Abstract: A method for making an intermediate component (11) of a single use capsule (1) for extraction or infusion beverages includes the step of: arranging a first strip (S1) of thermoformable filtering material above rigid bodies (2); joining the first strip (S1) of thermoformable filtering material to the rigid bodies (2) at respective rims (7); forming the first strip (S1) of thermoformable filtering material to achieve a filter (8) that defines a chamber (5) for a dose of product. A machine for making intermediate components of single use capsules (1) for extraction or infusion beverages includes: a feeding system (40); a transport system (50); a joining station (60); and a forming station (70).

Abstract: An oven includes a body portion and a door engageable with the body portion, the body portion being generally cylindrical in shape having two lateral sides each formed with a circular groove, each of the lateral sides having two vertical slots extending upwardly from the circular groove, the door having two flanges at two ends thereof each provided with two protuberances at an inner side thereof, the protuberances being configured to be slidable within the circular groove and the vertical slots, whereby the door can be dismantled from the body portion for removing the grease and other drippings extracted from food during the roasting process.

Abstract: An improved vent damper for oil or natural gas-fired hot water heaters includes a damper assembly incorporated into the exhaust duct above a hot water heater, and contains a lightweight, floating poppet closure slidably mounted on a reduced-diameter exhaust pipe. When the hot water heater's main burner is operating, hot exhaust gasses lift the floating poppet closure, and the gasses escape through the gap thereby created around its base. These exhaust gasses are then vented to the outside air via an exhaust duct. When the main burner is turned off again, the floating poppet closure falls back again to its original (closed) position, thereby blocking the exhaust duct and preventing cool room air from circulating through the heater and its central core. Pilot light exhaust gasses are able to continuously escape through the reduced-diameter exhaust pipe even when the floating poppet closure is in the closed position.
