Abstract:

A lamp mount assembly (9) includes: a centrally located glass stem (10) having a convex surface; upper and lower banding straps (11, 13) circumferentially encompassing, and crimped to, the centrally located glass stem (10), the banding straps (11, 13) each further comprising oppositely disposed crimp portions, a first of the crimp portions being an interlocking crimp portion (12a, 12b) and a second of the crimp portions being a solid crimp portion (13a), the interlocking crimp portion of the upper banding strap (11) overlying the solid crimp portion (13a) of the lower banding strap (13); and a pair of mount frames (14) disposed about the centrally located glass stem (10), the banding straps (11, 13) holding the mounting frames (14) in place about the glass stem (10), the mounting frames (14) having a coined, concave surface substantially matching the convex surface of the glass stem (10). The banding straps including oppositely disposed crimp portions, of the present invention, reduces breakage of the glass stem.

Assignee:

NEW ENGLAND WOOD PELLET LLC - Jaffrey NH

International Classification:

F28F 5/00

US Classification:

95 66, 165 86, 95210

Abstract:

A gas-to-liquid heat exchanger is presented, where a gas is introduced directly to liquid. The liquid is exposed to the gas as a liquid film upon a series of rotating heat exchange surfaces partially submerged in a liquid reservoir. The liquid vaporizes and then re-condenses on subsequent heat exchange surfaces, such that heat is exchanged between the gas and the liquid. Particulates within the gas coalesce into the vaporized liquid and collect into the liquid reservoir as the vapor re-condenses.

US Classification:

110268, 110286, 110293, 110341

Abstract:

A solid fuel conveying system is presented. The system includes a low power agitating grate. The grate has a surface for burning solid fuel in a burner, such as a downdraft burner. The grate includes a rotating camshaft and a plurality of movable grate elements. Each movable grate element has a cam end and a slide end. A cam bore passes through the grate element cam end, and a slide bore passes through the grate element slide end. A slide pin passes through each movable grate slide bore. A plurality of cams are disposed along the rotating camshaft, with each cam disposed within a cam bore in one of the plurality of movable grates elements. A camshaft drive rotates the camshaft, thereby moving each grate element in accordance with the orientation of the cam passing through the corresponding cam bore of that grate element.

US Classification:

110293, 110118, 110341, 110101 C

Abstract:

A solid fuel gravity feed combustion device, system and method are presented. The device includes a chute having an inlet and outlet, such that the chute inlet is configured to receive multiple pellets. A floor is disposed substantially below the chute inlet, and adjacent to the chute outlet. The chute outlet is configured to accommodate a pellet pile including at least a portion of the multiple pellets disposed upon the floor, where the pile surface is oriented substantially at a pellet angle of repose.

US Classification:

122 161, 122 311, 432 29, 110267

Abstract:

An atmospheric water heating system is presented, where hot gasses from a burner are introduced directly to water. The water is exposed to the burner exhaust gasses as a film upon a series of rotating discs partially submerged in a reservoir. The water vaporizes and then re-condenses on subsequent discs, cooling the exhaust gas and heating the reservoir water. The heated reservoir water may be used to heat space heating water with a water-to-water heat exchanger. The water vapor may be used to heat environmental forced hot air with a vapor-to-air heat exchanger.
