned as desired relative to the cavity.

Appl. No.:

7/229127

Inventors:

Thomas E. Matthews - Lilburn GA

Assignee:

Kawneer Company, Inc. - Norcross GA

International Classification:

E04B 228

US Classification:

52235

Abstract:

The invention provides a thermal break configuration in a flush glazed, two-piece mullion which permits a reduced face dimension without reducing the depth of the glazing channels of the mullion. The invention is directed to a thermal break segmented filler assembly for the shallow glazing pocket in narrow flush glazed two-piece framing for curtainwalls, storefronts, and the like. The two-piece mullions have a major portion and a filler portion, both of which are extruded profiles. The filler assembly incorporates a thin thermal break which makes it possible to reduce the mullion face dimension and still provide a glazing pocket depth equal to that of conventional flush glazed thermal framing. The thin thermal break of the filler assembly includes a plastic channel extrusion having rigid upturned legs with relatively soft barbs which engage channels in aluminum extrusion filler halves. The thermal break filler element is snap fit onto and between the filler halves to form a three-piece filler assembly.

Abstract:

A watercraft matting is described that includes a bottom surface configured to come into contact with a watercraft surface, a top surface having a plurality of recessed portions disposed between a plurality of protruding portions, where the protruding portions being formed of a non-skid material, and a phosphorescent material positioned within the plurality of recessed portions. The phosphorescent material is adapted to glow-in-the-dark when exposed to an ultraviolet light. The plurality of protruding portions may be formed of a cross-linked-closed-cell (CLCC) foam material.
