Abstract: The invention relates to a heat exchanger of the fumes-water type configured to couple with a burner for the manufacture of boilers for domestic or industrial use. The heat exchanger is essentially constituted of an exchanging body (2) made of die-cast aluminium with two half-shells (2a and 2b), to be mounted in a mutually opposing fashion, and enclosed within a casing (3), made of a plastic or aluminium material, formed of two half-parts (3 a and 3b) to couple in order to contain therewithin the exchanging body (2), thus constituting two seats, one internal one for the flow of fumes and the other, external, one for the flow of water, which runs upwards from the bottom, passing all around the exchanging body (2) with a mixed route (partly parallel and partly spiral). The exchanger in question is of the "cross flow" type, i.e. the input on the water side corresponds with the heat exchanger fumes output and allows high heat exchange performance.

Title: Enclosed proximity switch assembly
Inventor: MERRIFIELD GREGORY CURTIS
IPC: F16K37/00
Filed: 2012-04-25
Abstract: An enclosed proximity switch assembly includes a top enclosure and a bottom enclosure that are coupled to form an interior volume. A shaft protrusion upwardly extends from a top surface of the top enclosure, and an interior bore portion having an enclosed volume is defined within the shaft protrusion to form a portion of the interior volume. A first end of a vertical shaft is rotatably disposed within the interior bore portion such that the shaft rotates relative to the top and bottom enclosures. A samarium cobalt target magnet is coupled to the shaft, and the target magnet interacts with a samarium cobalt driver magnet within a proximity switch when the target magnet is rotated within a predetermined distance of a top portion of the proximity switch. The interaction causes a switch to move from a first state to a second state, or vice versa.

Abstract: The invention relates to a raiser (2) for skidpan practice with motorcycle, comprising a supporting portion (3) with support wheels (5a-c) and a raising portion (6). The raising portion (6) is attachable to the front wheel of the motorcycle in such a way that it allows the front wheel to rotate around a first rotational axis. The raising portion is raisable and lowerable with respect to the supporting portion. The raising portion is rotatable around a second axis of rotation that essentially extends in the direction of motion of the front wheel, allowing the raiser to be used with motorcycles as they lean sideways in curves. In one embodiment, the second axis of rotation of the raiser is arranged below the upper end of the supporting wheels or below the rotational axes of the supporting wheels. This may for example be achieved if the supporting portion (3) is constituted by a supporting frame (3) receiving the front wheel and if the support wheels (5a-c) are mounted on support wheel carriers (11a-c) that extend upwards above the supporting frame (3). The invention further relates to a device for skidpan practice with a motorcycle, comprising a pair of supports (12a-b) that prevents the motorcycle from falling over, and such a raiser (2).

Title: Process for the production of furfural
Inventor: FAGAN PAUL JOSEPH
IPC: B01J29/82
Filed: 2012-12-28
Abstract: Furfural is produced by mixing an aqueous feedstock solution containing C5 sugar and/or C6 sugar with a heated, high boiling, water-miscible solvent, such as sulfolane, and a soluble acid catalyst. Furfural product and water are distilled off through a multistage distillation column, leaving non-volatile solvent behind. Typical furfural yields with sulfolane as the reaction solvent are about 80% at as high as 99% conversion. Also, certain by-products (e.g., humins) solubilized in the reaction solvent can be precipitated by addition of water or aqueous feedstock solution and then removed by filtration, thereby providing a convenient and effective way of removing these undesirable byproducts from the reaction mixture.
